Description

Technical Field

[0001] The utility model relates to the technical field of beam guardrail repair, in particular to a repair device for highway corrugated beam guardrails. Background Art

[0002] The corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central dividing strip of the highway. The guardrail consists of two corrugated steel guardrail plates and two columns fixedly clamped between the two corrugated steel guardrail plates. The two columns are fixedly clamped between the two corrugated steel guardrail plates. When the highway is in normal operation, the guardrail can be easily inserted into the pre-set plug-in holes at the opening using the plug-in columns, which plays an isolation and protection role. At the same time, it echoes the guardrail belt on the outside of the highway, which is neat, uniform, and beautiful. When a vehicle collides with it, the corrugated steel guardrail plate has good collision resistance and energy absorption, so it is not easy to be destroyed, and at the same time it can provide good protection for the vehicle and the driver and passengers.

[0003] When a car accident occurs on the road, the impact force of the car will cause the corrugated guardrail to bend, so the bent corrugated guardrail needs to be repaired. There are still certain shortcomings in the repair. The existing guardrail repair device can only straighten the guardrail to restore the bent guardrail to its original straight shape. However, since the guardrail has been subjected to a strong collision, plastic deformation has occurred, and the stress at the bend is very concentrated. The original elasticity of the guardrail steel cannot be restored by general straightening alone. When it is hit again, it cannot provide good buffering and is more prone to breakage.
