The invention relates to the technical field of scraping operation of mines, in particular to power supply method and equipment of an electric scraper. A super capacitor-cable double-energy source self-traveling type power supply car is driven beside a grid power supply by a super capacitor to be connected with a cable and driven near the electric scraper by the grid power supply; the electric scraper is connected to a wiring box of the self-traveling type power supply car by the cable; a position detecting system carries out position detection, and the electric scraper is normally operated by the operation of an automatic control system and a center control chamber; the electric scraper supplies power for the super capacitor by an energy converting system when a lifting mechanism descends; an optical fiber is contained in the cable; and the position detecting system is interlocked with the automatic control system on the electric scraper by the cable and connected to the center control chamber by the cable. The invention has safe, energy-saving and environmental-friendly scraping operation of the mines, small tunnel section, small turning radius and small section of a well cylinder for carrying the electric scraper, is convenient to realize semi-automatic and automatic control and saves engineering investment.
Description
technical field [0001] The invention relates to the technical field of mine shoveling operations, in particular to a power supply method and power supply equipment for an electric shovel. Background technique [0002] At present, in mine shoveling operations, diesel shovels or electric shovels are usually used as the main shoveling machinery. There are several problems with scraper operations with these scrapers. The current main problems of diesel LHDs are: diesel shortage; loud noise; exhaust pollution, need to increase underground ventilation, and consume a lot of energy. Diesel scrapers can only use wireless communication, which has a narrow bandwidth and poor anti-interference ability. In addition, wireless communication still has a certain transmission dead angle. In operation, the diesel scraper uses its own diesel engine to generate electricity, and the electric scraper directly consumes electricity through the grid. Under the condition of completing the same actio...
