近年来,随着金川矿山矿石产量的增加,矿石提升系统的使用频率也随之上升。为保证提升系统长周期安全运行,需要及时对其进行维护保养。摩擦式提升机绳槽衬块是提升机的关键部件[1],其摩擦力的大小是矿石提升的重要保障,准确掌握绳槽衬块的深度[2]尺寸是设备维护的重点。传统的绳槽深度测量方法大多利用深度尺或百分表,存在诸多不足,笔者设 In recent years, with the increase of ore production in Jinchuan Mine, the frequency of ore lifting system has also risen. To ensure long-term system safety and operation, it needs timely maintenance. Friction hoist rope groove pad is a key component of the hoist [1], the size of its friction is an important guarantee for ore lifting, accurate understanding of the depth of rope groove pad [2] Size is the focus of equipment maintenance. Most of the traditional rope groove depth measurement using depth gauge or dial indicator, there are many deficiencies, I set
