Description

Rotatory pier buffer stop in advance

Technical Field

The invention relates to a pier anti-collision device, in particular to a pre-rotating pier anti-collision device, and belongs to the technical field of traffic safety.

Background

The bridge pier protection of the cross-sea and cross-river bridge in the prior art is not thorough enough, and the bridge pier is easy to collapse when a ship impacts the bridge pier, so that the bridge is greatly damaged, and the normal use of the bridge is influenced.

The utility model discloses an application number is 201721367294.7's utility model patent discloses a pier with rotatory collision avoidance device, it absorbs the energy that the striking produced through damping spring, buffer layer and shock absorber, forces the hull redirecting through the pivot of rolling, improves the security performance of pier and hull. However, the protection device on each pier in the patent needs a plurality of shock absorbers, which causes the shock absorption cost to be too high, and a large gap exists between every two adjacent rolling rotating shafts, because the ship directly impacts on the outer surface of the device, when the ship impacting device causes large deformation, some materials deformed due to impact may fill the gaps, so that the rolling rotating shafts cannot rotate continuously, and the device enters a blocking state, cannot rotate and loses the original functions of the device.

The invention patent No. 201310745312.0 discloses a collision avoidance device for a bridge pier, which guides the impact force of an object such as a ship to deviate from the bridge pier by the rotation of a spherical rolling element, thereby transferring the impact force to a certain extent. But the problem that its exists is similar with the problem that roll pivot exists in the above-mentioned utility model patent, when the impact is great promptly, easily makes the device get into a card dead state, and unable rotation loses the original function of device. In addition, the stress time is prolonged through the outer anti-collision assembly in the patent, and the impact force is deviated relative to the bridge pier through the cooperation with the rolling rotating shaft. However, in the device, the outer anti-collision frames are densely arranged outside the anti-collision layer, and the ship directly collides with the outer anti-collision frames to form layer-by-layer rotation of the whole device. Namely, the ship starts to rotate after the collision and does not rotate before the ship collides with the pier, so that the speed of the ship during the collision is too high, and the collision force of the ship against the pier is large.

In addition, most of the prior art only aims at piers with one cross section shape, and the prior art cannot be generally applied.
