轿厢上行超速保护装置是安装在曳引驱动电梯上,在电梯上行超速到一定程度时用来使轿厢制停或有效减速的一种安全保护装置。它一般由速度监控装置和减速装置两部分组成。通常采用双向限速器作为速度监控装置检测轿厢速度是否失控。减速装置则包括安全钳、夹绳器和安全制动器,分别作用于轿厢或对重、钢丝绳系统(悬挂绳或补偿绳)和曳引轮。安全制动器作为上行超速保护装置必须直接作用在曳引轮或作用于最靠近曳引轮的曳引轮轴上,目前在无机房电梯永磁同步电机上通常就是利用直接作用在曳引轮上的制动器作为上行超速保护。这种制动器机械结构设计冗余,符合安全制动器的要求,不必考虑其失效。同时由于它直接作用在曳引轮上,曳引机主轴、轴承等机械部件损坏不会影响其有效抱闸制停。当然,它不能保护如曳引条件被破坏,曳引轮和钢丝绳之间打滑等其它原因而引起的上行超速。这就引出一个问题:上行超速保护装置究竟应对哪些类型上行超速起作用?按照GB7588-2003《电梯制造与安装安全规范》的要求,上行超速保护装置需要对制动器制动失效和电机传动失效引起的上行超速起作用。因此,目前上行超速保护装置不能做到保护电梯所有的上行超速。
