Pipe handling apparatus

摘要

Pipe handling apparatus and methods intended to facilitate the transportation of pipe between a rig floor and a rack of pipe. The pipe handling apparatus comprise in general a loading mechanism, which transports pipe between the pipe handler and a rig, and a racking mechanism, which transport pipe between a rack and the loader. The racking mechanism is adapted to selectively transport pipe from and deliver it to various levels in a rack of pipe. The racker comprises a pair of elevators, each of which has a pipe rest which is moveable between a hold position, in which pipe may be received therein and is restricted from rolling out of the pipe rest, and a release position, in which release position pipe may roll out of the pipe rest.

1. A pipe handling apparatus for transporting pipe between a rig floor and a pipe rack, said pipe handling apparatus comprising a loading mechanism adapted to transport pipe between said pipe handling apparatus and said rig floor and a racking mechanism for transporting pipe between said loading mechanism and said pipe rack, said racking mechanism comprising:
(a) an elevator comprising an elongated, vertically extending post and having a pipe rest adapted to receive a pipe horizontally therein; (b) said pipe rest being mounted on said elevator for rotation along a horizontal axis above said elevator post between a hold position, in which hold position said pipe may be received in said pipe rest and is restricted from rolling out of said pipe rest, and a release position, in which release position said pipe may mil out of said pipe rest; (c) a platform extending horizontally between said pipe rack and said loading mechanism; (d) said elevator post being mounted for vertical movement through an opening in said platform between a load position, in which load position said pipe rest is at a first elevation at which it may receive said pipe, and an unload position, in which said pipe rest is at a second elevation at which it may release said pipe by moving from its hold position to its release position.
