Abstract

An apparatus for servicing pipes includes a pipe holder having a frame configured to support the pipe and a movement assembly coupled to the frame and configured to rotate the pipe about a longitudinal axis of the pipe, and a first pipe servicing tool disposed proximate to an end of the pipe holder, where the first pipe servicing tool is configured to operably engage an end of the pipe when the pipe is rotated by the movement assembly.

First claim

What is claimed is:

1. An apparatus for servicing pipes, comprising:
a pipe holder comprising:
a frame configured to support the pipe; and
a movement assembly coupled to the frame and configured to rotate the pipe about a longitudinal axis of the pipe;

a first pipe servicing tool comprising a container disposed proximate to an end of the pipe holder, wherein the first pipe servicing tool is configured to operably engage an end of the pipe with the end of the pipe received within a chamber of the container when the pipe is rotated by the movement assembly;
a first actuator coupled to the pipe holder and configured to selectively move the pipe holder between a horizontal position and an inclined position, and hold the pipe holder in the inclined position as the first pipe servicing tool operably engages the end of the pipe with the end of the pipe received within the chamber of the container; and
a second actuator coupled to the pipe holder and configured to selectively move the pipe along a longitudinal axis of the pipe into operable engagement with the first pipe servicing tool.

2. The apparatus of claim 1 , wherein the first pipe servicing tool comprises a cleaning tool configured to deliver a cleaning fluid to an end of the pipe.

3. The apparatus of claim 2 , wherein the cleaning tool comprises:
a nozzle coupled to an end of a retractable arm, wherein the nozzle is configured to apply a fluid to a surface of the pipe; and
a third actuator coupled to the arm and configured to extend and retract the arm.

4. The apparatus of claim 1 , wherein the first pipe servicing tool comprises a lubrication tool configured to deliver lubricant to an end of the pipe.

5. The apparatus of claim 1 , wherein the first pipe servicing tool comprises a conductivity tester configured to test the conductivity of a conductor of the pipe.

6. The apparatus of claim 5 , wherein the conductivity tester comprises:
a third actuator coupled to a retractable shaft and configured to extend and retract the shaft;
a conductor coupled to an end of the shaft and configured to engage a conductor of the pipe; and
a shield configured to protect the conductivity tester from a collision with the pipe.

7. The apparatus of claim 6 , wherein the shield is rotatable between a first position and a second position, wherein in the first position the shield is arranged to contact the pipe and wherein in the second position the shield is arranged to allow the conductor to engage the pipe.

8. The apparatus of claim 1 , wherein the first pipe servicing tool comprises a combination tool configured to lubricate the pipe and test the conductivity of a conductor of the pipe.

9. The apparatus of claim 8 , wherein the combination tool comprises:
a rotary actuator coupled to a first end of a shaft, wherein the rotary actuator is configured to rotate the shaft;
a conductor coupled to a second end of the shaft, wherein the conductor is configured to contact a conductor of the pipe; and
an electrical lead connected to the annular conductor and extending through the conduit of the shaft.

10. The apparatus of claim 1 further comprising a second pipe servicing tool disposed proximal to the opposite end of the pipe from the first pipe servicing tool.

11. The apparatus of claim 10 , wherein the second pipe servicing tool is selected from the group consisting of a cleaning tool, a lubrication tool and a combination tool.

12. An apparatus for servicing pipes, comprising:
a pipe holder comprising:
a frame configured to support the pipe; and
a movement assembly coupled to the frame configured to manipulate the pipe;

a first pipe servicing tool disposed proximate to an end of the pipe holder and configured to operably engage an end of the pipe;
wherein the first pipe servicing tool and the movement assembly are configured to provide relative movement between the first pipe servicing tool and the pipe;
a first actuator coupled to the pipe holder and configured to selectively move the pipe holder between a horizontal position and an inclined position, and hold the pipe holder in the inclined position as the first pipe servicing tool operably engages the end of the pipe; and
a second actuator coupled to the pipe holder and configured to selectively move the pipe along a longitudinal axis of the pipe into operable engagement with the first pipe servicing tool.

13. The apparatus of claim 12 , wherein the first pipe servicing tool and the movement assembly are configured to provide relative rotational movement between the first pipe servicing tool and the pipe.

14. The apparatus of claim 12 , wherein the first pipe servicing tool and the movement assembly are configured to provide relative axial movement between the first pipe servicing tool and the pipe.

15. The apparatus of claim 14 , wherein the cleaning tool comprises:
a nozzle coupled to an end of a retractable arm, wherein the nozzle is configured to apply a fluid to a surface of the pipe; and
a third actuator coupled to the arm and configured to extend and retract the arm.

16. The apparatus of claim 12 , wherein the first pipe servicing tool comprises a conductivity tester configured to test the conductivity of a conductor of the pipe.

17. The apparatus of claim 16 , wherein the conductivity tester comprises:
a third actuator coupled to a retractable shaft and configured to extend and retract the shaft;
a conductor coupled to an end of the shaft and configured to engage a conductor of the pipe; and
a shield configured to protect the conductivity tester from a collision with the pipe.

18. The apparatus of claim 17 , wherein the shield is rotatable between a first position and a second position, wherein in the first position the shield is arranged to contact the pipe and wherein in the second position the shield is arranged to allow the conductor to engage the pipe.

19. The apparatus of claim 12 , wherein the first pipe servicing tool comprises a combination tool configured to lubricate the pipe and test the conductivity of a conductor of the pipe.

20. The apparatus of claim 19 , wherein the combination tool comprises:
a rotary actuator coupled to a first end of a shaft, wherein the rotary actuator is configured to rotate the shaft;
a conductor coupled to a second end of the shaft, wherein the conductor is configured to contact a conductor of the pipe; and
an electrical lead connected to the annular conductor and extending through the conduit of the shaft.

21. The apparatus of claim 12 , wherein the second actuator is configured to move the pipe along its longitudinal axis while the pipe holder is disposed in the inclined position.

22. A method of using the apparatus of claim 1 for servicing pipes, comprising:
supporting a pipe in one of a horizontal position and an inclined position;
moving the pipe between the horizontal and inclined positions;
disposing a pipe servicing tool proximal to an end of the pipe;
moving the pipe along a longitudinal axis of the pipe into operable engagement with the pipe servicing tool;
operating the pipe servicing tool to perform a servicing at an end of the pipe, the servicing being selected from the group consisting of delivering a fluid to the end of the pipe and testing the conductivity of a conductor of the pipe; and
holding the pipe in the inclined position as the pipe servicing tool performs the servicing at the end of the pipe.

23. The method of claim 22 , further comprising transferri
