Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, in particular to a rust removal device for a scaffold steel pipe used in construction. Background Art

[0002] In construction, scaffolding is an indispensable and important equipment, especially in high-rise buildings and large-scale construction projects. The safety and stability of scaffolding are crucial to the safety of construction workers. Scaffolding is usually made of steel pipes. However, since steel pipes are exposed to the external environment during use, they are easily corroded by corrosive substances such as moisture, oxygen, and salt in the atmosphere, causing rust on the surface of the steel pipes. Rust not only affects the appearance of the scaffolding, but more importantly, it weakens the strength of the steel pipes, thereby affecting the bearing capacity and safety of the entire scaffolding. Therefore, rust removal of steel pipes has become a vital issue.

[0003] However, as far as the current traditional rust removal devices are concerned, their design structure is relatively simple. Many traditional rust removal devices lack flexible fixing mechanisms and cannot be effectively fixed according to the specific size of the steel pipe. This design defect causes the steel pipe to shake easily during the rust removal process. The instability of the steel pipe not only reduces the rust removal effect, but also increases the danger of operation. Since the steel pipe shakes too much during the rust removal process, it is difficult for the rust removal tool to maintain uniform contact with the surface of the steel pipe, resulting in incomplete rust removal, which may leave rust spots or produce uneven grinding effects. This unevenness not only affects the appearance of the steel pipe, but may also lead to accelerated corrosion in local areas. Summary of the invention

[0004] In view of this, the present invention provides a rust removal device for scaffold steel pipes for construction, which has a limiting mechanism and an auxiliary mechanism as well as a driving roller and a driven roller, so that the rust removal device can more easily fix and remove rust on the steel pipe according to the specific size of the steel pipe, which is beneficial to prevent the steel pipe from shaking significantly during rust removal, improves the rust removal effect on the steel pipe, and enables the steel pipe to follow the rotation of the driving roller while moving forward, which is beneficial to improving the rust removal efficiency.
