[0029] The vehicle body 1 is a vehicle body 1 provided with wheels, and the entire device can be moved to a designated position according to requirements through the wheels. The sliding component sliding table 3 can slide from one end of the rotating lifting platform 2 to the other end, so that the power battery can be transported to the aircraft storage position according to requirements, or the power battery disassembled from the aircraft can be recycled. The sliding drive component is a power source, which can drive the sliding component to drive the sliding table 3 to linearly displace. When the sliding table 3 is displaced to the end, the sliding guide component can guide the battery into the aircraft or guide the battery on the aircraft onto the sliding table 3. The lifting component can be lifted according to the position of the power battery installed on the aircraft. The rotating component can rotate the rotating lifting platform 2 by 180°, so that the entire device only needs to be aligned with the battery installation position of the aircraft once, and the battery can be transported into the aircraft or the battery in the aircraft can be recycled.

[0030] As shown in Figures 1-2 , the sliding component includes sliding rails 4 and sliding blocks 5. The specific number of the sliding rails 4 is two, and the two sliding rails 4 are arranged on the upper surface of the rotating lifting platform 2 and symmetrically distributed about the center of the sliding table 3. The specific number of the sliding blocks 5 is several, and the sliding blocks 5 are respectively slidably connected to the two sliding rails 4, and the upper surfaces of the sliding blocks 5 are bolted to the sliding table 3.

[0031] The symmetrical design of the double sliding rails 4 can keep the sliding table 3 relatively stable during movement and prevent shaking and deviation. The sliding blocks 5 enable the sliding table 3 to linearly displace. The multiple sliding blocks 5 enable the sliding table 3 to have a larger load capacity.

[0032] As shown in Figures 1-3 , the sliding drive component includes a drive motor 6, an output gear 7, an output connecting shaft, an output rack 8, and a drive mounting plate 9.

The lifting cylinder 15 serves as a power source to push the telescopic connecting plate 16 to rise and fall. The rising and falling of the telescopic connecting plate 16 can drive the telescopic rod 15 to rise and fall.

[0038] like Figures 5-6 The rotating assembly includes a rotary motor 18, a drive pulley 19, a driven pulley 20, a synchronous belt 21, a rotating connecting rod 22, and a rotating mounting plate 23.
