Description
Technical field
The utility model is about a kind of polyurethane guard rail, particularly to the naval vessel alongside or by help out with money to the time absorb the light polyurethane foam body fender of Impact energy.
Background technology
At present, for prevent the naval vessel alongside or by help out with money to the time bump harbour or hull damaged, generally the side of a ship or harbour parking place are placed glue tire fender, rubber fender or inflation fender and foam fender outside the naval vessel.Glue tire fender is that junked tire is simply bundled absorption naval vessel, back Impact energy, and this fender absorption energy is low, buffering effect is poor, and particularly the answer of bump extruding back is slower, can't satisfy the requirement to fender of Modern Port harbour or naval vessel; Rubber fender is to form casting in particular mold behind natural rubber or the neoprene sizing material hot melt, shortcomings such as weight is big, the design compressive deformation is little, anti-shear ability difference that it exists; The inflation fender utilizes pressurized air to absorb the Impact energy on naval vessel as buffer medium, and there is the counter-force height in it, easily shortcoming such as swarms in; The foam fender is to be buffer medium with the foamed materials, by cystosepiment through tack coat around constituting, again layer around the outside casting of cystosepiment rubber epidermis, shortcoming such as it exists complex manufacturing technology, the easy pull-up of cystosepiment to separate, service life is short.
The utility model content
The purpose of this utility model is to provide that a kind of absorption energy is big, counter-force is low, service life is long, the one-body molded foams fender of the simple polyurethane of manufacture craft, to overcome the deficiency that existing fender exists.
The purpose of this utility model realizes like this, a kind of polyurethane guard rail, described fender includes by the foaming-formed foams of polyurethane, this integrated foams outside face is provided with supporting material layer and carbamide paint layer, a connection piece is preset in described integrated foams inside, and this attaching parts runs through the foams two ends; Described foams two ends are respectively equipped with one and strengthen boss, and described reinforcement boss and attaching parts are fixedly connected.
Described supporting material layer and carbamide paint layer are arranged alternately multilayer.
Described integrated foams are cylindrical; Described supporting material layer is twined by chemical fibre material and constitutes.
Described chemical fibre material is nylon curtain line or polyester thread.
Direction and foams axial direction that described chemical fibre material twines have certain angle.
The angle ranging from 15 degree to 75 degree.
Maintain certain distance between the chemical fibre material that described foam surface is twined.
Described distance is 0.1 millimeter to 5 millimeters.
Described reinforcement boss is made of base, intermediate and the arc part welding that is provided with connecting bore.
The bottom of described base is provided with tapped bore, and described attaching parts two ends are respectively equipped with screw thread, and described attaching parts is spirally connected fixing with the base of strengthening boss.
The utility model compared with prior art, the one-body molded foams fender of polyurethane weight is little, absorb that energy is big, counter-force is low, long service life, manufacture craft is simple, the oil resistance excellence, adaptive capacity to environment is strong, can swim on the water surface, operation is convenient.
Description of drawings
The following drawings only is intended to the utility model done and schematically illustrates and explain, does not limit scope of the present utility model.Wherein,
Fig. 1 is the structural representation of the one-body molded foams fender of the utility model polyurethane.
Fig. 2 is for strengthening the front elevation of boss.
Fig. 3 is for strengthening the birds-eye view of boss.
The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, polyurethane guard rail of the present utility model, comprise by the foaming-formed foams 1 of polyurethane, this integrated foams 1 outside face is provided with supporting material layer and carbamide paint layer 2, a connection piece 4 is preset in described integrated foams 1 inside, and this attaching parts 4 runs through foams 1 two ends; Described foams 1 two ends are respectively equipped with one and strengthen boss 3, and described reinforcement boss 3 is fixedly connected with attaching parts 4.
In the present embodiment, described polyurethane integrated foams 1 are foamings in specific mould (not shown), this mould is the cylindrical housings of hollow, fastened by two and half housings up and down respectively and constitute, two halves housing one side is equipped with hinge, makes the two halves housing open or to fasten by hinge is smooth and easy, both mold ends is welded with flange, the flange center is provided with through hole, conveniently to insert described attaching parts 4, evenly is furnished with the reinforcement rib around the mould outside.
When making described foams 1, at first, by the through hole at both mold ends flange center, in mould, preset described attaching parts 4, in the housing of described fastening, insert polyurethane then and catalyst and other material foams, so that be made into integrated foams 1; After foams 1 moulding, open mould and supporting material layer and carbamide paint layer 2 are set at this integrated foams 1 outside face, last, the reinforcement boss 3 that is fixedly connected with attaching parts 4 is set at foams 1 two ends.
Further, in the present embodiment, as Fig. 1, Fig. 2, shown in Figure 3, the attaching parts that presets described reinforcement boss 3 and foams inside 4 is made by corrosion-resistant steel.Described reinforcement boss 3 is made of base 31, intermediate 32 and arc part 33 welding that is provided with connecting bore 34.Described connecting bore 34 can connect connection chain or rope, makes things convenient for the crewman hand-held when making fender be fixed in harbour or naval vessel by group.
The bottom of described base 31 is provided with tapped bore (not shown), and described attaching parts 4 two ends are respectively equipped with screw thread, and described attaching parts 4 is spirally connected fixing with the base 31 of strengthening boss 3.
Further, in the present embodiment, described supporting material layer and carbamide paint layer are arranged alternately, and two-layer, three layers or multilayer can be set respectively.Described supporting material layer is twined by the chemical fibre material with certain intensity and constitutes; Described chemical fibre material can be nylon curtain line or polyester thread.
To between 75 degree, preferable angle is that 35 degree are to 55 degree at 15 degree for the direction that described chemical fibre material twines and the angle of foams 1 axial direction.
Simultaneously, will maintain certain distance between the chemical fibre material that twine on described foams 1 surface, this distance is between 0.1 millimeter to 5 millimeters, and preferable distance is 0.5 millimeter to 3 millimeters.
Further, in the present embodiment, when foams 1 surface is provided with two-layer above supporting material layer, close on two-layer in, the winding direction of chemical fibre material is different, that is: one deck is that clockwise direction twines, another layer is the anticlockwise direction winding.
