Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision guardrails, in particular to an anti-collision guardrail for transportation. Background Art

[0002] Anti-collision guardrails for transportation are protective facilities installed on both sides or along highway bridges. They are mainly used to prevent vehicles from colliding with the edge of the bridge or falling into the river under the bridge and other dangerous situations. They are usually made of metal materials and use special design and installation methods. They can effectively absorb and disperse collision forces to protect the safety of vehicles and passengers.

[0003] After searching, the Chinese patent application number 202220320595.9 discloses a collision-proof guardrail for transportation, which includes a guardrail body, and the guardrail body includes at least two posts. The posts are provided with a mounting cavity arranged along the height direction of the posts and open at the upper end, and the upper and lower ends of the posts are respectively provided with two post openings communicating with the mounting cavity; a railing frame is provided between two adjacent posts, and the railing frame includes two cross bars evenly distributed along the height direction of the posts, and a plurality of vertical bars are connected between the two cross bars. A connecting plate is provided in the mounting cavity, and both ends of the cross bars are connected to the connecting plate. The utility model makes it possible for road maintenance personnel to replace the entire post when the railing frame on the guardrail body is hit, thereby better improving the maintenance efficiency of the guardrail body, and also better reducing the workload of road maintenance personnel;

[0004] The above patent still has the following deficiencies: (1) The device is prone to rebound impact. When a vehicle collides with the device, the vehicle is easily affected by the rebound impact of the device, which may cause the vehicle to turn around and rush back to the road, causing the vehicle to lose control and easily collide with surrounding vehicles, causing a secondary accident, and may also cause secondary injuries to the occupants of the vehicle, increasing the degree of injury;

[0005] (2) It is not easy to install. When the existing device is installed on a curve, the crossbar is usually manually bent to make it coincide with the edge of the road. This installation method easily causes the crossbar to deform, affecting the anti-collision effect of the crossbar.

[0006] Therefore, a kind of traffic and transportation anti-collision guardrail is needed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to address the problem that the existing devices are prone to rebound impact.
