Abstract
Example systems for wrench assembly bumper plates. One example system may comprise a wrench assembly for assisting with attaching drill segments to, and/or separating drill segments from, a drill string. The wrench assembly may comprise a pair of arms. Each arm may comprise a bumper plate. The bumper plate may be shaped to be removably mountable to either of the pair of arms in a location where the bumper plate receives impact force when the arm makes contact with a drill segment.
Claims22
A wrench assembly for assisting with attaching drill segments to, and/or separating drill segments from, a drill string, the wrench assembly comprising:
- a pair of arms, each arm comprising a bumper plate shaped to be separately removably mountable to both:
- a first one of the pair of arms in a first arm impact location where the bumper plate receives impact force when the first one of the arms makes contact with a drill segment;
- or
- a second one of the pair of arms in a second arm impact location where the bumper plate receives impact force when the second one of the arms makes contact with the drill segment.
A kit for servicing an arm of a wrench assembly for assisting with attaching drill segments to, and/or separating drill segments from, a drill string, the kit comprising:
- a bumper plate;
- and
- a cover plate embodied separately from the bumper plate;
- wherein the bumper plate is shaped for mounting to the arm in a location where the bumper plate receives impact force when the arm makes contact with a drill segment;
- wherein the cover plate is shaped for mounting to the arm in a location spaced apart from the bumper plate to thereby cover an access to an interior of a housing of the arm.
A replacement bumper plate for replacing an existing bumper plate of an arm of a wrench assembly for assisting with attaching drill segments to, and/or separating drill segments from, a drill string, the replacement bumper plate shaped for mounting to the arm in a location where the replacement bumper plate receives impact force when the arm makes contact with a drill segment and in a location spaced apart from a cover plate mounted to the arm to cover an access to an interior of a housing of the arm.
