[0002] In order to facilitate transportation, transfer and storage, large-diameter towers are usually divided into three tower segments along the length of the tower. Before the tower is divided, a longitudinal flange needs to be welded inside the tower so that the three tower segments can be assembled into a complete tower through the longitudinal flange after the tower is divided.

[0003] At present, several bolt sleeve tools are required in the process of welding the longitudinal flange to the tower, such as the attached Figure 6 As shown, the bolt sleeve tooling includes a T-shaped sleeve and a bolt. The T-shaped sleeve is arranged between two longitudinal flanges, and the axis of the sleeve at the bottom of the T-shaped sleeve coincides with the axis of the flange hole on the longitudinal flange, and the bolt is passed through the two longitudinal flange plates and the sleeve for fastening. When installing the existing bolt sleeve tooling, it is necessary to fix a number of T-shaped sleeves by installing a number of nuts, and after welding, each bolt needs to be removed to dismantle the T-shaped sleeve, which has the problems of cumbersome construction steps, high labor intensity, and low efficiency.

[0004] Based on this, the present application provides a segmented tower longitudinal flange welding tool with simple construction steps and high efficiency, which can greatly reduce labor intensity. Utility Model Content

[0030] Embodiment 1

[0031] This embodiment provides a longitudinal flange welding tooling for segmented tower barrels. As shown in the attached Figure 1 and the attached Figure 2 figures, it includes a plurality of inner support plates 1 and two outer pressure plates 2. The inner support plates 1 are in a "T" shape, and their bottoms are inserted between two longitudinal flanges 3 to provide inner support for the two longitudinal flanges. The two outer pressure plates 2 are arranged on the outer sides of the two longitudinal flanges 3 to provide outer support for the two longitudinal flanges.

[0032] As shown in the attached Figure 4 figure, the two ends of the outer pressure plate 2 are provided with mounting holes 2.1 corresponding to the flange holes of the longitudinal flange, and the two ends of the two outer pressure plates 2 are tightened by bolts 4.

[0033] As shown in the attached Figure 3 and the attached Figure 4 figures, the top of the outer pressure plate 2 is provided with guide posts 2.2, and the inner support plates 1 are provided with guide grooves 1.1 slidably connected to the guide posts 2.2. The inner support plates 1 are movably connected to the outer pressure plates 2. Preferably, the cross-section of the guide posts 2.2 is circular, and the cross-section of the guide grooves 1.1 is in a "C" shape. This design can, on the one hand, assemble the outer pressure plate and the inner support plate into a whole, and at the same time, the inner support plate can also adjust its position along the outer pressure plate. Specifically, the inner support plates are arranged between the two longitudinal flanges at a set spacing; on the other hand, the outer pressure plate can rotate a certain angle relative to the inner support plate. As shown in the attached Figure 5 figure, this is beneficial to the installation of the longitudinal flange plate.

[0034] The welding tooling designed in this embodiment uses inner support plates and outer pressure plates to fix the longitudinal flange to ensure the positions of the two longitudinal flanges, and can also effectively prevent the deformation of the longitudinal flange during the welding process; several inner support plates and movable outer pressure plates are assembled together, which is convenient to adjust the position of the inner support plate along the outer pressure plate. The two outer pressure plates are only fixed by bolts at both ends, and only two bolts need to be operated for installation and disassembly, which can greatly reduce the labor intensity.

[0035] Preferably, as shown in the attached Figure 1 figure, the bottom width of the inner support plate 1 is equal to the spacing between the two longitudinal flanges 3 to ensure that the inner support plate forms effective support for the two longitudinal flanges and prevent the longitudinal flange from deforming during the welding process.

[0036] Preferably, there is a gap between the bottom surface of the inner support plate 1 and the bottom surface of the longitudinal flange 3, and the gap is equal to the width between the two longitudinal flanges. This design enables the welding rod to pass through the gap, so that the inner support plate does not interfere with the welding of the longitudinal flange, that is, the inner support plate does not need to be removed during welding.

[0037] Preferably, as shown in the Figure 4 accompanying drawings, at least one reinforcing rib 2.3 is further provided on the outer side of the outer pressing plate 2, which can effectively prevent the deformation of the inner support plate.

[0038] Preferably, as shown in the Figure 3 accompanying drawings, a circular hole 1.2 is further provided in the middle of each inner support plate 1, which is convenient for pulling out the inner support plate.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as shown in the Figure 1 and the Figure 3 accompanying drawings, a circular tube 1.3 is further welded to the bottom of the inner support plate 1, and the outer diameter of the circular tube 1.3 is equal to the width between the two longitudinal flanges 3. This design can further increase the support for the bottom of the two longitudinal flanges, and there is a gap between the weld of the circular tube and the two longitudinal flanges. Similarly, the welding rod can pass through the gap, so that the inner support plate does not interfere with the welding of the longitudinal flange, that is, the inner support plate does not need to be removed during welding.

[0041] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
