[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a grabbing mechanism for fan hub spraying includes a door-shaped frame 1 and a winch 2 arranged at the upper end of the door-shaped frame 1, a lifting plate 3 is connected to the end of the wire rope of the winch 2, a guide mechanism for guiding the lifting plate 3 to rise and fall is arranged between the lifting plate 3 and the upper end of the door-shaped frame 1, and a connecting mechanism connected to the fan hub is arranged at the lower end of the lifting plate 3. When the fan hub is lifted, the lifting plate 3 descends, and under the guiding action of the guide mechanism, the connecting mechanism can be accurately connected to the fan hub, and during the movement, the fan hub will not shake, and the safety is good.

[0020] like Figure 1As shown, the guide mechanism includes a guide rod 4 arranged at the upper end of the lifting plate 3, and a guide sleeve 5 is provided at the upper end of the door-shaped frame 1 to cooperate with the guide rod 4. Through the cooperation between the guide rod 4 and the guide sleeve 5, when the lifting plate 3 descends, the connecting mechanism can accurately hook the fan hub, and during the movement, the fan hub is positioned without shaking.
