[0001] The present application relates to the technical field of petrochemical container processing supporting equipment, and in particular to a petrochemical container bottom welding tool. Background Art

[0002] Petrochemical containers need to be welded during the production process, and the welding process is relatively troublesome. Since the internal compartment structures of some tanks are often unevenly distributed, the center of gravity will shift after rotation, which will lead to the risk of overturning. Therefore, for the bottom welding, the existing operation method requires the container to be lifted and then supported on a higher support seat for welding operations. There are also some cases where a lift or lifting platform is used to lift the container, but this makes it difficult to place operating equipment such as welding machines, and a temporary support platform needs to be set up. In addition, since the volume, size, and placement form of the produced pressure vessels are often different, some larger containers are inconvenient to move to the lifting platform. Therefore, it is necessary to improve the existing pressure vessel bottom welding tooling structure to solve these problems. Summary of the invention

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principle of the existing petrochemical container bottom welding tooling is first introduced.

[0021] The existing petrochemical container bottom welding process is divided into horizontal and vertical. In the production process, the inside of the tank is welded first, and then the external structure of the tank is welded. During the construction process, some welding processes that require the bottom are encountered. The container needs to be lifted and the supporting structure is replaced, or the container is lifted by a front jack or other structure. This operation has the risk of tipping over and poses certain safety hazards. It is not practical for small factories. Therefore, it is necessary to set up a petrochemical container bottom welding tool to solve these problems.

The diameter of the container body 20 is large, and the connecting shaft 8 connected to the support frame 7 can support the container body 20 through the support roller 9, which is convenient for adjusting the angle during welding and reducing indentation and wear. The set connecting sleeve 10 can connect the support bar 11 so that it can move on the support plate 2, and is used to connect components such as welding equipment, reduce the use of supporting equipment, etc. and improve convenience. The set support legs 12 can increase the supporting strength of the support bar 11 to ensure its firmness.
