Description
Technical field:
The utility model relates to a kind of low-resistance wear-resistance plastic-steel composite cable conduit with quartz sand layer.
Background technology:
Pipe material as plastic cable protection on market has two large classes substantially, and a kind of is thermoset plastics, wherein take GRP pipe as main, and another kind is thermoplastics, take PVC, polyethylene, PA tube as main.The pluses and minuses of the pipeline of these two large types of material are as follows:
The advantage in frp cable protective pipe road: (1) GRP pipe is lightweight, rigidity is high, resistance to compression and anti-settling ability are strong; (2) conductive coefficient is large, especially cable for a long time when underground operation advantage more obvious; (3) heatproof is poor good, and in-40 ℃～-150 ℃ environment, can reach 50 years service life.Frp cable protective pipe road, because the defect of technique own and illegal producer manufacture in a rough and slipshod way, serves as without alkali product with high alkali product, the factor such as adulterate; its quality is uneven; while wearing cable, cannot stand friction, the scuffing of traction steel wire, caused glass fibre delamination, cause glass fibre to be entangled on cable; twine more and more; can not advance, can not retreat, cause wearing cable failure; can not realize the object that safety is worn cable, be faced with the danger being eliminated.
The advantage of the thermoplastic pipes such as PVC, polypropylene, polyethylene is a lot, is applied in cable protection field, and outstanding feature is exactly that electrical insulating property is good, inwall smoother, easy cabling, can not cause the phenomenon of stuck cable to occur.But heat-resisting, cold-resistant have a limitation, be difficult to reach the needs of power industry specification requirement.Thermoplastic tubing is tubing more common on market above, respectively has pluses and minuses, but falls far short apart from the requirement of power industry.
At present, on market, need a kind of heat-resisting, high-strength, lightweight, corrosion resistant, fire-retardant, inner wall smooth and economical and practical cable protection pipe again badly.On market, once there is a kind of advantage of utilizing thermoplastic and thermosets, fiberglass and polypropylene are carried out to the composite cable protection pipe of organic assembling, but, what it was taked just simply makes outer tube by fiberglass, thermoplastic tube is made the way of the direct combination of inner tube, because thermoplastics is a kind of very typical nonpolar crystalline material, surface tension is lower, shrinkage is large, creep-resistant property is poor, product size poor stability, easily produce buckling deformation, be difficult to be attached together with other materials, cause the middle gap that occurs of tubing of two kinds of materials, intensity is low.Even, in the process of trailing cable, inner tube can be given and hauled out, not reach the object of market demands.Afterwards, on market, occurred a kind ofly by clamp-on the method for quartz sand at inner tube outer surface, the tubing of two kinds of unlike materials being combined into an integral body closely, although inner and outer tubes can be connected, but, the inner surface of its inner tube is plane, there is larger friction area, in wearing cable process, the contact area of cable and interior pipe internal surface is large, rubbing surface is large, and the frictional force of generation is large, has increased the power of wearing cable hauling machine, the heat producing during simultaneously cable operation is difficult for distributing, to the life requirements of cable, insulate anti-aging unfavorable.
Utility model content:
The utility model is in order to make up the deficiencies in the prior art, a kind of low-resistance wear-resistance plastic-steel composite cable conduit with quartz sand layer is provided, its reasonable in design, at inner tube outer surface, be provided with quartz sand layer, and then at quartz sand layer, be wound around the glass fiber of impregnated with resin outward, the glass reinforced plastic pipe that glass fiber is wound and inner tube can be combined into as a whole closely, and the frictional force between glass reinforced plastic pipe and inner tube increases greatly, have avoided stressed rear inner and outer pipes separated; At interior pipe internal surface, along inner tube, be axially provided with continuously internal thread groove, the contact area of cable and interior pipe internal surface is little, rubbing surface is little, and the frictional force of generation is little, has reduced the difficulty of wearing cable, cable and inner tube are that spiral salient point supports, concave point hovering, thereby increased the space of ventilation and heat, the dissipation of heat that cable produces is easy, has greatly extended the useful life of cable, the safety that has ensured operation of power networks, has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be:
A kind of low-resistance wear-resistance plastic-steel composite cable conduit with quartz sand layer, comprise inner tube, at interior pipe internal surface, along inner tube, be axially provided with continuously internal thread groove, at inner tube outer surface, be provided with quartz sand layer, in the outside of quartz sand layer, be provided with the glass reinforced plastic pipe that the glass fiber by impregnated with resin is wound.
Described quartz sand layer consists of the quartz sand particle of clamp-oning inner tube extexine, and quartz sand layer is circumferentially coated on inner tube extexine and extends axially to two ends along inner tube.
Described inner tube is a thermoplastic pipes.
The utility model adopts such scheme, reasonable in design, at inner tube outer surface, be provided with quartz sand layer, and then at quartz sand layer, be wound around the glass fiber of impregnated with resin outward, the glass reinforced plastic pipe that glass fiber is wound and inner tube can be combined into as a whole closely, frictional force between glass reinforced plastic pipe and inner tube increases greatly, has avoided stressed rear inner and outer pipes separated; At interior pipe internal surface, along inner tube, be axially provided with continuously internal thread groove, the contact area of cable and interior pipe internal surface is little, rubbing surface is little, the frictional force producing is little, has reduced the difficulty of wearing cable, and cable and inner tube are that spiral salient point supports, concave point hovering, thereby increased the space of ventilation and heat, the dissipation of heat that cable produces is easy, has greatly extended the useful life of cable, has ensured the safety of operation of power networks.
