Description

Road anti-collision guardrail

Technical Field

The utility model relates to a road protector technical field, in particular to highway crash barrier.

Background

The highway anti-collision guardrails are arranged on two sides of a road, so that the phenomenon that vehicles rush out of the road due to sudden accidents in the driving process is reduced, and the risk of the sudden accidents is reduced. At present highway crash barrier all generally adopts ripple crash barrier, and the vehicle has more serious damage after striking crash barrier to can bring serious safety problem. The anti-collision guardrail needs to be replaced after receiving the collision to ensure the driving safety of vehicles on the road, and the disposable anti-collision guardrail not only causes the waste of a plurality of public resources, but also has the safety problem possibly causing other vehicles if the anti-collision guardrail is not replaced in time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a highway anticollision barrier to reduce the risk that the car went, and at the damaged degree of the reduction anticollision barrier of certain degree, improve its reuse rate.

The utility model provides a highway anticollision barrier, includes a plurality of stands, and every two are adjacent from the top down has laid anticollision railing and lower anticollision railing in proper order transverse interval between the stand, upward the interval has set up a plurality of buffer blocks in proper order between anticollision railing and the lower anticollision railing, every all be provided with the anticollision barrier piece on the buffer block, the anticollision barrier piece includes flat board, last supporting spring and bottom suspension spring, go up supporting spring with bottom suspension spring's one end is all connected on the buffer block, the other end is all connected on the flat board, the dull and stereotyped outside is equipped with the zigzag buffer block, and the inboard is equipped with the cuboid buffer block, just the cuboid buffer block is located go up supporting spring with between the bottom suspension spring.

Preferably, the materials of the sawtooth-shaped buffer block and the cuboid buffer block are both rubber.

Preferably, the zigzag buffer block with the cuboid buffer block all through the nut with it is fixed dull and stereotyped.

Preferably, the outer surface of the zigzag buffer block is provided with reflective paint.

Preferably, the flat plate is arranged perpendicular to the ground.

The utility model has the advantages that:

when the car hit collision barrier, it at first can contact the anticollision barrier piece, when the striking dynamics is less and medium, the energy of striking can be absorbed by supporting spring and cuboid buffer block respectively, and the anticollision barrier can use repeatedly under this condition. And when the impact force exceeds the accommodating limit of the supporting spring and the cuboid buffer block, the buffer sheet can be irreversibly deformed to further absorb the impact energy. The anti-collision guardrail can increase the repeated use times without influencing the protection effect of the anti-collision guardrail on subsequent vehicles when the collision force is small and medium, and has triple protection of the supporting spring, the cuboid buffer block and the buffer sheet when the collision force is large, so that the driving safety of the vehicles on the road is fully ensured.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "inside", "outside", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The utility model provides a highway crash barrier, specifically as shown in figure 1-2, includes a plurality of stands 1, and every two are adjacent from the top down has laid anticollision railing 2 and lower anticollision railing 3 in proper order horizontal interval between the stand 1, it has set up a plurality of buffer blocks 4, every to go up in proper order the interval between anticollision railing 2 and the lower anticollision railing 3 all be provided with anticollision railing 5 on the buffer block 4, anticollision railing 5 all includes flat 6, goes up supporting spring 7 and bottom suspension spring 8, go up supporting spring 7 with bottom suspension spring 8's one end is all connected on the buffer block 4, the other end is all connected on flat 6, flat 6's the outside is equipped with zigzag buffer block 9, and the inboard is equipped with cuboid buffer block 10, just cuboid buffer block 10 is located go up supporting spring 7 with between the bottom suspension spring 8.

The utility model discloses in, the material of zigzag buffer block 9 and cuboid buffer block 10 is rubber, reduces the striking to the damage of vehicle and highway crash barrier.

The outer surface of the sawtooth-shaped buffer block 9 is provided with reflective paint to attract the attention of people and reduce the probability of traffic accidents.

The flat plate 6 is arranged perpendicular to the ground to ensure the best protection effect.

The utility model discloses a highway crash barrier, when the car striking crash barrier, the car can strike at first crash barrier piece 5, and crash barrier piece 5 can send the impact force at first to zigzag buffer block 9, reduces impact force once. The impact force is then transmitted to the upper support spring 7 and the lower support spring 8, and the impact force is secondarily absorbed. After the upper support spring 7 and the lower support spring 8 contract to a certain extent, the rectangular parallelepiped buffer block 10 performs the third absorption of the impact force. When the impact force exceeds a certain level, the cushion sheet 4 starts to deform, and the impact force is absorbed for the fourth time.

This anticollision barrier has realized the multistage absorption of impact force through zigzag buffer block 9, last supporting spring 7 and bottom suspension spring 8, cuboid buffer block 10 and buffer piece 4, and when buffer piece 4 did not take place serious deformation in addition, the harm that vehicle and anticollision barrier received all by very big reduction, has solved the non-absorbing problem of anticollision barrier, and anticollision barrier's reusability has obtained the promotion.

To sum up, the utility model discloses anticollision barrier, the security that promotes the vehicle and travel that can be very big to can also promote anticollision barrier's reuse nature, reduce its impact to the vehicle, realize the promotion to current anticollision barrier performance.

The above disclosure is only for the specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes that can be considered by those skilled in the art should fall into the protection scope of the present invention.
