电梯层门的定期检验及案例分析

Periodic Inspection and Case Analysis of Elevator Landing Door

层门属于电梯的重要部件之一,它把乘客和井道、轿厢进行有效隔离,让乘客拥有一个安全良好的使用空间,有效保障乘梯人员的安全性和舒适性。层门若在带病情况下运行,乘坐电梯的人员将面临严重的安全威胁,甚至造成剪切、坠落等事故,因此乘客的乘梯安全很大程度上取决于电梯层门是否处于正常使用状态。为确保层门能够充分发挥出自身功能,减少甚至避免因层门引起的事故发生,层门的安全检验成为主要的研究对象。简要阐述了层门的结构形式,重点介绍了层门检验的主要对象和检验细节,最后对检验过程中碰到的层门滑块与防脱钩装置不能契合、层门副门锁动作不可靠两则案例进行分析探讨,为后期的检验提供参考。

Landing door is one of the important parts of elevator.It effectively isolates passengers from hoistway and car,so that passengers have a safe and good use space,and effectively ensures the safety and comfort of elevator passengers.If the landing door runs in the case of illness,the elevator passengers will face serious safety threats,and even cause accidents such as cutting and falling.Therefore,the elevator safety of passengers largely depends on whether the elevator landing door is in normal use.In order to ensure that the landing door can give full play to its own function and reduce or even avoid accidents caused by the landing door,the safety inspection of the landing door has become the main research object.The structural form of the landing door was briefly expounded,the main objects and inspection details of the landing door inspection were introduced.Finally,the two cases that the sliding block of the landing door and the anti decoupling device can not fit and the action of the auxiliary door lock of the landing door is unreliable were analyzed and discussed,so as to provide reference for the later inspection.
