Abstract
The invention discloses an aramid fiber reinforced shielding rubber jacketed flexible cable for a coal mining machine, which comprises a cable core and an inner jacket extruded on the cable core. An aramid fiber knitted reinforcement layer is weaved on the outer surface of the inner jacket; an outer jacket is extruded on the aramid fiber knitted reinforcement layer; and the cable core is formed by twisting a plurality of power wire cores, ground wire cores and control wire cores. The cable is mainly used for power devices of coal mining machines in underground coal mines and has the characteristics of high flexibility, winding property and tensile strength and long service life.
Description
?
Technical field
The present invention relates to the electric wire field, specifically be meant the reinforced coal-winning machine shielding of a kind of aramid fiber rubber sleeve flexible cable.
Background technology
At present; Existing electric cable for coal mining machine reinforcement adopts modes such as wrapped reinforcement, braiding reinforcement usually; Promptly after the cable insulation core is stranded, extrude one deck sheath, adopt twining package tape, nonwoven fabrics, material such as metal knitted to strengthen, and then extrude one deck outer jacket on sheath surface.The following defective of these version ubiquities: though twining package tape, nonwoven fabrics, reinforcement material such as metal knitted have improved the tensile strength and the shielding properties of cable; But because quality is harder; Crooked, coiling performance in cable laying and the use have been influenced simultaneously, especially for the coal-winning machine rubber sleeve flexible cable, in frequent crooked dilatory process; Deflect performance and have a greatly reduced quality, can't guarantee long-term normal use of cable.
Summary of the invention
The technical problem that the present invention will solve provides the reinforced coal-winning machine shielding of a kind of aramid fiber rubber sleeve flexible cable, through adopting flexible reinforcement, makes bendability, coiling property and the tensile property of this cable improve, and has prolonged the useful life of cable.
The reinforced coal-winning machine shielding of aramid fiber of the present invention rubber sleeve flexible cable comprises cable core and is extruded in the outer inner sheath of cable core, at inner sheath outer surface braiding one deck aramid yarn braiding reinforced layer, outside aramid yarn braiding reinforced layer, extrudes oversheath again.
Said cable core be by several power cores, core and control core is stranded forms, wherein, said power core is a wrapped power line core insulation outside the power line core conductor, outside the power line core insulation, weaves power core semiconductive shielding layer and forms; Said ground core then is provided in a side of the ground wire core conductor of cable center or by the ground wire core conductor and be woven in the outer ground core semiconductive shielding layer of ground wire core conductor and form; Said control core is outside the control line core conductor, to extrude control core edge, outside control core edge, extrudes control core coating layer and forms.
Said oversheath is made up of internal layer oversheath and outer oversheath.Aramid yarn braiding reinforced layer is made up of one deck aramid yarn of the multiply aramid fiber yarn that becomes sth. made by twisting to twist together and its surface weave.
Beneficial effect of the present invention:
The present invention is mainly used in colliery silo shearer class pseudodynamic device, has waterproof, anticorrosion, anti-tampering, high flame retardant and tension, anti-function such as pull; The high strength aramid yarn reinforcement material tensile strength that is adopted is high, is easy to later process processing, compares with metal shielding, need not large-scale steel band, steel wire armouring machine, is convenient to workman's operation, has reduced energy consumption.This cable has improved bending, the tensile property of cable, prolongs the useful life of cable, has improved economic benefit.

Fig. 1 is the structure chart of the embodiment of the invention 1.
Fig. 2 is the structure chart of the embodiment of the invention 2.
Fig. 3 is the structure chart of aramid yarn braiding reinforced layer of the present invention.
Embodiment:
Like Fig. 1, shown in 2; The reinforced coal-winning machine shielding of a kind of aramid fiber of the present invention rubber sleeve flexible cable; Comprise cable core and be extruded in the outer inner sheath of cable core,, outside aramid yarn braiding reinforced layer 5, extrude oversheath again at inner sheath 4 outer surfaces braiding one deck aramid yarn braiding reinforced layer 5.Wherein:
Cable core be by several power cores 1, core 2 and control core 3 stranded forming, said power core 1 is a wrapped power line core insulation outside the power line core conductor, outside the power line core insulation, weaves power core semiconductive shielding layer and forms; 2 of said ground cores are by the ground wire core conductor (Fig. 1) of cable center or by the ground wire core conductor and be woven in the outer ground core semiconductive shielding layer of ground wire core conductor and form (Fig. 2); Said control core 3 is outside the control line core conductor, to extrude control core edge, outside control core edge, extrudes control core coating layer and forms.Oversheath is made up of internal layer oversheath 6 and outer oversheath 7.
As shown in Figure 3, aramid yarn braiding reinforced layer is earlier 10 one-tenth sth. made by twisting of multiply aramid fiber yarn to be twisted together, and then at its surface weave one deck aramid yarn 11, forms constitutionally stable aramid yarn braiding reinforced layer.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
