The development history of scraper conveyor technology(Part four):intelligent complete equipment
The coal workface robotic group includes intelligent scraper conveyor,which not only have adaptive efficient transportation of coal flow,but also guides the intelligent shearer to cut coal along the working face and pull the intelligent hydraulic support to safely support the rock roof,so the intelligence of scraper conveyor directly affects the intelligence of the coal mining machine group.The technologies of broken chain monitoring and protection,real-time sensing of chain tension,online monitoring of coal flow and automatic straightening of fuselage are the key sensing and control elements of intelligent scraper conveyor.At present,these technologies have reached mature application and provide important guarantee for unmanned operation of scraper conveyor.Since 2010,the intelligent technology innovation of scraper conveyor in China has accelerated,and the intelligent scraper conveyor with ultra-large power and ultra-long haul has been successfully developed,thereby constructing a super intelligent mining working face.It was pointed out that the the intelligent scraper conveyor drived by permanent magnet motor,intelligent capacity sensing scraper chain,all-wear-resistant integral forming middle groove,digital twin control system will become the development directions of the new generation of advanced intelligent scraper conveyors,so as to promote the intelligent mining face in coal mine entering to the advanced intelligent level.
