Powered support assembly, in particular shield-type powered support assembly, with walking mechanism

摘要

In the space between its two floor skids (2) connected in parallel to one another, the powered support assembly (1) according to the invention has a walking mechanism (8) with a slipped-in pushing cylinder (10) and a pushing beam (9) which makes the connection to the walking abutment (face conveyor). The pushing beam (9) consists of a flat plate which at the rear end carries a guide and bearing bracket (12) which is guided on sliding rails (23) of the floor skids by means of guide members (22). The cylinder part of the pushing cylinder (10) is at the same time mounted on the guide and bearing bracket (12) in a vertically pivotable manner in a pivot bearing. The piston rod (19) of the pushing cylinder (10) acts on a cross-piece (21) arranged between the two floor skids (2). The arrangement is made in such a way that the pushing beam (9) is supported and guided at a distance from the floor level on the sliding rails (23) of the floor skids. In addition, the invention relates to a convenient design of the cross-piece (21) serving as a connection for the piston rod. <IMAGE>
