Reinforcement layer and wearing layer one-step molding metal shielding mobile rubber jacketed flexible cable

Abstract

The present invention discloses a reinforcement layer and wearing layer one-step molding metal shielding mobile rubber jacketed flexible cable, belonging to the field of wire and cable manufacturing.The cable comprises a wearing layer, a reinforcement layer, a metal total shielding layer, an outer cable core and an inner cable core. The wearing layer comprises an outer layer of a wear-resisting sheath layer and an inner layer of a wear-resisting sheath layer, and the reinforcement layer is a mesh braiding layer inlaid between the outer layer of the wear-resisting sheath layer and the inner layer of the wear-resisting sheath layer. The defects are solved that a traditional cable conductor used for a rubbish derrick and a similar device is frequently moved and bent, easy to generate fracture of the conductor after being pulled, is not wear-resistant in the cable sheath, poor in crushing-resistant performance and poor in cable anti-interference performance and inhibition capacity of interference. The cable provided by the invention is good in high-strength tensile, wear-resistant, torsion-resistant, bend-resistant, oil-resistant, ultraviolet-proof, acid and alkali resistant, anti-corrosion, waterproof and not easy to break off the core wire and is not layered in the sheath.

Description

technical field [0001] The invention relates to a metal-shielded mobile rubber-sheathed flexible cable with a reinforced layer and a wear-resistant layer formed at one time, belonging to the field of electric wire and cable manufacturing. Background technique [0002] The garbage grab crane is the core equipment of the feeding system of the garbage incineration plant. It is mainly responsible for the feeding of the hopper of the garbage incinerator and the handling, mixing, stacking, and stacking of garbage in the pit. Its working status plays a key role in the normal operation of the entire waste incineration plant. Once the garbage grab crane breaks down, which affects the feeding of the garbage incinerator, it will directly paralyze the entire garbage incineration plant. [0003] Because the garbage grab crane works in a dusty, high temperature, high humidity and highly corrosive gas environment, the grab cable and electric control cabinet are generally not installed on ...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide a metal shielding mobile rubber-sheathed flexible cable with a reinforced layer and a wear-resistant layer at one time, which adopts a continuous non-stop one-time molding production process technology, that is, three-step one-time molding technology, first extruding with a rubber machine The inner sheath is taken out, and then the reinforcing layer is braided by a horizontal 24-spindle braiding machine, and then the outer sheath is extruded by a rubber extruder, and finally vulcanized through a vulcanization pipeline. Through continuous production of three processes, the inner sheath is completed at one time Extrusion, reinforcing layer braiding and outer sheath extrusion realize the one-time vulcanization of the cable sheath, and solve the problem of stains, stains, etc. The oil stains generated when weaving fibers, the pollution on the surface of the inner sheath during the process of process flow, and the outer sheath layer when processing the outer wear-resistant sheath layer, due to the dense layer formed on the inner sheath layer and the fully vulcanized surface, the outer sheath layer is squeezed The air covered in the wrapping process cannot pass through the inner sheath layer and be removed along the cable core, which avoids the phenomenon that the cable sheath expands and generates bubbles when it passes through the steam vulcanization pipeline, and solves the problem that the cable sheath After water cooling, the serious quality defect of bursting caused by the imbalance of internal and external pressure also simplifies the processing procedure and avoids the insulation damage caused by the large extrusion force during the secondary vulcanization extrusion of the sheath in the traditional processing technology. Deformation of the wire core, "eccentricity" of the insulation layer, and the reduction of the electrical insulation performance of the cable solve the problem of frequent movement and bending of the cable conductor, easy conductor breakage after dragging, non-wear-resistant cable sheath, and frequent bending of the cable sheath layer and the reinforcement layer Disadvantages such as delamination, poor anti-extrusion performance, weak anti-interference and interference suppression ability of the cable
