Damper and damper-based bridge anti-collision device

Abstract

The invention discloses a damper and a damper-based bridge anti-collision device. The damper comprises a tapered sleeve (1) and a horizontal top rod (2), wherein the tapered sleeve (1) is large in front part and small in rear part; multiple layers of partition plates (3) vertical to the axis of the tapered sleeve (1) are arranged in the tapered sleeve (1); a center hole runs through each layer of partition plate (3); the top rod (2) passes through the center holes of all partition plates (3); multiple layers of top plates (4) which correspond to the partition plate (3) one by one are fixed on the top rod (2); the distance between each layer of top plate (4) and the partition plate (3) corresponding to the top plate (4) is gradually increased from front to back; the bridge anti-collision device comprises a pier anti-collision assembly and a bridge plate anti-collision assembly; the pier anti-collision assembly comprises four dampers and an arc-shaped plate; and the bridge plate anti-collision assembly comprises four dampers and a flat plate. The damper and the damper-based bridge anti-collision device are simple in structure, convenient to manufacture and ideal in damping effect.

Description

technical field [0001] The invention relates to the field of bridge safety, in particular to a shock absorber and a bridge anti-collision device based on the shock absorber. Background technique [0002] When the hull passes through the bridge hole of the bridge, the pier and the lower part of the bridge plate of the bridge are easily hit by the hull, and the conventional anti-collision measure is to coat the side of the bridge pier and the bridge plate with a layer of anti-collision film. It has a certain protective effect, but it is still a rigid touch in essence, and its shock absorption and anti-collision effect is not good, and the bridge pier, the side of the bridge deck, and even the hull itself are inevitably damaged due to collision. SUMMARY OF THE INVENTION [0003] A technical problem to be solved by the present invention is to provide a shock absorber with simple structure, convenient manufacture and ideal shock absorption effect. [0004] A technical solution...

Problems solved by technology

[0002] When the hull passes through the bridge opening of the bridge, the pier and lower part of the bridge deck of the bridge are easily hit by the hull, and the conventional anti-collision measure is to coat the pier and the side of the bridge deck with a layer of anti-collision film, but the above-mentioned anti-collision measures can play a role. It has a certain protective effect, but it is still a rigid contact in essence. Its shock absorption and anti-collision effects are not good. The pier, the side of the bridge plate and even the hull itself will inevitably be damaged due to collision.
