This Application claims the benefit of U.S. Provisional Application No. 61/231,912, filed Aug. 6, 2009, all of which is incorporated herein by this reference.


BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to fluid transporting vehicles, and more particularly, to tanker vehicles figured to transport liquids including liquid sludge.
Liquid transporting vehicles such as tank trucks are previously known and such tank trucks typically are hinged at the back end with the front end of the tank being driven upward by a hydraulic cylinder to tip the front end of the tank up to decant the contents of the tank. Fluids typically are drawn into the tank by a vacuum apparatus. Because of bridge and road limits, such tank trucks typically are limited to a maximum capacity of 2,500 gallons at 10 pounds per gall on of capacity. Cleaning of the tanks after decanting of the fluid is typically done by manpower, for example an individual getting into the tank to scrub and clean the tank, or the tank can be cleaned by a mechanical vibrator.
The limitations of weight, in order to comply with various road and bridge restrictions, and the additional cost involved in cleaning the tank by the use of manpower or mechanical vibrators make the transportation of liquids and liquid sludge in a typical tanker vehicle expensive and not efficient. The extendable mobile fluid carrying apparatus disclosed herein overcomes the problems and limitations of the prior art by providing a vehicle that is agile, having a high cubic feet per minute blower (high-CFM) vacuum truck that is capable of hauling 45,000 pounds of payload capacity and does not violate bridge and road weight restrictions.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Referring to the Figures, there is illustrated an exemplary embodiment of an extendable mobile fluid carrying apparatus 20 includes a tractor 24 having a cab configured for driving and maneuvering the apparatus on-road and off-road conditions. Coupled to the tractor 24 is a trailer apparatus 34 which includes a first frame 36 and a slidable second frame 42. The slidable subframe allows the trailer length to be reduced approximately 32 feet when maneuvering in tight constraints at a worksite but configured to allow the sliding subframe to extend away from the first frame 36 automatically as the first frame 36 is moved forward by the tractor 24. With the sliding subframe extended, the trailer length is extended to approximately 43 feet thereby allowing the weight distribution over a longer wheel base to comply with applicable bridge and road restrictions.
A vacuum tank, approximately 82 inches in diameter and approximately 20 feet long, has a typical capacity of 5,000 gallons of fluid. The vacuum tank or fluid container 50 has a full opening swing up rear door 58 that can be opened and lowered either by the operation of gravity or by actuation by a dual action hydraulic pump and cylinder 60. The swing door 58 is coupled to the fluid container 50 with a door hinge 59. A plurality of lock devices are positioned along the perimeter of the door to fluidly seal the door 58 to the container 50. The fluid container 50 or vacuum tank is also pivotally coupled with pivot devices 51 to the first frame 36 and can be raised to at least as high as 75°, relative to the first frame 36, for purposes of off loading, by gravity, the contents of the fluid tank 50. The contents of the fluid tank 50 typically is a high viscosity sludge, vacuumed by suction, at an industrial site and hauled away for further processing. To off load the sludge, the rear swing door 58 is unlocked and opens as the fluid container 50 tank is raised. Because of the height of the tank front end 38, the sludge and fluid slides out of the tank and typically does not require cleaning by means of a mechanical vibrator or the need for a person to enter the tank to shovel or scrape the material from the tank for cleaning purposes. The exemplary embodiment of the extendable mobile fluid carrying apparatus 20 includes a high-CFM blower apparatus 80 which draws a suction through appropriate plumbing 92, vacuum coupler 86, accumulators, filters 82, and cyclone apparatus 84 to draw a vacuum through the fluid tank 50 and provide suction for gathering fluids, materials in the fluid, and liquid sludge at a worksite into the fluid tank. An example of a blower system 80 is model 616DVJ manufactured by Roots with Stoddard silencers model No. 73A625 and 73A558.
The tractor 24 typically is a Class 8 tractor such as manufactured by Peterbilt, however any appropriate tractor 24 having a sufficient prime mover 28, for example an internal combustion engine, preferably a diesel engine, can be used with the extendable mobile fluid carrying apparatus. The tractor 24 can also be provided with a power take-off (PTO) mechanism 32 coupled to the prime mover 28 with the power take-off mechanism coupled to the blower 80 to operate the blower 80 for generating a vacuum. Appropriate gear trains, for example a transmission, couples the PTO to the prime mover and the PTO to the blower.
