[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Reference Figures 1 to 3 A connecting device for a low-temperature semi-trailer tank body comprises a bottom plate 10, a receiving plate 2, an arc-shaped web 3 and a plurality of locking devices, wherein the bottom plate 10 is connected to the receiving plate 2, the receiving plate 2 is provided with a plurality of insertion holes 201, the web 3 is provided with a plurality of insertion rods 301, one side of the receiving plate 2 is arc-shaped and abuts against the receiving plate 2, and the insertion rods 301 cooperate with the insertion holes 201, and the locking device is used to fix the bottom plate 10 on the chassis of the low-temperature semi-trailer. In the utility model, when supporting the tank body, the web 3 is first fitted with the outer wall of the tank body and then welded to fix the web 3 on the tank body, and the receiving plate 2 is moved to fit with the web 3, and the bottom plate 10 fits with the chassis of the low-temperature semi-trailer. The locking device fixes the bottom plate 10 on the chassis of the low-temperature semi-trailer, and then fixes the receiving plate 2. The plug rod 301 cooperates with the socket 201 to limit the web 3, and then limit the tank body to prevent it from moving. Since the receiving plate 2 bears the weight of the tank body, when it cracks after long-term use, the bottom plate 10 and the receiving plate 2 can be disassembled together by removing the locking device, and a new bottom plate 10 and receiving plate 2 can be replaced. This structure is convenient for replacement. Specifically, a plurality of support devices are required to support the tank body, and the support devices are arranged on both sides of the tank body.
