Description

High-tensile wear-resistant scraper cable and production process
Technical Field
The invention relates to the technical field of alloy cables.
Background
Because the use condition of scraper cable is very complicated and abominable, sharp ore and dregs challenge its wearability to bear great tensile force when often curling and stretching, also always be in high load, overload operation, often cause broken core, the short circuit of cable, the conductor generates heat and causes insulating layer damage, spiral deformation, the damage of sliding sleeve, and then cause cable life weak point, use cost is high.
There is a need for a cable and a production process that solves the above problems.
Disclosure of Invention
The invention aims to solve the technical problem of providing a high-tensile wear-resistant scraper cable and a production process, wherein the cable has high tensile capacity, is super-wear-resistant, cracking-resistant, oil-resistant, high-flexibility, pressure-resistant, bending-resistant, ultraviolet-resistant, weak acid-alkali-resistant and high-low temperature-resistant.
In order to solve the problems, the technical scheme adopted by the invention is that the high-tensile wear-resistant scraper cable sequentially comprises a core wire, an insulating layer, an inner sheath, a reinforcing piece and an outer sheath from inside to outside, wherein the core wire is made of annealed oxygen-free copper ultrafine wires with the purity of 99.99%, the insulating layer is made of ethylene propylene diene monomer, the inner sheath and the outer sheath are made of polyurethane or high-strength synthetic rubber, and the reinforcing piece is arranged between the inner sheath and the outer sheath.
Preferably, the core wire comprises a power core wire and a ground core wire.
Preferably, the core wire is made of copper or aluminum alloy.
The reinforcement comprises a first layer of braiding and a second layer of braiding, wherein the first layer of braiding and the second layer of braiding are both fiber ropes, and the first layer of braiding and the second layer of braiding form a grid structure and are arranged between the inner sheath and the outer sheath.
Preferably, the fiber rope is a polyurethane rope or an aramid rope.
Preferably, 1) a core wire is manufactured; 2) Insulating treatment; 3) Carrying out matched treatment and knitting reinforcement; 4) Wrapping water for washing cloth or extruding PP; 5) Vulcanizing in a vulcanizing tank; 6) Removing the water washing cloth or PP; 7) Carrying out factory inspection on finished products; 8) Packaging and warehousing.
Preferably, the core wire in the step 1) comprises a power core wire and a ground wire core, and the power core wire in the step 2) is subjected to spark test after being subjected to insulation treatment.
The cable has the advantages of high tensile capacity, super wear resistance, cracking resistance, oil resistance, high flexibility, pressure resistance, bending resistance, ultraviolet resistance, weak acid and alkali resistance and high and low temperature resistance.
