Title: Telescoping torque reaction track device

Description:
BACKGROUND 
     Field of the Disclosure 
     This disclosure generally relates to torque restraining devices (and related systems and methods) used with power swivels and top drives in the oil and gas industry. 
     Background of the Disclosure 
     When drilling for oil or gas, a wellbore is typically drilled using a drill bit attached to the lower end of a “drill string.” The process of drilling a well typically includes a series of drilling, tripping, casing and cementing, and repeating as necessary. The process of doing well servicing on a previously drilled, completed, and producing well uses many of the same operations although rotation is only required for operations such as milling out a packer and/or sometimes for drilling the well deeper. 
     Normally, relatively large drilling rigs are used for these wells, which utilize a ‘kelly’ table and associated equipment. Rigs of this sort take up an enormous amount of surface area and are typically capable of generating rotary torques of 35,000 foot-pounds (47,460 joules) or more. 
       FIG.  1 A  shows a simplified view of a conventional drilling operation  100  using a powerful driver. A derrick  102  (or drilling rig) is configured to rotate a drill string  104  that has a drill bit  106  disposed at a lower end of the drill string  104 , typically using a driver unit  110  and associated equipment. The driver unit  110  rotates the string  104  and the drill bit  106  to do drilling or milling work downhole in the wellbore  108   
     Near the derrick  102 , a plurality of tubular members  103   a  are often stored on a pipe rack(s)  112 . The pipe rack  112  is relatively near the ground, and substantially below the rig floor  115 . Therefore, tubulars  103 ,  103   a  must be transported to the rig floor  115  joint by joint for use in drilling or servicing operations. 
     Pipe handling systems are utilized to transport the tubular  103  from the pipe rack  112  and present the tubular  103  to rig floor  115  for use by rig floor personnel. Such pipe handling systems are commonly available from rental companies, well servicing or drilling companies, and the like. These systems are typically known as pipe handlers or hydraulic catwalks, which are operated to move the tubular(s)  103  from a horizontal position on the catwalk  113 , up an inclined ramp or V-door  114 , to the rig floor in the derrick  102  where rig floor personnel can latch on with an elevator and raise the pipe to a vertical position. 
     The derrick structures of these large drilling rigs require high capital and operating cost, including significant transport logistics. The rigs may be assembled on site and must be capable of withstanding rotary torques and other loads. 
     For operations of less demand, and that do not require larger torques, a reduced-size and portable workover rig may be used.  FIG.  1 B  shows a simplified view of a conventional drilling operation  100   a  that utilizes a workover rig  121 . Such an operation may be useful where shallower depths are drilled or the formation allows easier drilling. 
     The rig  121  may have mast  101   a  suitable for erecting onsite, thus avoiding the need for a large derrick that requires complete assembly. The mast  101   a  may have a first portion  102   a  and a second portion  102   b  that telescope together for easy transport. 
     The rig  121  is positioned, and the mast  101   a  is raised proximate the well/wellhead  122 . Rotation is typically accomplished using a driver, namely, a power swivel  110 , thus eliminating the need for the kelly and associated equipment. Tensioned torque reaction cables are used to react torque loads generated by the power swivel  110 , which is typically supported on a hook or travelling block  116 . Resultant torque from operation is reacted through an arm of the power swivel  110  coupled with a wire line or torque cable that is secured to the rig (not viewable here) In this manner, the power swivel  110  can apply torque to a tubular (e.g.,  103 ,  FIG.  1 A ) while moving up or down the rig with the pipestring. 
     Torques generated by the power swivel  110  are known to be limited, given the limited size of the rig  121 . For example, a torque limit of 2500 ft-lbs (3390 joules) is typical. Even with these torque limitations, there are unwanted safety risks, hardware damage risks, or other problems. To accommodate torque management, the power swivel  110  is configured with a torque arm housing, as well as a telescoping rod. The end of the rod is coupled with a guide cable, such as via a shackle or hoop (with the cable passing therethrough. 
     The drawbacks of this configuration are numerous. For example, after continuous use the friction between the shackle and (wire) cable can suffer integral damage, thus causing them to break, resulting in chance of injury to personnel and/or damage to equipment. Moreover, when torque is applied on the shackle, this results in a point load against the cable, which then increases stresses resulting in eventual material failure/breaking. On top of the rig floor, the shackle bolt needs to be removed to put over the wire. This results in a safety hazard if the bolt or shackle are dropped. 
