The invention provides an elevator cage door fault detection method and device and an elevator. The fault detection method comprises the steps that an opening and closing instruction is received, and a cage door lifting mechanism is controlled to execute the opening and closing instruction; the real-time torque of a driving motor in the cage door lifting mechanism is detected; determining whether the elevator cage door has an operation fault according to the real-time torque; and under the condition that the elevator cage door has the operation fault, the cage door lifting mechanism is controlled to stop executing the opening and closing instruction. After the cage door lifting mechanism starts to start and executes the opening and closing instruction, the real-time torque of the driving motor can be detected, and whether the elevator cage door is stuck or not can be judged according to the real-time torque, so that automatic identification of the stuck fault of the elevator cage door is realized; in addition, under the condition that the elevator cage door is determined to be stuck, the cage door lifting mechanism can be automatically controlled to stop driving of the current instruction, corresponding processing is carried out, and then the purpose of eliminating potential safety hazards is achieved.

    本发明提供一种升降机笼门故障检测方法、故障检测装置及升降机,故障检测方法包括:接收启闭指令并控制笼门升降机构执行启闭指令;对笼门升降机构中驱动电机的实时转矩进行检测;根据实时转矩确定升降机笼门是否出现运行故障;在升降机笼门出现运行故障的情况下,控制笼门升降机构停止执行启闭指令。则在笼门升降机构开始启动并执行启闭指令之后,可以通过对驱动电机的实时转矩进行检测并根据实时转矩判断出升降机笼门是否出现卡死故障,从而实现对升降机笼门出现卡死故障的自动识别,此外在确定升降机笼门出现卡死故障的情况下,还可以自动控制笼门升降机构停止当前指令的驱动,并进行相应的处理,进而起到消除安全隐患的目的。
