Abstract
The utility model discloses a counter flange for preventing the welding deformation of a wind tower flange. The counter flange comprises an upper body and a lower body which are matched with the flange, reinforcing bars are welded between the upper body and the lower body, body bolt holes are also arranged at positions on the circumferences of the upper body and the lower body, which correspond to bolt holes of the flange, and the flange is fixed on the upper body by bolts. Because the counter flange is tightly connected with the flange by the bolts before welding, the amount of deformation of the flange is reduced, and is controlled within a designed range; the counter flange can be dismounted and repetitively used, consequently, the fabrication cost is low, the workload is decreased, the requirement on workers is low, so that the counter flange can be operated by ordinary skilled workers, a great deal of manpower and a large quantity of material and financial resources are saved, considerable economic benefit is brought, and the efficiency and technique of production are increased.
Description
Technical field
The utility model relates to a kind of wind tower flange that prevents and produce the device of distortion in welding process, is a kind of anti-flange that prevents the wind tower flange welding deformation specifically, guarantees flange postwelding flatness.
Background technology
The wind-power electricity generation pylon is because the restriction of length generally will be divided into several sections processing and fabricatings.And segmentation place is to connect with flange, and whether the size of planeness of flange is directly connected to flange and can closely links together.The flatness that general design all requires control flange within 1.5mm, top flange especially, because of being connected with the cabin, its flatness requirement is higher, be controlled within the 0.5mm.
The control of tower drum flange flatness generally was the control solder technology in the past, and postwelding adopts the method for plate fairing by hot working to carry out.This method is very strict to the specification requirement of welding, needs very high solder technology experience, and personnel are required height, and welding needs control welding times, order, consuming time and inefficiency.Simultaneously, after welding is finished, also need plate fairing by hot working, the firer is required strict more, the control of Flange Plane needs a large amount of experience accumulation of personnel just can implement fully, because the high-tech talent's restriction, and required high-precision requirement in the time of can't guaranteeing to produce in enormous quantities.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of anti-flange that prevents the wind tower flange welding deformation is provided, and the deflection that it can effectively reduce flange satisfies high-precision requirement, overcomes the restriction that highly qualified professional's deficiency is brought.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of anti-flange that prevents the wind tower flange welding deformation, it comprises upper body and the following body adaptive with flange, be welded with reinforcement between upper body and the following body, the position corresponding with flange screw also is provided with the body bolt hole on the circumference of upper body and following body, by bolt flange is fixed on the upper body.
Wherein, described upper body, following body steel plate, described reinforcement is a steel plate.
Beneficial effect: anti-flange of the present utility model closely is connected with flange by bolt before weldering, reduces the deflection of flange, and the control deflection is within scope of design; Anti-flange of the present utility model is detachable, can use repeatedly, thus low cost of manufacture, under the big more situation of volume production, its use cost is low more; The distortion in control flange when welding reduces workload effectively, to personnel require lowly, be applicable to general technology workman operation, saved great amount of manpower and material resources and financial resources, brought considerable economic, production efficiency and skill upgrading.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, 2, a kind of anti-flange that prevents the wind tower flange welding deformation of the present utility model, it comprises upper body 1 and the following body 1 adaptive with flange, upper body 1, following body 2 are steel plate; Upper body 1, following body 2 and flange outer diameter size basically identical.Be welded with reinforcement 3 between upper body 1 and the following body 2, reinforcement 3 is steel plate, can prevent effectively that anti-flange is subjected to external force and causes self-deformation, thereby lose its due function.
The position corresponding with flange screw also is provided with body bolt hole 4 on the circumference of upper body 1 and following body 2, by bolt 5 flange is fixed on the upper body 1.The quantity of the body bolt hole 4 also number of bolt holes in flange amount with corresponding is consistent, can guarantee that like this bolt 5 is in place accurately.
Shown in Figure 2, B is a flange among the figure, and the anti-flange of wind tower flange welding deformation that prevents of the present utility model should use before flange and cylindrical shell welding, in use, by bolt 5 flange and anti-flange is coupled together; Because spanner can't put in anti-flange apparatus inside, the body bolt hole 4 of anti-flange all is threaded, and directly bolt 5 is tightened to get final product.Must guarantee simultaneously all bolts hole all screw on bolt 5, the flatness of the assurance flange of ability out to out like this.
In welding process, owing to there is bolt 5 flange to be fitted in closely on the upper body 1 of anti-flange, therefore originally because the distortion that welding causes, can effectively control, its deviations from planarity substantially all is controlled within the 1mm scope, the 1.5mm deviation that adheres to specification fully, and flatness is controlled within the higher scope.And the control accuracy of top flange, because of the top flange diameter less than normal, thereby the more anti-deformation requirement of I when satisfying the higher top flange welding of precision substantially of actual deviation.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