     For a more elegant solution, torque arm rollers may be used.  FIG.  1 C  shows a conventional torque arm roller assembly  124  that may be coupled with a telescoping rod  123  movable within torque arm housing  122 . The torque arm housing  122  may extend outward (such as laterally) from the power swivel  110 . As the power swivel  110  moves up/down to accommodate position of the pipestring, the torque arm roller assembly  124  follows along the torque guide cable  117  (via sheaves or rollers  118 ). 
     The use of the torque arm roller assembly  124 , while useful for managing torque reaction, is cumbersome. Every time the mast  101   a  is erected, the roller assembly  124  must be assembled and disassembled in order to receive the cable  117  therein (or if lowered, remove the cable  117  therefrom). The use of a track instead of a cable is also problematic, as the presence of a telescoping mast  101   a  is problematic at best. 
     A need exits for torque management that addresses these deficiencies and concerns. 
     The ability to increase efficiency and save operational time and expense while increasing safety leads to considerable competition in the marketplace. Achieving any ability to save time, or ultimately cost, while increasing safety leads to an immediate competitive advantage. Thus, there is a need in the art for a rig assembly useful for torque management of a power swivel that may save time and increase safety.

       FIGS.  2 A- 2 I  together show a mobile unit  201  for use in an industrial operation or system  200 . The operation or system  200  may be for drilling. While it need not be exactly the same, the unit  201  may be assembled, run, and operated as described herein and in other embodiments, and as otherwise understood to one of skill in the art. Similarities may not be discussed for the sake of brevity. Components of the unit  201  may be arranged by, disposed on, or otherwise coupled with a trailer or support frame  213 , and as otherwise made evident. 
     Associated or auxiliary equipment including automation, controllers, piping, hosing, valves, wiring, nozzles, pumps, gearing, tanks, etc. may be shown only in part, or may not be shown or described, as one of skill in the art would have an understanding of coupling the components of the unit  201  for operation thereof of the system  200 . For example, a pump (with engine) may be in fluid communication with one or more sources, such as a fluid tank, with the unit  201  (or its components) being in fluid communication with a discharge of the pump (such as via a manifold, piping, tubing, etc.). All components of the unit  201  requiring power or automation may be provided with wiring, tubing, piping, hydraulics, etc. in order to be operable therefore. 
     The unit  201  may be used with and be part of the system  200 , such that the system  200  may include a mast or comparable structure configured with suitable components to rotate a drill string  204 . The drill string may be rotated with a power swivel type mechanism  210  (with associated elevator, drive frame, drawworks, travel block  243 , etc.). 
     The mobile unit  201  may be configured with the frame  213  being configured or fitted with various components attached thereon, including for transport. The frame  213  may be part of a trailer or a skid  201   a  configured to be towed or otherwise transported to a site for use.

The mast  202  may have a second position  242   a , which may be erected and ready for operation for the system  200 . As the mast  202  may be multi-piece, the mast  202  may have a first mast portion  202   a  and a second mast portion  202   b . The first and second portions  202  a, b may be coupled together, such as telescopingly or slidingly. For height and operational concerns, there may only the two telescoping portions  202  a, b; however, it is within the scope of the disclosure that additional portions may be used. As such, there may be another mast position that includes the mast  202  raised, and the second portion  202   b  fully extended from the first portion  202   a . 
     The mast  202  may be movingly coupled with the platform  213 , such as at a connection point(s)  240 . Just the same, the mast  202  may be assembled onsite, and is not otherwise limited to any size or configuration. Also, although shown as land-based, the associated operation of the system  200  could be offshore, such that the mobile unit  201  could be on or part of a floating vessel. While reference may be made to ‘drilling’, the working operation or system  200  is not meant to be limited, as there are a number of instances and operations where the unit  201  may be used. 
     The unit  201  may be operated or otherwise used in a manner to provide, control, facilitate, etc. handling and transport of one or more components. In embodiments, the unit  201  may provide delivery of either a tubular  203  and/or a power swivel  210  to a rig or derrick floor  241 . The unit  201  may have the power swivel  210  and associated components disposed thereon, including for times of storage and/or transport. Associated or auxiliary components may include a hose reel, a hydraulic fluid tank, a pump and engine, and the like. Although not shown here, the unit  201  may have an operator station, which may allow rig personnel  207  to control the power swivel  210  and overall rig or system operation  200 . 
