Abstract
The utility model relates to an arched ship fender with small friction coefficients, which comprises a rubber ship fender body. A ship fender surface is arranged on the ship fender body. The utility model is characterized in that a bolt is fixedly connected to the ship fender surface. A super molecule polyethylene guard plate with the thickness of 30 to 40 mm is fixedly connected through buried connecting nuts. Because the thickness of the guard plate is increased, the abrasion strength is raised; because the bolt is used for connection, the arched ship fender can be replaced after damaged; the friction coefficient between the guard plate surface and the ship is smaller than 0.2, the ship berthing horizontal force is obviously decreased, and the service life of the ship fender is prolonged.
Description
Technical field:
The utility model belongs to a kind of harbour protector of harbour, particularly a kind of arch form fender with friction coefficient.
Background technology:
In order to prevent when the ship berthing, boats and ships or wharf structure thing wreck, fender is set on harbour, a kind of arch form rubber fender is wherein arranged, friction factor between the rubber surface of fender and the steel plate of hull is about 0.6, usually because friction factor is excessive, the effect owing to horizontal force in ship berthing causes fender to damage (tearing).At present, in order to reduce skin-friction coefficient, at arch form fender surface (work plane) bonding one deck PE backplate (ultra high molecular polyethylene), but the thickness of this PE backplate generally only is about 10mm, bonding in addition fastness problem, fragile in the use, result of use is relatively poor, and backplate can't be changed when damaging.
Summary of the invention:
The purpose of this utility model provides a kind of friction coefficient arch form fender, improves tear strength, reduces the friction factor between fender surface and the boats and ships, obviously reduces by the ship horizontal force, improves fender application life, and backplate can be changed after damaging.
The purpose of this utility model is achieved in that it comprises the rubber fender body, the fender surface is arranged on the fender body, it is characterized in that: the bolt that is fixedly connected on the fender surface, to bury the coupling nut thickness that is fixedly connected be the ultra high molecular polyethylene backplate of 30-40mm by interior.
Above-mentioned ultra high molecular polyethylene backplate is a polylith.
The utility model has the advantages that: owing to increased the thickness of backplate, improved tear strength, and adopted Bolt Connection, can change after the damage, and the friction factor between backplate surface and the boats and ships is below 0.2, obviously reduces by the ship horizontal force, improved fender application life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is a schematic perspective view of the present utility model.
The specific embodiment:
See Fig. 1-3, concrete structure of the present utility model is as follows: give on the fender surface of arch form rubber fender body 3 burying and fix several attachment bolts 2, have on the ultra high molecular polyethylene backplate 1 that three thickness is 30-40mm and bury the nut connection holes in corresponding with nut, three ultra high molecular polyethylene backplates 1 are buried round nut 4 and are fixedly connected on the fender surface of rubber fender body 3 by interior.
Claims (2)
1, a kind of friction coefficient arch form fender, it comprises the rubber fender body, and the fender surface is arranged on the fender body, it is characterized in that: the bolt that is fixedly connected on the fender surface, to bury the coupling nut thickness that is fixedly connected be the ultra high molecular polyethylene backplate of 30-40mm by interior.
2, friction coefficient arch form fender according to claim 1, it is characterized in that: the ultra high molecular polyethylene backplate is a polylith.
