摘要 |
The invention relates to a mobile rotary drive for a wind rotor of a wind power plant having a frame (1) comprising a drive wheel for driving a segment of a rotor shaft (9) of the wind power plant and a drive set (3) which drives the drive wheel in rotation as a drive pinion, wherein the drive wheel is a friction wheel (33) and interacts with a pressing device (2) in such a way that the pressing device (2) generates a force which presses the friction wheel (33) onto the segment with the result that the friction wheel (33) can apply a drive torque to the segment through friction, wherein a torque support (4) for supporting an opposing torque to the drive torque generated by the friction wheel (33) is also provided. Thanks to the friction wheel drive, there is no need for specific pre-equipping of the wind power plant. The invention makes available a mobile rotary drive which can be transported from one wind power plant to another. |
