The aerial transportation vehicle includes a lifting vehicle frame, which includes an upper vehicle frame, a lower vehicle frame, a lifting assembly, and a locking device. The lower vehicle frame and the upper vehicle frame can move close to or away from each other by operating the lifting assembly. The lower vehicle frame and the upper vehicle frame close to each other can be locked together by operating the locking device. The method includes: the aerial transportation vehicle free of load running into position and stopping so that the container is located directly below the aerial transportation vehicle; operating the lifting assembly to separate the upper vehicle frame and the lower vehicle frame, and lower the lower vehicle frame to a preset height; completing the locking of the lower vehicle frame and the container; operating the lifting assembly, so that the lower vehicle frame and the container rise as a whole; operating the locking device to lock the upper vehicle frame and the lower vehicle frame together; and the aerial transportation vehicle being started for transportation after the container assembly process is completed.

(60) In some embodiments of the disclosure, the specific steps of lifting a container by the aerial transportation vehicle provided by the disclosure may comprise:

(61) the non-loaded aerial transportation vehicle free of load running into position and stopping, at which time the container is located directly below the vehicle.fwdarw.operating the lifting assembly so that the upper vehicle frame and the lower vehicle frame are separated.fwdarw.operating the lifting assembly, so that the lower vehicle frame is lowered down.fwdarw.opening the container anti-falling device on the lower vehicle frame.fwdarw.operating the locking device between the lower vehicle frame and the container to complete the locking of the lower vehicle frame and the container.fwdarw.operating the lifting assembly so that the lower vehicle frame and the container rise as a whole.fwdarw.the container anti-falling device on the lower container being shrunk to hold the container.fwdarw.operating the lifting assembly and the locking device, so that the upper vehicle frame and the lower vehicle frame are locked.fwdarw.the aerial transportation vehicle being started for transportation after the assembly of the container is completed. For the unloading process, contrary operations will be done.

(62) In summary, the aerial transportation vehicle provided by the disclosure can achieve assembly and connection of the aerial transportation vehicle with the container through its own devices, which is simple in operation, and has high automation level and good practicability.

(63) The embodiments described above are preferred embodiments of the disclosure, which are only used to facilitate the description of the disclosure rather than limiting the disclosure in any form. Any equivalent embodiments obtained by those of ordinary skill in the art by partially modifying or changing the embodiments of the disclosure based on the content of the disclosure without departing from the technical features of the disclosure all fall within the scope of the disclosure.
