Method and device for holding and releasing a cable in a pipe splitter

摘要

A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

主权项

1. A cable retention and release mechanism comprising:
a cable gripping device collar including a cable gripping device receiving inner surface, the cable gripping device receiving inner surface tapers inwardly from a collar distal end toward a collar proximal end; a cable gripping device positioned along the cable gripping device receiving inner surface, the cable gripping device includes a cable gripping device outer surface and a cable passage, the cable gripping device outer surface tapers inwardly from a device distal end toward a device proximal end; a jack configured for movable coupling with the cable gripping device collar; and wherein the cable gripping device is moved between an interference fit orientation and a disengaged orientation as a result of movement of the jack,
in the interference fit orientation the cable gripping device outer surface is interference fit with the cable gripping device receiving inner surface, and the cable gripping device clamps a cable within the cable passage as a result of the interference fit, andin the disengaged orientation movement of the jack is transmitted to the cable gripping device and disengages the interference fit between the cable gripping device receiving inner surface and the cable gripping device outer surface and disengages clamping of the cable.
