ADJUSTABLE LOCK-OUT RAM FOR PRODUCTION BOP APPLICATIONS

摘要

Systems and methods for gripping a polished rod that extends into a hydrocarbon production well include a clamping assembly that is moveable between an unengaged position where the clamping assembly is spaced apart from the polished rod, and an engaged position where the clamping assembly engages the polished rod. The clamping assembly includes a recess located in a moveable clamping member, the recess having a supporting surface. The clamping assembly also includes an adapter sized to fit within the recess and to be supported on the supporting surface, the adapter having a gripping surface facing out of the recess. The adapter is positioned to grip the polished rod with the gripping surface when the clamping assembly is in the engaged position.
