Technical field
The utility model relates to a kind of cable, is a kind of flexible cable for coal mining machine specifically.
Background technology
Control core in the electric cable for coal mining machine that coal industry is used mainly plays the effect of transmission of control signals, it is the crucial matching component of coal-winning machine, but because electric cable for coal mining machine is frequent crooked and mobile when work, easily be subject to external force or touch the foreign matter injury, cause cable to be in the state of going to work braving one's illness, be prone to the phenomenon of control core fracture, the control core is in case disconnected core, can't correctly export electromagnetic signal, and cause equipment to stop operating.Therefore the easily broken core of control core, the useful life in the soft cable of coal mining machine short be the key factor that restricts at present coal-winning machine production efficiency.
Simultaneously; equipment monitor core in the cable is undertaken the function that realizes the continuous monitoring of whole system integrality; when system meets accident; monitor that the core electric current will cause monitoring the protector action; in time cut off the electricity supply, so that cable is guaranteed to keep in good repair, if monitor that the core cross section is less; also easily broken core affects the normal operation that monitors core.
The utility model content
Goal of the invention: in order to overcome common coal-winning machine control core, to monitor the defective of the easily broken core of core, the purpose of this utility model is to provide a kind of soft cable of coal mining machine of reasonable in design, long service life.
Technical scheme: in order to solve above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of soft cable of coal mining machine, comprise the cable core that is positioned at the center, and be coated with successively semi-conductive tape, inner sheath, reinforced layer and oversheath in the outside of cable core; Described cable core comprises that power core, control monitor core, wherein said control monitors that core comprises the control core, monitors core and semi-conductive layer, described supervision core twines the outside that is arranged at the control core, and described semi-conductive layer is extruded in the outside of described supervision core.
Wherein, described power core is three and in twos tangent setting, is provided with filling at the center gap place of three power cores; Described control monitors that core also is three, is arranged at respectively between adjacent two power cores.
Wherein, described control core comprises control core strengthening core, tinned copper wire control line core conductor and insulating barrier from the inside to the outside successively, and described supervision core twines the outside that is arranged at described insulating barrier.Described control core strengthening core is by many zinc-coated wires or aramid fiber yarn is stranded forms.
Wherein, described supervision core comprises supervision core strengthening core and tinned copper wire pilot wire core conductor, and described supervision core strengthening core and pilot wire core conductor weave in the same way.
Described pilot wire core conductor has many and be evenly distributed in the described supervision core strengthening core.
Described supervision core strengthening core is formed by many zinc-coated wires or aramid fiber yarn braiding.
Beneficial effect: compared with prior art, the utility model has the advantages that: 1) the utility model will be controlled core and monitor that core is designed to control supervision core and the respectively reinforcement of an integral body, control core and supervision core promote intensity and toughness mutually, thereby can greatly improve anti-bending, stretching, towing performance, the anti-extrusion and resistance to tension of soft cable of coal mining machine, prolong the useful life of cable;
2) control of three integral body of the utility model monitors that core is positioned between three power cores, forms the 3+3 symmetrical structure, and cable core is arranged closely, compact conformation and stablizing;
3) pilot wire core conductor of the present utility model is added by tinned copper conductor and adopts behind zinc-coated wire or the aramid fiber yarn synnema braiding machine to weave in the same way to form, thereby eliminated the contact resistance that the two-way braiding of existing employing brings, monitored that core extrudes semi-conductive layer outward again and guarantees to monitor the core normal operation;
4) interior oversheath of the present utility model all adopts tension, high strength, and anti-bending, the wear-resistance protective sleeve material has further promoted properties and the useful life of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of soft cable of coal mining machine comprises the cable core 1 that is positioned at the center and coats successively semi-conductive tape 2, inner sheath 3, reinforced layer 4 and the oversheath 5 that is arranged at outside the cable core 1.Reinforced layer 4 doubles as ground wire, adopts the braiding of tinned copper wire and zinc-coated wire or tinned copper wire and aramid fiber yarn or winding.Inner sheath 3 and oversheath 5 all adopt tension, high strength, anti-bending, wear-resistance protective sleeve material.
Cable core 1 comprises that the power core 11 of three in twos tangent settings, three controls monitor core and fill 15, and filling 15 is arranged on the center gap place of three power cores 11; Three controls monitor that core is separately positioned between adjacent two power cores 11.
Every control monitors that core includes the control core 12 that sets gradually from inside to outside, monitors core 13 and semi-conductive layer 14, and control core 12 comprises from the inside to the outside successively the stranded control core strengthening core of being made by zinc-coated wire or aramid fiber yarn, adopts tinned copper wire control line core conductor and insulating barrier; Monitor that core 13 comprises the pilot wire core conductor by many zinc-coated wires or the stranded supervision core strengthening core that forms of aramid fiber yarn and Duo Gen employing tinned copper wire, the pilot wire core conductor is evenly distributed on and monitors in the core strengthening core, monitors that core strengthening core and pilot wire core conductor adopt braiding machine to get wherein the spindle of half and weave in the same way and be entwined; Monitor that core 13 twines outside the insulating barrier that is arranged at control core 12.
Owing to will control core 12 and monitoring that the as a whole control of core 13 designs monitors core, control core 12 and supervision core 13 can support each other like this, simultaneously comprise respectively separately strengthening core again, further promoted the tension resistance to bend(ing) energy of control supervision core.
