Adjustable rotary rotor maintenance platform

The invention discloses an adjustable rotary rotor maintenance platform which can rotate and adjust a motor rotor, so that the operation of maintenance personnel is facilitated. According to the technical scheme disclosed by the invention, the adjustable rotary rotor maintenance platform comprises a supporting platform and a sliding platform, wherein the sliding platform is mounted on a longitudinal slideway of the supporting platform; supporting wheels for providing supporting points for a motor rotor shaft are two rollers used in pairs and are arranged on the sliding platform; the supporting platform is an oblique plane with slideways on the two sides, a lifting window is formed in the oblique plane, and a lifting device is arranged under the lifting window. When the motor rotor is required to be repaired, the lifting device descends, and the outer end of the rotor falls on a bearing and can rotate at will; when the lifting device ascends, the outer end of the rotor is lifted up and cannot rotate, so that t
