Control desk of a roadway loader in underground operation, with several valves combined in a block and allocated to individual devices of the roadway loader

摘要

The invention relates to a control desk of a roadway loader in underground operation, with several valves combined in a block and allocated to individual devices of the roadway loader. A two-arm pivoted lever is linked to each of the valve bodies. The pivot bearing of the pivoted lever is arranged under a, for example releasable, guide fork preferably fixed to a desk panel. Above the guide fork, a knob serving as a handle is attached to the free end of the lever, the arm of several pivoted levers which extends from the pivot bearing up to the knob being offset. For the purpose of automatically effective locking of the pivoted levers, i.e. locking which does not depend on operation by the driver and which permits simultaneous operation of several pivoted levers and can preferably be installed subsequently, provision is made for the knob (55) of each pivoted lever (15) to be attached to a sleeve (39) which is preloaded in a spring-mounted manner, is guided on a rod (37) and ends in a plate (40) which is guided with the fork (27, 28) and for the base (47) of which a curved recess (31, 32) is provided in both fork prongs (27, 28), and for the offset sections (62, 63) to be arranged below the sleeves (39), several of which can be deflected simultaneously, and above angled portions alpha of the pivoted levers (35) and their pivot bearings (17).
