深井双折线式多层缠绕提升机钢丝绳的动态径向变形与动张力监测装置及方法 技术领域
本发明专利涉及一种深井双折线式多层缠绕提升机钢丝绳的径向变形及张力的动态监测装置及方法，能够模拟缠绕式提升系统中钢丝绳在加速、减速、匀速、急停等多种工作情况下所受拉力特性，可用于探究卷筒上每层钢丝绳的实时径向变形、卷筒外壁不同区域所受压力及钢丝绳张力的动态变化。
背景技术
矿山生产的全过程离不开矿山运输和提升工作，因此，运输和提升工作的好坏直接关系到矿上生产能否正常高效进行。矿井提升设备是矿山生产的咽喉，是集机、电、液于一体的大型复杂系统。它是矿山生产的一条生命线，主要用于提运矿石、煤炭、物料、人员和设备，是矿山井下生产系统与地面工业广场相连接的枢纽。随着矿井开采走向深部和现代化大型矿井安全高效生产的要求，多层缠绕式提升机的应用日趋大型化，随着卷筒的增长,重量和转动惯量增加,需要更大的电机,而且需要更大的布置空间，采用多层缠绕卷筒可以节省成本。双折线绳槽是适合多层缠绕的一种绳槽形式,它能有效地克服传统卷筒在多层缠绕方面的缺点,避免乱绳,有效地延长钢丝绳的使用寿命。并以其提升能力大，提升高度大，安全系数高，造价便宜等显著优点，被越来越多地用于深井及超深矿井的矿井提升中。随着矿井开采深度的增加，为了提高深井及超深矿井提升机的运输效率，提升装备必然向大提升载荷和高提升速度发展，这也为提升设备的安全性和可靠性提出了更高要求，因钢丝绳在长时间工作中会发生形变，特别是工况突然变化时钢丝绳所受拉力及张力易使钢丝绳发生断裂从而引起作业吊篮坠落事故，造成人员伤亡。
在摩擦提升机的提升过程中，由于可变的提升钢丝绳悬垂长度和惯性载荷的共同作用，提升钢丝绳在上提加速、匀速、减速一个周期的提升过程中，提升系统会发生振动，钢丝绳也承受动张力变化，特别是在提升的加速、减速阶段，钢丝绳的动张力振动较大，振动频率随着钢丝绳长度的减小而增大。振动使钢丝绳所受拉力及张力改变，钢丝绳产生径向形变，在长时间周期工作后影响钢丝绳寿命，引发提升机的恶性事故。因为每一层钢丝绳受到的力是不同且多样的，如果能检测出每一层钢丝绳的变形及张力就能有效预防矿井事故的发生。所以，提出一种深井提升钢丝绳径向变形及张力的动态监测装置及方法，探究卷筒上每层钢丝绳的实时径向变形、卷筒外壁不同区域所受压力及钢丝绳张力的动态变化是至关重要的。
现有提升机钢丝绳检测装置包括：专利号为ZL201220715786.1的实用新型专利公 开了一种多绳摩擦提升机钢丝绳张力在线监控装置，可以通过无线发射模块和压力传感器采集钢丝绳张力并通过无线方式发送至无线接收模块，不受提升机结构和运行状态的影响，实现对提升机钢丝绳动态张力的实时监测，然而不能检测每一层钢丝绳的径向形变量；专利号为ZL201420703971.8的实用新型专利公开了一种矿井提升机张力监测系统，实现了矿井钢丝绳张力远程实时监测，提高矿井提升机的安全性，然而，该系统检测钢丝绳形变使用的三点弯曲法精确度不高，不能精确地算出钢丝绳所受的张力；申请号为201510634389.X的发明申请公开了一种提升系统中钢丝绳张力测量方法，是一种间接测量方法，没有对钢丝绳进行直接接触，不破坏钢丝绳结构，该方法不能测量每层钢丝绳的张力值。
