The telescoping tube 10 of described telescopic arm 5 is provided with fixed guide 15 with the upper arm 6 of shear arm 4 by hinge, in fixed guide 15, be fixed with tooth bar 16, motor 17 is connected with a joggle by speed reduction gear box and tooth bar 16, and slide unit 18 is by roller 19 and fixed guide 15 activity attachings; Go-cart 20 is installed on slide unit 18; Go-cart 20 is made up of pressure head 21, front push pedal 22, rear push pedal 23, and pressure head 21 is arranged on the top of go-cart 20, and front push pedal 22 and rear push pedal 23 are vertically mounted in go-cart 20 mutually.(referring to accompanying drawing 1-6).
The course of work of this novel hydraulic dynamic catwalk is as follows:
Hydraulic pressure pipe rack 2 is installed in frame 1, for putting tubing string 14, when work, first shear arm 4 and telescopic arm 5 is adjusted to the angle position suitable with hydraulic pressure pipe rack 2, loads hook 3 subsequently tubing string 14 is loaded in slide unit 18 automatically by tubing string.Between the upper arm 6 of two shear arms 4 and underarm 7, all connect by bearing pin, shear arm is installed between upper arm 6 and underarm 7 and drives oil cylinder 8, by regulating shear arm to drive the movement travel of oil cylinder 8, realize the operation to different rig floor height.
Two telescopic arms 5 are installed in frame 1, can be along corresponding bearing pin direction rotations, and drive oil cylinder 11 to control the stretching motion of telescoping tube 10 by telescopic arm; Drive the angle between the adjustable stationary pipes 9 of oil cylinder 12 and frame 1 by angular movement, and drive the distance of stretch out and draw back of oil cylinder 11 adjustable retractable pipes 10 by telescopic arm, and the gradient of slide unit 18.Between two telescopic arms 5, be fixed connection by girder steel.
Slide unit 18 is installed in fixed guide 15, can carry out stretching motion along fixed guide 15, can realize the operation of well head or rat hole position by the movement travel that regulates slide unit 18.Go-cart 20 is arranged on slide unit 18, and go-cart 20 can be moved on slide unit 18.Go-cart 20 tops are provided with a pressure head 21, can make tubing string 14 move backward under the effect of pressure head 21.In the time that go-cart 20 is carried tubing string 14 and travelled forward, pressure head 21 can lift, and relies on the base plate of go-cart 20 to promote tubing string 14 and moves forward.
Between the upper arm 6 of shear arm 4 and underarm 7, connect by bearing pin, the upper end of upper arm 6 is installed and is connected with fixed guide 15, and the lower end of underarm 7 is arranged in frame 1.Shear arm is installed between upper arm 6 and underarm 7 and drives oil cylinder 8, drive the different collapsing length of oil cylinder 8 by shear arm, can adapt to different rig floor table surface heights.
Telescopic arm 5 is made up of stationary pipes 9 and telescoping tube 10, telescopic arm is installed in stationary pipes 9 and drives oil cylinder 11, and the stationary pipes 9 of telescopic arm 5 is arranged in frame 1, and telescoping tube 10 is arranged in stationary pipes 9, and the other end of telescoping tube 10 and fixed guide 15 are hinged.The angular movement of stationary pipes 9 drives one end of oil cylinder 12 to be arranged in frame 1, and the other end is arranged in stationary pipes 9, and angular movement drives oil cylinder 12 to move, and makes the direction rotation of telescopic arm 5 along the bearing pin of stationary pipes 9.
Hydraulic pressure pipe rack 2 drives adjustable self the angle of inclination of oil cylinder 13 by comb; Adapt after angle when hydraulic pressure pipe rack 2 tilts to slide unit 18, loading hook 3 by tubing string can successfully be loaded into tubing string 14 in slide unit 18 automatically.Tubing string loads hook 3 and is installed in frame 1, is positioned at hydraulic pressure pipe rack 2 sides.
Tooth bar 16 is arranged on fixed guide 15, and motor 17 rotates by reduction box driven wheel, realizes the movement of slide unit 18 on tooth bar 16, and slide unit 18 passes through roller 19 in the interior movement of fixed guide 15.
Go-cart 20 is made up of pressure head 21, front push pedal 22, rear push pedal 23.In the time that tubing string 14 need to move forward, rear push pedal 23 first moves forward, and is adjacent to front push pedal 22, and before driving, push pedal 22 is advanced, and front push pedal 22 contacts with tubing string 14, promotes tubing string 14 and travels forward.In the time that tubing string 14 need to move backward, first drive front push pedal 22 to travel forward by rear push pedal 23, front push pedal 22 is adjacent to tubing string 14, and guarantee that pressure head 21 lifts, moved backward by rear push pedal 23, now, front push pedal 22 can not be synchronized with the movement with rear push pedal 23 under the pressure-acting of tubing string 14 again, pressure head 21 is compressed downwards, and then carry tubing string 14 and move backward.
The light compactness of this novel hydraulic dynamic catwalk structure, simple to operate, to rig floor strong adaptability, on-the-spot easy for installation, later stage maintainability is good, and work safety is stable, is well suited for drillng operation and moves tubing string use.
