Description

Technical Field

[0001] The utility model relates to the technical field of spherical tank shell processing equipment, in particular to a fixing component for spherical tank shell processing. Background Art

[0002] A spherical tank is a spherical container used to store liquids or gases. It is commonly used in the petrochemical, chemical engineering and energy industries. During the production process of a spherical tank, the shell needs to be docked with a fixing assembly to facilitate subsequent welding and assembly. The existing fixing assemblies used for processing the shell of a spherical tank still have the following problems during use:

[0003] First, the existing fixing assembly for processing the spherical tank shell cannot stably clamp the spherical tank shell during use, which easily causes the spherical tank shell to shake during the docking process, affecting the docking accuracy;

[0004] Secondly, the existing fixing assembly for processing the spherical tank shell is not convenient for docking the spherical tank shell after fixing it due to its heavy weight, which affects the assembly efficiency. Therefore, we propose a fixing assembly for processing the spherical tank shell. Utility Model Content
