As shown in fig. 5, a cavity 222 is provided inside the guide roller 22; a rubber block 223 is fixedly connected inside the cavity 222; when a vehicle impacts the guide roller 22, the rubber block 223 in the cavity 222 of the guide roller 22 buffers the kinetic energy generated by the impact, and the kinetic energy generated when the vehicle impacts the guide roller 22 is reduced, so that rigid impact is not easily generated in the collision between the vehicle and the guide roller 22.
As shown in fig. 3, a pair of first through holes 24 are formed on the side wall of the protection frame 2 close to the baffle 12; a pair of second through holes 121 are arranged on the side wall of the baffle plate 12 close to the protection frame 2; the first rack plate 131 is in sliding fit with the inner side wall of the first through hole 24, and the first rack plate 131 is in sliding fit with the inner side wall of the second through hole 121; when first rack plate 131 slides along straight-bar 13 lateral wall under the drive of straight-gear 36, first rack plate 131 slides along first through-hole 24 lateral wall and second through-hole 121 lateral wall, and the setting of first through-hole 24 and second through-hole 121 carries on spacingly to first rack plate 131 for first rack plate 131's slip is more stable.
The working principle is as follows: firstly, mounting the mounting seat 1 in an embedding groove 41 in a tunnel body 4, and when a vehicle running in the tunnel body 4 accidentally collides against the inner side wall of the tunnel body 4, the vehicle firstly passes through a deceleration strip 43 and is subjected to preliminary deceleration under the action of the deceleration strip 43; when the vehicle laterally impacts the inner side wall of the tunnel body 4, the vehicle firstly impacts the guide roller 22, the rubber block 223 is arranged inside the guide roller 22, and the kinetic energy generated by the impact is buffered through the rubber block 223, so that the kinetic energy generated when the vehicle impacts the guide roller 22 is reduced; when a vehicle impacts the guide roller 22, impact force generated by the impact drives the protection frame 2 to slide towards the inside of the first sliding groove 11, the first spring 23 is extruded in the sliding process of the protection frame 2, and the first spring 23 is compressed and deformed, so that kinetic energy generated by the vehicle impact is converted into elastic potential energy of the first spring 23, the vehicle is buffered, and a driver is protected; when the vehicle laterally impacts the guide roller 22, the vehicle drives the guide roller 22 to rotate, the laterally impacted vehicle is guided by the guide roller 22, so that the wheel of the vehicle close to one side of the protection frame 2 falls into the guide groove 14, when the wheel falls into the guide groove 14, the wheel presses the straight plate 331 to slide downwards, so that the straight plate 331 contacts with the sliding plate 31, under the cooperation of the arc 333 and the inclined surface 311, the straight plate 331 pushes the sliding plate 31 to compress the second spring 34 and slide toward the inside of the second sliding slot 15, the sliding plate 31 drives the second rack plate 35 to slide along the third sliding slot 16 during sliding, the second rack plate 35 is engaged with the spur gear 36, thereby driving the spur gear 36 and the second rotating shaft 32 to rotate, during the rotation of the second spur gear 36, the spur gear 36 drives the first rack plate 131 to slide along the outer side wall of the straight rod 13, the pressing plate 132 at the end of the first rack plate 131 is gradually brought close to the guide roller 22 and presses the guide roller 22; when the pressure plate 132 and the guide roller 22 are pressed against each other, the rubber protrusion 221 and the rubber plate 133 are pressed and deformed, so that the friction force of the contact part of the pressure plate 132 and the guide roller 22 is increased, the guide roller 22 is not easy to rotate, and when the guide roller 22 is blocked to rotate, the friction mode of the contact part of the guide roller 22 and the side wall of the vehicle is changed from rolling friction to sliding friction, so that the friction force of the contact part of the guide roller 22 and the vehicle is increased, the vehicle speed of the vehicle is reduced under the action of the friction force, and the driver strives for time to stop the vehicle; in the process that the straight plate 331 slides downwards, the side wall of the straight plate 331 is gradually far away from the rubber strip 173, when the straight plate 331 and the rubber strip 173 lose contact, the push plate 171 drives the rubber strip 173 to extend out of the fourth sliding groove 17 under the action of the elastic force of the fourth spring 172, so that the rubber strip 173 contacts and extrudes the wheel, the speed of the wheel is reduced through the friction force between the rubber strip 173 and the wheel, the vehicle is further decelerated, and the base plate 18 arranged at the bottom of the guide groove 14 is used for supporting the straight plate 331, so that the third spring 332 is protected; when the vehicle is traveling in the tunnel body 4, the light 421 at the bottom of the U-shaped frame 42 illuminates the inside of the tunnel, so that the vehicle traveling in the tunnel has a better sight line, and the safety factor of the traveling vehicle is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
