Abstract
The utility model relates to a cable for connecting with electric sources of underground coal mining machines and similar equipment, particularly a shield winding and covering reinforced type rubber sheath soft cable for a coal winning machine. The utility model comprises power wire cores, control wire cores, an inner sheath, a reinforced layer and an outer sheath, wherein a semi-conduction shielding layer is arranged outside an insulation layer of the power wire cores; a winding and covering ground wire extruded and covered with semi-conduction rubber is arranged outside the insulation layer of the control wire cores; the winding and covering ground wire is electrically connected with the semi-conduction shielding layer of the power wire cores. The cable solves the problem that the existing cables made in China restrict the manufacture of the cables with large sections. The utility model has favorable reliability, the cross section of the cable can reach 150MM < 2 >, and the utility model can be matched with the current large coal winning machines, and replaces import cables.
Description
Technical field:
The utility model relates to the used for electric power connection cable of colliery silo shearer and similar devices, and particularly a kind of coal-winning machine shields wrapped reinforced rubber sleeve flexible cable.
Background technology:
At present, the coal-winning machine of domestic production connects with power supply uses cable, and because of its reinforced layer double as ground wire, promptly the ground wire of this cable is the outside at inner sheath, the inside of oversheath, has limited this cross-section of cable.Therefore, for large-scale coal mining unit equipment, 95mm in existing " colliery flame retardant cable " standard
2The needs that present coal-winning machine develops far can not be satisfied in the cross section of cable, so coal enterprises in China, the cable of use all relies on from external import.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve the restriction that existing coal-winning machine feed cable structure is produced electric cable with large cross-section, can shield wrapped reinforced rubber sleeve flexible cable with the coal-winning machine that large-scale coal-winning machine matches and provide a kind of.
The technical scheme that realizes the foregoing invention purpose is: this coal-winning machine shields wrapped reinforced rubber sleeve flexible cable and comprises power core, control core, inner sheath, reinforced layer, oversheath, the insulating barrier of this power core is outside equipped with semiconductive shielding layer, the insulating barrier of this control core is outside equipped with the wrapped ground wire that extrudes semi-conductive rubber, and this wrapped ground wire is electrically connected with the semiconductive shielding layer of power core.
Shield wrapped reinforced rubber sleeve flexible cable according to described this coal-winning machine of this case, have two big characteristics: the one, its ground wire is wrapped in the insulation of control core, extrude semi-conductive rubber then, and there is semiconductive shielding layer the insulation of master core outside, ground wire communicates with main line like this, and cable has good reliability; The 2nd, the cross-section of cable arrives 150mm greatly
2, can match with present large-scale coal-winning machine, to substitute the import cable.
Description of drawings:
Fig. 1 is a kind of cross-section of cable structural representation of the present utility model.
Fig. 2 is an another kind of cross-section of cable structural representation of the present utility model.
Embodiment:
Provide specific embodiment of the utility model below in conjunction with accompanying drawing.
The coal-winning machine that present embodiment provides shields wrapped reinforced rubber sleeve flexible cable and is made of power line core conductor 1, power line core insulation layer 2, semiconductive shielding layer 3, control line core conductor 4, control line core insulation layer 5, wrapped ground wire 6, inner sheath 7, reinforced layer 8, oversheath 9.This power line core conductor 1, the insulating barrier 2 that power line core conductor 1 outside is set, the semiconductive shielding layer 3 that is arranged on insulating barrier 2 outsides constitute the power cores; This control line core conductor 4, the insulating barrier 5 that control line core conductor 4 outsides are set, the wrapped ground wire of semi-conductive rubber 6 that extrudes that is arranged on insulating barrier 5 outsides constitute the control cores; The wrapped ground wire 6 of this control core is electrically connected with the semiconductive shielding layer 3 of power core.
Power core in the present embodiment and control core are three, be bundled together by inner sheath 7, external rings at inner sheath 7 is wound with reinforced layer 8, this reinforced layer 8 can be wrapped reinforced layer (as shown in Figure 1), also can be braiding reinforced layer (as shown in Figure 2), described reinforced layer 8 outer setting have oversheath 9.
