The system of claim 6, wherein the piston and the igniter are designed to cooperate with the gas generator and the airbag, when the piston moves to contact with the igniter, the igniter ignites, the airbag can be inflated through the gas generator, and the airbag is inflated and expanded, so that the mine car is initially protected when the mine car is about to collide, and preventive protection before arrival of maintenance personnel is realized.
8. The system of claim 1, wherein when the two sets of mine cars are separated from each other by a pin breakage at the joint, the main fixing seat and the auxiliary fixing seat drive the main connecting rod and the auxiliary connecting rod to separate from each other under the action of the mine cars, and further drive the pistons to slide outside the sliding grooves, so that the gas pressure in the negative pressure cavity is reduced, the gas pressure sensor detects the change of the gas pressure in the negative pressure cavity, and the buzzer is controlled to alarm through the cooperation of the data processor, the signal converter and the controller, so as to remind the manager of the pin breakage position, and meanwhile, the controller transmits an alarm signal to an external dispatching management system through the wireless transceiver, so as to alarm the monitoring personnel.
9. The system of claim 1, wherein a protective pad is disposed on a side of the auxiliary fixing seat, and a protective pad is disposed on a side of the main fixing seat.
10. The system according to claim 1, wherein when the two sets of mine cars are in a mutually close position due to pin collapse, the main fixing seat and the auxiliary fixing seat drive the main connecting rod and the auxiliary connecting rod to mutually close under the action of the mine cars, so that the pistons extrude the negative pressure cavity, the gas pressure intensity in the negative pressure cavity is increased, the pressure sensor can detect the intensity change, and the buzzer is controlled to alarm under the cooperation of the data processor, the signal converter and the controller.
