Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for hot-dip galvanizing production, specifically a steel lifting device for hot-dip galvanizing production. Background Technology

[0002] The steel lifting device used in hot-dip galvanizing production is mainly used to control the lifting of steel parts to be immersed in galvanized solution. Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection, mainly used in metal structures across various industries. It involves immersing rust-removed steel parts in molten zinc at approximately 500°C, causing a zinc layer to adhere to the surface of the steel components, thus achieving corrosion protection. However, currently available steel lifting devices for hot-dip galvanizing production are mostly installed at the top of the equipment, resulting in high manufacturing costs, inconvenient operation, low efficiency, and complex structures; therefore, they do not meet current usage requirements.

[0003] While the steel lifting device for hot-dip galvanizing production disclosed in authorization announcement number CN 218026291 U3 achieves the following: during operation, the hanging fixture on the transverse support rod is moved to the outside of the hot-dip galvanizing tank by rotating the longitudinal column, the steel parts are hung on the hanging fixture, and then the steel parts on the hanging fixture are moved to the top of the hot-dip galvanizing tank. The lifting drive mechanism then drives the sliding block, transverse support rod, hanging fixture, and steel parts to descend into the hot-dip galvanizing tank for galvanizing treatment. The entire device has a simple structure, low production cost, is convenient for workers to use, improves work efficiency, and has low manufacturing cost and strong practicality. However, it does not solve the problem of the cumbersome workpiece movement during existing galvanizing operations. Therefore, we propose a steel lifting device for hot-dip galvanizing production.
