Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of non-maintaining, long-life rubber foaming fender is provided.

The utility model solves its technical matters and is achieved through the following technical solutions:

A kind of rubber foaming fender is formed by coaxial installing in outer the reaching successively by wearing layer, foamed rubber, enhancement layer and hollow mandrel, is separately installed with the flange that fixes with hollow mandrel two ends at formed fender two ends.

And described wearing layer is cancellated anti tear fiber.

And described foamed rubber is the closed cell foam of natural rubber, buna-S, butadiene rubber, poly-chloroprene rubber, nitrile rubber or EP rubbers, density homogeneous or the structure of density increase from outside to inside.

And described enhancement layer is made of the kiss-coating cord fabric thread, and wherein cord fabric thread is polyamide fibre line or polyester thread, and adjacent kiss-coating cord fabric thread angle is the 40-45 degree.

And described hollow mandrel is made of the foam metal material of filling in beam barrel, the beam barrel, and beam barrel is a rubber, is filled with foam metal material in it.

And the foam metal material of filling is open celled foam aluminium, foamed aluminium magnesium alloy or foamed aluminosilicate alloy in the described beam barrel, and foam metal material and axial wall are fitted closely, and its pore-solids ratio is 60-90%.

And, the uniform projection that is shaped on of described beam barrel outer rim, being shaped in the upper end of this projection can be by the T connector of radial compression.

Advantage of the present utility model and beneficial effect are:

1, the foamed rubber that this rubber foaming fender adopted has the very wide abscess platform that subsides; can almost absorb very big collision energy under the unmodified situation in counter-force; so can effectively protect boats and ships and harbour, be suitable under high seas working or the mal-condition using ship anticollision fender equipment.

2, the foamed rubber stress relaxation speed that this rubber foaming fender adopted is fast, and stress relaxation degree height in the service life that can significantly improve fender, has advantages such as non-maintaining, long service life.

3, this rubber foaming fender design has anti-pulling axle construction and enhancement layer, wearing layer, fender anti-shearing force ability is strong, can be implemented in rough use, wearing layer effectively reduces the friction force of fender, the scratch that prevents the fender surface damages, even surface fracture does not influence its performance and use yet.

4, quill shaft of this rubber foaming fender and foamed rubber are formed in one, and have guaranteed the outstanding anti-shear ability of fender; Quill shaft contains the overvoltage energy-absorbing material, and main rising absorbs the impact energy that moment surpasses foaming body absorption maximum energy part, causes the problem of non-recoverable deformation such as microbubble ruptures to avoid foamed rubber to be compacted.

5, the utility model is simple in structure, and design science has from floatation characteristic and from the overvoltage protection ability, and the energy absorption ability that can improve rubber fender is more than 3 times; Be not subjected to the influence of tidal level height, anti-shearing force is strong, and the big counter-force of energy-absorbing is little, low residual strain, the use tolerance is big, the life-span is long, and maintenance free, especially being fit to the use that mal-condition is gone ashore and gone to dock by ship or ship, is a kind of really round-the-clock, non-maintaining desirable boats and ships anticollision fender equipment.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of rubber foaming fender, fender 2 is formed by coaxial installing in outer the reaching successively by wearing layer 3, foamed rubber 5, enhancement layer 4 and hollow mandrel 6, be separately installed with on 1, two flange of flange that fixes with hollow mandrel two ends in formed fender both sides the suspension ring (figure does not illustrate) that are used for lifting all are installed.The hollow mandrel is made of the foam metal material 8 of filling in beam barrel 10, the beam barrel, beam barrel is made by elastomeric material, foam metal material of filling is open celled foam aluminium, foamed aluminium magnesium alloy or foamed aluminosilicate alloy in it, and foam metal material and axial wall are fitted closely, and its pore-solids ratio is 60-90%.In the uniform projection 9 that is shaped on of beam barrel outer rim, being shaped in the upper end of this projection can be by the T connector 7 of radial compression; The radius of hollow mandrel is less than 15% of the fender radius, its two ends be shaped on can with the screw thread of the stainless flange connection of fender.

Foamed rubber mainly plays compressive deformation and absorbs collision energy; Enhancement layer works to improve the fender anti-shearing force, eliminates residual strain; Wearing layer has anti-puncture, prevents tearing wear-resistant effect, mainly protects fender to avoid wearing and tearing and scratch.

Wearing layer includes cancellated anti tear fiber, for example the terylene or the polyamide of high molecular weight polyethylene fiber or PU coating.

Foamed rubber is the closed cell foam of natural rubber (NR), buna-S (SBR), butadiene rubber (BR), poly-chloroprene rubber (CR), nitrile rubber (NBR) or EP rubbers (EPM EPDM), and its micropore hole mean diameter is less than 50 microns; The density of foamed rubber can be for homogeneous, also can be that density increases structure from outside to inside, and density range is from 80Kg-380Kg/m3.

Can add reinforced filling in the foamed rubber, for example the abrasion resistant carbon black of small particle diameter.

Enhancement layer mainly is made of the kiss-coating cord fabric thread, and wherein cord fabric thread can be polyamide fibre line or polyester thread, and the composition of kiss-coating is mainly the elastomeric compound of natural rubber or natural rubber and other rubber and the compound of functional filler; The cord fabric thread of every adjacent two layers becomes 40-45 degree angle in the enhancement layer, adopts the adhesives with self-defoaming function to be bonded together between each layer, and guaranteeing to combine closely between each layer does not have bubble.

The structure of the hollow mandrel of rubber foaming fender has and prevents the structure that spurs vertically, can be compressed on the vertical axial direction again simultaneously.

This fender can swim in the water surface.
