High-strength anti-collision buffer fender device

Abstract

The invention discloses a high-strength anti-collision buffer fender device. The high-strength anti-collision buffer fender device comprises a rubber plate A and a rubber plate B which are parallel to each other. A plurality of sets of elastic units of the same structure are arranged between the rubber plate A and the rubber plate B. Each set of elastic unit comprises a first rigid connecting plate, a second rigid connecting plate and a spiral spring, wherein the first rigid connecting plate is fixedly connected to the side face of one side of the rubber plate A; the second rigid connecting plate is fixedly connected to the side face of the side, adjacent to the rubber plate A, of the rubber plate B; the first rigid connecting plate and the second rigid connecting plate are symmetrically arranged; and the spiral spring is connected between the first rigid connecting plate and the second rigid connecting plate. The side face of the side, used for being connected with the elastic units, of the rubber plate A, and the side face of the side, used for being connected with the elastic units, of the rubber plate B are each provided with a plurality of rubber plate protrusions extending in the height direction of the spiral springs. The high-strength anti-collision buffer fender device is of a two-stage rigidity structure, has the good buffer effect instantly when being stressed and facilitates modularized mounting and manufacturing.

Description

technical field [0001] The invention relates to a device for alleviating collision when a ship is docking with a ship, in particular to a high-strength anti-collision buffer fender device, which belongs to the technical field of ship equipment vibration reduction. Background technique [0002] When a ship is operating alongside a ship, or when a ship enters a port, river, repair dock, etc., collisions and vibrations will inevitably occur. And this kind of vibration will damage the hull structure and mechanical equipment on board, and affect the working environment of the crew. Especially for large engineering ships, the mass, weight, and momentum are large, and the vibration is particularly obvious when a collision occurs. Need a kind of high-strength energy-absorbing big, good anti-collision cushioning device of cushioning performance. Therefore, the anti-collision work of ships is of great significance. [0003] At present, the fender devices on ships mainly include rub...

AI Technical Summary

Problems solved by technology

This device has uniform force and excellent wear characteristics, but the amplitude is small and the elasticity is small. In the process of collision, the action time is short, and the dynamic load transmitted to the protected part is large, so the cushioning performance needs to be improved.
