AI Technical Summary
Existing car stoppers can only be used on tracked mine cars and cannot effectively limit the movement of mine cars on the floor of trackless roadways, which makes it easy for mine cars to run away.
Design a mine car with a built-in brake. By setting a positioning structure on the mine car, the built-in motor drives the rotating shaft to drive the moving ring and the follower inclined block, so that the contact wheel contacts the ground to increase the friction and achieve the braking effect.
The system effectively prevents mine car runaway accidents by using a built-in car stopper on the bottom slab of the trackless roadway. It increases the contact friction between the mine car and the ground, thus achieving safe stopping.

[0024] The transport structure 2 includes placing frame 201, and the outer side of placing frame 201 is fixedly installed with traction head 202.
[0025] The positioning structure 3 includes drive box 301, the inner wall of drive box 301 is rotatably connected with rotating shaft 303 through built-in motor 302, the surface of rotating shaft 303 movably sleeves moving ring 307, and the bottom of moving ring 307 is fixedly installed with follow-up inclined block 308.
[0026] The inner wall of drive box 301 is slidably connected with lifting plate 309, the top of lifting plate 309 is provided with abutting wheel 310, the bottom of lifting plate 309 is fixedly installed with ground contact plate 312, and ground contact plate 312 extends to the below of drive box 301.
[0027] Specifically, the surface of rotating shaft 303 is fixedly sleeved with gear ring 305, the inner wall of drive box 301 is slidably connected with locking rack 306 through electric push rod, and locking rack 306 is located behind gear ring 305.
[0028] In the embodiment, the electric push rod is started, so that the movable end of the electric push rod drives the locking rack 306 to move towards the gear ring 305, so that the locking rack 306 meshes and locks the gear ring 305, so that the gear ring 305 is locked together with the rotating shaft 303 at this time, so that the ground plate 312 can stably contact the ground.
[0029] Specifically, the surface of the rotating shaft 303 is provided with a closed groove 304 connected in head and tail, and the inner wall of the moving ring 307 is fixedly installed with an insertion rod inside the opening of the closed groove 304.
[0030] In the embodiment, since the surface of the rotating shaft 303 is provided with the closed groove 304 connected in head and tail, the rotation of the rotating shaft 303 drives the opening of the closed groove 304 to rotate synchronously, so that the moving ring 307 slides together with the opening of the closed groove 304 through the insertion rod inside it, so that the moving ring 307 starts to slide along the direction of the rotating shaft 303, so that the moving ring 307 drives the driven inclined block 308 to displace towards the direction of the abutting wheel 310.
[0031] Specifically, the inner wall of the driving box 301 is fixedly installed with a penetrating plate 311, and the top end of the penetrating plate 311 is provided with a damping spring, and the top end of the damping spring is located in the inner wall of the abutting wheel 310 and is elastically connected with the inner wall of the abutting wheel 310.
[0032] In the embodiment, after the abutting wheel 310 is continuously pressed by the driven inclined block 308, the abutting wheel 310 will descend and start to compress the damping spring, so that the relative position between the abutting wheel 310 and the penetrating plate 311 changes, and the abutting wheel 310 and the penetrating plate 311 gradually approach each other;
[0033] When the ground plate 312 needs to rebound, the moving ring 307 drives the driven inclined block 308 to gradually move away from the abutting wheel 310 through the closed groove 304, so that the pressing force of the abutting wheel 310 gradually disappears, so that the damping spring starts to gradually stretch, so that the abutting wheel 310 starts to drive the lifting plate 309 and the ground plate 312 to rebound to the initial position.
[0034] In use, when the mine car needs to be braked, the positioning structure 3 is started, so that the built-in motor 302 in the driving box 301 can drive the rotating shaft 303 to rotate, and since the surface of the rotating shaft 303 is provided with the closed groove 304 connected in head and tail, the rotation of the rotating shaft 303 drives the opening of the closed groove 304 to rotate synchronously, so that the moving ring 307 slides together with the opening of the closed groove 304 through the insertion rod inside it, so that the moving ring 307 starts to slide along the direction of the rotating shaft 303, so that the moving ring 307 drives the driven inclined block 308 to displace towards the direction of the abutting wheel 310;
[0035] When the follow-up inclined block 308 gradually contacts the abutting wheel 310, the abutting wheel 310 is driven to gradually descend by the follow-up inclined block 308, so that the abutting wheel 310 drives the lifting plate 309 to synchronously descend, so that the lifting plate 309 drives the ground-contacting plate 312 to gradually contact the ground, so that the contact between the ground-contacting plate 312 and the ground can increase the contact friction between the mine car and the ground, so that the mine car has a braking effect.
[0036] After the ground-contacting plate 312 contacts the ground, the electric push rod is started, so that the movable end of the electric push rod drives the locking rack 306 to move towards the gear ring 305, so that the locking rack 306 meshes and locks the gear ring 305, so that the gear ring 305 is locked together with the rotating shaft 303 at this time, so that the ground-contacting plate 312 can stably contact the ground.
[0037] In summary, the mine car with the self-contained car stopper is provided with the positioning structure 3, the built-in motor 302 in the driving box 301 can drive the moving ring 307 to drive the follow-up inclined block 308 to displace towards the abutting wheel 310 through the rotating shaft 303, so that the abutting wheel 310 drives the lifting plate 309 to drive the ground-contacting plate 312 to gradually contact the ground under the driving of the follow-up inclined block 308, so that the contact between the ground-contacting plate 312 and the ground can increase the contact friction between the mine car and the ground, so that the mine car has a braking effect, and the mine car is prevented from easily running off the track on the floor of the trackless roadway.
