Problems solved by technology

[0002] When the flange is installed on the traditional large-scale mechanical tower, the flange is placed on the roller frame for horizontal welding installation. As the diameter of the tower becomes larger and larger, the permanent deformation caused by the self-weight during the construction process becomes more and more serious. At the same time, the welding deformation and inclination value of the large-diameter tower flange are becoming more and more prominent. It is difficult to meet the requirements of the owner for the flatness, ellipticity and inclination value of the flange after welding. Therefore, how to solve the above problems is to ensure that the tower The key to the construction quality of the tube. At present, in order to solve this problem, the installation method of vertically closing the tower tube and the flange is proposed. When the vertical direction of the tower tube and the flange is closed, a tire frame device for the flange is required.
[0003] The existing tire frame device for vertically closing the large-scale mechanical tower and the flange is composed of a plurality of base groups in a circular structure. The flange is placed above the base group. Since the diameters of the flange and the tower are different, each When placing the flange for the first time, it is necessary to change the position of the base group to meet the needs of flanges and towers with different diameters, and when changing the position of the tire frame device, it is impossible to ensure that multiple tire frame devices form a circular structure, which is time-consuming and labor-intensive , the work efficiency is low, due to the large volume of the large mechanical tower and the flange, there is a certain inconvenience during welding or transportation after welding
