Problems solved by technology

[0002] Most of the current guardrails are composed of wavy metal protective belts and anchoring devices. When an impact occurs, the protective belt produces longitudinal compression deformation to absorb energy, reducing the damage caused by the impact force, mainly relying on the material and shape of the protective belt itself to absorb energy; impact The contact area is small, the cushioning effect and protection degree are limited, and the vehicle damage is large
Especially when the vehicle has a side collision, due to the collision angle, the impact area is small and the damage to the vehicle body is more serious.

Abstract

The invention discloses a crash barrier, comprising a barrier beam and support portions. The barrier beam includes at least two linear main beams; the heads of the adjacent linear main beams are overlapped and fixed via bolts; the end of the linear main beam at the foremost end is fitly fitted with a crash portion that enables the linear main beam to bend and deform, and the side, facing a pavement, of the rest of the linear main beam is fitly fitted with a roller group; the support portions are arranged on the lateral side of the barrier beam, and the linear main beams are connected to a ground through the support portions. The crash barrier has the roller groups added to the surface of the barrier beam, so that when a vehicle experiences lateral crash, the crash direction can be changedunder the guidance of the rotary roller groups, so that the force is removed, and the vehicle is less damaged by the crash.

Description

technical field [0001] The invention relates to the technical field of road safety protection equipment, in particular to an anti-collision guardrail. Background technique [0002] Most of the current guardrails are composed of wavy metal protective belts and anchoring devices. When an impact occurs, the protective belt produces longitudinal compression deformation to absorb energy, reducing the damage caused by the impact force, mainly relying on the material and shape of the protective belt itself to absorb energy; impact The contact area is small, the cushioning effect and protection degree are limited, and the vehicle damage is large. Especially when a side collision occurs to the vehicle, due to the existence of the collision angle, the impact area is small and the damage to the vehicle body is more serious. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an anti-collision ...
