The biggest difference is that the roof needs to be equipped with a collector pole device for taking power from the high-voltage power grid. In the prior art, the collector rod is usually lifted and lowered by a cylinder, and then a collector rope is connected to the collector rod. When the net is touched, the cylinder needs to be cut off first, the collector rod is quickly raised to the highest position, and then the collector rod is pulled to adjust the current collecting rod to overlap with the power grid; during the vehicle traveling, once the vehicle is disconnected, the driver needs to stop immediately. Through manual operation, the cylinder intake pushes the collector rod to quickly drop to the roof limit position, and finally performs the catenary operation.
