[0002] The building steel structure is a main structure of a building which is combined by steel members through welding, bolt connection and the like, using steel as a main building material. The steel structural member refers to a steel structural combined member which can bear and transfer load, and is formed by cold bending or welding or connecting through connecting pieces, using steel plates, angle steels, channel steels, I-beams, steel pipes, H-shaped steels and the like.
[0003] During the production and storage of the steel structural member, rusting phenomenon is prone to occur on the surface of the steel. In order to ensure the performance and aesthetics of the steel structure before being put into use or being coated, effective pretreatment measures must be implemented on the surface, and the rust removal process is particularly crucial. The rust removal quality is not only directly related to the safety and durability of the subsequent use of the steel structure, but also is one of the important factors for determining the protection effectiveness of the coating and prolonging the service life. At present, for the rust removal of large steel structural members, handheld tools such as electric grinders or hand-held wire brushes are usually used. The electric grinder uses a high-speed rotating grinding wheel to strongly grind the rust layer on the metal surface, and is suitable for removing thick rust; and the hand-held wire brush is mainly used for removing light to moderate rust, and is particularly suitable for treating details such as edges and corners. However, these methods not only increase the labor intensity and labor cost, but also lead to unstable rust removal effect due to the difference in skill level of the operators, and it is difficult to ensure uniform high-quality standards.
[0004] Therefore, it is necessary to design a rust removal device suitable for the production site, which meets the production and use requirements and is convenient for on-site operation and application. SUMMARY

A guide wheel unit 4 is installed at the front end of the moving direction of the moving carrier 2 and on both sides of the steel structure 1, which is used for guiding and limiting the moving carrier 2; a positioning hole is arranged at the top of the front end of the moving direction of the moving carrier 2. A control box 303 is also installed on the top of the moving carrier 2, which is used for controlling the mechanical arm unit 3. The two guide wheel units 4 are the same in structure, each comprising a support plate 401 arranged horizontally and a guide wheel 404, and at least two pin columns 402 are arranged at one end of the bottom of the support plate 401 along the length direction of the support plate 401, which are used for cooperating with the corresponding positioning hole to adjust the position of the guide wheel unit 4; in use, the pin columns 402 are inserted into the corresponding positioning hole 208; the other end of the bottom of the support plate 401 is rotationally connected with the guide wheel 404 through a fixing shaft 403, and in use, the guide wheel 404 is in contact with the steel structure 1.
[0028] In embodiment 1, the positioning holes are divided into two groups, each group of positioning holes corresponds to a guide wheel unit 4, each group of positioning holes comprises two rows of positioning holes arranged side by side, and the front and rear positioning holes of the two rows of positioning holes are in line with each other; in use, the two pin columns 402 of the guide wheel unit 4 are inserted into the same group of positioning holes, and among the two pin columns 402, the first pin column is inserted into the first row of positioning holes, and the second pin column is inserted into the second row of positioning holes, and the two inserted positioning holes are the two positioning holes with the hole centers in line with each other; the depth of the pin column 402 inserted into the positioning hole satisfies that the guide wheel unit 4 will not overturn.
