Cylindrical fender

Abstract

The invention discloses a cylindrical fender. The cylindrical fender comprises a fender body and suspension devices connected to two sides of the fender body, wherein the fender body is provided with a main body part of which the section is ring-shaped, and a hollow cavity body is formed in the axial direction of the main body part; and each suspension device comprises a base, a clamping ring fixed to the base, a steel roll arranged on the hollow cavity in a penetrating manner, and a chain connected to the clamping ring and the steel roll. The cylindrical fender disclosed by the invention has the advantages that the cylindrical fender is low in reaction force, low in surface pressure, and reasonable in energy absorption quantity; the cylindrical fender is simple in shapes and convenient to mount, repair and maintain; the cylindrical fender is free from the influence of sizes of ships and sizes of docks, and wide in purposes; the cylindrical fender is high in adaptability to rolling and pitching of ship berthing; and the cylindrical fender can be used as a suspension type defence device for various ships and various docks.

Description

technical field [0001] The application relates to a protective device for ships and docks, in particular to a cylindrical fender. Background technique [0002] Rubber fender is an inflatable or water-filled rubber cushioning product used on docks or ships. It is mainly used to slow down the impact between the ship and the wharf or the ship when docking or mooring, and protect the ship and the wharf from damage. Generally, it is composed of pure rubber or rubber and metal skeleton and ply. It is molded and vulcanized by lamination molding method, or molded first and then vulcanized with a vulcanization tank. Rubber fenders are widely used in ports, docks and ships. [0003] The currently used fenders are mainly installed on the hull and docks with discarded tires. Although they can play a role in isolation, due to the lack of elasticity of discarded tires, they will still damage the hull and docks in the event of a collision. For discarded tires, people are also working o...

AI Technical Summary

Problems solved by technology

[0003] The fenders currently used are mainly installed on the hull and docks with discarded tires. Although they can play a role in isolation, due to the lack of elasticity of discarded tires, they will still damage the hull and docks in the event of a collision.

For discarded tires, people are also working on researching fenders of other structures, but their structures are unreasonable, poor elasticity and insufficient rebound force during collisions, so the anti-collision ability and cushioning performance are poor; Can cause fenders to tear, resulting in short service life
