Description
Technical Field
The invention relates to the field of manufacturing of wind power generation tower barrels, in particular to a fixing platform for welding flanges.
Background
The wind power tower barrel is a tower pole of wind power generation, and mainly plays a supporting role in a wind generating set and absorbs the vibration of the set.
The wind power generation tower barrel is a key supporting component of a wind power generator, and is a conical cylindrical structure formed by a plurality of sections of conical barrel bodies through connecting flanges, and each section of tower is formed by welding a rolled barrel body and the connecting flanges. A wind power generation tower cylinder is usually a tower cylinder structure, the bottom of the wind power generation tower cylinder is connected with a foundation, a generator and a wind wheel are installed at the top of the wind power generation tower cylinder, and a ladder stand for up-down traffic, a cable for transmitting electric energy and the like are arranged inside the tower cylinder.
In a wind power tower cylinder, flanges are very important connecting parts, most of the existing flanges are of annular integral structures, and can be produced in two ways, one is casting, but the casting way has low production efficiency; the other is welding, that is, a plurality of arc-shaped workpieces are welded end to form a circular flange, for example, chinese patent specification No. 2016104097861 discloses a welding type flange, the flange body of which is formed by welding a plurality of split bodies end to end. However, the welding type flange has high requirements on the welding process, and local deformation is easy to occur, so that the whole flange is not flat.
Disclosure of Invention
The invention aims to provide a fixing platform for welding flanges, which can prevent the flanges from deforming and improve the quality of welding seams.
In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a fixed platform for welded flange, the flange is formed by the welding of a plurality of arc work piece end to end, fixed platform includes platform panel and supporting leg, the platform panel is used for placing treats the welded arc work piece, it is provided with a plurality of hold-down mechanism still to the interval on the platform panel, hold-down mechanism can make the arc work piece closely paste the platform panel.
During the use, place a plurality of arc work pieces on the platform panel, enclose into the ring form, reuse hold-down mechanism compresses tightly each arc work piece respectively, makes the arc work piece closely paste the platform panel, then welds again, just so can prevent the deformation of flange, and can improve the welding seam quality, improves work efficiency.
Preferably, the fixed platform is formed by combining a plurality of platform panels to form a circular ring. By adopting the mode, the manufacturing is convenient, and the cost can be saved.
In one embodiment, the pressing mechanism comprises two supports welded on the platform panel and a pressing plate, and two ends of the pressing plate are respectively connected with the supports through bolts. The structure is simple and reliable, and the operation is convenient.
In one embodiment, the number of the arc-shaped workpieces and the number of the platform panels are six.
In one embodiment, the support legs are made of H-section steel.
