Its root is connected with hook bolt alignment pin, and hook bolt (8) surrounds an axle with hook bolt power assistant spring (7) and gib head sensing buting iron (4)
Line progress is in rotary moving, and with the Unscrew of hook bolt (8), gib head sensing buting iron (4) senses from proximity switch (3) in place is hooked together
Position is moved to hook and reaches a proximity switch (2) sensed position；
E, the judgement processing that empty wagons shunter returns：Empty wagons shunter reaches stroller terminal after the delay of 3-10 seconds, PLC
Controller sends return instruction, and judge hook reach a proximity switch (2), hook together in place proximity switch (3), carry pin and approach in place
Switch (6) on off operating mode, when simultaneously meet hook reach a proximity switch (2) connect, hook together in place proximity switch (3) disconnect,
When proposing pin proximity switch (6) connection in place, it is allowed to which empty wagons shunter returns；
G, empty wagons shunter is back to the judgement processing of " stroller deceleration " proximity switch position：Empty wagons shunter is back to stroller and subtracted
During fast position, stroller deceleration proximity switch is connected, and signal is sent to PLC, and PLC sends pin instruction, now
Connect hydraulic pressure and fall pin loop, carry pin rod (1) and fall, carry pin sensing buting iron (5) and leave sensed position with carrying pin rod (1), carry pin
Proximity switch (6) disconnects in place, and latch-locking (11) falls after rise naturally, and hook bolt (8) is in open mode, and latch-locking (11), which falls, is locking
The top of pin-and-hole, it is ready to pick up the connection of locking hook bolt (8) touching hook next time, the connection of two car hitches is in relaxed state；
H, the judgement processing that empty wagons shunter returns from stroller deceleration position：After empty wagons shunter falls pin, hook reaches position and hooked together
Signal is correct in place, shows that empty wagons shunter and permutation empty wagons are kept completely separate, and empty wagons shunter PLC, which is sent, to be continued to return
Instruction；Empty wagons shunter is back to starting point, returns to step a, completes one cycle.
