Abstract

A tubular rotating system for rotating threaded tubulars is provided. The system includes a frame, a plurality of rollers coupled to the frame and configured to rotate a tubular, and a control valve coupled to the frame and configured to control a rotational speed of the rollers. The control valve controls an amount of air, fluid, or electric power supplied to the system based on tension applied to the system to thereby control the speed at which the rollers rotate.

First claim

The invention claimed is:

1. A tubular rotating system for rotating threaded tubulars, the system comprising:
a frame;
a plurality of rollers coupled to the frame and configured to rotate a tubular; and
a control valve coupled to the frame and configured to control rotational speed of the rollers based on a tension force such that the rotational speed of the rollers increases as the tension force increases.

2. The system of claim 1 , wherein the rotational speed is greater than zero when the control valve is in an off state.

3. The system of claim 2 , wherein the rotational speed is about 10% to about 15% less than a maximum rotational speed of the rollers.

4. The system of claim 1 , wherein the control valve comprises a piston having a valve disposed in a body.

5. The system of claim 4 , wherein the valve is configured to allow only a portion of operating fluid flow through the body when the control valve is in an off state.

6. The system of claim 4 , wherein the control valve further comprises a biasing member disposed in the body that applies a force to the piston.

7. The system of claim 6 , wherein the piston moves from a first position where the valve allows only a portion of operating fluid flow through the body to a second position where the valve allows all of the operating fluid flow through the body when the biasing member is compressed by the tension force.

8. The system of claim 7 , wherein the rollers are rotated at a first rotational speed when the piston is in the first position, and wherein the rollers are rotated at a second rotational speed when the piston is in the second position, wherein the first rotational speed is less than the second rotational speed.

9. The system of claim 1 , wherein the control valve comprises an electric actuator configured to control an amount of electric power supplied to rotate the rollers.

10. A tubular rotating system for rotating threaded tubulars, the system comprising:
a frame;
a plurality of rollers coupled to the frame and configured to rotate a tubular; and
a control valve coupled to the frame and configured to control power supplied to the rollers, wherein the rollers are rotated at a first rotational speed greater than zero when the control valve is in an off state, and at a second rotational speed greater than the first rotational speed when the control valve is in an on state.

11. The system of claim 10 , wherein the control valve comprises a piston having a valve disposed in a body.

12. The system of claim 11 , wherein the valve is configured to allow only a portion of power through the body when the control valve is in the off state.

13. The system of claim 11 , wherein the control valve further comprises a biasing member disposed in the body that applies a force to the piston.

14. The system of claim 13 , wherein the piston moves from a first position where the valve allows only the portion of power through the body when the control valve is in the off state, to a second position where the valve allows all of the power through the body when the control valve is in the on state such that the biasing member is compressed.

15. The system of claim 11 , wherein the rollers are rotated at the first rotational speed when no tension is applied to the piston, and wherein the rollers are rotated at the second rotational speed when tension is applied to the piston.

16. The system of claim 10 , further comprising a snub line coupled to the control valve and configured to move the control valve from the off state to the on state when tension is applied to the snub line.

17. The system of claim 16 , wherein when in the off state the control valve allows only a portion of the power to be supplied to the rollers, and wherein when in the on state the control valve allows full power to be supplied to the rollers.

18. The system of claim 10 , wherein the control valve comprises an electric actuator configured to control the power supplied to rotate the rollers.

19. The system of claim 10 , wherein the power is in the form of air, liquid, or electric power.

20. A tubular rotating system for rotating threaded tubulars, the system comprising:
a frame;
a plurality of rollers coupled to the frame and configured to rotate a tubular; and
a control valve coupled to the frame and configured to control rotational speed of the rollers based on a tension force;
wherein the control valve comprises a piston having a valve disposed in a body and a biasing member disposed in the body that applies a force to the piston;
wherein the piston is configured to move from a first position where the valve allows only a portion of operating fluid flow through the body to a second position where the valve allows all of the operating fluid flow through the body when the biasing member is compressed by the tension force; and
wherein the rollers are rotated at a first rotational speed when the piston is in the first position, the rollers are rotated at a second rotational speed when the piston is in the second position, and the first rotational speed is less than the second rotational speed.
