Description

Technical Field

[0001] The utility model belongs to the technical field of hangers for pickling of steel pipes, in particular to a hanger for pickling of steel pipes. Background Art

[0002] During the production, storage and transportation of steel pipes, scale and rust are easily formed on the surface. Pickling can effectively remove these impurities and make the surface of the steel pipe clean.

[0003] After the existing steel pipes are pickled in the pickling tank, it is not convenient for personnel to take them out completely. Generally, the steel pipes in the pickling tank are taken out by hooks and slings. During the removal process, dangerous situations such as shaking, tilting and sliding may occur, which poses certain hidden dangers to the safety of the staff. In view of this, we propose a steel pipe pickling sling. Utility Model Content

At this time, several steel pipe bodies will be located between several round rods, and several steel pipe bodies will be located above several rotating plates. Then, the staff starts the crane again, so that the crane drives the two guide rods to move upward, and then the top plate will move upward, the top plate will drive the support frame to move upward, the support frame will drive several round rods to move upward, the round rod will drive the rotating plate to move upward, and several rotating plates will contact the bottom of several steel pipe bodies and drive them to move upward, thereby taking several steel pipe bodies out of the pickling tank.
