自动扶梯和自动人行道防逆转保护研究

Research on Anti-reverse Protection of Escalators and Moving Walks

自动扶梯和自动人行道客流量过大、超载、超负荷运载是自动扶梯或倾斜式人行道发生逆转事故的常见原因,一旦发生逆转就会造成很大的人身伤亡事故,对此需要给予防逆转保护问题以高度重视。本文阐述了自动扶梯和自动人行道运行作用机理,明确设置防逆转保护装置的目的及要求后,分析了逆转原因,提出了防逆转保护装置检测方法以及具体防护措施。

Excessive passenger flow,overloading,and overloading of escalators and moving walks are common causes of reversal accidents on escalators or inclined walkways.Once the reversal occurs,it will cause a lot of personal casualties,and it is necessary to attach great importance to the problem of anti-reversal protection.This paper expounds the operation mechanism of escalators and moving walks,and then clarifies the purpose and requirements of the anti-reversal protection device,analyzes the reasons for the reversal,and proposes the detection method and specific protective measures of the anti-reverse protection device.
