[0002] At present, in the process of installing wind turbine towers in wind power construction, a new type of reverse flange connection between towers is gradually being promoted due to its high stability and accurate positioning. It must be difficult. The current installation method is to set up a jack at the rib plate inside the flange surface to slowly align the flange. This installation method makes the installation time of each section of the tower tube at least two hours. This patent intends to design a Lightweight and convenient structural alignment tool to simplify the installation process and speed up installation efficiency

The invention relates to a portable flange correction installation device. The portable flange correction installation device comprises a pair of special bolts, a pair of special tapered iron and a pair of bases; each special bolt is composed of a spherical bolt head, a rectangular middle portion and a cylindrical bolt body; the bases are in circular truncated cone shapes, and a semicircle sunken part capable of being matched with the bolt head of each special bolt is arranged on each base; bolt holes capable of containing the special bolts are formed in the special tapered iron, and the special bolts are inserted into the bolt holes; and the bases are arranged between the bolt heads of the special bolts and lower flanges of cylinder flange connectors to achieve the fixing effect. The special bolts are bolts obtained after heat treatment. The special tapered iron and the bases are made of Q345 steel. By means of the portable flange correction installation device, the tower cylinder installation time can be greatly shortened, and the installation time can be controlled to be about 1 hour.
Description
technical field [0001] The invention relates to the field of flange correction installation, in particular to a portable flange correction installation device. Background technique [0002] At present, in the process of installing wind turbine towers in wind power construction, a new type of reverse flange connection between towers is gradually being promoted due to its high stability and accurate positioning. It must be difficult. The current installation method is to set up a jack at the rib plate on the inner side of the flange to slowly align the flange. This installation method makes the installation time of each tower tube at least two hours. This patent intends to design a Lightweight and convenient structural alignment tool to simplify the installation process and speed up installation efficiency. Contents of the invention [0003] In order to achieve the above object, the present invention provides a portable flange correction installation device, including a pai...
