Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected or be integrally connected,
Can be mechanically connected or be connected directly, can also be indirectly connected by intermediary, can be inside two elements
Connection.For the ordinary skill in the art, above-mentioned term in the present invention specific can be understood with concrete condition
Meaning.
It is coaxial between each tower section during to ensure tower installation, and accelerate the installation speed of tower, it present embodiments provides
A kind of levelling device easy to operate, accuracy is high and method.Specifically arranged between two layers of tower section up and down of docking
The tower device for installing and leveling of several the present embodiment, and using leveling method provided in this embodiment fast and accurately to tower
Section carries out leveling.
As shown in Figure 1, the tower device for installing and leveling of the present embodiment, including wedge base 1 and wedge-shaped adjusting block 2, wedge shape
Adjustment block 2 is placed in wedge base 1, and the upper surface of wedge base 1 and the lower surface of wedge-shaped adjusting block 2 are equipped with, and wedge shape is adjusted
The top of monoblock 2 is set as arc-shaped curved surface, is contacted between upper strata Ta Jie 41 for line, can greatly reduce wedge-shaped adjusting block 2 and upper strata
Frictional force between tower section.Adjusting part is connected between wedge base 1 and wedge-shaped adjusting block 2, for adjusting wedge-shaped adjustment
The height of 2 opposite wedge pedestal 1 of block.
Specifically, adjusting part includes adjusting bolt 31 and locking nut 32,1 end of wedge base is equipped with card slot, wedge shape
2 end of adjustment block is correspondingly provided with threaded hole, and 311 one end of screw rod of adjusting bolt 31 is spun in the threaded hole of wedge-shaped adjusting block 2,
The other end is placed in card slot, and the bolt head 312 of adjusting bolt 31 is placed in the outside of card slot, and spanner easy to use carries out rotation behaviour
Make.Locking nut 32 is spun on screw rod 311, is placed in the inside of card slot.
Further, wedge base 1 and 2 middle part of wedge-shaped adjusting block are equipped with opening, can both reduce 2 top surface of wedge-shaped adjusting block
With the length of 41 contact lines of upper strata Ta Jie, have the function that reduce frictional resistance, can also mitigate the overall weight of levelling device, drop
Low material cost.
As shown in Figure 2 and Figure 3, when tower is installed, after upper and lower two layers of tower section is docked, leveling behaviour is carried out to upper strata Ta Jie 41
Make, be as follows：
S1 is evenly arranged several above-mentioned towers installation leveling on the circumference between upper strata Ta Jie 41 and lower floor's tower section 42
Device.
S2 judges whether to coarse adjustment according to the gradient of upper strata Ta Jie 41 and puts down, if gradient is more than predetermined value, first carries out
Thick leveling step S3, then perform smart leveling step S4；If gradient is less than or equal to predetermined value, smart leveling step is directly performed
S4。
S3 adjusts backing plate 5, by upper strata tower being added below tower device for installing and leveling of the upper strata Ta Jie 41 compared with downside
That saves is padded compared with downside；Wherein, the quantity of the adjusting backing plate 5 of required addition and thickness are true according to the gradient of upper strata Ta Jie 41
It is fixed.
S4 adjusts the tower device for installing and leveling compared with downside in upper strata Ta Jie 41, the relatively downside of upper strata Ta Jie is turned up；
Or, the tower device for installing and leveling in 41 upper sides of upper strata Ta Jie is adjusted, the upper side of upper strata Ta Jie is turned down；
Especially by the adjusting bolt 31 of rotation tower device for installing and leveling, 2 opposite wedge pedestal 1 of wedge-shaped adjusting block is adjusted
Height, the height of upper strata Ta Jie 41 is adjusted with realizing.
Since 2 top surface of wedge-shaped adjusting block of tower device for installing and leveling is arc-shaped curved surface, tower device for installing and leveling is set on
When between upper and lower two layers of tower section, contacted between the top surface of wedge-shaped adjusting block 2 and upper strata Ta Jie 41 for line, wedge-shaped tune can be greatly reduced
Frictional force between monoblock 2 and upper strata Ta Jie 41 so that rotating the operation of adjusting bolt becomes Portable power saving.
S5 judges whether upper strata Ta Jie 41 is whole and reaches horizontality, if so, operation terminates；Otherwise step S3 is returned to.
The present embodiment is rationally used in Levelling operation, according to the actual inclination of tower section and adjustment leveling method, when inclining
When gradient is smaller, can smart Levelling operation directly be carried out using the tower device for installing and leveling of the present embodiment, realize final leveling；And
It is reasonably combined at this time to use coarse adjustment quadratic method to make up the slightly aobvious slower deficiency of the flat service speed of accurate adjustment when gradient is larger,
The padded tower section of adjusting backing plate of different-thickness, side are added directly below tower device for installing and leveling of the upper strata Ta Jie compared with downside
Method is simpler quick.Gradient adjust to it is sufficiently small when, then final leveling realized using smart Levelling operation.
The present embodiment tower leveling method is flexibly practical, cooperation the present embodiment tower device for installing and leveling use, it can be achieved that
Quick, accurate leveling to tower section.And the wedge-shaped adjusting block top surface of the present embodiment tower device for installing and leveling is designed as arc song
Face contacts for line with upper strata Ta Jie, can greatly reduce frictional force between the two so that and Levelling operation becomes Portable power saving,
Levelling operation could be carried out without upper strata Ta Jie is sling, greatly improves the efficiency of tower installation.
On this basis, the present embodiment additionally provides wind power generating set, including what is be made of the superposition of at least two tower sections
Tower is equipped with several above-mentioned tower device for installing and leveling between adjacent towers section, and each layer tower section is by using above-mentioned leveling
Method carries out leveling with the use of above-mentioned tower device for installing and leveling, and as above, details are not described herein again for advantage.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.In addition,
It will be appreciated by those of skill in the art that although some embodiments described herein include it is included certain in other embodiments
Feature rather than other feature, but the combination of the feature of different embodiments means to be within the scope of the present invention and shape
Into different embodiments.
