摘　　要：自动取封盖装置是核电厂或核废物固化处理生产线必不可少的一套自动化设备,主要用于低、中水平放射性固体废物包装容器钢桶的取封盖操作。其中,钢桶定位、螺栓/螺孔定位以及桶盖抓取功能是其重要的三个功能。本文以我国沿海某市三个已运行的核电站项目中,三个不同设计模式的自动取封盖装置为例,探讨了实现其三个功能的机械电控结构及存在的设计问题。基于上述对比分析,本文针对钢桶定位、螺栓/螺孔定位以及桶盖抓取功能,提出了一些改进的设计思路,对于后续优化改进自动取封盖装置具有现实意义。The automatic capping device is an essential set of automated equipment for nuclear power plants or nuclear waste solidification and treatment production lines,mainly used for capping the steel drums of low and medium level radioactive solid waste packaging containers.Among them,the positioning of steel drums,bolt/screw hole positioning,and lid grabbing function are its three important functions.This article takes three automatic cover removal and sealing devices with different design modes in three operational nuclear power plant projects in a coastal city of China as examples to explore the mechanical and electrical control structures that achieve their three functions and the existing design problems.Based on the above comparative analysis,this article proposes a new design concept for the positioning of steel drums,bolt/screw hole positioning,and lid grabbing function,which has practical significance for optimizing and improving the automatic lid grabbing and sealing device in the future.
