Description

Technical Field

[0001] The utility model belongs to the technical field of anti-corrosion treatment, and in particular relates to an anti-corrosion treatment device for the surface of a steel structure in a civil engineering project. Background Art

[0002] Steel structure is an important form of building structure. It has the characteristics of high strength, high rigidity and light weight. It is widely used in various buildings and projects. The basic types of steel structure include frame structure, grid structure and thin shell structure. Among them, frame structure is one of the most common forms of building structure. Its basic components are a frame composed of steel columns and steel beams. The surface of the steel column needs to be treated with anti-corrosion before use. One of the most common anti-corrosion treatment methods is spraying anti-corrosion paint. The traditional method is manual spraying, but this method is inefficient, and the surface of the steel column needs to be polished before spraying the anti-corrosion paint to improve the spraying effect of the anti-corrosion paint. After searching, it was found that the application number "202321753695.1" discloses "a steel structure profile rust removal and anti-corrosion painting device", which records "including a workbench, a lower limit groove is opened at the lower part of the interior of the workbench, and the lower limit groove is rotatably connected to the lower screw, and the right side of the workbench is fixedly connected to a first motor, and the output end of the first motor is fixedly connected to the lower screw The lower limit block is movably inserted in the lower limit groove, and the lower limit block is threadedly connected to the lower screw rod. The workbench is movably sleeved with a movable frame, and the movable frame is fixedly connected to the lower limit block. When the above-mentioned painting device is in use, the lower screw rod is driven to rotate by the first motor, so that the lower screw rod drives the lower limit block and the movable frame to move the position. At this time, the paint spray nozzle and the laser rust removal head can be moved left and right. At this time, the laser rust removal head can remove rust on the steel structure profile, and the paint spray nozzle can spray paint on the steel structure profile. However, the above-mentioned device still has certain shortcomings when used: although the paint spray nozzle and the rust removal head can move left and right, due to the inconvenience of adjusting the installation position, the paint spraying and rust removal can only be carried out within the radiation range of the paint spray nozzle and the rust removal head, resulting in poor spraying effect at the corners of the steel structure, which in turn leads to poor anti-corrosion treatment efficiency of the steel structure. At the same time, when spraying paint, part of the anti-corrosion paint will splash outward, affecting the health of the staff. Based on this, we propose a device that can more efficiently perform anti-corrosion treatment on steel structures. Utility Model Content
