Appl. No.:

11/422291

Inventors:

David R. Hall - Provo UT, US
Jay Reynolds - Provo UT, US
David Fox - Provo UT, US
Thomas Morris - Provo UT, US

International Classification:

B66C 1/22

US Classification:

294 8152, 294 8156, 294 816, 294907

Abstract:

In one aspect of the present invention, a lifting assembly has a frame structure with a translatable support element. The support element has a load-bearing surface and a screw-form. The screw-form is threadedly connected to a gear which is in mechanical communication with a power source, which may be an electric motor. The load-bearing surface is fixed to a shaft of the translatable support element and at least a portion of the load-bearing surface is angularly oriented with respect to the shaft. A guide with at least one end fixed to the frame structure is adapted to adjust the rotational orientation of the load-bearing surface.

International Classification:

B23B 31/30

US Classification:

82165, 279 402, 279 411, 279126

Abstract:

A method of dialing a workpiece having an axis into a chuck includes providing a chuck assembly having a plurality of independent hydraulically controlled jaws distributed about a central axis, each jaw having first and second hydraulic chambers. The method further includes the steps of inserting a portion of the workpiece into the chuck assembly, pumping hydraulic fluid uniformly into each of the first chambers until the jaws are substantially touching the perimeter of the workpiece, and adjusting one or more of the jaws to align the axis of the workpiece with the central axis of the chuck assembly by pumping hydraulic fluid into at least one of the chambers of at least one of the jaws. The method also includes the step of pumping hydraulic fluid uniformly into each of the first chambers until the jaws are clamped around the perimeter of the workpiece at a predetermined pressure.

Assignee:

Schlumberger Technology Corporation - Houston TX

International Classification:

B66C 1/42

US Classification:

294106, 294 8161

Abstract:

A clamping assembly for use in gripping an object. The clamping assembly includes a pair of opposed jaws, with each jaw having a pivot end pivotally attached to a frame structure, a clamp end opposite the pivot end, and a socket located between the clamp end and the pivot end. The clamping assembly further includes first and second balls rotatably mounted in the sockets of the opposed jaws, and a gear assembly connected to both of the first and second balls that includes a primary gear mechanically associated with a power source. Rotation of the primary gear by the power source results in actuation of the clamping assembly.
