Road safety buffering guardrail device

Abstract

The invention provides a road safety buffering guardrail device. The device comprises stand columns, cross beams and buffer steel ropes, the cross beams are fixed to the stand columns, and the stand columns are connected with the cross beams through buffer supports; one side of each buffer support is connected with the corresponding stand column through bolts, and the other side of each buffer support is connected with the corresponding cross beam through buckles; the buffer steel ropes are connected between every two adjacent cross beams, and the two ends of each buffer steel rope are connected with the cross beams through buffers respectively. The buffer supports are arranged between the stand columns and the cross beams, so that the hard collision between a vehicle and a guardrail is reduced; when the vehicle impacts on the buffer steel ropes, the buffer steel ropes can be buffered, the impact force is absorbed, the safety of the vehicle and personnel is protected, and the possibility of secondary injury is reduced. The buffers are installed in the middle of the guardrail, the buffers are deformed to absorb impact energy, harm to personnel in the vehicle is reduced, damage in traffic accidents is avoided, and casualties caused by the traffic accidents can be reduced.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a road safety buffer guardrail device. Background technique [0002] In the field of traffic, guardrail devices are generally provided on one or both sides of the road to forcefully isolate vehicles or pedestrians, or to protect vehicles or pedestrians from the road and rush out of the road. [0003] The protection principle of the road guardrail is to use the deformation of the soil foundation, columns and guardrails to absorb energy, force the out-of-control vehicle to change direction and return to the normal form direction, prevent the vehicle from rushing out of the road, protect the vehicle and passengers, and reduce the damage caused by traffic accidents. loss.

Problems solved by technology

[0004] Ordinary steel metal guardrails can only play an isolation role. When vehicles or pedestrians collide with them, although steel metal guardrails are cost-effective, their shock absorption effect is poor and their impact resistance is not strong. Personnel bring loss of life and property safety. When being hit by a vehicle, due to the huge impact force, the steel guardrail and steel plate are easily broken and cannot protect vehicles or pedestrians. Its rigidity is easy to cause deformation of vehicles in traffic accidents. , resulting in a personal accident