     One of skill would appreciate that some or all operations associated with operating the unit  201 , as well as operation of the power swivel  210  (including while on the rig  202 ), may be accomplished by personnel  207  via the operator station and/or manually. While not shown in detail, there may be powered systems (such as cable winch or hydraulic pistons) for raising the mast  202  from the first position  242   a  to the second position  242   b . The mast  202  may also be powered for telescoping the portions  202  a, b (extending or retracting). 
     When presented to the operator  207  (or rig floor  241 ), the tubular  203  may be engaged (e.g., threadingly) by the power swivel  210 , lifted, and then moved to a vertical position for engagement (making up) with another tubular. The tubular  203  and/or power swivel  210  may be presented or otherwise positioned at an angle. Advantageously, the tubular  203  may be presented from any side of the floor  241 , such as from the first side, the second side, and/or the front. 
     The power swivel  210  may have a stem  234  for threadably engaging the tubular  203 . The traveling block  243  of the mast  202  may be raised or lowered with the power swivel  210 , as indicated by arrows A (via pulleys, cables, etc.). Although the mast  202  is shown only in part here, one of skill would appreciate that the mast  202  may extend upward by tens or hundreds of feet. One of skill would also appreciate that although only showed in partial detail here, the rig floor  241  may be part of a support structure  271 , which may include legs, trusses, scaffolding, and the like. The rig floor  241  may be movable. Instead of or in addition to, the rig floor  241  may be coupled with and supported by (such as in a cantilevered fashion) the mast  202 . 
     The operation of the system  200  may include the use of a track handling assembly or device  224 . The track handling device  224  may be a combination of movable linking members configured in a manner whereby the device  224  may be in a first device position  224   a  akin to storage or retraction. This may coincide with the first position  242   a  of the mast  202 . However, the position of the track handling device  224  and the mast may be mutually exclusive. As such, the mast  202  may be moved to its second position  242   b , while the device  224  remains in the first device position  224   a . To accommodate movement of the device  224 , there may be respective pivot points  240   a  where the device  224  is movingly coupled with the frame  213 . 
       FIG.  2 B  shows the track handling device  224  and the mast  202  in their respective first positions. In this position, a track  226  lies prone with a slider  227  movingly engaged therewith. The track  226  may be coupled with a boot  225  of the device  224 . The boot  225  and the track  226  may be coupled together at coupling point  229 , such as via nut and bolt or the like. 
       FIG.  2 C  shows an intermediate position of the mast  202 , where the mast  202  may be moving to or from the first mast position  242   a . The intermediate position may be contemplated as a range of positions other than the first mast position  242   a , and whereby mast legs  230  are not engaged with respective mast support legs  244   a  (of the mast support frame  244 ). During this transition, the track handling device  224  may remain in the first device position  224   a . 
       FIGS.  2 D and  2 E  together show the mast  202  now moved to its second position  242   b , and with the track handling device  224  moving from its first position ( 224   a ,  FIG.  2 D ) to its second position ( 224   b ,  FIG.  2 E ). The second position  224   b  may coincide with the track handling device  224  being moved over a wellhead (or BOP, etc.)  233 . As shown, the device  224  may have a main arm  232  extended outward (compare 2D with 2E). The main arm  232   may have an end configured with the boot  225 , such that as the main arm  232  is extended out, by being coupled therewith, the track  226  may also be extended outward. 
     To facilitate movement of the device  224 , the operator  207  may couple the device  224  with the power swivel  210 . For example, the slider  227  may be configured or coupled with a power swivel coupler  231 , which may then be coupled with the power swivel  210 . The operator  207  may then grab and move the power swivel, which resultantly moves the device  224 . 
       FIGS.  2 E and  2 F  illustrate the tubular  203  may be fed and coupled with the power swivel  210  from different directions. There are a number of reasons why it may be beneficial to accommodate feeding and connecting tubulars from different sides of the rig floor  241 , and advantageously the track handling device  224  may accommodate any such necessity. For example, the swivel coupler  231  may be interchangeable with other coupler configurations and orientations. In addition, or the alternative, the slider  227  may be rotated (e.g., 90 degrees, 180 degrees, etc.) on the track  226 . 
