Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to an auxiliary tooling for welding wind turbine tower flanges. Background Technology

[0002] With the increasing popularity and widespread application of wind power generation, its supporting facilities are also gradually being improved, and wind turbine towers are one of the important facilities among them. A wind turbine tower is assembled from multiple tower sections, which not only provide support but also absorb vibrations from the turbine. These tower sections need to be connected via flanges at their ends, thus requiring flange welding equipment. Current technology mostly uses hoisting devices to align the flanges with the tower ends for welding, but due to the large diameter of the flanges, operating the hoisting devices is quite inconvenient.

[0003] Existing technologies, such as Chinese Patent No. CN221516746U, disclose an auxiliary tooling for welding wind turbine tower flanges. This utility model fixes flanges of different specifications by adjusting the position of four sets of fixing plates, and then uses the meshing transmission of gears and racks to adjust the height of the flanges so that the center of the tower and the flange are aligned, which facilitates subsequent welding operations.

[0004] However, the above-mentioned utility model uses a motor to drive a gear to move a rack up and down to adjust the height of the flange. This may take a long time to align the center of the tower and the flange, and the accuracy of the center alignment is not high. This may result in a large error that affects the quality of the finished product. Therefore, this needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tooling for welding wind turbine tower flanges, which solves the problem that it is not easy to quickly and accurately align the centers of the tower and flange during welding.

[0006] To achieve the above objectives, this utility model provides an auxiliary tooling for welding wind turbine tower flanges, including a placement base, a tower, and a flange. The tower is disposed on the surface of the placement base, and the flange is disposed on one side of the tower.

[0007] It also includes positioning components;

[0008] The positioning assembly includes a movable platform disposed on the surface of a placement seat. A telescopic platform is slidably connected to the inner wall of the movable platform. A sleeve is fixedly connected to the surface of the telescopic platform. A rotating frame is rotatably connected to the inner wall of the telescopic platform. A vortex groove is formed on the surface of the rotating frame. A sliding groove is formed on the inner wall of the sleeve. A slider is slidably connected to the surface of the sliding groove. The slider is slidably connected to the surface of the vortex groove. A positioning frame is slidably connected to the inner wall of the sleeve. A placement frame is fixedly mounted on the surface of the positioning frame. A spring is fixedly connected to the surface of the positioning frame and is fixedly connected to the inner wall of the sleeve. A handwheel is fixedly connected to the surface of the rotating frame.

[0009] The slide, slider, positioning frame, placement frame and spring are all in four sets. The positioning frame cooperates with the slider. The flange is set on the surface of the placement frame. The placement frame is provided with different specifications.

[0010] The surface of the movable platform is provided with auxiliary components, including a mounting frame. The mounting frame is fixedly connected to the surface of the movable platform, and a slide rod is slidably connected to the inner wall of the mounting frame. A toothed plate is fixedly connected to the surface of the slide rod.

[0011] The rotating frame has a gear fixedly connected to its surface, and the gear plate meshes with the surface of the gear.

[0012] The mounting bracket has a screw hole on its surface, and a screw is threaded onto the surface of the screw hole. The screw engages with the toothed plate.

[0013] The slide rod is fitted with a second spring, one end of which is fixedly connected to the surface of the mounting bracket, and the other end of which is fixedly connected to the surface of the toothed plate.

[0018] This utility model discloses an auxiliary tooling for welding flanges on wind turbine towers. By setting up a positioning component, the tower is first placed on a placement seat. A corresponding placement frame is selected according to the flange specifications and installed on the positioning frame. The flange is then placed through the placement frame. Next, the movable platform is moved close to the tower, allowing the positioning frame to extend into the tower. Turning the handwheel rotates the rotating frame, using a vortex groove to drive four sets of sliders to slide along the groove, pushing the positioning frame and tightening spring one. As the four sets of positioning frames gradually press against the inner wall of the tower, the four sets of placement frames press against the inner wall of the flange, fixing the flange. Furthermore, because the telescopic platform and the movable platform are slidably connected, the telescopic platform also moves up and down, automatically aligning the tower and flange at their centers. By setting up the positioning component, flanges of different specifications can be fixed, and the centers of the tower and flange can be quickly and accurately aligned, improving the welding efficiency of the flange and effectively enhancing the convenience of the equipment.

