Abstract
A special-purpose U-shaped exposed and laid anti-compression electric cable for a mine is disclosed and specifically relates to the mine electric cable technology field. The special-purpose U-shaped exposed and laid anti-compression electric cable for a mine comprises an elastic outer protection layer (1), a shielding layer (2), an elastic buffer layer (3), an inner protection layer (4), and an electric cable core (5), wherein the shielding layer (2) is arranged at an inner side of the elastic outer protection layer (1), the elastic buffer layer (3) is arranged at an inner side of the shielding layer (2), the inner protection layer (4) is arranged at an inner side of the elastic buffer layer (3), and the electric cable core (5) is arranged at an inner side of the inner protection layer (4). The special-purpose U-shaped exposed and laid anti-compression electric cable for a mine is simple in structure, an inverted shaped design is adopted for the outer protection layer, two support arms of the outer protection layer separate under pressure effects, and therefore pressure can be alleviated.
Description
Technical field:
The utility model relates to mine cable technical field, is specifically related to the special-purpose U-shaped exposed laying resistance to compression cable of a kind of mine.
Background technology:
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
Since the particularity of Minepit environment, the mine fail safe of cable, and crushing resistance is particularly important.Because environment special, in mine, can not carry out buriedly to cable, generally all be to hang in tunnel portion of group or be tiled in ground, through the extruding of equipment, artificial tramples, and cable breaks easily, causes potential safety hazard.
Summary of the invention:
The purpose of this utility model provides the special-purpose U-shaped exposed laying resistance to compression cable of a kind of mine, and it is simple in structure, and outer jacket adopts inverted U-shaped design, has stronger anti-pressure ability, can directly hang in tunnel portion of group or be tiled in ground, two support arms are separately released the pressure under pressure.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises elasticity outer jacket 1, screen 2, elastic cord breaker 3, sheath 4, cable core 5, elasticity outer jacket 1 inboard is provided with screen 2, screen 2 inboards are provided with elastic cord breaker 3, elastic cord breaker 3 inboards are provided with sheath 4, and sheath 4 inboards are provided with cable core 5.
Described outer jacket adopts inverted U-shaped design, becomes flat under pressure, releases the pressure, and becomes original shape again after pressure removes.
Described elastic cord breaker 3 is excessive at pressure, when the U-shaped outer jacket can not support, certain mitigation is arranged.
The utlity model has following beneficial effect: it is simple in structure, and outer jacket adopts inverted U-shaped design, has stronger anti-pressure ability, can directly hang in tunnel portion of group or is tiled in ground, and two support arms are separately released the pressure under pressure.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pressurized flat structure schematic diagram.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises elasticity outer jacket 1, screen 2, elastic cord breaker 3, sheath 4, cable core 5, elasticity outer jacket 1 inboard is provided with screen 2, screen 2 inboards are provided with elastic cord breaker 3, elastic cord breaker 3 inboards are provided with sheath 4, and sheath 4 inboards are provided with cable core 5.
Described outer jacket adopts inverted U-shaped design, becomes flat under pressure, releases the pressure, and becomes original shape again after pressure removes.
Described elastic cord breaker 3 is excessive at pressure, when the U-shaped outer jacket must support, certain mitigation is arranged.
This embodiment has following beneficial effect: it is simple in structure, and outer jacket adopts inverted U-shaped design, has stronger anti-pressure ability, can directly hang in tunnel portion of group or is tiled in ground, and two support arms are separately released the pressure under pressure.
