LOW MAINTENANCE IRON ROUGHNECK SYSTEM WITH REPLACEABLE MODULAR COMPONENTS THEREOF
First Claim
1. An automated roughneck system, comprising:
- a base module,a removable spinner module for spinning pipe to connect or disconnect drill pipes at threaded interfaces, the spinner module configured to automatically self-center itself around a drill pipe and to automatically adjust to a varied range of drill pipe diameters,a removable torque module for torqueing drill pipe, the torque module configured to automatically self-center itself around a drill pipe and to automatically adjust to a varied range of drill pipe diameters,an extension module connected to the base module and configured to support the spinner and torque modules thereon, the extension module having a retracted position and an extended position, the extension module including a central hub and two paired sets of forward extension arms, each pair of forward extension arms in spaced relation to the other on opposite sides of the central hub, with upper ends of the paired sets of forward extension arms connected to the central hub and lower ends of the paired sets of forward extension arms connected to supporting structure that supports the spinner module and torque module thereon, the extension module including two paired sets of rearward extension arms, each pair of rearward extension arms in spaced relation to the other on opposite sides of the central hub, with upper ends of the paired sets of rearward extension arms connected to the central hub and lower ends of the paired sets of rearward extension arms connected to the base module, andan operator control console remote from the roughneck system, each of the base module, extension module, spinner module, and torque module being hydraulically powered, and being controlled by controls at the remote operator control console.

Abstract
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.

22. An automated roughneck system, comprising:
-
a base module, a removable spinner module for spinning pipe to connect or disconnect drill pipes at threaded interfaces, the spinner module configured to automatically self-center itself around a drill pipe and to automatically adjust to a varied range of drill pipe diameters, a removable torque module for torqueing drill pipe to make-up or break-out the pipe, the torque module configured to automatically self-center itself around a drill pipe and to automatically adjust to a varied range of drill pipe diameters, the torque module including; at least two clamp cylinders, each in opposed facing relation to the other, with an opening provided through the torque module and between the opposed clamp cylinders to accommodate a drill pipe vertically therethrough, each clamp cylinder including a front block laterally movable into and out of the opening via a piston action provided to it by a piston cylinder within the clamp cylinder, each front block having a set of pipe grip fingers affixed thereto for engaging the pipe in the opening, wherein the set of pipe grip fingers include fingers that pivot or articulate around a portion of pipe as the front block moves laterally into the opening to push the set of pipe grip fingers onto and around the pipe, with the opposed sets of pipe grip fingers on either side of the pipe configured to apply a uniform gripping load around the pipe, an extension module having a retracted position and an extended position and including a first plurality of extension arms that extend from a central hub of the extension module to connect to the base module, and a second plurality of extension arms that extend from the central hub to connect to supporting structure that supports the spinner and torque modules thereon, and an operator control console remote from the roughneck system, each of the base module, extension module, spinner module, and torque module being hydraulically powered, and being controlled by controls at the remote operator control console.
