The "Safety Technical Requirements for Cages" GB 16542 stipulates that "for a cage carrying mine cars, a firm and reliable car arrester must be installed inside the cage body, and the arrester claws shall not open by themselves when arresting the car." The traditional car arrester inside the cage uses the method of manually blocking the side of the mine car; the manual operation is frequent, the labor intensity is high, and there are potential safety hazards, which cannot meet the requirements of mine mechanization and automation.

[0003] Therefore, it is necessary to develop a new type of anti-runaway vehicle device inside the cage specifically to overcome the above problems. Content of the Utility Model

Specific Embodiments

[0019] The technical solution of the utility model will be further described below in conjunction with the drawings and specific embodiments.

[0020] The anti-runaway device in the cage of the utility model includes a device body 11. The device body 11 includes a first bearing seat 1, a transmission shaft 3, a second bearing seat 5, a coupling 6, a speed reducer 7 and a motor 8 connected in sequence. A spring 2 and a stopper 10 are sleeved on the transmission shaft 3, and a key 4 is arranged in the keyways of the transmission shaft 3 and the stopper 10.

[0021] The spring 2 of the utility model is a helical spring, a disc spring or a rubber spring. The transmission shaft 3 is installed in the shaft holes of the first bearing seat 1 and the second bearing seat 5. One end of the coupling 6 is connected to the transmission shaft 3, and the other end is connected to the output shaft of the speed reducer 7. The input shaft of the speed reducer 7 is connected to the output shaft of the motor 8. The device body 11 is installed on the side wall of the cage 12 through a bottom plate 9. The stopper 10 corresponds to the mine car 13 in the cage 12. The stoppers 10 are arranged in pairs in the cage 12.

[0022] During use, when the stopper 10 is closed, the mine car 13 impacts the stopper 10, and the impact force is transmitted to the spring 2 through the stopper 10 to achieve the buffering function. The stopper 10 functions to prevent the car from running away. The motor 8 rotates, drives the stopper 10 to rotate through the reducer 7, coupling 6, transmission shaft 3, and key 4, and the stopper 10 opens to achieve the function of releasing the car. The reducer 7 plays a role in decelerating to make the rotation speed of the stopper 10 meet the requirements of the working conditions. The key 4 plays a role in transmission and anti-rotation to prevent circumferential relative rotation between the stopper 10 and the transmission shaft 3. The key 4 can also be replaced with screws, bolts, etc. The anti-runaway device is installed on the side wall of the cage 12 through the bottom plate 9, and the anti-runaway devices in the cage 12 must be used in pairs.
