Abstract
The utility model provides a rubber fender beam having curved groove at the bottom for the protective system of the port and the dock. A curved groove is provided between the outer porches of the inner imbedding flange plates at the bottom and the end of the original rubber barrel, then the fender beam is formed. The absorbing capacity / counter force of the fender beam and the height value of the product are raised 15% so as to lower the engineering cost of the equipment. And the compressing deformation of the fender beam is raised to 52.5% from 47.5% of the original technique under the situation of the counter force unchanging. Due to good stress dispersibility of the product, the fender beam is provided with superior durability, meanwhile, it is provided with small change of the slanted docking performance, and is suitable for use in large, medium and small-sized docks and boats.
Description
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 drum type rubber fender device of good springiness.This device is formed by burying flanged plate in rubber bodies and its end.But the shortcoming that this device in use also exists is: the rubber bodies root is the right angle, not only and to bury between the flanged plate adhesion area in the end little, intensity is low, insecure, and because stress is concentrated, when ship alongside, mooring or shifting berth, when particularly the harbour of the large and medium-sized deep-water berth more than 10 tons is installed and used, the environmental forces effect that wind-engaging, stream, wave cause, the huge bump of boats and ships often buries between the flanged plate shear failure in rubber bodies root and its end or knocks.Application life is short, and is very dangerous, and maintenance is also difficult.
The purpose of this utility model is to be port terminal protecting system, the drum-type rubber fender material that provides a kind of improved root that arcuate furrow is arranged between particularly large and medium-sized boats and ships and the dock structure.Not only functional performance is good, the life-span is long, and construction costs is low.
The purpose of this utility model is achieved in that it is formed by burying flanged plate in arcuate furrow, rubber cylindrical shell and the end.Its main practice is: bury in the root of former rubber cylindrical shell and its end and establish an arcuate furrow between the flanged plate outer.Concrete process for making is: described rubber cylindrical shell is selected excellent spring for use, and 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; Bury flanged plate in the described end, adopt thick sheet metal to be processed into sandblast scale removal, brushing layer of adhesive; Machine-shaping sulfuration and become one in mould then.
The utility model is established an arcuate furrow because only need to bury between the flanged plate outer in the root of former rubber cylindrical shell and its end.So compare with former technology: E/RH(energy absorption/counter-force goods height) value improves 15%.In other words, adopting the utility model is consistent than the product of small-sized with the properties of product of using the big specification of former technology.Thereby reduction construction costs.Under the constant situation of counter-force, compressive strain brings up to 52.5% from former technology 47.5%.Because goods stress dispersive property is good, makes it have superior durability.Also have characteristics such as oblique alongside performance variation is little simultaneously.
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 flanged plate in 1 camber groove, 2 rubber cylindrical shells, 3 ends among the figure.The main practice of this rubbing strake is to bury to establish an arcuate furrow 1 between the outer of flanged plate 3 and form in the root of former rubber cylindrical shell 2 and its end.Concrete manufacture craft process is as follows:
Rubber cylindrical shell 2 shown in the figure is selected excellent spring for use, the tearing toughness height, and corrosion resistant, wear-resisting natural rubber or synthetic rubber or both and usefulness are with the mixing sizing material of making of other rubber chemicals;
Bury flanged plate 3 in the end described in the figure, adopt thick sheet metal or other metal material processing to make, the sandblast scale removal, brushing layer of adhesive (market is on sale) places in the mould;
Then the heating of above-mentioned sizing material is placed described in-mold molding, sulfuration and become one.The specification of its mould is that the specification according to harbour actual needs goods designs processing and fabricating.
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.
Root of the present utility model has the drum-type rubber fender material of arcuate furrow, is applicable to large, medium and small type harbour and boats and ships.
