[0022] The utility model provides a kind of unmanned unhooking and hooking device of rotary connection of mine electric locomotive and mine car, the device realizes the automatic unhooking and hooking of mine electric locomotive and mine car, solves the problem that mine electric locomotive needs to turn around and run when running to unloading station;And unmanned, intelligent, it is the key technology of mine electric locomotive unmanned.

[0023] Working principle:

[0024] First step, when mine electric locomotive 1 receives hooking instruction, slowly run to mine car 2 direction, connector 8 of mine car 2 is inserted into the head of mine electric locomotive 1 and meets head 5, unhooking and hooking device 6 pushes down push rod 10 and is connected with connector 8, after mine electric locomotive 1 hooks, it realizes connection with mine car 2, when receiving unhooking instruction, unhooking and hooking device 6 lifts push rod 10, the head of mine electric locomotive 1 and meets head 5 and is separated from connector 8, and mine electric locomotive 1 realizes separation with mine car 2;

[0025] Second step, when mine electric locomotive 1 reaches predetermined position after arriving at unloading station, gradually reduce running speed and stop running, to avoid impact on unloading station equipment caused by too high speed of mine electric locomotive 1, after background control system detects that the speed of mine electric locomotive 1 is zero and brakes, send unhooking instruction to unhooking and hooking device 6, start unhooking program and automatically unhook;

[0026] Third step, unhooking and hooking device 6 is provided with in-place detection switch 11, after unhooking and hooking device 6 executes unhooking instruction, push rod 10 is lifted upwards, in-place detection switch 11 detects whether push rod 10 is in unhooking position, if push rod 10 is not in unhooking position, start unhooking program again, if unhooking is unsuccessful again, send alarm information to background control system, if push rod 10 is in unhooking position, complete automatic unhooking program, background control system sends unhooking completion signal to mine electric locomotive 1, after mine electric locomotive 1 receives unhooking completion signal, mine electric locomotive 1 starts to separate from mine car 2, and rounds to the rear of mine car 2 to prepare for hooking;

[0027] Fourth step, after mine electric locomotive 1 receives automatic hooking instruction, mine electric locomotive 1 runs at a speed of 2.5 m / s to a position 25 m away from the tail of mine car 2, and then slows down, mine electric locomotive 1 detects the distance between mine electric locomotive 1 and the tail of mine car 2 in real time through position positioning and laser radar 12, and crawls at a speed of 0.5 m / s to approach the tail of mine car 2, when the distance between unhooking and hooking device 6 and the tail of mine car 2 is 0.5 m, slow down to a speed of 0.2 m / s to approach mine car 2, at this time, connector 8 of mine car 2 is inserted into the head of mine electric locomotive 1 and meets head 5, the hollow part of head and meets head 5 coincides with the hollow part of connector 8, when the distance between mine electric locomotive 1 and mine car 2 meets the hooking condition, mine electric locomotive 1 immediately stops running, and starts hooking program to automatically hook.

[0028] The fifth step, after the hooking device 6 executes the hooking instruction, the push rod 10 is inserted into the hollow part of the car head 5 and the hollow part of the connector 8, connecting the mine electric locomotive 1 and the mine car 2, and the in-place detection switch 11 detects whether the push rod 10 is in the hooking position. If the push rod 10 is not in the hooking position, the hooking program is started again, and if the hooking is unsuccessful again, an alarm information is sent to the background control system. If the push rod 10 is in the hooking position, the automatic hooking program is completed, the background control system sends a hooking completion signal to the mine electric locomotive 1, and the mine electric locomotive 1 receives the hooking completion signal and waits for the start of the unloading program.

[0029] The sixth step, when the hooking device 6 hooks, the push rod 10 is quickly inserted into the car head 5 by 10 cm to realize stable connection. The hooking device 6 provides two position distance signals between the mine electric locomotive 1 and the mine car 2, the push rod 10 up and down position signal, the push rod 10 insertion blocked signal, the push rod 10 insertion smooth signal, the push rod 10 pull-out blocked degree signal, and the push rod 10 pull-out success signal. The hooking device 6 has the function of continuously and accurately measuring the distance between the mine electric locomotive 1 and the mine car 2, so that the mine electric locomotive 1 can approach the mine car 2 at low speed, and the front and rear peristalsis, and the intelligent judgment of the mine electric locomotive 1 load, etc. to provide good conditions for automatic hooking.

[0030] The seventh step, the mine electric locomotive 1 realizes inertialess stop by adopting S-shaped curve deceleration to relieve the acting force between the mine electric locomotive 1 and the mine car head 7. When the mine electric locomotive 1 control system detects that the speed is equal to zero and the mine electric locomotive 1 itself is in a stopped state, the hooking device 6 sends a hooking instruction to the hooking device 6, and the hooking device 6 executes the hooking action, and then sends a hooking completion information to the mine electric locomotive 1 control system. In the process of executing the hooking, the mine electric locomotive 1 is in a zero-speed electric brake running state, and is always in a close state with the mine car 2. After receiving the hooking instruction, the hooking device 6 immediately executes the hooking action. In the process of unhooking, the hooking device 6 can diagnose that the mine car 2 hooking pin hole is not aligned through the intelligent controller, and sends a cooperation hooking action request signal to the mine electric locomotive 1. The mine electric locomotive and the mine car rotary connection unmanned hooking device realizes automatic hooking of the mine electric locomotive 1 and the mine car 2, solves the problem of needing to turn around during operation of the mine electric locomotive 1 at the unloading station, realizes unmanned and intelligent hooking of the mine electric locomotive 1 and the mine car 2, and is a key technology for unmanned operation of the mine electric locomotive 1.

[0031] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived from it are still within the protection scope of the utility model.
