Abstract
The invention discloses a high-strength flexible drag chain cable. The cable comprises a main cable core, a secondary cable core, a filling layer for extruding the main cable core and the secondary cable core, a weaved reinforcing layer for wrapping the filling layer and an outer sheath for wrapping the weaved reinforcing layer, wherein the main cable core comprises a conductor, a reinforced core arranged in the center of the conductor and a main insulating layer for lapping the conductor; the secondary cable core comprises a reinforced core and a secondary insulating layer for lapping the reinforced core, wherein the reinforced core adopts the Kevlar reinforced core; the conductor is formed by copper wires and steel wires in a twisting manner; and the weaved reinforcing layer is made from aramid fibers. The overall cable, after being formed by the cable cores in the twisting manner, is high in flexibility, good in anti-rocking and anti-bending performance, and ultra-high in tensile strength, so that the service life and the safety of the cable are improved.
Description
Technical field
The present invention relates to cable production art, be specifically related to a kind of high-strength flexible drag chain cable.
Background technology
Cable industry is the second largest industry being only second to automobile industry of China, its inner core of drag chain cable that the mobile occasion such as current existing industrial machinery, robot, servomotor, geological prospecting uses is copper core substantially, but developing rapidly and its rapid popularization of applying along with cable industry, the performance requirement of people to cable is strictly more next, and the copper core of routine is due to its good ductility, make it be easy to be elongated and break, can not meet the demand in high-strength working situation.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of structure simple, high-strength flexible drag chain cable applied widely.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of high-strength flexible drag chain cable, comprise main push-towing rope core, secondary cable core, the packed layer extruding main push-towing rope core and secondary cable core, the braiding reinforced layer of parcel packed layer, the oversheath of parcel braiding reinforced layer, described main push-towing rope core comprises conductor, is arranged on the strengthening core of conductor central authorities and the main insulating layer of wrapped conductor; Described secondary cable core comprises the secondary insulating barrier of strengthening core and wrapped strengthening core; A secondary cable core is provided with between described two adjacent main push-towing rope cores.
Described strengthening core adopts Kev to draw strengthening core to make, because this density of material is low, intensity is high, good toughness, high temperature resistant, be easy to processing and shaping, its intensity is 5 times of equal quality iron and steel, so the cable core of cable can be made when being subject to external pull, the firm not easy fracture of cable conductor, thus extend the useful life of cable.
Described conductor adopts copper and steel wire is stranded forms, and because steel wire has good warping resistance performance, after the copper twisted synthesizing cable that ductility is good, makes cable core have good warping resistance performance.
Described main insulating layer, secondary insulating barrier and oversheath adopt polythene PE, thermoplastic elastomer (TPE) TPE, TPUE rubber TPU or polyvinylchloride material to make, adopt these insulating material, not only increase the mechanical strength of cable, and can moistureproof, anticorrosion, there is good fire resistance.
Described packed layer adopts polypropylene rope, cordage or rubber bar to make, and can ensure the rounding of cable, its inner cable core structure is stablized, prevents from use rocking, work the mischief.
Described braiding reinforced layer adopts aramid fiber yarn to make, and because aramid fiber yarn has good insulating properties and ageing resistance, and the cable that the intensity of its superelevation makes it form has extraordinary tension compressive property.
Compared to prior art, high-strength flexible drag chain cable of the present invention, by arranging main push-towing rope core and secondary cable core, and main push-towing rope core and secondary cable core center are provided with Kev draws strengthening core, the conductor of main push-towing rope core have employed copper wire and the stranded formation of steel wire, and inside oversheath, be provided with one deck braiding reinforced layer, make whole cable have good flexibility after cable core twisted synthesizing cable, anti-to wave, the tensile strength of warping resistance performance and superelevation, extend useful life and the security performance of cable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is the schematic cross-section of high-strength flexible drag chain cable of the present invention;
Fig. 2 is the vertical view of high-strength flexible drag chain cable of the present invention.
Embodiment
As shown in Figure 1-2, for a kind of high-strength flexible drag chain cable, comprise main push-towing rope core, secondary cable core, the packed layer 6 extruding main push-towing rope core and secondary cable core, the braiding reinforced layer 7 of parcel packed layer 6, the oversheath 8 of parcel braiding reinforced layer, wherein main push-towing rope core is by conductor 2, and the main insulating layer 3 of the strengthening core 1 and wrapped conductor 2 that are arranged on conductor 2 central authorities forms; Secondary cable core is made up of the secondary insulating barrier 5 of strengthening core 4 and wrapped strengthening core 4; A secondary cable core is provided with between two adjacent main push-towing rope cores.
What wherein strengthening core 1 and strengthening core 4 adopted is that Kev draws strengthening core, for strengthening the tensile strength of cable conductor.
Wherein conductor 2 is made up of copper wire and the stranded multiply stock core of steel wire, the good ductility of copper wire and have the good flexing resistance of flexible nature steel wire, the stock core making it stranded can have good resiliency by when collision and shock loading at work.
Wherein main insulating layer 3 and secondary insulating barrier 5 adopt PE material to make, and oversheath 8 adopts PVC material to make, and they have protection against the tide, grease proofing, anticorrosion, the aging and resistance to combustion of solar control and mechanical protection effect.
Wherein packed layer 6 adopts rubber bar material to make, and extrudes main push-towing rope core and secondary cable core, makes its relative position not stressed with the external world and changes.
Wherein weaving reinforced layer 7 adopts aramid fiber yarn material to make, and for strengthening the ability of resisting longitudinal pull-off force further, improves the mechanical strength of cable.
Above content is in conjunction with concrete preferred implementation further description made for the present invention; can not assert that specific embodiment of the invention is confined to these explanations; for those skilled in the art; without departing from the inventive concept of the premise; some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
