The invention relates to turnover equipment in a production process for a prefabricated cement plate for the high-speed railway, in particular to turnover equipment for a CRTS III type ballastless track plate for the high-speed railway. The axial two ends of a track plate bearing device are separately equipped with turnover devices. Each turnover device comprises a turnover shaft which is fixedly connected with the track plate bearing device and a swing oil cylinder connected with the turnover shaft, and the other end of the turnover shaft is connected with a hydraulic rotary joint. The turnover equipment for CRTS III type ballastless track plate for the high-speed railway is simple in structure, can perform turnover stop at any angle after feeding a formed track plate into the turnover equipment through an operation trolley, further performs track plate detection and transportation, is matched with a travelling crane more optional, and effectively improves working efficiency.
