Background technique
Wind-power electricity generation is the main mode of Wind Power Utilization, and it is its development trend that generator set maximizes.The wind power generation stepped single-pipe tower barrel structure that is generally, Generator Set require the tower tube of larger diameter to bear upper load.But be subjected to the highway transport condition restriction, at present tower tube diameter can not be greater than 4.3 meters, thereby the development of Generator Set is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of wind generator tower tube longitudinal flange.
The wind generator tower tube longitudinal flange that the utility model proposes, form by barrel 1, longitudinal flange plate 2, high-strength bolt 3, leap plate 4 and transverse flange 8, wherein, barrel 1 is some, the both sides of every barrel 1 are provided with longitudinal flange plate 2, adjacent barrel 1 connects by the longitudinal flange plate 2 of its both sides, and wherein the below of longitudinal flange plate 2 one sides is provided with and mills arc groove 6, and the longitudinal flange plate 2 that links to each other passes by high-strength bolt 3 and mills arc groove 6 connections; Side top is respectively equipped with semi-circular recesses 5 and rubberised layer 7 between the longitudinal flange plate 2 that links to each other; The longitudinal flange plate 2 that is positioned at every barrel 1 both sides connects by transverse flange 8, and adjacent transverse flange 8 links to each other by crossing over plate 4.
In the utility model, adjacent transverse flange 8 is crossed over plate 4 by upper and lower two and is linked to each other.
In the utility model, longitudinal flange plate 2 should be avoided the bolt of transverse flange 8, and is continuous for guaranteeing transverse flange 8 rigidity, and two blocks of leap plates 4 up and down are set at longitudinal flange plate 2 places.
The utlity model has following beneficial effect:
1. major diameter tower tube burst is made, transported, assembled on site, installation make the development of Generator Set not restricted by highway transport, save major diameter tower tube cost of transportation simultaneously.
2. longitudinal flange adopts high-strength bolt to connect, and guarantees the strength and stiffness of connection, makes each sheet tower tube co-operation.
3. the longitudinal flange place is provided with transverse flange and crosses over plate, makes transverse flange rigidity continuous.
4. between the longitudinal flange plate arc-shaped gaps is arranged, make flange connect inside and outside both sides, back and can fit closely; After compressing, can play the two semicircle gluings at outer edge place the effect of sealing.

Fig. 2 is wind generator tower tube longitudinal flange and transverse flange cross connection pattern.
Number in the figure: 1 is barrel, and 2 is the longitudinal flange plate, and 3 is high-strength bolt, and 4 for crossing over plate, and 5 is semi-circular recesses, and 6 is the single face arc groove, and 7 is rubberised layer, and 8 is transverse flange.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: the utility model is made up of barrel 1, longitudinal flange plate 2, high-strength bolt 3, leap plate 4, semi-circular recesses 5, single face arc groove 6, rubberised layer 7 and transverse flange 8.The barrel 1 of tower tube is divided into some, longitudinal method plate 2 is contained in the both sides of every barrel 1, adjacent barrel 1 connects by the longitudinal flange plate 2 that is positioned at both sides, wherein longitudinal flange plate 2 single faces are provided with and mill arc groove 6, and the longitudinal flange plate 2 that links to each other passes by high-strength bolt 3 that to mill arc groove 6 fixedly connected; Side top is respectively equipped with semi-circular recesses 6 and rubberised layer 7 between the longitudinal flange plate 2 that links to each other; The longitudinal flange plate 2 that is positioned at every barrel 1 both sides connects by transverse flange 8, and adjacent transverse flange 8 links to each other by crossing over plate 4.Major diameter tower tube is divided into some and makes and be transported to the scene, makes each sheet be connected to complete tower tube by longitudinal flange and installs then.
The utility model construction sequence is as follows:
1. the tower tube is divided into 1 manufacturing of some barrels and is transported to the scene, and the both sides of every barrel 1 are provided with longitudinal flange plate 2, mill single face arc groove 6 on the longitudinal flange plate 2.
2. the two-sided rubberised layer 7 that is provided with on longitudinal flange plate 2.
3. adopt high-strength bolt 3 that each sheet barrel 1 is connected to complete tower tube, and couple together with the transverse flange 8 of high-strength bolt longitudinal flange plate 2 both sides with cross over plate 4 and reinforce temporarily.
4. tower tube hoisted in position, and dock with bottom tower tube transverse flange 8 usefulness high-strength bolts.
5. remove the interim reinforcing high-strength bolt of crossing on the plate 4, and change the permanent high-strength bolt of tower tube.
6. this longitudinal flange can only could be reinforced with crossing over plate in hoisting process when oppositely balance flange (patent No. ZL 2,006 2 0045883.9) is as transverse flange; Can not transversely strengthening when generally flange is as transverse flange.
