Description

Technical Field

[0001] The utility model relates to the technical field of spherical tank installation, in particular to a spherical tank installation positioning device. Background Art

[0002] Most of the existing spherical tank installations are done by lifting each petal of the spherical tank with a crane, and then manually positioning and installing them one by one. After all the spherical shell plates are assembled into a whole sphere on the foundation, they are welded. During assembly, the values ​​of misalignment, angularity, equatorial horizontal error, maximum and minimum inner diameter difference, etc. should be adjusted to the optimal state to avoid forceful assembly and reduce assembly stress.
