The invention relates to a flexible guiding special lift car stabilizing device and method. The device is composed of a stabilizing support, a connecting mechanism and a self-locking mechanism. The connecting mechanism comprises connecting plates, final limit cams and stabilizing bars, and the self-locking mechanism comprises rockers, return springs, driving bolts, bearings, driven bolts and pins. When a lift stops on a floor, a car door is opened to drive the connecting mechanism to release self locking, the stabilizing bars are pushed into a shaft support so as to stabilize the lift car, and the self-locking mechanism returns to the self-locking state. After unloading and loading, the car door is closed, the connecting mechanism is driven to release self locking, the stabilizing bars are withdrawn, the self-locking mechanism performs self locking again, and the lift runs normally. The problem that the lift car sways when people or cargos enter or exit from the flexible guiding mining lift is solved, various safety problems caused by partial swaying during rerunning of the lift car are avoided, the lift car can be started stably after stopping on one floor, reliability and stability of the lift are improved, driving does not need to be set independently, and the flexible guiding special lift car stabilizing device is simple in structure, good in lift car stabilizing effect, low in cost and safe and reliable.