       FIGS.  2 E and  2 G  illustrate that the slider  227  may be moved along the track  226  from a first or bottom position ( 227   a ,  FIG.  2 E ) to another position ( 227   b ,  FIG.  2 G ). As the slider  227  may be freely movable along the track  226 , the power swivel  210  may be raised and lowered accordingly (see Arrow A). At the suitable height, the power swivel  210  may now be operational to rotate the drillstring  204 . 
       FIG.  2 H  illustrates the mast  202  moved to its second mast position  242   b . As one of skill would appreciate, in this position the second mast portion  202   b  has been extended out and upward of the first mast portion  202   a , such that the mast  202  may be at its fully extended height H. The slider  227  remains freely movable along the track  226 , such that the power swivel  210  may be moved to any height in order to accommodate make up and break out of the tubular(s)  203  or other desired operation. 
     One of skill would appreciate that as there may be the first mast portion  202   a  and the second mast portion  202   b , the track  226  may analogously have a first track portion  226   a  and a second track portion  226   b . The first track portion  226   a  and the second track portion  226   b  may be movingly engaged with each other, such as slidingly, telescopingly, etc. While the first track portion  226   a  may be coupled with the boot coupler (not viewable here), the second track portion  226   b  may be coupled with the mast  202  at top track coupling point  202   c . Thus, as the mast portions  202  a, b extend and retract together, so may the track portions  226  a, b. 
       FIG.  2 I  illustrates the track handling device  224  may be configured with a power swivel support rack  235 . The power swivel  210  may have one or more torque arms  235  extending therefrom suitable for engagement/disengagement with the support rack  235 . The power swivel coupler  231  may be configured for engagement with any of the torque arms  236 . The coupling between the power swivel  210  via the torque arm  235  to the coupler  231 , and via the coupler  231  to the slider  227 , and via the slider  227  to the track  226  may facilitate transfer of torque or other load from operation of the power swivel  210  to the mast  202 . 
       FIG.  2 I  further illustrates how the rig floor  241  may be configured with either or both of a tubular gap or clearance  238  (for tubular  203  to fit therethrough) and a track gap or clearance  237  (for track  226  to fit therethrough). 
     Referring now to  FIGS.  3 A,  3 B, and  3 C , a front side isometric view of a track handling device, a downward plan view of the track handling device, and a front side isometric view of a rigid frame of the track handling device, respectively, illustrative of embodiments disclosed herein, are shown. 
       FIGS.  3 A- 3 C  together show a track handling device  324  that may be used with a rig, derrick, or other comparable equipment. While referred to as a ‘drilling operation’ from time to time, embodiments herein are not limited and other applications are possible. Without limitation, the track handling device  324  may be like that of other device(s) (e.g.,  224 ) described herein, including in some respects similar/identical or in other respects different. 
     The track handling device  324  may be an assembly of multiple component(s) and subcomponent(s) features, any of which may be connected with (such as fixedly [e.g., welded or the like] or movingly) or integral to each other. To accommodate rigor and stress associated with operation of the device  324 , many or all (sub)components may be made of a durable metal, such as carbon steel. That said, some parts of the device  324  may be rubber, plastic, or other suitable material. The device  324  may be configured to withstand loads (including significant loads) associated with operation of a power swivel ( 210 ) or other rotational driver. 
     The track handling device  324  may be a combination of a static or rigid portion  324   d  coupled together with one or more movable members of a movable portion. For example, the rigid portion  324   d  may include a base frame or spreader  353  having one or more posts or arms  352 ,  358  extending therefrom. As shown here, there may be main post  352  and a support rack post  358  having a general vertical orientation as compared to the horizontal nature of the spreader  353 . 
     Either or both of the main post  352  and the support rack post  358  may be configured with a power swivel support rack feature  335   b  and  335   a , respectively. These seat-style features  335   a  and  335   b  may be useable separate or together to provide a support rack  335  for a power swivel ( 210 ). This may aid simple and convenient capability or storage and transport of the power swivel (see  FIG.  2 A ). 
     The spreader  353  may have one or legs  319  extending therefrom. The legs  319  may have a respective hinge mount  318 , suitable for coupling the device  324  with a support frame or structure ( 213 / 244 ). The hinge mounts  318  may provide the capability for the device  324  to be movingly (such as hingedly or pivotably) coupled with the support frame or structure. 
