Abstract
The utility model relates to a reverse balance flange, which is provided with a single reverse balance flange. The single reverse balance flange is provided with a flange shell section, an annular flange plate, a support plate and a flange inner reinforcing drum. The inner lateral face of the flange shell section is welded with both the outer lateral face of the annular flange plate and the outer lateral face of the support plate, and both the inner lateral face of the annular flange plate and the inner lateral face of the support plate are welded with the flange inner reinforcing drum. More than one bolt hole is arranged on the annular flange plate and the support plate, and a connection balance surface is arranged on the upper end face and the lower end face of the flange shell section and on the upper end face and the lower end face of the flange inner reinforcing drum respectively. The flange inner reinforcing drum is adopted to replace a rib plate so that workload of producing the rib plate is reduced. The reverse balance flange can use automatic submerged arc welding to perform assembly and welding, thereby greatly improving the efficiency of flange production and quality of the assembly and welding.
Description
Technical field
The utility model relates to a kind of reverse balance flange, connects reverse balance flange especially for the 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 as shown in Figure 1, has flange shell ring, annular flange plate, strengthens gusset, and outer side surface and the flange shell ring of strengthening gusset are welded to connect, and the flange shell ring is provided with reinforcement gusset bottom and is connected supporting plane.Because it is many to strengthen gusset longitudinally, generally there be more than 100, welding needs manual welding, do not realize automatic weldering, inefficiency, quality are not easy to be guaranteed, and because weld seam is many, welding all needs groove opening, and welding deformation is big, welding stress is big, and postwelding can't be correcting deformed, and gusset end face supporting surface needs postwelding processing in addition, because each gusset is discontinuous, processing gets up to produce interrupted cutting, and the damage cutter influences work efficiency.
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 weldering automatically of being convenient to realize is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of reverse balance flange, has reverse balance flange monomer, described reverse balance flange monomer has the flange shell ring, the annular flange plate, dunnage, strengthen tube in the flange, the outer side surface of the inner side surface of flange shell ring and annular flange plate, the outer side surface of dunnage all is welded to connect, the inner side surface of annular flange plate, the inner side surface of dunnage all is welded to connect with the interior tube of strengthening of flange, have more than one bolt hole on described annular flange plate and the dunnage, strengthen in described flange shell ring and the flange on the tube, the lower end surface is equipped with the connection equilibrium surface.
Further, parallel and have certain distance between described annular flange plate and the dunnage.
Further, the quantity of described reverse balance flange monomer is a pair of, and a pair of reverse balance flange monomer has identical tapering and joins end to end, and the annular flange plate of a pair of reverse balance flange monomer and dunnage connect by common bolt.
Further, the weld seam that the outer side surface of the inner side surface of described flange shell ring and annular flange plate, the outer side surface of dunnage are welded to connect is a circumferential weld, strengthening a weld seam that is welded to connect in the inner side surface of annular flange plate, the inner side surface of dunnage and the flange is circumferential weld, can use automatic submerged arc welding to carry out assembly welding.
The shell ring of superposed reverse balance flange monomer and last tower tube is welded to connect, and is positioned at the reverse balance flange monomer of bottom and the shell ring of following tower tube and is welded to connect.
The beneficial effects of the utility model are: the reinforcement tube has replaced gusset in the flange owing to adopt, thereby the assembly welding difficulty of this reverse balance flange is greatly reduced, and reduced to make the workload of gusset, the utility model is because all assembly welding processes all are circumferential weld, can use automatic submerged arc welding to carry out assembly welding, improve efficient and assembly welding quality that flange is made widely.
