Abstract
The utility model relates to an L-shaped flange disc connecting way of a tower cylinder connecting structure of a wind generating set and belongs to the technical field of wind generating set. L-shaped flange discs (3) are adopted by the tower cylinder connecting structure of the wind generating set; the corners of the L-shaped flange discs (3) are provided with chamfers (5); the L-shaped flange discs (3) are welded and connected with the end part of each section of the tower cylinder (4); the L-shaped flange discs (3) of the tower cylinder at the two ends are connected together by a bolt. The L-shaped flange discs (3) are welded at the end parts of the two ends of the tower cylinder; and connection between sections is realized by the bolt. The connecting way can be adopted to effectively reduce the thermal stress of the tower cylinder generated due to welding; meanwhile, as the design of the chamfer is adopted which avoids stress concentration generated at the included angle of the flange disc; and the L-shaped flange discs enhance the enablement of a welding technology, which improves the safety of the tower cylinder of the wind generating set.
Description
Technical field
The utility model relates to a kind of wind power generating set, relates in particular to a kind of linkage structure of wind power generating set tower tube L type flange plate.
Background technique
Wind power generating set tower tube generally all surpasses 45m, since all limit decision of transportation aspect tower tube merogenesis connect, Placement is to link together by the flange plate that bolt will be welded on the every joint of tower tube end between the joint of wind power generating set tower tube and the joint now, existing tower tube mounting flange adopts the flat pattern flange plate, as shown in Figure 1, the flange plate of this form is need be at groove opening on flange plate 1 and the tower tube cylindrical shell 2 on the welding procedure, and because flange plate is when welding with tower body, there is the welding residual thermal stress, thereby can cause stress to concentrate at connection part causes the tower tube to lose efficacy, even rupture, produce very serious consequence.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of wind power generating set tower tube linkage structure, the Security that purpose is that welding residual thermal stress that its welding process is produced is reduced to is minimum, the welding procedure exploitativeness strong, can improve wind power generating set tower tube.
For achieving the above object, the utility model is achieved through the following technical solutions:
Wind power generating set tower tube linkage structure adopts L type flange plate, and the corner of L type flange plate is provided with chamfering, and the end of L type flange plate and each section tower tube is welded to connect, and the L type flange plate of two head tower tubes links together by bolt.
The radius of described chamfering is 5-20mm.
The utility model has the advantages of: when adopting conventional flat pattern flange to connect, the weld seam form of flange plate and cylindrical shell is overlap joint, bevel for welding is " V " type, the exploitativeness of welding procedure is relatively poor, and owing to the angle of weld seam at flange plate and cylindrical shell, form stress easily and concentrate, in tower tube working procedure, be subjected to rupturing extremely easily under the effect of alternate load and shearing stress.When the utility model adopts L type flange to connect, the weld seam form of flange plate and cylindrical shell is for docking, bevel for welding is two " V " types, welding procedure can be real-time, simultaneously since weld seam on cylindrical shell, avoided flange plate when welding with tower body, the stress that the welding residual thermal stress that produces causes at connection part is concentrated and is caused the tower tube to lose efficacy, adopt the utility model design to have the L type flange plate of chamfering can avoid producing the phenomenon that stress is concentrated, avoided the tower tube owing on the flange angle, existing stress to concentrate the inefficacy that causes in the corner; Planeness and parallelism for flange made regulation in design simultaneously, becomes easily with regard to the installation that makes the tower tube like this, reduced manpower and materials, improved the Security of wind power generating set tower tube.
Description of drawings
Fig. 1 is conventional flat pattern flange plate linkage structure schematic representation.
Fig. 2 is the utility model L type flange plate linkage structure schematic representation.
Among the figure, 1, flange plate, 2, tower tube cylindrical shell, 3, L type flange plate, 4, the tower tube, 5, chamfering.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
Wind power generating set tower tube linkage structure, its concrete structure is as follows: the corner of L type flange plate 3 is provided with chamfering 5, and L type flange plate 3 is welded to connect with the end of each section tower tube 4, and when the tower tube connected, the L type flange plate of two head tower tubes linked together by bolt.The radius of above-mentioned chamfering 5 is 5-20mm, and the best is 10mm.
Claims (2)
1. wind power generating set tower tube linkage structure, it is characterized in that adopting L type flange plate (3), the corner of L type flange plate (3) is provided with chamfering (5), and L type flange plate (3) is welded to connect with the end of each section tower tube (4), and the L type flange plate (3) of two head tower tubes links together by bolt.
2. wind power generating set tower tube linkage structure according to claim 1, the radius that it is characterized in that described chamfering (5) is 5-20mm.
