Steel fender

Abstract

The invention discloses a steel fender. The steel fender comprises a first steel fender body arranged on a wharf and a second steel fender body arranged on a ship hull plate, the first steel fender body corresponds to the second steel fender body in position, the first steel fender body and the second steel fender body can be in butt joint selectively, the thickness of the first steel fender body is L1, the thickness of the second steel fender body is L2, the working thickness of a rubber fender arranged on the wharf is L3, and the thickness L1 of the first steel fender body, the thickness L2 of the second steel fender body and the working thickness L3 of the rubber fender have the relationships that L1+L2>L3, and L1<L3; the first steel fender body and the second steel fender body are correspondingly arranged on the wharf and the ship hull plate, the buffer action on a semi-submersible barge can be achieved during semi-submersible barge mooring, and collision between the semi-submersible barge and the wharf is prevented; the thickness of the first steel fender body arranged on the wharf is smaller than the working thickness of the rubber fender, and therefore other ships can be moored through the rubber fender, and collision between the ships and the first steel fender body can be avoided.

Description

technical field [0001] The invention relates to the technical field of protection devices for berthing ships, in particular to a steel fender. Background technique [0002] After the ship built on the flat land is completed, the ship needs to be lifted to the semi-submersible barge by the ship moving trolley. Before lifting, the semi-submersible barge needs to be tied to the wharf and docked with the track on the ground. There is usually a buffer between the semi-submersible barge and the wharf to prevent the semi-submersible barge from directly contacting the wharf. When the buffer between the semi-submersible barge and the wharf is a skid or rubber pad, because the semi-submersible barge has a relatively large pressing force on the pier when the ship is lifted, the skid or rubber pad is easily compressed, causing The relative distance between the semi-submersible barge and the ground changes greatly, or the track of the semi-submersible barge and the ground is not on the ...

AI Technical Summary

Problems solved by technology

When the buffer between the semi-submersible barge and the wharf is a skid or rubber pad, because the semi-submersible barge has a relatively large pressing force on the pier when the ship is lifted, the skid or rubber pad is easily compressed, causing The relative distance between the semi-submersible barge and the ground changes greatly, or the track of the semi-submersible barge and the ground is not on the same straight line, resulting in certain risks in lifting the ship to transfer the barge; The steel fenders are usually thicker than the rubber fenders of the wharf, so that the steel fenders need to be removed when the wharf berths other ships, so that the ships can lean on the rubber fenders, which makes the setting of the steel fenders more inconvenient
