Photoelectric control composite cable for mining machine

Abstract

The invention discloses a photoelectric control composite cable for a mining machine. The photoelectric control composite cable comprises an optical control wire core, a power wire core and a ground wire core; the optical control wire core comprises an optical cable, a plurality of control wire cores and an isolation belt; the plurality of control wire cores are snapped to the optical cable; the isolation belt wraps the optical cable and the control wire cores; every control wire core comprises a first conductor and a first insulation layer; the power wire core comprises a second conductor; a second insulation layer and an insulation shielding layer wrap the second conductor; the ground wire core comprises a third conductor and a semi-conducting layer; filler is arranged in an arrangement gap of the optical control wire core and the power wire core to form a cable core; a wrapping belt layer, an inner sheath layer, a fiber reinforcement layer and an outer sheath layer wrap the cable core. According to the photoelectric control composite cable for the mining machine, the signal collection and electrical control performance is excellent, the safety, the reliability and the durability are high, the integrated photoelectric control composite structure is simple, the transmission performance is stable, and the photoelectric control composite cable can be widely applied to integrated signal and control and power signal composite transmission of mining spaces such as coal, mining and tunnel excavation.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a photoelectric control composite cable for mining machines. Background technique [0002] At present, in my country's coal and mine mining, tunnel excavation and other mining sites, the cables used for mining machines are generally used for ordinary shearer flexible cables and shield machine cables. However, the following problems have been exposed during use: [0003] 1. The control core, the power core and the ground core are easy to break, and the service life is short, and its safety and reliability are low, and the economy is poor. [0004] 2. It does not have the transmission function of photoelectric signals, and corresponding communication signal cables need to be laid and installed separately. At the same time, its laying conditions and use channels require special devices, which are high in cost and scattered in structure. Contents of the invention [0005] The purpo...
