| Abstract: | The engagement state reliability of elevator door lock locking element is an important guarantee for ensuring safe operation of the elevator door system.Aiming at the problems of insufficient measurement accuracy,low degree of automation,and low versatility of the existing elevator door lock engagement length inspection methods,a sensor-based detection method is proposed.The principle of on-off detection of electromagnetic induction switch and the working principle of contact displacement sensor are analyzed.On this basis,the door lock engagement length detecting device was developed,and the inspection steps using the device were introduced.The actual measurement results show that the inspection method and the inspection device can realize the quick and accurate inspection of the door lock engagement length,and the data repeatability is high. |
