Abstract

The utility model provides an improved arch-shaped rubber material for protecting ship side for the protective system of the port and the dock. The inner contour of the arch-shaped rubber body of which the bottom part is imbedded with a reinforcement plate is designed to two sections, the upper section is M-shaped, and the lower part is an oblique line. The upper section of the outer contour is designed to a vertical line so that the thickness of the rubber oblique body is reduced, and the distance of the inner oblique body is enlarged. So compared with the original technique, the device has reasonable structure, easy manufacture, material saving, anti-breakage and long service life, and the stress concentration phenomenon of the compressing head obtains the improvement in the process of using, and the ratio value of the absorbing capacity and the counter force and the height is raised by 23.5%. The material for protecting ship side is suitable for use in medium and small-sized docks and marine vessels.

Description

Arch-shape rubber material for protecting ship side

The utility model relates to port terminal protecting system, a kind of damping device that is provided with between boats and ships and the dock structure.

Before the utility model, suffer damage, need between boats and ships and dock structure, to take safeguard procedures, a kind of liner is set for preventing boats and ships or wharf structure thing.The common practice is: generally adopt wooden unit, junked tire and steel rubbing strake etc.These are concerning the very little boats and ships of traditional harbour and displacement, and because of hull framing is sturdy, shell is abundant, can reach the opposing bump and avoid the purpose damaged.But the development trend of modern ships and harbour is: oil tanker, bulk goods wheel and container ship occur in succession, be to increase the delivered payload capability and the headway of boats and ships, shell is thin, external drum, big displacement, drinking water and wharf structure require pile foundation pier formula structure and shift to the deep-sea deeply.Therefore, the safeguard procedures of transmitting are far from suitable, it can not provide enough degrees of safety, often makes the wounded or heavy damage of boats and ships and harbour and liner, brings difficulty for maintenance and handling operation, and existing sark corrosion resistant, wear no resistance, application life is short, needs often to change, though the steel rubbing strake is durable in use, but shortcoming is: hull sustains damage easily, and it is also difficult to damage the back maintenance.

For addressing the above problem, once the someone had proposed a kind of V-type rubber fender material of excellent spring, and this rubbing strake is made up of the rubber bodies of burying the metal reinforcement plate in the bottom, two ends.But the weakness that this rubbing strake in use also exists is: the V-type body structure, and the inside and outside contour line is straight line, and italic is abundant, and interior italic spacing is little, outer upper surface is narrow, and when ship alongside, mooring or shifting berth, face pressure head portion stress is concentrated, the compression body outward bulge, be out of shape little, the counter-force height, energy absorption is low.The particularly boats and ships environmental forces effect that wind-engaging, stream, wave cause when mooring, when the harbour direction was moved, because shear strength is low, the fender body very easily produced shear failure, and application life is short.

The purpose of this utility model is to provide a kind of improved arch form rubber fender material for port terminal protecting system.It is not only rational in infrastructure, makes easily, save material, and performance is good, and counter-force is low, energy absorption height, anti-shearing destruction, long service life.

The purpose of this utility model is achieved in that it comprises that the main practice of burying stiffening plate, this rubbing strake in arch shaped rubber body and the bottom is: the end face inner outline of described arch shaped rubber body is divided into two sections, and epimere is a M shape, and hypomere is an oblique line; The outer contour epimere is a vertical line.Concrete process for making is: is processed into thick sheet metal burying stiffening plate in the described bottom earlier, and the sandblast scale removal, the brushing layer of adhesive places in the mould; Above-mentioned arch shaped rubber body excellent spring, natural rubber that tearing toughness is high or synthetic rubber or both and usefulness are with the mixing sizing material of making of other rubber chemicals again; Place above-mentioned in-mold molding sulfuration to become one by heating.

The utility model only needs the arch shaped rubber body exterior contour that buries stiffening plate in the existing bottom is changed into above-mentioned shape, make rubber italic reduced thickness, interior spacing increases, and also can reduce the product height, so with former technology ratio, not only rational in infrastructure, easy to manufacture, save engineering cost, and article construction has higher stress dispersiveness in using compression process, the ratio of energy absorption and counter-force and height has improved 23.5%, anti-destruction, long service life.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof:

Fig. 1 is a kind of concrete structure sectional view of this rubbing strake.

Bury stiffening plate, the 3rd in 1 arch shaped rubber body, 2 bottoms among the figure, the epimere of outer contour, 4 is the epimere of inner outline, the 5th, the hypomere of inner outline.The main practice of this rubbing strake is: bury stiffening plate 2 in the bottom of rubber bodies 1, the inner outline of rubber bodies 1 end face is divided into two sections, and epimere 4 is a M shape, and hypomere 5 is an oblique line shape, and the epimere 3 of outer contour is a vertical line.Concrete manufacture craft process is as follows:

Burying stiffening plate 2 in the bottom shown in the figure, be processed into earlier with thick sheet metal, the sandblast scale removal, brushing layer of adhesive (market is on sale) places in the mould; Again the arch shaped rubber body shown in the figure 1, use excellent spring, natural rubber that tearing toughness is high or synthetic rubber or natural rubber and synthetic rubber and usefulness with the mixing sizing material of making of other rubber chemicals, place above-mentioned in-mold molding sulfuration to become one by heating.Described die size is according to the specification of harbour actual needs goods, designs and produces with metal material.

The use and the working condition of this rubbing strake are: according to the factors such as the angle of pulling in to shore of harbour form, Ship's Dimension and boats and ships, and be chosen to be lateral arrangement, promptly along the length direction of harbour, or vertically arrange, promptly along the harbour short transverse, its spacing should be able to guarantee that boats and ships can not strike on two bulkhead walls between the rubbing strake, use bolt when alongside.When ship berthing, mooring or shifting berth, utilize the build of this rubbing strake and effective Impact energy that rubber compressive strain absorbs boats and ships, prevent that boats and ships and harbour from suffering damage, protection harbor work handling operation safety.

Arch rubber fender material of the present utility model is applicable to medium and small harbour and boats and ships.

Claims (1)

1, a kind of arch form rubber fender material, it has the arch shaped rubber body that buries stiffening plate in the bottom, two ends, and it is characterized in that: the inner outline of arch shaped rubber body end face is divided into two sections, and hypomere is oblique line, and epimere is M shape, and the outer contour epimere is a vertical line.
