Using method of automatic lifting safety road barrier for sidewalk at urban intersection

Abstract

The invention relates to the technical field of road intersection safety protection devices, in particular to an automatic lifting safety isolation pier for an urban intersection sidewalk and a using method thereof.The automatic lifting safety isolation pier comprises a safety island, two pre-buried box bodies are arranged below the safety island, and a set of self-adaptive expansion assemblies are arranged above the safety island; a set of automatic lifting assemblies are arranged in each pre-buried box body, a set of safe passing assemblies are arranged beside the safety island, and an automatic detection set is arranged on the side, close to the self-adaptive expansion assembly, of the upper portion of the safety island. The road barrier is simple in structure and convenient to use, traffic accidents caused by factors such as poor sight at night and large view blind areas of large trucks are avoided, under the action of the safe passing assembly, accidental injury to pedestrians during lifting of the road barrier can be effectively prevented, and effective protection can be provided for the pedestrians when natural disasters such as rainstorm or flood occur.

Description

technical field [0001] The invention relates to the technical field of road intersection safety protection devices, in particular to a method for using an automatic lifting safety isolation pier for sidewalks at urban intersections. Background technique [0002] With the rapid development of cities, China, as a country with a large population and a large traffic, has a traffic accident rate of 10,000 vehicles and a traffic accident death rate far surpassing developed countries such as Europe and the United States. This not only poses a threat to people's lives and property, but also violates the construction of safe transportation. The goal is that traffic light intersections, which are important control points in urban traffic, are high-incidence areas of traffic accidents. First, some pedestrians ignore traffic lights and have behaviors of running red lights. Vehicles collide with pedestrians due to lack of time to brake. Second, when large trucks turn right, there is a hu...

AI Technical Summary

Problems solved by technology

[0004] (1) The existing isolation pier has the phenomenon of accidentally injuring pedestrians and non-motor vehicles when it is raised and lowered, which still has hidden dangers to people's safety;

[0005] (2) The lifting speed of the existing isolation pier is relatively slow, and the time for pedestrians to pass at the intersection is very limited, especially during the peak traffic period, which greatly reduces the traffic efficiency;

[0006] (3) The existing isolation pier cannot provide effective protection for pedestrians in the event of natural disasters such as heavy rain or flood, and the practicability is poor
