Abstract

A pre-rotating pier anti-collision device belongs to the technical field of traffic safety. The invention solves the problem that the impact force on the bridge pier is too large when the existing bridge pier anti-collision device is hit by a ship. It includes an inner anti-collision assembly, a rotating assembly and an outer anti-collision assembly coaxially arranged in sequence from the inside to the outside. Outside the pier, the lower outer wall of the outer anti-collision assembly is provided with two pairs of grooves, and the two pairs of grooves are mirrored with respect to the central axis of the outer anti-collision assembly. A pilot assembly is also provided outside the pier, and the pilot assembly includes a bracket and two pairs of right-angled tamping rods, each of which has an L-shaped structure, and one end of each right-angled tamping rod is fixedly connected to a sphere, and the bracket is fixed on the pier at the lower part of the outer anti-collision assembly. The right-angle stamping rods are arranged oppositely in a rectangular shape and are slidably arranged on the lower part of the outer anti-collision assembly through the bracket.

Description

technical field [0001] The invention relates to a bridge pier anti-collision device, in particular to a pre-rotated bridge pier anti-collision device, which belongs to the technical field of traffic safety. Background technique [0002] The prior art is not thorough enough to protect the piers of bridges crossing seas and rivers. When a ship hits a pier, the pier is likely to collapse, thereby causing great damage to the bridge and affecting the normal use of the bridge. [0003] The utility model patent with the application number 201721367294.7 discloses a bridge pier with a rotating anti-collision protection device, which absorbs the energy generated by the impact through a shock-absorbing spring, a buffer layer and a shock absorber, and forces the hull to change direction by rolling the rotating shaft, improving the pier and the bridge. Safety performance of the hull. However, the protection device on each pier in this patent requires several shock absorbers, which make...
