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.
