摘　　要：摩擦式提升机是一种普遍用于地下矿山竖井中的提升装置,是提升矿物、人员及一些矿用机械的主要装置。钢丝绳在长期运行中会受到多种力的作用,产生复杂的反弹波,首绳的反弹波时间差能有效反映钢丝绳的状况,通过对首绳反弹波时间差的检测,可以提前发现钢丝绳存在的缺陷,及时消除安全隐患。基于此,开发一种能够准确检测钢丝绳反弹波的装置对保障提升机的安全运行具有重要意义。文章分析了摩擦式提升机钢丝绳反弹波的弹性波理论和振动分析,阐述了钢丝绳距离调整机构、自锁脱钩机构和随动转换机构设计,展示了装置机械结构对钢丝绳反弹波的高效检测,旨在提升摩擦式提升机的运行安全性。Friction elevator is a lifting device commonly used in vertical and inclined coal mines.It is the main device for lifting minerals,personnel and some mining machinery.The steel wire rope will be affected by various forces during long-term operation,resulting in complex rebound waves.The time difference of the rebound wave of the first rope can effectively reflect the condition of the steel wire rope.By detecting the time difference of the rebound wave of the first rope,defects in the steel wire rope can be discovered in advance.Eliminate safety hazards promptly.Based on this,developing a device that can accurately detect the rebound wave of the wire rope is of great significance to ensure the safe operation of the hoist.This article analyzes the elastic wave theory and vibration analysis of the friction elevator wire rope rebound wave,explains the design of the wire rope distance adjustment mechanism,self-locking decoupling mechanism and follow-up conversion mechanism,and demonstrates the efficient detection of the wire rope rebound wave by the mechanical structure of the device,aiming to improving the operational safety of friction hoists.
