摘　　要：介绍了一种在煤矿井下采用磨料水射流切割技术切割钢管的装置,该切管装置通过齿轮传动和蜗杆传动使磨料水射流切割喷嘴绕直立在井下工作面的管做圆周运动,将套管切断。同时介绍了该切管装置各组成部分,并对其传动系统进行了计算分析。This paper introduces a steel pipe cutting apparatus that is designed to carry out steel pipe cutting by employing abrasive water jet technology in underground coal mine environment.With the help of gear driving and worm driving,abrasive water jet cutting nozzle goes around the steel pipe standing vertically at the underground face and performs the steel pipe cutting in-situ.Besides,this article also introduces the component parts of this pipe cutting device and a calculation is made on its transmission system.
