Description

矿用电梯柔性导轨张紧力自动调节装置及方法 技术领域
本发明涉及一种矿用电梯柔性导轨张紧力自动调节装置及方法，尤其适用于矿山井下刚性导轨无法满足的电梯导轨系统。
 背景技术
目前，在电梯导向系统方面主要采用刚性导轨，由于刚性导轨在设计、制造和安装过程中存在误差，同时又由于矿井井筒壁承受巨大压力，井筒变形，其导轨侧向倾斜、弯曲变形、接头错位和局部凸起时常发生，从而造成轿厢在提升运行过程中剧烈的振荡；严重时，依赖于低间隙导轨的电梯滑动导靴或滚动导向轮被卡住，造成电梯轿厢卡在井筒内，给矿用电梯的安全运行带来巨大的隐患，轿厢内的乘人构成生命安全危险。
在现有的矿山竖井中，目前已有钢丝绳罐道的柔性导轨，主要是基于井底重锤拉紧的钢丝绳罐道系统、液压螺杆拉紧的钢丝绳罐道系统以及基于快速卡绳装置的液压张紧装置。其中，基于井底重锤拉紧的钢丝绳罐道系统的优点是拉紧力稳定，但提升容器内货物等越重，拉紧重锤的质量就会越大，所占的空间也越大，因此需要开凿较深的井底水窝，若水窝内由于煤块等杂物的撒入，造成井底水窝被填高即重锤的拉紧力减少，致使轿厢横向偏摆严重，同时调整张紧力时工作效率低，工人强度大，且重锤的精确重量难调整；液压螺杆拉紧的钢丝绳罐道系统虽克服了重锤拉紧的许多不足，但是楔块装置加工困难、楔块不容易进入固定装置的底部，从而造成钢丝绳与楔块之间打滑，致使罐道钢丝绳从顶部坠入；而基于快速卡绳装置的液压张紧装置虽然克服了重锤式和螺杆式液压拉紧系统的弊端，但当钢丝绳由于持续张力作用造成永久伸长而使钢丝绳张紧力减小时，无法自动的实现钢丝绳的张紧，必须要工人松开钢丝绳夹板，然后再继续张紧，若油缸的行程不够，则张紧力达不到，需要重新卡绳后张紧，致使提升系统低效率。
根据以上分析可以发现，目前矿用电梯刚性导轨无法满足正常提升、尚没有矿用电梯钢丝绳系统；基于井底重锤拉紧的钢丝绳罐道系统的拉紧重锤质量大、所占的空间大、且重量不易调节；液压螺杆拉紧的钢丝绳罐道系统的楔块装置加工困难，容易造成钢丝绳与楔块之间打滑；基于快速卡绳装置的液压张紧装置的张紧力无法自动调节，且效率低等问题。
 技术问题
本发明的目的是提供一种结构简单、易加工、性能可靠、安装和维护简单，同时具有纵向导向、横向偏摆约束，并能够实时监测导轨的张紧力以及根据监测的张紧力自动调节的矿用电梯柔性导轨张紧力自动调节装置及方法。
 技术解决方案
本发明的矿用电梯柔性导轨张紧力自动调节装置，包括分别连接在钢丝绳两端的井口自动拉紧装置和井底固定装置，井口自动拉紧装置连接有液压系统和张紧力检测系统；所述的井口自动拉紧装置包括设在上承载梁上的下固定器座，下固定器座上设有位于钢丝绳左右两侧的拉紧油缸缸体，并设有位于钢丝绳前后两侧的销轴固定座及支撑架，拉紧油缸缸体的前后两侧设有防坠座，拉紧油缸缸体内的柱塞经销轴连接在固定于销轴固定座底部的销轴座上，销轴固定座的下方设有防止钢丝绳坠落的防坠卡绳器，销轴固定座的上方设有钢丝绳的拉紧固定卡绳器，支撑架上设有固定左右两个导向柱的上固定器座，上固定器座上设有调绳导向卡绳器；销轴固定座的两侧设有沿导向柱上下移动的导向槽；所述的井下固定装置包括设在下承载梁上的固定板，固定板上设有固定在钢丝绳下端的固定卡绳器。
所述的张紧力检测系统由设在液压系统管路上的油压传感器、与油压传感器相连的信号采集器和与信号采集器相连的实时检测工控机构成；
本发明的矿用电梯柔性导轨张紧力自动调节方法，通过油压传感器实时监控钢丝绳的张紧力，通过信号采集器将采集到的数据传输给张紧力检测系统的工控机，进行分析处理；
当钢丝绳的张紧力低于工控机设定的下限值时，工控机驱动液压系统给拉紧油缸缸体底部管路内加压而推动柱塞，柱塞将固定在销轴固定座的拉紧固定卡绳器往上推而拉紧钢丝绳；
当柱塞一次上升无法使钢丝绳的张紧力达到工控机设定的上限值，油缸另一侧加压，柱塞将固定在销轴固定座上的拉紧固定卡绳器从上部拉回，拉紧固定卡绳器的楔形块与钢丝绳分离，而调绳导向卡绳器和防坠卡绳器由于楔形块的自锁特性，钢丝绳被楔形块夹紧，并保持钢丝绳的张紧力；随后，继续往拉紧油缸缸体的底部管路加压将柱塞往上推，循环往复一次或几次直至钢丝绳的张紧力达到工控机设定的上限值。
 有益效果
本发明能够起到轿厢在提升运行过程中的纵向导向、横向偏摆约束，导轨能够克服井筒的侧向变形，并使矿用电梯的轿厢在柔性导轨上稳定的运行，同时能够实时监测导轨的张紧力，并根据张紧力的大小，自动的进行调节，实现自动监测、自主调节的功能，同时也适用于矿井罐笼和箕斗的钢丝绳罐道导向系统。具有如下优点：
（1）柔性导轨可以保持所要求的张紧力，能够起到纵向导向作用、横向偏摆约束，实现轿厢的可靠运行；
（2）相对刚性导轨，安装、维护简单、成本低，尤其适用于侧向变形较大、刚性导轨无法满足的矿井井筒，解决了传统矿用电梯轿厢在刚性导轨上提升过程中噪音大、横向振动剧烈，甚至被卡住的问题；
（3）张紧力自动调节系统能够实时的监测钢丝绳的张紧力，并自动的对张紧力进行调节，实现了张紧力的自动监测、自动校正，提高了轿厢乘坐的安全、可靠和舒适性。

