[0027] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0028] The application provides a wind door 2 vehicle stopping system, comprising a wind door 2 and a track 1 arranged on a roadway, the wind door 2 is arranged on the track 1, and further comprising:
[0029] A vehicle stopping assembly 3 is arranged on the track 1, and the vehicle stopping assembly 3 has an open state and a closed state; in the open state, the vehicle stopping assembly 3 closes the track 1, and in the closed state, the vehicle stopping assembly 3 opens the track 1 to pass through a vehicle.
[0030] A buffer deceleration assembly 4 comprises an arc-shaped rod 41, an elastic component 42 and a telescopic component 43; one end of the telescopic component 43 is rotatably arranged on the ground, the telescopic end of the telescopic component 43 is rotatably connected with the arc-shaped rod 41, the telescopic component 43 is telescopic to make the arc-shaped rod 41 away from or close to the track 1, and one end of the elastic component 42 is connected with the arc-shaped rod 41, and the other end of the elastic component 42 is rotatably arranged on the ground.
[0031] The wind door 2 is arranged on the track 1 on the roadway, and is used for controlling air flow and vehicle passing.
[0032] The wind door 2 vehicle stopping system of the embodiment of the application can decelerate and stop the vehicle, and improve the service life of the vehicle stopping device.
[0033] Specifically, the buffer deceleration assembly 4 is arranged on the track 1 between the wind door 2 and the vehicle stopping assembly 3, so that when the vehicle stopping device closes the track 1, the vehicle first contacts the buffer deceleration assembly 4 and then is stopped on the track 1 by the vehicle stopping assembly 3.
[0034] As shown in Figs. Figure 1 and Figure 2 , the arc-shaped rod 41 extends in the left-right direction, the left end of the arc-shaped rod 41 is located directly above the track 1, the right end of the arc-shaped rod 41 is rotatably arranged on the ground, the elastic component 42 and the telescopic component 43 are telescopic in the front-back direction, the elastic component 42 is rotatably arranged on the ground, the front end of the telescopic component 43 is rotatably arranged on the ground, when the vehicle moves from the front wind door 2 to the vehicle stopping assembly 3, the left end of the arc-shaped rod 41 collides with the vehicle, the arc-shaped rod 41 rotates and the arc-shaped rod 41 keeps contacting the vehicle during rotation, the elastic component 42 is stretched at this time to buffer the vehicle and absorb the impact energy of the vehicle.
[0035] The air door 2 vehicle stopping system of the embodiment of the present application realizes effective buffering and deceleration of the vehicle, avoids direct impact of the vehicle on the vehicle stopper, and improves the driving safety of the mine.
[0036] In some other embodiments, the elastic component 42 and the arc-shaped rod 41 can be rotatably arranged on the same steel plate, and the telescopic component 43 is arranged on the ground. The telescopic component 43 is telescopic to extend the elastic component 42, the arc-shaped rod 41 and the steel plate in the left-right direction, so that the left end of the arc-shaped rod 41 is directly above the track 1 or the left end of the arc-shaped rod 41 is away from the track 1.
[0037] Further, the telescopic component 43 is detachably connected with the arc-shaped rod 41. For example, when the buffering and deceleration of the vehicle is not needed, the rear end of the telescopic component 43 is rotatably connected with the arc-shaped rod 41. When the buffering and deceleration of the vehicle is needed, the rear end of the telescopic component 43 is disconnected with the arc-shaped rod 41.
[0038] In some embodiments, the buffering and deceleration assembly 4 further comprises a convex component 44 arranged at one end of the arc-shaped rod 41 towards the track 1.
[0039] Specifically, the convex component 44 is arranged at the left end of the arc-shaped rod 41. The arrangement of the convex component 44 facilitates reducing the wear of the vehicle and the buffering component when the vehicle passes through the buffering and deceleration assembly 4. By arranging the convex component 44 at the left end of the arc-shaped rod 41, it can be ensured that the vehicle first contacts the convex component 44 when passing through the buffering and deceleration assembly 4, thereby reducing the direct wear of the arc-shaped rod 41.
[0040] The convex component 44 can be made of wear-resistant materials, such as ultra-high molecular weight polyethylene, polytetrafluoroethylene, polyformaldehyde, and polyketone, to ensure that it can maintain good performance during long-term use.
