A double protection road spring buffer guardrail

Abstract

A double-protection highway spring buffer guardrail, which relates to the technical field of traffic facilities, has the following structure: a hole A is opened on the upper end of a column, a channel steel is used as a fixing frame, holes B are opened on both sides of the upper end, and the upper guardrail beam passes through the hole A, Hole B is connected with the column and hinged with the fixed frame. The two sides of the lower end of the fixed frame are respectively fixedly connected with the lower guardrail beam. One end of the screw is fixed on the fixed ear A on both sides of the lower end of the fixed frame. The spring is worn on the screw, and the other end of the screw is Pass through the long hole fixedly arranged on the fixed ear B at the lower end of the column and fix it with a nut. The beneficial effect of the present invention is: its structure is simple, and construction is convenient, guardrail pipe is provided with upper guardrail beam and lower guardrail beam, and the height of lower guardrail beam is 15-50cm, and when the vehicle loses control, the lower guardrail beam can block the wheel , The double spring buffer device can effectively play a buffer role, and at the same time can change the driving direction of the vehicle, and the upper guardrail beam plays a second buffer role, which can greatly reduce traffic accidents and personal injuries.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a double-protection highway spring buffer guardrail. Background technique [0002] With the development of the economy, the construction of a large number of urban roads, country roads and national highways, etc., and the substantial increase of vehicles, the incidence of traffic accidents is also on the rise. At present, there are no protective devices on both sides of most roads, and the existing guardrails are corrugated guardrail boards, cement guardrail walls or cement guardrail posts. In the event of a traffic accident, the vehicle may be driven directly out of the road without a guardrail, and if it is a mountain road, it is likely to fall into the bottom of the mountain, causing a serious accident. Existing highway guardrail, because the guardrail height is higher, when a traffic accident occurs, the guardrail will be damaged due to the huge impact force, and ...

AI Technical Summary

Problems solved by technology

In the event of a traffic accident, the vehicle may drive directly out of the road without a guardrail. If it is a mountain road, it is likely to fall into the bottom of the mountain and cause a serious accident.

Due to the high height of the existing highway guardrail, the guardrail will be damaged due to the huge impact force in the event of a traffic accident, and the vehicle will be knocked out of the road, which will cause serious damage to the vehicle and personal injury, resulting in serious traffic safety accidents
