ship fender

Abstract

The invention discloses a ship fender device. The ship fender device comprises at least two parallel slide ways located on a quayside. Baffles are arranged at the two ends of the parallel slide ways, a pair of rollers are arranged in the parallel slide ways, the two rollers are connected through a spring buffer, each roller is hinged to one end of a supporting rod through a connecting shaft, the other ends of the supporting rods are hinged to a cylindrical ring at the same time, the cylindrical ring is fixed to a bottom plate, the bottom plate is fixedly installed on a steel frame structure, and a rubber fender is installed on the steel frame structure. According to the ship fender device, when a ship is drawn alongside, firstly, the ship makes contact with the rubber fender, the rubber fender and the ship interact, internal air is compressed to work to consume collision energy, the ship is primarily buffered, then the spring buffer is used for secondary buffering, compression springs carry out tertiary energy dissipation, when the ship collision energy is too large, air bags are inflated, and due to at least three times of energy dissipation, the energy dissipation effect is good.

Description

technical field [0001] The invention relates to a ship fender and belongs to the field of ships. Background technique [0002] A fender is a kind of elastic buffer device used on the edge of a dock or ship, which is made of wood or rubber. It is mainly used to slow down the impact force between the ship and the wharf or the ship during the berthing or mooring process, and prevent or eliminate damage to the ship and the wharf. With the gradual development of technology, the current rubber fenders are generally divided into solid type (non-floating type) and floating type. Practice has shown that the impact force of a ship during berthing or mooring is very large, and traditional rubber fenders (solid rubber fenders and floating rubber fenders) basically only have a buffering effect on collisions, and the buffering effect is not good. Obvious, and costly. Although the common floating rubber fenders are low in cost and easy to install, they generally only have a simple buffe...

Practice has shown that the impact force of a ship during berthing or mooring is very large, and traditional rubber fenders (solid rubber fenders and floating rubber fenders) basically only have a buffering effect on collisions, and the buffering effect is not good. Obvious and costly

Although the common floating rubber fenders are low in cost and easy to install, they generally only have a simple buffering effect on collisions, which is not enough for some large ships.
