Abstract
The utility model discloses a bending-resistant rubber-sheathed flat cable for a coal conveyer winding drum. A cable core is formed by parallelly arranging at least three insulation wire cores which are provided with insulation shielding layers respectively. The cable core is externally extruded with an outer sheath. Each of the insulation wire cores is composed of a conductor, a conductor shielding layer and an insulating layer from inside to outside. The center of each conductor is provided with an aramid silk fiber reinforcement core. The bending-resistant rubber-sheathed flat cable for the coal conveyer winding drum is a coal conveyer-dedicated cable which is good in softness, high temperature resistant, corrosion resistant, wear resistant, flame retardant and the like, and excellent in bending performance; the wire cores are not easy to break; and the bending-resistant rubber-sheathed flat cable is applicable to special work environments.
Description
Technical field:
The utility model relates to a kind of counter-bending conveyer reel rubber cover flat cable, belongs to technical field of electric wires and cables.
Background technology:
China is vast in territory, aboundresources, and along with the development of China's economic construction, the use of conveyer tool is more and more, and especially the places such as metallurgy, coal yard, chemical industry need a large amount of conveyer tools.
Handling at transport field coal are important links, the past we adopt the artificial efficiency of loading and unloading very low, and we generally load and unload with conveyer now.Due to conveyer, in cargo handling process, be to move around in orbit rather than actionless, conveyer and electrical power control cabinet are far, need to connect with very long cable.Conveyer moves around in the course of the work, when conveyer advances, cable can be pulled out from cylinder by conveyer, and conveyer while retreating cable can be reeled by cylinder, cable inner ring when bending is subject to very large pressure and the outer ring of cable is subject to very large pulling force, when conveyer is walked, cable is formed again to very large longitudinal pulling force, therefore the conveyer cable core is easy to fracture, so just require conveyer should possess the defencive function to cable bend, and conveyer is under condition of work, this obviously is difficult to accomplish, therefore just must consider to make cable itself there is certain counter-bending ability, i.e. cable bend certain radius at a certain temperature, several thousand times even up to ten thousand times continuously, cable still can keep normal operation, conductor does not break, insulation and sheath material be cracking not also, also require cable to have high temperature resistant, corrosion-resistant, wear-resisting, the performance such as fire-retardant, also there is no up to now a kind of conveyer private cable with above performance.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of soft degree good, core is easy fracture not, has again characteristic and the conveyer private cables that possess excellent bending property such as high temperature resistant, corrosion-resistant, wear-resisting, fire-retardant, to adapt to special operational environment.
The utility model technical solution problem adopts following technical scheme:
Counter-bending conveyer reel rubber cover flat cable, adopt at least three insulated wire cores with insulation screen formation cable core that be arranged in parallel, at described cable core skin, is extruded with oversheath; Described insulated wire cores from-inner-to-outer consists of conductor, conductor shield and insulating barrier, and described conductor center is established and spun synthetic fibre silk fiber strengthening core.
Described insulating barrier and described oversheath adopt silicon rubber to extrude formation.
Described insulation screen adopts metal knitted in described insulating barrier skin, the double earth connection of doing of insulation screen.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the conductor of the utility model cable is the zinc-plated soft copper conductor of the 6th class, same employing high strength is spun the synthetic fibre silk fiber and is made tension silk strengthening core, the thin tinned wird thigh strand of multiply and multiple strand, and be a burst strand version identical with twisting again direction, flexibility and the ductility of cable have been improved, cable core becomes the present non-stranded flat structure that is arranged in parallel by original circular lay configuration, cable inner ring core of cable when bending of circular lay configuration is subject to very large pressure, the outer ring core of cable is subject to very large pulling force, and flat structure cable core is arranged in parallel, pressure and pulling force that the core of cable cable when bending is subject to will reduce greatly than the cable of circular lay configuration, so the flexibility of cable is good, the little cable that is of value to of bending radius is reeled on cylinder, conductor can not be pulled off with curved disconnected, extended the useful life of cable.
2, the insulating barrier in the utility model is to have high anti-tear and silastic material excellent electrical properties to extrude and form, the double earth connection of doing of metal knitted shielding for insulated wire cores, also just increased the outer double metal knitted screen of earth connection and the contact-making surface of power line core insulation done of insulated wire cores, when at cable insulation, any one sustains damage like this, whole equipment all can cut off the power supply immediately, has improved the security performance of equipment.
3, the utility model oversheath is that the silastic material anti-tear, high temperature resistant, corrosion-resistant, wear-resisting, fire-retardant with height made, so mechanical strength is brought up to present 12Mpa by original 5Mpa, percentage elongation is brought up to present 450% by original 150%, tear strength is brought up to present 7N/ ㎜ by original 1～2N/ ㎜ (trousers type rectangularity); There is good fire resistance; Cable is after oil, acid, caustic corrosion performance test, and product is not subject to any damage.
4, the utility model has good bending resistance, electrical property and the high performance such as anti-tear, high temperature resistant, corrosion-resistant, wear-resisting, fire-retardant, is particularly suitable for using at the conveyer of mobile occasion.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 spins synthetic fibre silk fiber strengthening core, 2 conductors, 3 conductor shields, 4 insulating barriers, 5 insulation screens, 6 oversheaths.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1, the counter-bending conveyer reel rubber of the present embodiment cover flat cable, adopt at least three insulated wire cores with insulation screen 5 formation cable core that be arranged in parallel, at the cable core skin, is extruded with oversheath 6; The insulated wire cores from-inner-to-outer consists of conductor 2, conductor shield 3 and insulating barrier 4, and conductor 2 centers are established and spun synthetic fibre silk fiber strengthening core 1.
In specifically arranging, insulating barrier 4 and oversheath 6 adopt silicon rubber to extrude formation.Insulation screen 5 adopts metal knitted in insulating barrier 4 skins, the double earth connection of doing of insulation screen 5.
The conductor of the utility model cable is the zinc-plated soft copper conductor of the 6th class, performance meets the zinc-plated soft copper conductor of GB/T3956-2008 the 6th class, same employing high strength is spun the synthetic fibre silk fiber and is made the tension silk, multiply fine copper wire thigh strand and multiple strand, and be burst strand and multiple strand version in the same way, form the conductor comprised containing the tension silk, adopt the mode of co-extrusion to form conductor shield 3 and insulating barrier 4, adopt the double earth connection of doing of metal knitted screen to form insulation screen 5, adopt at least three insulated wire cores with insulation screen formation cable core that be arranged in parallel, extrude oversheath 6.
