Abstract
The invention discloses an anti-bending flexible cable of a shearer and relates to a cable. The flexible cable comprises power wires wrapped inside an external protective sleeve, a grounding wire and control wires, wherein the power wires are formed by power wire conductors, polyester bands wrapped outside the power wire conductors, power wire insulation layers wrapped outside the polyester bands and shielding layers wrapped outside the power wire insulation layers; the control wires are formed by control wires conductors, insulation layers and control wire core protective layers; each phase of the power wire conductors is formed by three multistrand tinned copper wires which are twisted in parallel to be arc-shaped; reinforced cores are arranged at the centers of the power wire conductors; and the grounding wire adopts a tinned copper wire and is knitted on the surface of the control wire core protective layer. The invention has advantages that the overall external diameter of the flexible cable is reduced, the bending radius of flexibility of the cable is improved by less than three times, flexibility performance of the cable is enhanced, and service life of the cable is prolonged.
Description
Technical field
The present invention relates to a kind of cable, specifically is a kind of anti-crooked soft cable of coal mining machine.
Background technology
Known electric cable for coal mining machine comprise restrictive coating, power line conductor be three-core structure and be cylindrical shape, core and control core; Can only be applicable to that bending radius is not less than 6 times of places uses of cable size; The crooked flexibility of the soft cable of coal mining machine that this method is produced is poor; Easy quilt fractures, and can not adapt to low coal seam coal-winning machine and mine.
Summary of the invention
Poor in order to overcome the crooked flexibility of existing soft cable of coal mining machine, the defective that easy quilt fractures, the present invention provides a kind of anti-crooked soft cable of coal mining machine; After receiving mechanical bend; The bending radius of this cable reaches below 3 times of cable size, has flexibility, is adapted to low coal seam coal-winning machine and mines.
The present invention realizes with following technical scheme: a kind of anti-crooked soft cable of coal mining machine comprises the power line, ground wire and the control line that are wrapped in the oversheath; Described power line is wrapped in the outer polyester belt of power line conductor, is wrapped in the outer power line insulating barrier of polyester belt and is wrapped in the outer screen formation of power line insulating barrier by the power line conductor; Described control line is made up of control line conductor and insulating barrier and control core sheath; It is characterized in that: described power line conductor is every to be made up of three multiply tin-coated copper tow strands, arcs side by side; Center at the power line conductor is provided with strengthening core; Ground wire adopts tinned copper wire to be woven in control core sheath surface.
Advantage of the present invention is: power line is by one of original every phase; Change into and whenever forming side by side by three multiply tin-coated copper tow strand, arcs; The multiply synthetic fibers are put in every conductor center; This structure have conductor diameter little, reduced the outside diameter of cable, the little advantage of bending radius, had flexibility, the flexibility bending radius that the anti-crooked soft cable of coal mining machine that adopts this method to produce can improve whole cable can reach below 3 times, increases the performance that deflects of cable; Improve the crooked retractility of cable simultaneously, thereby guaranteed the normal operation of coal-winning machine.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Among the figure: 1, oversheath, 2, screen, 3, the power line insulating barrier, 4, polyester belt, 5, the power line conductor, 6, strengthening core, 7, ground wire, 8, control core sheath, 9, insulating barrier, 10, the control line conductor.
Embodiment
As shown in Figure 1, a kind of anti-crooked soft cable of coal mining machine comprises power line, ground wire 7 and the control line that is wrapped in the oversheath 1; Described power line is by power line conductor 5, is wrapped in the outer polyester belt 4 of power line conductor 5, is wrapped in the outer power line insulating barrier 3 of polyester belt 4 and is wrapped in power line insulating barrier 3 outer screens 2 and constitute.Control line is made up of with control core sheath 8 control line conductor 10 and insulating barrier 9.Described power line conductor 5 is every to be made up of three multiply tin-coated copper tow strands, arcs side by side; Be provided with strengthening core 6 at the center of power line conductor 5; Ground wire 7 adopts tinned copper wire to be woven in control core sheath surface.
In the present embodiment, oversheath 1 is that haloflex material fire-retardant to have, warping strength, heat-resisting, chemical resistance corrosion extrudes and forms.Screen 2 is semiconductive or metal screen layer, and the employing semi-conductive adhesive is wrapped or metal knitted, shield pack overlays on power line insulating barrier 3 surfaces.Power line insulating barrier 3 extrudes and forms by having excellent electrical, low temperature resistant, anti-ozone, ethylene-propylene diene copolymer heat-resisting, ageing-resistant performance.Strengthening core 6 adopts the multiply fiber to place power line conductor center.Control line conductor 10 adopts the tin-coated copper tow to kink around structure; Control line conductor 10 constitutes the control core with insulating barrier 9, and four control core strandings place the cable center position; Guarantee the flexibility of whole cable, reached Cable Bending Radius below 3 times.
Cable core comprises three-phase power line, four control lines and ground wire, and each core is coated in the oversheath.Four control line conductors are outer through extruding ethylene-propylene diene copolymer formation insulating barrier 9.Four control cores are a unit, and the periphery of this unit constitutes control core sheath 8 through extruding ethylene-propylene diene copolymer.
The power line conductor is every forms a phase power line conductor side by side by three multiply tin-coated copper tow strands, arcs, like former 95mm
2Conductor diameter 14.3mm, every conductor diameter 8.4mm after the method is divided conductor diameter 14.3mm equally three, conductor diameter has reduced 1/3, and bending radius reduces 1/2 than former cable.According to the arrangement mode of power line conductor 5, be wrapped in power line conductor 5 outer polyester belts 4 and be shaped as arc.
