Power device and towed excavator transition method
The invention relates to the technical field of engineering machinery, in particular to a power device and a towed excavator transition method. The power device comprises a working motor, an output shaft of the working motor is connected with a transfer case, the transfer case is connected with a main pump, and the power device is characterized in that the end, away from the transfer case, of the output shaft of the working motor is connected with an output shaft of a walking motor, and the rated voltage of the walking motor is lower than that of the working motor; the transition method comprises the following steps: in a normal excavation state, connecting an external power supply to provide a power source, and disconnecting the connection between the vehicle-mounted battery and the walking motor; in the walking state, the external power supply is cut off, the external power supply cable is taken down, the vehicle-mounted battery is closed to be connected with the walking motor, and the walking motor is powered through the vehicle-mounted battery for walking. When the excavator is transferred, only the walking motor needs to be started without depending on an external power supply.
本发明涉及工程机械技术领域，具体的，涉及一种动力装置及拖电式挖掘机转场方法。该动力装置包括工作电机，工作电机的输出轴连接有分动箱，分动箱连接有主泵，其特征在于，工作电机的输出轴远离分动箱的一端连接有行走电机的输出轴，行走电机的额定电压低于工作电机的额定电压，还包括车载电池，车载电池与行走电机电连接该转场方法包括以下步骤：正常挖掘状态，连接外部电源提供动力源，断开车载电池与行走电机的连接；行走状态，断开外部电源，并取下外部电源电缆，闭合车载电池与行走电机连接，通过车载电池给行走电机供电，用于行走。挖掘机转场时仅需要启动行走电机，不依赖外部电源。
