A rotatable multi-layer energy-absorbing dock fender

Abstract

The invention discloses a rotatable multi-layer energy absorption quay fender. The rotatable multi-layer energy absorption quay fender comprises a fender body, wherein the fender body is connected with an impingement plate; the impingement plate is connected with a pair of springs; the springs are fixedly connected with rotating arms respectively; the two rotating arms are respectively mounted at the two ends of a pivot; two upper connecting pillars are connected under the pivot; the upper connecting pillars are connected with lower connecting pillars through rubber springs; and the lower connecting pillars are connected with a quay through substrates. According to the rotatable multi-layer energy absorption quay fender, the purposes of multi-layer energy absorption and counterforce decrease are achieved under the situation that the quay fender does not occupy redundant space through the polyurethane fender body, the impingement plate, spring layers and the rubber springs between the connecting pillars, and the energy absorption ability and impact resistance are greatly improved; and in the structural form, the fender and the quay are connected through a rotating system, the fender surface has certain horizontal speed when a ship body is moored alongside, and the fender body can rotate by a certain angle in the speed direction of the ship body and in the direction perpendicular to the pivot direction, so that the friction between the fender and the ship body is reduced, the horizontal load is reduced, and the friction damage to the ship body is reduced.

Description

technical field [0001] The invention relates to a rotatable multi-layer energy-absorbing wharf fender, which belongs to the field of ships. Background technique [0002] Wharf fender is an elastic buffer device installed on the wharf. It is mainly used to reduce the impact on the wharf when the ship is berthing or mooring, and to prevent or eliminate damage to the ship and the wharf. At present, the common fenders include cylinders. Type fender, D type fender, super arch fender and drum type rubber fender etc. These fenders generally use elastic materials such as rubber to absorb energy. The energy absorption capacity is limited, the reaction force is relatively large, and the friction between the fender and the hull is relatively large, which will damage the hull itself and reduce the service life of the fender. . Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a rotatabl...
