Discussion on Inspection of Comb Plate Protection Device for Escalator

检规TSG T7005—2012《电梯监督检验和定期检验规则—自动扶梯与自动人行道》对梳齿板及其保护装置的检验提出相应规定。梳齿板异物卡入是扶梯常见故障点以及事故高发点,本文通过对梳齿板保护装置试验方法的说明探讨,阐述了在实际检验中,根据不同场所不同工况因地制宜,不仅要求梳齿板开关可靠动作,而且要求梳齿板开关的机械触发装置应可靠有效。

Relevant instructions has been made for comb plate and its protection device according to TSG T7005： 2012 ＂Regulation for Lift Supervisory Inspection and Periodical Inspection-Escalators and Moving Walks＂. Comb plate biting is a common fault and accident point. With the discussion of the experimental method of comb plate protector, this article illustrates that we should act according to different conditions and various circumstances in practice. It not only requires the reliable operation of the comb plate switch, but also requires the mechanical trigger of the comb plate switch to be reliable and effective.
