[0002] As an important part of modern architecture, bridges, machinery manufacturing and many other fields, the rust problem on the surface of steel structure parts is directly related to the safety, stability and service life of the structure. Long-term exposure to complex and changeable environments, the surface of steel structure parts is prone to rust accumulation, which not only affects its aesthetics, but more importantly, will reduce the bearing capacity of the structure and increase potential safety hazards.

[0003] Traditional rust removal methods for steel structure parts mostly use manual grinding or sandblasting. These methods have disadvantages such as low efficiency, high labor intensity, and uneven rust removal, and are difficult to meet the production requirements of large-scale and high-efficiency. In addition, the anti-rust maintenance after rust removal of steel structure parts is equally crucial. Traditional anti-rust treatment often requires manual spraying with a spray gun. This process is not only time-consuming and laborious, but also the spraying quality is easily affected by the skill level of the operator, making it difficult to ensure the coating uniformity and protection effect. At the same time, manual spraying also has potential safety hazards, such as the harm of paint volatilization to human health and the fire risk during the spraying process.

[0033] When the present invention is in use, the steel structure member 6 to be derusted is placed between the two clamping seats 5, and the steel structure member 6 is placed inside the arc-shaped rotating block 20. Then, the two hydraulic cylinders 3 are started to extend, driving the two clamping seats 5 to move closer to each other. The two ends of the steel structure member 6 are clamped and fixed by the two clamping seats 5. At this time, the grinding derusting piece 28 contacts the surface of the steel structure member 6. The elastic force of the spring 30 acts on the grinding derusting piece 28, making the grinding derusting piece 28 fit the surface of the steel structure member 6.

[0034] Then, the second motor 22 is started to drive the rotating shaft 26 to rotate. The rotating shaft 26 drives the transmission wheel 24 to rotate. By the transmission action of the transmission wheel 24 and the transmission belt 25, the two rotating shafts 26 can rotate synchronously. Furthermore, the two friction driving wheels 23 can be driven to rotate synchronously. The limiting strip 19 can be driven to rotate by the friction driving wheel 23, and the arc-shaped rotating block 20 can be driven to rotate by the limiting strip 19. Furthermore, the grinding derusting piece 28 can be driven to rotate circumferentially around the steel structure member 6. The surface of the steel structure member 6 is ground and derusted by the grinding derusting piece 28.

[0035] Then, the first motor 15 is started to drive the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the moving seat 11 and the moving seat 11 is limited and guided by the hollow guide rod 8, the moving seat 11 can be driven to move leftward, driving the grinding derusting piece 28 to move and grind the rust on the surface of the steel structure member 6. At the same time, when the moving seat 11 moves leftward, due to the magnetic attraction between the magnetic sliding plug 32 and the sliding sleeve 33, the magnetic sliding plug 32 can be driven to move leftward inside the hollow guide rod 8. Furthermore, the rust preventive oil can be continuously sucked into the hollow guide rod 8 through the second connecting pipe 17.

[0036] When the moving seat 11 moves to the left extreme position, the surface derusting operation of the steel structure member 6 can be completed. At this time, the second motor 22 is stopped, and then the first motor 15 is reversed to drive the moving seat 11 to move rightward to reset. At this time, when the moving seat 11 moves rightward, the magnetic sliding plug 32 can be driven to move rightward by the sliding sleeve 33. Then, the rust preventive oil inside the hollow guide rod 8 is extruded and pumped into the arc-shaped spray pipe 13 through the first connecting pipe 14. Then, the rust preventive oil is sprayed on the surface of the steel structure member 6 through the nozzle 31, realizing the rust prevention and maintenance operation on the surface of the steel structure member 6.
