Abstract
The utility model discloses a connecting flange in a tower barrel, which is used for a large wind power generation device and belongs to pipeline connecting pieces. The connecting flange in the tower barrel comprises barrel sections, and flange rings and a plurality of stiffening plates which are arranged in the barrel sections; a plurality of bolt holes are arranged in the flange rings; the stiffening plates are arranged at the front sides of the flange rings; the front end surfaces of the stiffening plates are provided with balanced contact surfaces; the stiffening plates are provided with two to three positioning stiffening plates which comprise stiffening plates with grooves and stiffening plates with extending sections; the stiffening plates with the grooves are matched and connected with the stiffening plates with the extending sections for positioning; and the barrel sections are conical. In the connecting flange, the barrel sections and the barrel sections of the tower barrel have the same conical degree, the stress of the flange is improved, the assembly and the installment are easy, the installing difficulty is reduced, and the smooth transition of tower barrel connection is ensured, so that the overall tower barrel is attractive, and the quality is stable. Simultaneously, maintaining times of the tower barrel of the wind generator are reduced.
Description
Technical field
The utility model relates to a kind of flange arrangement, is specifically related to a kind of adpting flange that is used in the large-scale wind generating equipment tower tube, belongs to pipe joint.
Background technique
At present, the Connecting format of domestic all wind power generating set tower tube is traditional thick swaged forging part flange and connects, blower fan tower barrel generally is divided into three to four joints up and down, the taper shell ring that is welded by the roll of steel plate circle, because the position that thick swaged forging part flange is connected with the tower tube is the straight section shell ring, this has just brought very big difficulty to stack mounting, and the profile after the combination is also attractive in appearance inadequately.Adpting flange as the patent No. 200720002665.1, it comprises: flanged plate, a plurality of stiffened plate, shell ring, on flanged plate, be provided with a plurality of bolts hole, each stiffened plate is positioned at the front side of flanged plate, and the front-end face of stiffened plate is provided with the balance surface of contact, and this adpting flange welds together by straight section shell ring and tower tube.So the difficulty of stack mounting is big, the protruding phenomenon of tower tube combination part is more obvious, and this has just influenced the outward appearance of tower tube integral body greatly.
The model utility content
The purpose of this utility model is to overcome defective of the prior art, provide a kind of and can reduce the wind-power tower installation cost, group to, install easily, tower tube overall appearance is attractive in appearance, the adpting flange in the stay-in-grade taper tower tube.
For achieving the above object, the technical solution of the utility model has provided the adpting flange in a kind of tower tube, it is characterized in that, described flange includes shell ring, be arranged at flange ring and several stiffened plates on the shell ring inwall, be provided with bolt hole between several stiffened plates on the described flange ring, each stiffened plate is positioned at the front side of flange ring, and the front-end face of stiffened plate is provided with the balance surface of contact, in described bolt hole, bolt is housed, in described several stiffened plates, be provided with 2～3 location stiffened plates, described location stiffened plate comprises stiffened plate that is provided with groove and the stiffened plate that is provided with prolonged section, and the described stiffened plate that is provided with groove is cooperatively interacted with the stiffened plate that is provided with prolonged section to be connected; Wherein said shell ring be shaped as taper.
In the utility model, the tapering of described tower tube shell ring is identical.
In the utility model, described flange ring and stiffened plate all are welded on the inwall of described tower tube.
Advantage of the present utility model and beneficial effect are: because shell ring and tower tube shell ring are same tapering, flange stressed played the improvement effect, group to, install easy, reduced installation difficulty, guaranteed seamlessly transitting of tower tube connection, made tower tube overall appearance attractive in appearance, steady quality.Reduced simultaneously blower fan tower barrel freedom from repairs number of times.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The utility model is the adpting flange in a kind of tower tube, this flange includes shell ring 1, be arranged at flange ring 2 and several stiffened plates 3 on shell ring 1 inwall, between several stiffened plates 3 on the described flange ring 2, be provided with bolt hole 4, each stiffened plate 3 is positioned at the front side of flange ring 2, and the front-end face of stiffened plate 3 is provided with balance surface of contact 5, in described bolt hole 4, bolt 6 is housed, in described several stiffened plates 3, be provided with 2～3 location stiffened plate 3-1, described location stiffened plate 3-1 comprises stiffened plate 3 that is provided with groove and the stiffened plate 3 that is provided with prolonged section, the described stiffened plate that is provided with groove cooperatively interacted with the stiffened plate that is provided with prolonged section to be connected, to be used for the butt joint location of tower tube shell ring; Wherein said shell ring 1 be shaped as taper.And the tapering of described tower tube shell ring is identical.Described flange ring 2 all is welded on the inwall of described tower tube with stiffened plate 3.During installation, the taper shell ring 1 on the flange is welded as a whole with the tower barrel, adopts high-strength bolt 6 to connect in upper and lower section tower tube and gets final product.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
