Abstract
The utility model discloses a connecting structure for a tower drum and a foundation of a wind generating set, in particular to a foundation reinforcing cage used for connecting a tower drum and a foundation of a wind generating set. The foundation reinforcing cage of the wind generating set consists of an upper connecting pad (2), a lower connecting pad (3), an annular cage structure formed by double-end studs (1) arranged between the upper connecting pad (2) and the lower connecting pad (3), and an adjusting pad (4) assembled on the lower connecting pad (3). The foundation reinforcing cage of the wind generating set can effectively reduce the defects of the traditional foundation ring processing way like time and effort wasting, high requirement on processing precision, etc. The foundation reinforcing cage way is adopted, which is simple, reduces the requirements, and does not need welding procedure; moreover, the weight of the foundation reinforcing cage is light; the split type structure of the foundation reinforcing cage is convenient for transportation; the strength of the foundation reinforcing cage is improved as the foundation reinforcing cage is connected by a high strength bolt; and the safety of the tower drum of the wind generating set is improved.
Description
Technical field
The utility model relates to a kind of wind power generating set tower tube and foundation connection structure, relates in particular to a kind of wind power generating set tower tube and strengthens cage with basic the connection with ground.
Background technique
Wind power generating set tower tube links to each other with ground by a connection set, and traditional connection set is a foundation ring, selects steel sheet material for use, by rolling plate, finishes processing by welding process after making sheet material become tubbiness.This processing mode is consuming time, consumption power, the requirement on machining accuracy height, the foundation ring weight of formation is big, be difficult for transportation, and because the welded structure changes of section is big, and transition region is steeper, the fillet smaller part causes that easily bigger stress is concentrated, welding process is kept away unavoidable existence welding residual thermal stress simultaneously, and the microstructure of the weld seam that produces of welding process, heat affected zone etc. has significant difference with the matrix of sheet material, cause insufficient strength, and it is relatively more difficult that the lightning protection line is installed in foundation ring.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of wind power generating set ground to strengthen cage, and purpose is that its processing mode is simplified, its weight is reduced, be convenient to transportation, improve intensity, the convenient lightning protection line of installing, and the Security that improves wind power generating set tower tube.
For achieving the above object, the utility model is achieved through the following technical solutions:
The wind power generating set ground is strengthened cage, and it is by last land, following land, is located at the annular cage structure that the stud between land and the following land constitutes, and on the following land assembling adjustment disk is installed.
The aperture nut that described stud upper end is passed on the land is connected and fixed, and the aperture nut that the stud lower end is passed down on the land is connected and fixed.
Described stud is the 120-200 root.
Described land and the following land gone up is that steel plate by two semicircular disk-like structures docks by bolt and constitutes.
Described assembling adjustment disk is by the base plate that is positioned at the bottom, is located at the bolt on the base plate and 3 nuts being located on the bolt constitute, and the nut that is positioned at the bottom is fixedlyed connected with base plate.
Advantage of the present utility model and effect:
It is consuming time to adopt the utility model can effectively reduce traditional foundation ring processing mode, consumption power, and the requirement on machining accuracy height, the foundation ring weight of formation is big, be difficult for transportation, and intensity is not high, and shortcomings such as lightning protection band difficulty are installed in foundation ring.Adopt the utility model ground to strengthen cage, its processing mode is simplified, and requires to reduce, and does not carry out welding process, and it is in light weight that ground is strengthened cage simultaneously, and its split-type structural is convenient to transportation, and bolt connects improves its intensity, improves the Security of wind power generating set tower tube.Land adopts split-type structural up and down, make install and transportation all very convenient, also made things convenient for simultaneously and being connected of foundation and tower tube part.Aspect lightning protection,, make the lightning protection line be installed in ground very easily and strengthen on the cage because ground is strengthened the hollow structure of cage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of assembling adjustment disk among Fig. 1.
Among the figure, 1, stud, 2, go up land, 3, land down, 4, the assembling adjustment disk.
Embodiment
Following structure accompanying drawing is described in further details the utility model, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the utility model wind power generating set ground is strengthened cage, it is by last land 2, following land 3, is located at the annular cage structure that the stud 1 between land 2 and the following land 3 constitutes, assembling adjustment disk 4 is installed on the following land 3, the aperture nut that stud 1 upper end is passed on the land 2 is connected and fixed, and the aperture nut that stud 1 lower end is passed down on the land 3 is connected and fixed.
Above-mentioned stud 1 is the 120-200 root.Land 2 and following land 3 are that the steel plate by two semicircular disk-like structures docks by bolt and constitutes.
Be illustrated in figure 2 as the assembling adjustment disk, seat leg when when the assembling ground is strengthened cage, playing ground and strengthening cage and link to each other with the basis, play the mount ground and strengthen the cage effect, it by the base plate that is positioned at the bottom, be located at the bolt on the base plate and 3 nuts being located on the bolt constitute, the nut that is positioned at the bottom is fixedlyed connected with base plate.
Assembly process of the present utility model:
After the basis is carried out, the basis reinforcement cage that will assemble by the assembling regulator plate is fixed on the basis, connect the lightning protection band, the lower flange bolt hole of tower tube is aimed at ground strengthen on the stud of cage upper end land, by nut the tower tube is fixed on ground and strengthens finishing connection on the cage.
