Description
Technical field
It the utility model is related to wind power generation stepped technical field, and in particular to a kind of wind power generation stepped steel pipe purlin of lattice
Frame and the connection structure of diameter fan tower.
Background technology
Wind generating technology takes up an area less, clean environment firendly, increasingly becomes state key development field without fuel.Wind-force
Generate electricity pylon as generator supporting member, it is necessary to light and handy and firm, can guarantee that stronger bearing capacity, and take into account economy into
This.
For lattice wind turbine tower, it is important to connect the transition segment of lattice steel pipe truss and blower fan tower barrel
Structure, stress is big and concentrates, therefore in the design of lattice wind tower, the connection transition of steel pipe truss and blower fan tower barrel is lattice
The difficult point of formula wind tower design.
Utility model content
The purpose of this utility model is to provide a kind of connection structure so that the type of attachment of lattice steel pipe truss and tower
Simply, power transmission is direct.
The technical solution of the utility model is as follows：
The connection structure of a kind of wind power generation stepped steel pipe truss of lattice and tower, it is characterised in that in steel pipe truss
It is connected between tower by transition segment；The steel pipe truss has multiple steel pipe king-posts, and the upper end of each steel pipe king-post is opened
There is U-shaped groove, the barrel of transition segment is inserted into U-shaped groove, and steel pipe king-post is fixedly connected with by butt weld；In U-shaped groove
Leave hole in bottom；Transition segment barrel is provided with semicircle groove between two steel pipe king-posts.
The steel pipe truss that the lattice of the utility model is wind power generation stepped includes steel pipe king-post, cross bar and brace, the steel
Tower column has n roots, is connected in the horizontal direction by cross bar each other, and side is connected by brace, and composition cross section is positive n sides shape
