Description

Automatic paint repair device for inside of large-caliber steel pipe Technical Field The utility model relates to the technical field of steel pipe paint repair, in particular to an automatic paint repair device for the interior of a large-caliber steel pipe. Background The steel pipe is used as an important steel structural member with extremely wide application and plays a key role in various engineering fields. After the steel pipe is welded, the original protective layer is often damaged in the specific area in the steel pipe due to the welding process, and paint repair operation is needed, so that the corrosion resistance of the steel pipe is enhanced, and the service life of the steel pipe is obviously prolonged. Taking a large-caliber steel pipe as an example, after the welding process is finished, the butt joint area in the pipe is a paint repair area, and according to engineering standards, multiple paint repair operations are usually required to be carried out, so that the protection requirement can be fully met. When the manual paint repair method is commonly adopted in the industry, but the labor intensity is high due to manual operation, workers are forced to be placed in a narrow and poorly ventilated severe environment in the steel pipe for a long time for continuous operation, and serious threat is caused to the physical health of the workers. On the other hand, the manual paint repair efficiency is extremely low, and the large number of steel pipes in large-scale engineering are faced, so that paint repair tasks are difficult to complete on time, and the engineering progress is severely restricted. In addition, the quality of the paint repairing is excessively dependent on the technical level and the real-time working state of an individual worker, so that the conditions of uneven thickness, local leakage repair and the like of the paint repairing easily occur in the paint repairing process, the paint repairing effect is finally not expected, and the protective performance and long-term stable use of the steel pipe cannot be practically ensured.
