Description

[0002] Wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in wind turbine generator sets and absorbs the vibration of the set. The main process of tower production is raw material processing, plate rolling, and welding to form the shape of the tower. During the welding process, due to the large size of the tower itself, auxiliary tooling will be used to limit the tower to ensure the welding work. However, the existing auxiliary work still has the following problems:

[0003] Most of the existing welding tools are for arc welding with fixed structures. First, they can only adapt to one type of tower and cannot limit and fix different towers. Secondly, when the tower is limited, a crossbar is used to limit and support it in order to prevent the tower from deforming during use. However, the crossbar also has the problem of fixed size when used, and cannot adapt to different towers, so one set of fixed tools and crossbars are used for one set of towers, which is inconvenient to use. To this end, we propose an adjustable auxiliary tool for welding large-taper wind turbine tower sections to solve the above-mentioned problems. Utility Model Content

[0039] The following is combined with Figure 1-5 The utility model is described in further detail.

[0040] Embodiment 1, refer to Figure 1-3 In this embodiment, in order to solve the problem that the existing fixed tooling cannot adapt to different towers and the tower adjustment is difficult, the utility model discloses an adjustable auxiliary tooling for welding large-taper wind power tower sections.

[0041] It includes a tooling assembly 100, which also includes a tooling base 101, a limit block 102 is arranged above the tooling base 101, and a tower body 103 is arranged on one side of the limit block 102;

[0042] The fixing assembly 200 also includes a movable plate 201, which is located above the tooling base 101. Sliding blocks 206 are connected to both sides of the bottom of the movable plate 201. The sliding blocks 206 assist in supporting the movable plate 201 to prevent it from crushing the threaded rod 203. A threaded block 202 is connected below the center of the movable plate 201, and threaded rods 203 are connected to both sides of the threaded block 202. The movable plate 201 is driven to move by the threaded block 202 to adapt to tower bodies 103 of different sizes. A jack 204 is connected above the movable plate 201, and a fixed block 205 is connected above the jack 204. An extension rod 207 is connected below the fixed block 205. The extension rod 207 cooperates with the jack 204 to adjust the angle of the fixed block 205 to ensure the fixing effect.

[0043] The limit block 102 has a trapezoidal structure, and the center line of the limit block 102 coincides with the center line of the movable plate 201. The limit block 102 fits tightly against the tower body 103. The limit block 102 and the movable plate 201 are connected by hot-melt connection. The limit block 102 assists in limiting the tower body 103 to ensure its fixing effect.

[0044] Sliding blocks 206 are symmetrically distributed below the movable plate 201. The sliding blocks 206 are connected to the tooling base 101 in a sliding manner. The movable plate 201 forms a threaded structure with the threaded block 202 and the threaded rod 203. The threads on both sides of the threaded rod 203 are in opposite directions. The movable plate 201 cooperates with the threaded block 202 to move toward both sides to adapt to towers of different sizes. At the same time, the sliding blocks 206 provide auxiliary support to prevent the threaded block 202 from damaging the threaded rod 203.

[0045] Jacks 204 are evenly and equidistantly distributed above the movable plate 201. The connection between the jacks 204 and the fixed blocks 205 is a rotational connection. Extension rods 207 are symmetrically distributed on both sides of the fixed blocks 205. The fixed blocks 205 are symmetrically distributed on both sides of the tower body 103. The jacks 204 cooperate with the extension rods 207 to drive the fixed blocks 205 to adjust the angle, thereby assisting in adjusting the angle of the tower, so that the tower is in a horizontal state, which is convenient for welding.

[0046] The specific working principle is: first, during use, the tower body 103 is placed above the fixed block 205, and then the jack 204 is started, so that the jack 204 drives the two sides of the tower body 103 to rise or fall, so as to fit into the tower body 103, and as the jack 204 continues to rise and fall, it starts to drive the tower body 103 to rotate, so that the tower body 103 is in a horizontal state, and before the tower body 103 is placed, if it is too large or too small, turn on the drive motor on one side of the threaded rod 203, so that it drives the threaded rod 203 to move, so that the threaded rod 203 and the threaded block 202 undergo threaded motion, so that they move toward or opposite to each other, and drive the movable plate 201 to move, thereby changing the position of the fixed block 205 to adapt to different tower bodies 103.

