Abstract
The utility model relates to a counter balanced flange used in large-scale wind power generation equipment in wind fields, and belongs to pipe connection pieces. The counter balanced flange comprises a cylindrical segment, flange plates, and a plurality of stiffening plates, wherein a plurality of bolt holes are formed on each flange plate; all the stiffening plates are arranged in front of the flange plates; the front end surface of each stiffening plate is provided with a balanced contact surface; and the cylindrical segment is tapered. The utility model has the advantages that the cylindrical segment has the same taper with the cylindrical segment of a mast; the load-carrying capability of the flange is also improved; the assembly and the installation are easy; the difficulty in installation is reduced. The utility model also ensures that the transition of the connection of the mast is smooth, the integral appearance of the mast is attractive, and the quality is stable; meanwhile, the maintenance frequency of the mast of a wind powered generator is reduced.
Description
Technical field
The utility model relates to a kind of reverse balance flange, is used for large-scale wind field wind power plant, belongs to pipe joint.
Background technique
At present, the Connecting format of domestic all wind power generating set tower tube is traditional thick swaged forging part flange and connects, blower fan tower barrel generally is divided into three to four joints up and down, the taper shell ring that is welded by the roll of steel plate circle, because the position that is connected with the tower tube on the thick swaged forging part flange is the straight section shell ring, this has brought very big difficulty to installation just for group, and group to after profile also attractive in appearance inadequately.Utility model patent as the claimant, the patent No. 200720002665.1 adpting flanges, it comprises: flanged plate, a plurality of stiffened plate, shell ring, on flanged plate, be provided with a plurality of bolts hole, each stiffened plate is positioned at the front side of flanged plate, and the front-end face of stiffened plate is provided with the balance surface of contact, and this adpting flange welds together by straight section shell ring and tower tube.So group is big to, the difficulty of installing, tower tube group is more obvious to the protruding phenomenon at position, and this has just influenced the image appearance of tower tube integral body greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of can reduce the wind-power tower installation cost, group to, install easily, tower tube overall appearance is attractive in appearance, the reverse balance flange of stay-in-grade taper.
The technical scheme in the invention for solving the technical problem is:
The utility model comprises: shell ring, flanged plate, a plurality of stiffened plate, on flanged plate, be provided with a plurality of bolts hole, each stiffened plate is positioned at the front side of flanged plate, and the front-end face of stiffened plate is provided with the balance surface of contact, shell ring be shaped as taper.
Described shell ring and tower tube shell ring are same tapering.
The utility model shell ring and tower tube shell ring are same tapering, and flange stressed also played the improvement effect, group to, install easily, reduced installation difficulty, what guaranteed that the tower tube connects seamlessly transits, and makes tower tube overall appearance attractive in appearance, steady quality.Reduced simultaneously blower fan tower barrel freedom from repairs number of times.
