Embodiment Construction

[0029] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0030] A rubber foam fender. The fender 2 is composed of a wear-resistant layer 3, a reinforcing layer 4, a rubber foam body 5 and a hollow mandrel 6. Flanges 1 fixed to the two ends of the hollow mandrel are respectively installed on the sides, and suspension rings (not shown) for hoisting are installed on the two flanges. The hollow mandrel is composed of a shaft cylinder 10 and a metal foam material 8 filled in the shaft cylinder. The metal material is closely attached to the shaft wall, and its porosity is 60-90%. Protrusions 9 are evenly distributed on the outer edge of the shaft cylinder, and a T-shaped head 7 that can be radially compressed is formed on the upper end of the protrusion; the radius of the hollow mandrel is less than 15...

Abstract

The invention relates to a rubber foaming fender, which comprises a wear-resisting layer, a reinforcement layer, a rubber foaming body and a hollow mandrel which are coaxially and fixedly arranged from the outside to the inside, and the two ends of the fender are provided with flange plates which are fixed with the two ends of the hollow mandrel respectively. The rubber foaming fender has simple structure, scientific design, self-floatation characteristic and self overpressure protection ability, can improve the absorption ability of the floating fender by over three times, does not be affected by the tidal level, has high anti-shearing force, large energy absorbing, small counter force, low residual strain, large using tolerance, long service life, and no need of maintenance, is particularly suitable to be used when two ships are drawn together or the ship docks under severe conditions, and is an all-weather and maintenance-free ideal anti-collision ship fender device.

Description

technical field [0001] The invention belongs to the field of ships, and relates to anti-collision equipment when a ship is docked with a ship or a dock, in particular to a rubber foam fender. Background technique [0002] The anti-collision fenders currently used in ship-to-ship and ship-to-dock mainly include inflatable rubber fenders, solid rubber fenders and polyurethane fenders. Inflatable rubber fenders use closed compressed gas as the collision buffer medium, so air leakage and fear of pinching are their biggest disadvantages; solid rubber fenders are mainly installed on docks or ship sides, and have disadvantages such as high reaction force and small compression deformation. When installing fenders at the wharf, it is necessary to install high and low water levels and rubber fenders in vertical and horizontal directions according to the water level and shear force, which requires a lot of manpower and material resources. Polyurethane fender is a new type of fender th...
