摘要:
A pipe handling assembly includes: a pipe engaging apparatus including a pipe gripping mechanism connectable to a top drive such that the top drive transmits rotational movement and axial movement to the pipe gripping mechanism; a pipe handling device for mounting onto the pipe engaging apparatus, the pipe handling device including a link hanger mounted on the pipe engaging apparatus, a link arm having a first end pivotally connectable to the link hanger and an outboard end selected to carry a pipe into a position to be gripped by the pipe engaging apparatus; a bearing for isolating rotational movement to the pipe gripping mechanism from the link hanger; and a connection for rigidly connecting the link hanger to the pipe engaging apparatus during operation of the pipe handling assembly, the connection selected to substantially prevent the link hanger from rotating with the pipe gripping mechanism should the bearing seize.
