摘　　要：根据我国西部地区大型和特大型矿井建设需要,为提高50 t级箕斗装载的自动化、智能化水平,在分析现有装载方式使用情况及存在问题的基础上,提出国内首套50 t煤矿立井装载用板式定量输送机装载的方案,并对工艺流程和整机结构、链轮链条等关键部件可靠性,称重元件配置和计量精度,变频驱动智能调速控制等关键技术进行研究。研究表明,板式定量输送机装载速度连续可调,最大可达1.4 m/s、装载时间不大于40 s,满足50 t级箕斗装载的要求。研究结果为样机试制奠定基础,并为千万吨级安全高效立井开采矿井装载系统设计提供参考。According to the construction needs of the large and extra large mine in the western region of China,and in order to improve the automation intelligent level of 50 tons skip＇s loading,based on the existing shaft loading patterns and usage,a loading program with the first set measuring conveyor was proposed and its key technologies were researched,such as the whole structure,the key components chain sprockets design,precision weighing and measuring devices,automatic mode with a intelligent speed- regulation system of frequency conversion technology and others. The theoretical analysis showed that loading speed continuous operation and up to 1. 4 m / s,the loading time less than 40 s,met the requirements of 50 tons skip＇s loading. These results laid the foundation for the prototype trial,and provided reference for the shaft loading system design of ten- million ton level mine.
