Further, the top and bottom of the pre-bent plate are corrugated.

Further, a vibration sensor is installed inside the pre-bent plate.

Further, the cushioning medium is polyurethane foam.

Further, the bottom of the steel plate at the forefront is inclined.

Compared with the prior art, the technical scheme of the application has the following beneficial effects:

This vehicle limit for height buffer stop, be convenient for install crashproof mechanism through connecting piece and high-strength bolt, also convenient to detach changes or maintains simultaneously, also can improve life simultaneously to can slow down the whole impact force of vehicle when bumping the bridge culvert top, consume bridge construction's impact kinetic energy through crashproof mechanism self compression energy that produces, avoid taking place serious crushing deformation, thereby improve the effect of buffering, improve the protectiveness simultaneously.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the height limiting anti-collision device for a vehicle in the embodiment comprises an anti-collision mechanism 1 arranged on a bridge and culvert 2, wherein the anti-collision mechanism 1 is arranged on the bridge and culvert 2 through a connecting piece 3 and a high-strength bolt 6, the anti-collision mechanism 1 comprises two steel plates 10, a buffer medium 8 is filled in the steel plates 10, the buffer medium 8 is polyurethane foam, a pre-bent plate 9 is fixed between the two steel plates 10, and a positive signal plate 7 and a negative signal plate 7 are arranged on the inner side of the pre-bent plate 9.

In the structure, under the cooperation of connecting piece and high strength bolt, can realize being convenient for dismouting anticollision institution, under anticollision institution's effect simultaneously, can mention the cushioning effect, simultaneously when the dynamics is great, positive negative signal board contacts to can send urgent early warning like bridge maintenance department.

Wherein the bottom of the steel plate 10 at the forefront is inclined. Through its inclined plane, can prevent that the vehicle from being cut the roof when striking, reduce the buffer force simultaneously.

As shown in fig. 1 and 3, the bridge and culvert 2 is provided with a laser detector 5 and a high-definition camera 4. Through laser detector, can advance the early warning vehicle height, take a candid photograph accident scene's information through high definition digtal camera simultaneously.

As shown in fig. 4, the top and bottom of the pre-bent plate 9 are corrugated. The deformation resistance of the pre-bent plate is better increased through the corrugated shape.

Wherein, the inside of the pre-bending plate 9 is provided with a vibration sensor. Meanwhile, the vibration sensor judges whether the device reports information by mistake by detecting the vibration value.

The working principle of the embodiment is as follows:

When the vehicle bumps crashproof mechanism, can effectively absorb collision energy through the polyurethane foam at the initial stage of collision, reduce the collision power, reduce the vehicle damage degree, protect passenger safety, crashproof mechanism's positive negative pole signal plate can be because the collision power contacts each other simultaneously, whether contacts through positive negative pole signal plate, can judge the size of vehicle collision power to judge the accident size, alleviate maintenance department work load. Meanwhile, the vibration sensor judges whether the device gives a false report or not by detecting the vibration value.

When the small scratch accident occurs, the vibration sensor in the pre-bent plate is subjected to impact vibration, a distance between the positive electrode signal plate and the negative electrode signal plate is not in contact, the device can not send signals to a bridge maintenance department, and the high-definition camera can capture information of an accident scene.

When a major ultrahigh impact accident occurs, the vibration sensor in the pre-bent plate is subjected to impact vibration, and meanwhile, the pre-bent plate is deformed, so that the positive electrode signal plate and the negative electrode signal plate are subjected to impact deformation contact, the device can send emergency early warning to a bridge maintenance department while reducing the impact force of a vehicle, and the whole work flow of capturing information of an accident scene through the high-definition camera is finished.

The entire workflow is completed and what is not described in detail in this specification is well known to those skilled in the art.
