Safe driving guards for road, bridge or tunnel guardrails

Abstract

The invention relates to a safety driving protection device for guardrails of highways, bridges or tunnels, which comprises a cross bar arranged on the outer side of the guardrail of a curve and protruding outward. The end of the crossbar away from the curve guardrail is provided with a stopper, the lower end of the anti-collision plate is connected with an anti-falling net, and the end of the anti-falling net is far away from the anti-collision plate and is connected with the end of the crossbar close to the curve guardrail. The anti-fall net is opened during the outward movement of the anti-collision plate, because the impact force in the horizontal direction of the vehicle is buffered by the anti-collision plate, so the vehicle rushing out of the curve falls into the anti-fall net under its own gravity , can effectively prevent the vehicle from falling into the cliff, causing loss of life and property, and the invention has the effect of effectively preventing the vehicle from rushing out of the curve and causing a crash accident.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a safety driving protection device for guardrails of roads, bridges or tunnels. Background technique [0002] At present, with the development of society, traffic is becoming more and more important. However, driving safety is an issue that has to be taken seriously. Every year, traffic accidents across the country lead to a large number of casualties and property losses. At the same time, due to the poor visibility at night, the probability of safety accidents at night is significantly higher than that during the day, and traffic accidents are more likely to occur at night on rainy days. [0003] In the prior art, the Chinese patent whose publication number is CN107237282A discloses a safety driving warning device for guardrails of highways, bridges or tunnels. , each guardrail is provided with a set of fixed blocks side by side along the length direction; the two fixed ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: although the invention can play a dynamic warning effect by emitting light from fluorescent powder, the driver does not observe in time on road sections with speed limit requirements, especially at some curved intersections backed by cliffs. Curves, it is easy to cause the car to break through the guardrail and rush out of the curve, causing accidents such as the car falling off the cliff
