Wind turbine base self-locking foldable wedge block device

Abstract

The invention designs a self-locking foldable wedge-shaped cushion block of a wind power generator base, which belongs to the technical field of wind power generators. The wedge includes a base, the elastic support of the generator and the wedge. The wedge includes an upper wedge and a lower wedge. The upper and lower wedges adopt the same structure, and the lower wedge is connected to the base. The upper wedge-shaped pad is connected with the elastic support bottom surface of the generator, and the slope of the upper wedge-shaped pad is placed on the slope of the lower wedge-shaped pad. The self-locking foldable wedge-shaped cushion block of the base of the wind power generating set designed by the present invention has a simple structure, is foldable, and is easy to carry. Phenomenon, improve the reliability of the adjustment; rough adjustment of the number of overlapping pads of the upper and lower wedges can greatly adjust the height of the pads, and fine adjustment of the upper wedge can meet the requirements of small adjustments during use and improve the working speed of adjustment and accuracy.

Description

technical field [0001] The invention belongs to the field of wind power generators, in particular to a base self-locking foldable wedge pad device for supporting and centering a wind power generator. Background technique [0002] Wind turbines are generally installed in the nacelle. During installation, it is necessary to ensure that the rotating shaft of the generator is coaxially connected with the high-speed transmission shaft of the gearbox. Since the adjustment height of the elastic support of the generator is not enough to meet the needs of the installation and adjustment of the wind turbine, after a long-term use of the elastic support of the generator, the vertical adjustment will also be insufficient, so we can only add pads at the bottom of the elastic support or replace it with a new one. support. However, due to the small space in the engine room, it is very inconvenient for the staff to operate in the engine room, and it is difficult to improve work efficiency,...

Problems solved by technology

Since the adjustment height of the elastic support of the generator is not enough to meet the needs of the installation and adjustment of the wind turbine, after a long-term use of the elastic support of the generator, the vertical adjustment will also be insufficient, so we can only add pads at the bottom of the elastic support or replace it with a new one. support

However, due to the small space in the engine room, it is very inconvenient for the staff to operate in the engine room, and it is difficult to improve work efficiency, and the pads used in the installation and maintenance process need to be specially customized, which makes the high-speed transmission of the generator shaft and the gearbox The work of shaft alignment is cumbersome and the maintenance time is long; directly replacing the new elastic support will increase the maintenance cost
