Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine manufacturing equipment, specifically relating to a welding device for wind turbine manufacturing. Background Technology

[0002] In the field of wind turbine manufacturing, the welding quality of the wind duct plays a crucial role in the performance of the wind turbine.

[0003] Currently, during the manufacturing process of ventilation ducts, the sheet metal generally exhibits varying degrees of springback after being rolled into shape, resulting in increased gaps at the welding points. This not only significantly increases the difficulty of welding operations but also adversely affects the overall welding quality of the ventilation duct.

[0004] To address the gap issue at the weld joint of rolled steel sheets, traditional processes involve manually pressing the sheets to ensure a tight fit. The specific procedure involves first manually pressing the rolled sheet, then performing preliminary welding to fix the ends of the duct, and finally welding the middle gap. However, for large axial flow fans widely used in mining, the duct dimensions are large and the steel sheets are thick. This manual pressing welding method requires multiple operators, significantly increasing labor intensity. Furthermore, the cumbersome process makes the welding time-consuming, resulting in extremely low welding efficiency. This inefficiency not only severely restricts the production progress of fan manufacturing but also increases production costs, impacting the company's economic benefits. Therefore, this paper proposes a welding device for fan manufacturing to solve the aforementioned technical problems. Utility Model Content

[0005] To address the problems of difficult weld joints, cumbersome operations, and reduced welding efficiency in existing technologies for welding wind turbine ducts, this invention provides a welding device for wind turbine manufacturing. This device uses a transport vehicle to place the wind turbine duct over a positioning cylinder, and then uses a lateral force application device to push the duct, completing the weld joint of the duct roll plates. The entire process is mechanical, replacing manual operation, saving time and labor, improving welding accuracy and efficiency, and thus increasing overall welding efficiency. Simultaneously, this device reduces human involvement in high-risk operations, lowers the risk of operator injury, improves production safety, reduces material waste, and saves production costs. It effectively solves the problems of difficult weld joints, cumbersome operations, and reduced welding efficiency in existing technologies for welding wind turbine ducts. The specific technical solution is as follows:

[0006] A welding apparatus for wind turbine manufacturing includes an equipment frame, within which a welding equipment body is disposed. Two support plates are symmetrically fixedly installed on the inner sidewall of the equipment frame. A transfer trolley for carrying a wind duct is slidably installed between the two support plates. A rack plate is fixedly installed on the upper surface of each support plate. A traveling mechanism is installed on the left side of the upper surface of the transfer trolley. The traveling mechanism cooperates with the rack plate to drive the transfer trolley to move. A fixing plate is fixedly installed inside the equipment frame. A positioning cylinder is fixedly installed on the right surface of the fixing plate. Two side plates are symmetrically fixedly installed inside the equipment frame. A lateral force application device is installed on the opposite surface of each of the two side plates.

[0007] In the above technical solution, two adapter seats A and adapter seats B are fixedly installed on the opposite surfaces of the two side plates. The side force application device includes a V-shaped frame and a hydraulic telescopic rod. The end of the V-shaped frame near the side plate is rotatably connected to the corresponding adapter seat A. A force application roller is fixedly installed at the end of the V-shaped frame away from the side plate, and a fixing rod is fixedly installed inside the V-shaped frame. The end of the hydraulic telescopic rod near the side plate is rotatably connected to the corresponding adapter seat B, and the end of the hydraulic telescopic rod away from the side plate is rotatably connected to the fixing rod.

[0008] In the above technical solution, the force-applying roller is a rubber roller.

[0009] In the above technical solution, the front and rear surfaces of the transfer vehicle are provided with sliding grooves, and the sliding grooves are slidably connected to the corresponding support plates. In the above technical solution, the upper surface of the support plates is fixedly installed with rack plates. The walking mechanism includes a dual-output motor and four bearing seats.

[0010] In the above technical solution, four support columns are fixedly installed on the upper surface of the transfer vehicle, and an inverted trapezoidal support plate is fixedly installed between the upper surfaces of the four support columns.

[0011] In the above technical solution, a retaining ring is fixedly installed on the left end of the inverted trapezoidal support plate.

[0012] The welding device for wind turbine manufacturing disclosed in this utility model has the following advantages compared with the prior art:

[0013] I.

[0022] 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.

[0023] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-6 This utility model provides a technical solution:

[0024] A welding device for wind turbine manufacturing includes an equipment frame 1, a welding equipment body 2 disposed inside the equipment frame 1, two support plates 11 symmetrically fixedly installed on the inner side wall of the equipment frame 1, a transfer vehicle 3 for carrying a wind duct slidably installed between the two support plates 11, and a rack plate 111 fixedly installed on the upper surface of each support plate 11. A traveling mechanism 4 is installed on the left side of the upper surface of the transfer vehicle 3. The traveling mechanism 4 cooperates with the rack plate 111 to drive the transfer vehicle 3 to move. A fixing plate 12 is fixedly installed inside the equipment frame 1, a positioning cylinder 5 is fixedly installed on the right surface of the fixing plate 12, and two side plates 13 are symmetrically fixedly installed inside the equipment frame 1. A lateral force application device 6 is installed on the opposite surface of each of the two side plates 13.

