Description
Technical field
The utility model relates to a kind of wind turbine tower flange group to frock, is specifically related to organize shaped device between a kind of wind turbine tower flange and tower cylinder.
Background technology
According to conventional art, two large technological deficiencies are arranged after wind power flange and the moulding of tower cylinder barrel soldering; Flange turn up and the Flange Plane unevenness and ovality overproof.
In conventional art, flange and tower cylinder group are that cylindrical shell is lain in a horizontal plane in group on positioner to method, with crane, flange is sling, by the gap between the right method adjustment flange neck of artificial group and body end surface and the circumference both dock.Have following problem: 1, under Action of Gravity Field, ovality unavoidably appears in cylindrical shell in the horizontal direction, and because the flange rigidity is stronger, the flange ovality shows not obviously.This moment, the operator utilized the right method of powerful group that two workpiece are connected and welded together, and two workpiece consist of a workpiece, and the ovality of cylindrical shell is delivered on flange, and this is the main cause that ovality appears in flange.2, this kind group makes gap between flange neck and body end surface be difficult to accomplish tight coincideing to mode, and the gap that occurs between both is that flange face produces wave transformation so that affects the major reason of planeness of flange under the unequal impact of welding contracted quantity.Mainly that distortion by welding stress produces causes because flange turns up, this utility model put forth effort to solve wind power flange and tower cylinder welding fabrication rear flange plane ovality overproof with the overproof problem of unevenness.
The utility model content
The utility model is in order to solve the problem that the Flange Plane unevenness is overproof and ovality is overproof that produces after wind power flange and the moulding of tower cylinder barrel soldering, and then provides a kind of wind power tower flange group to frock.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
Frock described in the utility model comprises platform, flange, tower cylinder and a plurality of ground way assembly, and each ground way assembly comprises active block stop, support, pressing plate, voussoir and two tight fixed bolts; A plurality of ground way assemblies evenly arrange on described platform by circumferencial direction, and each pressing plate center line along its length is coplanar and meet at a bit, and the inner of each pressing plate can contact with the outer circumference face of flange; Active block stop on each ground way assembly, support and pressing plate three weld together, and active block stop is being provided with support on pressing plate and both; Each active block stop can contact with the outer circumference face of flange; The tower cylinder be positioned at flange directly over, be provided with a voussoir between tower cylinder and each active block stop, each pressing plate is provided with two tight fixed bolts.
The technical scheme that the utility model further limits is: the quantity of described a plurality of ground way assemblies is 16.
The present invention compared with prior art has following effect: 1, under Action of Gravity Field, flange neck and body end surface reach seamless connectivity, and this is that conventional art is difficult to accomplish.Known from institute, if flange neck and body end surface gap are inhomogeneous, under the welding stress effect, the flange face amount of contraction does not wait, and producing thus the Flange Plane wave transformation will directly cause planeness of flange overproof.2, flange and cylindrical shell are vertically installed by center line, make cylindrical shell reduce the generation of ovality under Action of Gravity Field, but small out-of-roundness are difficult to avoid.This device is adjusted the out-of-roundness of cylindrical shell by the active block stop of tightening at the circumferencial direction of flange by moving up and down of each drift, making relatively, the flange in garden is not subjected to external force, avoid the brute force assembling of traditional handicraft, thereby reached the overproof problem of control flange ovality.What should be noted that at this is should control as strict as possible the flatness of body end surface before flange and Cylinder assembly, from plate cutting to roll can make body end surface flatness be affected, each operation should take necessary measure to be guaranteed.As overproofly in flatness must carry out reconditioning, just can be grouping after the quality inspection personnel assay approval.The flatness guarantee that has guaranteed body end surface is gapless group pair both.
