Abstract
An apparatus for handling tubular goods includes a rigid elongate body having an upper end and a lower end. A coupling to facilitate attachment to a drive head is positioned at the upper end of the body, including an upper universal joint connection.
A gripping assembly, adapted for engaging a tubular good, is positioned at the lower end, including a lower universal joint connection. The combination of the upper universal joint connection and the lower universal joint connection enables lateral movement between the drive head and the gripping assembly during transmission of torque.
A gripping assembly, adapted for engaging a tubular good, is positioned at the lower end, including a lower universal joint connection. The combination of the upper universal joint connection and the lower universal joint connection enables lateral movement between the drive head and the gripping assembly during transmission of torque.
Claims (19)
1. An apparatus for handling tubular goods, comprising:
a rigid elongate body having an upper end and a lower end;
means for attachment to a drive head positioned at the upper end of the body, including an upper universal joint connection; and a gripping assembly adapted for engaging a tubular good positioned at the lower end, including a lower universal joint connection, such that a combination of the upper universal joint connection and the lower universal joint connection enables lateral movement between the drive head and the gripping assembly during transmission of torque.
a rigid elongate body having an upper end and a lower end;
means for attachment to a drive head positioned at the upper end of the body, including an upper universal joint connection; and a gripping assembly adapted for engaging a tubular good positioned at the lower end, including a lower universal joint connection, such that a combination of the upper universal joint connection and the lower universal joint connection enables lateral movement between the drive head and the gripping assembly during transmission of torque.
2. The apparatus as defined in Claim 1, wherein means are provided for selectively locking each of the first universal joint connection and the second universal joint connection to prevent lateral movement during selected operations.
3. The apparatus as defined in Claim 1, wherein the body is tubular having a peripheral side wall with a plurality of openings arranged circumferentially around the body, and the universal joint connection includes an insert positioned within the tubular body with radial pins that are adapted to engage the openings.
4. The apparatus as defined in Claim 3, wherein the openings are axial slots, with each slot oriented parallel to an axis of the body, the pins being axially movable along the slots.
5. The apparatus as defined in Claim 4, wherein each of the axial slots includes an axial leg and a circumferential leg, the pins being immobilized when in the circumferential leg of each slot.
6. The apparatus as defined in Claim 5, wherein the slots are "L" shaped.
7. The apparatus as defined in Claim 1, wherein there is a fluid path provided through each of the first universal joint connection and the second universal joint connection.
8. The apparatus as defined in Claim 1, wherein the means for engaging a tubular good is mechanically activated.
9. The apparatus as defined in Claim 1, wherein the means for engaging a tubular good is a male coupling.
10. The apparatus as defined in Claim 9, wherein the male coupling includes:
a structural member;
longitudinal strips joined at least one end to form a flexible cylindrical cage coaxial with and connected to the structural member of the body; and at least one coaxial pressure member disposed in an annulus between the structural member and the cage, the pressure member being adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.
a structural member;
longitudinal strips joined at least one end to form a flexible cylindrical cage coaxial with and connected to the structural member of the body; and at least one coaxial pressure member disposed in an annulus between the structural member and the cage, the pressure member being adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.
11. The apparatus for handling tubular goods as defined in Claim 10, wherein the structural member is a mandrel which, together with the cage and pressure member, forms the male coupling.
12. The apparatus for handling tubular goods as defined in Claim 11, wherein the cage is connected to the structural member by a connection which allows a limited range of relative axial movement between the cage and the structural member, such that axial load applied to the structural member loads the pressure member to increase the gripping force.
13. The apparatus for handling tubular goods as defined in Claim 12, wherein the longitudinal strips of the cage having structurally interlocking edges, thereby increasing the torsion capacity of the cage.
14. The apparatus for handling tubular goods as defined in Claim 13, wherein the pressure member includes a confined elastomer in combination with means to axially compress the confined elastomer to cause radial displacement.
15. The apparatus for handling tubular goods as defined in Claim 14, wherein an axially movable setting member serves to axially compress the confined elastomer.
16. The apparatus for handling tubular goods as defined in Claim 1, wherein biasing means are provided to bias the at least one articulated coupling into axial alignment with the tubular body.
17. The apparatus for handling tubular goods as defined in Claim 7, wherein the biasing means is one of a mechanical spring or a pneumatic spring.
18. The apparatus for handling tubular goods as defined in Claim 10, wherein the pressure member includes a confined cylindrical spring assembly in combination with means to axially load the cylindrical spring assembly to cause radial displacement.
19. The apparatus for handling tubular goods as defined in Claim 16, wherein an axially movable setting member serves to axially load the cylindrical spring assembly.
