For example, the publication (announcement) number: CN220567076U discloses a liquefied natural gas storage and transportation device. By setting a first protective plate and a second protective plate, the liquefied natural gas tank can be protected from side collision and buffering. However, there are still some shortcomings: the natural gas tank is very troublesome to load and unload. When the vehicle is very high, it needs to be loaded onto the vehicle with the help of lifting equipment, which is very laborious. In addition, the natural gas tank lacks support after unloading. Therefore, improvements are needed. Utility Model Content

A worm 12 is provided at the output end of the motor 11 and is meshed with the worm gear 10. The folding support device 5 is symmetrically provided with two groups on both sides of the natural gas tank 1. The natural gas tank 1 can be supported by rotating the hydraulic cylinder 8 to a vertical state, so that the transport vehicle can be inserted from the bottom of the natural gas tank 1 to facilitate loading and unloading.

[0021] like Figure 1-2 The rotating device 4 includes a rotating shaft 13, which rotates in the fixed plate 2. The lower end of the rotating shaft 13 is fixedly connected to the slot plate 3.
