Abstract

A moulding packed rubber fender comprises a metal tube core. The two ends of the metal tube core are respectively welded with two inner flange plates. The two flange plates are respectively connected with the corresponding outer flange plates fixedly through the bolts. The two outer flange plates are respectively provided with metal flying rings. The metal tube core is coated with a sub used as agglomerant. The sub used as agglomerant is coated with a liquid rubber layer. The liquid rubber layer is filled with blind hole foam filling layer according to the designed shape. The two ends of the blind hole foam filling layer are respectively fixedly connected with the flange plates on the two ends of the metal tube core. The blind hole foam filling layer is coated with a liquid polyurethane rubber layer and the liquid polyurethane rubber layer is wrapped with grid cloth. The grid cloth is moulded with liquid polyurethane rubber layer and then become finished goods after finalizing the design. The utility model has the advantages of large absorbing energy, low rebound force, powerful anti wallop, long service life, and fulfills the anti collision protection between the ship and the dock, and between the ship and ship, and saves the energy, lowers down the producing cost.

Description

Casting type filled rubber fender

Technical field

The utility model relates to a kind of anticollision device, particularly relates to a kind of float type rubber fender that is applicable to harbour, rubber fender that boats and ships use.

Background technology

In order to prevent that boats and ships and harbour and building from being destroyed, need between boats and ships and harbour, between boats and ships and the boats and ships fender be set and be protected, junked tire is adopted in traditional protection more.Along with the development of Modern Port and maritime industry, tonneaux de jauge is increasing, and the berth is increasing.The General Purpose Rubber fender can not satisfy the safety of ship demand of reaching port,, therefore employed rubber fender is also increasing.

At present, the domestic and international float type rubber fender of producing is an inflatable rubber fender mostly, exists the counter-force height, energy absorption is little, fragile, and moulding is difficult for shortcomings such as excessive.Its inner utilization pressurized air is as buffer medium, and cold tolerance is poor, day cold easy gas leakage.After the gas leakage, the fender floatability is bad, can not adapt to tidal range and change, and energy absorption reduces greatly, and product is easily torn.When using inflatable rubber fender, need often to observe, inflation has brought a lot of troubles to applying unit at any time, and replacing is safeguarded also very difficult.Can not satisfy present harbour and shipping work demand.

Summary of the invention

The purpose of this utility model is the defective that exists at above-mentioned prior art, and a kind of usefulness rubber fender that inner packing material is made is provided.This product has that energy absorption is big, bounce is low, and anti-impact force is strong, and long service life can be made the ultra-large type goods.

The technical scheme that adopts is:

Casting type filled rubber fender comprises metal die.There is inner flange at metal die two ends solid welding respectively, and two inner flanges are respectively by the outward flange dish captive joint of bolt with corresponding setting.On two outward flange dishes, be fixed with the metal suspension ring respectively.On metal die, be coated with the glue-line of using as adhesive agent, on boning, be coated with the liquid rubber layer with glue-line, being filled with the closed-cell foam filling bed by setting shape on the liquid rubber layer, captives joint with the flange at metal die two ends respectively in closed-cell foam filling bed two ends.Applying liquid poly-urethane rubber layer is arranged with grid cloth on the liquid polyurethane rubber layer on the closed-cell foam filling bed, at grid cloth top casting liquid polyurethane rubber layer, is finished product after the typing.

Shapes such as that the utility model can be made into is cylindrical, circular, oval, sphere.

The manufacture method of casting type filled rubber fender is: will coat bonding glue on the metal die, on boning, coat liquid rubber again with glue, twine closed-cell foam then, and make it to reach the rubber fender shape and the size of setting, constitute the closed-cell foam filling bed, the two ends of closed-cell foam filling bed are connected with the flange cementation at metal die two ends respectively, on the closed-cell foam filling bed of moulding, coat liquid polyurethane rubber again, and twining grid cloth on this poly-urethane rubber, at last, be finished product after the typing being wound with on the closed-cell foam filling bed of grid cloth by setting thickness cast polyurethane rubber.This production technology is saved the sulfidization molding technological process.

The utlity model has and absorb that energy is big, bounce is low, anti-impact force is strong, long service life, particularly is suitable for making the ultra-large type fender, can satisfy between boats and ships and the harbour, the anticollision between boats and ships and the boats and ships protects.Can make the ultra-large type goods,, solve the difficult problem of ultra-large type goods sulfuration, save the energy, and reduced manufacturing cost owing to saved the sulfidization molding technological process during fabrication.

The specific embodiment

Casting type filled rubber fender comprises metal die 1, as steel pipe.2, two inner flanges 2 of inner flange are set respectively at the two ends of metal die connect by a plurality of bolt with the outward flange dish 3 of two inner flanges, 2 corresponding settings respectively, solid welding is connected with metal suspension ring 4 on each outward flange dish 3.On metal die 1, be coated with the glue-line of the usefulness that is used to bond, on the glue-line that is coated with the usefulness that is used to bond on the metal die 1, be coated with liquid polyurethane rubber layer 5 again, on this liquid polyurethane rubber layer 5, twine closed-cell foam filling bed 6 then.The requirement of the layer of closed-cell foam of filling is the fender shape that reaches designing requirement.Closed-cell foam filling bed two ends are connected with two inner flange 2 cementations respectively.After the closed-cell foam filling moulding, applying liquid poly-urethane rubber on the closed-cell foam filling bed twines grid cloth 7 on the liquid polyurethane rubber of this coating, is finished product in 8 typings of grid cloth 7 top casting liquid polyurethane rubbers at last.

Claims

1, casting type filled rubber fender, comprise metal die (1), be set with inner flange (2) respectively at metal die (1) two ends, two inner flanges (2) pass through bolted connection with the outward flange dish (3) of the corresponding setting of two inner flanges (2) respectively, be installed with metal suspension ring (4) on the outward flange dish (3), it is characterized in that on metal die (1), being coated with the glue-line of using as adhesive agent, on the glue-line of this bonding usefulness, be coated with liquid polyurethane rubber layer (5), go up by setting shape winding closed-cell foam filling bed (6) at liquid polyurethane rubber layer (5), closed-cell foam filling bed (6) two ends are connected with cooresponding inner flange (2) cementation respectively, on closed-cell foam filling bed (6), be coated with liquid polyurethane rubber, twine again and go up grid cloth (7), be cast with liquid polyurethane rubber layer (5) at grid cloth (7) top-pour, be finished product after the typing.
