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 a kind of resist bending soft cable of coal mining machine.
Background technology
Known electric cable for coal mining machine comprises restrictive coating, power line conductor is three-core structure and in cylindrical shape, wire core and control conductor, 6 times of places uses that bending radius is not less than cable size can only be applicable to, the soft cable of coal mining machine that the method is produced bends flexibility difference, easily fractureed, low coal seam coal-winning machine can not be adapted to and mine.
Summary of the invention
Bending flexibility difference to overcome existing soft cable of coal mining machine, easily by the defect fractureed, the invention provides a kind of resist bending soft cable of coal mining machine, after being subject to mechanical bend, the bending radius of this cable reaches less than 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 resist bending soft cable of coal mining machine, comprises the power line be wrapped in oversheath, ground wire and control line; Described power line, by power line conductor, is wrapped in the polyester belt outside power line conductor, is wrapped in the power line insulating barrier outside polyester belt and is wrapped in the screen formation outside power line insulating barrier; Described control line is made up of control line conductor and insulating barrier and control conductor sheath; It is characterized in that: described power line conductor is often twisted by three multiply tin-coated copper tow, arc forms side by side; Strengthening core is provided with at the center of power line conductor; Ground wire adopts tinned copper wire to be woven in control conductor sheath surface; Control line conductor adopts tin-coated copper tow to kink around structure; Control line conductor and insulating barrier form control conductor, and four control conductor strandings, are placed in cable center position.
Advantage of the present invention is: power line is by original every phase one, change into and being often made up of side by side three multiply tin-coated copper tow strands, arcs, multiply synthetic fibers are put in every root conductor center, this structure have conductor diameter little, reduce the outside diameter of cable, the little advantage of bending radius, have flexibility, the flexibility bending radius that the resist bending soft cable of coal mining machine adopting this method to produce can improve whole cable can reach less than 3 times, what increase cable deflects performance, improve the bending retractility of cable simultaneously, thus ensure that the normal operation of coal-winning machine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, oversheath, 2, screen, 3, power line insulating barrier, 4, polyester belt, 5, power line conductor, 6, strengthening core, 7, ground wire, 8, control conductor sheath, 9, insulating barrier, 10, control line conductor.
Embodiment
As shown in Figure 1, a kind of resist bending soft cable of coal mining machine comprises the power line be wrapped in oversheath 1, ground wire 7 and control line; Described power line, by power line conductor 5, is wrapped in the polyester belt 4 outside power line conductor 5, is wrapped in the power line insulating barrier 3 outside polyester belt 4 and the screen 2 be wrapped in outside power line insulating barrier 3 is formed.Control line is made up of control line conductor 10 and insulating barrier 9 and control conductor sheath 8.Described power line conductor 5 is often twisted by three multiply tin-coated copper tow, arc forms side by side; Strengthening core 6 is provided with at the center of power line conductor 5; Ground wire 7 adopts tinned copper wire to be woven in control conductor sheath surface.
In the present embodiment, oversheath 1 has haloflex material that is fire-retardant, warping strength, heat-resisting, chemical resistance corrosion to extrude and form.Screen 2 is semiconductive or metal screen layer, and employing semi-conductive adhesive is wrapped or metal knitted, shielding is coated on power line insulating barrier 3 surface.Power line insulating barrier 3 by having excellent electrical, low temperature resistant, resistance to ozone, ethylene-propylene diene copolymer that is heat-resisting, ageing-resistant performance extrude and form.Strengthening core 6 adopts multiply fiber to be placed in power line conductor center.Control line conductor 10 adopts tin-coated copper tow to kink around structure; Control line conductor 10 and insulating barrier 9 form control conductor, and four control conductor strandings, are placed in cable center position; Ensure that the flexibility of whole cable, reach Cable Bending Radius less than 3 times.
Cable core comprises three-phase power line, four control lines and ground wire, and each core is coated in oversheath.Four control line conductors form insulating barrier 9 by extruding ethylene-propylene diene copolymer outward.Four control conductor are a unit, and the periphery of this unit forms control conductor sheath 8 by extruding ethylene-propylene diene copolymer.
Power line conductor is often twisted by three multiply tin-coated copper tow, arc forms a phase power line conductor, side by side as former 95mm
2conductor diameter 14.3mm, every root conductor diameter 8.4mm after the method divides conductor diameter 14.3mm equally three, conductor diameter reduces 1/3, and bending radius reduces 1/2 than former cable.According to the arrangement mode of power line conductor 5, polyester belt 4 shape be wrapped in outside power line conductor 5 is arc.
