A road crash barrier

Abstract

The invention discloses a road anti-collision barrier, comprising a bottom plate, a V-shaped frame is installed on both sides of the top surface of the bottom plate, a cross beam is connected between the top ends of the V-shaped frame, the bottom of the cross beam is provided with a transverse support, Both ends are sleeved with sleeves, the outer end surface of the reinforcing vertical rod is movably sleeved with a buffer body, an extension rod is sleeved inside the sleeve, and abutting rods are connected between the extension rods, and the outer end surface of the sleeve is provided with There are a plurality of first locking knobs, a limit buckle is arranged in the middle of the top surface of the bottom plate, two support rods are pierced through both sides of the bottom plate, and the bottom end of the support rod is connected with a friction plate. In the present invention, by rotating the sleeve to the outside, the abutting rod is abutted against the ground, so that the whole side of the anti-collision barrier is in a triangular structure, and when the vehicle collides, the collision barrier can be prevented from directly overturning, so that the vehicle has a longer braking time. At the same time, the buffer body absorbs the force generated when it collides with the front of the car, reducing the damage to the body.

Description

technical field [0001] The invention relates to the field of traffic protection, in particular to a road 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. Commonly used steel, such as round steel pipe, square steel pipe or profiled steel plate. The highway anti-collision barrier is the most important transportation infrastructure. my country's expressway has been developed since the 1980s. It plays an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility for highways. [0003] When the vehicle is driving on the highway, especially in the expressway entrance, urban school entrance, unit gate and other places, it is often necessary to set up anti-collision barriers to limit the traffic of vehicles. However, the curre...

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
