Abstract
The invention discloses a flame-retardant control cable for a coal mining machine. The flame-retardant control cable for the coal mining machine includes a plurality of power core conductors and a plurality of control core conductors which are wrapped by insulation layers, wherein the insulation layers of the power core conductors are wrapped by shielding layers, a plurality of carbon fiber ropes are arranged in each control core conductor, the control core conductors wrapped by the insulation layers are stranded into a harness, the harness is then stranded with the power core conductors wrapped by the shielding layers around an earthing core conductor to form a cable core, and the cable core is wrapped by a jacket layer. The flame-retardant control cable for the coal mining machine has a novel and reasonable structural design; carbon fibers are used for filling conductor cores, and the cable core is formed through double stranding, so that the volumes of the conductor cores are not enlarged, the conductor softness is not influenced, the strength of control cores of the cable for the coal mining machine and the overall strength of the cable core are greatly enhanced, and the service life of the cable is prolonged.
Description
Technical field:
The present invention relates to the control cable field, relate in particular to a kind of flame retardant type coal-winning machine and use 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.
Summary of the invention:
In order to solve prior art problems, the purpose of this invention is to provide a kind of flame retardant type coal-winning machine and use control cable, improved the structural strength of cable, do not influence overall performance.
Technical scheme of the present invention 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%.
Advantage of the present invention is:
Structural design of the present invention 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 a structural representation of the present invention.
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.
