Embodiment
Be below specific embodiment of the utility model, be now described further by reference to the accompanying drawings.
As shown in Figure 1, a kind of PLC control device of hydraulic haulage shearer, comprise the PLC module for data processing, the input end of described PLC module is connected with coalcutter start button, coalcutter stop button, scraper conveyer latch buttons, overload detection plug-in unit and zero-bit travel switch; The output terminal of described PLC module be connected with coalcutter guide start-up circuit, scraper conveyer guide start-up circuit, for controlling overload solenoid valve that shearer haulage slows down, overload warning light, zero-bit solenoid valve and zero-bit solenoid valve warning light; Described PLC control device also comprises temperature protection plug-in unit.
In the present embodiment, as shown in Figure 2, described overload detects plug-in unit and adopts transformer component.
As shown in Figure 4, described temperature protection plug-in unit comprises the thermistor and temperature protection execution relay that are embedded in motor interior, and the normally opened contact of described temperature protection execution relay is connected in parallel on the two ends of coalcutter stop button.
Described PLC module has the input of 18 switching values and the output switch parameter of 12.
Following table is the PLC address assignment in the present embodiment:
Press coalcutter start button, input relay 001 is connected, and output relay 1000 obtains electric, and coalcutter precursor circuit starts.Press coalcutter stop button, input relay 003 is connected, and internal relay 20000 obtains electric, and the normally closed contact be arranged in starting-up later time disconnects, and coalcutter is out of service.
The external scraper conveyer latch buttons of input relay 004, press scraper conveyer latch buttons, internal relay 20001 obtains electric, normally closed contact disconnects output relay 1001 relay circuit, output relay 1001 dead electricity disconnects scraper conveyer starting-up later time, make scraper conveyer out of service, realize scraper conveyer locking.
As shown in Figure 2, the external overload of input relay 005 detects the normally opened contact of plug-in unit, when power of motor reaches 120% of rated power, normally opened contact closes, input relay 005 is connected, and output relay 1002 obtains electric output, and overload solenoid valve starts, shearer haulage is slowed down, and output relay 1003 obtains the action of electric display overload solenoid valve simultaneously.
As shown in Figure 3, be zero position protection loop of the present utility model.When coalcutter motor disconnector closes a floodgate, the zero-bit closing of contact on zero-bit travel switch on input relay 007, output relay 1006 obtains electric output, and zero-bit solenoid valve starts, output relay 1007 output display zero-bit solenoid valve operating state simultaneously, now coalcutter can not start.When the normally opened contact in zero position protection loop closes, internal relay 20002 obtains electric, and its normally closed contact disconnects zero-bit loop, and zero-bit solenoid valve dead electricity, coalcutter can start.
As shown in Figure 4, the normally opened contact that the temperature protection plug-in unit of coalcutter is controlled by thermistor realizes.The normally opened contact of temperature protection execution relay is connected in parallel on the two ends of coalcutter stop button, and when temperature reaches assigned temperature, normally opened contact closes, and input relay 003 is connected, and internal relay 20000 obtains electric, and coalcutter stops.
