我矿现有WK-4电动挖掘机3台,提升减速器作为该设备的主要和关键部分,在电动挖掘机提升过程中,扮演着铲斗上下升降动力源的角色,其联轴器又是传递该系统中动力的主要部件,通过设备的运行和发生的事件进行分析,结合设备现状、工作环境和设备运行频率,原始联轴器的联接方式有一个致命的薄弱环节,存在着设计上的缺陷,为确保安全,有必要对其进行技术改进。
There are 3 WK-4 electric excavators in our mine. As the main and key part of this equipment, the reducer is used as a power source for lifting and lowering the bucket during the electric excavator hoisting process. The coupling is also Transmission of the main components of the system power, through the operation of the equipment and the occurrence of the incident analysis, combined with equipment status, work environment and equipment operating frequency, the original coupling coupling has a fatal weak link, there is a design Defects, in order to ensure safety, it is necessary to make technical improvements.
