The invention discloses a stage board rotating device of a butterfly-shaped stage. A stage board comprises a rotating platform, a large swinging turntable and a small swinging turntable which are combined, the rotating device comprises a hollow fixing frame, a hydraulic
station and a
drive motor, the rotating platform is of a hollow structure and comprises a horizontal platform board and a hollowannular support column fixedly connected with the horizontal platform board, the horizontal platform board of the rotating platform is placed on the hollow fixing frame, the top of the hollow fixing frame is provided with an inner ring rail, the lower end face of the horizontal platform board is provided with an inner ring bearing wheel which is placed in the inner ring rail to be matched with the inner ring rail, the lower end face of the support column of the rotating platform is provided with an outer ring bearing wheel which is driven by the
drive motor, and the hollow fixing frame is provided with an outer ring rail matched with the outer ring bearing wheel. The rotating platform can be driven through the
drive motor to rotate, and has a good stage
production effect; and due to the adoption of a bottom wheel and side wheels, the stability during the integral operation of the stage is effectively improved.