     The spreader  353  may also have one or more latch receptacles  320  extending therefrom. The latch receptacle  320  may be configured to receive a respective latch (e.g.,  221 ,  FIG.  2 C ), which may be useful to help lock and maintain the track handling device  324  in an upright position. In aspects, the track handling device  324  may be moved from a resting or prone position to the upright position, and vice versa. 
     The rigid portion  324   d  may also have one or more other support members or beams, such as a cross or diagonal member  357 . The cross member  357  may extend between the main post  352  and the support rack post  358 , including diagonally, as shown here. The rigid portion  324   d  may be coupled with a movable portion that includes one or more dynamic or moving members. For example, the device  324  may have a driver arm  351  coupled with rigid portion  324   d . The driver arm  351  may have a first or bottom driver arm portion  351   a  (movably) coupled with the rigid portion  324   d  (or spreader  353 ) at pivot or coupler point  350   d . The driver arm  351  may have a second or top driver arm portion  351   b  (movably) coupled with a main support arm  332  at pivot or coupler point  350   c . 
     The driver arm  351  may have a hollowed arm region  359  configured to accommodate upward and downward motion of the driver arm  351  with respect to the main post  352 . In this manner, the driver arm  351  and the main support arm  332  may be operable together for the device  324  to move from its first or retracted position ( 224   a ,  FIG.  2 D ) to its second or extended position ( 224   b ,  FIG.  2 E ), and vice versa. 
     In addition, there may be a follower arm  354  that may be movable. The follower arm  354  may be (movably) coupled with an upper end  332   b  of the main support arm  332 , such as at pivot or coupler point  350   a . The follower arm  354  may be (movably) coupled with an upper post portion  352   b  of the main post  352 , such as at pivot or coupler point  350   b . The arms  351 ,  354 , and  332  may then work together to provide the dynamic or movable feature of the track handling device  324 . 
     The movable portion of the track handling device  324  may accommodate the support and use of a torque track (or just track)  326 .  FIG.  3 A  shows in partial detail the track handling device  324  may include the track  326 . The track  326  is an elongated member in the tens or hundreds of feet in its length. The track  326  may be configured to handle and distribute loads/torque associated with a power swivel. The track  326  may be coupled with a boot coupler  329  extending from a first or lower arm end  332   a  of the main support arm  332 . 
     In accordance with embodiments herein, the track handling device  324  may be used with a telescoping mast ( 202 ). In a similar sense, it may be the case that the track handling device  324  may be used with a telescoping track  326 , such as shown in part in  FIG.  3 A . 
     For example, the track  326  may have a first or lower track portion  326   a . The first track portion  326   a  may have a first track dimension (e.g., width, diameter, etc.) D 1 . There may be a second track portion  326   b , which may have its respective track dimension D 2 . The first track portion  326   a  and the second track portion  326   b  may be movably coupled together, such as telescopingly. As such, the first track dimension D 1  may be larger than the respective (second) track dimension D 2 . The first track portion  326   a  may be configured in a manner for the second track portion  326   b  to extend therefrom and retract thereinto. 
     There may be a slider  327  movably engaged with the track  326 . Although not shown in detail here, the slider  327  may be configured in a manner for the slider  327  to couple with a power swivel ( 210 ). In operation of the power swivel, the swivel may be raised or lowered, and as such the slider  327  may follow along via freedom of movement on the track  326 . The slider  327  may be configured with pads or rollers that reduces or mitigates friction between the track  326  and the slider  326 . 
     Although the slider  327  may be configured for movable engagement with a given track dimension (e.g., D 1 ), the slider  327  may not be able to readily move onto and accommodate engagement with a different track dimension, such as D 2 . As such, there may be an adapter or bushing  339  movably engaged with the track  326 , and more particularly, the second track portion  326   b . The bushing  339  may be configured with pads or rollers that reduces or mitigates friction between the track  326   b  and the slider bushing  339 . 
     The slider  327  and the bushing  339  may be configured for engagement together in the event the slider  327  is moved toward the second track portion  326   b . As an example, and although not shown here, the slider  327  may have a mating feature corresponding to a respective mating feature of the bushing. Upon engagement, the mating features operate together to keep the slider  327  engaged with the bushing  339  as the power swivel is moved respectively with the second track portion  326   b . 
