Tubular handling tool
View Patent ↗Embodiments of the invention generally relate to a tubular handling tool. The tool may include a base and a ring or sleeve member. The tool may further include an actuation member configured to move or rotate the ring or sleeve member relative to the base. Additionally, the tool may include a clamp or dog member attached to the base. The clamp or dog member is configured to move between a radially retracted position and a radially extended position as the ring or sleeve member moves or rotates relative to the base.
1. A tool for use with a tubular, the tool comprising:
a base;
a sleeve member;
an actuation member configured to rotate the sleeve member relative to the base, wherein the actuation member is pivotally coupled to the sleeve member and to the base; and
a dog member coupled to the base, wherein the dog member is configured to move between a radially retracted position and a radially extended position by the sleeve member as the sleeve member rotates relative to the base.
2. The tool of claim 1 , wherein the dog member is disposed in an opening formed in the base.
3. The tool of claim 2 , wherein the dog member is movable into an opening formed in the sleeve member to the radially extended position, and wherein the dog member is moveable out of the opening formed in the sleeve member to the radially retracted position.
4. The tool of claim 1 , wherein the sleeve member includes a support member coupled to or integral with the sleeve member, the support member having an angled slot formed therein.
5. The tool of claim 4 , wherein the dog member is coupled to the support member by a connection member that is movable within the angled slot.
6. The tool of claim 5 , wherein rotation of the sleeve member relative to the base in one direction moves the connection member along the angled slot to move the dog member to the radially retracted position.
7. The tool of claim 6 , wherein rotation of the sleeve member relative to the base in an opposite direction moves the connection member along the angled slot to move the dog member to the radially extended position.
8. The tool of claim 1 , further comprising a pair of ears coupled to the base from which the tool is suspended.
9. The tool of claim 1 , wherein the sleeve member is formed from two partially circular sections coupled together.
10. The tool of claim 9 , wherein the two partially circular sections are coupled together using connection members.
11. The tool of claim 1 , further comprising a tubular member coupled to the base, the tubular member configured to be engaged by an elevator.
12. The tool of claim 1 , further comprising a guide member coupled to the base.
13. The tool of claim 1 , wherein the sleeve member is disposed partially about the circumference of the base.
14. The tool of claim 1 , wherein the actuation member is in an retracted position when the dog member is in the radially extended position.
15. The tool of claim 1 , further comprising a second dog member coupled to the base, wherein the second dog member is configured to move between the radially retracted position and the radially extended position by the sleeve member as the sleeve member rotates relative to the base.
16. A method of gripping a tubular, comprising:
positioning a tool adjacent to the tubular, the tool having a base, a sleeve member, an actuation member pivotally coupled to the sleeve member and to the base, and a dog member;
rotating the sleeve member relative to the base using the actuation member; and
gripping the tubular by moving the dog member into engagement with the tubular as a result of the rotation of the sleeve relative to the base.
17. The method of claim 16 , further comprising rotating the sleeve member relative to the base in one direction to move the dog member into engagement with the tubular, and rotating the sleeve member relative to the base in an opposite direction to move the dog member out of engagement with the tubular.
18. The method of claim 16 , further comprising moving a tapered surface of the sleeve member into engagement with a tapered surface of the dog member to move the dog member into engagement with the tubular.
19. The method of claim 16 , wherein the sleeve member includes a support member coupled to or integral with the sleeve member, the support member having an angled slot formed therein, and wherein the dog member is coupled to the support member by a connection member that is movable within the angled slot.
20. The method of claim 19 , wherein rotating the sleeve member relative to the base comprises rotating the sleeve member relative to the base in one direction to move the connection member along the angled slot and thereby move the dog member into engagement with the tubular.
21. The method of claim 20 , further comprising rotating the sleeve member relative to the base in an opposite direction to move the connection member along the angled slot and thereby move the dog member out of engagement with the tubular.
22. The method of claim 16 , wherein the sleeve member is disposed partially about the circumference of the base.
23. The method of claim 16 , further comprising a pair of ears coupled to the base from which the tool is suspended.
24. The method of claim 16 , wherein the sleeve member is formed from two partially circular sections coupled together.
25. The method of claim 24 , wherein the two partially circular sections are coupled together using connection members.
26. The method of claim 16 , further comprising a tubular member coupled to the base, the tubular member configured to be engaged by an elevator.
27. The method of claim 16 , further comprising a guide member coupled to the base.
