DETAILED DESCRIPTION

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a yaw drive disassembly device for a wind turbine generator set includes a slide rail 1 fixed to the inner side of the top of a nacelle, a slide seat 2 slidably connected to the slide rail 1, a winch 3 fixed to the slide seat 2, four claws 4 arranged below the winch 3, and used to drive the four claws 4 to move closer to or away from the adopted driving component, a steel wire rope 5 is wound around the output end of the winch 3, one end of the steel wire rope 5 extends to the bottom of the winch 3 and is connected to a cylindrical lifting seat 6, and the driving component is installed on the lifting seat 6.

[0018] When in use, the four claws 4 are driven by the driving assembly to approach each other to clamp the yaw motor or yaw reducer, the winch 3 drives the lifting seat 6 to rise through the wire rope 5 to lift the yaw motor or yaw reducer, and the yaw motor or yaw reducer can be loaded and unloaded by pushing the slide seat 2 to slide along the slide rail 1; the utility model does not require the cooperation of multiple people to complete the installation and disassembly, the loading and unloading process is more time-saving and labor-saving, and it can also avoid slipping and injuring people during the loading and unloading process, and it is safer and more reliable to use.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a connecting seat 51 is fixed to one end of the steel wire rope 5, and four rope buckles 61 are arranged on the lifting seat 6. The four rope buckles 61 are respectively close to the outer edge of the lifting seat 6 and are arranged at equal angles with the axis of the lifting seat 6 as the center. The rope buckle 61 is connected to the connecting seat 51 through a connecting rope 52. In this embodiment, the steel wire rope 5 is connected to the lifting seat 6 by connecting the rope buckle 61 and the connecting seat 51 through four connecting ropes 52, and the connection force is more uniform.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a cylindrical cavity is provided in the lifting seat 6; the driving assembly includes a driving motor 71 fixed on the lifting seat 6, a rotating disk 72 rotatably connected in the cavity, the driving motor 71 is used to drive the rotating disk 72 to rotate, four spiral guide grooves 721 are provided on the rotating disk 72, which are spirally and divergently distributed with the axis of the lifting seat 6 as the center, and four guide straight grooves 62 are provided at the bottom of the lifting seat 6, which are divergently distributed with the axis of the lifting seat 6 as the center. A slider 73 is slidably connected in the spiral guide groove 721. One end of the slider 73 passes through the guide straight groove 62 and is connected to the claw 4. The slider 73 is slidably connected to the guide straight groove 62. In this embodiment, during the process of the driving motor 71 driving the rotating disk 72 to rotate, the rotating disk 72 drives the slider 73 to slide along the spiral guide groove 721, and at the same time the slider 73 slides along the guide straight groove 62, so that the multiple sliders 73 approach or move away from each other, thereby making the four claws 4 approach or move away from each other.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the claw 4 includes a connecting rod 41 with the top end fixed on the slider 73, and an arc-shaped hoop 42 fixed at the bottom end of the connecting rod 41. The four arc-shaped hoops 42 surround to form a circular hoop. In this embodiment, as the four sliders 73 approach each other, the four arc-shaped hoops 42 approach each other, and the radius of the circular hoop gradually decreases, clamping the yaw motor or the yaw reducer tightly to avoid the situation of slipping and hurting people during loading, unloading and handling.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the connecting rod 41 is in a U shape, and the slider 73 and the arc-shaped hoop 42 are respectively connected to the ends of the upper and lower horizontal parts of the connecting rod 41. In this embodiment, the U-shaped connecting rod 41 can avoid the large outer diameter part on the yaw motor and the yaw reducer, so that the arc-shaped hoop 42 can clamp the small outer diameter part on the yaw motor and the yaw reducer, further preventing the yaw motor or the yaw reducer from slipping and hurting people during loading, unloading and handling.