     The respective mating feature of the bushing  339  may be configured to release from the mating feature of the slider  337  in the event the power swivel is moved back toward and respectively with the first track portion  326   a . For example, the first track portion  326   a  may be configured with a profile or feature that prompts disengagement of the mated slider/bushing upon contact therewith. 
     The moving portion of the device  324  may have additional support from one or more turnbuckles  355   a ,  355   b . The turnbuckles  355   a ,  355   b  may be coupled between the main support arm  332  and the spreader  353 . As such, each of the support arm  332  and the spreader  353  may be configured with features or fittings for the respective turnbuckle  355   a ,  355   b  to couple therewith. 
     Referring briefly to  FIG.  4   , a longitudinal side view of a first turnbuckle and a second turnbuckle, illustrative of embodiments disclosed herein, is shown.  FIG.  4    shows a first turnbuckle  455   a  and a second turnbuckle  455   b  that may be used with a track handling device of the present disclosure. The first turnbuckle  455   a  may be configured with a first turnbuckle length L 1 , and the second turnbuckle  455   b  may be configured with a second turnbuckle length L 2 . Although not limited, the first turnbuckle length L 1  may be longer than the second turnbuckle length L 2 . 
     Referring again to  FIGS.  3 A- 3 C , the use of turnbuckles  355   a  and  355   b  with respective offset lengths may accommodate an offsetting of the main post  352  from a centerline of the spreader  353 . As the post  352  is offset so may be the moving arms  351 ,  354 ,  332 . This configuration may provide clearance for the power swivel to move back and forth from the power swivel support rack  335 . 
     Referring now to  FIGS.  5 A,  5 B,  5 C, and  5 D , a side view of a power swivel in a first swivel orientation coupled with a slider, a power swivel in a second swivel orientation coupled with a slider, a partial side cross-sectional view of a power swivel torque arm engaged with a slider lug, and an isometric view of an alternate slider lug, respectively, illustrative of embodiments disclosed herein, are shown. 
       FIGS.  5 A- 5 D  together show a track handling device of the present disclosure may include or be associated with a power swivel  310  coupled (via a power swivel coupler  331 ) with a track slider  327 . The coupling between the power swivel  310  and the track slider  327  may further include the power swivel  310  having one or more torque arms  336  that extend therefrom. A coupler lug  361  may be inserted through the coupler  331  and into engagement with the respective torque arm  336 . As shown here, the coupler lug  361  may have an opening or bore  361   a  for the torque arm  336  to fit therein. There may be a coupler pad or insert  363 , such as between the coupler  331  and the lug  361 , which may help accommodate discrepancies or differences between different pieces of equipment. 
     A lug pin  362  or other comparable securing device may be inserted through each of the lug  361  and the torque arm  336 , such that the lug  361  and arm  336  are held together. There may be a housing or extension  360  for which the coupler  331  may have a coupler end  331   a  inserted therein. One or more coupler pins or bolts  364  may be inserted through the extension and coupler end  331   a  for securely holding the coupler  331  therewith.  FIGS.  5 A and  5 B  show how the power swivel  310  may have a first swivel orientation  310   a , but in the event another or second orientation  310   b  may better suit operation, the coupler  331 , lug  361 , slider  327 , etc. may be reconfigured to accommodate changes in orientation (which then corresponds to different orientations for which a tubular may be fed to the power swivel  310 ). 
     Referring now to  FIGS.  6 A and  6 B , a side view of a track handling device in a first position and a side view of the track handling device in a second position, respectively, illustrative of embodiments disclosed herein, are shown. 
       FIGS.  6 A and  6 B  together show a track handling device  324  of the present disclosure. The track handling device  324  may be coupled with a mast support frame  344 . The first position  324   a  of the track handling device  324  may include a power swivel  310  stowed or engaged on a support rack  335 . The track handling device  324  may be maintained in the first position  324   a  until a mast  302  is moved to its final, secured position  342   b  shown in  FIG.  6 B . In the final position  342   b , mast legs  330  may be engaged with respective support frame legs  344   a . 
