Description

Technical Field

[0001] The utility model relates to the technical field of wind tower flanges, specifically a two-in-one wind tower flange with a locking structure. Background Art

[0002] Wind tower flange forgings are generally forged from S355NL steel (EN10025-3), which is a low-alloy high-strength structural steel with low carbon content. Manganese is the main strengthening element, and a small amount of grain-refining elements are added. The chemical composition and technical requirements of the steel for the offshore wind tower flange produced this time. In order to ensure the low-temperature toughness of the flange forgings, the phosphorus and sulfur content in the steel must be strictly controlled during steel smelting to effectively reduce the inclusion content in the steel.

[0003] The existing wind tower flange adopts an integrated structure, which is not easy to assemble by welding. The on-site welding process can easily cause thermal deformation of the wind tower flange, making it difficult to lock and install the wind tower flange as a whole. The on-site welding deformation causes installation deviation of the wind tower flange. Utility Model Content

[0004] The utility model aims to provide a two-in-one wind tower flange with a locking structure to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An inner locking assembly is mounted on the flange body;

[0008] An external lock assembly is arranged on the through bolt column;

[0009] Among them, a locking flange ring is provided at the penetration point on the flange body, connecting holes are distributed inside the locking flange ring, the through bolt thread penetrates the connecting holes and the locking flange ring, and a built-in flange ring is opened inside the flange body.

[0010] The two-in-one wind tower flange with a locking structure as described above: the locking flange ring fits and covers the outside of the flange body, and the through bolt is fastened inside the connecting hole.

[0011] The two-in-one wind tower flange with a locking structure as described above: the built-in flange is fastened to the locking flange ring by means of threads through the penetrating bolts.

[0012] The two-in-one wind tower flange with a locking structure as described above: the inner locking component includes a locking groove fixedly connected to the inner wall of the flange body, the inner side of the locking groove is provided with locking holes, and the outer side of the built-in flange is fixedly connected with a fastening ring.

[0013] The two-in-one wind tower flange with a locking structure as described above: the built-in flange is fastened to the locking groove through a fastening ring, and the fixing holes on the built-in flange are correspondingly mounted on the locking holes.

[0014] The two-in-one wind tower flange with a locking structure as described above: the external lock assembly includes a through column fixedly connected to the through bolt column, the through column thread is snap-fitted inside the connecting hole, and the limiting ring on the through column slides into the locking hole.

[0015] The two-in-one wind tower flange with a locking structure as described above: the through-column passes through the interior of the locking hole via a through-ring, and the through-ring can be deformed by collision and snapped onto the locking hole.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the flange body is assembled and fixed with the built-in flange through the locking groove, which can replace the integrated structure of the wind tower flange. It does not require on-site welding and assembly. The built-in flange and the flange body are fastened to each other, and the built-in flange is positioned and installed through the flange body. The assembled built-in flange can be welded on-site to prevent thermal deformation of the wind tower flange during the welding of the flange body.

[0017] The through ring that passes through the bottom end of the column passes through the locking hole, and at the same time passes through the flange body, the locking flange ring and the built-in flange. The through ring collides and deforms and fills into the locking hole, which is beneficial to the locking gap between the flange body, the locking flange ring and the built-in flange for sealing and filling. The wind tower flange is installed with overall locking. After locking, on-site welding is carried out. The locking flange ring and the built-in flange can be directly welded to prevent welding and installation deviation of the wind tower flange. BRIEF DESCRIPTION OF THE DRAWINGS