[0029] The specific settings and functions of its positioning and auxiliary components will be discussed below.

[0030] In this embodiment: the positioning component includes a movable platform 201, which is disposed on the surface of the placement base 101. A telescopic platform 202 is slidably connected to the inner wall of the movable platform 201. The telescopic platform 202 and the movable platform 201 are provided so that when the four sets of positioning frames 208 gradually abut against the inner wall of the tower 102, the telescopic platform 202 can be moved accordingly, aligning the centers of the tower 102 and the flange 103. A sleeve 203 is fixedly connected to the surface of the telescopic platform 202. A rotating frame 204 is rotatably connected to the inner wall of the telescopic platform 202. A vortex groove 205 is formed on the surface of the rotating frame 204. A sliding groove 206 is formed on the inner wall of the sleeve 203. A slider 207 is slidably connected to the surface of the sliding groove 206. The slider 207 is slidably connected to the surface of the vortex groove 205. The rotating frame 204, vortex groove 205, sliding groove 206, and sliding... Block 207 is designed so that when the rotating frame 204 rotates, the vortex groove 205 drives the four sets of sliders 207 to move synchronously along the slide groove 206 away from the center. The inner wall of the sleeve 203 is slidably connected to the positioning frame 208. The positioning frame 208 is set so that when the slider 207 moves, it pushes the positioning frame 208 to gradually press against the inner wall of the tower 102 to achieve positioning. The surface of the positioning frame 208 is fixedly installed with the placement frame 209, which is set to place the flange 103. The surface of the positioning frame 208 is fixedly connected with the spring 210, which is fixedly connected to the inner wall of the sleeve 203. The spring 210 is set so that the positioning frame 208 can be reset so that it can be removed after positioning. The surface of the rotating frame 204 is fixedly connected with the handwheel 211, which is set so that the rotating frame 204 can be rotated.

[0031] Specifically, there are four sets of slide rails 206, sliders 207, positioning frames 208, placement frames 209, and springs 210. The four sets of positioning frames 208 and placement frames 209 are provided to facilitate the clamping of the inner walls of the tower 102 and flange 103 from four directions. The positioning frames 208 cooperate with the sliders 207. The flange 103 is placed on the surface of the placement frames 209. The placement frames 209 are provided with different specifications to facilitate the placement of flanges 103 of different specifications.

[0032] Specifically, the surface of the movable platform 201 is provided with auxiliary components, including a mounting frame 301. The mounting frame 301 is fixedly connected to the surface of the movable platform 201. A slide rod 302 is slidably connected to the inner wall of the mounting frame 301. The slide rod 302 is provided to guide and limit the movement of the toothed plate 303. The toothed plate 303 is fixedly connected to the surface of the slide rod 302. The toothed plate 303 is provided to cooperate with the gear 304 to fix the rotating frame 204.

[0033] Specifically, a gear 304 is fixedly connected to the surface of the rotating frame 204, and the gear plate 303 meshes with the surface of the gear 304. The gear 304 is set to cooperate with the gear plate 303. When the gear plate 303 and the gear 304 are pressed together, the rotating frame 204 is fixed to prevent it from rotating at will. When the gear plate 303 and the gear 304 are disengaged, the rotating frame 204 can rotate freely.

[0034] Specifically, the mounting bracket 301 has a screw hole 305 on its surface, and a screw 306 is threaded onto the surface of the screw hole 305. The screw 306 cooperates with the toothed plate 303. The screw hole 305 and the screw 306 are provided to facilitate the fixing of the toothed plate 303, prevent it from moving at will, and increase the stability of the structure.

[0035] Specifically, a second spring 307 is sleeved and connected to the surface of the slide bar 302. One end of the second spring 307 is fixedly connected to the surface of the mounting bracket 301, and the other end of the second spring 307 is fixedly connected to the surface of the toothed plate 303. The second spring 307 is provided to utilize its rebound effect to facilitate the toothed plate 303 moving away from the gear 304.

