电梯制动器常见失效形式与检验要点研究

Research on Common Failure Forms and Inspection Points of Elevator Brakes

随着电梯使用量逐年增加,电梯安全事故也频繁发生,其中电气制动器失效最为常见。一旦电梯制动失效,很可能造成电梯运行的不可控,产生冲顶或蹲底安全事故,给乘客生命安全带来巨大威胁,造成的后果极为严重,这也突出了电梯制动器日常检验工作的重要性。基于此,阐述了电梯制动器的主流形式和制动器功能,分析了电梯制动器的常见失效形式,并探究电梯制动器的检验要点。

With the increasing usage of elevators year by year,elevator safety accidents also occur frequently,among which the failure of electrical brakes is the most common.Once the elevator brake fails,it is likely to cause uncontrollable elevator operation,resulting in safety accidents such as hitting the top or squatting at the bottom,posing a huge threat to the safety of passengers.The consequences are extremely serious,which highlights the importance of daily inspection of elevator brakes.Based on this,elaborates on the mainstream forms and functions of elevator brakes,analyzes the common failure forms of elevator brakes,and explores the inspection points of elevator brakes.
