Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing device for producing power tower parts. Background Art

[0002] In the design and production process of power tower parts, considering their need for a long service life, not only the structural strength must be high enough, but also they need to be resistant to environmental corrosion. Therefore, after the power tower parts are processed and formed, they need to be hot-dip galvanized to form a galvanized layer on the surface to reduce the corrosion of the power tower parts and protect them.

[0003] The production and processing of power tower parts in the existing technology involves a hot-dip galvanizing process. The tower support pipe is placed in a galvanizing pool through a lifting mechanism, so that the outer surface of the pipe is galvanized. The pipe is controlled to rise and separate from the zinc liquid, and the finished pipe is obtained after cooling. During the process, the contact position between the pipe and the support mechanism may not be coated with zinc, that is, the contact point of the support mechanism will block part of the outer surface of the pipe.

[0004] For example, the document with publication number CN113684436A discloses a hot-dip galvanizing device for the production of power tower parts. The invention realizes galvanizing by immersing the pipe in zinc water, and the pipe rotates to a certain extent during the process to ensure that the outer wall of the pipe is contacted by the zinc liquid, avoiding the problem that part of the outer surface of the pipe is not contacted with the zinc liquid. The function is stable and powerful.
