Detailed description of the invention

With reference to Fig. 1, a kind of Novel crane cable of the present utility model is mainly by moving Line of force core, control conductor and be located at core periphery each layer composition.

Specifically, power wire core quantity of the present utility model is four, and it is placed in center, Twisted synthesizing cable.Every power wire core by the first internal conductor 1 and is surrounded on first First insulating barrier 2 of conductor 1 periphery forms.First conductor 1 typically utilizes the 6th class Copper conductor realizes.Four power wire core are just fitting tightly formation by the first insulating barrier 2 Square arrangement, the center of square arrangement is provided with diameter and mates so that gap is basic The first tensile core 3 filled up.First tensile core 3 can be greatly increased power wire core Tensile property, it is to avoid fracture when power wire core uses.

The periphery of square arrangement is extruded with inner liner 4, this inner liner 4 material therefor For Polyurethane Thermoplastic Elastomer rubber.Inner liner 4 plays the work of fixing power wire core With, it is no longer necessary to wrapped band after being provided with this inner liner 4.When implementing, use Suitable mould makes inner liner 4 closely be extruded on cable core, and fills up cable core limit gap i.e. Can.

Inner liner 4 surface is provided with internal shield 5, and internal shield 5 is by proof copper-wire braided layer Form with wrapped aluminum plastic belt.When implementing, first with proof copper-wire braided, its count Not less than 90%, further around one layer of aluminium-plastic tape of bag.

Control conductor 6 is wrapped on internal shield 5, is wound around lay ratio and is not more than 8, Between every control conductor 6, gap is not more than 4.0mm.Control conductor 6 includes second Tensile core 7 and the second tensile core 7 bundle make the second conductor 8 of type and extrude in Second insulating barrier 9 of the second conductor 8 periphery.Second conductor 8 typically uses the 6th class Copper conductor is made, and the second insulating barrier 9 is TPE material.The periphery of internal shield 5 is squeezed Being surrounded by inner sheath 10, control conductor 6 is extruded by inner sheath 10.Implement Time, use suitable mould to make inner sheath 10 closely be extruded on cable core, and fill up Cable core limit gap.The cabling structure design of this utility model cable saves than general cable cabling Away from little, improve flex capability and the tensile property of cable.This utility model cable Inner shielding structure design solves the power wire core of cable and control conductor 6 interferes Problem.

Inner sheath 10 peripheral hardware enhancement Layer 11, this enhancement Layer 11 uses fiber composite core to compile Knitting, count is not less than 95%, had both added the tensile type of cable, and had also ensured electricity The flex capability of cable.Enhancement Layer 11 is externally provided with external shielding layer 12, and external shielding layer 12 is adopted Shielding with proof copper-wire braided, count is not less than 80%, makes control conductor 6 have excellent Different interference free performance.External shielding layer 12 is provided with oversheath 13, and oversheath 13 uses Polyurethane Thermoplastic Elastomer rubber, uses suitable mould, makes oversheath 13 tight Close it is extruded on external shielding layer 12.Elastic polyurethane body rubber is as cable cover(ing) One of optimal material, has excellent thermal oxidation resistance, ozone resistants, weatherability Property, copper wire has the performance that fire-retardant, oil resistant, chemically-resistant etc. are excellent.

The foregoing is only preferred embodiment of the present utility model, be not used to limit This utility model processed, for a person skilled in the art, this utility model is permissible There are various modifications and variations.All within spirit of the present utility model and principle, made Any modification, equivalent substitution and improvement etc., should be included in guarantor of the present utility model Within the scope of protecting.
