After the above operations are completed, each transport trolley 200 moves to the bottom of the extension part 312 of the corresponding corbel 31, and the lifting body 230 of the transport trolley 200 is driven to rise to simultaneously lift the extension part 312 of the corbel 31, so that the entire tire carrier 100 and the tank are raised by 50-200mm, and then the transport trolley 200 is driven to make its driving wheel 220 move along the first guide rail or the second guide rail, and the tire carrier 100 and the tank are moved together to the bottom of the lifting device to land.

[0082] After the lifting operation of the storage tank is completed, the above-mentioned operation of using the driving trolley to move the tire carrier 100 and the storage tank together is repeated, and the storage tank is transferred to another place to free up the space under the lifting device, which is convenient for the subsequent related operations of other storage tanks, and greatly improves the turnover utilization rate of the space resources under the lifting device, and alleviates the problem of shortage of space resources under the lifting device. In addition, for a batch of storage tanks of the same model, after one of the storage tanks is completed, the tire carrier 100 can continue to carry another storage tank until it is completed, so as to realize the repeated use of the tire carrier 100.
