Abstract
The utility model discloses a kind of high-power major diameter tower cylinder top section upper flange structure, it is characterized in that: the bottom welding of upper flange has a transition piece, the bottom wall thickness of this transition piece and tower cylinder top section wall thickness uniform thickness.The distortion that the utility model utilizes this flange arrangement can make up flange to occur in welding process, make main frame uniform force in running, the impact of the vibrations in fan operation on main frame is reduced to a minimum, and extends the working life of main frame.
Description
Technical field
The utility model relates to a kind of flange arrangement, specifically, relates to a kind of high-power major diameter tower cylinder top section upper flange structure, belongs to offshore high-power wind driven generator power field.
Background technique
At wind power industry, docked by flange between each section of tower cylindrical shell, and the section of top upper flange is connected with main frame, upper flange stressed more complicated and higher to planarity requirements.Whole tower cylinder cylindrical shell is linked as entirety with between flange by welding, and in order to ensure that the smooth running of main frame can save manufacture cost again, the principal element affecting flange docking order of contact is flange and tower cylinder welding process, namely requires that flange does not allow to turn up after welding.But because the barrel diameter of large-power tower cylinder is comparatively large, welding time flange be more easily out of shape, have a strong impact on flange docks operation quality with main frame.Therefore, a kind of new technological scheme is needed to solve above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is to provide a kind of high-power major diameter tower cylinder top section upper flange structure, this flange arrangement can make up the distortion that flange occurs in welding process, make upper flange and main frame uniform force in docking operation, main frame shakes and is compensated in running, improves the working life of main frame.
The technical solution adopted in the utility model is:
A kind of high-power major diameter tower cylinder top section upper flange structure, the bottom welding of its upper flange has a transition piece, the bottom wall thickness of this transition piece and tower cylinder top section wall thickness uniform thickness.
Further, the bottom inside of described upper flange is provided with transition arc.
The utility model has the advantages that: the distortion utilizing this flange arrangement can make up flange to occur in welding process, make main frame uniform force in running, the impact of vibrations in fan operation on main frame is reduced to a minimum, and extends the working life of main frame.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Wherein: 1, upper flange, 2, transition piece, 3, transition arc.
Embodiment
As shown in Figure 1, a kind of high-power major diameter tower cylinder top section upper flange structure, the bottom welding of its upper flange 1 has a transition piece 2, the bottom wall thickness of this transition piece 2 and tower cylinder top section wall thickness uniform thickness.In order to reduce flexural stress in welding stress and tower cylinder running, the bottom inside of upper flange 1 is provided with transition arc 3.
