Highway crash barrier

Abstract

The invention provides a highway crash barrier which comprises a bottom plate, V-shaped frames are installed on the two sides of the surface of the top end of the bottom plate, a cross beam is connected between the top ends of the V-shaped frames, a transverse support is arranged at the bottom of the cross beam, sleeves are connected with the two ends of a rotating rod in a sleeving mode, buffer bodies are movably connected with the surfaces of the outer ends of reinforcing vertical rods in a sleeving mode, extension rods are connected with the interiors of the sleeves in a sleeving mode, abutting rods are connected between the extension rods, a plurality of first locking knobs are arranged on the surfaces of the outer ends of the sleeves, a limiting buckle is arranged in the middle of the surface of the top end of the bottom plate, two supporting rods penetrate through the two sides of the bottom plate, and the bottom ends of the supporting rods are connected with friction plates. According to the highway crash barrier, after the sleeves are rotated outwards, the abutting rods abuts against the ground, the overall side face of the crash barrier is of a triangular structure, when a vehicle collides with the crash barrier, the crash barrier can be prevented from being directly overturned, the vehicle has longer braking time, meanwhile, the buffer bodies absorb force generated when the crash barrier collides with the vehicle head, and damage to the vehicle body is reduced.

Description

technical field [0001] The invention relates to the field of traffic protection, in particular to a highway anti-collision barrier. Background technique [0002] The anti-collision guardrail is an industrial "guardrail", which is mainly used for the protection and protection of equipment and facilities in factories, workshops and warehouses. It is usually made of steel, such as round steel pipe, square steel pipe or profiled steel plate. Highway anti-collision guardrail is the most important traffic infrastructure. my country's expressway was developed in the 1980s. It plays an important role in the development of national economy and society. It is an important maintenance and safety guarantee facility for highways. [0003] When the vehicle is driving on the road, especially at high-speed exits, urban school entrances, unit gates, etc., it is often necessary to set up anti-collision barriers to restrict vehicles. However, the current anti-collision barriers have poor buff...

Problems solved by technology

[0003] When the vehicle is driving on the road, especially at high-speed exits, urban school entrances, unit gates, etc., it is often necessary to set up anti-collision barriers to restrict vehicles. However, the current anti-collision barriers have poor buffer performance and cannot be effective. The anti-collision effect is very good, and the anti-collision barrier is easy to fall over when it is hit by a collision. The vehicle is pressed on the anti-collision barrier and still slides forward and cannot brake effectively, which will easily cause the vehicle to "fly" to the side of the road, causing greater harm to the people on the vehicle. harm
