ELECTROHYDRAULIC CONTROL DEVICE

摘要

FIELD: mine roof supports for step-by-step movement, particularly hydraulic or pneumatic features thereof. ^ SUBSTANCE: control device comprises valve block and executive mechanisms installed in the block. The executive mechanisms are united in several groups and are electrically activated. The executive mechanisms switch-on hydraulic valve members of several distribution valves. Device also has communication panel including electric and/or electronic circuit. All executive mechanisms are linked to the electric and/or electronic circuit through plug-in connections. The commutation panel is fastened to control device and installed on case-shaped body section detachably connected to the valve block. Plug-in connection members are arranged inside the case. Plug-in connection member pattern corresponds to executive mechanism location on valve block. ^ EFFECT: increased reliability and decreased time for executive mechanisms of distribution valve connection. ^ 18 cl, 4 dwg
