METHOD AND APPARATUS FOR HANDLING TUBULAR GOODS
摘要:
An apparatus for handling tubular goods which includes an elongate body having a coupling end adapted for mating engagement with a tubular good. The coupling end includes a structural member (4), a flexible cylindrical (3) cage and a pressure member. Longitudinal strips (80) joined at their opposed ends (82) form the cage coaxial with and connected to the structural member (4) of the body. The coaxial pressure member is disposed in an annulus between the structural member and the cage. The pressure member is adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.
