The two burst wind power tower drums cut splicing and connect that the utility model proposes, described tower cylinder by some welding cylinder sections 6 from upper and on be welded, each welding cylinder section 6 is welded from top to bottom by some shell rings 9, each shell ring 9 is connected by some tower cylinder arc sheet 12 head and the tail and forms frustum cone structure, each shell ring 9 is provided with to erect cuts splicing plate 13 to two, laterally two splicing plate 14 of cutting cuts bolt 15 with two, the interior outside between tower cylinder arc sheet 12 adjacent on each shell ring 9 is uniform to be equipped with to erect and cuts splicing plate 13 to two, two bolt 15 of cutting is adopted to cut splicing plate 13 with erecting to two through tower cylinder arc sheet 12 successively, fastening two cut bolt 15 to make some tower cylinder arc sheets 12 form hoop rigidity intact, the welding cylinder section 6 of whole round platform.
In the utility model, the uniform ring of putting in the interior outside between tower cylinder arc sheet 12 in neighbouring welding cylinder section 6 cuts splicing plate 14 to two, adopting two bolt 15 of cutting to cut splicing plate 14 through tower cylinder arc sheet 12 with laterally two successively, fastening two bolt 15 of cutting makes welding cylinder section 6 up and down form certain flexural stiffness.
In the utility model, two splicing plate plate 14 ring of cutting of described transverse direction, to being divided into some, makes laterally two splicing plate 14 of cutting fit tightly with the upper and lower tower cylinder arc sheet 12 welded in cylinder section 6.
In the utility model, described tower cylinder is provided with door opening 5, the tower cylinder arc sheet 12 at described door opening 5 place is inside and outside arranges that stiffening plate 16 cut by doorframe pair, adopting two bolt 15 of cutting to cut stiffening plate 16 through tower cylinder arc sheet 12 and doorframe are two successively, fastening two bolt 15 of cutting makes that doorframe is two cuts the effect that stiffening plate 16 and tower cylinder arc sheet 12 play reinforcement.
The utility model advantage is:
1. providing the two burst tower cylinder cut splicing and connect of a kind of wind-force generating, tower cylinder vertical section and longitudinal burst all adopt two cuts connection, and doorframe adopts two cuts reinforcement. To tower cylinder burst, the transport of tower cylinder is unrestricted, can adopt major diameter, more efficient section form.
2. connection is cut in tower cylinder segmentation, longitudinal burst employing pair, and doorframe employing pair is cut reinforcement and can greatly be reduced tower cylinder welding capacity, it is to increase the anti-fatigue performance of structure, reduces welding distortion, it is ensured that the precision of the connection of tower cylinder and installation.
