The control method of carbon block stacking overhead travelling crane, specific as follows:
The initial position: the anchor clamps group is on top, and anchor clamps open, electromagnet 7 energisings, and spring 4 is stretched.
Gripping charcoal piece: movable motor 2 operations, the position that runs to the charcoal piece stops, if run to the end of workshop factory building, then No. five switches send to the PLC controller with this signal, the PLC controller receives and sends control command behind this signal and make movable motor 2 outages, if No. five switch 11 is malfunctioning, then the shock absorber of end carriage hits in the end of workshop factory building, to cushion its impact;
Bridge motor 17 energisings, the anchor clamps group descends fast, treat that the anchor clamps contact rigidly connects (Fig. 1) when touching the charcoal piece, No. one switch sends to the PLC controller with detected this signal, and the PLC controller receives this signal and sends the deceleration of control command control anchor clamps group and descends, and treats that anchor clamps descend when putting in place, No. seven switch 14 detects this anchor clamps group run location signal, and detected signal sent to the PLC controller, and the PLC controller receives this signal and sends control command and makes bridge motor 17 outages, and the anchor clamps group is static;
Electromagnet 7 outages, spring 4 pullings, No. three switches 5 detect the run location signal of Rotary hanging hook 8, and detected signal is sent to the PLC controller, and the PLC controller sends 17 energisings of control command control bridge motor after receiving this signal, and the anchor clamps group rises;
Treat that the anchor clamps group rises to certain altitude, No. nine switch 18 detects the signal of anchor clamps group in uppermost position, and detected signal sent to the PLC controller, the PLC controller receives and sends control command behind this signal and make bridge motor 17 outages, the anchor clamps group is static, if No. nine switch 18 is malfunctioning, be that bridge motor 17 still moves, but surpass the revolution of setting, then No. ten switches 20 detect this signal, and the signal that detects sent to the PLC controller, and the PLC controller sends 17 outages of control command control bridge motor after receiving this signal, and the anchor clamps group is static;
Put the charcoal piece: movable motor 2 operations, after putting in place, operation stops, bridge motor 17 energisings, the anchor clamps group descends, after the decline of anchor clamps group puts in place, bridge motor 17 outages, the anchor clamps group is static.If the anchor clamps group rises or the too fast rotating speed that is bridge motor 17 above setting of descending speed, then No. eight switches 16 detect this signal, and the signal that detects sent to the PLC controller, the PLC controller receives and sends control command control bridge motor 17 behind this signal and slow down;
Treat that anchor clamps descend when putting in place, No. seven switch 14 detects this anchor clamps group run location signal, and detected signal is sent to the PLC controller, and the PLC controller receives this signal and sends control command and makes bridge motor 17 outages, and the anchor clamps group is static;
Electromagnet 7 energisings, No. four switches 6 measure the run location signal of Rotary hanging hook 8, and detected signal is sent to the PLC controller, the PLC controller receives and sends control command control behind this signal and send instructions, bridge motor 17 energisings, the anchor clamps group rises, and returns the initial position.
Hoist ceiling crane 12 work, as run to high order end or low order end (so not allowing in the operation), then No. six switches 13 or ride on Bus No. 11 switch 21 detect this signal, and the signal that detects is sent to the PLC controller, and the PLC controller sends control command control hoist ceiling crane 12 " pinning " after receiving this signal.
Safety interlocking: if No. nine switches 18 or No. ten switches 20 do not send instructions, movable motor 2 is in " pinning " state.If No. nine switches 18 or No. ten switches 20 do not send instructions and No. four switches 6 do not send instructions, hoist ceiling crane 12 is in " pinning " state.
