[0002] During construction, steel bars are needed to erect steel frames, which are usually used in conjunction with concrete. On the construction site, the steel bars are easily rusted due to long-term oxidation and contact with rainwater outside, so rust removal equipment is needed to remove the rust.

The utility model relates to the technical field of steel bar rust removal.

[0004] The rust removal device in this patent has the disadvantage of low efficiency when used: specifically, in this patent, a hydraulic rod drives an arc-shaped clamp to clamp the steel bar and then remove the rust from it. However, the steel bars used in construction are generally longer, so in this patent, it is necessary to manually control the lifting and lowering of the hydraulic rod repeatedly, and then control the position of the steel bar (push the rust-removed area on the steel bar to allow the unrusted area to enter the top of the rust removal component) in order to achieve rust removal. This will result in a low efficiency problem. Utility Model Content
