Anti-collision road guardrail

Abstract

The invention discloses an anti-collision road guardrail. The anti-collision road guardrail comprises protective barriers and a stand column, wherein the stand column is movably provided with a connecting plate capable of connecting the end parts of two adjacent protective barriers, the connecting plate is arranged on the side, facing a road, of the stand column and can move towards the directionof the stand column, a first elastic buffering mechanism is arranged between the connecting plate and the stand column, the first elastic buffering mechanism can give reverse elastic acting force of the connecting plate when the connecting plate moves towards the stand column, the end parts of the two adjacent protective barriers are correspondingly pivoted at the two ends of the connecting plate,a second elastic buffering mechanism is arranged between the protective barriers and the connecting plate, and the second elastic buffering mechanism can give reverse elastic acting force of the protective barriers when the protective barriers swing towards the outside direction of the road along the pivot joint. The invention has the advantages that the structure is simple, a better buffering effect is provided for the acting force generated when a vehicle is impacted, especially the deflection acting force generated during bending deformation of the protective barriers.

Description

Technical field [0001] The invention relates to an anti-collision road guardrail. Background technique [0002] Road collision guardrail is the most important transportation infrastructure for highways and municipal roads, and it plays an important role in the development of the national economy and society. In addition to dividing the road driving area, the road anti-collision barrier allows vehicles to drive in the corresponding area in an orderly manner. When the vehicle is out of control, it can also prevent the vehicle from rushing out of the road, avoiding more serious damage to life and property . The traditional road crash barrier mainly relies on its material itself to withstand the impact of vehicles, the effect is poor, and it cannot play a substantial protective role. CN106638389B discloses a road protection fence with a buffer structure, which includes a protection railing and a column. The adjacent protective railings are fixedly connected by a connecting plate.

AI Technical Summary

Problems solved by technology

However, there are certain defects in this patented technical solution: when the protective railing is hit by a vehicle, especially when the vehicle hits the middle area of ​​the protective railing, the middle area of ​​the protective railing will be the first to appear bending deformation, resulting in the two ends of the protective railing. A deflection movement occurs between the columns and a deflection force is generated. The buffer structure of the above-mentioned patented technology has a certain buffering effect on the impact force that goes straight to the outside of the road, but the buffering effect on this deflection force is relatively poor.
