crane reaches the lower limit, after the time delay 10s arrives, the electromagnet DT13 (19), the electromagnet DT14 (20), the electromagnet DT15 (21), the electromagnet DT16 (22), the electromagnet DT17 (23) and the electromagnet DT18 (24) are disconnected, the frame is put on the empty rubber vehicle, the time delay is 1s to ensure that the frame is put on the empty rubber vehicle, after the time delay 1s arrives, the electromagnet DT23 (15), the electromagnet DT24 (16), the electromagnet DT25 (17) and the electromagnet DT26 (18) are disconnected, the overhead traveling crane ascends, the electromagnet DT3 (9), the electromagnet DT4 (10), the electromagnet DT5 (11) and the electromagnet DT6 (12) are disconnected, loosening the empty rubber vehicle, preparing for pushing out the empty rubber vehicle, after the delay time of 2s is up, attracting the electromagnet DT22 (33), pushing the empty rubber vehicle to separate from the ferry vehicle, detecting the rubber vehicle by the travel switch XK7 (34), indicating that the empty rubber vehicle is pushed away from the ferry vehicle, disconnecting the electromagnet DT22 (33), pushing the rubber vehicle away from the ferry vehicle, disconnecting the electromagnet DT7 (14), releasing the ferry vehicle, reversely rotating the motor M2 (1), returning to the ferry vehicle, resetting the counter C0, detecting the ferry vehicle by the proximity switch JK1 (2), and entering the next cycle;
if the overtravel phenomenon occurs in the movement of the ferry vehicle, the travel switch XK8 (35) and the travel switch XK9 (36) limit the movement range of the ferry vehicle so as to avoid the dangerous situation.
