Articulated connection between canopy and hydraulic prop of a powered support assembly, in particular a shield-type powered support assembly

摘要

According to the invention the articulated connection between canopy (1) and prop head (4) is secured in the recess (6) of the canopy by means of a locking fork (10) which is releasably fastened at its fork web (12), preferably to the underside of the canopy, e.g. by means of a coupling bolt (16) and which with its fork legs (11) closes pin receptacles (9) at the underside into which supporting pins (8) arranged on the prop head (4) engage. The locking fork (10) is supported with its fork legs (11) on fixed supporting abutments (19) inside the canopy recess (6). <IMAGE>
