Modular multilevel buffer anti-collision guardrail

Abstract

The invention discloses a modular multilevel buffer anti-collision guardrail. The modular multilevel buffer anti-collision guardrail comprises sliding grooves, long round steel pipes and short round steel pipes, bearings are arranged at the two ends of the long round steel pipes and the two ends of the short round steel pipes, the first bearings on the outmost sides of the two ends of the long round steel pipes are all located in the sliding grooves, and can slide along the sliding grooves, the lower ends of the long round steel pipes are provided with rolling wheels, the rolling wheels can roll in the lower sliding groove located at the bottom, screw holes are reserved in the short round steel pipes, anti-collision plates are arranged between the bearings on the innermost sides of the two ends of the short round steel pipes, every two adjacent long round steel pipes are connected through two stretchable devices, the adjacent long round steel pipes and short round steel pipes are connected through connecting rods, each short round steel pipe and the two corresponding adjacent long round steel pipes form a V-shaped structure, and then the whole anti-collision system is formed. The modular multilevel buffer anti-collision guardrail is simple in structure, reasonable in structure, high in modularization degree, convenient to transport, convenient to install, simple to maintain, good in anti-collision effect, wide in application range and relatively good in economic effect.

Description

technical field [0001] The invention relates to an anti-collision barrier, in particular to a modular multi-stage buffer anti-collision barrier. Background technique [0002] With the rapid development of my country's road construction and transportation industry, traffic safety is facing a severe situation. As a safety facility, crash barriers play an important role in protecting the traffic safety of roads and bridges. Generally, crash barriers mainly include three types: rigid barriers, semi-rigid barriers and flexible barriers. Rigid guardrails have strong protection ability, and the impact damage to accident vehicles and occupants is great. As a special traffic path, the tunnel is different from other road traffic. Because of the limitation of road speed, space and light, the probability of traffic accidents is greatly increased, and most of the existing anti-collision barriers have insufficient protection. Therefore, Invent a kind of non-rigidity, the anti-collision...

As a special traffic path, the tunnel is different from other road traffic. Because of the limitation of road speed, space and light, the probability of traffic accidents is greatly increased, and most of the existing anti-collision barriers have insufficient protection. Therefore, Inventing a non-rigid, anti-collision barrier with good anti-collision effect has become an urgent problem to be solved
