摘要:
A control means for hydraulic self-advancing support units for underground working, comprising at least one electrohydraulic control device comprising an electric circuit for energizing electromagnets which actuate hydraulic valves, a command keyboard connected to the energizing circuit, a display connected to the energizing circuit and two multipole connectors for connecting the control device to respective adjacent devices, the multipole connectors being connected to one another and to the energizing circuit by electric lines inside the control device, characterized in that the energizing circuit is substantially made up of a CPU control sub-assembly, a keyboard and display sub-assembly, and a magnet control sub-assembly, these sub-assemblies being interconnected by a common bus line, the line connection between the plug-in connectors comprises at least one flexible printed circuit board connected by at least one ribbon cross-connection to one of the three sub-assemblies, and the magnet control sub-assembly is connected by electric lines to the electromagnets, which are disposed outside the control device and are incorporated in the hydraulic valves.
