[0025] The process of separating or connecting the front car 2 and the rear car 3 is as follows: first, the front car stopper 4-1 in the car stopping device 4 is extended upwards to the position of the stop rod above the track 1 to be in the raised car stopping state, the trolley mechanism 5 is moved to the axle of the rear car 3, the two claws 5-4 clamp the axle of the rear car 3, then the trolley mechanism 5 can push the rear car 3 forward, and at the same time, the front car 2 is moved forward along the track 1 to the position of the front car stopper 4-1 and stops, the rear car stopper 4-2 is raised to be in the car stopping state, the front and rear wheels of the front car 2 are clamped by the front car stopper 4-1 and the rear car stopper 4-2, the positions of the front car stopper 4-1 and the rear car stopper 4-2 are fine adjusted, so that the connection between the two cars is located at the appropriate position, at this time, the front car 2 is fixed in the car stopping device 4 and cannot move, and the rear car 3 is clamped between the two claws 5-4 of the trolley mechanism 5 and is also in a fixed state.

[0026] After the two mine cars are in a safe and fixed state, the worker enters the connection between the two mine cars to connect or disconnect the connecting piece. If it is to disconnect the connecting piece, after the connecting piece is disconnected, the car blocking mechanism 4 releases the front mine car 2, and the car pushing mechanism 5 pushes the rear mine car 3 and the front mine car 2 to the positions to be reached, respectively, and the mine car separation process is completed. This process is also applicable to the separation of multiple mine cars. If it is to connect the connecting piece, after the connecting piece is connected, the car blocking mechanism 4 releases the front mine car 2, and the car pushing mechanism 5 only pushes the rear mine car 3 together with the front mine car 2 to the position to be reached, and the mine car connection process is completed. This process is also applicable to the connection of multiple mine cars.
