Detailed description of the invention
Remote control center of the present utility model is arranged at outside mine, and also can be arranged in the electrician room in coal mining mine, wherein pump works, emulsification pumping plant are arranged in coal cutting roadway, are connected to each hydraulic support by pipeline; Hydraulic support gathers at coal-face, and the coal-face of average 100 meters arranges the hydraulic support of about about 60 to 70.Each hydraulic support is arranged unit master control borad, sensor-based system, actuating unit, specifically comprise column pressure sensor, passing stroke sensor, shearer position transducer, unit alarm, hydraulic jack valve, hydraulic stroke passing valve, waterfog head, fuselage control panel.
Fuselage control panel arranges function that control button inputs and comprises and open/stop the work moving frame jack, the work of opening/stopping column hydraulic cylinder, remove and report to the police, open/cut off the water fog spray head water spray etc., be mainly used in controlling the work of single hydraulic support, that the control action performing control centre is occurred that the pole respective hydraulic support of deviation or mistake carries out work correction under most cases, such as to the fine setting moving frame distance and carry out, the warning error occurred is removed etc.
Column pressure sensor is arranged on column hydraulic cylinder, determine whether hydraulic support rises and effectively support top board by the force value detecting column, control centre determines whether to continue the voltage supply of column hydraulic cylinder according to force value, opens to perform or closes hydraulic jack valve.
Pass the distance that stroke sensor moves ahead for detecting hydraulic support main body, and distance value hydraulic support main body moved ahead is supplied to control centre, control centre according to liquid rack body move ahead distance determine whether continue as move frame jack fuel feeding promote hydraulic support main body move ahead, with perform open or close hydraulic stroke pass valve.
Shearer position transducer is arranged in hydraulic support main body, can be infrared ray sensor, also can be travel switch.When coal-winning machine runs to before certain hydraulic support, shearer position transducer provides coal winning machine position information in control centre, and control centre controls waterfog head and sprays water to coal-face, to reduce the dust that coal-winning machine cutting rib causes.
Total alarm and unit alarm convenient at the scene with long-range all can Timeliness coverage miswork hydraulic support by mistake.As hydraulic support breaks down, move in frame process and paused by stone card.
Hydraulic support in the present embodiment and control system illustrate further into:
In order to ensure to cut dark and effective unit advance, the stroke of walking jack is decided to be 860mm.φ 125 upside-down mounting jack taked by walking jack.
The two embedded spray position in place are reserved in hydraulic support top beam front end, for installing waterfog head.
Fuselage control panel arranges scram button, once occur the urgent person or equipment breakdown, operator presses its " scram button " on the fuselage control panel of any one hydraulic support of work plane, and full face all hydraulic support stops auto-action immediately.
Fuselage control panel arranges latch buttons, when certain hydraulic support breaks down, when maybe will repair, rotates the latch buttons of this hydraulic support, this hydraulic support and left and right hydraulic support stop action, so that operating maintenance personnel carry out troubleshooting.
Fuselage control panel is arranged shut-down operation key, the fuselage control panel of every platform hydraulic support is provided with operation stop key (red STOP).In hydraulic support program behavior, when running to certain hydraulic support and needing stopping action, can press this support " STOP " key, the hydraulic support within the scope of this key control stops auto-action.
