Supporting device and wind generating set

The invention relates to the technical field of wind power, and discloses a supporting device and a wind generating set, the supporting device comprises a supporting platform, an outer supporting ring frame is detachably mounted at the bottom of the outer edge of the supporting platform, and two bilaterally symmetrical guide rails are welded to the position, close to the middle, of the supporting platform; a lifting plate is slidably mounted between the two guide rails, and a lifting driving device is arranged at the bottom end of the middle of each guide rail and used for driving the lifting plate to move between the two guide rails. According to the device, the arranged lifting driving device is used for extruding plates at the two ends, vertical falling of the middle plate is achieved, the electrical equipment can be carried to the lifting plate, and then the lifting plate and the electrical equipment on the lifting plate are lifted through the lifting driving device till the lifting plate is completely la
