Abstract
The utility model discloses a photoelectric composite mine rubber-sheathed soft cable which comprises power wire core conductors, control wire core conductors and an optical fiber unit. The outside of each power wire core conductor is coated with a semiconducting layer, an ethylene propylene rubber insulation layer, an insulation shielding layer and a metal shielding layer in turn. The power wire core conductors which are coated with the metal shielding layers are twisted into a bundle to form a power cable core. The outside of each control wire core conductor is coated with an ethylene propylene rubber insulation layer to form an insulation wire core. Each two insulation wire cores are mutually twisted into a bundle and a lapping shielding layer is arranged outside the bundle to form a control cable core. The control cable core and the optical fiber unit are distributed outside the power cable core in the shape of a Chinese character 'pin' to form a comprehensive cable core. A rubber inner sheath layer, a strengthening layer and a rubber outer sheath layer are arranged outside the comprehensive cable core in turn. The photoelectric composite mine rubber-sheathed soft cable provided by the utility model not only can carry out power traction power supply for underground high power and high voltage mining devices, but also can realize underground high power and high voltage mining device remote control and information transmission, so that the running of a underground main mining device is visible and controllable on the ground.

Technical field:
The utility model relates to mining cable, relates in particular to the compound rubber sheathed flexible cable for mine of a kind of photoelectricity.
Background technology:
Along with the raising of China's coal-mine Mechanion, a large amount of new technologies, new equipment are constantly put in the middle of the coal production, and especially some application high-power, the voltage levels extractive equipment make coal production ability and technical equipment obtain tremendous development.
At present, those are high-power, the used power traction cable of voltage levels extractive equipment mostly is the single structure that three power cores add a ground core (or with ground core trisection), do not comprise control core and fiber unit, be difficult to extractive equipment is carried out Long-distance Control, communication and aboveground visual intelligent dynamically production management.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides the compound rubber sheathed flexible cable for mine of a kind of photoelectricity, can be high-power to those of down-hole, the high voltage extractive equipment carries out the power traction power supply, can realize again that those are high-power in the down-hole, high voltage extractive equipment Long-distance Control and communication, it is aboveground visual, aboveground controlled that the main extractive equipment in down-hole is moved.
The technical solution of the utility model is as follows:
The compound rubber sheathed flexible cable for mine of photoelectricity, power line core conductor, control line core conductor, fiber unit, it is characterized in that: described power line core conductor is coated with semi-conductive layer, ethylene propylene rubber insulated layer, insulation screen, metal screen layer outward successively, and the stranded bunchy of the power line core conductor of clad metal screen consists of the power cable core; Described control line core conductor is coated with ethylene propylene rubber insulated layer and consists of insulated wire cores, and per two thoroughly do away with the mutual stranded bunchys of edge core and are provided with lapped shielding layer in the outside and consist of the control cable core; The described power cable core outside is distributed with the control cable core in a triangle, fiber unit consists of comprehensive cable core, and comprehensive cable core is provided with reinforced layer, the rubber external sheath layer of rubber inner restrictive coating, antitorque netted braiding formation outward successively.
The compound rubber sheathed flexible cable for mine of described photoelectricity is characterized in that: described lapped shielding layer adopts the wrapped formation of two-sided semi-conductive rubber strap.
The compound rubber sheathed flexible cable for mine of described photoelectricity is characterized in that: described power line core conductor nominal cross is not less than 25mm
2, control line core conductor nominal cross is not less than 2.5mm

The utility model fiber unit standard model is that other configurations of multimode 62.5/125(can be selected as required).Its rated operational voltage can be divided into four kinds of 3.6/6kV, 6/10kV, 8.7/15kV, 12/20kV, it can be high-power to those of down-hole, the high voltage extractive equipment carries out the power traction power supply, can realize again that those are high-power in the down-hole, high voltage extractive equipment Long-distance Control and communication, it is aboveground visual, aboveground controlled that the main extractive equipment in down-hole is moved.
The utility model has the advantages that:
1, power traction cable, control cables and fiber unit three-in-one component formula structural design
The structural change of the utility model cable traditional colliery underground high-power, high voltage extractive equipment power cable, control cables separate the Design Mode that uses with fiber unit, adopt power cable, control cables and the three-in-one compages of fiber unit.This three-in-one structural design makes it have the triple functions of supply of electric power, electrical control and optical fiber communication, power cable, control cables, the optical cable that can replace same line arrangement fully, saved the down-hole route resource, reduce manufacturing cost expense, underground construction expense, reduced comprehensive cost and investment and the later stage route maintenance work of down-hole project.
2, core design
The ground core of high-power, the used power traction cable of voltage levels extractive equipment of tradition is many to be placed among the power core gap with power core stranding or with ground core trisection as four-core.The utility model cable is knitted to ground core trisection on the insulation semi-conductive layer of power core, makes the ground core have the dual-use function of ground protection and metallic shield, reduces and prevents that the power core is to the interference of control core.
3, control cables core design
The utility model arranges four control cores, and is divided into two groups and fiber unit and places respectively between three power core gaps.Two groups of control line core conductors adopt glass fiber to strengthen, and S or Z-direction that the insulated wire cores pair twist breaks traditions are stranded, use for reference the stranding technology of optical fiber, adopt the stranded pitch of SZ make the control core more than reach about 0.3% of cable overall length, when cable is subject to tensile impact like this, because of the long buffering of having a surplus, can effectively prevent and avoid the control core fracture of less cross-sectional area of conductor, thereby improved the security reliability of cable, prolonged useful life.In addition, adopt the wrapped formation screen of tightening of two-sided semi-conductive rubber strap during control core pair twist, can anti-electromagnetic interference.
4, fiber unit design
The fiber unit that the utility model arranges adopts high-strength, fatigue-resistant optical fiber, guarantees that fiber unit is in reliability and the life-span of the abominable service condition in down-hole.The optical fiber SZ of fine pith is stranded and aramid fiber fortifying fibre single-screw is stranded, guarantees that fiber unit has larger elongation strain window.The outer bedding and clothing flame retardant type high strength of fiber unit, high-toughness polyurethane (PU) elastic body jacket, oxygen index is high, good flame resistance, tear-proof, anti-extrusion, wear-resisting, low temperature flexibility is good, and elasticity is strong, and stress buffer is good.
