Control line in electric cable for coal mining machine mainly plays the effect of signal monitoring.Control cables core in traditional electric cable for coal mining machine adopts restraints the structure that tangles.Due in cable running because being subject to the multiple effect of stress such as frequent bending, coal cinder punching press, various mechanical presses, stretching; easily cause the conductor wire core fracture in control line; once conductor wire core fracture; to lose monitoring and protection effect; cause equipment to stop operating; have a strong impact on normal production, cause very large economic loss.In addition, the sheath neoprene in traditional electric cable for coal mining machine or haloflex rubber mixture, not only contain halogen, also contain the heavy metals such as plumbous cadmium, when manufacture, use and waste treatment, can produce the public hazards such as a large amount of corrosivity halogen acid gas, dioxin, the requirement that does not reach environment-friendly cable.
Utility model content
Technical problem to be solved in the utility model is to overcome defect of the prior art, and a kind of shielding rubber jacketed flexible cable for coal mining machine is provided, and has the performances such as high strength, high stretching, high abrasion, oil resistant, heat-resisting, environmental protection.
For solving the problems of the technologies described above, the utility model provides a kind of shielding rubber jacketed flexible cable for coal mining machine, comprise power core, control core, core, twining package tape and oversheath, power core comprises power line core conductor and is extruded in the power line core insulation outside power line core conductor, the outer extruded insulation shielding of power line core insulation, control line core conductor is the conductor wire core that the strengthening core of stone dead wire or aramid fiber yarn composition weaves copper strand wire outward.
As further improvement of the utility model, cable conductor is centered by a ground core, with three power cores and control cable core, be centered around outer stranded forming, the outer wrapped twining package tape of cable conductor, twining package tape peripheral hardware is extruded the oversheath forming by ethylene-octene mixture.
As further improvement of the utility model, power core comprises power line core conductor and is extruded in the power line core insulation outside power line core conductor, at power line core insulation peripheral hardware, be useful on the semiconductive shielding layer that solves screen and insulating barrier compatibility and rippability difficulty, semiconductive shielding layer is the semiconducting rubber that ethylene-vinyl acetate fat and hydrogenation nitrile rubber form; Power line core insulation is the insulation rubber that ethylene-octene mixture and ethylene-propylene rubber form.
As further improvement of the utility model, control core and comprise the control line core conductor in center and be extruded in the control line core insulation outside control line core conductor, after many control core twisted synthesizing cables, extrude control core coating layer formation and control cable core; Control line core insulation is the insulation rubber that ethylene-octene mixture and ethylene-propylene rubber form; Ground core comprises ground wire core conductor and wrapped twining package tape outside ground wire core conductor.
Compared with prior art, the beneficial effect that the utility model reaches is embodied in:
1, the utility model control line core conductor adopts stone dead wire or aramid fiber yarn as the strengthening core of manufacturing conductor wire core, by weaving copper wire woven to strengthening core, complete the manufacture of conductor wire core, make the tensile strength of core reach 1000MPa, effectively avoided the problem of conductor wire core easy fracture.
2, oversheath of the present utility model adopts and take the rubber design of mixture that ethylene-octene is base and be prepared from, and is fuming low, and can reuses during cable fire.
