近年来随着电梯数量的剧增,电梯尤其是新安装电梯由于安装单位的工艺、自检不到位等因素,电梯发生突然停车的故障时有发生,严重影响电梯运行的可靠性。笔者根据日常检验工作中发现的电梯突然停车故障现象,从门刀与门锁滚轮啮合、抱闸微动检测开关、张紧轮空间自由度、安全电路布线等方面进行分析,并提出相应的对策。1门刀与门锁滚轮啮合不当对某型号电梯做运行试验过程中发现该电梯运行至某一层,有时电梯会突然停车;检查门锁回路和安
In recent years, with the dramatic increase in the number of elevators, elevators, especially newly installed elevators, often fail to stop suddenly because of the installation process and self-test, which seriously affects the reliability of elevator operation. According to the phenomenon of sudden stop of elevator which is found in the daily inspection work, the author analyzes the door joggles and the lock of the door lock, the inching detection of the brake, the space freedom of the tension wheel and the wiring of the safety circuit, and puts forward the corresponding countermeasures . 1 Knife and door lock wheel improper engagement Run on a model elevator to do the test found that the elevator runs to a floor, and sometimes the elevator will suddenly stop; check the door lock circuit and security
