Abstract

A system includes a trailer frame, a lifting mechanism coupled to the trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe, a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, and a hydraulic power unit configured to hydraulically power the system.

First claim

What is claimed is:

1. A system, comprising:
a trailer frame that is configured to be collapsible;
a lifting mechanism coupled to the trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe;
a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, wherein the braking mechanism is hydraulically powered by a brake hydraulic cylinder and comprises a beam pushed against the pipe in a direction of motion in line with a direction of motion of the brake hydraulic cylinder; and
a hydraulic power unit configured to hydraulically power the system.

2. The system of claim 1 , wherein the lifting mechanism comprise a hydraulic cylinder.

3. The system of claim 1 , wherein the hydraulic power unit is disposed on a skid separate from the trailer frame.

4. The system of claim 1 , wherein the trailer frame is configured to be collapsible such that at least one of a collapsed system width is less than an expanded system width, or a collapsed system length is less than an expanded system length, or a collapsed system height is less than an expanded system height.

5. The system of claim 4 , wherein a portion of the collapsible trailer frame is configured to fold in or two portions of the collapsible trailer frame are configured to move toward one another.

6. The system of claim 1 , comprising a coil containment device configured to block undesired movement of the coil of pipe.

7. The system of claim 6 , wherein the coil containment device comprises at least one of a coil containment cage, a containment flange, or a truncated containment flange.

8. The system of claim 1 , comprising wheels coupled to the trailer frame, wherein the wheels are configured to be pivotable.

9. The system of claim 1 , comprising a band cutter configured to cut bands holding the coil of pipe together during deployment of the pipe.

10. The system of claim 1 , wherein the braking mechanism comprises:
a brake arm socket; and
a brake arm coupled to the beam, wherein the brake arm is configured to fit within the brake arm socket, and wherein the brake arm is configured to extend outward from the brake arm socket via the brake hydraulic cylinder.

11. The system of claim 10 , wherein the beam comprises:
a first pipe brake tube coupled to a first brake arm, wherein the first brake arm is configured to fit within a first brake arm socket, and wherein the first pipe brake arm is configured to extend outward from the first brake arm socket a first distance; and
a second pipe brake tube coupled to a second brake arm, wherein the second brake arm is configured to fit within a second brake arm socket, wherein the first pipe brake arm is configured to extend outward from the first brake arm socket a first distance, wherein the second pipe brake arm is configured to extend outward from the second brake arm socket a second distance, and wherein the first distance is different from the second distance to accommodate different radial dimensions of the coil of pipe during deployment.

12. The system of claim 10 , wherein the braking mechanism comprises a brake stop pin configured to be inserted into the brake arm to block the beam from contacting a drum assembly of the coil of pipe.

13. A method, comprising:
providing a trailer comprising:
a trailer frame that is configured to be collapsible;
a lifting mechanism coupled to the trailer frame;
a braking mechanism that is hydraulically powered by a brake hydraulic cylinder; and
a hydraulic power unit configured to hydraulically power the trailer;

coupling a coil of pipe or a reel of pipe to the lifting mechanism;
adjusting a vertical position of the coil of pipe or the reel of pipe via the lifting mechanism;
deploying the pipe via rotation of the coil of pipe or the reel of pipe; and
applying pressure to the deploying pipe via the braking mechanism by pushing a beam against the pipe in a direction of motion in line with a direction of motion of the brake hydraulic cylinder.

14. The method of claim 13 , wherein adjusting the vertical position of the coil of pipe or the reel of pipe via the lifting mechanism comprises moving the coil of pipe or the reel of pipe at an angle with respect to the trailer frame.

15. The method of claim 13 , comprising blocking undesired movement of the coil of pipe via a coil containment cage coupled to the trailer frame.

16. The method of claim 13 , comprising blocking undesired movement of the coil of pipe via a pair of containment flanges coupled to the lifting mechanism and disposed on either side of the coil of pipe.

17. The method of claim 16 , comprising adjusting a width between the pair of containment flanges.

18. The method of claim 13 , comprising collapsing the trailer frame to reduce at least one of a width, a length, or a height of the trailer frame.

19. The method of claim 13 , comprising supporting the coil of pipe via an expandable drum assembly and coupling the expandable drum assembly to the lifting mechanism.

20. The method of claim 13 , wherein deploying the pipe comprises pulling the pipe from the trailer when the trailer is stationary or pulling the trailer.
