深度指示器是矿井提升机的重要组成部分,如何实现准确、实时地判断提升容器在井筒中的位置,保证提升机安全运行以及实现提升机准确、安全减速停车,成为矿井安全生产的重大研究课题。针对现阶段使用的矿井深度指示器(牌坊式和圆盘式)存在误差大、功能单一、占用空间大、结构笨拙,存在较大安全隐患等问题,介绍了几种国内外正在研究或使用的新型深度指示器的工作原理和设计方法并分析了其特点,对矿山实际应用中设备的选型及技术改造等具有一定的指导意义。
Depth indicator is an important part of the mine hoist. How to realize the accurate and real-time judgment on the position of lifting the container in the wellbore, to ensure the safe operation of the hoist and to realize the accurate and safe deceleration of the hoist becomes a major research topic in the mine safety production . In view of the problems such as large error, single function, large occupied space, awkward structure and big potential safety hazard of mine depth indicator (arch and disk type) used in the present stage, several kinds of research and application The working principle and design method of the new depth indicator and its characteristics are analyzed. It is of guiding significance to the equipment selection and technical transformation in the practical application of the mine.
