Description

Technical Field

[0001] The present invention relates to the field of steel pipes, and particularly to a hoisting device for pickling steel pipes. Background Art

[0002] The steel pipe pickling production line is a pickling process for rust removal and washing of stainless steel or scrap steel for recycling. The pickling solution for the pickling process is generally a mixture of multiple acids, mainly sulfuric acid, nitric acid, hydrofluoric acid, etc. Before pickling, it is necessary to first bind and hoist. Usually, ropes are used for binding, and the motor drives the ropes to tighten, and then it is hoisted into the pickling pool by a traveling crane to start pickling. However, the existing hoisting machines can only hoist the steel pipes back and forth and do not have other functions. When the steel pipes enter the cleaning pool after being pickled in the pickling pool, the pickling solution remaining in the steel pipes will be brought into the cleaning pool, polluting the pool water, so that the cleaning pool needs to be frequently replaced. Therefore, it is very important to have a hoisting device that can pour out the pickling solution remaining in the steel pipes. Summary of the Invention
