Description

Anti-stumbling trapezoidal anti-blocking block

technical field

The utility model belongs to the technical field of highway anti-collision facilities, in particular to an anti-stumbling trapezoidal anti-blocking block.

Background technique

Wave beam guardrails are usually installed on both sides of the expressway and the central isolation zone. The wave beam guardrail is one of the most important parts of traffic engineering safety facilities. It is a longitudinal energy-absorbing structure. Its function is to absorb vehicle collision energy through self-deformation , so as to change the driving direction of the vehicle, prevent the vehicle from going out of the road or entering the opposite lane, and minimize the damage to the occupants.

The composition of the wave beam guardrail is shown in Figure 1, mainly including: guardrail board 1, column 2 and guardrail anti-blocking block 3; wherein, the guardrail anti-blocking block 3 adopts a hollow hexagonal structure design; the guardrail anti-blocking block 3 is installed on the guardrail board 1 and the column 2 is the load-bearing part between the guardrail 1 and the column 2. Its main function is: when the vehicle collides with the guardrail 1, the guardrail anti-blocking block 3 absorbs the collision energy through deformation and reduces the impact on the collision. The deformation of the column and the roadbed can reduce the injury of the occupants; it can also prevent the front wheels of the vehicle from being blocked at the column 2.

However, the inventor found in the process of carrying out the utility model that the guardrail anti-blocking block with the traditional hexagonal structure design still has the following deficiencies:

(1) The anti-stumbling function of the anti-blocking block of the guardrail is poor. In practical applications, vehicles, especially passenger cars, often stumble when they collide with the guardrail, causing serious injuries to the occupants in the car; (2) During a collision, the collision energy absorbed by the anti-blocking block of the guardrail through deformation is limited, which is not conducive to reducing the occupant's injury.

It can be seen that the existing guardrail anti-blocking block has the problem of limited protective function, how to effectively improve the protective function of the guardrail anti-blocking block is of great significance.
