Abstract
The utility model discloses a modified tower section of thick bamboo flange structure, it includes L type flange, L type flange includes first section and second section, first section and the perpendicular body coupling of second section, and first section goes up to open there is the bolt hole, and inboard the opening of second section has the stress groove, and the increase of second section tip has the nipple joint. Increase the stress groove on former L type flange basis, reduce flange and barrel welding stress through increasing the nipple joint, reduce the influence to flange welding deformation, and nipple joint and flange welding stress obtain release through the stress groove, the plane degree of final flange is with turn up or control is warp at effectual within range to the fall -in.
Description
Technical field
The utility model relates to a kind of tower drum flange, particularly relates to a kind of tower drum flange structure of improvement.
Background technique
Design and produce at tower cylinder, widely, but there are two drawbacks in this flange in L-type tower drum flange (as Fig. 1) application, after weld with cylindrical shell 1 ', and the planeness of flange 2 ' and to turn up or introversion is out of shape and is can not get effectively controlling.If these two drawbacks continue circulation to subsequent installation process or in using, immeasurable serious consequence will be caused, by the planeness of final flange and turn up or introversion Deformation control in effective scope.
Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of tower drum flange structure of improvement.
For solving the problems of the technologies described above, the tower drum flange structure of a kind of improvement of the present utility model, it comprises L-type flange, described L-type flange comprises first paragraph and second segment, described first paragraph and second segment vertically one are connected, described first paragraph has bolt hole, has stress groove inside described second segment, described second segment end increases pipe nipple.
The length of described pipe nipple is 900mm.
The beneficial effects of the utility model: increase stress groove on former L-type flange basis, flange and barrel soldering stress is reduced by increasing pipe nipple, reduce the impact on flange welding distortion, and pipe nipple and flange welding stress are discharged by stress groove, the planeness of final flange and turn up or introversion Deformation control in effective scope.
Accompanying drawing explanation
Fig. 1 is the structural representation of tower joint in prior art.
Fig. 2 is structural representation of the present utility model.
Wherein: 1, L-type flange, 11, first paragraph, 12, second segment, 2, bolt hole, 3, stress groove, 4, pipe nipple.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As shown in Figure 2, the tower drum flange structure of a kind of improvement of the present utility model, it comprises L-type flange 1, L-type flange 1 comprises first paragraph 11 and second segment 12, first paragraph 11 is connected with the vertical one of second segment 12, first paragraph 11 has bolt hole 2, have stress groove 3 inside second segment 12, second segment 12 end increases pipe nipple 4.
This kind of flange has two-part to form, and first portion increases stress groove 3, second portion on former L-type flange basis, increases the pipe nipple 4 of about 900mm.Flange and barrel soldering stress is reduced by increasing pipe nipple 4, reduce the impact on flange welding distortion, and the welding stress of pipe nipple and flange first portion is discharged by the stress groove offered, the welding of this part is also the method having used for reference reserved welding anti-distortion amount simultaneously, distortion and the correction of flange complete in the welding process of this part, the pipe nipple blank of second portion suitably thickeies, after object is to roll welding forming, can carry out to internal-and external diameter the circularity that secondary operations reaches satisfied, and don't affect actual desired thickness.
The usual wind-force in place of wind-power electricity generation is comparatively large, and working environment is more complicated.And pylon bears is fatigue load, poor circularity can attach larger welding stress, can produce larger harmful effect under the effect of the fatigue load of going round and beginning again.
By welding rear measurement, this novel flange gets a desired effect, and this pattern is workable, and Be very effective substantially increases productivity, obtains significant economic benefit, should be widely promoted.
Claims (2)
1. the tower drum flange structure improved, it is characterized in that: it comprises L-type flange, described L-type flange comprises first paragraph and second segment, described first paragraph and second segment vertically one are connected, described first paragraph has bolt hole, have stress groove inside described second segment, described second segment end increases pipe nipple.
2. the tower drum flange structure of a kind of improvement according to claim 1, is characterized in that: the length of described pipe nipple is 900mm.
