Abstract
The utility model discloses a cable for mining conveyance machinery, which comprises a plurality of conductor groups and inner reinforcing layers. The plurality of conductor groups are longitudinally arranged abreast of each other. The plurality of conductor groups are respectively formed by twisting a plurality of identical conductors into a bunch, and the plurality of conductors are respectively coated by an inner reinforcing layer. The plurality of conductor groups are coated by an insulation layer. The insulation layer of the plurality of conductor groups is coated in sequence by an inner sheath layer, an outer reinforcing layer and an outer sheath layer. The inner layer of each conductor adopts a strand wire formed by twisting a plurality of unanealed copper-clad steel wires, tin-coated stranded wires are twisted on the outer layer of the strand wire, the inner reinforcing layer is formed by wrapping high-strength nylon bands, and the outer reinforcing layer is formed by weaving aramid fibers. The cable adopts double-layer reinforcing layers, one layer is arranged on the outside of the conductors, and the other layer is arranged between the inner sheath and the outer sheath. The problem that a conductive wire core of the cable breaks and an overall anti-pulling property is poor is effectively resolved, service life of the cable is prolonged, and good elasticity and bendability are preserved.
Description
Technical field:
This practicality relates to the mine field of cables, relates in particular to a kind of mining conveying machinery cable.
Background technology:
It is to be used for mine scraper or the supporting power consumption cable of similar devices that the rubber insulation mining is carried with mechanical cable, needs frequent moving during use, so to crooked, wear-resisting, punching press with reverse, especially tensile property is had higher requirement.
Because the mining conveying machinery is extremely abominable with the operational environment of cable, when unwrapping wire that the mining conveying machinery is in operation or take-up, cable will be subjected to the friction even the obstruction of ore, thereby make cable frequently be subjected to severe friction, punching press and hard intensity pulling force at work and reverse, the cycle of scrapping is very short, need to change continually, make the mine production cost higher.
With regard to the mining cable product, along with the raising day by day of mining machinery producing capacity and place capacity, the scraper that adopts cable directly to power has obtained a large amount of selecting for use, and therefore, the consumption of the rubber insulation mining cable of the type is also increasing.
The utility model adopts double-deck reinforced layer, one deck is arranged on the outside of conductor, another layer is arranged between inner restrictive coating, the external sheath layer, solved the fracture of cable conduction core effectively, the relatively poor problem of whole tensile property, prolong the useful life of cable, and still kept better elastic and bendability.
Practical content:
This practical purpose provides a kind of mining conveying machinery cable, solves the fracture of cable conduction core, the relatively poor problem of whole tensile property, thus prolonged cable useful life.
This practicality technical scheme as follows:
Mining conveying machinery cable, comprise a plurality of conductor groups, interior reinforced layer, described a plurality of conductor group is vertically placed side by side, described a plurality of conductor group is made of the many mutual stranded bunchys of identical conductor respectively, it is characterized in that: described conductor is enclosed with interior reinforced layer outward respectively, described a plurality of conductor group is wrapped with insulating barrier, and the insulating barrier outside of described a plurality of conductor groups is enclosed with inner restrictive coating, outer reinforced layer, external sheath layer successively.
Described insulating layer material is an ethylene-propylene rubber.
Described inner restrictive coating, external sheath layer material adopt thermoplastic elastomer (TPE).
Reinforced layer adopts the wrapped formation of high-strength nylon band in described, and described outer reinforced layer adopts the aramid fiber braiding to constitute.
This practical selected material is:
(1) conductor.Select zinc-plated reinforced structure for use, the conductor internal layer is selected the stranded strand that forms of unannealed copper covered steel single line for use, the outer stranded tin-coated copper twisted wire of strand, and then wrapped one deck high-strength nylon band.Band both can increase tensile strength, also can play buffer action.
(2) insulation.According to environment for use and cable normal operating temperature, select ethylene-propylene rubber as insulating material, the ethylene-propylene rubber material has remarkable weatherability, anti-ozone, low compression set, good pliability, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent anticorrosive performance, and nontoxic odorless.It is a kind of desirable wind-powered electricity generation cable insulation clad material.Insulation should closely be extruded on the conductor, and section does not have visible bubble of eyesight and impurity, the outward appearance rounding and easily and conductor peel off.
(3) reinforced layer.Select reinforced aramid fiber braiding in the construction of cable for use.Conductor wire core is stressed when spurring in order to reduce mining scraper cable, and cable adopts the primary structure member of aramid fiber braiding.The intensity of aramid fiber is ten times of steel wire and density only is so both to have guaranteed the whole cable pull resistance by steel wire 1/10th, has improved the crushing resistance of cable again, has also alleviated weight.In order to increase the high compression that cable can bear, designed the rubber jacket structure of inside and outside combination.
(4) cable element.The stranded lay ratio of cable core stranding is 12, and the cable core behind the stranding directly extrudes inner sheath (do not have and fill), to prevent the slippage between the cable insulation core, increases the antitorque commentaries on classics performance of cable.
(5) oversheath.Sheath adopts thermoplastic elastomer (TPE) (TPE) material.This material by modification after the low temperature brittleness temperature can reach-65 ℃.By strengthening the soft segment molecule amount and the degree of cross linking, increase pliability, make cable become more soft, thermoplastic elastomer (TPE) (TPE) material has very superior mechanical performance, having good uvioresistant, weatherability, high temperature resistant and have biodegradable environmental-protecting performance again, is a kind of desirable cold resistant cable clad material.When sheath is extruded, should strengthen the radial pressure of mould, extrude tight, solid with assurance.Jacket surface should be smooth, rounding, color and luster basically identical, and section should not have visible bubble of eyesight and impurity.
This practical advantage is:
Of the present utility model simple in structure, easily manufactured, has the excellent electric insulation performance, adopt double-deck reinforced layer, one deck is arranged on the outside of conductor, and another layer is arranged between inner restrictive coating, the external sheath layer, solved the fracture of cable conduction core effectively, the relatively poor problem of whole tensile property has prolonged the useful life of cable, and has still kept better elastic and bendability.
