Abstract

The invention discloses a road safety guardrail, comprising a base fixedly connected to a road substrate, wherein a rotational universal ball bearing is installed on the base, and the universal ball bearing is rigidly connected to the bottom ends of upright posts; a pulley rotated around the upright posts is installed on the upright post, adjacent upright posts are connected through a spring. Compared with the prior art, the road safety guardrail is featured by collision prevention, warning and reminding, convenient installation, high reliability and others; thus the road safety guardrail improves the safety of road driving, reduces the road accident, decreases the personal injury of passengers, and solves the shortcomings of big collision rigidity, unstable structure, and low safety coefficient of the traditional road guardrail; the road safety guardrail is especially suitable for sudden turn protection, high-speed protection and ordinary road protection, and so on.

Description

technical field [0001] The invention relates to a road safety guardrail, which belongs to the technical field of road guardrails. Background technique [0002] With the development of the economy, the road traffic is more and more developed, and the traffic network is getting bigger and bigger. my country has the most developed expressway network in the world. Urban and rural roads are also repaired to the last kilometer, which greatly facilitates people's production and life. [0003] However, traffic accidents in recent years also appear to be high-incidence, and the annual traffic accidents remain high. As a result, there are endless examples of family ruin and loss of life and wealth. On the one hand, it is due to the low quality of drivers and passengers and weak safety awareness; on the other hand, it is because our road safety measures are not in place. Injuries to innocent people and car crashes caused fatalities. We feel deeply helpless and sigh for this. [0...
