[0002] Offshore wind turbine towers are tower-shaped steel structures used to support offshore wind turbine generators and are an important component of offshore wind power infrastructure.

[0003] In the existing technology, offshore wind tower welding equipment mainly adopts submerged arc welding technology. The welding equipment usually includes a welding operating frame, welding power source and welding system and roller frame. In addition, some equipment adopts double-sided submerged arc welding, which improves efficiency by welding the inner and outer sides at the same time. The internal tower welding device consists of a self-propelled vehicle and a welding robot, which can realize synchronous welding of the inner and outer sides.

[0004] In existing technologies, wind tower welding relies heavily on manual operation, which is not only labor-intensive and consumes a lot of manpower, but also makes it difficult to accurately control the horizontal state of the welding torch, resulting in insufficient flatness and precision of the welded joint. At the same time, existing welding equipment lacks a flexible adjustment mechanism to adapt to wind towers of different diameters, which cannot efficiently meet the needs of diverse welding processes and has a low degree of automation, thus restricting the efficiency and quality improvement of welding operations. Therefore, a marine wind tower welding equipment is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3The present invention provides an embodiment of a welding device for offshore wind towers, comprising a support platform 1. The support platform 1 has an adjustment mechanism 2 and a disassembly mechanism 3 on its top. The adjustment mechanism 2 includes a limiting disc 211, which is a ring-shaped fixed structure that restricts the sliding trajectory of a limiting shaft 216. An arc-shaped groove 212 is formed on the inner wall of the limiting disc 211, providing a guiding sliding path for the limiting shaft 216. A circular plate 213 is rotatably connected to the bottom of the limiting disc 211, providing an installation and rotation carrier for a slider 215. A limiting groove 214 is formed on the inner wall of the circular plate 213, restricting the sliding range of the slider 215. A slider 215 is slidably connected to the inner wall of the limiting groove 214, providing installation support for a welding torch 311. A limiting shaft 216 is fixedly connected to the top of the slider 215, connecting the slider 215 to the arc-shaped groove 212. 12. To achieve linkage guidance, the outer wall of the limiting shaft 216 is slidably connected to the inner wall of the arc groove 212. The outer wall of the limiting disc 211 is fixedly connected to the ring tooth 217. The ring tooth 217 meshes with the gear 218 to transmit power. The outer wall of the ring tooth 217 is meshed with the gear 218. The gear 218 transmits the power of the motor 219 to the ring tooth 217. The support platform 1 is the overall bearing foundation of the equipment. The top of the support platform 1 is fixedly connected to the limiting frame 220. The limiting frame 220 restricts the sliding direction of the support block 223. The inside of the limiting frame 220 is fixedly connected to the electric push rod 221. The electric push rod 221 drives the support block 223 to move up and down. The inner rod of the electric push rod 221 is fixedly connected to the support block 223. The support block 223 receives the power of the electric push rod 221 and supports the circular plate 213. The outer wall of the support block 223 is slidably connected to the inner wall of the limiting frame 220. The top of the support block 223 is fixedly connected to the bottom of the circular plate 213.

[0031] Reference Figure 1 , Figure 3 The adjustment mechanism 2 also includes a support plate 222, which provides fixed support for the motor 219. The outer wall of the support plate 222 is fixedly connected to the outer wall of the limit frame 220. The adjustment mechanism 2 also includes a motor 219, which provides rotational power for the gear 218. The outer wall of the motor 219 is fixedly connected to the inner wall of the support plate 222. The output shaft of the motor 219 is fixedly connected to the bottom of the gear 218. The disassembly mechanism 3 includes a welding gun 311, which provides welding function for welding the wind tower 314. The welding gun 311 is slidably connected to the inner wall of the slider 215.

[0032] Reference Figure 2 , Figure 3The disassembly mechanism 3 also includes a limiting plate 315, which limits the hinge position of the fixing plate 312. The bottom of the limiting plate 315 is fixedly connected to the top of the slider 215. The disassembly mechanism 3 also includes a fixing plate 312, which cooperates with the limiting plate 315 to fix the welding gun 311. The outer wall of the fixing plate 312 is hinged to the outer wall of the limiting plate 315. The bottom of the fixing plate 312 abuts against the top of the slider 215. The disassembly mechanism 3 also includes a torsion block 313, which rotates and abuts against the fixing plate 312 to lock the welding gun 311. The outer wall of the torsion block 313 is rotatably connected to the inner wall of the slider 215. The outer wall of the torsion block 313 abuts against the outer wall of the fixing plate 312. The disassembly mechanism 3 also includes a wind tower 314, which is the target workpiece for welding operations. The outer wall of the wind tower 314 abuts against the outer wall of the welding gun 311.

[0033] Working principle: When welding two wind turbine towers 314, the support platform 1 is first hoisted to a preset position on the outer wall of the wind turbine tower 314 by a crane. Then, the electric actuator 221 inside the limiting frame 220 is activated. The inner rod of the electric actuator 221 synchronously pushes the support block 223 to gradually move upward along the guide structure inside the limiting frame 220. The support block 223 maintains stable sliding under the constraint of the limiting frame 220, ensuring that the circular plate 213 maintains a vertical movement posture throughout the lifting process. This ensures that the welding torch 311 installed on the slider 215 remains horizontal during the welding operation, effectively improving the flatness and accuracy of the weld joint. This is particularly relevant for different diameter gauges. The wind tower 314 can be driven by a starter motor 219. The output shaft of the motor 219 drives the gear 218 to rotate. The gear 218 meshes with the ring tooth 217 on the outer side of the limiting disc 211, thereby driving the limiting disc 211 to rotate. The arc groove 212 on the limiting disc 211 gradually exerts a squeezing force on the limiting shaft 216 during the rotation process, causing the slider 215 connected to the limiting shaft 216 to slide synchronously along the limiting groove 214, gradually approaching the outer wall of the wind tower 314 and adjusting to the optimal welding spacing, thus completing the automated welding operation. This significantly reduces the intensity of manual operation and manpower consumption, while meeting the welding process requirements of wind towers 314 of different specifications.

[0034] When the welding torch 311 needs to be replaced due to wear or process adjustment, the operator only needs to manually twist the toggle block 313 to make the outer contour of the toggle block 313 consistent with the shape of the slot on the fixing plate 312. This will release the limiting and fixing effect of the fixing plate 312 on the welding torch 311. After opening the fixing plate 312, the old welding torch 311 can be taken out from the installation slot on the slider 215 along the sliding direction. Then, the new welding torch 311 can be slid and installed in place along the same slot. Twisting the toggle block 313 in the opposite direction will complete the fixing. This allows for quick and convenient replacement of the welding torch 311, greatly shortening the equipment downtime for replacement and improving the overall welding operation efficiency.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
