A multi-wheel supporting turntable turnout comprises a bed plate, an underbed, supporting wheels, a driving device and a railway support frame. The bed plate is a circular thin sheet, a tramcar railway and a car puller railway are arranged on the upper surface of the bed plate, the lower surface of the bed plate is fixed with the underbed, the multiple supporting wheels are evenly distributed on the lower surface of the underbed along the circumferential direction of the bed plate and can rotate relative to the underbed, a wheel edge is arranged on each supporting wheel, the railway support frame is arranged below the underbed, and a hub of each supporting wheel is blocked on the railway support frame. The driving device is arranged on the railway support frame, the driving device is connected with the underbed, and the driving device can be used to drive the supporting wheels to revolve around the railway support frame. By means of the multi-wheel supporting turntable turnout, while the direction of a tramcar going out or coming in is changed, a car puller can push the tramcar through the turnout, manual or semi-manual operations are not needed any more to push the tramcar to move, and tramcar running in a wellhead tramcar yard is enabled to be safer.
