Lifting device for steel pipe pickling

Abstract

The invention discloses a lifting device for steel pipe pickling. The problems that water in other pools needs to be frequently replaced and the cost is increased due to the fact that when existing steel pipes enter the other pools after being pickled, a small amount of pickling liquid is brought to the water in other pools and the water in other pools are contaminated are solved. The lifting device comprises a loading part, an abutting block, supporting plates, a lifting part, a boom, meshed plates and a pickling part; the loading part is provided with a base, and the steel pipes can roll infrom the right side of the base; the abutting block is in an inverted triangle shape and located at the middle position of the left end of the base; the supporting plates are located on both sides ofthe base; the lifting part is provided with a long plate, and the long plate is used for being fitted to the tops of the steel pipes; the boom is located above the long plate; the meshed plates are arranged at both ends of the long plate, and the meshed plates are used for flipping down to abut against the two ends of the steel pipes; and the pickling part is arranged in front of the loading part,and the pickling part is internally provided with a pickling pool, a washing pool, a phosphating pool and a saponification pool. The lifting device has the beneficial effects of not polluting the water in other pools and saving costs.

Description

Technical field [0001] The invention relates to the field of steel pipes, in particular to a lifting device for steel pipe pickling. Background technique [0002] The steel pipe pickling production line is a pickling process for rust removal and washing of stainless steel or scrap steel to rebuild. The pickling solution of the pickling process is generally a mixture of various acids, mainly sulfuric acid, nitric acid, and hydrofluoric acid. Before washing, it must be bundled and lifted. Usually, ropes are used for binding. The motor drives the ropes to tighten, and then they are lifted by crane to the pickling tank to start pickling. However, existing lifting machines can only lift steel pipes back and forth. , Does not have other functions. When the steel pipe enters the pickling tank and enters the cleaning tank after pickling, the pickling liquid left in the steel pipe will be brought into the cleaning tank, polluting the pool water, making the cleaning tank frequent replaceme...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a hoisting device for pickling steel pipes, so as to solve the problem that when the existing steel pipes are pickled and enter other pools, some pickling liquid will pollute other pool water, resulting in frequent replacement of other pool water and increasing costs.
