Technical Field

[0001] The utility model relates to the field of steel structure processing, in particular to a steel structure surface galvanizing device. Background Art

[0002] Steel structure refers to a metal building support structure assembled by welding steel materials. It is one of the common structural forms in construction projects.

[0003] In the current existing technology, in order to improve the corrosion resistance of steel structures, people need to plate a layer of zinc on the surface of the steel structures. The galvanizing methods are divided into hot dip galvanizing and cold galvanizing. Cold galvanizing is electroplating. The staff needs to immerse the steel structure into the galvanizing tank through the corresponding clamps so that it is immersed in the electroplating liquid. After that, power is turned on to form a zinc coating on the surface of the steel structure. Then, the steel structure is lifted from the galvanizing tank to complete the galvanizing of the steel structure.

[0004] After the electroplating is completed, there will be electroplating liquid remaining on the surface of the steel structure. In order to facilitate subsequent processing, the staff generally adopts the static dripping method to reduce the residual electroplating liquid. However, the static dripping method requires a long waiting time and is time-consuming and laborious. Therefore, a steel structure surface galvanizing device is proposed to address the above problems. Utility Model Content
