Abstract
A 10kV metallic shield weave-reinforced rubber sheathed flexible cable for a coal cutter comprises three power wire cores and three control wire cores. A cable conductor is formed by the power wire cores and the control wire cores and the surface of the cable conductor is sequentially extruded by an inner sheath and an outer sheath; the three power wire cores and the three control wire cores are weaved in an intertwist manner; each power wire core is formed, from inside to outside, by a conductor, a shielding layer and a semiconducting shielding layer; and the control wire core is formed, from inside to outside, by the conductor and an insulating layer. The flexible cable of the utility model is strong in being bending-resistant and wear-resistant and has a 3 to 5 times longer service life than that of a conventional cable.
Description
Technical field
The utility model relates to the coal-winning machine cable.
Background technology
What cable can be subjected to the kindling piece often under mine pounds pressure, extruding, impact, and other mechanical force; add the impact of underground wet environment; present common cable on the market is because tensile strength and tearing toughness are poor; very easily damage; bought potential safety hazard for the operation of coal industry, have much room for improvement.
Chinese patent 201120284504.2,201020519582.1,201020182380.2 all discloses the technical scheme of electric cable for coal mining machine, but its power core, control core are conventional bundle row formula and arrange, easily to the periphery expansion in the long-term bending of cable and wear process, thereby cause distortion of the cable, shorten useful life, and the oversheath of its use is general rubber sleeve, and is wear-resisting all not ideal enough with tensile strength.
Summary of the invention
The utility model is for the deficiencies in the prior art, improved a kind of wear-resistant, tensile strength is high, the metal shielding braided reinforced rubber jacketed flexible cable of coal cutter of long service life.
Key problem in technology of the present utility model is power core and control core weaving formula are integrated, and in the space, fill the glue that blocks water, filled glass fiber between inner sheath and cable conductor, increase its wear-resistant and bending resistance, its concrete technical scheme is: a kind of 10kV metal shielding braided reinforced rubber jacketed flexible cable of coal cutter, comprise some power cores, some control cores, consist of cable conductor, the surface is extruded with inner sheath and oversheath successively, it is characterized in that described power core and control core all are set to 3, both stranded twisted shapes that are woven to, the power core is from inside to outside successively by conductor, screen and semiconductive shielding layer form, and the control core is from inside to outside successively by conductor, insulating barrier forms.Be filled with waterproofing agent in the gap of described power core and the stranded braiding of control core.
Described oversheath is polyurethane.Be filled with glass fibre between described inner sheath and cable conductor.
Described polyurethane oversheath has very strong anti-wear performance and counter-bending anti-tear performance, and feature is applicable to the coal-winning machine cable in the mine.
The beneficial effects of the utility model: coal-winning machine cable of the present utility model, flexural strength is high, and is wear-resistant, and be 3 ~ 5 times of common cable useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