The tractor 24 includes a support structure 26 configured to support a cab, the prime mover 28, and the power take-off mechanism 32. In one embodiment, the support structure 26 also supports the high-CFM blower 80 and related equipment. The support structure 26 also includes a steerable wheel set 30 controllable from the cab of the tractor 24. The support structure 26 also includes at least one additional wheel set 46, for example a tandem dual axle wheel set. The support structure 26 also includes a fifth wheel configured to couple to the trailer 34.
The fluid container 50 can be configured as a tube having a circular interior cross-section 56 and includes a full opening, swing door 58 pivotally coupled to the tube at the closable orifice 54. The door 58 is coupled to the container 50 with a suitable hinge 59 and is configured to move from a closed position 68 to an open position 70 (See FIGS. 10, 15, and 16) in order to decant any fluid, sludge or other material contained in the fluid container 50.
An exemplary embodiment of the extendable mobile fluid carrying apparatus 20 provides a door opening movement facilitated by one of gravity and a hydraulic cylinder 60.
The swing door 58 typically defines a plurality of closable ports 62 positioned proximate the lower edge of the swing door 58 when the door is in a closed position 68. (See FIG. 16) As illustrated in FIGS. 15 and 16, there are three closable ports 62. The middle port can be used to decant fluid in the fluid container 50 without opening the swing door 58.
The closable ports 62 on each side of the middle port are configured to couple to hoses for drawing waste material into the fluid container 50 during a vacuum operation. Such closable ports 62 are coupled to interior channels 64. (See FIGS. 11 and 12) In operation as waste material enters the fluid container 50 through one or both of such closable ports 62, the waste material passes up through an interior channel 64 and exits into the fluid container 50. The material typically includes fluid, solid matter, and air. The fluid and solid matter drops to the bottom of the fluid tank 50 and the air, as drawn by the high-CFM blower 80, moves through the fluid container 50 to the blower plumbing 92, filter 82, and cyclone 84 and exits to atmosphere. The extendable mobile fluid carrying apparatus 20 can also include a baghouse and silencer (Muffler) mounted on the support structure 26 or the trailer 34, as determined by the user.
A further exemplary embodiment of the apparatus 20 provides a tractor 24 which includes a power take-off mechanism 32 coupled to the blower 80. The prime mover 28 transfers power to the power-take-off mechanism 32 which in turn operates the blower 80 to draw the vacuum through the fluid container 50.
The extendable mobile fluid carrying apparatus 20 can include a second wheel set 48 coupled to the second frame 42 with at least one of the wheel sets 46 being retractable.
In operation, the extendable mobile fluid carrying apparatus 20, with the fluid container 50 empty, is transported to a work site with the second frame 42 positioned substantially completely under the first frame 36. (See FIG. 2) Through appropriate plumbing, liquid and/or liquid sludge is pumped from a work site depository into the fluid container 50 by a vacuum drawn through the fluid container 50 by a high capacity blower. A typical blower operation provides 3,800 cubic feet per minute of air movement through the system. Material being sucked up through the plumbing is deposited in the fluid container 50 with the air continuing to move through interior channels 64, one or more filters 82 and a cyclone apparatus 84 before exhausting to the atmosphere. It is anticipated that a full 5,000 gallon tank capacity, weighing approximately 45,000 pounds, can be sucked up from the worksite depository in approximately 20-30 minutes, which is an improvement over the prior art.
The extendable mobile fluid carrying apparatus 20, when it completes its pumping procedure at a worksite, can move to a second or subsequent worksite to remove waste material from that second site if there is sufficient capacity in the fluid container 50 after the first worksite operation. A limiting factor of the weight capacity of the fluid container 50 is governed by the bridge and road weight restriction requirements along a selected travel route. In a typical operation, while maneuvering at a worksite, the second frame 42 is slidingly positioned under the first frame 36 to shorten the overall length of the tractor 24 and tanker trailer 34 combination. At such time as the apparatus 20 is to move on the public highways, the second frame 42 is automatically extended to the rear of the first frame 36 by the tractor 24 pulling the first frame 36 forward thereby distributing the weight of the tanker container 50 and its contents over a longer wheel base during the trip to the site for decanting of material from the fluid container 50. The second frame 42 is also configured to support a retractable wheel set 46. The retractable wheel set 46, also referred to as a lift axle, is selectively lowered to contact the road or ground surface to facilitate axle weight distribution of the load in the fluid container 50.
