Research on the device for measuring the engagement depth of bottom guide of landing door

Abstract

A large number of elevator safety accidents occur at the landing door. The bottom guide of landing door has the function of fixing the landing door and guiding. The previous measurement of the engagement depth of the bottom guide of landing door has drawbacks and the measurement accuracy is low. The insufficient engagement depth of the bottom guide of landing door will affect the strength of the landing door.In order to improve the measurement accuracy of the engagement depth of the bottom guide of landing door, this paper proposes a device for measuring the engagement depth of the bottom guide of landing door, analyzes its structure and working principle, and measures the engagement depth of the bottom guide of landing door through direct measurement and indirect measurement.Through the measurement and numerical analysis of the engagement depth of the bottom guide of landing door by the steel tape, inclined feeler gauge and the device for measuring the engagement depth of bottom guide of landing door, it is concluded that the measurement accuracy of the device for measuring the engagement depth of bottom guide of landing door can be improved compared with the steel tape and inclined feeler gauge.
