Anti-collision beam and anti-collision device with anti-collision beam

Abstract

The invention discloses an anti-collision beam and an anti-collision device with the anti-collision beam, and relates to the field of bridge protection. The anti-collision beam comprises a shell which is of a hollow structure and in a V shape, a plurality of separated cabins are arranged inside the shell, and the separated cabins are filled with elastic energy dissipation structures. Each elastic energy dissipation structure comprises a lattice box which is of a sealed structure and filled with elastic materials. When the anti-collision beam is impacted by a ship, the ship can slide along the surface of the anti-collision beam through the V-shaped structure arrangement, and kinetic energy exchange between the ship and a pier is reduced; each separated cabin is filled with the elastic energy dissipation structure which is good in elasticoplastic deformation capacity, and therefore part of impact energy can be absorbed and dissipated while impact time is effectively prolonged. The anti-collision beam is stable in structure, not prone to damage, reliable in anti-collision function, long in service life and suitable for the ocean environment with large wave acting force.

Description

technical field [0001] The invention relates to the field of bridge protection, in particular to an anti-collision beam and an anti-collision device with the anti-collision beam. Background technique [0002] Due to the large tonnage of the existing maritime navigation ships, when the ship passes the sea-crossing bridge, it is easy to collide with the caps or piers of the bridge. In severe cases, the caps or piers will be broken and damaged. Anti-collision steel casings are set on the periphery. After the ship hits the anti-collision steel box, the collision will consume the kinetic energy of the ship, making the ship decelerate, thereby reducing the impact force of the ship. [0003] When the mass of the ship is large and the speed of the ship is fast, the impact force is large, which may easily cause the anti-collision steel casing to break or even crack, and continue to collide with the pier or cap under the action of inertia, resulting in damage to the bridge. At the sa...

Problems solved by technology

[0003] When the mass of the ship is large and the speed of the ship is fast, the impact force is large, which may easily cause the anti-collision steel casing to break or even crack, and continue to collide with the pier or cap under the action of inertia, resulting in damage to the bridge. At the same time, the ship body It will also be greatly damaged; furthermore, the damaged anti-collision steel box is easily corroded under the action of air and water flow, and the anti-collision performance drops sharply

[0004] The invention patent with application number 200910213083.1 discloses a self-floating composite material bridge water pressure anti-collision device. The patent includes a shell part, which is composed of a composite material surface layer, a sandwich material layer and a filling material body. The interior of the moso bamboo is filled with moso bamboo, and the gap between moso bamboo is filled with a mixture of wood chips and resin, or rubber particles. Due to the limited rigidity of fiber reinforced composite materials, it is easy to be damaged if it is located in waters with relatively turbulent water flow for a long time.

[0005] The invention patent with the application number 20010213082.7 discloses a bridge cap composite material anti-collision column. Due to the limitation of the shell material, the size of the anti-collision column is small, and the anti-collision column is easily damaged
