[0028] like Figure 1 As shown, the moving device 20 includes a supporting upper frame 6, a moving base frame 7 arranged at the lower side of the supporting upper frame 6, a lifting mechanism 8 transmission-connected between the supporting upper frame 6 and the moving base frame 7, and a translation mechanism 9 transmission-connected to the moving base frame 7. The fuselage 1, the drive box 3 and the lifting bracket 5 are all fixedly installed on the top of the supporting upper frame 6. The lifting mechanism 8 is used to drive the supporting upper frame 6 to move in the up and down directions relative to the moving base frame 7. The translation mechanism 9 is used to drive the moving base frame 7 to drive the supporting upper frame 6 to move in the front and rear directions.

[0029] like Figure 1 , 2 As shown in Figures 3 and 6, the lifting mechanism 8 includes a pair of lifting components 81 arranged relatively front to back, each lifting component 81 includes a pair of worm gear elevators 811 arranged relatively left to right, a transmission shaft 812 transmission-connected between the pair of worm gear elevators 811, and a lifting motor 813 transmission-connected to one of the worm gear elevators 811, the lifting motor 813 is used to drive the worm gear elevator 811 to lift and lower the supporting frame 6; when the lifting motor 813 is driven, the transmission shaft 812 enables the pair of worm gear elevators 811 transmission-connected to perform lifting actions synchronously, so as to ensure that the supporting frame 6 remains parallel to the movable base frame 7 and is lifted and lowered smoothly.

[0030] Each lifting assembly 81 also includes a pair of guide columns 814 arranged opposite to each other on the left and right. One guide column 814 is configured for one worm gear lift 811.
