The power wire cores, three cores of which are increased in a uniform cross section way within the allowed scope of a diameter; and the monitoring cable core with properly reduced cross section are arranged on an outer edge gap of the cable core in a filling way, two nude auxiliary ground wires are respectively added on other two edge gaps of the cable core, and a middle gap of the c able core is filled with semi-conductive saturated filling. In the flexible cable, power transmission and signal control are integrated, the anti-interference capability is strong and the signal transmission is stable; the symmetrical structure stranding method is adopted, the cable external diameter can be effectively reduced, the cable stability can be enhanced, the special requirement of complicated, long and periodical movement of an underground shuttle car can be satisfied, and the cable can be widely applied in machine tool tow chain systems, field mobile equipment and coiling equipment.
Description
Technical field:
The utility model relates to a kind of down-hole shuttle car with warping strength high flexibility shielded flexible cable, belongs to the cable technology field.
Background technology:
Coal is the main energy sources of China, and is closely related with economic construction and people's daily life.For guaranteeing energy resource supply, keep the high speed development of economic construction, the yield of coal in China increases with the speed more than 8% every year fast.Mining cable is the indispensable auxiliary products of coal industry, is called " blood vessel " and " nerve " of coal industry.Along with the continuous progress of mining technique, the colliery increases sharply with the demand of cable special purpose and high performance index, and especially the down-hole shuttle car is exactly one of them with the metallic shield flexible cable.
The down-hole shuttle car connects shuttle car equipment with cable one end, and an end connects power supply.In use, be in and reeled---stretching---again reel---all the time under the stretching again cycle movement state along with the motion of shuttle car.Yet underworkings is very narrow, and cable has by the borehole wall or supporting thing at any time hangs the possibility of hindering; Receive the restriction of cable hoist capacity and shuttle car range ability in addition, the overall dimension of cable also must have strict restriction.
The utility model content:
The utility model design to metallic shield flexible cable under the existing well be prone to broken string, wiring is complicated, signal attenuation is strong, antijamming capability is weak, the narrow and small lane space utilance in down-hole is low, is that the down-hole shuttle car of one is with warping strength high flexibility shielded flexible cable and develop a kind of power transmission and signal controlling gathered.This product has improved the cable utilance, has made things convenient for project installation, can also extensively apply to installing and using of lathe drag chain system, open-air mobile device, reel equipment.
Technical scheme below the utility model design is adopted: the utility model comprises the oversheath that cable core is outer with being arranged on cable core; Said cable core is by being symmetricly set on three inner power cores of cable; Be arranged on a supervision core, two auxiliary ground wires compositions in gap, the power core outside in twos, the saturated filling of semiconductive is adopted in the gap at cable core center.
Said power core, pilot wire core conductor are by synthetic fibers and annealed copper wire or tin annealed copper wire is stranded in the same way forms; The stranded conductor center is provided with the specialty synthetic fibre reinforcement; Stranded conductor peripheral hardware novel elastic irradiated polymer rubber-covered, the metal knitted shielding of insulation peripheral hardware.
Said auxiliary ground wire takes soft junction structure conductor to extrude wearable environment protection flexible polyurethane insulating barrier outward.
Described oversheath adopts the environment protection high flame resistance polyolefin.
The cable of the utility model increases by three core uiform section power line core conductor cross sections in the cable in the diameter allowed band; The supervision core cross section that suitably dwindles is placed in the crack, cable core outside with filling mode; And in the crack, two outsides in addition of cable core, respectively increasing an auxiliary ground core, the cable core center clearance adopts semiconductive to fill saturated filling.The stranded employing of stranding 3+3 symmetric mode guarantees that the construction of cable is stable, strengthens the ability of anti-extraneous mechanical stress simultaneously greatly.This new product cable has that high-low temperature resistant, good insulation preformance, travelling performance are strong, good bending property, anti-bending radius are little, wear-resisting; Superior characteristic such as Stability Analysis of Structures; Can deal with the operational environment under the mal-condition; Can be for the operation of the long-term security of down-hole shuttle car provide safeguard, can also extensively apply to installing and using of lathe drag chain system, open-air mobile device, reel equipment simultaneously.
The utility model project organization is rationally simple, and the cable utilance is high, and wiring is convenient, manufactures easily; Cost is low, and cable smooth in appearance rounding has anti-bending; Wear-resisting, have the environment protection high flame resistance characteristic, can guarantee the long-time safe operation of equipment such as down-hole shuttle car.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, power core; 2, power line core insulation; 3, metal knitted shielding; 4, auxiliary ground wire; 5, the saturated filling of semiconductive; 6, pilot wire core conductor; 7, pilot wire core insulation; 8, keep watch on the core shielding; 9, specialty synthetic fibre reinforcement; 10, oversheath.
Embodiment
The utility model comprises that three core power cores 1, one keep watch on core, two auxiliary ground wires 4, adopts the stranded formation cable core of 3+3 symmetry, and the cable core center clearance adopts the saturated filling 5 of semiconductive, and cable core squeezes oversheath 10 outward.The cable core process route of new product is employed in the power core 1 that three core uiform sections increase in the diameter allowed band; Suitably the supervision core of reduced cross-sectional is placed in the crack, cable core outside with the mode of filling; And in two other crack, limit of cable core, respectively increasing an auxiliary ground wire 4, the cable core center clearance adopts the saturated filling 5 of semiconductive.Stranding adopts the stranded mode of 3+3 symmetrical structure, when effectively reducing the outside diameter of cable, also can improve the stability of cable, prolongs cable useful life significantly.This new product conductor adopts stranded in the same way, has reduced the external diameter of cable, and the stranded conductor central strand is placed specialty synthetic fibre reinforcement 9; Improve the anti-Zhang Nengli of cable conductor itself greatly, what when cable is stressed, be stretched at first must be the specialty synthetic fibre of state linearly, along with the increase of external force; Elongation strengthens; Spiral copper conductor just is stretched, and so effective minimizing conductor receives extraneous mechanical stress, increases the useful life of cable.
Described power line core conductor, supervision core are adopted conductor 6 usefulness flexible conductors or tin annealed copper wire and specialty synthetic fibre reinforcement 9 strands, and specialty synthetic fibre reinforcement 9 is arranged on the center, and conductive surface should not have greasy dirt, the most advanced and sophisticated projection of smooth nothing; Power line core insulation 2, pilot wire core insulation 7 adopt novel elastic irradiated polymer rubber, allow the long-time running temperature can reach 180 °.
Phase-splitting shielding core is taked in the metal knitted shielding 3 of said power line core insulation 1 peripheral hardware, but metal knitted shielding double as earth connection; Pilot wire core insulation 7 peripheral hardwares are kept watch on core shielding 8, have the transmission of control or monitor signal.
Said auxiliary ground wire 4 takes soft junction structure conductor to extrude the flexible polyurethane insulating layer of wearable environment protection.
The oversheath 10 of said cable is the environment protection high flame resistance polyolefine material.
