Abstract

The utility model discloses a rubber sleeve circular flexible cable capable of traction, which comprises a plurality of soft copper conductors and a kevlar wire core; the kevlar wire core is coated with an extruded outer layer; the outside of the kevlar wire core is encircled evenly with a soft copper conductor; the soft copper conductor is coated with an isolation layer, and the isolation layer is coated with an insulation layer; the insulation layer of the soft copper conductor is coated with an inner sheath; and the inner sheath is coated with a polyamide yarns braided layer, and the polyamide yarns braided layer is coated with an outer sheath. The rubber sleeve circular flexible cable is applicable to the large movable cranes for coal mining and port machinery movable devices, and makes up the defect that the ordinary rubber sleeve flexible cable is not capable of traction. The rubber sleeve circular flexible cable capable of traction has the advantages of large tensile strength, good flexibility, excellent electrical insulation, excellent weather proof performance and physical mechanical performance, high temperature resistant level and the like.

Description

But the double as traction circular flexible cable of rubber sleeve

Technical field:

The utility model relates generally to a kind of cable, but specifically is a kind of circular flexible cable of rubber sleeve of double as traction usefulness.

Background technology:

After the China joined WTO, China's economy is advanced by leaps and bounds, and this just needs by exploitation colliery equal energy source for rapid economic development.In the collecting work process in colliery, because equipment itself need be mobile, so but in the colliery, need to use in a large number double as to draw the Plastic-sheathed Cable of usefulness.As the cable that mining coal-winning machine uses, to draw mobilely in use, if there is not strengthening core, cable is in long-term the use, and is impaired easily through pulling force, reduces the useful life of cable.The cable that mining coal-winning machine uses, because equipment itself needs to move in the course of work, cable also must move by the equipment of following, and requires cable not only to want soft gentle, more certain pulling force will be arranged.Therefore, but the Plastic-sheathed Cable of double as traction usefulness also becomes the particular customer inevitable choice.And national standard or industry standard to this type of cable all less than regulation, use cable also not possess the double as traction function on the market.

The utility model content:

The utility model purpose is exactly in order to remedy the defective of prior art, but provides a kind of double as traction with the circular flexible cable of rubber sleeve, and it has the characteristics such as weather resistance that tensile strength is strong, flexibility is superior, temperature resistant grade is high, high.

The utility model is achieved through the following technical solutions:

But the double as traction includes several soft copper conductors with the circular flexible cable of rubber sleeve, it is characterized in that having aramid fiber silk thread core, and aramid fiber silk thread core extrudes skin outward; Described aramid fiber silk thread core is outer, and described soft copper conductor has separator outward around uniform soft copper conductor, and separator has insulating barrier outward; The insulating barrier of described soft copper conductor has inner sheath outward, and inner sheath has the Polyamide Yarns braid outward, and the Polyamide Yarns braid has oversheath outward.

But described double as traction is characterized in that with the circular flexible cable of rubber sleeve described inner sheath material adopts natural rubber elastomer, and jacket material adopts neoprene; Insulating layer material is an ethylene propylene diene rubber, can make the long-term applied temps of the utility model be increased to 90 ℃ from 65 ℃ of common cable, has increased ampacity greatly, has increased efficient.

Described aramid fiber silk thread core extrudes skin outward, guarantees that cable has double as draw and soft bending property.

Described oversheath adopts chloroprene rubber material, guarantees that it has excellent physical and mechanical performance and good weather resistance.

Described conductor adopts five class standard conductor structures, takes to restraint the mode of strand on the technology, and the pitch multiple is controlled at below 14 times, and cable has excellent bending property like this.

The utility model has taked the Polyamide Yarns braid to improve its tensile strength greatly.

The utility model has the advantages that:

The utility model is a kind of large-scale traveling hoist and harbour machinery mobile device such as coal mining of being applicable to, having remedied common rubber sleeve flexible cable can not be as the defective of traction usefulness.The utlity model has that tensile strength is big, flexibility good, electric insulation is excellent, weather resistance is excellent, physical and mechanical properties is good and the temperature resistant grade advantages of higher.

Accompanying drawing is cross section structure figure of the present utility model.

Embodiment:

But the double as traction includes several soft copper conductors 1, aramid fiber silk thread core 4 with the circular flexible cable of rubber sleeve, the aramid fiber silk thread core 4 outer skins 5 that extrude; Around uniform soft copper conductor 1, outside the described soft copper conductor 1 separator 2 is arranged outside the described aramid fiber silk thread core 4, insulating barrier 3 is arranged outside the separator 2; Outside the insulating barrier 3 of described soft copper conductor 1 inner sheath 6 is arranged, Polyamide Yarns braid 7 is arranged outside the inner sheath 6, oversheath 8 is arranged outside the Polyamide Yarns braid 7.Inner sheath 6 materials adopt natural rubber elastomer, and oversheath 8 materials adopt neoprene, and insulating barrier 3 materials are ethylene propylene diene rubber.

Claims

But the traction of 1 double as includes several soft copper conductors with the circular flexible cable of rubber sleeve, it is characterized in that having aramid fiber silk thread core, and aramid fiber silk thread core extrudes skin outward; Described aramid fiber silk thread core is outer, and described soft copper conductor has separator outward around uniform soft copper conductor, and separator has insulating barrier outward; The insulating barrier of described soft copper conductor has inner sheath outward, and inner sheath has the Polyamide Yarns braid outward, and the Polyamide Yarns braid has oversheath outward.
2, but double as traction according to claim 1 is characterized in that with the circular flexible cable of rubber sleeve described inner sheath material adopts natural rubber elastomer, and jacket material adopts neoprene, and insulating layer material is an ethylene propylene diene rubber.
