In figure: 1-insulate silica gel heat dissipating layer, 2-detent projection, 3-heat-radiation belt, 4-steel wire woven armored layer, 5-is outer the most wrapped Layer, 6-screen layer, lapping layer in 7-, 8-padded coaming, 9-inner sheath, 10-inner shield set, 11-insulating barrier, 12-conductor, 13- Inner core frame.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.

Refer to Fig. 1, a kind of spline-simulating high intensity Underground Mine line cord, including: inner core frame 13, three of the wires, around Covering 7, the screen layer 6 being coated on outside interior lapping layer 7 and the outer lapping layer 5 being coated on outside screen layer 6, depend on outside lapping layer 5 outside Secondary it is provided with steel wire woven armored layer 4, insulation silica gel heat dissipating layer 1 and heat-radiation belt 3；Inner core frame 13 is made up of elastomeric material, inner core Frame 13 is axial arranged along cable, and inner core frame 13 includes three the first elastic plates and three the second elastic plates, three the first elastic plates One end be connected the other end and three the second elastic plates are vertically connected one by one near the side of the first elastic plate, each first is elastic The structure that second elastic plate of plate and corresponding connection collectively forms has the cross section of T-type structure, wherein, three the first bullets Property plate is circularly and evenly distributed, it is ensured that the intensity of cable all directions is identical.

Three of the wires is circumferentially distributed around inner core frame 13, and each wire is resisted against one by one near inner core frame 13 side Second elastic plate is resisted against on the inner surface of interior lapping layer 7 away from the side of the first elastic plate, the side away from inner core frame 13, institute State insulating barrier 11 that each wire includes conductor 12 the most successively, is coated on outside conductor 12, be coated on outside insulating barrier 11 Inner shield set 10, the inner sheath 9 being coated on outside inner shield set 10, wherein, conductor 12 is formed by many copper wires are stranded, improves electricity The tensile strength of cable.

Being filled with padded coaming 8 in gap between described three of the wires and interior lapping layer 7, padded coaming 8 is polypropylene Foam plastics, the setting of padded coaming 8, when cable is bent, the padded coaming 8 of polypropylene foam becomes prior to cable Shape alleviates the wire frictional force by the external world, avoids the friction between three of the wires simultaneously, thus reduces wire abrasion broken string Risk, improve the security performance of cable.Steel wire woven armored layer 4 is coated with heat-conducting layer, is extruded with insulation outside heat-conducting layer Silica gel heat dissipating layer 1, wraps up some heat-radiation belts 3, if the spiral back side of heat-radiation belt 3 is provided with outside insulation silica gel heat dissipating layer 1 Dry detent projection 2, detent projection 2 is equivalent to positive stop strip, can also improve optical cable outer layer while playing spacing positioning action Area of dissipation, is effectively diffused into the heat that cable produces in air, for the cable of multi-thread parallel layout, owing to cable is mutual Between detent projection serve good spacing fixation, the situation effectively preventing twisted wire and swinging cross to be wound around occurs, for wiring Provide convenience.

In the present embodiment, each first elastic plate of inner core frame 13 and the second common structure of elastic plate of corresponding connection The structure become has the cross section of T-type structure, make use of the feature that the bending strength of T-type structure is big, improves the bending resistance of cable Intensity, additionally the second elastic plate of inner core frame 13 is resisted against outside wire away from the side of the first elastic plate, then coordinates fender Material 8 extrude, can keep the stability of position of wire when cable is bent, the padded coaming of polypropylene foam 8 alleviate the wire frictional force by the external world prior to distortion of the cable, avoid the friction between three of the wires simultaneously, thus reduce The risk of wire abrasion broken string, improves the security performance of cable.

This utility model can not only improve the bending strength of cable, moreover it is possible to improves the overall mechanical properties of cable；Cable The detent projection of outer layer is equivalent to positive stop strip, can also improve the radiating surface of optical cable outer layer while playing spacing positioning action Long-pending, effectively the heat that cable produces is diffused in air, for the cable of multi-thread parallel layout, due to the tooth that cable is mutual Shape projection serves good spacing fixation, and the situation effectively preventing twisted wire and swinging cross to be wound around occurs, and provides for wiring Convenient.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment party Formula, in the ken that one skilled in the relevant art is possessed, it is also possible on the premise of without departing from this patent objective Various changes can be made.
