Abstract
The utility model provides a metal-shielding wrapping reinforced rubber-jacketed flexible cable for a coal cutter. The cable comprises power wire cores, control wire cores, an inner sheath and an outer sheath; each power wire core comprises a power wire core conductor, a power wire core insulating layer and a metal and fiber-braided shielding layer; galvanized steel wires and tinned copper wires are mixed, stranded and wound to form a braided reinforced layer; and the braided reinforced layer can enable the cable to be used in a protection chain plate conveniently and is arranged between the inner sheath and the outer sheath. The cable has the advantages of high strength, high tensile, high wear resistance, oil resistance, heat resistance, environmental protection the like.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable.
Background technology
Electric cable for coal mining machine is divided into power core and controls core, controls the effect that core mainly plays signal monitoring.Coal-winning machine produces very large longitudinal pulling force to cable when walking, and this just requires cable itself should have certain flexibility and counter-bending ability.Due in cable running because being subject to the multiple effect of stress such as frequent bending, coal cinder punching press, various mechanical presses, stretching, easily make cable be damaged, reduce useful life, therefore need layer protective layer to protect cable.Conventional armour mostly is steel wire, can only bearing tension, can not bear extruding force.
Utility model content
Technical problem to be solved in the utility model is to overcome defect of the prior art, and a kind of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable is provided, and has the performances such as high strength, high stretching, high abrasion, oil resistant, heat-resisting, environmental protection.
For solving the problems of the technologies described above; the utility model provides a kind of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable; comprise power core, control core, inner sheath and oversheath; power core comprises power line core conductor, power line core insulation and metal and fibrage shielded layer, is provided with the wrapped reinforced layer that cable is used in protection carrier bar of being convenient to being entwined by zinc-coated wire and tinned copper wire combined beam strand between inner sheath and oversheath.
As further improvement of the utility model, between power line core insulation and metal and fibrage shielded layer, be provided with semiconductive shielding layer, semiconductive shielding layer is the semiconducting rubber that ethylene-vinyl acetate fat and hydrogenation nitrile rubber form.
As further improvement of the utility model, control core and comprise control line core conductor and be extruded in the control line core insulation outside control line core conductor, control line core insulation peripheral hardware auxiliary core conductor and auxiliary core insulation; Control line core conductor is the conductor wire core that the strengthening core of stone dead wire or aramid fiber yarn composition weaves copper strand wire outward; Auxiliary core conductor is that tinned copper wire braiding forms.
As further improvement of the utility model, power line core insulation, control line core insulation and auxiliary core insulation are the insulation rubber of ethylene-octene mixture and ethylene-propylene rubber composition.
As further improvement of the utility model, inner sheath and oversheath are by ethylene-octene compositions of mixtures.
The beneficial effect that the utility model reaches: the utility model provides a kind of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable, and cost is low, serviceability good.There is the performances such as high strength, high stretching, high extruding, oil resistant, heat-resisting, environmental protection, the resistance to bending of shock resistance, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model provides a kind of coal-winning machine metallic shield wrapping bag reinforced rubber sleeve flexible cable,
Comprise three power cores, three controls core, inner sheath 9 and oversheaths 11, power core comprises power line core conductor 1, power line core insulation 2 and metal and fibrage shielded layer 8, is provided with the wrapped reinforced layer 10 that cable is used in protection carrier bar of being convenient to being entwined by zinc-coated wire and tinned copper wire combined beam strand between inner sheath 9 and oversheath 11; Between power line core insulation 2 and metal and fibrage shielded layer 8, be provided with semiconductive shielding layer 7, semiconductive shielding layer 7 is the semiconducting rubber that ethylene-vinyl acetate fat and hydrogenation nitrile rubber form; Control core and comprise control line core conductor 3 and be extruded in the control line core insulation 4 outside control line core conductor 3, control line core insulation 4 peripheral hardware auxiliary core conductors 5 and auxiliary core insulation 6; Control line core conductor 3 is conductor wire cores that the strengthening core of stone dead wire or aramid fiber yarn composition weaves copper strand wire outward; Auxiliary core conductor 5 forms for tinned copper wire weaves; Power line core insulation 2, control line core insulation 4 and auxiliary core insulation 6 are the insulation rubber that ethylene-octene mixture and ethylene-propylene rubber form; Inner sheath 9 and oversheath 11 are by ethylene-octene compositions of mixtures.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
