The invention discloses an elevator bucket anti-dropping control method and an elevator bucket anti-dropping control device. The elevator bucket anti-dropping control method comprises the following steps that firstly, working current parameters of an elevator bucket driving motor are detected; secondly, the working current parameters are compared with a preset parameter range, if the detected working current parameters exceed the preset parameter range, anti-dropping operation is carried out, a driving motor stops working, an anti-dropping device is switched into the anti-dropping state, and the anti-dropping device is prevented from falling. The method is adopted in a control system of a stirring station, current data of the elevator bucket driving motor are monitored in real time, and after the operating current of a speed reducer is higher than the curve A, the motor stops rotting, a motor brake device works, and the motor is protected. After the operating current of the speed reducer is lower than the curve C, the motor stops rotating, the motor brake device works to protect the motor, the anti-dropping device works, the elevator bucket is prevented from falling off, and the serious destruction caused by falling off of the elevator bucket is obviously reduced.
