anti-collision shelf

Abstract

An anti-collision height-limiting frame of the present invention comprises a cross bar and two uprights supported at both ends of the cross bar, and the bottom end of the uprights is connected to the foundation through a flange; the cross bar includes a first inner tube and a first outer tube. A first anti-collision body is arranged between an inner pipe and the first outer pipe, and concrete is filled in the first inner pipe; the column includes a second inner pipe and a second outer pipe, and a The second anti-collision body, the second inner tube is provided with a reinforcing core and filled with concrete; the first anti-collision body and the second anti-collision body are both magnetorheological elastomers and the outside is wound with an electromagnetic coil, and the crossbar is provided with The infrared sensor is equipped with a control module and a power module on the flange. The height of the vehicle is detected by the infrared sensor and transmitted to the control module. The elastic body applies a magnetic field to adjust its damping and stiffness, so that the height-limiting rod has better vibration reduction and anti-collision effects, and prevents serious damage caused by super-high vehicle collisions.

Description

technical field [0001] The invention belongs to the technical field of road facilities, and relates to an anti-collision limit elevated shelf. Background technique [0002] In recent years, my country's road transport has developed rapidly, and motor vehicles have increased rapidly, especially large dump trucks, container vehicles and special-purpose vehicles. Vehicles often need to pass through railway bridges, highway bridges, tunnels and other buildings during driving. Accidents of super-high vehicles colliding with railways and highways occur from time to time. These collision accidents pose a huge threat to the safe transportation of our country. In order to ensure safety and prevent super-high vehicles from colliding with the above-mentioned buildings and causing damage, it is a common way to set up height-limiting overhead. Most of the height-limiting frames are made of welded section steel, and the beams are fixedly connected to the vertical poles. However, this typ...

AI Technical Summary

Problems solved by technology

Most of the height-limiting frames are welded with section steel, and the beams are fixedly connected to the vertical poles. However, this type of height-limiting frame absorbs less stress when the vehicle collides, which will cause a great impact on the vehicle and cause vehicle damage.
