Highway crash barrier capable of rotating smoothly

Abstract

The utility model discloses a highway crash barrier capable of rotating smoothly, and belongs to the technical field of highway barriers. The highway crash barrier capable of rotating smoothly comprises a base which is a vertical rod and a plurality of baffles, the baffles are connected through elastic structures, and the vertical rods are connected with the baffles through elastic structures. A groove is formed in the center of the base. Two supporting plates are sequentially connected to the left side and the right side of the outer surface of the vertical rod in a screwed mode from top to bottom, a plurality of supporting boxes are fixedly installed on the upper surface of the top supporting plate and the lower surface of the bottom supporting plate, a plurality of first through holes are formed in the inner wall of each supporting plate, and second through holes are formed in the upper end face and the lower end face of each baffle respectively. According to the invention, the elastic structures are arranged among the plurality of baffle plates; therefore, acting force among the baffles can be buffered conveniently under the action of the elastic structure, impact of vehicles running at a high speed or running slowly on the guardrail is weakened, and the highway crash barrier capable of rotating smoothly is more striking at night through the light reflection effect of the first light reflection belt and the second light reflection belt.

Description

technical field [0001] The invention relates to the technical field of highway guardrails, in particular to a smooth-rotatable highway anti-collision guardrail. Background technique [0002] The highway anti-collision guardrail that can rotate smoothly is the most important traffic infrastructure. The continuous structure spliced ​​with each other and supported by columns is made of high-quality low-carbon steel wire braided and welded with aluminum-magnesium alloy wire. It has the characteristics of flexible assembly and durability. It can be used as a permanent fence wall or as a temporary isolation net use. [0003] The smooth-rotating highway anti-collision guardrail mainly uses the deformation of the soil foundation as the column as the beam to absorb the collision energy, prevent the vehicle from rushing out of the road and cause the danger of vehicle damage and injury, so as to protect the vehicle and passengers and reduce the occurrence of traffic accidents. The ...

Problems solved by technology

[0005] In order to solve the impact damage to the occupants of the accident vehicle caused by the strong rigidity of the guardrail in the prior art and the collision between the driver and the smoothly rotatable highway anti-collision guardrail due to the harsh environment, the present invention provides a smoothly rotatable The highway anti-collision guardrail mainly installs an elastic structure between several baffles, so that the force between several baffles can be easily buffered under the action of the elastic structure, and the impact of high-speed or slow-moving vehicles on the guardrail can be weakened.
