Special spraying device for wind-power tower

Abstract

The invention relates to a special spraying device for a wind-power tower, belonging to special spraying devices. The invention avoids the defects of nonuniform thickness, missing spraying, sagging, pinhole formation, wrinkle, serious paint waste, and the like of a tower spraying paint film, and is characterized in that according to pattern requests, a positioning fixed disk is arranged on a platform to be leveled and then is fixedly welded by the welding mode of manual butt joint, a central point is found out so as to line out positioning lines of a roller and a positioning fixed hole and todrill out the positioning fixed hole, the roller is coiled, longitudinal seams of the roller are welded by the mode of automatic welding, and circle checking is carried out until meeting the qualification; according to the pattern requests, the roller and a rib plate are positioned and are fixed by spot welding on the positioning fixed disk, and meanwhile, symmetrical manual fillet welds are welded on the positioning fixed disk so as to prevent welding deformation; and according to patterns, a positioning retainer ring is welded, and finally the integral production of the spraying device is accomplished. The invention used for spraying has the advantages of smooth surface of paint and no defects of sagging, pinhole formation, wrinkle, and the like, and greatly improves the spraying quality.

Description

1. Technical field: [0001] The invention relates to a special device for spraying a wind power tower, and belongs to a special device for spraying. 2. Background technology: [0002] As the key supporting equipment of wind turbines, the wind power tower has high manufacturing precision requirements. In addition to the shape and position tolerances such as coaxiality, flatness, parallelism, straightness, and misalignment, the tower’s anti-corrosion requirements are also quite high. strict. [0003] According to the actual situation of the wind turbine exposed to the corrosive environment, according to the requirements of ISO12944-2, the outer surface of the tower belongs to the corrosion category C 5 -M (excluding marine areas) and C 5 -I inner surface belongs to corrosion category C 4 According to the requirements of ISO12944-1, the anti-corrosion protection level of the tower is "long-term", the effective life is 15 years, and the depth of internal corrosion does not exc...
