Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a wind turbine main shaft and gearbox shaft tensioning sleeve alignment device. Background Technology

[0002] In wind power generation systems, the alignment accuracy of the connection between the main shaft and the gearbox shaft tensioning sleeve directly affects the operating efficiency and service life of the entire system.

[0003] In traditional methods, the alignment of the main shaft and gearbox shaft expansion sleeves often relies on manual operation of equipment such as hand hoists, with preliminary alignment performed by visual inspection. Coaxiality testing is also done solely by visual inspection, lacking quantitative measurement standards, resulting in low alignment accuracy. Manual adjustment requires precise installation of rotational force values, but alignment accuracy is difficult to control. The structure of the expansion sleeve and its fit with the main shaft and gearbox shaft also affect alignment. Therefore, a wind turbine main shaft and gearbox shaft expansion sleeve alignment device is needed to improve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A wind turbine main shaft and gearbox shaft tensioning sleeve alignment device includes a main body 1, a position adjustment component 2 is provided on the top of the main body 1, and a gearbox component 3 is fixedly connected to the top of the main body 1.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the main body 1 includes a base plate 101, with a sliding groove 105 inside the base plate 101. The position adjustment assembly 2 includes a telescopic rod 201, with a slider 202 fixedly connected to the output end of the telescopic rod 201. A top extension rod 203 is installed on the top of the slider 202, and a disc base 204 is fixedly connected to the output end of the top extension rod 203. A laser measurement centering unit 207 is installed on the top of the disc base 204. The gearbox assembly 3 includes a gearbox body 301, with a reflector 305 installed on the top of the gearbox body 301. Using laser measurement to center the spindle and gearbox shaft tensioning sleeve can provide extremely high measurement accuracy, helping to ensure the precise alignment of the spindle and gearbox shaft, meeting the strict requirements of wind power generation systems for coaxiality. Laser measurement can quickly acquire measurement data, reducing the time spent on manual operation and repeated adjustments, and improving the efficiency of the entire centering process. Laser measurement is a non-contact measurement, not limited by the installation environment of wind power generation equipment. Through laser measurement, the potential risks of manual operation can be reduced, and the safety of the installation process can be improved.

[0029] The slider 202 is disposed inside the slide groove 105 and slides within the slide groove 105. The laser measurement centering unit 207 includes a laser emitter and a receiver. A bearing 205 is installed inside the disk base 204, and a main shaft body 206 is disposed inside the bearing 205. An input rod 302 and an output rod 303 are connected to the gearbox 301. A shaft expansion sleeve body 304 is fixedly connected to the side of the output rod 303. The slider 202 slides inside the slide groove 105 by extending and retracting the telescopic rod 201, thereby adjusting the main shaft inside the bearing 205. The main body 206 can be adjusted to the left and right, while the extension and retraction of the top extension rod 203 can adjust the vertical position of the main body 206. Both the extension rod 201 and the top extension rod 203 have fine-tuning functions, which can achieve extremely precise position adjustment. By controlling the extension and retraction of the extension rod 201 and the top extension rod 203, quantitative position adjustment can be achieved. Compared with traditional manual adjustment, this method can provide more precise control and reduce errors. The extension rod 201 and the top extension rod 203 can achieve automated or semi-automated operation, which reduces the need for manual intervention and improves the convenience of operation.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the base plate 101 has two threaded holes 102 inside. A protective cover 103 is provided on the top of the base plate 101. A threaded rod 104 is provided inside the protective cover 103, extending into the threaded hole 102. A pad 106 is fixedly connected to the bottom of the base plate 101. Four pads 106 are provided. The protective cover 103 covers and protects the shaft expansion sleeve body 304, which can effectively block these impurities and prevent them from entering the expansion sleeve, thereby reducing wear and failure. The protective cover 103 can keep the shaft expansion sleeve clean and avoid poor heat dissipation or other performance degradation problems caused by dust accumulation. The protective cover 103 can prevent operators or maintenance personnel from accidentally contacting the high-speed rotating shaft expansion sleeve during operation, reducing the occurrence of safety accidents.

[0031] The working process of this utility model is as follows: When the centering device for the main shaft of a wind turbine and the gearbox shaft expansion sleeve designed in this scheme is in operation, the laser emitter of the laser measurement centering unit 207 is activated, and a laser beam is emitted to irradiate the reflector plate 305, which will generate reflected light. The receiver receives the reflected light signal and performs an initial measurement based on the position of the laser spot or the distribution of interference fringes. By analyzing the laser signal, the initial positional deviation between the main shaft body 206 and the shaft expansion sleeve body 304 can be detected to determine whether they are in a centered state. Based on the deviation data obtained from the initial measurement, the position of the main shaft body 206 is adjusted by the adjustment mechanism. Specifically, the extension and retraction of the telescopic rod 201 can be used to make the slider 202 slide inside the slide groove 105, thereby adjusting the left and right position of the main shaft body 206 inside the bearing 205. The extension and retraction of the top extension rod 203 can adjust the up and down position of the main shaft body 206. After adjusting the position of the main shaft body 206, laser measurement is performed again to check the centering status after adjustment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
