Safety guardrail for highway construction

Abstract

The present invention relates to a safety guardrail for highway construction. The safety guardrail comprises a rectangular frame and a steel wire net arranged on the front side of the frame, a plurality of buffering assemblies are horizontally and evenly distributed on the frame, and each buffering assembly is formed by universally hinging two rollers which are coaxially arranged up and down; a plurality of guide rods in one-to-one correspondence with the buffering assemblies are arranged on the frame, the upper ends of the guide rods are vertically connected with the frame in a sliding mode and connected with the frame through first springs, the guide rods slide upwards under the elastic force of the first springs, and the lower ends of the guide rods are universally hinged to the upper ends of the buffering assemblies; a plurality of positioning rods in one-to-one correspondence with the buffering assemblies are arranged on the frame, the lower ends of the positioning rods are rotationally connected with the frame, and the upper ends of the positioning rods are universally hinged to the lower ends of the buffering assemblies. Impact force in all directions can be effectively decomposed, buffered and resisted in a multiple mode, the protection effectiveness is greatly improved, the overall service life of the guardrail is prolonged, the guardrail can be recycled, and unnecessary material and labor cost is reduced.

Description

technical field [0001] The invention relates to an auxiliary device for road construction, in particular to a safety guardrail for road construction. Background technique [0002] The road construction process requires a large number of on-site construction personnel. At the same time, the traffic in the construction section of the highway construction is usually relatively congested, and traffic accidents are prone to occur. Deep pits and large-scale construction equipment will also pose a considerable safety threat to intruding vehicles; therefore, in the process of road construction, the construction site is usually surrounded by protective fences, and the existing protective fences are all temporary steel bars and iron sheets. It is time-consuming and labor-intensive to build, and the protection effect is insufficient. It has a significant effect on the isolation of pedestrians. However, when encountering a vehicle or other large-scale mechanical impact, it cannot effect...
