Abstract
The utility model discloses a self-positioning flange of a wind-driven power generation tower, which aims to facilitate connection of a suspended wind-driven power generation tower. The self-positioning flange of the wind-driven power generation tower comprises a flange body, the flange body is provided with a bolt hole and positioning pin holes, and positioning pins are arranged in the positioning pin holes. The positioning pins on the upper part of the flange can be inserted into the positioning pin holes on the lower part of the flange to realize rapid positioning and connecting. During connection, the longest positioning pin is inserted in the positioning pin hole on the lower part of the flange of the tower at first, the upper part of the tower is slightly adjusted, and then a longer positioning pin is inserted into the positioning pin hole on the lower part of the flange of the tower, thus the connection speed of suspending the tower in the air is increased greatly, and the construction is facilitated.
Description
Technical field
The utility model relates to the connection set of wind-power tower, and the self-align flange of particularly a kind of wind-power tower makes the skyborne wind-power tower of lifting easy to connect.
Background technique
Wind energy resources is a renewable energy sources, and utilizing wind energy power also is the new energy industry of world today's fast development.Wind-powered electricity generation is by the steel design tower generator to be placed in tens meters high aerial, and its wind energy is converted to the cover system that mechanical energy is converted to electric energy again.Land wind-powered electricity generation steel design tower generally is to make cylindrical tower tube or frustoconic shape tower tube with roll of steel plate, generally be divided into three sections, adpting flange is welded on the end at every joint tower tube two ends, by bolt flange is connected, the lower end of wind-powered electricity generation main frame also is to be connected with main barrel with flange, and whole tower tube highly reaches more than 70 meter.Every cover tower tube all wants the centering flange to connect construction 4 times aloft, and first segment connects twice between the tower tube after being connected with ground is basic, and main barrel is connected once with epimerite tower tube, and the wind-powered electricity generation main frame is connected once with main barrel.Each flange connects all bolts up to a hundred, and each joint tower tube and wind-powered electricity generation main frame all will carry out flange centering by bolt aloft and connect.Can imagine that tower tube or wind-powered electricity generation main frame that tons up to a hundred are heavy are suspended in tens meters in the air, the centering flange is worn the construction that bolt is the comparison difficulty.For convenient construction need improve flange arrangement.
Summary of the invention
The purpose of this utility model provides the self-align flange of a kind of wind-power tower, makes things convenient for the connection of wind-power tower, improves operating speed.
Can use the technical program for reaching above-mentioned purpose: the self-align flange of a kind of wind-power tower comprises flange body, is provided with bolt hole on flange body, also is provided with positioning pin hole on flange body, and locating stud is housed in it.Utilize the locating stud of upper flange to insert in the positioning pin hole of lower flange, realize being located by connecting fast.
Use the utlity model has following useful effect: the utility model has utilized the rigidity and the elasticity of unequal length locating stud, and mark or the ratio bolt hole of the diameter of positioning pin hole processing is big slightly is set on positioning pin hole, is convenient to identification.When connecting construction, locating stud that at first will be the longest inserts in the positioning pin hole of bottom tower drum flange.Adjust to go up the position of squarer tube a little, can insert in the positioning pin hole of bottom tower drum flange by the locating stud that the next one is long, accelerated the speed that the tower tube lifts connection aloft greatly, made things convenient for construction.
Description of drawings
Fig. 1 is an application principle schematic representation of the present utility model.
Fig. 2 is the plan view of the utility model structural representation.
Embodiment
Below in conjunction with example the utility model is done further detailed description: referring to Fig. 1 and Fig. 2, the self-align flange of a kind of wind-power tower comprises flange body 1, and flange body 1 is provided with bolt hole, also is provided with positioning pin hole on flange body 1, and locating stud 2 is housed in it.At least be provided with 2 locating studs 2 on the flange body 1,3 of preferred design, the length of locating stud 2 has nothing in common with each other, and is slotting the longest earlier, inserts one by one by the length difference.The diameter of positioning pin hole is convenient to distinguish identification, as shown in Figure 2 greater than bolt hole; Also can make positioning pin hole identical, be provided with mark, the convenient connection, need not special processing in the end of positioning pin hole with the diameter of bolt hole.The staff who stand in down in the squarer tube adjusts slightly to the tower tube that is hung in the top, can be with in the squarer tube under next locating stud 2 insertions, and convenient construction.
