Abstract
A flexible cable used for a shuttle bus belongs to the technical field of mine cables. The flexible cable comprises three power cores, a pilot core and an outer sheath and is characterized in that the power core comprises a power core conductor; a rubber insulating layer is arranged outside the power core conductor; an insulating shielding layer is arranged outside the insulating layer; the pilot core comprises a pilot core conductor; a rubber insulating layer is arranged outside the pilot core conductor; an insulating shielding layer is arranged outside the insulating layer; and a steel wire rope strengthening element is arranged between the power core and the pilot core. The flexible cable has the beneficial effects of reasonable and simple structure, easy production and manufacture and low cost. The flexible cable also has the characteristics of good flexibility, long service life, stretching resistance, oil resistance and wear resistance, etc.
Description
Technical field
The utility model relates to the mine soft cable technical field, relates in particular to a kind of shuttle and uses flexible cable.
Background technology
Coal is the main energy sources of China, and it and economic construction and people's daily life are closely related, the annual speed increment more than one 8% of the yield of coal in China.Mining Plastic-sheathed Cable is the indispensable auxiliary products of coal industry, along with the continuous progress of mining technique, the colliery to cable require increasingly high.The vehicular cable that shuttles back and forth under the coal mine mainly is the connecting line of shuttle transmission power and signal; In use; All the time be in coiling------reeling again---cycle movement that stretches again that stretches, so cable need possess good flexibility and stretch-resistance.In addition because environment for use is abominable, so it also should have characteristics such as wear-resistant, oil resistant.
Summary of the invention
The purpose of the utility model is to provide a kind of have good flexibility, long service life, stretch-proof, oil resistant, and anti abrasive shuttle is used flexible cable.
For the purpose that realizes the utility model and solve its technical problem and realize through following technical scheme.
A kind of shuttle is used flexible cable; Comprise that three power cores, one keep watch on core and oversheath; It is characterized in that: said power core comprises a power line core conductor, outside said power line core conductor, also is provided with a rubber insulation layer, outside said insulating barrier, is provided with an insulation screen; Said supervision core comprises a pilot wire core conductor, outside said pilot wire core conductor, also is provided with a rubber insulation layer, outside said insulating barrier, is provided with an insulation screen.
In the middle of said power core and said supervision core, also be provided with a steel wire rope reinforcing element.
Be wrapped with a rubber inner sheath at said power core and said supervision core, outside said inner sheath, also be provided with a fibrage shielded layer, outside said screen, also be provided with oversheath.
Characteristics such as the utility model is rational in infrastructure simple, manufactures easily, and cost is low, but also has good flexibility, long service life, stretch-proof, oil resistant, and is wear-resistant.
Description of drawings
Fig. 1 is the utility model: a kind of shuttle is with the structural representation of flexible cable.
