Abstract
The invention discloses a flexible cable of a coal cutter. A cable core is formed through twisting of insulating power wire cores, a grounding wire core and control wire groups. Each control wire group is formed through twisting of one stiffener and six control wire cores. Outside the cable core, a reticular nylon reinforcement layer is woven, a layer of inner sheath is wrapped in a pressing manner and a bullet wire reinforcement layer is wound sequentially. An outer sheath is wrapped in a pressing manner at the outmost layer of the cable. The flexible cable of the coal cutter improves significantly the flexibility, high strength and relative slippage of the cable core and improves the service life of the cable.
Description
Technical field
The present invention relates to a kind of cable, refer more particularly to a kind of soft cable of coal mining machine.
Background technology
Due to the demand of Economic Growth to the energy, show the importance of coal in energy structure in China, also accelerate the development of coal mining.Therefore, quickening colliery equipment manufacture technological innovation and structural adjustment are extremely urgent., for controlling short problem of the easily broken core of core, useful life in the supporting rubber covered flexible electric cable for coal mining of coal-winning machine, be at present the key factor of restriction coal-winning machine production efficiency.In cable running, because being subject to the multiple mechanical stress effects such as frequent bending, stretching, easily cause controlling the fracture of core, once control the disconnected core of core; to lose monitoring and protection effect; and cause equipment to shut down, and have a strong impact on user's use, cause very large loss to user.
Summary of the invention
The invention provides a kind of soft cable of coal mining machine, this cable has high flexibility, high strength, resistance to wear and anti-flammability.
Technical solution problem of the present invention adopts following technical scheme: a kind of soft cable of coal mining machine, described power line core conductor is provided with isolation belting layer from inside to outside successively, insulating barrier, semi-conductive layer, gnd conductor is located at place of cable center, its outer one deck semi-conductive layer that extrudes, the dynamic core of described cable core, ground core and control line group is stranded forms, described control line group is strengthened nonwoven fabrics by six roots of sensation control core and the stranded rear wrapped one deck of reinforcement and is formed, described control core is woven with netted nylon reinforced layer outward successively, be extruded with one deck inner sheath, be wound around one deck bullet wire reinforced layer, described control line group outside is extruded with rubber coating layer, the outermost layer of cable is extruded with oversheath.
Described power line core conductor adopts five class tinned copper conductors stranded forming in the same way, is provided with successively isolation belting layer, Ethylene Propylene Terpolymer rubber insulating barrier and semiconductive shielding layer outward at described five class tinned copper conductors.
Described ground wire core conductor adopts five class tinned copper conductors stranded, and described conductor is provided with semiconductive shielding layer outward.
The conductor of described control core is wrapped on high strength fibre and is formed by the zinc-plated soft copper conductor of six classes, and conductor is extruded with perfluoroethylene-propylene insulating barrier outward.
The outer high temperature resistant slip band of wrapped one deck of described perfluoroethylene-propylene insulating barrier.
Described inner sheath, oversheath adopt heavy neoprene to extrude formation.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention is the intensity that improves cable control line core conductor, can add and have higher tenacity fibers, and adopt the structure that tangles again, thereby improve tension and the bending resistance of conductor in conductor.For reinforcement, key performance is exactly its minimum tensile load.Filament material has percentage elongation little (approximately 4%～5%), tensile strength large (about 2500MPa), be far longer than the tensile strength (about 200MPa) of copper, and percentage elongation approximately 3% is far smaller than again the percentage elongation (more than 15%) of copper core.
The present invention, in order ensureing in cable bend, drawing process, to control core and has relative slipping property, controlling the high temperature resistant slip band of wrapped one deck outside core, controls after core stranding, more wrapped one deck reinforcement nonwoven fabrics, increase the relative slipping property of controlling between core.
The present invention adds reinforcement in control core, and can make electric cable for coal mining machine be subject to bending and stretching action time, most of masterpiece is used on reinforcement, reduces the stressed of copper conductor, reduces and controls the possibility that core is pulled off.
The netted structure of cable core external application high-strength nylon fibrage of the present invention, inner sheath adopts chloroprene rubber material, and reinforced layer adopts bullet wire winding arrangement, has not only strengthened the tensile strength of cable, also prevents the impact of the inside of external object to cable.
Brief description of the drawings
Fig. 1 is schematic cross-section and the partial enlarged drawing of cable of the present invention;

Ethylene Propylene Terpolymer rubber insulating barrier, 4. gnd conductor, 5. semiconductive shielding layer, 6. control line group, 7. high strength fibre, 8. control line core conductor, 9. perfluoroethylene-propylene insulation, 10. reinforcement, 11. high temperature resistant slip bands, 12. strengthen nonwoven fabrics 13. coating layers, 14. nylon reinforced layers, 15. inner sheaths, 16. steel wire reinforcing layers, 17. oversheaths.
Embodiment
Below pass through embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment: the coal-winning machine ruggedized cable of the present embodiment, by insulated power core, wire core and control control line group is stranded forms cable core, described cable core is woven with successively netted nylon reinforced layer 14 outward, is extruded with one deck inner sheath 15, is wound around one deck bullet wire reinforced layer 16, and the outermost layer of cable is extruded with oversheath 17; Inner sheath 15, oversheath 17 all adopt heavy neoprene to extrude formation.Nylon fiber network structure outside cable core can be good at integrally combining with inner sheath in the time extruding inner sheath, plays and significantly improves inner restrictive coating intensity, and then improve the overall tensile property of cable.
The conductor of insulated power core closes 1 by five class tinned copper conductor bundles, and it is stranded in the same way that bundle closes conductor strand, and five class tinned copper conductors are provided with isolation belting layer 2, Ethylene Propylene Terpolymer rubber insulating barrier 3 and semiconductive shielding layer 5 outward successively.The conductor 4 of ground core is stranded by five class tinned copper conductors, and conductor is provided with semiconductive shielding layer 5 outward.Control line core conductor 8 is wrapped on high strength fibre 7 and is formed by the zinc-plated soft copper conductor of six classes, and object improves the flexibility of controlling core pull resistance and cable.Conductor extrudes one deck perfluoroethylene-propylene insulation 9 outward, and then the high temperature resistant slip band 11 of wrapped one deck, and object is the slipping property improving between a control core.Control after core and reinforcement 10 strandings at wrapped one deck reinforcement nonwoven fabrics 12, object is the pull resistance of line group of tightening control.At the outer one deck rubber coating layer 13 that arranges of control line group 6, object overcome control core because of cross section little, and premature failure in use.
