Abstract
The utility model relates to a tower drum structure and belongs to the technical field of wind power generation. The tower drum structure is formed by matching connection of at least two tower drum sections. The matching connection structure comprises an inner clamping plate, an outer clamping plate, bolts, nuts and a plurality of fixing seats. The bolts penetrate through a gasket, the inner clamping plate, tower drum walls and the outer clamping plate to be connected to the nuts arranged on the fixing seats. Each tower drum section is formed by combination connection of two or more than two arc-shaped piece type tower drum walls, and the adjacent piece type tower drum walls are in matched connection with each other. The two or more than two tower drum structure walls are assembled on site to form the tower drum section, a plurality of tower drum sections are in matched connection with each other to form the required tower drum, not only is transportation space saved, but also the transportation cost is reduced, in-plant production lifting is convenient, storage area on a factory is reduced, equipment limitation is reduced, and the large-diameter tower drum is easy to manufacture. The nuts connected with the bolts are fixed on the nut fixing seats, and influence on strength of a tower drum caused by rotation of the nuts is avoided.
Description
Technical field
The invention belongs to technical field of wind power generation, particularly relate to a kind of tower tube package assembly.
Background technique
Along with the development of wind generating technology, the single-machine capacity of wind power generating set is increasing, to the diameter of its supporting tower tube, highly have higher requirement.Major diameter, heavy weight tower tube need main equipment when making, and its cost, machining cost are improved; Since all limit decision of transportation aspect tower tube merogenesis connect, the farad that will be welded on tower tube two ends through bolt between present stage wind power generating set tower tube two joints links together.In wind power generating set tower tube production link, flange fabrication technology requires high, and the manufacture cycle is long, and cost is high.And during owing to flange and tower body welding, there is the welding residual thermal stress, thereby can causes the concentrated tower tube of stress to lose efficacy, even rupture at connection part.Storage space to manufacturer is also had higher requirement.These difficulties impact the development of wind-powered electricity generation industry, become a bottleneck in the wind-powered electricity generation industry development.
Summary of the invention
To the technical problem of above-mentioned existence, the present invention provides the tower tube package assembly of a kind of convenient transportation and assembling.
The objective of the invention is to realize through following technological scheme:
A kind of structure of tower tube of the present invention is: being connected by at least two tower shell rings constitutes; Its structure that is connected is: comprise inner splint, external splint, bolt, nut and a plurality of fixed base, bolt passes packing ring, inner splint, tower barrel, external splint and is connected on the nut that places fixed base.
Said tower shell ring adopts the formation that is connected of the arc chip tower barrel more than two or two, is connected between adjacent chip tower barrel.Said nut is fixed on the fixed base.Said inside and outside clamping plate and nut fixed base are the corresponding arc plate of arc with adjacent chip tower barrel joint.Said chip tower barrel joint all has the equidistance bolt hole that cooperates with bolt.
The another kind of structure of tower tube of the present invention: adopt arc chip tower barrel more than two or two formation that is connected, be connected between adjacent chip tower barrel.
Linkage structure between said adjacent chip tower barrel is: comprise inside and outside clamping plate, bolt, nut and a plurality of fixed base, bolt passes packing ring, inner splint, chip tower barrel, external splint and is connected on the nut that places fixed base.Said nut is fixed on the fixed base.Said inside and outside clamping plate and nut fixed base are the corresponding arc plate of arc with adjacent chip tower barrel joint.Said chip tower barrel joint all has the equidistance bolt hole that cooperates with bolt.
Beneficial effect of the present invention is:
1. the present invention forms the tower shell ring by the tower barrel assembled on site more than two or two; Again a plurality of tower shell rings are connected and form required tower tube, not only practice thrift transport space, and practice thrift cost of transportation; Make and produce lifting in the factory conveniently; Reduce an interior storage space, reduce device-restrictive, be easy to make major diameter tower tube.
2. the nut of connecting bolt of the present invention is fixed on the nut fixed base, prevents that nut from rotating, and it is connected closely with the tower barrel, strengthens tower tube intensity.
