Thermotropic fluorescence coal mining machine cable

Abstract

The invention discloses a thermotropic fluorescence coal mining machine cable, and the cable comprises a cable core, an aramid yarn braided layer, an outer sheath and an outer sheath; the aramid yarnbraided layer, the outer sheath and the outer sheath wrap the cable core from inside to outside, and the cable core is formed by twisting a plurality of insulated wires and control wire cores; each insulating wire core comprises a conductor and an insulating layer wrapping the conductor, each control wire core is formed by twisting a middle pad and a plurality of control wires, each control wire comprises an aramid fiber wire bundle, an inner rubber layer, a wire layer and outer rubber which are arranged from inside to outside, and each wire layer is formed by winding a control wire. Accordingto the thermotropic fluorescence coal mining machine cable, the conductor structure, the insulating braid layer, the control line structure and the outer sheath are improved, so that the cable has the characteristics of long service life, thermotropic fluorescence, bending resistance, high strength and impact resistance, and is very suitable for coal mining working conditions.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a thermoluminescent coal shearer cable. Background technique [0002] The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. As a kind of power and signal transmission equipment, the shearer cable has harsh working conditions. During use, it will be smashed by gangue and coal blocks, as well as scraped and squeezed by various machinery. It needs to be bent frequently, the core of the control line is easy to break, and it is difficult to identify in the dim light in the mine, while the traditional fluorescent cable needs strong light to excite the electrons to emit light for a short time, and the light continues, causing light pollution in the dark environment.
