Abstract
The utility model discloses a flame-retardant type control cable for a coal winning machine. The control cable comprises a plurality of power line core conductors and a plurality of control line core conductors which are wrapped by insulating layers, wherein, shielding layers are respectively wrapped outside the insulating layers of the plurality of power line core conductors; a plurality of carbon fiber ropes are respectively arranged in the plurality of control line core conductors; the plurality of control line core conductors comprising the insulating layers are mutually twisted to form a bundle and then twisted again with the plurality of power line core conductors wrapped by the shielding layers to form a cable core by using a grounding line core as a center; and a sheath layer is wrapped outside the cable core. The control cable has the advantages that the structural design is novel and reasonable, and carbon fiber is utilized as fillers of conductor line cores which are twisted twice to form the cable core, so that the volumes of the conductor line cores are not increased, the flexibility of the conductors are not influenced, the strength of the control line cores and the integral strength of the cable core of the cable of the coal winning machine are greatly improved, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the control cable field, relates in particular to a kind of flame retardant type coal-winning machine and uses control cable.
Background technology:
The mining flame-retardant electric cable for coal mining machine is to supply with and the signal transmission for the normal operation of silo shearer unit provides electric power specially.Electric cable for coal mining machine is made up of power transmission core and control signal transmission core, since frequent crooked in the normal use of electric cable for coal mining machine, cause the control core to open circuit easily, make cable normally to move, have a strong impact on the useful life of cable.For solving the problem of the disconnected core of electric cable for coal mining machine short circuit, cables manufacturing producer generally adopts the method that increases control core cross section, minimizing control core laying up pitch to improve.But this method can't finally solve the disconnected core problem of control core.
That carbon fiber has is in light weight, volume is little, flexibility good, intensity is high, thermal conductivity and conductivity between metal, nonmetal, the particularly intensity of carbon fiber be steel 7-9 doubly.Utilize carbon fibre material stranded with the control cable conductor thread core; Make carbon fiber fill as conductor thread core; The flexibility that does not increase the volume of conductor thread core and do not influence conductor; Can improve simultaneously the intensity of electric cable for coal mining machine control core greatly, solve the problem that electric cable for coal mining machine control core opens circuit.
The utility model content:
In order to solve prior art problems, the purpose of the utility model provides a kind of flame retardant type coal-winning machine and uses control cable, has improved the structural strength of cable, does not influence overall performance.
The technical scheme of the utility model is following:
The flame retardant type coal-winning machine is used control cable; The several power line core conductors and the several control line core conductor that comprise the wrap insulate layer; The insulating barrier of several power line core conductors is enclosed with screen outward respectively; It is characterized in that: be respectively equipped with several carbon fiber ropes in described several control line core conductors; The mutual stranded bunchy of several control line core conductors that comprises insulating barrier, the several power line core conductors with several parcel screens behind the bunchy are the stranded once more formation cable core in center with the earth connection core conductor, cable core is wrapped with restrictive coating.
Described flame retardant type coal-winning machine is used control cable, it is characterized in that: described screen adopts the tin plated steel wire braiding to constitute, and count is not less than 85%.
The utility model has the advantages that:
The utility model structural design is novel, reasonable; Utilize carbon fiber to fill as conductor thread core; Twice stranded formation cable core; The flexibility that does not increase the volume of conductor thread core and do not influence conductor improves the intensity of electric cable for coal mining machine control core and the bulk strength of cable core greatly, has prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The flame retardant type coal-winning machine is used control cable; The several power line core conductors 1 and several control line core conductors 3 that comprise wrap insulate layer 2; The insulating barrier 2 outer screens 4 that are enclosed with respectively of several power line core conductors 1; Be respectively equipped with several carbon fiber ropes 5 in several control line core conductors 3; Comprise several control line core conductors 3 mutual stranded bunchys of insulating barrier 2, the several power line core conductors 1 with several parcel screens 4 behind the bunchy are the stranded once more formation cable core in center with earth connection core conductor 6, and cable core is wrapped with restrictive coating 7.
Screen 4 adopts the tin plated steel wire braiding to constitute, and count is not less than 85%.
