Abstract
The utility model relates to an improved mining tubular product, which is used for conveying medium for industries such as coal mines and gold mines. The utility model is composed of an inner plastic tube layer, an outer plastic tube layer and a middle metal layer composed of steel wires which are radially wound. The utility model has the advantages of reasonable structure, light weight, good corrosion-resisting performance, strong bearing ability, high safety, good application performance, wide application area, radial winding of the steel wires, convenient manufacture, low cost, small occupying field for operation and convenient operation.
Description
Technical field
The utility model relates to a kind of improved mining pipes, is used for colliery, gold mine industry fed sheet of a media.
Background technique
At present, domestic mining pipes adopts steel pipe and Glass Steel Tube usually, because the mining pipes applied environment is more abominable, general underground in humidity, the steel pipe corrosion phenomena is serious, is generally the working life in 1 year, and weight is big, and transport difficulty is big, has increased working strength of workers; There is the shortcoming of shock resistance difference in Glass Steel Tube, and often because the passage falling rocks collapses the cullet steel pipe, Security is relatively poor.
Summary of the invention
The purpose of this utility model is to provide a kind of improved mining pipes, and is rational in infrastructure, in light weight, corrosion resistance and good, and the bearing strength height, safe and reliable, application performance is good, applied range.
Mining pipes described in the utility model is characterized in that being made of inside and outside plastic pipe layer and middle metal layer, and metal layer is made of winding steel wire radially.
Wherein:
Winding steel wire can be spaced apart, or tight arranged distribution, or winding steel wire is connected to one, constitutes metal steel pipe mesosphere, the situation difference spaced apart of steel wire, and pressure-bearing situation difference, more little at interval, pressure-bearing is big more.Winding steel wire radially can improve the bearing strength of tubing effectively, comprises malleation and negative pressure.
Inside and outside plastic pipe layer can be suitable tubing such as PE pipe, pvc pipe or PP pipe, and internal and external layer can be identical material, also can be different materials, and when internal and external layer adopted identical material, internal and external layer can once be made the while.
Lining is established hot melt adhesive between metal layer and plastic pipe layer, regulates the different heat expansion performance of buffering metal layer and plastic pipe layer, strengthens bulk strength, improves usability.Can take to serve as a contrast the dress mode during making, also can will carry out produced with combination after the coated hot melt adhesive of metal materials again.
The utility model mining pipes adopts the composite structure of plastics and metal; composition metal strengthens tubing intensity; the plastic pipe layer good corrosion resistance; the slippery inner surface of inner plastic satisfies the mobile unobstructed requirement of fed sheet of a media, and plastic outer layer had both been protected complex metal layer; comprise steel wire, reinforcing bar etc.; increase tubing intensity again, can add anti-static agent, fire retardant etc. in the plastic layer, improve application performance.The utility model is rational in infrastructure, and is in light weight, corrosion resistance and good, and bearing capacity is strong, and is safe and reliable, application performance is good, has enlarged application area, suitable colliery, gold mine industry fed sheet of a media, and steel wire radially twines, simple for production, cost is low, and the operation occupied ground is little, easy to operate.
