Abstract
The utility model provides a metal shielded zonary rubber jacketed flexible cable of a coal winning machine. The rubber jacketed flexible cable comprises a sheath, a control cable and three power cables, wherein, the control cable and the power cables are arranged in the sheath; each cable comprises a cable core, an insulating layer and a shielding layer; and the cable core is formed by stranded metal wires. The utility model is characterized in that the control cable and the power cables are arranged in the flat sheath in a parallel manner; a radio-frequency cable core or an optical fiber combination is arranged in the center of the control cable; the radio-frequency cable core or the optical fiber combination and the peripheral control cable core are stranded concentrically so as to forma unit; the insulating layer made of fluoroplastic is arranged at the exterior of the radio-frequency cable core; and a layer of FEP is coated at the exterior of the optical fiber combination. The utility model improves the current capacity of the cable, reduces the use cost of the cable, ensures that signals can be transmitted more accurately through the cable, prolongs the service life, improves the operation efficiency of the coal winning machine, and enhances the production efficiency.
Description
Technical field
The utility model relates to a kind of compound control power supply flexible cable for coal mining machine, particularly discloses the banded rubber sleeve flexible cable of a kind of coal-winning machine metallic shield.
Background technology
At present, known soft cable of coal mining machine inside is the round cable of columnar arrangement in the shape of a spiral, and the control core is the conventional insulated single wire of 450/750V.And coal-winning machine bending radius in actual motion is little, is an objective environment that can't change,, can cause the towing of cable control core to be broken like this, whole cable can't use, and causes the wasting of resources.Round cable makes into to get rid of the too small obstacle of bending radius naturally behind the flat cable, has improved the ampacity of master core simultaneously.
Set up 3～20 control power lines in the time of cable carrying coal-winning machine electrical source of power, to satisfy the electric system of present coal-winning machine.Along with situation, the coal-winning machine situation of technological progress must develop to Digital Control, realize that coal-winning machine automation control and the operation of remote monitor coal-winning machine are dynamic, 3 pairs of optical fiber or 1 radio frequency core are set up in electric cable for coal mining machine inside for this reason, to satisfy the required propagation function of coal-winning machine photo-electric control.
Summary of the invention
The purpose of this utility model is the problem that exists at above-mentioned prior art, a kind of ampacity that can not only reach accurate transmission coal-winning machine control signal, raising cable is provided, and can improves the soft cable of coal mining machine banded rubber sleeve flexible cable of compound control power supply coal-winning machine metallic shield in useful life.
The utility model is achieved in that the banded rubber sleeve flexible cable of coal-winning machine metallic shield, comprise control cable and power cable in sheath and the sheath, cable is made up of the stranded core that forms of plain conductor, insulating barrier and screen, it is characterized in that: described control cable and power cable are arranged in parallel in the flat sheath, be provided with a control cable and three power cables in the described sheath, be provided with radio frequency core or optical fiber combination centering in the described control cable, and control core on every side with unit of the stranded composition of core.Described radio frequency core peripheral hardware has fluoroplastics to make insulating barrier.Described optical fiber combination coats one deck perfluoroethylene-propylene outward.The anti-resistance of radio frequency core characteristic is selected a kind of in 50 Ω, 75 Ω or 100 Ω.
The beneficial effects of the utility model are: the ampacity of cable has been improved.As round cable 3 * 70mm
2Ampacity is 224A, now uses flat cable 3 * 50mm
2Can reach ampacity 224A.Reduced the cost that uses cable.Overcome the single signal transmission of traditional soft cable of coal mining machine simultaneously, guarantee the special performance that control line does not rupture, use the banded rubber sleeve flexible cable transmission signals of the utility model more accurate, improved 50% useful life, improve the coal-winning machine operational paradigm, enhanced productivity 30%.
