Description

A kind of anti-interference counter-bending rubber covered flexible electric cable for coal mining
Technical field:
The utility model relates to a kind of anti-interference counter-bending rubber covered flexible electric cable for coal mining, belongs to technical field of electric wires and cables.
Background technology:
Coal is one of China's important energy source, along with China's economic construction development electric power requirement strengthens day by day, the coal consumption is also increasing, and coal is to be present in natural a kind of fossil energy, and at China's reserves, very greatly especially the coal resources in the Xinjiang of China, Inner Mongol, Shanxi are abundant especially.
Coal is a kind of mineral resources at occurring in nature, is imbedded in very dark underground.The pre-peaceful liberation period we with the man-made recovery now China's coal mining industry all with coal-winning machine, exploit.Due to coal-winning machine, in the coal mining process, be to move around rather than actionless, coal-winning machine and electrical power control cabinet are far, need to connect with very long cable.Coal-winning machine all around moves in the coal mining process, and when coal-winning machine is adopted foremost, at this moment coal-winning machine will retreat and move to left, and in retreating the process of moving to left, the serious bending of the figure of eight and serpentine and dilatory can occur cable.Cable inner ring core of cable when bending is subject to very large pressure and the outer ring core of cable is subject to very large pulling force, when coal-winning machine is walked, cable is formed again to very large longitudinal pulling force.Electric cable for coal mining machine is divided into the power core and controls core, and owing to controlling, core is thinner is easy to fracture, and the whole machine of interference that coal-winning machine also is subject to other power supply signal when work in addition all can not turn round.So just require coal-winning machine system on the one hand should possess the defencive function of cable bend and possess certain antijamming capability, coal-winning machine is under this severe condition in down-hole, this obviously is difficult to accomplish, what must consider on the other hand is that cable itself should have certain counter-bending ability and antijamming capability, i.e. cable bend certain radius under certain condition, several thousand times even up to ten thousand times continuously, cable still can keep normal operation, cable conductor particularly control line core conductor does not break, the insulation and sheath material also not cracking also certain antijamming capability to be arranged.Also there is no up to now a kind of coal-winning machine private cable with excellent bending resistance and antijamming capability.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide the good antijamming capability of a kind of soft degree strong, control core and be difficult for fracture, not only there is fire-retardant, oil resistant, the characteristic such as high temperature resistant, wear-resisting to adapt to different operational environments, and possess the coal-winning machine private cable of excellent bending property and antijamming capability.
The utility model technical solution problem adopts following technical scheme:
A kind of anti-interference counter-bending rubber covered flexible electric cable for coal mining, form side by side cable conductor by controlling core and power core, the outermost layer that be surrounded with successively the cable inner sheath outside described cable conductor, be woven with the wire armoring layer, is surrounded with silvalin lapping layer, cable is extruded with cable jacket; Described control core is provided with control line core conductor, control line core insulation layer, metal screen layer, semiconductive shielding layer from inside to outside successively, and the layering of described control line core conductor is wrapped in to be spun on synthetic fibre silk fiber strengthening core; Described power core is provided with power line core conductor, power line core insulation layer and insulation screen from inside to outside successively.
The double ground wire core conductor of doing of the metal screen layer of described control core.
Described control line core insulation layer, power line core insulation layer adopt ethylene propylene diene rubber to make insulating barrier.
Described power line core conductor consists of the thin tinned wird thigh of multiply strand and multiple strand, and burst strand is with to twist again direction identical.
Described cable jacket is the neoprene oversheath.
Described wire armoring layer is by annealed copper wire and high-tensile steel wires are stranded forms.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the control line core conductor has adopted high strength to spin the synthetic fibre silk fiber and has made the tension silk, and this tensile strength of spinning the synthetic fibre silk fiber is 2 times of steel wire; Its percentage elongation is only 3 ~ 4%, and high temperature resistant.Be wrapped in the method production control core conductor spun on the synthetic fibre silk fiber with the tin annealed copper wire layering, pitch is very little, and rear its length of conductor monofilament expansion is 1.3 times of raw footage; Controlling core adopts ethylene propylene diene rubber to make insulating barrier, the ground core is divided equally to rear first bundle strand to be stranded on the control core again, the double metal screen layer of doing of ground core, extrude semiconductive shielding layer in metallic shield, thus effectively avoided the control line core conductor be pulled off with curved disconnected while honor strong antijamming capability.
2, the control core in the utility model itself has certain drawing-resistant function on the one hand, the double metal screen layer of doing of core has superpower antijamming capability on the other hand, the power line core conductor adopts the thin tinned wird thigh strand of multiply and multiple strand, and be a burst strand version identical with twisting again direction, extruded insulation screen after the ethylene propylene diene rubber extruded insulation for the power core utilizes the wire armoring reinforced layer to play interference antistatic and that the inhibition master core produces to external world simultaneously.
3, the utility model is that to take fire-retardant, oil resistant, high temperature resistant, wear-resisting, waterproof neoprene be material as the external sheath layer of outer protection, has greatly improved cable in underground moving useful life, and cable can all around move freely with coal-winning machine.
4, the utility model is mainly used in coal-winning machine, and cable can move freely, and cable can move freely with coal-winning machine, brings up to the useful life of controlling core original more than 10 times.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
