Description

The soft resistance to trailing cable of environment-friendly and energy-efficient
Technical field:
The utility model relates to a kind of environment-friendly cable, particularly relates to the soft resistance to trailing cable of a kind of environment-friendly and energy-efficient, belongs to special cable technical field.
Background technology:
The toxicity that the cable of Halogen discharges in fire is very fearful, if gas concentration that can causing death at 30 minutes is judged to be to 1, the poison exponent of polyvinyl chloride is 15.01 so, and the poison exponent of ep-type material is 0.79.People can only be survived 2 minutes in the smog of polyvinyl chloride, and changes environment-friendly materials into, and people is survived and just can be extended to 40 minutes in smog, escape time while greatly having improved fire.And developed country developed environment-friendly cable the eighties in eighties of last century, and this nuisanceless cable of recommendation energetically, to replace and progressively discardedly to use poisonous PVC cable.
In the electrical source of power or Data Control circuit of frequent mobile plant equipment, towing along with continuous type frequently reciprocating, cable while laying use is the state in the motion that dynamically circumnutates always, and the destruction of external environment and artificial mechanical external force, cable is generally in free state in towing, and the conductor of cable is bearing main mobile tractive effort.In moving process, Cable Bending Radius is only several times of self external diameter.After thousands of reciprocating motions, under the state of high speed, high frequency, often there is surrender fatigue, produce disconnected core phenomenon in common flexible cable copper stranded conductor conductor, the useful life that only has one or two month, when frequently reversing and moving, easily produce cracking phenomena and cause cable bad, due to the damage of cable, cause the pause of whole work and disorderly problem frequently to occur.Therefore to moving, pliability and the fail safe of cable have proposed higher requirement frequently.
Utility model content:
Technical problem to be solved in the utility model is: provide a kind of environment-friendly and energy-efficient soft resistance to trailing cable, by the structure of cable and protective layer are improved, and add kevlar fiber in conductor inside, greatly strengthened the resistance to fracture property of conductor, flexibility and the pliability of cable have been strengthened, improved the intensity of cable when frequently bearing torsion and bending, extended the useful life of cable, can be applied to frequent torsion, the stronger occasion of crooked and extraneous mechanical damage, can be applied to harbour plant, electric hoist, in the mechanically moving equipment such as coal-winning machine.
The utility model is that the technical scheme that technical solution problem is taked is:
The soft resistance to trailing cable of environment-friendly and energy-efficient, consists of a plurality of insulated wire cores and protection skin, and described protection skin surrounds a plurality of insulated wire cores outside, between insulated wire cores and protection skin, is provided with cable core reinforcement; Each insulated wire cores has included conductor, conductor belting layer and insulating barrier, and described conductor is added with stranded the forming of strand of kevlar fiber by multiply; Described protection skin comprises stranding belting layer, steel wire braid and external sheath layer from inside to outside.
Described insulated wire cores is two or more.
Described insulating barrier adopt high resiliency, high strength, high resilience exempt from vulcanize TPE elastomer and extrude and form.
Described cable core reinforcement is the thin tawny daylily rope made of hemp or high strength synthetic.
Described stranding belting layer selects that polyester belt is wrapped to be formed.
Described steel wire braid is formed by the braiding of multiply finer wire, plays shielding protection effect.
Described external sheath layer adopts high-strength abrasion-proof oil-resisting type to exempt to vulcanize TPU elastomer sheath material and extrudes and form.
Positive beneficial effect of the present utility model is as follows:
1, conductor structure of the present utility model is that many thin copper wires adopt first to restraint and twist afterwards technique, and it is consistent with strand direction of lay to twist again direction, during synnema, add kevlar fiber, the conductor flexibility that this technique is made and rounding are stable, in synnema, add kevlar fiber can greatly improve the tensile strength of conductor, normal conductor just there will be disconnected core phenomenon for several thousand times when waving experiment, the conductor that adds kevlar fiber when waving experiment, under same test conditions, wave number of times and be normal conductor tens times.
2, insulating barrier of the present utility model adopt high resiliency, high strength, high resilience exempt from vulcanize TPE elastomer and extrude and form, TPE has high resiliency, the high strength of vulcanized rubber, high resilience, weatherability, fatigue resistance, environmental protection and temperature tolerance, and there is the performance of technical process of thermoplastics.Owing to not needing through heat cure, use general device of plastic processing can complete production.This feature makes rubber industry production procedure shorten 1/4, and energy efficient 25~40% is raised the efficiency 10~20 times, can be rated as rubber industry material and technology revolution again.
3, external sheath layer of the present utility model adopts high-strength abrasion-proof oil-resisting type to exempt to vulcanize TPU elastomer sheath material to extrude and form equally, and sheath material adopts and meets ROHS instruction-polyurethanes TPU, its resistance to wear, tear resistance, bends that to disturb intensity be all good; Hot strength is high, and percentage elongation is large, the remarkable advantage that the long-term low grade of compression set rate is all TPU, and it also has oil resistant anti-hydrolytic performance simultaneously, and its ambient operating temperature can long-time running between-40 ℃~+ 80 ℃.
4, braiding protective layer of the present utility model adopts multiply finer wire net weaving; respectively after cable core stranding; coated one deck multiply finer wire net braid; further strengthened the tensile strength of whole cable; especially in overlength cable and roving situation, resist the damage of external force to cable, also can eliminate the destruction of external carbuncle to cable simultaneously.
5, the design of cable core reinforcement of the present utility model: for preventing that force localization that cable bears is in conductor thread core, according to the difference of the acceleration of cable moving and the frequency, select the thin tawny daylily rope made of hemp or the high strength that tensile strength is large and toughness is strong to synthesize elasticity thing as cable core reinforcement, can alleviate the infringement of mechanical stress to drag chain cable, also can be as filling, increase the rounding property of cable.
6, the design of the utility model combining structure: adopt reinforcement, cable conductor to add kevlar fiber, the outer comprehensive Design that adopts finer wire braiding protection by conductive cable cores; make cable can bear higher translational acceleration and bear normal temperature, low temperature torsion; the occasion that cable is used is increased, and performance reliability, fail safe that cable is used increase substantially.By cable, being subject to most of stress that the motion such as stretching, extruding, torsion produces all can be by the conversion that composite protection layer absorbs between sheath, reinforcement and insulation, thereby the performance of cable is increased substantially.
