Patent number: 8037949Abstract: A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment.Type: GrantFiled: April 16, 2010Date of Patent: October 18, 2011Assignee: Varco I/P, Inc.Inventors: Daniel Juhasz, George Boyadjieff, Brian L.

Patent number: 6691801Abstract: A load compensator is disclosed for use in connection with a pipe running tool. The load compensator includes an outer housing connected to the portion of the pipe running tool that holds the pipe segment. A piston is disposed within the housing, and is connected to a top drive system of the pipe running tool. The housing is formed with a first port through which pressurized air is delivered inside the housing to drive the piston within the housing. A second port is disposed at a selected location on the housing, such that when the piston is advanced past the second port, pressurized air passes through the port, and causes the control circuit to stop delivering air through the first port. Once pressurized air no longer flows through the second port, the control circuit causes air to be delivered to the first port.Type: GrantFiled: September 14, 2001Date of Patent: February 17, 2004Assignee: Varco I/P, Inc.Inventors: Daniel Juhasz, George Boyadjieff, Brian L.
