Abstract

To facilitate transport and assembly during the erecting of wind power plants, a two-part base frame is proposed for the azimuthal adjustment of the gondola on the tower of the wind power plant, the lower part of which 16 has the azimuthal drive device 23 and the upper part 6 of which has the drive train 1, 2, 12, 13, 14. Both parts are pre-assembled at the factory, set onto the tower, and screwed tight onto each other at their connection point 15.

Independent Claims | See all claims (18)

1. 1. An apparatus, comprising: A base frame for the arrangement of a drive train, which is driven by a wind-driven rotor of a wind power plant, on the tower of the wind power plant on which the base frame is affixed with an essentially horizontal orientation of the rotor axis so that it can rotate azimuthally around the essentially vertical axis of the tower and is constructed from a discrete upper part that carries the drive train and a discrete lower part that has an azimuthal drive device that is attachably joined with the upper part at a connection point, wherein the lower part provides for azimuthal rotation around the essentially vertical axis of the tower, wherein the connection point extends along an essentially horizontal cross-section that has a larger dimension in the direction of the rotor axis than in the direction perpendicular to that.
2. 13. An apparatus, comprising: A base frame for the arrangement of a drive train, which is driven by a wind-driven rotor of a wind power plant, on the tower of the wind power plant on which the base frame is affixed with an essentially horizontal orientation of the rotor axis so that it can rotate azimuthally around the essentially vertical axis of the tower and is constructed from a discrete upper part that carries the drive train and a discrete lower part that has an azimuthal drive device that is attachably joined with the upper part at a connection point, wherein the lower part provides for azimuthal rotation around the essentially vertical axis of the tower, wherein the connection point extends along an essentially horizontal cross-section that has a larger dimension in the direction of the rotor axis than in the direction perpendicular to that, wherein the base frame has a hollow body that is radially limited in relation to the tower axis by an essentially closed wall, whereby the cross-sections of this hollow body have, in its lower end area that borders on the upper end of the tower, a circular contour that, for the cross-sections placed above it axially, makes a transition into a contour that is elongated in the direction of the rotor axis, and the connection point is arranged in the area of its elongated contours, wherein the elongated contours in the area of the connection point are constructed so that they are symmetrical to the rotor axis and have, at their end area that faces away from the rotor, a first section that extends crosswise to the rotor axis and is bent at its ends in the direction to the end area that faces the rotor, a second section that is located at its end area that faces the rotor and is bent towards the end area that faces away, and two side sections that connect the first section to the second section.
3. 15. A base frame for the arrangement of a drive train, which is driven by a wind-driven rotor of a wind power plant, on the tower of the wind power plant on which the base frame is affixed with an essentially horizontal orientation of the rotor axis so that it can rotate azimuthally around the essentially vertical axis of the tower and is constructed from a discrete upper part that carries the drive train and a discrete lower part that has an azimuthal drive device that is attachably joined with the upper part at a connection point, wherein the lower part provides for azimuthal rotation around the essentially vertical axis of the tower, wherein the connection point extends along an essentially horizontal cross-section that has a larger dimension in the direction of the rotor axis than in the direction perpendicular to that, wherein the lower part has, on its lower end area that borders the upper end of the tower, a flange directed radially to the inside, on which at least one servomotor of the azimuthal drive device is arranged with the drive axis parallel to the tower axis and a pinion gear that is arranged rotationally fixed on the drive axis for combing mesh into an inner crown gear that is affixed on the upper end of the tower coaxially to the tower axis.
