摘要
在对液压电梯防沉降功能做了一些较大改进的基础上引入了曳引电梯的电气防剪切功能,从而解决了曳引电梯上的一个根本性的安全问题:制动器机械失效后的二次保护。制动器失效后的二次保护不是一种简单的再平层。而是一种利用了强迫关门、缓冲器等多种电梯安全保护装置的一种综合性安全保护措旅。
This paper Introduces traction elevator anti-shear function in the base of hydraulic elevator anti-sink functions to do some improvements, so as to solve a fundamental safety issues on the elevator: twice protection after brake mechanical failure. The twice protection after brake failure is not a simple re-level, but a kind of a comprehensive safety protection measures with the door nudging device, buffer, etc.
