LOW MAINTENANCE IRON ROUGHNECK SYSTEM WITH REPLACEABLE MODULAR COMPONENTS THEREOF

摘要

An automated roughneck system is described which includes a base module, a removable spinner module for spinning pipe to connect or disconnect drill pipes at threaded interfaces, which automatically self-centers itself around a drill pipe and automatically adjusts to a varied range of drill pipe diameters, a removable torque module for torqueing drill pipe and which automatically self-centers itself around a drill pipe and automatically adjusts to a varied range of drill pipe diameters, an extension module including a first plurality of extension arms that extend between a central hub of the extension module and the base module, and a second plurality of extension arms that extend between the central hub and supporting structure that supports the spinner and torque modules thereon, with each of the base, extension, spinner, and torque modules being hydraulically powered, and being controlled by controls at the remote operator control console.
