Background

With the popularization and application of the offshore wind power generation technology, the research and development investment of offshore wind towers is increased by various large wind turbine host manufacturers, and the occupation ratio of the offshore wind towers is increased year by year. In addition, competition in the wind power industry is intensified, and various manufacturers must consider how to realize the structural strength requirement of the wind tower at lower cost while researching and developing new machine types, and increasing the diameter of the tower barrel and reducing the thickness of the tower barrel plate are the most economical and rapid mode for realizing the purpose. Thus, large diameter thin plate wind towers are the mainstream development of offshore wind towers.

The manufacturing difficulty of the large-diameter thin plate offshore wind tower is greater than that of a conventional onshore wind tower, the large-diameter thin plate offshore wind tower is extremely easy to generate concave deformation in the manufacturing process, great difficulty is brought to assembly and welding, a new process needs to be applied to solve the problem, the existing manufacturing process is the same as the manufacturing process flow of the conventional onshore wind tower, tower sections are directly assembled on a roller frame, and due to the fact that the roundness of the tower sections is poor, the assembly consumes long time and is high in difficulty. After assembly, submerged arc welding is carried out by using a cross-arm frame vehicle, a tower section needs to rotate on a roller frame in the welding process, the roundness of the tower section is further deformed and severely shakes during rotation, welding forming is poor, the yield is low, and product quality is seriously affected. Therefore, aiming at the situation, the tool which is simple and convenient to operate, obvious in effect and capable of controlling the deformation of the tower barrel is designed.

In order to achieve the purpose, the invention provides the technical scheme that:

the utility model provides a frock for controlling circularity of major diameter wind tower sheet metal tower festival, includes the holding ring, and the holding ring openly is fixed with rather than endocentric beaded finish, and multiunit T shape hole has been seted up to the circumference equipartition on the holding ring of beaded finish inboard, all is provided with tight top mounted putting on the holding ring outside T shape hole and T shape hole, tight top mounted putting and holding ring fixed connection on the holding ring outside T shape hole, and the downthehole tight top mounted that tightly of T shape slides and sets up inside it, tight top mounted includes the roof, is fixed with the nut on the roof, sets up the hole that corresponds with the nut on the roof, fixes and the gusset on the roof, and top mounted's roof and gusset and locating plate fixed connection on.

Specifically, a top plate and a rib plate of the top tightening device on the positioning ring outside the T-shaped hole are perpendicular to the positioning plate, and an intersection point is formed between the axis of the nut and the axis of the positioning ring.

Specifically, the positioning ring is formed by welding a plurality of sector plates.

Specifically, the top tightening device on the positioning ring on the outer side of the T-shaped hole is positioned on the back of the positioning ring.