     The track handling device  324  may be movingly engaged with the mast  344 ; as the device  324  is moved upright, latches  321  may be engaged with latch points  320 , which may provide additional stability to the device  324 . When desired to return the device  324  to a prone position, the latches  321  may be disconnected from the latch points  320 . 
     Once the mast  302  may be made secure, an operator  307  may couple the power swivel  310  with a slider  327  via coupler lug  361 . The power swivel  310  may then freely be moved from the support rack  335 . As the power swivel  310  may be coupled with the track handling device  324 , this may result in the track handling device  324  being moved to the second position  324   b . 
     Of interest, the track handling device  324  may have a horizontal driver pin axis or reference line  370   a . Analogously, boot pin  372  may have a horizontal boot pin axis or reference line  370   b . As the arms  351 ,  354 ,  332  move with some amount of rotation or pivot, the track device  324  remains in a (near) straight line mechanism, as illustrated by a clearance C remaining constant (within 0.5 inches) between the first position  324   a  and the second position  324   b . 
     Referring now to  FIGS.  7 A,  7 B,  7 C,  7 D,  7 E, and  7 F , a side profile view of part of a torque track slider and bushing, a side profile view of a power swivel engaged with the slider, a side profile view of the slider engaged with the bushing, a side profile view of a bushing housing removed from the bushing, a side profile view of the slider and bushing moving together over a track with reduced dimension, and a side profile view of a bushing body, respectively, illustrative of embodiments disclosed herein, are shown. 
       FIGS.  7 A- 7 F  together show the operation or system ( 200 ) may include a track  326  having one more track portions with varied dimension (e.g., width). As shown, there may be a first or lower track portion  326   a  engaged with a second track portion  326   b . The engagement between the portions  326  a, b may be, for example, telescopingly. Thus, the second track portion  326   b  may extend out from and retract into the first track portion  326   a . 
     In the extended position, akin to an operational configuration of the system, a power swivel  310  may be able to be raised and lowered along either of the track portions  326   a  and  326   b . The power swivel  310  may be coupled with a movable slider  327  that is engaged with the track portion  326   a , and thus the slider  327  may be configured to accommodate the dimension or shape of the first track portion  326   a . 
     As the slider  327  approaches a transition  380  of where the second track portion  326   b  is positioned, a top slider end  327   a  may come within proximity to a bushing or adapter  339 . Just as the slider  327  may be movable along the first track portion  326   a , the bushing  339  may be configured to accommodate the dimension or shape of the second track portion  326   b . 
     The bushing  339  may be configured for rapid engagement and release with the slider  327  so that during operation there is no noticeable lag when the power swivel  310  needs to traverse the transition  380  upwardly or downwardly.  FIGS.  7 C and  7 D  in particular show the slider  327  and the bushing  339  in a latched engaged position  373  ( FIG.  7 D  has the bushing housing  339   a  removed in order to provide a clearer view of engagement). 
     Once engaged, the slider  327  and the bushing  339  may move collectively together (with power swivel  310 ) along the second track portion  326   b . To aid movement between the bushing  339  and the second track portion  326   b , a main bushing body  375  may be configured with one or more rollers or pads  376 . 
     To maintain engagement between the bushing  339  and the slider  327 , there may be a latch mechanism  377 . The latch mechanism  377  may be configured to activate upon engagement by the slider  327  with the bushing, and resultantly latch and hold the bushing  339  and the slider  327  together. In addition, there may be one or more bushing protrusions  381  configured to mate with a respective slider receptacle (see  382 ,  FIG.  5 B ). 
     The latch mechanism  377  may include an elongated latch member or piston  379  configured to move and cause release or unlock of the latch mechanism  377 , thus resulting in latch disengagement between the slider  327  and the bushing  339 . The latch piston  379  may be moved when the engaged slider/bushing come back into proximity with the first track portion  326   a . At this point, a track profile or shoulder  378  comes into contact with the piston  379 , and resultantly causes movement thereof. Upon release, the slider  327  is now free to move again on the first track portion  326   a . 
     Referring now to  FIGS.  8 A,  8 B,  8 C,  8 D, and  8 E , a side profile view of a slider proximate to a bushing, a side profile view of the slider and bushing in a latched engagement, a partial side view of the latched engagement of the slider and bushing, a partial side view of an unlatched engagement of the slider and bushing, and an isometric component view of a latch mechanism, respectively, illustrative of embodiments disclosed herein, are shown. 
