Abstract
This invention provides a hydraulically-actuated pipe clamp for sealing leaks in pipe lines located in remote or hazardous places. The pipe clamp consists of a split block having hinged jaws that may be clamped around a pipe by a hydraulic actuator. The jaws are then mechanically latched in place so that the clamp will remain closed after the hydraulic source has been disconnected.
Claims5
A hydraulically-actuated pipe clamp for manipulation by a robot, comprising:
- a split block, having a bore, said split block consisting of two hinged-together jaws;
- a first double-acting hydraulic means for spreading apart the hinged-together jaws of said split block to allow positioning said split block over a desired portion of a pipe having a preselected diameter and for clamping the hinged-together jaws of said split block around said pipe;
- a second double-acting hydraulic means for rotating a first and a second latching means over said jaws when clamped around said pipe to confine said jaws to a clamped configuration.
