By setting an angle between the upper side of the electrode storage platform and the flipping platform, the electrode can roll down from the electrode storage platform to the flipping platform under the action of its own gravity. Then, the flipping hydraulic cylinder and the oil cylinder support cooperate to drive the flipping platform to flip, thereby driving the electrode flipping on the flipping platform. Due to the fact that the flipping action mainly relies on this utility model to greatly reduce the occupation of driving time and manual operation, it not only avoids the wear and tear on the electrodes caused by the lifting and moving of the vehicle, but also enables remote automatic operation, saving time and effort, and reducing the labor intensity of workers.