       FIGS.  8 A- 8 E  together show in greater detail the events that occur when a slider  327  comes into proximity with the bushing  339 . As mentioned, when a power swivel  310  is coupled with the slider  327  (via coupler  331 ), the power swivel  310  and slider  327  may be freely movable along a track ( 326 ) having a first track portion  326   a  and a second track portion  326   b . 
     As the slider  327  comes into contact with the bushing  339 , a slider shoulder  390  of a top slider end  327   a  may abut against a bushing shoulder  389  of bushing housing  339   a . This then results in the bushing  339  lifted from its resting position. In its resting position as generally shown in  FIG.  8 A , a latch mechanism  377  of the bushing  339  may have a latch piston or rod  379  engaged with a track profile  378  that results in an urging or bias against a bias member  399 . The bias member  399  may be stored within a chamber or housing  388  and held in situ via cover or top  395 .  FIG.  8 A  (and  FIG.  8 D ) shows the compressed position  399   a  of the bias member  399 . 
     However, as the slider  327  raises the bushing  339 , the bias member  399  may move to an expanded or extended position  399   b  in order to urge a cam rod  394  downward, which resultantly shifts or articulates cam links  398  sufficiently enough so that a cam link lip  397  may extend outward into a slider window or opening  396 .  FIG.  8 B  in particular shows the cam link lip  397  engaged with a slider window shoulder  327   b , and thus the slider  327  and the bushing now in the latched position  373 . 
     Once the power swivel  310  moves back down to the first track portion  326   a  and away from the second track portion  326   b , the latch piston  379  may once again come into contact with the track profile  378 . This may then result in raising the piston  379  and (re)compressing the bias member  399  to its compressed position  399   a . The cam rod  394  may then be retracted, which lets the cam links  395  shift, and unlatches the lip  397 . The bushing  339  and the slider  327  are then once again in an unlatched position  373   a , and the slider  327  and power swivel  310  may continue unabated. The bushing  339  may rest in this position until once again engaged by the slider  327 . 
     Advantages 
     Embodiments of the disclosure pertain to a track handling device that may be useable for any telescoping mast. The device may include its own telescoping track that scopes up and down with a mast, with no other rig-down requirement needed. The track may lay prone with the mast, with no other rig-down required. 
     The track handling device may advantageously include a power swivel coupled therewith. The power swivel may be repositioned toward any V-door location. The power swivel is not limited to any particular size, the and track handling device may accommodate a vast range of sizes. The power swivel may be stowed or parked on a support rack coupled with the track handling device. 
     The track handling device may eliminate or mitigate torque or other forces (incurred via operation of the power swivel) passing into the mast, and instead transfer to the mobile unit. 
     The track may hang from or couple with a crown of the mast. 
     In aspects, the track may have portions supported by a link that may beneficially direct some/all torque to the mast crown beams. The portions may be slidingly coupled by plastic wear pads installed in a retention sequence by bolting only the last wear pad. The track handling device may support the Lower track beam being mounted/pinned on clevis lugs welded to several mast c-frame horizontal beams. The device may reacts torque through its linkage into the clevis lug mounts welded to the mast. The device may have a unique geometry allowing infinite, level-adjustment of arm extension or retraction. The moving portion or arm may be contemplated as an ‘equilibrating linkage mechanism’, which may prevent falling under its own weight as does a simple parallelogram 4-bar linkage. 
     Heights upwards of forty feet or more are possible for the mast. 
     The slider may be rotationally coupled to a driver, such as a power swivel or top drive, via a bail pin. The slider may include rollers, bearings, pads, or the like that engage the track. The slider may have a pin or tube configured to capture/secure the bail pin, but yet allow rotational coupling of the slider to the swivel. The pin/tube may be removable and rotates within the slider body (or an extension thereof). The pin/tube may be replaced to match different fits required for other bail pin sizes. The slider may use (welded) wear pad retainer plates with an interlocking style of wear pad mounting within said dolly which require only bolting one (last) wear pad. There may be a bushing with (welded) wear pad retainer plates with an interlocking style of wear pad mounting within said dolly which require only bolting one (last) wear pad. 
     Embodiments of the present disclosure save time. Even a small savings in drilling or servicing time of individual wells results in an enormous savings on an annual basis.
