Orienting device for a powered support assembly

摘要

Orienting devices in the floor skids of powered support assemblies serve to correct the relative position of adjacent powered support assemblies and to correct the position of the powered support assemblies relative to the face conveyor. Hitherto they have extended into the tracks between powered support assemblies adjacent to the floor skids and when not in use have thereby hindered the discharge of broken material and fine coal. According to the invention, the orienting device (7) is now integrated in the floor skid (2). Here, the pivot axis (15) of the orienting arm (16) is arranged in such a way that, in the swung-in state, the orienting arm (16) forms part of the skid side wall (23). The orienting arm (16) is designed in a shell shape, so that in every extension position the orienting cylinder (13) lies in the orienting arm (16) in such a way as to be protected against the effects of the surrounding area. <IMAGE>