图4图5所示，所有固定在钢丝绳3上的卡绳器结构均相同，只是大小不同，每个卡绳器结构包括中部开有楔形槽的前夹板1-19与后夹板1-20，前后两夹板通过连接螺栓1-18连接固定，楔形槽内对称设有两块可以上下移动的楔形块1-15，两块楔形快1-15相对的一面上开有圆弧绳槽，另一面与楔形槽相配合之间设有带有滚柱1-16的栅架1-17。
图6图7所示的井下固定装置2中，下端的固定卡绳器2-5反向设在钢丝绳3上，通过固定板2-3安装在下承载梁2-1底部，由固定螺栓2-2固定，该固定卡绳器2-5相对调绳导向卡绳器1-8、拉紧固定卡绳器1-10和防坠卡绳器1-12反向倒置安装。钢丝绳3同样穿过固定卡绳器2-5的楔形块1-15的中心绳槽，并通过绳卡2-4进行夹紧。

本发明的矿用电梯柔性导轨张紧力自动调节方法：
（1）首先将调绳导向卡绳器1-8、拉紧固定卡绳器1-10和防坠卡绳器1-12的楔形块1-15提起，钢丝绳3从调绳导向卡绳器1-8、拉紧固定卡绳器1-10和防坠卡绳器1-12的楔形块1-15中心绳槽穿过，直至井底；将调绳导向卡绳器1-8的楔形块1-15下放卡住钢丝绳3，井底钢丝绳3同样穿过倒置放置的固定卡绳器2-1的楔形块1-15中心绳槽，经固定卡绳器2-1的楔形块1-15夹紧并由绳卡2-4固定，然后连接在井底的下承载梁2-3上；随后，将拉紧固定卡绳器2-1和防坠卡绳器1-12的楔形块1-15下放，并将拉紧油缸缸体1-2内的柱塞1-3往上推，带动拉紧固定卡绳器1-10往上运行，由于楔形块1-15的自锁特性，钢丝绳3被调绳导向卡绳器1-8夹紧并被向上拉起，井底固定卡绳器2-1同样由于楔形块1-15的自锁特性而被夹紧；
（2）拉紧油缸缸体1-2内的压力通过油压传感器4-1实时监测，并将信号采集仪采集到的数据传输给工控机4-3，进行分析处理；
若钢丝绳3的张紧力低于工控机4-3设定的下限值时，工控机4-3驱动液压系统5给拉紧油缸缸体1-2底部管路内加压而推动柱塞1-3，柱塞1-3将固定在销轴固定座1-11的拉紧固定卡绳器1-10往上推而拉紧钢丝绳3；
若柱塞1-3一次上升无法使钢丝绳3的张紧力达到工控机4-3设定的上限值时，柱塞1-3将固定在销轴固定座1-11上的拉紧固定卡绳器1-10从上部拉回，拉紧固定卡绳器1-10的楔形块1-15与钢丝绳3分离，而调绳导向卡绳器1-8和防坠卡绳器1-12由于楔形块1-15的自锁特性，钢丝绳3被楔形块1-15夹紧，并保持钢丝绳3的张紧力；
随后，继续往拉紧油缸缸体1-2的底部管路加压将柱塞1-3往上推，柱塞1-3带动拉紧固定卡绳器1-10往上运行，在拉紧固定卡绳器1-10内的钢丝绳3将再次被夹紧并被向上拉起，从而进一步增大了钢丝绳3的张紧力，循环往复一次或几次直至钢丝绳3的张紧力达到工控机4-3设定的上限值。
（3）最后，若液压系统5出现故障，拉紧固定卡绳器1-10被迅速拉回时，则由防坠座1-13将拉紧固定卡绳器1-10挡住，从而保护拉紧油缸缸体1-2和柱塞1-3，此时钢丝绳3由拉紧固定卡绳器1-13、调绳导向卡绳器1-8和防坠卡绳器1-12三者夹紧来保持张紧力， 并由液压系统5的油压传感器4-1监测，并将信号通过采集仪4-2传输给工控机4-3进行故障的处理。
