【摘要】：针对长运距大型带式输送机运距长,线路较复杂等问题,以国内单部最长运距为12.8 km的王家岭煤矿主平硐带式输送机为研究对象,介绍了大型带式输送机动态分析、"头三尾一"的多点驱动、高压多电平变频调速驱动、多点布置中继线和光缆总线等关键技术与创新,指出了试生产期间的主要运行指标与理论动态分析的主要差异,同时,针对设计中存在的主要技术问题,提出长运距带式输送机宜在回程带面加设输送带翻转装置,长运距大型带式输送机宜在头部驱动滚筒加设逆止器等解决方案。经实践结果表明,在矿井主运输系统设计中综合运用以上技术措施,可有效确保主平硐带式输送机的安全可靠运行,并为长运距大型带式输送机设计提供理论技术支持。
[Abstract]:Aiming at the problems of long distance and complex line of large belt conveyor with long distance, the main adit belt conveyor of Wangjialing Coal Mine with the longest distance of 12.8 km in domestic is taken as the research object. This paper introduces the key technologies and innovations in dynamic analysis of large belt conveyors, multi-point drive of "first, third and tail", high voltage multilevel variable frequency speed regulation, multi-point arrangement of trunk lines and optical cable bus, etc. This paper points out the main differences between the main operating indexes and the theoretical dynamic analysis during the trial production period. At the same time, aiming at the main technical problems existing in the design, it is suggested that the long distance belt conveyer should be equipped with the conveyor belt flip device on the backhaul belt surface. The long distance large belt conveyor should be equipped with reverse stop in the head drive drum. The practical results show that the above technical measures should be comprehensively applied in the design of mine main transportation system. It can effectively ensure the safe and reliable operation of the main adit belt conveyor and provide theoretical and technical support for the design of large belt conveyor with long distance.
