Rail vehicle for the transport of material on a suspension rail in underground working

摘要

In a rail vehicle for the transport of material on a suspension rail in underground working, which rail vehicle has a lifting beam with attached lifting devices which have a drive consisting of a thrust-piston mechanism and carry one bearing plate each, in each case allocated to an end face of the lifting beam, and serve to sling a load, in particular by locking a pivot pin fixed to one end face each of a railway container, provision is made according to the invention for each lifting device (10, 11) to consist of a lever linkage which is positively actuated in planes parallel to the longitudinal centre plane of the lifting beam and has an asymmetric Scotch-yoke mechanism (17) whose links (18, 19) are articulated on the lifting beam (1) and whose rectilinear sliding pair (24) is attached to the thrust-piston mechanism (12) supported in a lever-linkage loop (32, 33) starting from its links (18, 19), and for each bearing plate (14) to be suspended on the outer end (37), pointing towards the relevant end (8, 9) of the lifting beam, of a longer link (19) of the Scotch-yoke mechanism (17) (Fig. 1). <IMAGE>
