Abstract
A gripping apparatus (100) for supporting a tubular includes a longitudinal opening extending therethrough. A bowl (25) is formed on an inner wall of the housing to provide an incline surface for one or more gripping members (20). As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions (11, 12) coupled together using one or mores hinges (35). In one aspect, the bowl is formed as a recess in the inner wall (42) of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus.
Claims (32)
1. A gripping apparatus for supporting a tubular, comprising:
a housing having a longitudinal opening extending therethrough;
a bowl formed on an inner wall of the housing, wherein a surface of the bowl is recessed relative to one or more connectors; and one or more gripping members movable along the surface of the bowl.
a housing having a longitudinal opening extending therethrough;
a bowl formed on an inner wall of the housing, wherein a surface of the bowl is recessed relative to one or more connectors; and one or more gripping members movable along the surface of the bowl.
2. The gripping apparatus as claimed in claim 1, wherein the one or more connectors are curved to accommodate the recessed bowl.
3. The gripping apparatus as claimed in claim 2, wherein the one or more connectors comprise one or more hinges.
4. The gripping apparatus as claimed in claim 1, wherein the housing comprises two body sections coupled together using the one or more connectors.
5. The gripping apparatus as claimed in claim 4, wherein the one or more connectors are progressively curved to accommodate the recessed bowl.
6. The gripping apparatus as claimed in claim 1, further comprises one or more guide keys disposed on the surface of the bowl.
7. The gripping apparatus as claimed in claim 6, wherein each of the one or more gripping members include a guide slot for mating with a respective guide key.
8. The gripping apparatus as claimed in claim 6 or 7, wherein the one or more guide keys minimize the rotational movement of the one or more gripping members relative to the recessed bowl.
9. The gripping apparatus as claimed in claim 1, further comprising a leveling ring connected to the one or more gripping members for synchronizing the movement of the one or more gripping members.
10. The gripping apparatus as claimed in claim 9, wherein the leveling ring includes one or more guide bearings.
11. The gripping apparatus as claimed in claim 10, wherein one or more guide tracks are formed on an inner wall of an upper portion of the housing.
12. The gripping apparatus as claimed in claim 11, wherein each of the one or more guide bearings are movable within a respective guide track.
13. The gripping apparatus as claimed in claim 11 or 12, wherein the one or more guide tracks minimize the rotational movement of the leveling ring with respect to the housing.
14. The gripping apparatus as claimed in claim 1, wherein the housing further comprises one or more abutments for mating with a rotary table.
15. The gripping apparatus as claimed in claim 14, wherein the one or more abutments minimize the rotational movement of the gripping apparatus with respect to the rotary table.
16. The gripping apparatus as claimed in claim 14 or 15, wherein the one or more abutments comprise one or more blocks.
17. The gripping apparatus as claimed in claim 1, wherein the housing includes a flange for mounting to a rotary table.
18. The gripping apparatus as claimed in claim 1, furthering comprising a cover assembly selectively attachable to the housing.
19. The gripping apparatus as claimed in claim 18, wherein the cover assembly includes two portions, each attachable to a respective portion of the housing.
20. The gripping apparatus as claimed in claim 18, wherein the cover assembly includes a hole coaxially aligned with the opening of the housing.
21. The gripping apparatus as claimed in claim 20, further comprising one or more guide rollers to facilitate movement of the tubular.
22. The gripping apparatus as claimed in claim 21, wherein the one or more guide rollers are positioned around the hole of the cover assembly in a manner capable of centering the pipe.
23. The gripping apparatus as claimed in claim 21 or 22, wherein the one or more guide rollers are adjustable to accommodate different sized tubular.
24. The gripping apparatus as claimed in claim 23, wherein the one or more guide rollers include: a clevis having a shaft at one end; a pin for coupling a roller to the clevis; and a mounting assembly, wherein the shaft is adjustable within the mounting assembly.
25. The gripping apparatus as claimed in claim 1, further comprising one or more guide rollers to facilitate movement of the tubular.
26. The gripping apparatus as claimed in claim 25, wherein the one or more guide rollers are positioned in a manner capable of centering the tubular.
27. The gripping apparatus as claimed in claim 25, wherein the one or more guide rollers are adjustable to accommodate different sized tubular.
28. The gripping apparatus as claimed in claim 25, wherein the one or more guide rollers include: a clevis having a shaft at one end; a pin for coupling a roller to the clevis; and a mounting assembly, wherein the shaft is adjustable within the mounting assembly.
29. The gripping apparatus of claim 1, wherein the gripping apparatus is configured so that the one or more gripping members remain substantially within the housing when the one or more gripping members are not contacting the tubular.
30. The gripping apparatus of claim 1, wherein the longitudinal opening is substantially oval.
31. The gripping apparatus of claim 1, wherein the apparatus is flush with the rotary table.
32. A method for supporting a tubular, comprising:
providing a gripping apparatus having a housing and a bowl formed therein, wherein the bowl is recessed relative to one or more connectors of the housing;
placing one or more gripping members on the bowl;
moving the gripping members along the bowl; and engaging the tubular with the gripping members; and positioning the gripping apparatus flush with the rotary table.
providing a gripping apparatus having a housing and a bowl formed therein, wherein the bowl is recessed relative to one or more connectors of the housing;
placing one or more gripping members on the bowl;
moving the gripping members along the bowl; and engaging the tubular with the gripping members; and positioning the gripping apparatus flush with the rotary table.
