Description

M-type rubber protecting board device for ships to draw alongside

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, for preventing that boats and ships or wharf structure thing from suffering damage, need between boats and ships and dock structure, to take safeguard procedures, a kind of liner is set, generally adopt waddy, plank, reed fabric, kid, rattan group, rope made of hemp group and waste and old air-inflation tyre and steel fender bar 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 of modern ships and harbour is: oil tanker, bulk goods wheel and box ship occur in succession, for increasing the delelivered payload capability and the route speed of boats and ships, reduce the boats and ships deadweight, consumption of fuel and shipbuilding cost make hull develop to lightness, and shell is thin, external drum, big displacement, deep draft and wharf structure require pile foundation pier formula structure and shift to the deep-sea, and the loading and unloading of dangerous freight also must be carried out in the bleak and desolate marine site away from seashore.Therefore traditional safeguard procedures are far from suitable, and it can not provide enough degrees of safety, often causes the wounded or havoc of boats and ships and harbour and liner, bring difficulty for maintenance and loading and unloading operation, and the economic loss that causes also is huge.Have the liner corrosion resistant simultaneously now, wear no resistance, service life is short, needs often to change.Though the steel fender bar is durable in use, its shortcoming is that hull sustains damage easily, and it is also difficult to break the back maintenance.

Be head it off, the our factory has proposed a kind of arch form rubber fender device of excellent spring, and it is made up of bolt hole, the strong plate of lining and rubber bodies.But in use also there is such weakness in this device, its arch form body structure, and italic is abundant, and interior italic spacing is little, outer upper end face width, face pressure value reaches 960KN/cm when ship berthing, mooring or shifting berth ², the compression body outward bulge is out of shape for a short time, and counter-force is big, and energy absorption is little.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 fail in shear.

The purpose of this utility model is that a kind of improved M type rubber fender device will be provided.It not only when alongside, mooring or shifting berth face press little; compressive deformation is big; counter-force is low or do not have a counter-force; energy absorption is big; the shear strength height; huge bump in the time of resisting ship berthing effectively, protection ship and harbour exempt from and damage and the safety of harbor work's loading and unloading operation, and have advantages such as corrosion resistant, wear-resisting, ageing-resistant and long service life.Simultaneously simple in structure, easy to manufacture, save raw MAT'L and easy for installation.

The purpose of this utility model is achieved in that this device is made up of bolt hole 1, stiffening plate 2, rubber bodies 3, upper groove 4 and inner groovy 5.It is characterized in that: upper surface outside the rubber bodies 3 of existing arch form rubber fender device, along the centerline length direction a straight-though groove 4 is arranged, have three straight-though grooves 5 along its length at least at inner plane.Main way is: stiffening plate 2 adopts metal sheet to be processed into, the sandblast scale removal, and coating layer of adhesive and one deck contain the rubber cement of adhesives, are coated in the two ends base of rubber bodies 3.Its rubber bodies 3 adopt natural rubbers or neoprene or natural rubber and neoprene and in order to and the mixing sizing material that forms of other rubber chemicals, by heat refining, roll and be cut into film.Machine-shaping on mould then forms with the sulfuration of hydraulic compressor matched moulds.

The utility model is because only need upper surface outside the rubber bodies of existing arch form rubber fender device, along the centerline length direction a straight-though groove is arranged, have three straight-though grooves at least along the inner plane length direction, make the rubber bodies reduced thickness, interior spacing increases, so it is simple in structure, easy to manufacture.Compared with the prior art: save raw MAT'L 10%, press for a short time one times by deck, compression body is inwardly roused, and allows deflection to improve 10%, and energy absorption improves 10%, and counter-force hangs down 20%, the shear strength height.Therefore; the utility model not only can be resisted wind, stream, wave effectively and cause the environmental forces effect when ship alongside, mooring or shifting berth; the huge bump that boats and ships pull in to shore, protection ship and dock safety and exempt from damage, but also have advantages such as corrosion resistant, wear-resisting, ageing-resistant and long service life.It is all very convenient that replacing is installed simultaneously.

Fig. 1 is the birds-eye view of a kind of concrete structure of the utility model.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

Among the figure 1, bolt hole; 2, stiffening plate; 3, rubber bodies; 4, upper groove; 5, inner groovy.

Details are as follows for embodiment:

The use and the service condition of this device are: the factors such as the angle of pulling in to shore according to harbour form, tidal range, ship dimensions and boats and ships are chosen to be vertical layout promptly along harbour short transverse or vertical the layout promptly along the harbour length direction, its spacing should be able to guarantee that boats and ships can not strike on two bulkhead walls between the ship side protector, use bolt anchoring when alongside.When ship berthing, mooring or shifting berth, utilize rubber fender device build and rubber compressive deformation to absorb effective Impact energy of boats and ships, prevent that boats and ships and harbour from suffering damage, protection harbor work loading and unloading operation safety.

The concrete process for making of this device is:

Bolt hole 1 among Fig. 2 and stiffening plate 2 adopt steel plate to be processed into, the sandblast scale removal, coating layer of adhesive (market sale), at room temperature dry 30 minutes, brushing one deck contains 10% adhesives (sizing material: the rubber cement of gasoline=1:6) is coated on after the natural seasoning in the two ends base of rubber bodies 3 again.

Rubber bodies 3 among Fig. 2 is selected good springiness, corrosion resistant, wear-resisting, ageing-resistant and elastomeric material that tear strength is high for use, for example natural rubber or neoprene or natural rubber and neoprene and in order to and the mixing sizing material that forms of other rubber chemicals.Sizing material is cut into film by heat refining, calendering in use.This elastomeric material also can be made of plastic.

Upper groove 4 among Fig. 2 upper surface outside rubber bodies 3, straight-through along the processing of centerline length direction.

Inner groovy 5 among Fig. 2 is at rubber bodies 3 inner planes, along its length three all processing is straight-through, its grooves on two sides size is wanted symmetry.

Machine-shaping on mould then forms with the sulfuration of 500～1000 t hydraulic press matched moulds.The condition of sulfuration is: steam pressure is 1～5kg/cm ², the time is 60～4000 minutes.Described mould is to design processing and fabricating according to goods requirement specification.

M type rubber fender device of the present utility model is applicable to medium and small harbour and boats and ships.

Claims (1)

1, boats and ships pull in to shore with M type rubber fender device, and it is made up of stiffening plate 2 and rubber bodies 3, it is characterized in that:

There is a straight-though groove 4 a, described rubber bodies 3 outer upper surfaces along the centerline length direction;

B, described rubber bodies 3 inner planes have three straight-though grooves 5 along its length at least.
