[0042] The specific structure of the gear box shaft dismounting device in the embodiment will be described below.

[0043] As shown in the drawings, Figure 1 and Figure 2The gear box shaft part dismounting device in the embodiment is used for dismounting operation of the upper shaft part of the gear box, and especially for the gear box in the wind turbine generator set. The gear box shaft part dismounting device in the embodiment can quickly dismount the high-speed shaft system, has universality, and can effectively improve the operation efficiency and dismounting efficiency of the shaft part replacement.

The gear box includes a box body 200 and a high-speed shaft 100.

[0044] Optionally, the hoisting assembly 10 is slidingly arranged at one end of the cross beam 20, and is used for hoisting and lowering of the whole gear box shaft part dismounting device. In this way, the device can be moved to the high-speed shaft 100, and the high-speed shaft 100 can be simultaneously hoisted away or installed on the box body 200 with the device. Meanwhile, the center of gravity of the whole gear box shaft part dismounting device can be adjusted to ensure the stability of hoisting. Specifically, the other end of the cross beam 20 is rotationally connected to the connecting beam 30, and can be locked at any position. In this way, the cross beam 20 can be rotationally adjusted at a corresponding angle according to actual needs. Further, the vertical beam 40 is perpendicularly and adjustably connected to the connecting beam 30. In this way, the distance between the vertical beam 40 and the cross beam 20 can be adjusted to adapt to high-speed shafts 100 of different heights, and the application range is expanded. Optionally, the sleeve assembly 50 and the pressing plate assembly 60 are arranged on opposite sides of the vertical beam 40, and the sleeve assembly 50 can be sleeved on the outside of the high-speed shaft 100 of the gear box. In this way, the high-speed shaft 100 can be locked to ensure the stability during the dismounting process. Further, the clamping size of the sleeve assembly 50 is adjustable, and can be applied to high-speed shafts 100 of different sizes, further expanding the application range.

For example, when the driving assembly 70 drives the locking stud 80 to move away from the gear box, the pressing plate assembly 60 is pressed outward to the box body 200 of the gear box, so that the pressing plate assembly 60 can be stationary relative to the box body 200, while the vertical beam 40, the sleeve assembly 50 and the high-speed shaft 100 connected with the locking stud 80 will be simultaneously moved outward synchronously with the locking stud 80, so that the connecting beam 30 connected with the vertical beam 40 and the high-speed shaft 100 sleeved with the sleeve assembly 50 are synchronously moved, at the same time, the horizontal beam 20 and the hoisting assembly 10 are synchronously moved away from the box body 200, and the hoisting rope slightly swings, thereby the high-speed shaft 100 is taken out under the stable hoisting of the hoisting equipment, and the gear box shaft part disassembly and assembly device and the high-speed shaft 100 are integrally moved to other positions under the hoisting of the hoisting equipment, and the disassembly work is completed.

For example, the jack 71 in the embodiment is arranged as a hydraulic jack, and other types of jacks can also be selected in other embodiments, which will not be described herein. Specifically, when the jack 71 presses the pad plate 72 or the universal pressing plate 61, the locking stud 80 can move in the through hole of the universal pressing plate 61 and drive the high-speed shaft 100, the vertical beam 40, the sleeve assembly 50, the high-speed shaft 100, the connecting beam 30, the cross beam 20 and the hoisting assembly 10 to move relative to the pressing plate assembly 60, at which time the hoisting rope slightly swings until the high-speed shaft 100 is taken out. For example, when the driving end of the jack 71 presses the universal pressing plate 61, the jack 71 can move away from the universal pressing plate 61 during the driving process, and the bottom of the jack 71 can drive the pad plate 72, the locking nut 73 and the locking stud 80 to move synchronously, thereby realizing the operation process of moving the locking stud 80 away from the high-speed shaft 100 to realize disassembly, and conversely, the installation process of the high-speed shaft 100 can be realized. In other embodiments, the operation mode and direction of the jack 71 can also be selected as needed.

[0055] Working process: when the disassembly operation of the shaft part is performed, first, the hoisting rope of the crane is hooked to the connecting lifting ring 11, so that the gear box shaft part dismounting device as a whole can be moved and transported until the sleeve assembly 50 can be sleeved on the outside of the high-speed shaft 100, and the locking stud 80 can be screwed in the central threaded hole of the high-speed shaft 100. Then, the position of the fixing stud 62 on the outside of the box body 200 is adjusted, and after ensuring the stable support, the jack 71 is slowly opened, the locking stud 80 is driven to move away from the high-speed shaft 100 under the action of the jack 71, and the high-speed shaft 100, the cross beam 20, the connecting beam 30, the vertical beam 40 and the hoisting assembly 10 can all move outward. At this time, the hoisting rope slightly swings, and after the high-speed shaft 100 is pulled out of the bearing hole, the jack 71 is closed and the crane is started, so that the high-speed shaft 100 connected with the gear box shaft part dismounting device as a whole moves outward, until the high-speed shaft 100 is pulled out for transfer, and the disassembly operation is completed. Conversely, the installation operation of the shaft part can be realized.
