A universal joint type anti-collision device

Abstract

The invention provides a universal joint type anti-collision device. The universal joint type anti-collision device is formed by assembling a plurality of unit bodies around a protected unit. Each unit body is composed of an anti-collision unit and an anti-collision platform. The anti-collision unit and the anti-collision platform are connected through universal joints. Each anti-collision unit comprises a porous energy absorption structure A and a hollow structure. Semispherical rubber balls are arranged on the inner side, the left side and the right side of each anti-collision unit. The positions of the semispherical rubber balls correspond to the positions of semispherical rubber balls on the anti-collision platforms. Each anti-collision platform comprises a porous energy absorption structure B, a platform base and a two-wing buffer structure. Rails for the universal joints are arranged on the upper portion of the platform bases and intersect and communicate with one another. Friction block bodies can move on the rails. The tops of the universal joints are connected with the bottoms of the anti-collision units. The bottoms of the universal joints are connected with the friction block bodies through rivets. The anti-collision device is reasonable in structure, has buffer and energy absorption effect and can effectively reduce collision force of ships, and meanwhile the universal joint type anti-collision device has the beneficial effects of being rapid to construct, convenient to maintain and good in corrosion resistance.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to a universal joint type anti-collision device, which belongs to the field of safety protection of building structures on oceans and rivers. Background technique [0002] In recent years, with the rapid development of the shipping industry, the number of ships on the sea and rivers has increased year by year, the channel has become increasingly congested, the tonnage and carrying weight of ships have increased rapidly, and the speed of navigation has also increased significantly, and accidents on ships, bridges, and offshore platforms have become increasingly frequent In addition, in cold regions, it is not uncommon for ice floes to hit offshore platforms or offshore structures. In the event of a collision accident, the loss is often huge, which may cause the collapse of offshore buildings or bridges or damage to the main structure, casualties, and sinking of ships. pollution and huge e...

Problems solved by technology

When this type of floating protection structure is impacted, it often absorbs or dissipates the impact kinetic energy of the ship through the destructive deformation of the structure to achieve anti-collision protection for the pier. The attenuation effect of the impact force of the ship is small, which easily leads to damage or destruction of the pier and the ship

In addition, the rigid contact connection between the floating steel box and the protective structure (such as the bridge pier) cannot weaken the transmission of the ship's force, and the momentum buffer performance is poor

In addition, the material used for the main body of the anti-collision device is basically a single high-strength steel, which is easy to corrode in the marine environment, affecting the anti-collision performance, and even causing the anti-collision device to fail

Therefore, the structural structure and materials of the anti-collision facilities need to carry out technological innovation, and those skilled in the art are also constantly trying new solutions, but these problems have not been well resolved
