Abstract
The utility model discloses a coal cutter reinforced cable. A cable core is formed by stranding an insulating power line core, a ground wire core, and a control wire core group. A netted nylon reinforced layer, is woven outside the cable core. An inner sheath is extruded outside the netted nylon reinforced layer. A bullet wire reinforced layer is winded or woven outside the inner sheath. An outermost layer of the cable is extruded with an outer sheath. The high-strength and good toughness bullet wires are used as the reinforced layer in the cable, thereby effectively offsetting shear forces and bending forces on the cable caused by frequently turning around, bending and moving excavation equipment, thereby obviously prolonging service life of the cable.
Description
Technical field:
The utility model relates to a kind of coal-winning machine ruggedized cable.
Background technology:
As everyone knows, China is the big country of a rich coal resources, coal is one of important energy of China, along with the develop rapidly of China's economy, country is constantly soaring to the demand of the energy, has accelerated the exploitation of coal resources, this also must drive and be used for the cable development that the coal mining equipment dynamic connects use, and the coal resources of China due to the frequent movement of extractive equipment, produce powerful shearing force, bending force to the cable that connects extractive equipment mainly underground.Common coal-winning machine is not taked strengthening measure with cable, and powerful shearing force can cause the restrictive coating of cable and insulating barrier to break, and bending force can cause the conductor thread core of cable to fracture frequently.How to reduce powerful shearing force, bending force, extruding force effect that extractive equipment produces cable and will be that to produce long-life cable crucial.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of possess high strength, anti-bending, tension, wear-resisting, fire-retardant high-performance coal-winning machine ruggedized cable.
The utility model technical solution problem adopts following technical scheme:
A kind of coal-winning machine ruggedized cable, by the insulated power core, core and control that the core group is stranded consists of cable core, described cable core is woven with successively netted nylon reinforced layer outward, is extruded with one deck inner sheath, is wound around or is woven with one deck bullet wire reinforced layer, and the outermost layer of cable is extruded with oversheath.
Described inner sheath, oversheath adopt heavy haloflex rubber to extrude formation.
The conductor of described insulated power core is closed by five class tinned copper conductor bundles, and it is stranded in the same way that bundle closes the conductor strand, is provided with successively isolation belting layer, Ethylene Propylene Terpolymer rubber insulating barrier and semiconductive shielding layer outside described five class tinned copper conductors.
The conductor of described ground core is stranded by five class tinned copper conductors, and described conductor is provided with semiconductive shielding layer outward.
The insulated wire cores outside of described control core group is extruded with the rubber coating layer, and the conductor of described insulated wire cores is wrapped on high strength fibre by the six zinc-plated soft copper conductors of class and consists of, and conductor is extruded with Ethylene Propylene Terpolymer rubber insulating barrier outward.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model utilizes the bullet wire of high strength, good toughness as the reinforced layer of cable, can effectively offset to answer that extractive equipment frequently reverses, crooked mobile shearing force, the bending force that cable is produced, thereby obviously extend the useful life of cable.
Power line core conductor of the present utility model and ground core adopt the five zinc-plated soft copper tow strand of class conductor structures, the control line core conductor adopts and to surpass the six zinc-plated soft copper conductors of class and be wrapped in structure on high strength fibre, extrudes the rubber coating layer after many insulated pilot wire cores are stranded; The netted structure of cable core external application high-strength nylon fibrage, inner sheath adopts heavy haloflex rubber material, and reinforced layer adopts bullet wire braiding or winding arrangement, and oversheath adopts heavy haloflex rubber material to make.It is to have to integrate high strength, anti-bending, tension, wear-resisting, fire-retardant, soft high performance cable, applies to specially the high-performance electric cable for coal mining machine that mine shearer power supply and similar devices connect use.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 high strength fibre; 2 power cores; 3 five class tinned copper conductors; 4 isolation belting layers; 5 Ethylene Propylene Terpolymer rubber insulating barriers; 6 semiconductive shielding layers; 7 ground cores; 8 control the core group; The 9 six zinc-plated soft copper conductors of class; 10 coating layers; 11 nylon reinforced layers; 12 inner sheaths; 13 steel wire reinforcing layers; 14 oversheaths.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: the coal-winning machine ruggedized cable of the present embodiment, by insulated power core 2, core 7 and control that core group 8 is stranded consists of cable core, described cable core is woven with successively netted nylon reinforced layer 11 outward, is extruded with one deck inner sheath 12, is wound around or is woven with one deck bullet wire reinforced layer 13, and the outermost layer of cable is extruded with oversheath 14; Inner sheath 12, oversheath 14 all adopt heavy haloflex rubber to extrude formation.The outer nylon fiber network structure of cable core can be good at integrally combining with inner sheath when extruding inner sheath, plays significantly improving inner restrictive coating intensity, and then improves the whole tensile property of cable.
In specifically arranging, the conductor of insulated power core 2 is closed by five class tinned copper conductor 3 bundles, and it is stranded in the same way that bundle closes the conductor strand, is provided with successively isolation belting layer 4, Ethylene Propylene Terpolymer rubber insulating barrier 5 and semiconductive shielding layer 6 outside five class tinned copper conductors.The conductor of ground core 7 is stranded by five class tinned copper conductors 3, and is provided with semiconductive shielding layer 6 outside conductor, and the purpose that arranges like this is to improve the whole vertically stretching resistance of cable power core.The insulated wire cores outside of controlling core group 8 is extruded with rubber coating layer 10, and to be to have overcome the control core little because of the cross section for the purpose of setting like this, and premature failure in use.Wherein the conductor of insulated wire cores is wrapped on high strength fibre 1 by the six zinc-plated soft copper conductors 9 of class and consists of, and conductor is extruded with Ethylene Propylene Terpolymer rubber insulating barrier 5 outward.
