Method and apparatus for extended arm stabbing of pipe and other tubular goods
Abstract
An extended stabbing assembly permits quick and efficient installation of a stabbing guide on a first threaded connection member from a safe distance away from said threaded connection member, and removal of said stabbing guide following completion of a pipe make-up (connection) operation. A pair of opposing arcuate arm members are attached to a yoke member, which is attached to an elongate extension rod. The opposing arcuate members can be selectively alternated between a first (substantially open or spread apart) position and a second (partially closed or inwardly pointing) position. Tapered pipe guide members extend from the upper surface of the arcuate arm members and yoke member.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . An extended pipe stabbing assembly comprising:
a) an elongate extension member having a distal end and a proximate end; b) a pair of opposing gripping members pivotally disposed at said distal end, wherein said opposing gripping members are adapted to selectively shift between a first substantially spread apart position and a second partially closed position; and c) a plurality of tapered guide members attached to said opposing gripping members or said elongate extension member.
2 . The extended pipe stabbing assembly of claim 1 , wherein the length of said elongate extension member is in the range from 4 to 10 feet.
3 . The extended pipe stabbing assembly of claim 1 , wherein each of said pair of opposing gripping members has an arcuate shape.
4 . The extended pipe stabbing assembly of claim 1 , wherein said plurality of tapered guide members are removably attached to said opposing gripping members or said elongate extension member.
5 . An extended pipe stabbing assembly comprising:
a) an elongate tubular member having a proximate end, a distal end and a central through bore extending from said proximate end to said distal end; b) a drive rod slidably disposed within said central bore of said elongate tubular member, wherein said drive rod extends substantially along the entire length of said elongate tubular member; c) a yoke member disposed at said distal end of said elongate tubular member; d) a pair of opposing gripping members pivotally connected to said yoke member, wherein said opposing gripping members are adapted to selectively shift between a first substantially spread apart position and a second partially closed position; and e) a plurality of tapered guide members connected to said opposing gripping members and said yoke member.
6 . The extended pipe stabbing assembly of claim 5 , wherein said pair of opposing gripping members shift between said first and second positions in response to axial movement of said drive rod.
7 . The extended pipe stabbing assembly of claim 1 , wherein the length of said elongate tubular member is in the range from 4 to 10 feet.
8 . The extended pipe stabbing assembly of claim 5 , wherein each of said pair of opposing gripping members has an arcuate shape.
9 . The extended pipe stabbing assembly of claim 5 , wherein said plurality of tapered guide members are removably attached to said opposing gripping members or said elongate extension member.
10 . The extended pipe stabbing assembly of claim 5 , wherein said pair of opposing gripping members and yoke members cooperate to form a substantially circular shape when said opposing gripping members are inJoin the waitlist — get patent alerts
