Guided highway guard device

Abstract

The invention provides a guided highway guard device which comprises at least two L-shaped guard rails and a plurality of buffer cylinders. The plurality of L-shaped guard rails are sequentially stacked from front to rear, each L-shaped guard rail includes a horizontal plate, a vertical frame and a screw, the horizontal plate is vertically connected with the front of the vertical frame, the rear end of the horizontal plate of the L-shaped guard rail relatively at the front is stacked at the front end of the horizontal plate of the L-shaped guard rail relatively at the rear, and the horizontalplates of every two adjacent L-shaped guard rails are stacked through screws. The guided highway guard device can overcome resistance movement and absorb impact energy through the L-shaped guard railsand can also guide and buffer impact energy through the buffer cylinders, the buffering effect is good, and intense collision accidents are reduced.

Description

Technical field [0001] The invention belongs to the field of road safety, and particularly relates to a guided highway protection device. Background technique [0002] The traditional anti-collision guardrail is composed of a column and a protective plate located on the upper part of it. The protective plate can be made of steel plate or concrete, and the two are rigid materials and rigidly connected. When the car runs out of control and hits the protective plate, because the above structure has no buffer function, and the protective plate is a single-layer structure, under the high impact of the car, the protective plate will often be broken, and the car will still rush forward after breaking through the guardrail. The collision between the car and the anti-collision barrier is rigid, and the car will be seriously damaged after the collision. In order to strengthen the anti-collision ability of the anti-collision barrier, there are thickened protective panels in the market. Alt...

AI Technical Summary

Problems solved by technology

When the car runs out of control and hits the protective plate, because the above-mentioned structure has no buffer function, and the protective plate is a single-layer structure, under the high impact force of the car, the protective plate will often be broken, and the car will still rush forward after breaking through the guardrail, and The car and the crash barrier are rigidly collided, and the car will be seriously damaged after the collision

In order to enhance the anti-collision ability of the anti-collision guardrail, there are thickened protective plates in the market. Although the anti-collision performance of the protective plate has been improved, the weight of the steel plate or concrete is relatively large, so the thicker protective plate is bound to increase greatly. Heavy, causing inconvenience to handling, thus affecting the use
