摘要
目前我国在用垂直电梯中曳引驱动电梯占95%以上。近年来发生的电梯事故中,较多是因为电梯鼓式制动器失效导致了电梯轿厢非正常移动,造成人员伤亡。本文介绍了电梯驱动主机工作制动器的类型,总结了检验工作中电梯鼓式制动器的常见问题并分析了相关原因,进一步提出了电梯鼓式制动器拆解清洁的注意事项,为电梯制造单位、维保单位、检验单位等提供了技术指导。
At present,over 95%of vertical elevators in use in China are traction driven elevators.In recent years,some elevator accidents have occurred due to the failure of the elevator drum brake,resulting in abnormal movement of the elevator car and causing casualties.This article introduces the types of brakes for elevator,summarizes common problems with elevator drum brakes,analyzes relevant reasons,and further proposes precautions for disassembly and cleaning of elevator drum brakes.The article provides technical guidance for elevator manufacturing,maintenance,and inspection companies.
