摘　　要：制动器在电梯中,其工作价值和作用是十分必要的,如果制动器出现失效的情况,就可能导致电梯出现剪切或挤压伤害,会影响电梯的服务能力。因为制动器失效会造成危险依靠和其他安全部件的保护难题,甚至电梯的电气保护作用也无法得到保证,同时,上行超速保护器就可能出现无法正常工作的情况,而只有在电梯轿厢速度超过115%的额定速度时,才会出现电梯的安全保护,也就会引起电梯功能障碍问题,严重影响电梯的功能和作用。所以,制动器在稳定工作时,才能满足电梯的安全运行,为了满足电梯的安全运行,需要对制动器的工作原理进行了研究,对电梯制动失效的原因进行系统分析,并提出解决对策以供参考。The working value and function of brakes in elevators are very necessary.If the brakes fail,it may lead to shear or compression injuries in the elevator,which will affect the service capacity of the elevator.Because brake failure can cause dangerous dependencies and other safety components to be protected,and even the electrical protection function of the elevator cannot be guaranteed.At the same time,the upward overspeed protector may not work properly.Safety protection of the elevator only occurs when the elevator car speed exceeds 115%of the rated speed,which can cause elevator dysfunction and seriously affect the function and function of the elevator.Therefore,only when the brake works stably can it meet the safety operation of the elevator.In order to meet the safety operation of the elevator,it is necessary to study the working principle of the brake,systematically analyze the reasons for elevator brake failure,and propose solutions for reference.
