Coking coal stamping machine clamping wedge - retaining rammer in raised position between inclined abutments

摘要

A device to hold raised rammers of a stamping machine for use in stamping operations of coking coal in a raised position consists of a thrust block for each rammer rod. A first internal surface in the thrust block is parallel to the rammer rod, and a second surface, facing the first, includes an upward angle with it. A clamping wedge is urged by gravity in the gap between these surfaces and is raised by a power cylinder to let the rammer drop. This device is simple in design and combines a functional reliability with little maintenance requirements. (39JB).
