Mobile rotary drive for a rotor of a wind power plant
View Patent ↗The invention relates to a mobile rotary drive for a wind rotor of a wind power plant having a frame comprising a drive wheel for driving a segment of a rotor shaft of the wind power plant and a drive set which drives the drive wheel in rotation as a drive pinion, wherein the drive wheel is a friction wheel and interacts with a pressing device in such a way that the pressing device generates a force which presses the friction wheel onto the segment with the result that the friction wheel can apply a drive torque to the segment through friction, wherein a torque support for supporting an opposing torque to the drive torque generated by the friction wheel 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.
1. A mobile rotary drive for a wind rotor of a wind power plant comprising a frame, a drive wheel that drives a segment of a rotor shaft of the wind power plant, a drive set that drives the drive wheel in rotation as a drive pinion and a torque support,
wherein the drive wheel comprises a friction wheel and that interacts with a contact pressure device such that the contact pressure device produces a force pressing the friction wheel onto the segment resulting in the friction wheel applying a drive torque to the segment through friction,
wherein the torque support supports a countertorque to the drive torque produced by the friction wheel.
2. The mobile rotary drive of claim 1 , wherein the drive set comprises a drive motor.
3. The mobile rotary drive of claim 1 , wherein the drive set has a connection for a separate drive mechanism.
4. The mobile rotary drive as claimed in claim 3 , wherein
the connection comprises a push-fit coupling for the separate drive mechanism.
5. The mobile rotary drive of claim 4 , wherein the separate drive mechanism comprises a wrench or a power tool.
6. The mobile rotary drive of claim 1 , wherein the contact pressure device has a load spring with an adjustable preloading device.
7. The mobile rotary drive of claim 6 , wherein the adjustable preloading device has a plurality of preset load levels for various wind power plants.
8. The mobile rotary drive of claim 1 , wherein the friction wheel is arranged on a rocker which is held pivotably on the frame.
9. The mobile rotary drive of claim 8 , wherein the rocker has a link for connection to the contact pressure device and a lever arm of the link is greater than a lever arm of the friction wheel on the rocker.
10. The mobile rotary drive of claim 1 , wherein the torque support comprises a support plate.
11. The mobile rotary drive of claim 1 , wherein the torque support comprises a quick-action connector to a fixed device of the wind power plant.
12. The mobile rotary drive of claim 11 , wherein the quick-action connector comprises a pair of locking pins.
13. The mobile rotary drive of claim 1 , wherein the torque support comprises a handle.
14. The mobile rotary drive of claim 5 , wherein the separate drive mechanism comprises a cordless screwdriver.
15. The mobile rotary drive of claim 11 , wherein the fixed device comprises a brake caliper.
