At this time, the guide trolley drives the current collector to slide on the safety slide wire 41 to take power, and transmits the power to the electric control system on the trolley through the cable and the conductive slip ring 73 to supply power to the translation motor.

[0068] Compared with the prior art, the rotating and transferring trolley platform and the power receiving device thereof provided by the present application have the following advantages:
