[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind wheel, a generator, a stabiliser (tail), a tower and other components, among which the generator is the most core component.

[0003] The generator is mainly composed of a stator, a rotor and other components. Generally speaking, the stator is composed of a circular ring composed of 4 silicon steel sheets stacked together. Since the wind turbine itself is very large, the silicon steel sheets need to be welded to form a closed ring structure.

[0004] In the prior art, various transport devices are needed to transport silicon steel sheets in a workshop, and then several silicon steel sheets are combined by adding some supporting devices and cooperating with the transport devices, and then they are welded manually. Firstly, the transport and combination process of the silicon steel sheets is very slow. Secondly, when welding, because there are four welding positions, the welding workers need to move positions to perform welding. The above two aspects are the main reasons for the low efficiency of the existing welding work. Therefore, a high-efficiency welding device for a wind turbine stator is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a high-efficiency welding device for a wind turbine stator provided by an embodiment of the present invention includes a base box 1 with an open top structure, and also includes:

[0032] A transverse conveying assembly 2 is arranged in the base box 1, and the transverse conveying assembly 2 includes a rolling drag chain structure 201 arranged on both sides of the base box 1, and claws 202 for carrying silicon steel sheets 6 are fixedly connected to the rolling drag chain structure 201 at intervals, and the claws 202 limit the silicon steel sheets 6 along both sides of the length direction of the base box 1. A transversely arranged bearing platform 203 is fixedly connected in the base box 1. When the rolling drag chain structure 201 is running, the rolling drag chain structure 201 slides horizontally on the bearing platform 203;

[0033] A guide assembly 3, the guide assembly 3 is located in the middle of the base box 1, and the guide assembly 3 is composed of an arc-shaped tube body 301 disposed on both sides of the top of the base box 1, and the arc-shaped tube body 301 itself is arranged in the vertical direction, and the arc-shaped tube body 301 and the silicon steel sheet 6 have the same curvature radius, and the central angle corresponding to the arc-shaped tube body 301 is greater than 90°. When the silicon steel sheet 6 is located in the arc-shaped tube body 301, the surface of the silicon steel sheet 6 fits with the inner wall of the arc-shaped tube body 301, and a first drive assembly 8 is arranged on the arc-shaped tube body 301. When the silicon steel sheet 6 is located in the arc-shaped tube body 301, the first drive assembly 8 is used to adjust the position of the silicon steel sheet 6 in the arc-shaped tube body 301;

[0034] The second driving assembly 4 is located on the carrying platform 203 and corresponds to the positions of the arc-shaped tube bodies 301 on both sides. When the silicon steel sheet 6 on the claw 202 moves to the top of the second driving assembly 4, the second driving assembly 4 is used to push the silicon steel sheet 6 on the claw 202 into the arc-shaped tube body 301 on either side;

[0035] The welding platform 5 is located on one side of the guide assembly 3 and is arranged close to the loading end of the transverse conveying assembly 2. The arc tube bodies 301 on both sides are used for welding. When a plurality of silicon steel sheets 6 are combined into a closed circular ring 13, the first drive assembly 8 and the second drive assembly 4 are used to drive the combined silicon steel sheets 6 to rotate.

[0036] In one embodiment of the present invention, when the device is in use, although the welding process is still the same as the prior art, the preparation work of the silicon steel sheet 6 of the stator is efficiently optimized, and the silicon steel sheet 6 can be transferred by the transverse conveying component 2. When the silicon steel sheet 6 moves to the position corresponding to the arc tube body 301, the silicon steel sheet 6 on the claw 202 can be transferred to the arc tube body 301 through the cooperation of the first driving component 8 and the second driving component 4. The transverse conveying component 2 continuously replenishes the silicon steel sheet 6, and the silicon steel sheet 6 can automatically complete four silicon steel sheets 6 during the rotation process. The work of the circular ring 13, when welding the silicon steel sheets 6, through the cooperation of the first drive component 8, the second drive component 4, the claws 202 and the arc-shaped tube bodies 301 on both sides, not only can the circular ring 13 composed of the silicon steel sheets 6 be limited, but the entire circular ring 13 can also be driven to rotate, so that the welding worker can complete the welding work of four positions at one position on the welding platform 5, thereby greatly improving the welding efficiency. In summary, the present invention can effectively connect the transfer, assembly and welding during stator welding, thereby greatly improving the overall welding efficiency.

[0037] In an example of the present invention, it should be noted that the spacing at the bottom of the arc-shaped tube body 301 on both sides needs to be greater than the spacing at the top, firstly, it can avoid interference with the silicon steel sheet 6 moving laterally, and at the same time, it can ensure that the silicon steel sheet 6 will not fall off when it rotates to the top, and it is also necessary to expose part of the silicon steel sheet 6 at the top, so that welding can be performed at this position. The welding platform 5 is the same as the prior art and is composed of a welded steel structure, but the welding platform 5 of the present invention needs to extend a length to the inside of the arc-shaped tube body 301 so that the welding of the other side of the silicon steel sheet 6 can be completed on the welding platform 5, such as Figure 1 As shown, both sides of the base box 1 are fixedly connected with guide folding plates 7, and the guide folding plates 7 are arranged near the feeding end of the transverse conveying component 2. The guide folding plates 7 are used to limit the conveyed silicon steel sheets 6, so that the silicon steel sheets 6 can be translated in a symmetrical state on the transverse conveying component 2. In the actual working process, the silicon steel sheets 6 will be moved to the specified position and then transferred to the arc tube body 301. When the three silicon steel sheets 6 are transferred, their reserved positions are limited, and the existence of the guide folding plates 7 can limit the posture of the transferred silicon steel sheets 6, so that they can dock with the three silicon steel sheets 6 to form a closed circular ring 13. At the same time, the position of the conveyed silicon steel sheets 6 is determined, and the distance driven by the first drive component 8 and the second drive component 4 to move the silicon steel sheets 6 can also be more accurate, such as Figure 3As shown, the claw 202 includes a mounting base 2021 fixedly set on the rolling drag chain structure 201, and a U-shaped mounting base 2022 is fixedly connected to the mounting base 2021 and is tilted toward the base box 1. The U-shaped mounting base 2022 on both sides of the supporting platform 203 is in a symmetrical state. Due to the existence of the U-shaped mounting base 2022, not only can the transverse conveying component 2 convey the silicon steel sheet 6, but also it will not affect the second driving component 4 to transfer the silicon steel sheet 6 to the arc tube body 301.

[0038] like Figure 3 , Figure 4 and Figure 6 As shown, as a preferred embodiment of the present invention, the arc tube body 301 includes an arc baffle 3011 fixedly arranged on the base box body 1, the arc baffle 3011 is located on the inner side of the arc tube body 301, and an arc guide rail 3012 is arranged on the outer side of the arc baffle 3011. The arc guide rail 3012 has an open structure facing the arc baffle 3011. When the silicon steel sheet 6 is located in the arc tube body 301, the surface of the silicon steel sheet 6 contacts the inner wall of the arc guide rail 3012, and the inner surface of the silicon steel sheet 6 contacts the surface of the arc baffle 3011, and the first driving component 8 is arranged on the arc guide rail 3012.

