Cylinder bottom end is both provided with gasket, and the bottom end of the upper tower madial wall is provided with upper flange plate, and the bottom end of upper flange plate is equal
Even to be fixed with stiffened panel, the top of the lower tower madial wall is equipped with lower flange plate, and the top of lower flange plate is uniformly pacified
Equipped with the mutually matched lower stiffened panel of upper stiffened panel, be all evenly arranged with screw hole on the upper flange plate and lower flange plate, and
High-strength bolt is mounted on screw hole between upper flange plate and lower flange plate, the both sides inside the lower tower are mounted on extension
Ring, and steel wire rope is respectively and fixedly provided on link, the both sides inside the upper tower are mounted on hook, and link up with remote with steel wire rope
One end connection from link.
Preferably, the upper tower bottom end angle with horizontal plane is in 30 degree, the bottom end on the top and upper tower of lower tower
It matches.
Preferably, the steel wire rope cross-fixing.
Preferably, the diameter of the charge door and compression leg is sequentially increased along clockwise direction, and the top of compression leg is respectively provided with
There is handle.
Preferably, it is fixed with rigidized cover on the outside of the high-strength bolt.
Compared with prior art, the utility model has the beneficial effects that：The tower cylinder connecting structure of wind generating set passes through
Steel wire rope, hook and link are installed so that the stability of device is stronger, is fixed by a variety of connection types so that apparatus structure
More stable, device is by being equipped with fixture block and card slot so that the docking of upper tower and lower tower is more acurrate, convenient for construction, and makes
The connection that tower and lower tower must be gone up is more stable, and device is by being equipped with gasket so that the better tightness of tower, device are logical
It crosses and rigidized cover is installed so that the intensity bigger of high-strength bolt, not easy to break, the safety higher used, device passes through installation
There are upper flange, lower flange, upper stiffened panel and lower stiffened panel, forms reversed balancing flange so that the length of high-strength bolt screw rod is not
It must rely on and increase flange thickness and increase, longer screw rod can store more elastic strain energies, anti-loosening property higher, in addition
Such flange need not survey torque coefficient due to not applying torque, do not have to apply molybdenum disulfide, therefore the friction coefficient of screw thread with
Traditional forged flange bolt is compared and is doubled, and fixed effect is more preferable.
