Description

A road protection device

technical field

The utility model relates to the technical field of road safety protection, in particular to a road protection device.

Background technique

Guardrails are usually arranged on both sides of the existing highway to prevent vehicles from running out of the road accidentally and pedestrians from entering the lane by mistake. Existing highway guardrails are usually simple steel column structures. Once the vehicle collides with the guardrail, it will cause significant damage to the vehicle, and may injure the driver and passengers in the car. The loss of the vehicle is relatively serious. In recent years, there have also been roller-type guardrails, which use flexible rollers to offset the collision force of vehicles, thereby reducing the loss of vehicles. However, it is necessary to install the roller between the upper and lower guardrails. Specifically, the connecting rod passes through the upper and lower guardrails and is connected to the upper and lower guardrails, and then the roller is installed in the middle of the connecting rod. This installation method It is more cumbersome, inconvenient to disassemble, and more troublesome to replace after damage.

Therefore, there is a need for a road protection device, which can not only buffer the collision force of the vehicle, reduce casualties and economic losses caused to the vehicle due to collision with the protective barrier, but also be easy to install and maintain.

Utility model content

The purpose of the invention of the utility model is to provide a road protection device for the problems in the prior art that the steel column guardrail cannot buffer the collision force of the vehicle and the installation of the roller guardrail is inconvenient.

A road protection device, comprising a vertical central rod covered with a layer of anti-collision material, both ends of the vertical central rod are provided with horizontal connecting rods, and the upper and lower horizontal connecting rods Installed on the original guardrail respectively.

This device can be directly installed on the original guardrail without destroying the structure and strength of the original guardrail, and the protective device faces the side of the road. Once the vehicle collides with the guardrail, the anti-collision material layer on the device can prevent the collision of the vehicle. The force plays a better buffering role, which can reduce the loss of the vehicle and ensure the safety of the driver and passengers. The device has simple structure and low cost, can greatly improve the anti-collision function of the guardrail without destroying or changing the existing guardrail, and ensures the safety of people's life and property.

As a preferred solution of the present utility model, the transverse connecting rod is detachably installed on the original guardrail without destroying or changing the structure of the existing guardrail, and is easy to install and disassemble, and is convenient for maintenance and replacement.

As a preferred solution of the utility model, the transverse connecting rod is detachably installed on the original guardrail through a clamp, and the connection with the original guardrail can be realized conveniently through the clamp, and the disassembly is convenient.

As a preferred solution of the present utility model, an air pressure rod is also provided on the transverse connecting rod. When the car hits the guardrail, the air pressure rod will be compressed due to the pressure, and will rebound slowly after being compressed to a certain extent, so as to further buffer the vehicle collision force and reduce the impact of the collision force on the guardrail .

As a preferred solution of the present invention, the anti-collision material layer is a sponge or a foam or a rubber structural member. The anti-collision material on the existing market is suitable for this device, and the most suitable anti-collision material can be selected according to the actual situation.

As a preferred solution of the present invention, the anti-collision material layer is a circular cylindrical structure, and is fitted on the vertical central rod, which is convenient for processing and installation.

As a preferred solution of the utility model, the height of the vertical central rod is greater than 3/4 of the height of the original guardrail, ensuring that the device can cover most of the area of the original guardrail and play a buffering role.

As a preferred solution of the present utility model, the coverage area of the anti-collision material layer is greater than 3/4 of the side area of the vertical central rod, so as to ensure that the anti-collision material layer can cover most of the area of the device, that is, it can cover the Most of the area of the original guardrail ensures the realization of the anti-collision function of the whole device.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

1. This device can be directly installed on the original guardrail without damaging the structure and strength of the original guardrail, and the protective device faces the side of the road. Once the vehicle collides with the guardrail, the anti-collision material layer on the device can protect the vehicle The collision force plays a better buffering role, which can reduce the loss of the vehicle and ensure the safety of the driver and passengers. The device has the advantages of simple structure, low cost and convenient installation, and can greatly improve the anti-collision function of the guardrail without destroying or changing the existing guardrail, so as to ensure the safety of people's life and property.

2. The device is detachably installed on the original guardrail without damaging the structure and strength of the original guardrail. It is easy to install and disassemble, and is convenient for maintenance and replacement.

3. The horizontal connecting rod of the device is also equipped with an air pressure rod. When the car hits the guardrail, the air pressure rod will be compressed due to pressure, and will rebound slowly after being compressed to a certain extent, so that it can further It can buffer the collision force of the vehicle and reduce the impact of the collision force on the guardrail.
