Description
Technical Field
The utility model relates to a wind power tower construction field specifically is a tower section of thick bamboo flange non-contact surface protection frock.
Background
The tower of the wind power tower is generally formed by splicing a plurality of sections of tower barrels, each tower barrel is formed by welding a barrel body and two flange ring pairs, and adjacent tower barrels are connected at the flange through high-strength bolts and nuts. In the tower barrel, the flange is the most rusty part, and proper anti-corrosion measures must be taken for the flange of the tower barrel so as to ensure the service life of the wind power tower. At present, hot spray zinc treatment needs to be carried out on a non-contact surface (a plane which is in contact with high-strength bolts and nuts connected with adjacent towers) of a tower flange in the wind tower manufacturing industry, and the contact surface (the plane in direct contact with the flanges between the adjacent towers), an inner circular surface, and the corrosion prevention of the inner wall and the outer wall of a cylinder body can adopt a conventional spray painting method, so that a metal zinc protective layer formed by hot spray zinc can play double roles of corrosion prevention and grounding (the conduction between the adjacent towers is realized by the aid of the high-strength bolts and the nuts). In addition, in consideration of the high temperature generated by the thermal spraying of zinc, the corrosion prevention measures should be performed in the order of thermal spraying zinc first and then spraying paint.
Because a paint film has insulativity, the non-contact surface of a tower cylinder flange needs to be isolated and protected before paint spraying, the conventional method at present is to paste a masking tape to cover a metal zinc protective layer when the tower cylinder flange is in non-contact with the surface, but the pasting process is time-consuming and labor-consuming, and the masking tape also has the defects of incapability of being repeatedly used, easiness in damage, easiness in degumming and the like, so that a protection tool which is easy to mount to the non-contact surface of the tower cylinder flange and can be repeatedly used needs to be developed.
