1. A flange for use with a tong, comprising:
a top plate movably connected to a bottom plate;
two or more abutments disposed between the plates;
one or more force sensing members disposed between the two or more abutments, wherein rotating the top plate relative to the bottom plate moves two of the abutments closer together.
2. The flange of claim 1, wherein each abutment comprises a wedge.
3. The flange of claim 2, wherein the flange comprises four wedges.
4. The flange of claim 2, wherein two wedges are attached to the top plate and two wedges are attached to the bottom plate.
5. The flange of claim 3, wherein each of the one or more force sensing members comprises a cylinder.
6. The flange of claim 5, wherein at least one cylinder is disposed between a wedge of the top plate and a wedge of the bottom plate.
7. The flange of claim 5, wherein at least one cylinder comprises a piston at least partially disposed in the cylinder.
8. The flange of claim 7, wherein moving the one or more wedges closer together compresses the piston.
9. The flange of claim 8, wherein the piston further comprises a bearing disposed at a contact end.
10. The flange of claim 9, wherein at least one elongated slot is formed in the bottom plate for connection with the top plate.
11. The flange of claim 10, wherein the cylinder further comprises a second bearing.
12. The flange of claim 1, wherein one or more force sensing members is disposed between a wedge of the top plate and a wedge of the bottom plate.
13. The flange of claim 12, wherein the one or more sensing members comprises a piston at least partially disposed in the cylinder.
14. The flange of claim 13, wherein moving the one or more wedges closer together compresses the piston.
15. The flange of claim 14, wherein the piston further comprises a bearing disposed at a contact end.
16. A tong for providing a predetermined torque to a connection between a first tubular and a second tubular, the tong comprising:
at least two jaws, at least one of the jaws being movable inwardly towards the other to grasp the first tubular; and
a torque measuring flange for measuring the torque applied to the tong, the flange comprising:
a top portion movably attached to a bottom portion;
one or more inserts disposed in the flange; and
one or more cylinders disposed between the inserts, the one or more cylinders actuatable by the inserts.
17. The tong of claim 16, wherein the one or more inserts comprises:
two torque inserts attached to the top portion and two static inserts attached to the bottom portion.
18. The tong of claim 18, wherein the one or more cylinders include a piston, wherein rotating the top plate causes the two torque inserts to move closer to the two static inserts, thereby compressing the piston into the one or more cylinders.
19. The tong of claim 16, further comprising an indexing assembly to determine a position of the first tubular relative to the jaws, the assembly including:
a first portion extending at least partially into an area defined by a vertical plane extending substantially between the jaws, the first portion retractable from the area upon contact with the first tubular; and
an indicator, the indicator showing the movement of the first portion and the movement of the first tubular; and
20. The tong of claim 19, wherein the indexing assembly further comprises a mounting bracket.
21. The tong of claim 20, wherein the indexing assembly further comprises one or more biasing members coupling the first portion to the mounting bracket.
22. A method for preventing damage to a tubular body when such tubular body is gripped and turned by a tong comprising:
supplying a tong having a tubular position indicator for indicating a position of the tubular body relative to the tong, and the tong having a torque flange mounted thereto for indicating a torque applied to the tubular body when the tubular body is turned by the tong, wherein the torque flange includes
a top portion movably attached to a bottom portion;
one or more abutments disposed between the top portion and the bottom portion; and
one or more force sensing members disposed proximate the one or more abutments, wherein application of torque by the tong moves some of the abutments closer together;
indicating the position of the tubular body relative to the tong; and
measuring the torque applied to the tubular body when the tubular body is turned by the tong.
The claims below are in addition to those above.
