[0002] Mine cars, flatbed trucks, and other vehicles are the main tools for transporting materials underground in coal mines. Due to the unevenness of underground transportation tracks, vehicle transportation involves a series of processes such as uphill and downhill, stopping and running, arranging and connecting in series. During these processes, the vehicle needs to be stopped and stabilized before continuing to the next work process. This is the most difficult part of underground transportation work and the one that is most likely to cause the vehicle to slip or fly away. More than 80% of transportation accidents are caused by improper blocking methods. The choice of blocking methods and blocking devices determines the safety and reliability of underground transportation. In mine production, when the mine car runs to the mine wellhead and other locations, it needs to be stopped. This is generally achieved by installing a car blocker at the corresponding location.

[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a car stopper for a mine transport vehicle, comprising a car stopper seat 1 and a rail 12, and adjustment grooves 11 are symmetrically provided on both sides of the lower surface of the car stopper seat 1, and the adjusting groove 11 on the bottom side of the car stopper seat 1 is slidably connected to the upper end of the rail 12; a first car stop mechanism: used to stop the transport vehicle, the first car stop mechanism includes a two-way screw rod 16, a first car stop block 13 is provided on the inner side of the adjusting groove 11, the first car stop block 13 is movably connected to the upper end of the rail 12, a slide groove 14 is provided on the top inner wall of the adjusting groove 11, and a slider 15 is slidably connected to the inner side of the slide groove 14, and the slider 15 is placed on one end inside the adjusting groove 11 and fixedly connected to the top of the first car stop block 13, the two-way screw rod 16 horizontally penetrates the middle of the slider 15 and is threadedly connected to the slider 15, the two-way screw rod 16 is rotatably connected to the car stop seat 1 through a bearing, and the two-way screw rod 16 is placed on one end outside the car stop seat 1 and is fixedly installed with a handwheel 17.

[0018] In this technical solution, the adjustment groove 11 on the bottom side of the car blocker 1 is slidably connected to the upper end of the rail 12, so that the use position of the car blocker 1 can be adjusted according to the stopping position of the transport vehicle. The staff rotates the handwheel 17 to drive the bidirectional screw rod 16 to rotate. The two sides of the bidirectional screw rod 16 are threadedly connected to the two groups of sliders 15. During the rotation of the bidirectional screw rod 16, the two groups of sliders 15 can be driven to move relative to each other in the slide groove 14, thereby driving the two groups of first car blocks 13 to move relative to each other and press against the upper ends of the two groups of rails 12, further realizing the fixed connection between the car blocker 1 and the rail 12.

[0019] In this embodiment, the buffer mechanism is used for buffering the transport vehicle. The buffer mechanism includes a vehicle blocking platform 2, which is fixedly mounted in the middle of the bottom side of the vehicle blocking seat 1. First water tanks 21 are symmetrically provided inside both sides of the vehicle blocking platform 2. A first piston 22 is slidably connected inside the first water tank 21. A first connecting rod 23 is fixedly installed in the middle of the front side of the first piston 22. The first connecting rod 23 is placed on one end of the outer side of the vehicle blocking platform 2 and is fixedly mounted with a buffer block 24. A first spring 25 is provided on the side of the buffer block 24 close to the vehicle blocking platform 2. A receiving groove 26 is symmetrically provided on the front side of the vehicle blocking platform 2. The receiving groove 26 matches the size of the buffer block 24. The two ends of the first spring 25 are fixedly connected to the rear side of the buffer block 24 and the inner wall of the receiving groove 26 respectively. The first spring 25 is sleeved on the outer side of the first connecting rod 23.

[0020] In this technical solution, when the transport vehicle approaches the vehicle stop seat 1, it first contacts the buffer block 24, and the first connecting rod 23 can push the first piston 22 to move backward in the first water tank 21. At this time, the buffer block 24 compresses the first spring 25, and the elastic force of the first spring 25 can play a buffering effect. The first spring 25 and the buffer block 24 can be accommodated by the storage groove 26 on the front side of the vehicle stop platform 2. It should be noted that: at this time, the transport vehicle is in contact with the front side of the vehicle stop seat 1.

[0021] In this embodiment, the second vehicle stopping mechanism is used to stop the transport vehicle. The second vehicle stopping mechanism includes a water guide groove 35. Second water grooves 3 are symmetrically provided at the rear ends of both sides of the vehicle stopping platform 2. The rear end of the first water groove 21 is connected to the second water groove 3 through the water guide groove 35. The interior of the second water groove 3 is slidably connected with a second piston 31. The second piston 31 is horizontally fixedly installed with a second connecting rod 32 on the middle part of the side away from the water guide groove 35. The second connecting rod 32 is placed on the outer side of the vehicle stopping platform 2 and is fixedly installed with a second vehicle blocking block 33. The second vehicle blocking block 33 is movably connected to the outer side of the rail 12. A second spring 34 is provided on the side of the second piston 31 away from the water guide groove 35. The second spring 34 is sleeved on the outer side of the second connecting rod 32. The two ends of the second spring 34 are respectively fixedly connected to the inner wall of the second water groove 3 and the outer side of the second piston 31. The sizes of the first water groove 21 and the second water groove 3 match.

[0022] In this technical solution, when the transport vehicle pushes the buffer block 24 to compress the first spring 25, the first connecting rod 23 pushes the first piston 22 to move through the water guide groove 35, which can press the water in the first water groove 21 into the second water groove 3. As the amount of water in the second water groove 3 increases, the combination of the second piston 31 and the second connecting rod 32 can push the two groups of second vehicle blocking blocks 33 to move in the opposite direction and press against the outside of the rail 12, further improving the vehicle blocking effect.

[0023] When a car blocker is used for a mine transport vehicle, the adjustment groove 11 on the bottom side of the car block seat 1 is slidably connected to the upper end of the rail 12, and the use position of the car block seat 1 can be adjusted according to the stopping position of the transport vehicle. The staff rotates the handwheel 17 to drive the bidirectional screw rod 16 to rotate, and the two sides of the bidirectional screw rod 16 are threadedly connected to the two sets of sliders 15. During the rotation of the bidirectional screw rod 16, the two sets of sliders 15 can be driven to move relative to each other in the slide groove 14, thereby driving the two sets of first car block blocks 13 to move relative to each other and press against the upper ends of the two sets of rails 12, further realizing the fixed connection between the car block seat 1 and the rail 12. When the transport vehicle approaches the car block seat 1, it first contacts the buffer block 24, and can be pushed through the first connecting rod 23. The first piston 22 moves backward in the first water trough 21. At this time, the buffer block 24 compresses the first spring 25. The elastic force of the first spring 25 can play a buffering effect. At the same time, the water in the first water trough 21 can be pressed into the second water trough 3 through the water guide groove 35. As the amount of water in the second water trough 3 increases, the combination of the second piston 31 and the second connecting rod 32 can push the two groups of second vehicle blocking blocks 33 to move in the opposite direction and press against the outside of the rail 12, further improving the vehicle blocking effect. When the transport vehicle is separated from the vehicle blocking seat 1, the elastic force of the first spring 25 and the second spring 34 can push the buffer block 24 and the second piston 31 to reset, and further guide the water in the second water trough 3 back to the first water trough 21.
