Abstract
A system for adjusting and/or restraining a gearbox of a wind turbine includes a base component fixed to the gearbox and a vertical displacement device configured atop the base component. As such, the vertical displacement device is configured to apply a force to the base component. Accordingly, by lifting the vertical displacement device, a downward vertical force is applied to the base component so as to adjust (i.e. lower) the gearbox.
Claims18
A system for adjusting a height of a gearbox of a wind turbine, the system comprising:
- a base component fixed to the gearbox;
- and,
- a vertical displacement device comprising at least one hydraulic cylinder configured atop the base component, a lifting beam configured atop the at least one hydraulic cylinder, and a sling system secured to the lifting beam and a fixed location of the wind turbine,
- wherein, by raising the at least one hydraulic cylinder, the lifting beam is pushed upward such that a downward vertical force is applied to the base component via the sling system so as to lower the gearbox.
A gearbox restraint system for a gearbox of a wind turbine, the gearbox restraint system comprising:
- a base component fixed to the gearbox;
- and,
- a restraint device comprising at least one hydraulic cylinder configured atop the base component, the restraint device configured to restrain the gearbox by applying a force to the base component, a lifting beam configured atop the hydraulic cylinder, and a sling system secured between the lifting beam and a fixed location of the wind turbine;
- wherein, by raising the at least one hydraulic cylinder, the lifting beam is pushed upward such that a force is applied to the base component via the sling system so as to restrain the gearbox.
