Abstract

The utility model discloses a spiral winding formula fender, its by polyurea spraying layer, gumming cord fabric layer, spiral winding's elastic support layer in proper order by forming to interior coaxial fixed mounted outward, spiral winding's elastic support layer is twined by tile foaming board and wire net and is made layer upon layer. Wherein, the foaming board adopts EVA expanded material or PE expanded material, and it is as buffer medium, absorbs the impact energy of boats and ships in the use through its compressing deformation, alleviates the katogene to pier and boats and ships, the wire net both as elastic layer performance cushioning effect, made the fender have certain rigidity as the supporter again, and the fender tip is the toper, and both ends set up connects the stainless steel flange. Wire net and foaming layer no. 1 is worked, and the stress resilience is good, improves the shock resistance of fender, adopt polyurea spraying layer to have good wear resistance, the local defect that supports is avoided as whole bearing structure to the wire net.

Description

A kind of spiral winded type fender

Technical field：

This utility model belongs to fender technical field, is related to a kind of spiral winded type fender, and more particularly to a kind of buffering subtracts Shake ability is strong, and recoverable force speed is fast, makes simple spiral winded type fender.

Background technology：

Fender is a kind of rubber buffer product used on harbour or ship, impact during vessel berth for being slowed down, and is protected Shield ship and harbour are against damages, can be divided into pneumatic rubber fender, solid rubber fender and expanded material filling fender.Inflated type There is the shortcomings of counter-force is high, energy absorption is little, fragile, moulding is difficult expansion in fender.Chinese utility model patent CN2006201524819 discloses a kind of fill type rubber fender, and it includes metal die and abrasive rubber shell, in wear-resisting rubber Closed-cell foam is filled between glue shell and metal die, it has, and energy absorption is big, bounce is low, shock resistance is strong and long service life Etc. advantage.But closed-cell foam is typically all bulk is pasted onto in metal die, complex manufacturing process.Ask to solve this Topic, Chinese utility model patent CN201120515919.6 discloses a kind of light gauge foam filling fender, and it includes foams, leaching Glue carcass and polyureas enhancement layer, the foams be cystosepiment Jing bonding flaggies around forming, but the program eliminates shield Metal die in the middle of the side of a ship, causes fender to lack rigidity supporting structure, while the two schemes are all as bullet using foams Property layer, when impact strength is big, the rebound performance of foams is poor.In addition existing supporting construction all adopts local support, unfavorable In the dispersion and conduction of impulsive force.

The content of the invention：

The purpose of this utility model is to overcome shortcoming present in prior art, seeks a kind of spiral winded type fender, Solve existing fender recoverable force speed slowly, local arranges the problem of rigidity supporting structure.

To achieve these goals, the spiral winded type fender that this utility model is related to, by polyureas sprayed coating, dipped cord Layer of cloth, the resilient support layer of spiral winding are coaxially fixedly mounted with from outside to inside form successively, the resilient support layer of the spiral winding by Tiling foamed board together and steel wire wind make layer by layer.Wherein, foamed board is using EVA expanded materials or PE foaming materials Material, it is absorbed in use the impact energy of ship by its compression, is mitigated to harbour as buffer medium With the destruction of ship；Steel wire both played cushioning effect as elastic layer, and it is certain to have fender as supporter Rigidity, fender end is taper, and two ends arrange connection steel flange.

Further, the spiral winded type fender that this utility model is related to, is prepared using following methods：

(1) foamed board is placed on into steel wire top, both spiral windings is formed into cylinder, sent out during winding Fixing glue is sprayed on bubble plate and steel wire contact surface, annular cutting cylinder two ends, two ends are cut tapered, are made fender and are filled out Fill body；

(2) dipped type cord fabric lock ring is formed into dipped cord layer of cloth 2, so in fender obturator outside made by step (1) Afterwards mounting flange is installed at two ends, then polyureas is sprayed on into the outside of dipped cord layer of cloth 2 as eyelid covering and form polyureas sprayed coating 1.

Compared with prior art, this utility model has advantages below：One is that steel wire and foaming layer one are worked, stress Resilience is good, improves the shock resistance of fender；Two is have good anti-wear performance using polyureas sprayed coating；Three is steel wire As integrated support structure, it is to avoid the defect of local support.

Description of the drawings：

The profile of the spiral winded type fender that Fig. 1 is related to for this utility model.

The principle schematic diagram. of the spiral winded type fender that Fig. 2 is related to for this utility model.

Specific embodiment：

This utility model is described further with reference to specific embodiments and the drawings：

Embodiment 1：

As shown in figure 1, the spiral winded type fender that the present embodiment is related to, by polyureas sprayed coating 1, dipped cord layer of cloth 2, spiral shell The resilient support layer of rotation winding is coaxially fixedly mounted with from outside to inside forms successively, and the resilient support layer of the spiral winding is by being laid in one The foamed board 4 and steel wire 3 for rising winds layer by layer to be made.Wherein, using EVA expanded materials or PE expanded materials, it makees foamed board 4 For buffer medium, the impact energy of ship is absorbed by its compression in use, mitigate to harbour and ship Destruction；Steel wire 3 both played cushioning effect as elastic layer, and made fender have certain rigidity as supporter, Fender end is taper, and two ends arrange connection steel flange 5.

Further, the spiral winded type fender that the present embodiment is related to, is prepared using following methods：

(1) foamed board 4 is placed on into the top of steel wire 3, both spiral windings is formed into cylinders, during winding Spray fixing glue on foamed board 4 and the contact surface of steel wire 3, annular cutting cylinder two ends, two ends are cut tapered, make shield Side of a ship obturator；

(2) dipped type cord fabric lock ring is formed into dipped cord layer of cloth 2, so in fender obturator outside made by step (1) Afterwards mounting flange is installed at two ends, then polyureas is sprayed on into the outside of dipped cord layer of cloth 2 as eyelid covering and form polyureas sprayed coating 1.

Claims (1)

1. a kind of spiral winded type fender, it is characterised in that by polyureas sprayed coating, dipped cord layer of cloth, spiral winding elasticity Supporting layer is coaxially fixedly mounted with from outside to inside forms successively, the resilient support layer of the spiral winding by the foamed board that tiles together and Steel wire winds make layer by layer, and using EVA expanded materials or PE expanded materials, fender end is taper to foamed board, and two ends are arranged Connection steel flange.