[0036] Specifically, the surface of the placement seat 101 is provided with a guide rail 308, and the surface of the movable platform 201 is rotatably connected with a roller 309. The roller 309 is slidably connected to the surface of the guide rail 308. The guide rail 308 and the roller 309 are provided to facilitate the movement of the movable platform 201 so that the flange 103 can be placed on the placement frame 209 and the positioning frame 208 can be easily extended into the tower 102.

[0037] Specifically, a handle 310 is fixedly connected to the surface of the movable platform 201. The handle 310 is provided to facilitate the movement of the movable platform 201. A positioning rod 311 is slidably connected to the inner wall of the handle 310. A positioning hole 312 is provided on the surface of the guide rail 308. The positioning rod 311 and the positioning hole 312 are provided to facilitate the fixation of the movable platform 201, so that the flange 103 is pressed against the tower 102, and to prevent it from moving randomly during welding.

[0038] Specifically, the positioning rod 311 is inserted into the surface of the positioning hole 312. The number of positioning holes 312 is multiple and evenly distributed. The purpose of setting multiple sets of positioning holes 312 is to facilitate the fixing of the movable platform 201 in different positions so as to adapt to towers 102 of different specifications.

[0039] Specifically, a spring 313 is fixedly connected to the surface of the positioning rod 311. The spring 313 is fixedly connected to the surface of the handle 310. The purpose of setting the spring 313 is to both lock the positioning rod 311 into the positioning hole 312 and to facilitate the reset of the positioning rod 311 by utilizing its rebound effect.

[0040] Working principle: By setting up the positioning components, the tower 102 is first placed on the placement seat 101. A corresponding placement frame 209 is selected according to the flange 103 specifications and installed on the positioning frame 208. The flange 103 is then passed through the placement frame 209. Next, the movable platform 201 is brought close to the tower 102, allowing the positioning frame 208 to extend into the tower 102. The handwheel 211 is turned to rotate the rotating frame 204. The vortex groove 205 drives four sets of sliders 207 to slide along the slide groove 206, pushing the positioning frame 208 and tightening the spring 210. As the four sets of positioning frames 208 gradually move... The four sets of placement racks 209 gradually press against the inner wall of the tower 102 and the inner wall of the flange 103, fixing the flange 103 in place. Since the telescopic platform 202 is slidably connected to the movable platform 201, the telescopic platform 202 will also move up and down, automatically aligning the tower 102 and the flange 103 with their centers. By setting up positioning components, flanges 103 of different specifications can be fixed, and the centers of the tower 102 and the flange 103 can be quickly and accurately aligned, improving the welding efficiency of the flange 103 and thus effectively enhancing the convenience of the equipment.

[0041] Furthermore, by setting auxiliary components, the gear 304 is fixed by the toothed plate 303, thus keeping the rotating frame 204 fixed when it does not need to rotate. If it is necessary to rotate the rotating frame 204, simply rotate the screw 306 to move it along the screw hole 305, so that the screw 306 no longer pushes the toothed plate 303. Under the rebound action of the second spring 307, the toothed plate 303 and the slide rod 302 are driven downward, so that the toothed plate 303 disengages from the gear 304, and the rotating frame 204 can then rotate. Subsequently, simply rotate the screw 306 in the opposite direction to push the toothed plate 303 to continue to clamp the gear 304 and tighten the second spring 307. In addition, to facilitate the placement of the flange 103 on the placement frame 209 and to facilitate the insertion of the positioning frame 208 into the tower 102, a guide rail 308 and rollers 309 are provided to facilitate the movement of the movable platform 201. To ensure the flange 103 is firmly against the tower 102 and prevent movement during welding, a positioning rod 311 and a positioning hole 312 are used to fix the movable platform 201. Simply pull the positioning rod 311 to disengage it from the positioning hole 312 and tighten the spring 313, then the movable platform 201 can be moved using the handle 310. After releasing the positioning rod 311, the positioning rod 311 returns to its original position under the rebound of the spring 313 and engages with the corresponding positioning hole 312, thus fixing the movable platform 201. By setting up auxiliary components, it is easy to fix the rotating frame 204 to prevent it from rotating arbitrarily, and it is also easy to move and fix the movable platform 201, so that the flange 103 can be firmly against the tower 102 and prevent movement during welding, thereby effectively improving the stability of the equipment.

[0042] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
