Propulsion system, in particular for suspended monorails for underground operations

摘要

A propulsion system, in particular for suspended monorails for underground operations, is illustrated and described, the said system having two running trolleys which are arranged on one behind the other in the direction of travel, having two hydraulic travel units (4, 5) and having a connection element, each running trolley having a clamping device and at least one of the two running trolleys being constantly located in its clamping position, that is to say one of the two clamping devices being only releasable whenever the other clamping device is in the clamping position, each hydraulic travel unit (4, 5) having a travel cylinder (10, 11), a working piston (12, 13) which can be acted on on both sides and a travel rod (14, 15) which is connected to the working piston (12, 13) and the two hydraulic travel units (4, 5) being connected to one another mechanically and the two travel cylinders (10, 11) of the two hydraulic travel units (4, 5) being connected to one another hydraulically, and the two travel cylinders (10, 11) of the two hydraulic travel units (4, 5) being acted on simultaneously in alternating directions. The propulsion system (1) according to the invention permits continuous movement of the apparatus to be moved, specifically by virtue of the fact that a third hydraulic travel unit (30) is provided with a travel cylinder (31), a working piston (32) which can be acted on on both sides and a travel rod (33) which is connected to the working piston (32), and the third hydraulic travel unit (30) ... between the two ...
