Abstract
In one embodiment, a gripping system for a tong for making up and breaking out tubulars is provided. The gripping system is coupled to the rotary of the tong. The gripping system includes an active jaw and two passive jaws disposed interior to the rotary. Preferably, the two passive jaws are separately by less than 120 degrees from each other and are pivotally connected to rotary. The gripping system is adapted and arranged to allow each passive jaw to react the same amount of force as the gripping force applied by the active jaw. In another embodiment, a rotary locking apparatus is provided to lock or unlock the rotary of the tong.
Claims (30)
1. An apparatus for handling a tubular, comprising:
a housing for receiving the tubular; and a plurality of gripping members disposed in the housing for gripping the tubular, wherein at least one of the plurality of gripping members are pivotally coupled to the housing.
a housing for receiving the tubular; and a plurality of gripping members disposed in the housing for gripping the tubular, wherein at least one of the plurality of gripping members are pivotally coupled to the housing.
2. The apparatus of claim 1, further comprising at least one guiding element disposed in the housing for engaging the plurality of gripping members.
3. The apparatus of claim 2, wherein the at least one guiding element prevents the plurality of gripping members from twisting as torque is applied to the tubular.
4. The apparatus of claim 2, wherein the plurality of gripping members and the at least one guiding element are arranged on a rotary.
5. The apparatus of claim 1, wherein the apparatus comprises a tong.
6. The apparatus of claim 1, wherein the plurality of gripping members comprise an active gripping member and one or more passive gripping members.
7. The apparatus of claim 6, wherein the one or more passive gripping members are adapted to react a first reaction force equivalent to a gripping force applied by the active gripping member.
8. The apparatus of claim 7, wherein the reactive force is directed toward the center of the tubular.
9. The apparatus of claim 7, wherein two passive gripping members are utilized.
10. The apparatus of claim 9, wherein the two passive gripping members are positioned less than 120 degrees apart.
11. The apparatus of claim 1, wherein at least one gripping member is fluidly operated.
12. The apparatus of claim 1, further comprising a rotary for rotating the gripping members.
13. The apparatus of claim 12, further comprising a rotary locking apparatus for locking an unlocking the rotary.
14. A method for handling a tubular, comprising:
providing a gripping apparatus having a plurality of gripping members coupled to a rotary;
pivoting at least one of the plurality of gripping members relative to the rotary;
gripping the tubular; and applying torque to rotate the tubular.
providing a gripping apparatus having a plurality of gripping members coupled to a rotary;
pivoting at least one of the plurality of gripping members relative to the rotary;
gripping the tubular; and applying torque to rotate the tubular.
15. The method of claim 14, wherein the plurality of gripping members comprise an active gripping member and one or more passive gripping members.
16. The method of claim 15, further comprising the one or more passive gripping members reacting a same amount of force as a gripping force applied by the active gripping member.
17. The method of claim 15, further comprising fluidly operating the active gripping member.
18. The method of claim 15, further comprising positioning two passive gripping members about 120 degrees or less from each other.
19. The method of claim 14, further comprising balancing the torque acting on the plurality of gripping members.
20. The method of claim 14, further comprising directing a reaction force toward a center of the tubular.
21. The method of claim 14, further comprising:
providing the rotary with a locking member; and providing a locking apparatus for moving the locking member between an open position and a closed position.
providing the rotary with a locking member; and providing a locking apparatus for moving the locking member between an open position and a closed position.
22. The method of claim 21, wherein the locking apparatus comprises:
a coupling element for engaging the locking member; and an actuator for moving the coupling element.
a coupling element for engaging the locking member; and an actuator for moving the coupling element.
23. The method of claim 22, further comprising rotating the actuator to move the locking member between the open and closed positions.
24. The method of claim 21, further comprising ensuring that the locking member is in the closed position prior to activating the plurality of gripping members.
25. An apparatus for handling a tubular, comprising:
a gripping member having a rotary and a locking member for locking the rotary; and a rotary locking apparatus having:
a coupling element for engaging the locking member; and an actuator for moving the locking member between an open position and a closed position.
a gripping member having a rotary and a locking member for locking the rotary; and a rotary locking apparatus having:
a coupling element for engaging the locking member; and an actuator for moving the locking member between an open position and a closed position.
26. The apparatus of claim 25, further comprising a carrier attached to the coupling element and coupled to the actuator.
27. The apparatus of claim 25, wherein rotation of the actuator moves the coupling element and the locking element between the open position and the closed position.
28. The apparatus of claim 25, wherein the coupling element comprises a magnet.
29. The apparatus of claim 25, further comprising a sensor for determining a position of the locking member.
30. The apparatus of claim 25, further comprising an offset member for positioning the coupling element away from engagement with the locking member.
