Self-resetting bridge pier anti-collision structure

Abstract

A bridge pier body is fixedly connected with a fixing sleeve, the top and the bottom of the surface of the fixing sleeve are fixedly connected with a first annular sliding seat and a second annular sliding seat correspondingly, and the sides, close to each other, of the first annular sliding seat and the second annular sliding seat are rotationally connected with rotating sleeves; multiple sets of vertical plates are fixedly connected to the periphery of the rotating sleeve, a fixing base is rotationally connected to the vertical plates through movable shafts, a connecting plate is fixedly connected to the top of the side, away from the rotating sleeve, of the fixing base, an auxiliary bearing is fixedly connected to the side, away from the fixing base, of the connecting plate, and a fixing pipe is fixedly connected to the inner ring of the auxiliary bearing; the bottom end of the fixing pipe communicates with an anti-collision barrel, and protection mechanisms are arranged on the first annular sliding base and the rotating sleeve correspondingly. The problems that a traditional bridge pier anti-collision guardrail structure is poor in protection effect, impact force of ships cannot be guided to be unloaded, and a bridge pier is prone to being damaged are solved.

Description

technical field [0001] The invention belongs to the technical field of bridge piers and relates to a self-resetting bridge pier anti-collision structure. Background technique [0002] The bridge pier is a substructure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutment is located on both sides of the bridge, and the bridge pier is between the two abutments. Not only must it support the span structure of the bridge, but it must also connect with the embankment and prevent the embankment from slipping. In order to prevent the bridge pier from being damaged under the impact of ships, it is necessary to install an anti-collision barrier structure on the bridge pier. [0003] However, the protection effect of the traditional bridge pier anti-collision guardrail structure is poor. When the ship collides with the bridge pier, it cannot guide the ship, and the impact force of the ship cannot be directed outward, s...
