Abstract
The utility model relates to a reverse balance flange of a tower drum, which is provided with single flange bodies; each single flange body is provided with a flange cylinder joint, an annular flange plate and a rib plate; more than one bolt holes are formed on the annular flange plate; a bearing ring is arranged at the bottom of the rib plate; the upper end and the lower end of the rib plate are respectively welded on the annular flange plate and the bearing ring; the outer side surface of the rib plate is welded with the inner side surface of the flange cylinder joint; and the flange cylinder joint and the bearing ring are both provided with connection bearing surfaces. Since the bearing ring is additionally welded on the lower end surface of the rib plate, the contact area of the bearing surface of the reverse balance flange of the tower drum is greatly increased, and the interrupted cutting during the turning process in following processes is avoided, which reduces the manufacturing difficulty of the flange, improves the manufacturing efficiency of the flange, and obtains better forced conditions in using so as to reduce the risk of the fan collapse due to flange failure.
Description
Technical field
The utility model relates to the reverse balance flange of a kind of tower tube, especially for the reverse balance flange of tower tube connection tower tube of MW class wind turbine group.
Background technique
Large-scale wind driven generator tower tube is mainly the taper tubular structure at present, is coupled together with bolt by flange by three to four sections shell rings up and down, and every section shell ring is welded to form the termination welded flange with the awl tube that steel plate rolls by plurality of sections.Form of flanges is mainly the whole ring rolling flange of the L shaped shape in cross section and the reverse balance flange that is welded.Whole ring rolling flange, because the cost height, manufacturing efficiency is low, and is uneconomical, soldered gradually flange replaces.The reverse balance flange of welding shown in Fig. 1-2, has flange shell ring, annular flange plate, gusset, and the upper end of gusset is welded on the annular flange plate, and the inner side surface of the outer side surface of gusset and flange shell ring is welded to connect, and the flange shell ring is provided with gusset and is connected supporting plane.Because the connection supporting plane of gusset end face needs postwelding processing, because each gusset is discontinuous, adds and can produce interrupted cutting man-hour, the damage cutter influences work efficiency.In addition, gusset is too small as the supporting plane area of contact of flange, and is difficult to guarantee that the position of a pair of gusset can not misplace up and down in the assembly welding process.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reverse balance flange of tower tube of being convenient to process and increasing flange supporting plane area of contact is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the reverse balance flange of a kind of tower tube, has the flange monomer, described flange monomer has flange shell ring, annular flange plate, gusset, offer more than one bolt hole on the described annular flange plate, described gusset bottom also is provided with load-carrying ring, the upper/lower terminal of described gusset is welded in respectively on annular flange plate and the load-carrying ring, the inner side surface of the outer side surface of described gusset and flange shell ring is welded to connect, and described flange shell ring is provided with load-carrying ring and is connected supporting plane.
Further, the quantity of described flange monomer is a pair of, the gusset of a pair of flange monomer has identical tapering, and the flange shell ring of a pair of flange monomer docks mutually with the supporting plane that is connected of load-carrying ring, and the annular flange plate of a pair of flange monomer connects by common bolt.
Further, described gusset has tapering part and vertical component, and the interior vertical surface of described gusset vertical component is welded with strengthens tube in the flange, strengthen tube bottom in the described flange and be provided with supporting plane.
The beneficial effects of the utility model are: welded load-carrying ring owing to increasing in the lower end surface of gusset, thereby the supporting plane area of contact of the reverse balance flange of this tower tube is greatly increased, and avoided interrupted cutting in the back operation turning process, reduced the flange manufacture difficulty, can improve the efficient that flange is made, and in use obtain better force-bearing situation, reduce the risk that lost efficacy and cause blower fan to collapse owing to flange.
