Abstract
The utility model discloses an elevator private cable, including the cable core, the cable core includes 4 insulation core, and insulation core restraints the hank by zinc -plated flexible conductor and aramid fiber and forms including combination conductor, combination conductor, and the outside of combination conductor has set gradually around covering, insulating layer and shielding enhancement layer, and 4 insulation core strand into the cable core, and the outside of cable core has set gradually interior sheath, weaving layer and oversheath, and the outside of interior sheath is provided with the arch. The utility model discloses a center of combination conductor adopts aramid fiber as the tension member to set up the one deck and wind the covering outside the conductor, strengthened the concentrated stress and the tensile ability of conductor. When the stranding, sheath in the outer directly crowded package of cable core, the clearance between the sinle silk is closely knit by the packing of sheath material, and with each insulation core rigidity, the cable core sets up the sparse enhancement layer of weaving of aramid fiber outward, directly sticiss crowded package oversheath, makes oversheath, enhancement layer, inner sheath combine together, and during the long -term atress of cable, deformation, swell or sheath fracture phenomenon can not take place for the cable.
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, have also been obtained as the construction elevator of skyscraper vertical transport and be widely applied, due to construction elevator private cable need long-term work in the open, have in the adverse circumstances such as greasy dirt, it is subject to UV sunlight long-term irradiation, and bending repeatedly every day (up to tens meters, rice even up to a hundred) up and down, torsion, under self gravitation effect, subject bigger pulling force and bending。Therefore, cable be easier to fatigue occurs and deform gradually, bulge, the problem such as cracking, even core fracture。At present, 3-5 month it is only the service life of domestic traditional construction cable。
Accordingly, it would be desirable to a kind of new elevator private cable is to solve the problems referred to above。
Summary of the invention
Goal of the invention: the present invention is directed to the defect of elevator cable in prior art, it is provided that a kind of elevator private cable that can effectively extend cable service life。
Technical scheme: for solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of elevator private cable, including cable core, described cable core includes 4 insulated wire cores, described insulated wire cores includes combined conductor, described combined conductor is twisted by tin plating flexible conductor and aramid fiber bundle and forms, described combined conductor be orderly arranged outside each lapping layer, insulating barrier and shielding enhancement Layer, 4 described insulated wire cores are twisted into cable core, described cable core be orderly arranged outside each sheath, braid and oversheath, the arranged outside of described sheath has projection。
Further, described shielding enhancement Layer is aramid fiber yarn strand and the shielding enhancement Layer of tinned copper wire braiding。It is provided with aramid fiber yarn strand and the shielding enhancement Layer of tinned copper wire braiding, not only increases the shielding properties of cable, and improve the tensile strength of cable, reduce the probability of core fracture。
Further, described projection is evenly distributed on described sheath。Projection is evenly distributed on sheath to can ensure that the concordance of the resistance to tension in cable all directions。
Further, on the axis direction of cable, the distance between adjacent described projection is 2-3cm；On the circumferencial direction of cable, the distance between adjacent described projection is 2-3cm。Adopting this spacing, size to fit, the resistance to tension reinforced effects for cable is best。
Beneficial effect: the center of the elevator private cable combined conductor of the present invention adopts aramid fiber as tension member, and arranges one layer of lapping layer outside conductor, enhances concentrated stress and the resistance to tension of conductor。When stranding, sheath is directly extruded outside cable core, gap between core is filled closely knit by sheath material, each insulated wire cores position is fixed, aramid fiber open-weave enhancement Layer is set outside cable core, directly presses and extrude oversheath, make oversheath, enhancement Layer, inner sheath combine together, during the long-term stress of cable, cable will not deform, bulge or sheath cracking phenomena。
Accompanying drawing explanation
Fig. 1 is the structural representation of the elevator private cable of the present invention。
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described。Below it is only the better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is made, and all should include in the protection domain recorded in claims。
Referring to shown in Fig. 1, the elevator private cable of the present invention, including cable core, cable core includes 4 insulated wire cores 1, and insulated wire cores 1 includes combined conductor 2, and combined conductor 2 is twisted by tin plating flexible conductor and aramid fiber bundle and forms。Tin plating flexible conductor adopts the 6th kind of soft tin plating copper free wire flexible conductor of spy, combined conductor 2 be orderly arranged outside each lapping layer 3, insulating barrier 4 and shielding enhancement Layer 5,4 insulated wire cores 1 are twisted into cable core, cable core be orderly arranged outside each sheath 6, braid 7 and oversheath 8。Wherein, the arranged outside of sheath 6 has projection, protruding in the arranged outside of sheath, projection can be significantly increased the contact area between sheath and oversheath, so that the ability that oversheath, fibrage enhancement Layer and sheath combine together is greatly enhanced, greatly strengthen resistance to tension, and can effectively be adjusted the resistance to tension of cable all directions by the size and spacing regulating projection。
Shielding enhancement Layer 5 is aramid fiber yarn strand and the shielding enhancement Layer of tinned copper wire braiding。It is provided with aramid fiber yarn strand and the shielding enhancement Layer of tinned copper wire braiding, not only increases the shielding properties of cable, and improve the tensile strength of cable, reduce the probability of core fracture。
Preferably, projection is evenly distributed on sheath。Projection is evenly distributed on sheath to can ensure that the concordance of the resistance to tension in cable all directions。On the axis direction of cable, the distance between adjacent protrusion is 2-3cm；On the circumferencial direction of cable, the distance between adjacent protrusion is 2-3cm。Adopting this spacing, size to fit, the resistance to tension reinforced effects for cable is best。
The center of the elevator private cable combined conductor of the present invention adopts aramid fiber as tension member, and arranges one layer of lapping layer outside conductor, enhances concentrated stress and the resistance to tension of conductor。When stranding, sheath is directly extruded outside cable core, gap between core is filled closely knit by sheath material, each insulated wire cores position is fixed, aramid fiber open-weave enhancement Layer is set outside cable core, directly presses and extrude oversheath, make oversheath, enhancement Layer, inner sheath combine together, during the long-term stress of cable, cable will not deform, bulge or sheath cracking phenomena。
