Abstract

An integrated fracking system may include a substructure assembly including one or more frame rails. The integrated fracking system may include a variable frequency drive (VFD) coupled to the frame rails of the substructure assembly. The integrated fracking system may include a transformer coupled to the frame rails of the substructure assembly. The integrated fracking system may include a pump subsystem. The pump subsystem may include a first frac pump, a first motor operatively coupled to the first frac pump, a second frac pump, and a second motor operatively coupled to the second frac pump. The pump subsystem may be coupled to the frame rails of the substructure assembly.

First claim

The invention claimed is:

1. An integrated fracking system comprising:
a substructure assembly including one or more frame rails, the substructure assembly having a front end and a rear end;
a pump subsystem including a first frac pump, a first motor operatively coupled to the first frac pump, a second frac pump, and a second motor operatively coupled to the second frac pump, the pump subsystem coupled to at least one frame rail;
a variable frequency drive (VFD) coupled to at least one frame rail; and
a transformer coupled to at least one frame rail;
wherein the substructure assembly includes a cable tray coupled to at least one frame rail, the cable tray positioned between the frame rails and extending from the front end of the substructure to the rear end of the substructure.

2. The integrated fracking system of claim 1 , wherein the first frac pump and first motor are offset laterally from a centerline of the substructure assembly in a first direction.

3. The integrated fracking system of claim 2 , wherein the first motor is at least partially longitudinally aligned with the second frac pump.

4. The integrated fracking system of claim 3 , wherein the fracking system has a longitudinal axis, wherein the longitudinal axis defines a forward direction and a rearward direction and wherein the first frac pump is positioned forward of the first motor and the second motor is positioned forward of the second frac pump.

5. The integrated fracking system of claim 4 , wherein the first motor is positioned at least partially abeam of the second motor.

6. The integrated fracking system of claim 4 , wherein the first frac pump is operatively coupled to the first motor by a first shaft assembly and the second frac pump is operatively coupled to the second motor by a second shaft assembly, wherein the first and second shaft assemblies are narrower than the first and second frac pumps and the first and second motors.

7. The integrated fracking system of claim 6 , wherein the first shaft assembly is aligned with the second motor and the second shaft assembly is aligned with the first motor.

8. The integrated fracking system of claim 1 , wherein the substructure assembly is part of a truck, trailer, or skid.

9. The integrated fracking system of claim 1 , wherein the substructure assembly comprises wheels.

10. The integrated fracking system of claim 1 , wherein the substructure assembly further comprises a coupler, the coupler adapted to couple the substructure assembly to a truck.

11. The integrated fracking system of claim 1 , wherein the substructure assembly further comprises a leveling system, the leveling system including at least one leg, the leg being extendable and retractable such that substructure assembly may be leveled.

12. The integrated fracking system of claim 1 , further comprising a slide-out platform subsystem, the slide-out platform subsystem including a movable platform, the movable platform slidingly coupled to the frame rails by one or more slide rails.

13. The integrated fracking system of claim 12 , wherein the movable platform is movable between a retracted position and an extended position by an actuator.

14. The integrated fracking system of claim 12 , wherein the movable platform includes one or more safety railings.

15. The integrated fracking system of claim 12 , wherein the movable platform includes a ladder assembly, the ladder assembly comprising a ladder and handrails, the handrails rigidly coupled to a floor of the movable platform, the ladder movable between a lowered position and a raised position.

16. The integrated fracking system of claim 12 , wherein the movable platform is positioned adjacent to the first frac pump and the first motor.

17. The integrated fracking system of claim 1 , wherein the VFD is coupled to the frame rails through a VFD platform.

18. The integrated fracking system of claim 1 , wherein the VFD is positioned within a VFD enclosure.

19. The integrated fracking system of claim 1 , wherein the transformer is positioned within a transformer enclosure.

20. The integrated fracking system of claim 1 , wherein the cable tray extends along a length of the substructure assembly.

21. The integrated fracking system of claim 20 wherein the cable tray houses at least one power cable that is operatively coupled to a component of the pump subsystem and wherein the cable remains operatively coupled to a component of the pump subsystem during transportation, whereby the need to reconnect each cable or line is reduced.

22. The integrated fracking system of claim 1 wherein the first and second frac pumps and first and second motors are coupled to a frac pump skid, and wherein the frac pump skid is selectively decoupleable from the substructure assembly such that the first and second frac pumps and the first and second motors may be assembled apart from substructure assembly.
