Problems solved by technology

[0002] The anti-resistance block is the load-bearing part between the wave beam and the column. It is an energy-absorbing component. After the guardrail is hit by a collision, the anti-resistance block can be gradually deformed to effectively absorb the collision energy and reduce the collision force, reducing the casualties of passengers. However, the existing anti-blocking blocks have limited space for reducing the collision force, and cannot effectively slow down the collision force.

Abstract

The invention discloses a highway guardrail magnetic barrier, comprising a cross-shaped pillar, barrier blocks, elastic supports, dual-wave beams, first screw units, and second screw units; the two barrier blocks are arranged symmetrically on two sides of the cross-shaped pillar and are of hexagonal hollow tubular structure; the barrier block close to one side of the cross-shaped pillar is provided with a rectangular groove; two elastic supports are arranged in the center of each barrier block; the barrier blocks and the elastic supports are connected with the cross-shaped pillar through the first screw units and are connected with the dual-wave beams through the second screw units. The highway guardrail magnetic barrier has good connection reliability and good stress-bearing performance,as well as collision prevention, is simple to mount and convenient to maintain, and can effectively ensure safety of a driver.

Description

technical field [0001] The invention belongs to the technical field of road protection facilities, in particular to a magnetic anti-drag block for a road guardrail. Background technique [0002] The anti-resistance block is the load-bearing part between the wave beam and the column. It is an energy-absorbing member. After the guardrail is hit by a collision, the anti-resistance block can be gradually deformed to effectively absorb the collision energy and reduce the collision force, reducing the casualties of passengers. However, the existing anti-blocking block has limited space for reducing the collision force, and cannot effectively slow down the collision force. Contents of the invention [0003] The purpose of the present invention is to provide a magnetic anti-blocking block for road guardrails, which is reliable in connection, good in force performance, good in anti-collision performance, easy to install, easy to maintain and repair, and can effectively guarantee th...
