Technical field
The utility model relates to a kind of cable, particularly relates to a kind of mobile power consumption equipment flexible cable.
Background technology
Cut in this kind of mobile power consumption equipment course of work of goods vertical conveyor in similar high-building construction, cable one end is connected on power consumption equipment and must moves up and down thereupon, its impulse stroke mostly reaches tens of rice, some is even up to more than hundred meters, cable used can be subject to pulling force in motion process, also can be impacted along with the start and stop of power consumption equipment, these pulling forces and impulsive force all need to be born by the core conductor of cable, this causes the power cable commonly used in use due to stressed larger, often cause the disconnected core of cable, the earth connection that particularly wherein wire diameter is relatively little more easily damages, useful life is often all very short.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of engineering lift mobile flexible cable, and it has higher resistance to tension, preferably pliability, long service life.
In order to solve the problems of the technologies described above, a kind of engineering lift mobile flexible cable of the present utility model, comprises core and oversheath, and described core comprises three master cores and a subordinate line core; Each master core described and subordinate line core include strengthening core and core conductor, and this core conductor is the six groups of core conductor bundle that hinge in strengthening core periphery, and it is 1-1/3 that the core cross-sectional area of conductor of subordinate line core amasss the ratio long-pending with the core cross-sectional area of conductor of master core; Each core periphery is coated with insulating barrier, and the outside of four core external insulation layers is coated with inner sheath, and inner sheath is outside equipped with braid, and braid is coated with oversheath.
In said structure, because described core comprises three master cores and a subordinate line core; Each master core described and subordinate line core include strengthening core and core conductor, this core conductor is the six groups of core conductor bundle that hinge in strengthening core periphery, then in master core and subordinate line core, all online core conductor inside is provided with strengthening core, cable suffered pulling force and impulsive force of being subject to along with the start and stop of power consumption equipment in motion process can be born by strengthening core, and do not affect the conducting function of cable, improve whole cable tensile strength, avoid conductor and to break the possibility of core.Core conductor is hinge in that six groups of core conductor bundle of strengthening core periphery then ensure that the softness of cable on the basis that improve cable strength; Again because each core periphery is coated with insulating barrier, the outside of four core external insulation layers is coated with inner sheath, inner sheath is outside equipped with braid, braid is coated with oversheath, then inner sheath and the outer coated insulating barrier of each core are connected as a single entity, and under the acting in conjunction of inner sheath, braid and oversheath, add cable breaking tenacity, insulation resistance to tension and cable alternating bending ability, improve the useful life of cable; And the core cross-sectional area of conductor of subordinate line core to amass the ratio long-pending with the core cross-sectional area of conductor of master core be 1-1/3, then three master cores can meet the power reguirements of power consumption equipment, subordinate line heart yearn core area is less can meet power supply safety requirement as earth connection, makes whole cable cost relatively low.
A kind of preferred implementation of the present utility model, to be that the aviation zinc-coated wire of 0.2mm is stranded by some diameters form described strengthening core.Adopt this execution mode, strengthening core is hinged to form by finer wire, can ensure that it has good pliability.
Another kind of preferred implementation of the present utility model, described core conductor bundle forms by some 0.2mm copper free wires are stranded.Adopt this execution mode, core conductor bundle forms by some thin copper free wires are stranded, can ensure that it has good pliability.
Another preferred implementation of the present utility model, the twisting pitch between six groups of core conductor bundle of described master core and strengthening core is not more than 45mm, and the twisting pitch between six groups of core conductor bundle of described subordinate line core and strengthening core is not more than 35mm.Adopt this execution mode, the twisting pitch between each core conductor bundle and corresponding strengthening core is less, and cable has good bending property, also can make core conductor bundle together with closely hinge between strengthening core simultaneously.
The further preferred implementation of the utility model, described insulating barrier is ethylene propylene diene rubber insulating barrier.Adopt this execution mode, ethylene propylene diene rubber has the advantages that insulation property are high, elongation pliability is good, is conducive to the pliability improving cable.
Another further preferred implementation of the utility model, described inner sheath is chlorinated polyethylene rubber sheath.Adopt this execution mode, can be made together with inner sheath is extruded in each core conductor by the mode extruded, can improve the resistance to tension of cable, and chlorinated polyethylene rubber has good oil resistance, the life-span of cable used in moving process is improved advantageously.
The another further preferred implementation of the utility model, described braid is that high strength twists with the fingers the thin flax silk braid of stock.Adopt this execution mode, the resistance to tension of cable can be improved further.
The utility model is preferred implementation further, and described oversheath is chlorinated polyethylene rubber sheath.Adopt this execution mode, chlorinated polyethylene rubber is fire-retardant, wear-resisting, can be cable and provides well fire-retardant and wear-resistant protection.
