新型自动扶梯防逆转保护装置的设计及试验研究
摘要
Abstract
Some escalators are not provided with additional brakes and mechanical anti-reverse protection devices when they leave the factory.Once the drive chain is broken,the escalator will reverse and slide,which poses a safety risk.The traditional anti-reverse protection device is large in size and complex in structure,so it is extremely difficult to install it after finishing manufacturing.Based on the rotation characteristics of escalator steps in the lower machine room,a new type of escalator anti-reverse protection device was designed,which is simple in structure and easy to install,and can directly stop the steps.Samples made according to its design proposal has been tested in the field.The results show that the protection device can stop the elevator when the escalator reverses,solving the difficulty in installing the anti-reverse protection device.关键词
