Abstract
The invention discloses a cable special for an elevator. The cable comprises a cable core, wherein the cable core comprises four insulation wire cores, each insulation wire core comprises a combined conductor, the combined conductor is formed by bunch stranding of a tin plated soft conductor and aramid fiber, a wrapping layer, an insulation layer and a shielding reinforcement layer are sequentially arranged outside the combined conductor, the four insulation wire cores are stranded to form the cable core, and an inner protection layer, a weaving layer and an outer sheath are sequentially arranged outside the cable core. The center of the combined conductor of the cable special for the elevator adopts the aramid fiber as a tensile member, the wrapping layer is arranged outside the conductor, and thus, the concentrated stress and the tensile capability of the conductor are improved; and during cabling, the inner protection layer is directly extruded outside the cable core, a gap among the wire cores is densely filled with a sheath material to make the position of each insulation wire core fixed, an aramid fiber sparsely-weaving reinforcement layer is arranged outside the cable core to directly and tightly extrude the outer sheath, so that the outer sheath, the reinforcement layer and the inner sheath are integrated, and the phenomena of cable deformation, bulging or sheath cracking can be prevented when the cable bears stress for a long time.
Description
Technical field
The invention belongs to field of cables, relate to a kind of elevator private cable.
Background technology
Along with the speed of Modernized City Construction is accelerated, the construction of skyscraper increases year by year, construction elevator as skyscraper vertical transport have also been obtained to be applied widely, due to construction elevator private cable need long-term work in the open, have in the adverse circumstances such as greasy dirt, be subject to UV sunlight long-term irradiation, and the every day of (up to tens meters, rice even up to a hundred) bending, torsion repeatedly up and down, under self gravitation effect, subject larger pulling force and bend.Therefore, cable more easily occur overtired and be out of shape gradually, bulge, the problem such as cracking, even core fracture.At present, 3-5 month is only the useful life of domestic traditional construction cable.
Therefore, need a kind of new elevator private cable to solve the problem.
Summary of the invention
Goal of the invention: the defect that the present invention is directed to elevator cable in prior art, provides a kind of elevator private cable that effectively can extend cable useful life.
Technical scheme: for solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of elevator private cable, comprise cable core, described cable core comprises 4 eradication edge fibre cores, described insulated wire cores comprises combined conductor, described combined conductor is twisted by zinc-plated flexible conductor and aramid fiber bundle and forms, the outside of described combined conductor is disposed with lapping layer, insulating barrier and shielding reinforced layer, and 4 described insulated wire cores are twisted into cable core, and the outside of described cable core is disposed with sheath, braid and oversheath.
Further, described shielding reinforced layer is the shielding reinforced layer of aramid fiber yarn strand and tinned copper wire braiding.Be provided with the shielding reinforced layer of aramid fiber yarn strand and tinned copper wire braiding, not only increase the shielding properties of cable, and improve the tensile strength of cable, reduce the possibility of core fracture.
Beneficial effect: the center of elevator private cable combined conductor of the present invention adopts aramid fiber as tension member, and arranges one deck lapping layer outside conductor, enhances concentrated stress and the resistance to tension of conductor.When stranding, cable core directly extrudes sheath outward, gap between core is filled closely knit by sheath material, each insulated wire cores position is fixed, aramid fiber open-weave reinforced layer is set outside cable core, directly presses and extrude oversheath, oversheath, reinforced layer, inner sheath are combined together, cable long-term stressed time, cable can not deform, bulge or sheath cracking phenomena.
Accompanying drawing explanation
Fig. 1 is the structural representation of elevator private cable of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.Below be only better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned execution mode; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is done, and all should include in the protection range recorded in claims.
Refer to shown in Fig. 1, elevator private cable of the present invention, comprises cable core, and cable core comprises 4 eradication edge fibre cores 1, and insulated wire cores 1 comprises combined conductor 2, and combined conductor 2 is twisted by zinc-plated flexible conductor and aramid fiber bundle and forms.Zinc-plated flexible conductor adopts the 6th kind of soft zinc-plated copper free wire flexible conductor of spy,
The outside of combined conductor 2 is disposed with lapping layer 3, insulating barrier 4 and shielding reinforced layer 5,4 insulated wire cores 1 and is twisted into cable core, and the outside of cable core is disposed with sheath 6, braid 7 and oversheath 8.
Shielding reinforced layer 5 is the shielding reinforced layer of aramid fiber yarn strand and tinned copper wire braiding.Be provided with the shielding reinforced layer of aramid fiber yarn strand and tinned copper wire braiding, not only increase the shielding properties of cable, and improve the tensile strength of cable, reduce the possibility of core fracture.
The center of elevator private cable combined conductor of the present invention adopts aramid fiber as tension member, and outside conductor, arrange one deck lapping layer, enhances concentrated stress and the resistance to tension of conductor.When stranding, cable core directly extrudes sheath outward, gap between core is filled closely knit by sheath material, each insulated wire cores position is fixed, aramid fiber open-weave reinforced layer is set outside cable core, directly presses and extrude oversheath, oversheath, reinforced layer, inner sheath are combined together, cable long-term stressed time, cable can not deform, bulge or sheath cracking phenomena.
