Abstract
The utility model discloses a bend-resistant flexible cable of a coal mining machine, relating to a cable. The bend-resistant flexible cable comprises a power line, an earth wire and a control line, wherein the power line, the earth wire and the control line are wrapped in an outer sheath; the power line is composed of a power line conductor, a polyester belt wrapped outside the power line conductor, a power line insulating layer wrapped outside the polyester belt, and a shielding layer wrapped outside the power line insulating layer; the control line is composed of a control line conductor, an insulating layer and a control line core protection layer; each phase of the power line conductor is formed by bunching three multi-strand tinned copper wires in an arc-shaped and parallel way; a reinforcing core is arranged in the center of the power line conductor; and the earth wire adopts the tinned copper wires to be woven on the surface of the control line core protection layer. The bend-resistant flexible cable has the advantages as follows: the whole outer diameter of the cable can be reduced, the flexibility bending radius of the cable can be improved to below three times, the deflection performance of the cable can be improved and the service life of the cable can be prolonged.
Description
Technical field
The utility model relates to a kind of cable, specifically 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 6 times of places uses that bending radius is not less than cable size, the crooked flexibility of the soft cable of coal mining machine that the method is produced is poor, easily fractureed, 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 is easily fractureed, the utility model provides a kind of anti-crooked soft cable of coal mining machine, after being subjected to 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 utility model is realized 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 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 of side by side three multiply tin-coated copper tow strands, arcs; 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.
The utility model has the advantages that: power line is by one of original every phase, change into and whenever being formed 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, increase the performance that deflects of cable, improve simultaneously the crooked retractility of cable, thereby guaranteed the normal operation of coal-winning machine.
