Abstract
The utility model relates to a cable and particularly relates to a construction-ladder rubber-sleeve flexible cable. The construction-ladder rubber-sleeve flexible cable includes a plurality of copper conductors arranged in the cable. Insulating layers are arranged outside the copper conductors. The cable is characterized in that a steel wire rope is embedded among the plurality of copper conductors. A steel-wire-rope insulating layer is arranged outside the steel wire rope. An inner protective sleeve and a braided-fiber reinforcement layer are sleeved in order outside the plurality of copper conductors. The construction-ladder rubber-sleeve flexible cable has the characteristics of being simple in structure, high in cable strength, less susceptible to deformation and long in service life and the like.
Description
Technical field
The utility model relates to a kind of cable, especially relates to the terraced rubber sleeve flexible cable of a kind of construction.
Background technology
As everyone knows, at present, China is the Urbanization Construction that emphasis drops in 12 planning, within a large amount of construction-engineering project in all parts of the country has been included local plan in, and increases sharply with the 450/750V terraced flexible cable consumption thereupon of constructing with constructional engineering machinery is supporting; At present the matched cable of China many construction ladder producer all adopts general rubber sleeve flexible cable, and the very short and security performance of this cable life cycle under this occasion can not get guarantee; Research and develop and the high-performance building engineering that comes into operation is extremely urgent with the terraced cable of construction, the construct application of terraced cable of high end performance is imperative, and this has caused the great attention of domestic many cable enterprise.
The specification requirement of construction elevator private cable and general rubber sleeve flexible cable have a great difference on technique and material.Common general rubber sleeve flexible cable can be distorted distortion, bulge, broken skin until the problems such as heart yearn that fracture use January as elevator cable on lift after, cause cable partially short useful life, busy building hoist upper and lower hundreds of every day is inferior in general, day by day, cable lower end excessive fatigue under the effect of twisting resistance and distortion gradually, so general General Purpose Rubber cable is difficult on building hoist to use for a long time.Yct building hoist private cable that must be professional for this situation, lift private cable mainly meets domestic large-scale lifter apparatus.Along with improving constantly of lift height, requirement to supporting cable is very different, because in lift running, very large stress can be gathered in cable inside, when the height of lift is greater than the lift that 120m[is traditional, be 70m left and right], torsional stress in cable can be larger, traditional Plastic-sheathed Cable is for after this type of lift, core frequently breaks because torsional stress can not eliminate in time or alleviate, in order to meet the normal operation of jacking equipment, extend the useful life of cable, we develop, develop high performance building hoist private cable, can meet the demand of specialty of building hoist industry exactly.
At present domesticly for construction ladder cable, all adopt general rubber sleeve flexible cable to replace, general rubber sleeve flexible cable as elevator cable, uses the distortion that can be distorted after January, bulge, broken skin on lift until the problems such as heart yearn that fracture, and causes cable useful life very short and have a potential safety hazard.General busy building hoist upper and lower hundreds of every day time, day by day, cable lower end excessive fatigue under the effect of twisting resistance and distortion gradually, so general common Plastic-sheathed Cable is difficult to use for a long time on building hoist.Domestic also do not have this type of special product temporarily.
Summary of the invention
The utility model is mainly for the existing above-mentioned technical problem of prior art, provide a kind of simple in structure, cable intensity is high, the construction of not yielding, long service life ladder rubber sleeve flexible cable.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the terraced rubber sleeve flexible cable of a kind of construction, comprise many copper conductors that are arranged on cable inside, copper conductor is outside equipped with insulating barrier, it is characterized in that being embedded with steel wire rope between many described copper conductors, described steel wire rope is outside equipped with steel wire rope insulating barrier, and many described copper conductors are also arranged with inner sheath and braided fiber silk reinforced layer outward successively.Cable conductor adopts the circular annealed copper wire of multiply (the 6th kind of conductor) to be twisted into circle; extruded insulation, at the outer winding of insulation cotton tape protective layer; stranded, the central filler wires rope of cable core adds insulating barrier; does not fill the stranded periphery of cable core; extrude sticking type inner sheath; the peripheral employing of inner sheath added the two-way braiding reinforcement of 50% high strength fibre silk, both played torsional strength and the flexibility that to the friction protection of cable, also can increase cable, and outermost layer extrudes high strength protective cover material.
As preferably, described braided fiber silk reinforced layer is arranged with oversheath outward.Due to cable, use for a long time out of doors the adverse circumstances such as sex climate, protective cover material adopts haloflex rubber compound, and main component has: chlorinated polyethylene rubber, and modified kaolin, half reinforcement is black, antioxidant, ultra-violet absorber etc.; The cable of having avoided of this kind of jacket formula is used the phenomenon of outward appearance cracking out of doors; The existing better physical property of sheath and chemical functional have again good environmental-protecting performance.Make product there is reliable salt fog resistance, oil resistant, fire-retardant, low temperature resistant, warp resistance, resistance to sunlight is exposed to the sun, resistance to outdoor sex climate pollutes and bending resistance.
As preferably, described insulating barrier is arranged with the outer wrapped cotton tape of insulation outward.The utility model structure is science relatively, and technique is advanced, easy to operate, cable long service life.
As preferably, the quantity of many described copper conductors is four.The improvement of the improvement of the utility model structure and insulation protection mode, makes its cable have flexibility, resistance to bend(ing) energy, and cable can make it guarantee that conductor does not rupture, insulating sleeve does not ftracture under long-term rotation bending state.
Therefore, the utlity model has simple in structure, the feature such as cable intensity is high, not yielding, long service life.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
