Description

一种摩擦提升机绳槽磨损量检测系统及检测方法 技术领域
本发明涉及一种提升机绳槽磨损量检测系统及检测方法，特别是摩擦提升机绳槽磨损量检测系统及检测方法。
背景技术
箕斗在提升过程中的各阶段，钢丝绳的受力是不同的。在箕斗的各个运行阶段，由于滚筒上的摩擦衬垫摩擦状况并不是理想状态下的均匀摩擦，使得滚筒在下放或者提升钢丝绳的过程中，钢丝绳长度不会完全相同从而造成绳长差，使得钢丝绳之间的张力不平衡，给提升安全和钢丝绳使用寿命造成了严重威胁。
因此研究滚筒摩擦衬垫磨损状况在提升系统运行过程中对提升钢丝绳张力的影响以及提升钢丝绳绳长差的影响，从而给多摩擦提升钢丝绳张力自动平衡装置的行程设计，以及延长钢丝绳的使用寿命，改善运输过程的安全性等具有重要意义。
在现有的技术中测量滚筒摩擦衬垫磨损量时需要将提升机停机，拆卸下摩擦衬垫。利用高精度的仪器才能检测出衬垫摩损量不仅耗时增加工作量，而且拆卸下来的摩擦衬垫不易重新定位安装，非常不利于工作生产。
发明内容

所述的检测方法：在提升机的前面安装有传感器支架，传感器支架的支撑轴与提升机转轴平行，激光位移传感器安装在传感器支架上，且与滚筒的的钢丝绳距离在激光位移传感器的工作量程内，在传感器支架上安装的激光传感器对准摩擦提升机的绳槽，绳槽的数目与激光传感器的数目相等；编码器安装在提升机的转轴上；所述的上位机与采集器的RJ45以太网口相连；
上位机设定同步时钟，控制信号通过以太网输入编码器和采集器，编码器与采集器同步工作，同步采集数据；激光位移传感器测量摩擦提升机上钢丝绳位移，采集器将位移数据通过以太网发送到上位机处理；上位机接收激光位移传感器和编码器定位信息分析处理摩擦提升机绳槽磨损。
作为一种优选方式：安装在传感器支架上的激光位移传感器的型号相同。
有益效果，由于采用了上述方案，滚筒摩擦衬垫磨损形貌由于其特殊结构难以直接测得，采用间接测量衬垫磨损形貌的测试系统与检测方法，简易控制实现在线检测摩擦提升机滚筒绳槽磨损状况。
优点：本发明提供的摩擦提升机绳槽磨损量检测系统及其方法，能够实现摩擦衬垫的磨损量实时快速在线检测，精确实时定位需要更换的摩擦衬垫，减轻了工人的劳动强度，提高钢丝绳的使用寿命，弥补工程上无法实时监测摩擦衬垫磨损量这方面的空白。
