Abstract

A pipe handler trailer assists with the handling of very large and heavy pipes that are regularly raised to and lowered from an elevated surfaces. At least one wedge is removably coupled to an intermediate location within the pipe handler boom. The wedge is operative to change a longitudinal direction of the non-linear boom. The wedge has a pipe-receiving trough configured to cooperate with the pipe handler skidway and support pipes through longitudinal movement thereon. Front and rear faces are rigidly affixed to an undersurface of the wedge skidway, and are offset from parallel to each other. A pair of support hooks protrude from the wedge front face, and are designed to drop into and engage with a pair of mating slots. Once the support hooks are engaged with the slots, fasteners such as bolts and nuts are used to secure the wedge to the pipe handler boom.

Claims (46)

1. A wedge configured to removably couple to an intermediate location within a pipe handler skidway and change the longitudinal direction of the skidway, comprising:

a wedge skidway having a pipe-receiving trough configured to cooperate with said pipe handler skidway and support pipes through longitudinal movement thereon;

a rear face rigidly affixed to an undersurface of said wedge skidway;

a front face spaced from said rear face and displaced from parallel to said rear face;

at least one support hook protruding from said front face; and

at least one opening in said rear face complementary to said at least one support hook and configured to receive and engage with a support hook of like geometry to said at least one support hook;

wherein said at least one support hook further comprises a hook shaft and a hook end angularly offset from said hook shaft, thereby defining an L-shaped geometry, said hook end displaced from said front face and thereby defining an engagement gap between said front face and said hook end; and

wherein said at least one support hook further comprises a sloped taper at an end of said hook end distal to said hook shaft.

2. The wedge of claim 1 , wherein said front face is generally planar.

3. The wedge of claim 2 , wherein said rear face is generally planar.

4. The wedge of claim 1 , wherein said rear face further comprises a slot of geometry complementary to said at least one support hook, and thereby configured to receive a support hook of geometry similar to said at least one support hook therein.

5. The wedge of claim 1 , wherein said rear face further comprises at least one hole, and said front face further comprises at least one hole generally aligned with said rear face at least one hole.

6. The wedge of claim 5 , wherein said at least one rear face hole further comprises at least two rear face holes, and said at least one front face hole further comprises at least two front face holes.

7. The wedge of claim 6 , further comprising at least one side rigidly affixed to an undersurface of said wedge skidway, affixed to said front face between said at least two front face holes, and affixed to said rear face between said at least two rear face holes.

8. The wedge of claim 1 , wherein said at least one side further comprises a U-shaped geometry having a first lip affixed to said wedge skidway.

9. The wedge of claim 1 , wherein said pipe-receiving trough defines a trough first axis extending in a direction generally parallel to said pipe longitudinal movement within said pipe-receiving trough, and said pipe-receiving trough further comprises a trough bottom, trough side walls, and trough top edges distal in said trough from said trough bottom, said trough bottom extending parallel to said trough first axis by a distance greater than a distance of extent of said trough top edges parallel to said trough first axis.

10. A pipe handler having a non-linear skidway, comprising:

a supporting carriage supporting at least a first end of said skidway;

a lift arm pivotally coupled to said supporting carriage adjacent a first terminus and pivotal with respect to said supporting carriage about an axis transverse to a longitudinal axis of said skidway;

a drive operative to reposition said lift arm;

a wedge secured at an intermediate location within said pipe handler non-linear skidway and separating a first portion of said skidway from a second portion of said skidway and further configured to change a longitudinal direction of said second skidway portion from a longitudinal direction of said first skidway portion, said wedge having:

a wedge skidway having a pipe-receiving trough configured to cooperate with said pipe handler skidway and support pipes through longitudinal movement thereon;

a rear face rigidly affixed to an undersurface of said wedge skidway; and

a front face spaced from said rear face and displaced from parallel to said rear face;

a first removable fastener rigidly securing said wedge front face to a first portion of said skidway; and

a second removable fastener rigidly securing said wedge rear face to a second portion of said skidway.

11. The pipe handler of claim 10 , further comprising:

at least one support hook protruding from said front face; and

at least one opening in said rear face complementary to said at least one support hook and configured to receive and engage with a support hook of like geometry to said at least one support hook.

12. The pipe handler of claim 11 , wherein said at least one support hook further comprises a hook shaft and a hook end angularly offset from said hook shaft, thereby defining an L-shaped geometry, said hook end displaced from said front face and thereby defining an engagement gap between said front face and said hook end.

13. The pipe handler of claim 12 , wherein said at least one support hook further comprises a sloped taper at an end of said hook end distal to said hook shaft.

14. The pipe handler of claim 11 , wherein said rear face further comprises a slot of geometry complementary to said at least one support hook, and thereby configured to receive a support hook of geometry similar to said at least one support hook therein.

15. The pipe handler of claim 10 , wherein said pipe-receiving trough defines a trough first axis extending in a direction generally parallel to said pipe longitudinal movement within said pipe-receiving trough, and said pipe-receiving trough further comprises a trough bottom, trough side walls, and trough top edges distal in said trough from said trough bottom, said trough bottom extending parallel to said trough first axis by a distance greater than a distance of extent of said trough top edges parallel to said trough first axis.

16. The pipe handler of claim 15 , wherein said rear face further comprises at least one removable fastener hole, and said front face further comprises at least one removable fastener hole generally aligned with said rear face at least one removable fastener hole.

17. A wedge configured to removably couple to an intermediate location within a pipe handler skidway and change the longitudinal direction of the skidway, comprising:

a wedge skidway having a pipe-receiving trough configured to cooperate with said pipe handler skidway and support pipes through longitudinal movement thereon;

a rear face rigidly affixed to an undersurface of said wedge skidway;

a front face spaced from said rear face and displaced from parallel to said rear face;

at least one support hook protruding from said front face;

at least one opening in said rear face complementary to said at least one support hook and configured to receive and engage with a support hook of like geometry to said at least one support hook;

wherein said rear face further comprises at least one hole, and said front face further comprises at least one hole generally aligned with said rear face at least one hole;

wherein said at least one rear face hole further comprises at least two rear face holes, and said at least one front face hole further comprises at least two front face holes; and

at least one side rigidly affixed to an undersurface of said wedge skidway, affixed to said front face between said at least two front face holes, and affixed to said rear face between said at least two rear face holes.

18. The wedge of claim 17 , wherein said at least one side further comprises a U-shaped geometry having a first lip affixed to said wedge skidway.

19. The wedge of claim 17 , wherein said at least one support hook further comprises a hook shaft and a hook end angularly offset from said hook shaft, thereby defining an L-shaped geometry, said hook end displaced from said front face and thereby defining an engagement gap between said front face and said hook end.

20. The wedge of claim 19 , wherein said at least one support hook further comprises a sloped taper at an end of said hook end distal to said hook shaft.
