Description
Technical field:
The utility model relates to drum cable, relates in particular to a kind of light-duty reel rubber control flexible cable.
Background technology:
Drum cable all is to use on mechanically moving, and be contained in the circular cylinder body, in use, cable is ceaselessly rolled and is emitted with certain acceleration in cylindrical shell, it also will bear certain pulling force and twisting resistance when mobile rolling and emit, common cable or drum cable can't bear this kind condition of work, tend to cause conductor break, cause cable conductor to open circuit or scrap, because the conductor of cable all is to adopt that soft copper wire is stranded to be formed, the elongation at break of its thin copper wire all is about 25%, percentage elongation is less, and in conductor when elongation, can't resilience, can't with elongation at break be 400% or more have flexible insulation and sheath is compared, so it can rupture with certain acceleration coiling folding and unfolding bending the time, add round cable and when the coiling folding and unfolding, can produce axial torsion, this axial torsion also can cause the destruction of cable conductor, and common drum cable can't adapt under the severe environmental conditions and uses, and its useful life is also very short.
Even some drum cable adds steel wire in conductor, but the adding of steel wire tends to increase the weight of the weight of cable, increases extra burden for the reel hold cable, and very inconvenient during the coiling folding and unfolding.In addition, cable core was easily impaired when drum cable was squeezed, and caused the information transmission not smooth, brought huge loss.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of light-duty reel rubber control flexible cable, be applicable in the lifting device system of the vertical operations such as harbour or other rotary machine, portal jib crane, Transport Machinery, large-scale tower crane, open-air lift for building, reasonable in design has slim and graceful, oil resistant, corrosion-resistant, cold-resistant, tension, anti-torsion, wear-resisting, the soft characteristic of being convenient to movement of high flame retardant.
The technical solution of the utility model is as follows:
Light-duty reel rubber control flexible cable, comprise several conductors, it is characterized in that: described several conductors adopt the soft copper wire of zinc-plated oxygen-free copper stranded bunchy centered by strengthening core to consist of, strengthening core adopts aramid yarn and carbon fibre tow strand to consist of, described several conductor is coated with respectively interior aramid fiber yarn braid outward successively, ethylene propylene rubber insulated layer consists of insulated wire cores, the mutual stranded bunchy of insulated wire cores consists of cable core, cable core is coated with inner restrictive coating outward successively, outer aramid fiber yarn braid, resilient coating, resilient coating adopts the foamed plastic extrusion moulding to consist of, and the outer extrusion moulding of resilient coating has neoprene mixed rubber restrictive coating.
Described light-duty reel rubber control flexible cable, it is characterized in that: described interior aramid fiber yarn braid count is not less than 85%, the count of outer aramid fiber yarn braid is not less than 96%, the elongation at break 2% ~ 6% of interior aramid fiber yarn braid and outer aramid fiber yarn braid.
The utility model has the advantages that:
1, the utility model cable conductor adopts the soft body conductor of the zinc-plated oxygen-free copper of anti-oxidant high elongation rate, and the percentage elongation of conductor is more than 30%, and the conductor of high elongation rate can bear larger bent without breaking.
The utility model adopts aramid yarn and carbon fiber wire as reinforcement in the middle of conductor; conductive surface braiding aramid yarn is as the conductor reinforced layer; because aramid fiber yarn has superhigh intensity; lightweight; the characteristic that elongation at break is little; its intensity is 5～6 times of steel wire; and weight only is about 1/5th of steel wire; elongation at break only has about 4%; because the percentage elongation of aramid yarn is less than the copper wire; intensity is high; the intensity of copper wire and aramid yarn and percentage elongation differ larger; the cable aramid yarn that in the conductor and conductor outside weaves when bending has afforded crooked pulling force; but conductor does not also afford pulling force and beaming limit; greatly protected cable conductor; reinforcement adopts aramid yarn and carbon fiber wire; its weight only is about 1/5th of steel wire, and its weight of proportion of comparing steel wire also is very light, the lightweight further flexibility of cable when the coiling folding and unfolding that increased.
3, insulating barrier adopts high strength, high elongation rate is ethylene propylene rubber insulated, the tensile strength of second third is at 10MPa, percentage elongation is more than 400%, high elongation rate and to have a percentage elongation of the relative aramid yarn of elastic insulation and copper conductor larger, can strengthen the bending coiling performance of cable, and insulated wire cores must be closely when stranding, the situation that degree of tightness differs must not appear in insulated wire cores, the phenomenon that differs if there is degree of tightness, the phenomenon of unbalance stress will appear in cable when flexural loading, unbalance stress just is easy to cause the fracture of cable conductor core, the tight uniformity of stranding, stressed will uniformity, cable conductor when the coiling folding and unfolding is crooked just is not easy fracture.
4, neoprene inner sheath surface weave aramid yarn is as antitorque reinforced layer---outer aramid fiber yarn braid, because round cable is when the coiling folding and unfolding, can produce axial torsion power, conductor and insulated wire cores all are that certain directivity is arranged when stranded, axially torsion can make conductor and insulated wire cores certain direction reverse tighter or loose, if tightlier surpassing when understanding its limit of axial torsion, conductor thread core can be twisted off.Can cause the conductor insulation core loose if back-out, cause the insulated wire cores unbalance stress, weave aramid yarn as antitorque reinforced layer in the inner sheath outside, can prevent the cable axial torsion, the intensity that aramid yarn is higher and less percentage elongation, cable is when bending, when the aramid yarn of inner sheath surface weave affords crooked pulling force, conductor does not also afford pulling force and beaming limit, and its bending force is all born by aramid yarn, has greatly strengthened the bending property of cable.
5, outer aramid fiber yarn braid is provided with the foamed plastic layer outward, can effectively resist the damage that extraneous extruding force causes cable core, guarantees the stability that cable signal transmits.
6, sheath adopts oil resistant, cold-resistant, wear-resisting, high strength, high flame retardant, anti-tear, corrosion-resistant, the weather neoprene mixed rubber of height, neoprene belongs to self-complementary epistasis rubber, its physical and mechanical property is very good, add in this neoprene epoxy glue and do not add liquid plasticizer, its intensity, oil resistance and tear resistance are better, the rubber of high strength and high tear resistance can be given the higher pull resistance of cable and resistance to wear, strengthened the coiling folding and unfolding performance of cable, add the percentage elongation of neoprene mixed rubber more than 400%, strengthened the bending property of cable.And contain the chlorine element in the neoprene, in this glue, add efficient compound HZR-2 fire retardant, can make the oxygen index of neoprene epoxy glue bring up to 42%, high oxygen index can further improve the anti-flammability of cable, can reach the A level fire-retardant, and sheath cold resistance is high, and the environment for use of cable has been expanded in the folding and unfolding work of can repeatedly reeling in-40 ℃ of environment greatly.
