The anti-slip device hydraulic cylinder 53 is a double-headed hydraulic cylinder, and the end portions of two piston rods of the anti-slip device hydraulic cylinder 53 are rotatably connected to the anti-slip device rotating rod 52, respectively. The two piston rods of the hydraulic cylinder 53 of the anti-slip device can perform synchronous telescopic motion and can also work independently.
The anti-slip device rotating rod 52 has a circular arc structure, and the center of the circular arc is located on one side of the anti-slip device hydraulic cylinder 53. The number of the anti-slide device rotating rods 52 is four, and two anti-slide device rotating rods are respectively positioned at two ends of the anti-slide device rotating rods 52. The slide preventer turn levers 52 located on both sides of the slide preventer hydraulic cylinder 53 are connected to the end portions of the slide preventer turn levers 52, respectively, and the other end of the slide preventer turn lever 52 is connected to the end portion of the piston rod of the slide preventer hydraulic cylinder 53.

At the next time of approaching the switch 7, the detection device detects whether the approaching switch 7 still has signals, if the signals are kept to indicate that the action of the driving part 3 is invalid, a control room safety warning is submitted. If the signal disappears, which means that the drive part 3 has successfully moved the braking rail 2 along the track 1, the command continues to be executed. After 10 seconds, the driving device 3 reaches a braking position, the driving part 3 stops operating, a piston rod of the anti-slide hydraulic cylinder 53 contracts inwards, the anti-slide cross rod 51 is pushed to approach the rails 1 at two sides, and the braking rail 2 is pushed to be connected with the rails 1 so as to brake the train. The proximity switch 7 on the track 1 detects the signal from the sensing plate 6 and prompts the control room to complete. Thereby achieving the braking of the train and finishing the anti-sliding of the train. When the train needs to be released, the piston rod of the anti-slip hydraulic cylinder 56 extends outwards, the anti-slip cross rod 51 moves towards the anti-slip hydraulic cylinder 56, and therefore the brake rail 2 is driven to be far away from the track 1, the whole device reaches a working position of a release position, and the driving portion 3 works to drive the train to move.
