Abstract
The invention relates to a metallic shield rubber jacketed flexible cable used for a shuttle car in an underground coal mine. The metallic shield rubber jacketed flexible cable used for the shuttle car in the underground coal mine comprises an outer protective cover, three power line cores, two bare land wires, a pilot wire and a fiber bundle reinforcing core, and the three power line cores, the two bare land wires, the pilot wire and the fiber bundle reinforcing core are arranged in the outer protective cover. Each power line core is composed of a power line core conductor, a power line core insulating layer which is covered on the outer portion of the power line core conductor and a shielding layer which is covered on the outer portion of the power line core insulating layer. The pilot wire is composed of a pilot wire conductor and a pilot wire insulating layer which is covered on the outer portion of the pilot wire conductor. The three power line cores are distributed into a triangle shape. The fiber bundle reinforcing core is filled into the central gap of the three power line cores. The two bare land wires and the pilot wire are respectively arranged in the outer edge gaps of the two adjacent power line cores of the three power line cores. Due to the fact that the fiber bundle reinforcing core is filled into a cable, the metallic shield rubber jacketed flexible cable used for the shuttle car in the underground coal mine improves softness of the cable, improves tensile strength of the cable and reduces wire break ratio.
Description
Technical field
The present invention relates to a kind of metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars, belong to technical field of electric wires and cables.
Background technology
Colliery underground shuttle car cable is the connecting line for shuttle car transmission power and signal, and its end connects shuttle car equipment, and the other end connects power supply.Because environment for use is abominable, the useful life of cable is very short, and the fault that the most often occurs is exactly disconnected core, and the cable of the disconnected core of appearance all can't be repaired at the scene basically.Common way is changed cable exactly, and it is substantially all to complete in narrow tunnel that cable more changes jobs, and almost complete in manually completing, work difficulty is large.
Summary of the invention
In order to overcome the easily deficiency of disconnected core of existing metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars, the invention provides a kind of metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars.
the technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars, described cable comprises oversheath and is placed in three interior power cores of described protective jacket, two bare area lines, pilot wire and fibre bundle strengthening core, described power core is by the power line core conductor, the screen that is coated on the power line core insulation layer of described power line core conductor outside and is coated on described power line core insulation layer outside consists of, described pilot wire is to be made of pilot wire conductor and the pilot wire insulating barrier that is coated on described pilot wire conductor outside, described three power cores are triangular shape and arrange, described fibre bundle strengthening core is filled in the center edge gap of described three power cores, described two described bare area lines and a described pilot wire are separately positioned in limit, the outside gap of adjacent two power cores in described three power cores.
Further, all be provided with the strengthening core of being made by synthetic fiber bundle in described power line core conductor, bare area line and pilot wire conductor.
Further, all to adopt ethylene-propylene rubber be that the insulation compound of base-material is made for described power line core insulation layer and pilot wire insulating barrier.
Further, the outer screen of described power core adopts semiconductive to extrude or the semi-conductive tape covering.
Further, be provided with the specialty synthetic fibre silk in described oversheath.
Further, described fibre bundle strengthening core is to adopt the stranded bunchy of specialty synthetic fibre.
The invention has the beneficial effects as follows, metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars of the present invention pass through fiberfill fibers bundle strengthening core in cable, to improve its flexibility, improved the tensile strength of cable, reduce outage.
Description of drawings
Fig. 1 is the structural representation of metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars of the present invention.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example only is used for explaining the present invention, is not be used to limiting scope of the present invention.
as shown in Figure 1, a kind of metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars, it comprises oversheath 8 and is placed in three interior power cores of protective jacket 8, two bare area lines 4, pilot wire and fibre bundle strengthening core 5, the power core is by power line core conductor 1, the screen 3 that is coated on the power line core insulation layer 2 of power line core conductor 1 outside and is coated on power line core insulation layer 2 outside consists of, pilot wire is to be made of pilot wire conductor 6 and the pilot wire insulating barrier 7 that is coated on pilot wire conductor 6 outsides, three power cores are triangular shape and arrange, fibre bundle strengthening core 5 is filled with in the center edge gap of three power cores, two bare area lines 4 and a pilot wire are separately positioned in limit, the outside gap of adjacent two power cores in three power cores.All added the strengthening core of being made by synthetic fiber bundle in power line core conductor 1, bare area line 4 and pilot wire conductor.It is that the insulation compound of base-material is made that power line core insulation layer 2 and pilot wire insulating barrier all adopt ethylene-propylene rubber.The outer screen 3 of power core adopts semiconductive to extrude or the semi-conductive tape covering.Be provided with the specialty synthetic fibre silk in oversheath 8.Fibre bundle strengthening core 5 is to adopt the stranded bunchy of specialty synthetic fibre.
Metal-shielded rubber-sheathed flexible cable for underground coalmine shuttle cars of the present invention pass through fiberfill fibers bundle strengthening core in cable, to improve its flexibility, improved the tensile strength of cable, reduce outage.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
