[0020] In this technical solution, in the transport state, such as Figure 1 As shown, the hydraulic cylinder 12 is in a retracted state, the slider 11 is located in the groove, and the skid 4 is horizontally arranged on the frame 1 and remains stable under the action of the bottom plate 2 and the fastening device 5, and is towed and transported to the installation site by the tractor head 10. The tractor head 10 and the frame 1 can be conventional trailers or semi-trailers, and their carrying capacity can meet the transportation requirements of the storage tank 3 with the frame size. After reaching the installation site, as shown in FIG. Figure 2 As shown, first, the skid 4 is slid relative to the slider 11, so that the end of the skid 4 away from the tractor head 10 slides out of the frame 1 for a certain distance to meet the turning space requirement of the storage tank 3. Then, the turning device is started, and the hydraulic cylinders 12 on both sides of the slider 11 are synchronously extended to drive the skid 4 to rotate from a horizontal state to a vertical state until the storage tank 3 is stably erected on the ground. Figure 3 In the above process, the tractor head 10 always keeps connected with the vehicle frame 1, and acts as a load-bearing object to maintain the stability of the storage tank 3 during the overturning process.
