The invention discloses a lifting device and a control method for preventing an elevator car from accidentally moving. The lifting device comprises a lifting assembly, a detection assembly and a control assembly; the lifting assembly comprises the elevator car, a support frame and a driver, the elevator car is movably connected to the support frame, the driver is used for driving the elevator carto lift on the support frame, and the elevator car is provided with a car door switch assembly; the detection assembly can detect whether the elevator car moves accidentally or not after a car door ofthe elevator car is opened by the car door switch assembly; and the control assembly comprises a controller, wherein the driver, the detection assembly and the car door switch assembly are all electrically connected with the controller. When the car door of the elevator car is opened under drive of the car door switch assembly, the detection assembly detects whether the car moves accidentally ornot. If a movement accident occurs, the controller immediately responds to brake the elevator car, so that shearing accidents caused by abnormal movement of the elevator car when workers enter and exit from the elevator car are avoided, and production safety is ensured.
本发明公开了一种升降装置及防止轿厢意外移动的控制方法,升降装置包括升降组件,升降组件包括轿厢、支撑架和驱动器,轿厢活动连接在支撑架上,驱动器用于驱动轿厢在支撑架上升降,轿厢设有轿门开关组件;检测组件,轿门开关组件将轿厢的轿门打开后检测组件能够检测轿厢是否发生意外移动;及控制组件,控制组件包括控制器,驱动器、检测组件和轿门开关组件均与控制器电性连接。当轿厢的厢门在轿门开关组件的驱动下打开后,检测组件检测轿厢是否有发生意外移动,如果发生了移动意外,则控制器立即做出反应,以对轿厢进行制动,从而避免工作人员进出时轿厢异动导致的剪切事故,保证了生产安全。
