Abstract
The utility model discloses a pulling flexible cable used for a coal cutter. The pulling flexible cable comprises a plurality of flexible copper conductors, and aluminium foil taped coverings and EP rubber insulating layers are respectively wrapped outside the plurality of flexible copper conductor in sequence to form insulating wire cores. The insulating wire cores wrap a center of a hollow elastic layer to form a cable core. A section of the elastic layer is in a star shape. An inner restrictive coating, a shielding layer, a composite reinforced layer are wrapped outside the cable core in sequence. The composite reinforced layer comprises a braiding layer and a restrictive coating, and is formed by weaving nylon yarns and aramid fibers, with knitting tightness no less than 88%. The braiding layer is formed in the restrictive coating through extrusion. The cable is reasonable in design. The elastic layer in the center of the cable core can adapt to external impact and protect the conductors from being damaged. The composite reinforced layer disposed outside the shielding layer makes up defects that an ordinary rubber jacketed flexible cable cannot be used for pulling.
Description
Technical field:
The utility model relates generally to Plastic-sheathed Cable, specifically is that a kind of coal-winning machine is with drawing flexible cable.
Background technology:
In the collecting work process in colliery, owing to equipment itself needs to move, so but in the colliery, need to use in a large number double as to draw the Plastic-sheathed Cable of usefulness.Cable as mining coal-winning machine uses will draw movement in use, if there is not strengthening core, cable is in long-term the use, and is impaired easily through pulling force, reduces the useful life of cable.
The cable that mining coal-winning machine uses, because equipment itself needs to move in the course of work, cable also must move by the equipment of following, and requires cable not only to want soft gentle, more certain pulling force will be arranged.Therefore, but the Plastic-sheathed Cable of double as traction usefulness also becomes the particular customer inevitable choice.And national standard or industry standard to this type of cable all less than regulation, use cable also not possess the double as traction function on the market.
The utility model content:
The utility model purpose provides a kind of coal-winning machine with the traction flexible cable, is applicable to large-scale traveling hoist and harbour machinery mobile devices such as coal mining, phenomenon of rupture can not occur in the distraction procedure, and softness is superior.
The utility model is achieved through the following technical solutions:
Coal-winning machine is with drawing flexible cable, include several soft copper conductors, it is characterized in that: described several soft copper conductors are enclosed with the aluminium foil lapping layer outward successively respectively, ethylene propylene rubber insulated layer constitutes insulated wire cores, insulated wire cores is with the vertical formation cable core of putting in the center of parcel hollow elastic layer, the cross section of elastic layer is star, cable core is enclosed with inner restrictive coating, screen, compound reinforced layer outward successively, compound reinforced layer comprises that braid, restrictive coating constitute, adopt the braiding of Polyamide Yarns and aramid fiber silk to constitute, count is not less than 88%, and braid process extrusion moulding is in restrictive coating.
Described coal-winning machine is characterized in that: described elastic layer employing natural rubber elastomer extrusion moulding with the traction flexible cable.
The utility model has the advantages that:
It is injury-free that the utility model reasonable in design, the elastic layer at cable core center can adapt to foreign impacts protection conductor, is provided with compound reinforced layer outside the screen, and having remedied common rubber sleeve flexible cable can not be as the defective of traction usefulness.
Description of drawings:
Accompanying drawing is cross section structure figure of the present utility model.
Embodiment:
Referring to Fig. 1:
Coal-winning machine is with drawing flexible cable, include several soft copper conductors 1, several soft copper conductor 1 outer aluminium foil lapping layer 2, ethylene propylene rubber insulated layer 3 formation insulated wire cores of being enclosed with respectively successively, insulated wire cores is with the vertical formation cable core of putting in the center of parcel hollow elastic layer 4, the cross section of elastic layer 4 is star, cable core is enclosed with inner restrictive coating 5, screen 6, compound reinforced layer outward successively, compound reinforced layer comprises that braid 7, restrictive coating 8 constitute, adopt the braiding of Polyamide Yarns and aramid fiber silk to constitute, count is not less than 88%, and braid 7 process extrusion moulding are in restrictive coating 8.
Claims (2)
