Description
Technical field:
The utility model relates to technical field of electric equipment, particularly a kind of Compression-resistincable cable.
Background technology:
At present, the structure of cable is exactly roughly inner many main lines, outer wrap overcoat, certain main line also distinguishes respective outer coated sheath, but in reality, all conveyer can be used in some sandpits and coal yard, and power line is all portable, unavoidably often have large-scale excavator, bull-dozer goes and back running, normal cable all cannot stand and repeatedly rolls, the damage turnover rate of cable is very high, causes great waste.So the common cable of current this circle is rolled, its insulated hull breakage rear forms phase fault, electric power damages, and the cable needing a kind of Anti-pressure badly solves this problem.China Patent No.: 201210537464.7 patent discloses a kind of Compression-resistincable cable, comprise three boundlings cable main line together, overall arranged outside cable cover(ing) after boundling; Three cable main line boundling modes adopt structure in one line and are all in same level, and do not extrude mutually in the vertical direction, cable cover(ing) cross section is flat or oval structure.Cable main line adopts braiding structure.All wrap up independent insulating coating outside described every root cable main line, this insulating coating adopts ethylene-propylene rubber to make.But this patented technology exists manufacturing cost costliness, complex structure, compressive resistance ability is more weak, and useful life is shorter in actual use.In addition, cable in use causes heating, has risk of igniting.For solving this technical problem, need to occur that a kind of structure is simple, easy to use, the high and long service life of intensity, resistance to compression is effective and have a kind of Compression-resistincable cable of cooling-down effect.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming existed in prior art, provides a kind of structure simple, easy to use, the high and long service life of intensity, and resistance to compression is effective and have a kind of Compression-resistincable cable of cooling-down effect.
To achieve these goals, the utility model provides a kind of Compression-resistincable cable, comprise outer sebific duct, inner sleeve, cable, back-up block and ventilation duct, wherein, described inner sleeve cross section is regular hexagon, inner sleeve inner hollow, inner sleeve inside is provided with cable, inner sleeve is three, three inner sleeve arrangements in " product " shape, inner sleeve arranged outside has 12 pieces of back-up blocks, back-up block cross section triangle in obtuse angle, three pieces of back-up blocks are one group and the footing of adjacent two back-up blocks is welded and fixed successively and then constitutes ventilation duct, ventilation duct is four, ventilation duct is centered around the outside of inner sleeve, inner sleeve and back-up block are adhesively fixed, inner sleeve, the outer cover of back-up block is connected to outer sebific duct.
The cross section of ventilation duct is equilateral triangle.
Advantage of the present utility model is, structure is simple, easy to use, the high and long service life of intensity, and resistance to compression is effective and have cooling-down effect.Be specially:
The utility model is first by the arrangement in " product " shape of three inner sleeves, three inner sleeves are welded and fixed, cable is penetrated three inner sleeve inside again, by 12 pieces of back-up blocks, every three pieces is one group, three pieces of back-up block footing are welded and fixed successively, make four ventilation ducts, be arranged in " product " shape inner sleeve both sides, and back-up block outer wall and inner sleeve outer wall are welded and fixed, finally build outer sebific duct at inner sleeve and back-up block outside, inner sleeve and back-up block are wrapped in outer sebific duct.After cable pressurized, the cavity structure of ventilation duct, pressurized deformation, reduces cable pressure, and after external force disappears, ventilation duct recovers shape, and then plays measuring body effect.In addition, leg-of-mutton ventilation duct has aeration-cooling effect, avoids cable to ignite.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Accompanying drawing identifies:
1, outer sebific duct 2, inner sleeve 3, cable 4, back-up block 5, ventilation duct
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described.Fig. 1 is structural representation of the present utility model.
The utility model Compression-resistincable cable, comprise outer sebific duct 1, inner sleeve 2, cable 3, back-up block 4 and ventilation duct 5, wherein, inner sleeve 2 cross section is regular hexagon, inner sleeve 2 inner hollow, inner sleeve 2 inside is provided with cable 3, inner sleeve 2 is three, three inner sleeve 2 arrangements in " product " shape, inner sleeve 2 arranged outside has 12 pieces of back-up blocks 4, back-up block 4 cross section triangle in obtuse angle, three pieces of back-up blocks 4 are one group and the footing of adjacent two back-up blocks 4 is welded and fixed successively and then constitutes ventilation duct 5, ventilation duct 5 is four, ventilation duct 5 is centered around the outside of inner sleeve 2, inner sleeve 2 and back-up block 4 are adhesively fixed, inner sleeve 2, the outer cover of back-up block 4 is connected to outer sebific duct 1.The cross section of ventilation duct 2 is equilateral triangle.
The utility model structure is simple, easy to use, the high and long service life of intensity, and resistance to compression is effective and have cooling-down effect.The utility model is first by the arrangement in " product " shape of three inner sleeves, three inner sleeves are welded and fixed, cable is penetrated three inner sleeve inside again, by 12 pieces of back-up blocks, every three pieces is one group, three pieces of back-up block footing are welded and fixed successively, make four ventilation ducts, be arranged in " product " shape inner sleeve both sides, and back-up block outer wall and inner sleeve outer wall are welded and fixed, finally build outer sebific duct at inner sleeve and back-up block outside, inner sleeve and back-up block are wrapped in outer sebific duct.After cable pressurized, the cavity structure of ventilation duct, pressurized deformation, reduces cable pressure, and after external force disappears, ventilation duct recovers shape, and then plays measuring body effect.In addition, leg-of-mutton ventilation duct has aeration-cooling effect, avoids cable to ignite.
