Collision-prevention device for preventing ultrahigh vehicle from colliding bridge

Abstract

The invention discloses a collision-prevention device for preventing an ultrahigh vehicle from colliding a bridge. The collision-prevention device comprises a shock resistant panel, an energy dissipation tube device comprising a plurality of energy dissipation tubes, connecting chains, a two-wing erected frame and a backboard; the front end of the energy dissipation tube device is provided with the shock resistant panel; two sides of the energy dissipation tube device are provided with inverted T-shaped erected stages; the back end of the energy dissipation tube device is provided with the L-shaped backboard; the L-shaped backboard is arranged on a bridge structure; the inverted T-shaped erected stages are connected with the L-shaped backboard; the connecting chains are connected on the upper and lower sides of the energy dissipation tube device. The energy dissipation tube device can effectively absorb energy generated by collision between the ultrahigh vehicle and the bridge, so that the damage brought by the collision of the ultrahigh vehicle to the bridge structure is greatly reduced or eliminated. The collision-prevention device for preventing the ultrahigh vehicle from colliding the bridge is simple in structure and convenient to mount; after the energy dissipation tube device is damaged, the damaged energy dissipation tube device can be easily replaced, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of road and bridge safety equipment, and in particular relates to an anti-collision device for preventing ultra-high vehicles from colliding with bridges. Background technique [0002] With the advancement of my country's urbanization process and the increasing prosperity of the national economy, the transportation industry has developed rapidly, especially the construction of a large number of three-dimensional transportation, which has largely eased the pressure on urban ground transportation. Traffic facilities such as woven overpasses, viaducts, and pedestrian bridges can be seen everywhere, and at the same time, bulky freight vehicles and engineering vehicles are also increasing rapidly. The traffic accidents that follow have also increased significantly, thereby seriously affecting traffic safety and road traffic. Among them, the cases of ultra-high vehicles colliding with the bottom structure of the ...

AI Technical Summary

Problems solved by technology

However, due to the small structural area at the bottom of the upper bridge and the relatively high requirements on weight and structure, there are very few such anti-collision devices at home and abroad.