[0039] In one case of this embodiment, if Figure 7 As shown, both sides of the top of the base box 1 are fixedly connected with spaced brackets 9, and the top of the bracket 9 near the feeding end of the horizontal conveying component 2 is fixedly connected with a horizontally arranged extension frame 10, the length of the extension frame 10 is greater than the overall width of the arc guide rail 3012, and the other end of the extension frame 10 is fixedly connected to the arc baffle 3011, and the first driving component 8 includes a first power box 801 fixedly set on the arc guide rail 3012, the interior of the first power box 801 is connected to the interior of the arc guide rail 3012, and the first power box 801 is provided with a first driving member 802 and two driving wheels 803 spaced along the vertical direction. The first driving member 802 is used to drive the two driving wheels 803 to rotate synchronously. When the silicon steel sheet 6 is located in the arc When the silicon steel sheet 6 is in the arc guide rail 3012, the driving wheel 803 contacts the surface of the silicon steel sheet 6. When the silicon steel sheet 6 enters the arc guide rail 3012 through the second driving component 4, the second driving component 4 will eventually separate from the silicon steel sheet 6. Therefore, it is necessary to set the first driving component 8 on the arc guide rail 3012. After the silicon steel sheet 6 enters the arc guide rail 3012, it will contact the driving wheel 803. After the first driving component 802 drives the driving wheel 803 to rotate, the silicon steel sheet 6 can be lifted upward in the arc guide rail 3012. Due to the restrictions on the shape and size of the arc baffle 3011 and the arc guide rail 3012, the position of the silicon steel sheet 6 can be determined, thereby ensuring the accuracy of the silicon steel sheet 6 docking, and at the same time, the circular ring 13 composed of the silicon steel sheets 6 will meet the requirements, such as Figure 8As shown, the second driving assembly 4 includes a second power box 401 fixedly connected to the supporting platform 203, and the output end of the second power box 401 is two drive rollers 402 spaced apart and located at the top thereof, and the drive rollers 402 themselves are perpendicular to the moving direction of the silicon steel sheet 6. The first driving member 802 can be in the form of a motor, and the second power box 401 can have a structure similar to that of the first power box 801, or can be in the form of a motor driving the drive rollers 402 to rotate. In the prior art, the driving method of the drive wheel 803 and the drive roller 402 is very conventional, so it will not be described in detail.

[0040] like Figure 7 As shown, to supplement the above embodiment, the tops of all the brackets 9 are fixedly connected with a transversely arranged slide 11, and both sides of the first power box 801 are provided with a moving structure 12 that cooperates with the slide 11. The first driving member 802 is also used to drive the moving structure 12 to move in the slide 11, so that the corresponding arc guide rail 3012 moves laterally, and the first driving member 802 can independently drive the moving structure 12 and the driving wheel 803 to operate.

[0041] In one case of the present embodiment, although the rotation welding of the silicon steel sheet 6 can be completed by the cooperation of the first driving assembly 8 and the second driving assembly 4, when the welding is completed, the silicon steel sheet 6 forms a closed circular ring 13, and the conveying work of the circular ring 13 is problematic, and the lowering arc guide rail 3012 and the arc baffle 3011 are set as a detachable structure, which means that the structure needs to be disassembled before the circular ring 13 can continue to be conveyed. As can be seen from the above, the arc baffle 3011 and the arc The arc guide rail 3012 is detachable. After welding is completed, the first power box 801 moves the arc guide rail 3012 to both sides through the cooperation of the mobile structure 12 and the slideway 11. At this time, the circular ring 13 composed of the silicon steel sheet 6 will be completely exposed, and the welding platform 5 and the extension frame 10 are close to the feeding end of the horizontal conveying component 2. Both will not affect the continued transfer of the circular ring 13. In addition, no matter how the circular ring 13 rotates during welding, the bottom of the circular ring 13 is located on the claw 202, which means that it will appear as follows Figure 1 As shown in the situation, after welding is completed, the claw 202 will be responsible for transferring the ring 13. The moving structure 12 can be in the form of a roller and a slide 11. The above structure can realize the effective connection of loading, assembly, welding and unloading of the entire device. During the entire welding process, pieces of silicon steel sheets 6 are transferred to the designated position and assembled into a ring 13. Then the welded ring 13 is transported through the lateral conveying assembly 2. The length of the slide 11 is greater than the width of the arc guide rail 3012, which can ensure that the arc guide rail 3012 is completely separated from the silicon steel sheet 6, thereby not affecting the lateral movement of the ring 13.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
