Description
Technical field
The utility model is related to a kind of tower of wind power generating set, especially a kind of tower fragment connection structure belongs to
Fragment tower combination technique field.
Background technology
The tower of wind power generating set is made of the axially stacking connection of multiple tower segments, the diameter and height of each tower segments
Huge, transport is more difficult.In order to solve the problems, such as transport difficult, there are combined type tower segments, i.e., each tower segments are by multiple
Tower sheet body forms.Tower sheet body can be transported to wind field when construction, assembles tower segments in wind field, avoid tower segments transport not
Just the problem of.Interconnecting piece need to be arranged in the position connected between tower sheet body, to by the interconnection of interconnecting piece by tower piece
Body is assembled into tower segments.Tower is generally divided to 3 along longitudinal direction, fragment is connected integral tower segments by blending bolt.It is existing
There are mainly three types of connection types, the first uses the connection type of flange positioning anchor, as shown in Figure 1, disadvantage：Prior art needs
It improves, tower manufacturing process need to be planned again, and need hydraulic press that junction is shaped to straight section；And tower wall thickness
Different along longitudinal direction, plank baseline disunity is relatively difficult to achieve on packaging technology.The third adds the connection type of angle steel using flange,
As shown in Fig. 2, disadvantage：Asymmetric connection is not easy to implement welding procedure, and tower manufacturing process need to be planned again.The third is used
Flange adds the connection type of rigid gasket, a kind of wind turbine tower as disclosed in patent publication No. CN1759242B, the fragment of tower
It is welded with flange on junction, rigid gasket is placed in the interval between two flanges, with one flange of screw bolt passes
Connecting hole, rigid gasket through-hole, the connecting hole of another flange, as shown in Figure 3.This requires the intervals between two flanges
Distance and the thickness of rigid gasket must be consistent, and the connection hole site on two flanges must be consistent, this just gives welding
Very high requirement is proposed with Assembling technique.In addition, since there are errors for the circularity of the fragment of tower itself, using rigidity
It is difficult that the connecting hole on two flanges is made to be aligned when gasket splices, between the fragment of tower.Therefore, it welds with packaging technology very
Difference.
Invention content
The utility model proposes a kind of tower fragment connection structures, are designed using new Joining Structure, solve existing combination
The technical problem of the manufacture of formula tower and packaging technology difference.
To achieve the above object, the technical solution adopted in the utility model is：A kind of tower fragment connection structure, if including
A tower fragment, tower fragment segmentation portion are welded with longitudinal flange, are connected with elasticity between the longitudinal flange on two tower fragments
Fitting is fixedly connected with bolt, combines integral tower segments.
The spacing between longitudinal flange on described two tower fragments is adapted with the width of flexible connector.
The flexible connector is U-type groove steel, and connection through-hole is respectively equipped on the both sides of the U-type groove steel.
Longitudinal flange on described two tower fragments passes through the connection on the both sides of U-type groove steel logical by bolt respectively
It is used in combination nut check to fix in hole, wherein U-type groove steel and side bolt are pre-installed in factory on longitudinal flange, U-type groove steel
With other side bolt in wind field in-site installation.
The utility model has the beneficial effects that：
1. increasing longitudinal flange spacing, the influence welded to longitudinal flange is cut when reducing flame；
2. at fragment docking, longitudinal shear intensity at docking is improved；
3. connector belongs to local elasticity's connection structure, low to longitudinal flange flatness requirement.
4. flexible connector and side bolt are pre-installed in factory on longitudinal flange, only need to install at wind field scene
Other side bolt is convenient for wind field in-site installation.

Specific implementation mode
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 4, shown in 5, a kind of tower fragment connection structure, including first to third tower fragment 1,2,3, elastic connection
Part 4, bolt 5, longitudinal flange 6.Each tower fragment segmentation portion is welded with longitudinal flange 6, the longitudinal flange 6 on two tower fragments
Between be fixedly connected with bolt 5 with flexible connector 4, combine integral tower segments.
The spacing between longitudinal flange 6 on two tower fragments is adapted with the width of connector 4.Connector 4 is U-shaped
Channel steel is respectively equipped with connection through-hole on the both sides of U-type groove steel.Longitudinal flange 6 on two tower fragments is worn by bolt 5 respectively
The connection through-hole on the both sides of U-type groove steel is crossed, nut check is used in combination to fix.As shown in fig. 6, connector 4 and side bolt 5 are in work
Factory is pre-installed on longitudinal flange 6, only needs to install other side bolt 5 at wind field scene, pacify convenient for wind field scene
It fills, the arrow B in wherein Fig. 6 indicates installation direction.
The utility model adds connecting-piece structure as a result of longitudinal flange, increases longitudinal flange spacing, to reduce fire
The influence welded to longitudinal flange is cut when flame；It is low to longitudinal flange flatness requirement；It is easier in bolt hole pair, is convenient for wind field
Field-installed requirement；Meet the manufacturing process requirement of high-volume combined type tower.
