This makes collisions more likely when different cars are on the same track. This is especially true when traveling downhill or around a curve. Uncontrolled speed can lead to collisions and derailment. Accidents caused by derailments require manpower to resolve, which is time-consuming and disrupts production. Utility Model Content

The compression spring 21 is sleeved on the outer surface of the slide rod 19, and the piston 20 squeezes the compression spring 21 when it moves inward.

[0022] Among them, the blocking mechanism includes a push head housing 4, an inclined wedge block 5, an extrusion groove 6, a push rod 7, a telescopic rod 8, a connecting rod 9, a tension spring 10, a guide rail 11, a collision bar 12, a pulley set 13, a guide groove 14 and a connecting plate 22. The inclined wedge block 5 is respectively arranged in the extrusion groove 6 at the left and right ends of the push head housing 4, one end of the push rod 7 is connected to the inclined wedge block 5, the narrower end of the inclined wedge block 5 is arranged on the side close to the cylinder body 15, and the wider end of the inclined wedge block 5 is arranged on the side away from the cylinder body 15. The push rod 7 is laterally slidably connected between the push head housing 4 and the extrusion groove 6 The push rod 7 passes through the push head housing 4 and is rotatably connected to the connecting rod 9 and the telescopic rod 8 through a rotating pin. The end of the connecting rod 9 is connected to the connecting plate 22; the tension spring 10 is sleeved on the push rod 7, and the front and rear sides of the connecting plate 22 are connected with sliders and are slidably connected in the guide rail 11.

[0023] Working principle: When the mine car body 1 slides to the front of the blocking mechanism, the baffle 2 contacts the front end of the collision bar 12 of the blocking mechanism. When the mine car body 1 continues to move along the track 3, it pushes the blocking mechanism to move on the slide rail 17. The blocking mechanism drives the slide rod 19 to slide in the cylinder 15. At this time, due to the piston 20, the compression spring 21 is compressed. The compression spring 21 exerts a reaction force on the mine car body 1, causing the mine car body 1 to brake and decelerate. When the push head shell 4 is pushed to the left end opening of the cylinder 15, due to the inclined design of the inclined wedge block 5, the shorter side of the inclined wedge block 5 enters the left end of the cylinder 15 first. At the outer edge, when the impact bar 12 enters the slide groove 16, the inclined wedge block 5 slides toward the inside of the push head shell 4 through the extrusion groove 6. At this time, the inclined wedge block 5 drives the push rod 7, the telescopic rod 8, and the connecting rod 9 to be squeezed inward, and the connecting plate 22 moves downward under the action of the connecting rod 9. The impact bar 12 moves downward under the sliding assistance of the pulley group 13, releasing the limit of the baffle 2 on the mine car body 1. When the mine car body 1 passes, the elastic recovery of the compression spring 21 pushes the push head shell 4 out, and the inclined wedge block 5 returns to its initial state under the action of the tension spring 10 and the connecting rod 9, and decelerates and brakes the next mine car.

[0024] To sum up: the self-sliding mine car deceleration device of the present invention, through the baffle 2 at the lower end of the mine car body 1 contacts the front end of the collision bar 12 of the blocking mechanism, the mine car body 1 pushes the blocking mechanism to move forward, and the compression spring 21 exerts a reaction force on the mine car body 1, so that the mine car body 1 is braked and decelerated, and the blocking mechanism enters the open end of the cylinder 15 to release the limit of the blocking mechanism, and the blocking mechanism is automatically reset. The deceleration is carried out by this device so as to achieve a better braking and deceleration effect for the mine car and prevent it from falling off the track when turning and crossing the aisle, thereby avoiding safety accidents.
