Semi-automatic lifting device convenient for moving battery into battery rack and control method of semi-automatic lifting device

The invention relates to a semi-automatic lifting device convenient for moving a battery into a battery rack and a control method of the semi-automatic lifting device. The semi-automatic lifting device comprises a lifting platform, an underframe, a bracket, a driving mechanism, proximity sensors and an electric control cabinet equipped with control buttons, wherein front feet at the top of the bracket are connected with the back side of the lifting platform in a sliding manner, and rear feet at the top of the bracket are fixedly connected with the back side of the lifting platform; rear feet at the bottom of the bracket are fixedly connected with the underframe; front feet at the bottom of the bracket are movable; the driving mechanism is connected with the bracket; the proximity sensors are arranged at the front end of the side edge of the underframe and connected with the electric control cabinet; and the electric control cabinet is connected with the driving mechanism. The control method comprises the following steps: the electric control cabinet receives setting signals of the control buttons and sends control signals to the driving mechanism to control the lifting platform to ascend and descend; and when the proximity sensors detect the fact that the lifting platform reaches the height of a target layer, the battery is slightly pushed into a placement layer of the battery rack. The semi-automatic lifting device and the control method have the advantages that the control is convenient, and an operator does not need to continually press the control buttons for control, so that both time and labor are saved and the efficiency is improved.
