Description
Technical field
The utility model is related to the wind turbine towers of a kind of wind power generation stepped more particularly to a kind of grouting connection.
Background technology
Wind-driven generator tower frame is the important component of wind power plant, at present mainly using steel cylinder or slightly
Circular cone type structure.Every section of steel tower tube is individually built in factory, and then every section of steel tower tube is transported to infield and is assembled.
Many wind field mean wind speeds leaved for development are relatively low at present in China, and it is more preferable that high tower can allow wind power plant to obtain
Wind energy improve generated energy.Pylon is higher, and the design size of structure is also bigger, it is meant that wall thickness or diameter should increase.
According to gained is calculated, it is more beneficial than wall thickness to increase tower diameter.But it is multiple by transportation clearance, overall frequency, economy etc.
The tower that the limitation of factor is traditional can no longer meet requirement.
In order to solve transportation problem, there is split blade type wind turbine tower.Ready-made steel tower is cut in factory,
Assembling is bolted at the scene.But this bolted split blade type pylon Assembling is difficult, and stress is complicated, bad dimension
Shield.
In prior art specific implementation process, there is following problem：
(1) after traditional tower does height, frequency and bearing capacity can only be improved by increasing wall thickness or increasing diameter.
Increasing wall thickness can be such that tower weight increases very much, lose economy；Increasing diameter can be limited by traffic condition.
(2) bolted split blade type pylon Assembling is difficult, and the use of a large amount of bolts keeps pylon stress complicated, the later stage
It safeguards relatively difficult.
Utility model content
In view of the drawbacks described above of the prior art, the technical problem to be solved by the utility model is to provide a kind of grouting companies
The wind turbine tower connect, wherein including：The superposition installation of multilayer tower, the tower include：Multi-disc tower piece goes up phase from longitudinal
It is mutually spliced into tubular, tower piece two opposite sides side is equipped with multistage sleeve, after two adjacent tower piece splicings, multistage
The sleeve is spliced into a fixing pipe by joining end to end；One connection mandrel passes through the fixing pipe, the connection mandrel and institute
Grout filling between fixing pipe is stated, gasket seal is equipped between the two adjacent sleeves of the fixing pipe.
Preferably, the opening of the tower two is welded with flange, and the two adjacent towers pass through the flanged joint.
Preferably, the connection mandrel is equipped with multiple locating piece groups, and the locating piece group includes being welded on the connection
Multiple locating pieces on the same longitudinal section of mandrel；The locating piece offsets with the fixed inside pipe wall.
Preferably, the sleeve is welded on the tower on piece by support leg.
The wind turbine tower of the utility model grouting connection efficiently solves and leads in the prior art compared to the prior art
The problem of of high cost, transport is difficult, installation is inconvenient, Maintenance Difficulty caused by increasing the scheme that tower thickness is increased is spent, tower piece is passed through
Splicing construction, splice the staggered formation fixing pipe of after sleeve in tower piece, and connection mandrel and filling is passed through in fixing pipe
Slurry filling so that connecting shaft is integrally formed with fixing pipe, to overcome the limitation of size, can be spliced as needed,
Assembling is easy, and stress is preferable, is easy to safeguard.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.

Specific implementation mode
As shown, Fig. 1 is the structural schematic diagram of the splicing part of the two tower pieces of the utility model, a kind of grouting connection
Wind turbine tower, wherein including：The superposition installation of multilayer tower 1, tower 1 include：Multi-disc tower piece 2 is upper mutual from longitudinal direction
It is spliced into tubular, two adjacent tower pieces 2 can splice in the horizontal direction；2 two opposite sides side of tower piece is equipped with multistage set
Cylinder 4, after two adjacent tower pieces 2 splice, multistage sleeve 4 is spliced into a fixing pipe by joining end to end；One connection mandrel 5 passes through
Fixing pipe connects grout filling between mandrel 5 and fixing pipe, and the axis that connects with the heart forms integral structure with fixing pipe, realizes that two is adjacent
Tower piece 2 fixation, two panels tower piece 2 can be spliced into tower 1, by the way of the splicing of more tower pieces 2 can also be used, root
Flexibly spliced according to different needs；Gasket seal 6 is equipped between two adjacent sleeves 4 of fixing pipe.
Fig. 4 is the structural schematic diagram of the tower of the utility model, and further, 1 liang of tower, which is open, is welded with flange 3, two
