Abstract
The invention discloses a moisture-proof and compressive cable for machines in coal yards, comprising at least three aluminum alloy wires and insulating layers arranged outside the aluminum alloy wires. The aluminum alloy wires are spirally wound on an aramid yarn centerline. A metal ring layer is arranged outside the aluminum alloy wires. A rubber cushion layer is arranged inside the metal ring layer. The inner wall of the rubber cushion layer is provided with spirally-distributed grooves. The outer walls of the insulating layers fit the inner sides of the grooves. An outer insulating layer is arranged outside the metal ring layer. The outer wall of the rubber cushion layer is provided with spirally-distributed depression structures which are filled with sponge, and the spiral direction of the depression structures is opposite to the spiral direction of the grooves. By adopting the rubber cushion layer with a sponge layer, an effect of moisture absorption is achieved, and the cable is protected from moisture.

Reference numeral: 101. aluminium alloy conductors, 102. insulating barriers, 103. aramid fiber yarn center lines, 104. metal ring layers, 105. rubber spacers, 106. outer insulations, 107. sunk structures, 108. bamboo-carbon layers, 109. antioxidation coatings.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, the moistureproof Compression-resistincable cable of a kind of coal yard machinery, comprise at least 3 aluminium alloy conductors 101 and be arranged on the insulating barrier 102 of aluminium alloy conductor 101 outside, described aluminium alloy conductor 101 is helically wrapped on aramid fiber yarn center line 103, metal ring layer 104 is had in described aluminium alloy conductor 101 outer setting, described metal ring layer 104 inside is provided with rubber spacer 105, described rubber spacer 105 inwall is provided with the groove of arranging in the shape of a spiral, described insulating barrier 102 outer wall is fitted in inside described groove, outer insulation 106 is had in described metal ring layer 104 outer setting, described rubber spacer 105 outer wall is provided with the sunk structure 107 of helically direction arrangement, sponge is filled with in described sunk structure 107 inside, the hand of spiral of described sunk structure 107 is contrary with the hand of spiral of described groove.
When the present invention is subject to external compression, owing to being provided with metal ring layer, the effect of protection aluminium alloy conductor can be played; Because middle part is provided with aramid fiber yarn center line, aluminium alloy conductor can be made to be wrapped on aramid fiber yarn center line, make aluminium alloy conductor resistance to compression and tensile strength larger, be not easy impaired, meanwhile, be arranged on the sponge in sunk structure, the effect absorbing outside moisture can be played, avoid moisture to enter aluminium alloy conductor inside, avoid short circuit phenomenon.Adopt the setting that groove direction is contrary with aluminium alloy conductor direction in the present embodiment, integrally-built tensile property can be increased, improve integrally-built intensity.
Embodiment 2:
In order to improve integrally-built humidity resistance, in the present embodiment, on the basis of embodiment 1, preferably, in described metal ring layer 104 outer cover, bamboo-carbon layer 108 is housed.By adopting bamboo-carbon layer, can outside moisture be adsorbed, because bamboo charcoal has reversible hygroscopic effect, after used a period of time, by the mode of airing, the moisture evaporation on the bamboo charcoal of corresponding site can be made.
In the present embodiment, preferably, described metal ring layer 104 is that sheet metal bar is helically wrapped on described rubber spacer 105 outer wall.By adopting spiral canoe, the production of metal ring layer can being facilitated, meanwhile, by mutually covering the mode be wound around, the intensity of metal ring layer can be strengthened.
In order to improve the stretch-proof performance of cable, in the present embodiment, preferably, the spiral winding direction of described metal ring layer 104 is contrary with the hand of spiral of described sunk structure 107.By adopting reverse spiral winding mode, cable can be made when being subject to stretching, and metal ring layer and sunk structure produce reverse active force, thus metal ring layer can be avoided to be stretched distortion, contribute to the intensity improving metal ring layer.
Because open space electric power cable easily produces aging under light illumination, cause cable easily to damage, in the present embodiment, on the basis of embodiment 1, preferably, have antioxidation coating 109 in described outer insulation 106 outer setting.