A frame lock 44 is coupled to the second frame 42 and configured to engage locking orifices defined in the first frame 36. The locking orifices are positioned to lock the first and second frames 36, 42 in the retracted, nested position and in the extended position.
In an exemplary embodiment of the extendable mobile fluid carrying apparatus 20, the closed length, as measured from the front bumper to the back bumper of the subframe, is approximately 511⁄2 feet. In its extended position, the apparatus, as measured from the front bumper to the back bumper of the subframe, is approximately 611⁄2 feet.
The extendable mobile fluid carrying apparatus 20 is configured to lift the front closed end 52 (end closest to the tractor 24) of the fluid container 50 to an angle 78 between 45° and 80° relative to the first frame 36. Such high tilt extent of the fluid container 50, such as a tank, facilitates decanting of material such as sludge, typically which has a high viscosity, without requiring mechanical vibration or requiring personnel to enter the fluid container 50 to clean the tank. With the fluid container 50 at such a high angle, gravity alone will pull the high viscosity material, such as sludge and liquid, from the tank into an appropriate disposal container for further processing.
A vacuum coupler 86 is disposed on the first frame 36 to engage blower plumbing coupled to the fluid container 50 as the fluid container is lowered to its travel configuration. An exemplary embodiment of the vacuum coupler 86 is illustrated in FIGS. 7 and 8. The female portion (FIG. 8) includes a flexible collar, for example rubber, that will fluidly seal with the male portion, (FIG. 7) during a vacuum operation. The vacuum coupler 86 will disengage as the fluid container 50 is raised to discharge the contents of the container.
The first frame 36, second frame 42, and the fluid container 50 are composed of material consisting of steel, aluminum, and a combination of steel and aluminum. Such material compositions provide for a lighter vehicle 22 which together with the extendable wheel base allows for a higher fluid tank capacity and still maintaining appropriate weight distribution to comply with applicable bridge and road weight restrictions.
The apparatus 20 of the present invention must also be of construction which is both durable and long lasting, and it should also require little or no maintenance to be provided by the user throughout its operating lifetime. In order to enhance the market appeal of the apparatus of the present invention, it should also be of inexpensive construction to thereby afford it the broadest possible market. Finally, it is also an objective that all of the aforesaid advantages and objectives be achieved without incurring any substantial relative disadvantage.
The extendable mobile fluid carrying apparatus is configured with appropriate light weight materials suitable for the intended purposes such as steel and/or aluminum or some combination of steel and aluminum. The extendable mobile fluid carrying apparatus provides excellent maneuverability in tight customer locations and provides maximum capacity of as much as 45,000 pounds of payload, which coupled with the tear weight of the trailer 34 and tractor 24, meets the typical bridge and road restriction requirements of 80,000 pounds. The extendable mobile fluid carrying apparatus typically is also provided with hose which are retained in side mounted hose troughs in either side of the fluid container 50 and other appropriate hydraulic piping 88 to operate the various hydraulic cylinders 60 associated with the apparatus as well as appropriate pneumatic plumbing 90 and electrical conductors. Appropriate control stations to operate the apparatus 20 are positioned on the trailer 34 and the cab of the tractor 24. (See FIG. 5) It is also contemplated that the fluid container 50 is detachable from the first frame 36 to maximize its use with the different attachments, maintenance and other appropriate procedures.
For purposes of this disclosure, the term “coupled” means the mechanical joining of two components directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature. Such joining may be achieved with the two components and any additional intermediate members being integrally formed as a single unitary body with one another or the two components and any such additional member being attached to one another. Such adjoining may be permanent in nature or alternatively be removable or releasable in nature.
The apparatus of the extendable mobile fluid carrying apparatus 20 is of a construction which is both durable and long lasting, and which will require little or no maintenance to be provided by the user throughout its operating lifetime. The extendable mobile fluid carrying apparatus is also of inexpensive construction to enhance its market appeal and to thereby afford it the broadest possible market. Finally, all of the aforesaid advantages and objectives are achieved without incurring any substantial relative disadvantage.
