A kind of rollback point is the transmission control system circuit at a slow speed; Comprise the duty indicating circuit, just changing a job and making condition indication circuit and just changeing control circuit that the live wire between indicating circuit and the control circuit is provided with electrothermal relay; Also comprise counter-rotating duty indicating circuit and reverse turn control circuit; The duty indicating circuit is just being changed a job and is being made condition indication circuit and just changeing control circuit, and counter-rotating duty indicating circuit and reverse turn control circuit all are connected in parallel in the electric power loop.
The duty indicating circuit is provided with indicator lamp HL0, and the duty indicating circuit is directly parallel in the electric power loop.
Just changing a job and making on the condition indication circuit series connection indicator lamp HL1 and contactor KM1 normally opened contact, and just changing a job and be directly parallel in the electric power loop as condition indication circuit.
Series connection indicator lamp HL2 and contactor KM2 normally opened contact on the counter-rotating duty indicating circuit, and counter-rotating duty indicating circuit is directly parallel in the electric power loop.
Just changeing the invert button SB1 that connects successively on the control circuit, stop button SB3, contactor KM2 normally-closed contact, contactor KM1 coil, just changeing button SB1 two ends parallel connections KM1 normally opened contact, and just changeing control circuit and be directly parallel in the electric power loop.
Connect successively on the reverse turn control circuit invert button SB2, contactor KM1 normally-closed contact, contactor KM2 coil, invert button SB2 two ends parallel connection KM2 normally opened contact, and reverse turn control circuit is directly parallel in the electric power loop.
When the needs normal inching turning, pin and just change button SB1, normally opened contact KM1 is closed; Indicator lamp HL1 is bright, and contactor KM1 coil gets electric, and the machine that conducts electricity is slowly just being transported row; Drive coal pulverizer and just transporting row, when coal pulverizer runs to ideal position, unclamp the SB1 button; Driving motor shuts down at a slow speed, realizes transmission device crawl function at a slow speed.
When the needs reverse inching turning, pin invert button SB2, normally opened contact KM2 is closed; Indicator lamp HL2 is bright, and contactor KM2 coil gets electric, the machine that conducts electricity slowly counter-rotating operation; Drive coal pulverizer counter-rotating operation, when coal pulverizer runs to ideal position, unclamp the SB2 button; Driving motor shuts down at a slow speed, realizes transmission device crawl function at a slow speed.
