Description

Highway guardrail magnetic block

technical field

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

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.

Further, the two magnets are strong NdFeB magnets with the same polarity.

Further, a bolt hole is provided at the center of the cross-section of the support column and the magnet adsorbed thereto, and is fastened with a bolt rod.

Further, the cross-shaped column, the anti-blocking block, the mounting plate, and the double wave beam are all provided with bolt holes.

The advantages and beneficial effects that the present invention has are:

The magnetic anti-blocking block of the road guardrail of the present invention has cross-shaped uprights, anti-blocking blocks, elastic supports, double wave beams, the first screw assembly, and the second screw assembly, and the anti-blocking blocks are two pieces, symmetrically arranged at ten On both sides of the glyph column, the anti-blocking block is a hexagonal hollow cylindrical structure. The anti-blocking block on the side of the cross-shaped column is provided with a rectangular groove matching the cross-shaped column. Two elastic supports are set in the middle of the anti-blocking block. The anti-blocking block and the elastic support are connected to the cross-shaped column through the first bolt assembly, and the anti-blocking block and the elastic support are connected to the double wave beam through the second bolt assembly. Such a structure has reliable connection, good force bearing performance, good anti-collision performance, simple installation, convenient maintenance and repair, and can effectively guarantee the safety of the driver.
