Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and in particular relates to an elastic rotor combined opening guardrail. Background Art

[0002] The openings set up in the central median of the highway provide great convenience for emergency vehicles and maintenance vehicles to pass through the highway, but there is a risk of vehicles running into the opposite lane and causing serious accidents. Therefore, anti-collision guardrails are required at the openings for protection. However, when a collision occurs, the existing guardrails at the openings often cannot effectively absorb and disperse the collision energy, resulting in serious damage to the vehicle and even injuries to the people inside the vehicle. Especially when the vehicle is traveling at high speed, the rigid collision of the traditional opening guardrail will cause the vehicle to instantly bear a huge impact force, increasing the severity of the accident.

[0003] In addition, the maintenance and replacement costs of existing open guardrails are high. Once a collision occurs, part or all of the guardrail needs to be replaced, and the replacement process is cumbersome, affecting traffic. Therefore, there is a need for a guardrail that can effectively absorb and disperse collision energy and reduce maintenance costs. At present, there is an elastic roadside guardrail on the market, which absorbs and disperses collision energy through elastic materials. Although it can reduce the damage to vehicles and personnel to a certain extent, its structure, which mainly relies on elastic materials for protection, is insufficient in stability and protection capabilities, and the guardrail cannot be moved and adjusted according to specific needs when in use.

[0004] Therefore, the guardrails in the prior art have the problems of being unable to effectively absorb and disperse collision energy, having high maintenance costs, and having unstable elastic material properties. There is an urgent need for a new type of guardrail that can effectively solve the above problems. Utility Model Content
