Abstract
A pipe retrieval machine has a frame defining a decoupling region and a travel axis and a transporting mechanism having a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is disposed between the first and second gripping structures. A drive system is configured to move the first and second gripping structures at a steady state speed to direct the pipe along the travel axis. A decoupling device in the decoupling region has a decoupler that is automatically operable to engage a locking part of the coupling. The decoupling device is configured to selectively and automatically stop the pipe relative to the decoupling device, to disassemble at least one pipe section from the pipe, to move the detached pipe section from the machine, and to advance the remaining pipe for disassembly.