[0041] In some embodiments, the convex component 44 is at least partially spherical in shape, or the convex component 44 is arc-shaped. The spherical convex component 44 cooperates with the arc-shaped rod 41 and the elastic component 42 when contacting the vehicle, and can automatically adjust the contact angle when the vehicle passes through the buffering and deceleration assembly 4, thereby adapting to the shape and driving track of different vehicle tires and providing better buffering effect. The spherical surface is smooth, which can reduce the friction between the vehicle tire and the convex component 44 and reduce noise. The arc-shaped convex component 44 has a large contact area with the vehicle, which facilitates reducing the pressure between the vehicle and the convex component 44 when the vehicle impacts, reducing wear, and improving the passing stability and safety of the vehicle.
[0042] In some embodiments, the buffer deceleration assembly 4 further includes an energy-absorbing component 45, which includes a bent rod 451 and an energy-absorbing column 452. The energy-absorbing column 452 is fixedly installed on the ground, and the bent rod 451 is installed on the arc-shaped rod 41. The other end of the bent rod 451 extends toward the end away from the arc-shaped rod 41, and the bent rod 451 rotates with the arc-shaped rod 41 to touch or move away from the energy-absorbing column 452.
[0043] Specifically, one end of the bent rod 451 is rotatably connected to the arc-shaped rod 41, and the other end of the bent rod 451 faces the energy-absorbing column 452. The surface of the energy-absorbing column 452 may be fitted with discarded tires to cushion and absorb energy when the bent rod 451 impacts it. Alternatively, the energy-absorbing column 452 itself may consist of multiple tires connected by steel wires and fixed to the ground. When a vehicle passes over the arc-shaped rod 41, the arc-shaped rod 41 rotates under pressure. The bent rod 451 rotates with the arc-shaped rod 41, and its other end rotates to contact the energy-absorbing column 452. The energy-absorbing column 452 absorbs the impact energy of the bent rod 451, achieving cushioning and deceleration.
[0044] It is understandable that when the vehicle collides with the curved bar 41, there is a preset distance between the curved bar 451 and the energy-absorbing column 452, so that the curved bar 41 will only collide with the energy-absorbing column 452 after rotating at a certain angle.
[0045] In some embodiments, the energy-absorbing component 45 further includes an energy-absorbing plate 453, which is disposed at the end of the bent rod 451 facing the arc-shaped rod 41. The energy-absorbing plate 453 can be rectangular or arc-shaped, and is used to increase the contact area between the bent rod 451 and the energy-absorbing column 452, so as to reduce the impact pressure when the bent rod 451 impacts the energy-absorbing column 452, and improve the stability and lifespan of the energy-absorbing column 452.
[0046] In some embodiments, the number of buffer deceleration components 4 is multiple, and the multiple buffer deceleration components 4 are arranged at intervals along the extension direction of the track 1, and / or, the multiple buffer deceleration components 4 are arranged at intervals relative to each other on both sides of the track 1.
[0047] like Figure 3 As shown, the buffer deceleration components 4 can be arranged at intervals in the extension direction of the track 1, that is, multiple buffer deceleration components 4 can be arranged at intervals in the front-back direction, or multiple buffer deceleration components 4 can also be arranged at intervals in the left-right direction.
[0048] In some embodiments, the braking assembly 3 is disposed between a plurality of buffer deceleration assemblies 4. For example... Figure 3 As shown, multiple buffer deceleration components 4 are arranged symmetrically in mirror image on both the front and rear sides of the vehicle blocking component 3. This allows the buffer deceleration components 4 to buffer the vehicle both when it is moving from front to back and from back to front.
[0049] In some embodiments, the convex head 44 is integrally formed with the arc-shaped rod 41 to improve the stability of the connection between the arc-shaped rod 41 and the convex head 44.
[0050] In some embodiments, the side of the convex head 44 facing the track 1 is smooth to reduce the wear of the convex head 44 during operation. That is, the friction between the contact surface of the convex head 44 and the vehicle is reduced, thereby reducing the wear during operation. The smooth surface makes it easier for the vehicle to pass through the convex head 44, reduces the resistance generated by friction, and improves the smoothness of passing.
[0051] In some embodiments, the telescopic part 43 is a hydraulic telescopic cylinder. The above describes in detail a damper vehicle stopping system provided by the present application. The principles and implementation manners of the present application are described by applying specific examples in this paper, and the above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for those skilled in the art, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
