Targeting at the defects of manual operation during the overhaul of the external anti-corrosion coating on pipeline, an automation machine for winding the anti-corrosion coil was developed. Not only the structure and performance characteristics of the equipment were introduced, but also kinematic characteristics of the traveling mechanism were analyzed. Considering both the construction site environment and the test results, this scheme was optimized for improvement. After the completion of the prototype production, tests were carried out in a laboratory environment. The test indicators met the design requirements. The machine structure was reasonable and easy to operate. The test results demonstrated that the equipment greatly improved the efficiency and quality of the overhaul of the external anti-corrosion coating for the pipeline and reduced the labor intensity, which is of great significance for boosting the automation degree of pipeline repair equipment.