[0025] It should be noted that, in combination Figure 3 and Figure 5 As shown, two adapter seats A131 and B132 are fixedly installed on the opposite surfaces of the two side plates 13. The side force application device 6 includes a V-shaped frame 61 and a hydraulic telescopic rod 62. The end of the V-shaped frame 61 near the side plate 13 is rotatably connected to the corresponding adapter seat A131. A force application roller 63 is fixedly installed at the end of the V-shaped frame 61 away from the side plate 13, and a fixing rod 611 is fixedly installed inside the V-shaped frame 61. The end of the hydraulic telescopic rod 62 near the side plate 13 is rotatably connected to the corresponding adapter seat B132, and the end of the hydraulic telescopic rod 62 away from the side plate 13 is rotatably connected to the fixing rod 611.

[0026] The extension and retraction of the hydraulic telescopic rod 62 can drive the V-shaped frame 61 to rotate, thereby driving the force roller 63 to rotate towards or away from the air duct. When the force rollers 63 on both sides are driven by the V-shaped frame 61 to rotate inward at the same time, the connection at the gap of the air duct plate can be completed.

[0027] In practical application, the duct to be welded is placed with the seam facing upwards on the transfer cart 3. Then, the traveling mechanism 4 moves the transfer cart 3 towards the positioning cylinder 5, fitting the duct over the outside of the positioning cylinder 5. Simultaneously, the hydraulic telescopic rods 62 on both sides extend, and the corresponding V-shaped frame 61 drives the force rollers 63 on both sides to apply pressure to the duct, thus completing the seam connection. After connection, keeping the force rollers 63 in place, welding is performed using the welding equipment body 2. Then, the hydraulic telescopic rods 62 retract, resetting the V-shaped frame 61 and force rollers 63. Finally, the traveling mechanism 4 moves the transfer cart 3 and the duct out of the welding area. Compared to existing technologies, the entire seam connection process before welding the duct is completed mechanically, replacing manual operation. This saves time and labor, improves connection accuracy and efficiency, and ultimately increases welding efficiency. Simultaneously, this device reduces human involvement in high-risk operations, lowers the risk of operator injury, improves production safety, reduces material waste, and saves production costs.

[0028] To reduce the damage to the air duct caused by the pressure roller 63 during the pressure application process, the pressure roller 63 is set as a rubber roller. By utilizing the elastic properties of the rubber roller, the pressure application effect is ensured while reducing damage to the surface of the air duct.

[0029] Combination Figure 1 and Figure 2 As shown, the front and rear surfaces of the transfer vehicle 3 are provided with sliding grooves 34, which are slidably connected to the corresponding support plates 11. The upper surface of the support plates 11 is fixedly mounted with rack plates 111. The traveling mechanism 4 includes a dual-output motor 41 and four bearing seats 42. The dual-output motor 41 and the bearing seats 42 are fixedly mounted on the left side of the upper surface of the transfer vehicle 3. A rotating shaft 43 is rotatably mounted between two corresponding bearing seats 42. The inner ends of the two rotating shafts 43 are fixedly connected to the output ends of the corresponding side of the dual-output motor 41, and the outer ends of the two rotating shafts 43 are fitted with gears 44. The gears 44 are meshed with the corresponding rack plates 111. The dual-output motor 41 is a forward and reverse motor. After it is started, it can drive the transfer vehicle 3 to move through the cooperation of the gears 44 and the rack plates 111.

[0030] Specifically, such as Figure 2 As shown, four support columns 31 are fixedly installed on the upper surface of the transfer vehicle 3, and an inverted trapezoidal support plate 32 is fixedly installed between the upper surfaces of the four support columns 31. The inverted trapezoidal support plate 32 can be used to stably place the air duct to be welded on the transfer vehicle 3.

[0031] Finally, to facilitate the easy disassembly of the air duct from the positioning cylinder 5 after welding, such as Figure 2As shown, a retaining ring 33 is fixedly installed at the left end of the inverted trapezoidal support plate 32. It is important to note that after installation, the center of the retaining ring 33, the axis of the positioning cylinder 5, and the axis of the air duct to be welded are all in the same horizontal position. Furthermore, the inner diameter of the retaining ring 33 is the same as the outer diameter of the positioning cylinder 5. This ensures that the retaining ring 33 can fit onto the outer surface of the positioning cylinder 5 while simultaneously pushing the air duct away. After welding, the air duct, fitted onto the outer surface of the positioning cylinder 5, experiences friction. During unloading, the traveling mechanism 4 drives the transfer vehicle 3 to move horizontally to the right, causing the retaining ring 33 to move to the right and push the air duct, allowing it to overcome the friction with the positioning cylinder 5 and detach from it, thus completing the unloading process. This structural design effectively improves the convenience of unloading the air duct after welding.
