Abstract
A weight compensating pipe stabbing assembly utilizes bail mounting members operationally attached to bail members of a drilling rig. At least one compensation cylinder is mounted to each bail mounting member, while a cable or other linkage member extends from each cylinder assembly to a set of single joint elevators.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . An apparatus for stabbing of pipe and other tubular goods comprising:
a) at least one elongate body member adapted to operationally attach to a bail of a drilling rig, wherein said at least one elongate body member further comprises an upper end, a lower end and a receptacle disposed at said lower end configured to receive a portion of an eye of said bail; and b) a fluid operated cylinder mounted to said at least one elongate body member.
2 . The apparatus of claim 1 , further comprising:
a) a pipe elevator; and b) a cable having a first and a second end, wherein said first end is operationally attached to said fluid operated cylinder and said second end is operationally attached to said pipe elevator.
3 . The apparatus of claim 2 , wherein said fluid operated cylinder compensates for the weight of a section of pipe gripped by said pipe elevator.
