一种矿用电梯 曳引绳 连接装置及其检测方法 技术领域
本发明涉及一种矿用电梯曳引绳连接装置及其检测方法，尤其适用于矿山大深度的矿用电梯。
 背景技术
随着建筑物高度的提高，电梯提升高度逐渐的增加，特别是矿井深度较大的提升采用电梯进行人员的运输，从而曳引绳张紧力的不均衡现象逐渐体现，导致曳引轮绳槽和曳引绳磨损的不均衡，造成轿厢在提升过程中剧烈的晃动。而目前矿用电梯使用的曳引绳张紧力调节装置，主要在曳引绳绳的端接处采用压缩弹簧形式或橡胶形式进行连接缓冲，虽起到了缓冲和减震的作用，但由于曳引绳制造的误差、材料的差异，在使用一段时间后易造成曳引绳张紧力不均衡，导致曳引轮绳槽磨损不均匀、轿厢运行不平稳、曳引绳磨损严重， 使用寿命低。
 技术问题
本发明的目的是克服已有技术中的不足，提供一种结构简单、曳引绳张紧力均衡，轿厢运行平稳、使用寿命长、性能可靠的矿用电梯曳引绳连接装置及其检测方法。
 技术解决方案
本发明的矿用电梯曳引绳连接装置，包括工控机，与工控机连接的信号采集器，还包括对称排列的用于连接曳引绳端的多个绳环，多个绳环上连接有固定在机房平台上或轿箱上的曳引绳张紧力调节装置；所述的曳引绳张紧力调节装置包括与多个绳环数目相同的多个液压缸和固定多个液压缸的柱塞拉板和缸体固定架，缸体固定架的下部设有连接液压管路与液压缸缸体油路的固定连接头，缸体固定架的上部设有连接多个液压缸柱塞的柱塞连接头，缸体固定架的上端设经销轴连接有与其相插接在一起的换向连接头，其下端设有固定缸体固定架与柱塞拉板的缸体固定架连接螺栓；曳引绳张紧力调节装置内设有与多个绳环数量相同的实时监测每个液压缸柱塞与液压缸缸体相对位移的多个拉线位移传感器，液压管路上有油压传感器，油压传感器和拉线位移传感器通过信号采集器与工控机相连接组成曳引绳张紧力与调节量检测系统。

本发明曳引绳连接装置的检测方法：
（1）通过连接在液压管路上的油压传感器实时监测缸体固定架内每个缸体液压油的压力，经信号采集器将采集的信号传输到工控机内进行数据处理分析，将空载初始压力值和重载下的压力值的压差、并根据载荷波动范围确定液压缸缸体压力的预设值范围；若液压管路的压力在预设值的范围内，则每个液压缸都正常工作，若超出预设值的范围，则液压缸有泄露液压油的现象，此时通过工控机进行分析处理并报警提示；
（2）通过拉线位移传感器实时监测缸体固定架内每个液压缸柱塞与液压缸缸体的相对位移，经信号采集器将采集的信号传输到工控机内进行数据处理分析，将液压缸柱塞的行程、并根据位移波动范围确定监测位移的预设值；若位移在预设值的范围内，则柱塞具有曳引绳张紧力的调节能力，若位移超出预设值的范围，则该曳引绳张紧力调节装置没有曳引绳张紧力的调节能力，此时通过工控机进行分析处理并报警提示。