[0047] Example 2, refer to Figure 1-2 In this embodiment, in order to solve the problem that the existing crossbar 301 cannot adapt to tower bodies 103 of different sizes, based on the same concept as the above-mentioned embodiment 1, the adjustable auxiliary tooling for welding large-taper wind power tower sections also includes:

[0048] The protection component 300 also includes a cross frame 301, which is located on the left side of the tower body 103. The outer side of the cross frame 301 is connected to an auxiliary block 303, and the inner side of the auxiliary block 303 is connected to a first adjustment block 304. The first adjustment block 304 cooperates with the auxiliary block 303 to change different lengths and adapt to tower bodies 103 of any size. A first connecting groove 3011 is opened on the inner side of the first adjustment block 304, and a connecting rod 305 is connected to the inside of the first connecting groove 3011. The first adjusting block 304 is limited by the cooperation of the connecting rod 305 and the first connecting groove 3011. Second connecting grooves 3012 are also opened on both sides of the connecting rod 305.

[0049] Auxiliary blocks 303 are symmetrically distributed on both sides of the crossbar 301. The connection between the auxiliary block 303 and the first adjusting block 304 is a sliding connection. The connection between the first adjusting block 304 and the threaded nail 302 is a threaded connection. The connection between the threaded nail 302 and the tower body 103 is a threaded connection. The auxiliary block 303 cooperates with the first adjusting block 304, so that the auxiliary block 303 has a retractable function, adapts to different towers, and ensures a fixing effect.

[0050] The inner side of the first adjusting block 304 is evenly and equidistantly provided with second connecting grooves 3012, the second connecting grooves 3012 are connected to the connecting rod 305 by threaded connection, the two sides of the connecting rod 305 are symmetrically provided with first connecting grooves 3011, the first connecting grooves 3011 are located on both sides above the auxiliary block 303, the connecting rod 305 cooperates with the first connecting groove 3011 and the second connecting groove 3012 to fix the first adjusting block 304, so as to prevent it from falling off during use and affecting the fixing effect of the tower.

[0051] The specific working principle is: as mentioned above, when the tower body 103 needs to be limited and fixed, the first adjustment block 304 is pulled out from the auxiliary block 303 until the outermost threaded nail 302 of the first adjustment block 304 can be threadedly fixed with the tower body 103, thereby completing the fixation. At the same time, the connecting rod 305 is grabbed and aligned with the first connecting groove 3011 and the second connecting groove 3012, and the connecting rod 305 is rotated so that it has a threaded movement with the first connecting groove 3011 and the second connecting groove 3012, completing the fixation of the first adjustment block 304 and preventing it from loosening, and fixing the other three first adjustment blocks 304 in sequence.

[0052] Example 3, refer to Figure 4-5 In order to solve the problem of thread wear caused by repeated use of the existing threaded nail 302 in this embodiment, based on the same concept as the above-mentioned embodiment 1, the adjustable auxiliary tooling for welding the large-taper wind power tower barrel section also includes:

[0053] The circulation component 400 also includes a second adjustment block 401, which is located on both sides of the cross 301. The outer side of the second adjustment block 401 is connected to a second auxiliary block 403, and the interior of the second auxiliary block 403 is also connected to a glue layer 405, which is connected to a second threaded sleeve 404 through the glue layer 405 to ensure its circulation disassembly, and the other side of the glue layer 405 is connected to the second threaded sleeve 404, and the outer side of the second adjustment block 401 is also connected to a first threaded sleeve 402, which protects the threaded nail 302 and prevents it from falling off.

[0054] The second adjusting block 401 is connected to the first threaded sleeve 402 by glue, and the first threaded sleeve 402 is connected to the threaded nail 302 by threaded connection. Glue layers 405 are evenly and equidistantly distributed on the inner side of the second adjusting block 401. The second adjusting block 401 cooperates with the first threaded sleeve 402 so that the threaded nail 302 can cyclically fix the second adjusting block 401 to avoid deformation of the tower due to loose threads during long-term use.

[0055] The number of glue layers 405 is consistent with the number of second connecting grooves 3012. The second connecting groove 3012 is glue-connected to the second threaded sleeve 404 through the glue layer 405. The second threaded sleeve 404 is also distributed inside the first connecting groove 3011. The second threaded sleeve 404 is connected through the glue layer 405, so that the second threaded sleeve 404 can be cyclically disassembled without causing damage to the second connecting groove 3012.

[0056] The specific working principle is: as mentioned above, during use, the threaded nail 302 is connected to the tower body 103 through the first threaded sleeve 402, and the second adjustment block 401 completes the limiting and fixing of the tower body 103 to prevent deformation. At the same time, because the second adjustment block 401 itself can adapt to different tower bodies 103, it will be frequently disassembled. When the threaded nail 302 is used too much and causes the thread inside the first threaded sleeve 402 to wear, the first threaded sleeve 402 can be taken out and replaced. At the same time, the connecting rod 305 is also the same. The second adjusting block 401 is fixed by the second threaded sleeve 404. When the thread is worn after long-term use, the second threaded sleeve 404 can be replaced.

[0057] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
