Movable anti-aging cable for stacker-reclaimer

Abstract

The invention discloses a movable anti-aging cable for a stacker-reclaimer. The movable anti-aging cable comprises a fixation tough pipe, a tin cladding layer, a flame-retardant layer, a tensile layerand an oxygen barrier layer. The fixation tough pipe comprises a hollow pipe and a rubber pressing block. The fixation tough pipe is arranged in the tin cladding layer and fixedly connected with theouter surfaces of conductor bodies in a clamped mode; a cavity channel is formed in the middle of a hollow pipe; and the outer surface of the hollow pipe is fixedly connected with the rubber pressingblock perpendicularly. The fixation tough pipe and the conductor bodies form an integrated structure with deformation resistance, so that the overall pressure resistance is enhanced; and the separatedintegrated fixation mode can reduce the material torsion and stretching conditions caused by different deformation amounts due to the internal and external deformation offset of each layer of the cable caused by working movement. Besides, through the control of the tin cladding layer on the internal temperature, the strong flame-retardant property of the flame-retardant layer, the good torsion resistance of the tensile layer, and the thermal aging resistance of the oxygen barrier layer, the aging resistance of the whole cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a stacker-reclaimer mobile anti-aging cable. Background technique [0002] Bucket wheel stacker and reclaimer (stacker and reclaimer) is a new type of high-efficiency continuous loading and unloading machine, mainly used for loading and unloading iron in bulk storage yards such as professional bulk cargo terminals, steel plants, large thermal power plants, and mines. Ore (sand), coal, sand, etc. The cable is usually a rope-like cable twisted by several or several groups of wires, each of which is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a high degree of insulation. overlay. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cabl...

AI Technical Summary

Problems solved by technology

[0003] The stacker-reclaimer needs to use a large number of cables to provide power transmission, and most of these cables have the characteristics of relative movement when working with the equipment. If things go on like this, the working cycle will easily cause fatigue and wear of the cables and the open-air working environment. Aggravate the aging phenomenon of cables

The traditional cables used on the stacker-reclaimer have such problems for a long time, resulting in a decrease in the service life of the cables, a large safety hazard, and an increase in the economic cost of maintenance
