Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine tower production, and in particular to a support device for welding in wind turbine tower production. Background Technology

[0002] Wind turbine towers are mostly large cylindrical structures, welded from multiple sections of curved steel plates. During their production, welding at the joints of the steel plates requires a support device to stabilize and fix the tower, while also facilitating its rotation for circumferential welding. Current support devices have limitations in adaptability. For towers of different diameters, it is difficult to flexibly adjust the support position, and for large or small diameter towers, the support may be unstable. The support methods are also relatively simple, with many devices only providing external support. During welding, uneven stress can cause the tower to wobble, potentially affecting welding accuracy. Furthermore, the contact points with the tower are often hard, which can scratch the tower surface and cause excessive friction, making it difficult to rotate and adjust the tower smoothly. Therefore, it is necessary to design a welding support device that is flexible, provides stable support, and protects the tower surface. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support device for welding in the production of wind turbine towers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A support device for welding wind turbine towers includes a base plate, a double-ended screw rotatably connected to the base plate, the double-ended screw threadedly connected to two platforms, the two ends of the double-ended screw having opposite thread designs, a first roller rotatably connected to each of the two platforms, a column fixedly connected to one end and the other end of each of the two platforms, multiple grooves equally spaced on each of the two columns, rods clearance-fitted to each of the two columns, multiple protrusions equally spaced and fixedly connected at the contact points between the rods and the columns, the multiple protrusions respectively fitting and contacting the corresponding grooves, and a second roller between every two rods.

[0005] Preferably, each of the plurality of rods is rotatably connected to a sleeve, each of the plurality of sleeves is inserted with a hexagonal block, and each of the plurality of hexagonal blocks is fixedly connected to a corresponding second roller.

[0006] Preferably, both the first roller and the second roller are fixedly connected with rubber sleeves.

[0007] Preferably, a first motor is fixedly connected to one of the platform bodies, and the first motor is fixedly connected to a corresponding first roller body.

[0008] Preferably, two slide rails are fixedly connected to one end and the other end of the base plate, and the two slide rails are slidably connected to the two platform bodies.

[0009] Preferably, a second motor is fixedly connected to the base plate, and the second motor is fixedly connected to a double-headed screw.

[0010] Preferably, the outer wall of the double-headed screw is fitted with multiple corrugated pipes, and one end of each corrugated pipe is fixedly connected to the base plate or the two platforms.

[0011] The beneficial effects of this utility model are as follows: 1. By coordinating the base plate, platform, double-headed screw, first roller, column, rod, groove, protrusion, and second roller, the double-headed screw drives the two platforms to adjust the distance between them. This allows for flexible adjustment of the distance between the two first rollers, thus adapting to wind turbine towers of different diameters to a certain extent and improving the existing device's insufficient adaptability to support towers of different sizes. Simultaneously, the multiple protrusions on the rod and the multiple grooves on the column allow for adjustment of the rod's placement angle, thereby changing the distance between the second and first rollers. This creates bidirectional support, with the second roller providing support from inside the tower and the first roller from the outside, reducing uneven stress and swaying caused by single external support and improving welding accuracy. This design allows for proper contact between the rollers and the tower surface through adjustment, avoiding surface scratches caused by hard contact. Furthermore, the roller structure facilitates smooth tower rotation, better meeting the welding operation's requirements for support stability, adjustment flexibility, and surface protection. 2. By cooperating with the column, rod, sleeve, hexagonal block, and second roller, the rod is separated from the column, and the sleeve at the other end of the rod is separated from the hexagonal block of the second roller. This allows for quick disassembly of the second roller, preventing it from obstructing the hoisting path when the tower is lifted above the two first rollers. This provides ample operating space for tower placement, reduces the risk of collisions with equipment components during hoisting, and makes the tower placement process smoother and more efficient. It also facilitates flexible assembly and disassembly of the second roller according to actual needs, improving the ease of use of the equipment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figures 1 to 5 A support device for welding wind turbine towers includes a base plate 1, with a double-ended screw 3 rotatably connected to the base plate 1. The double-ended screw 3 is threadedly connected to two platforms 2. The two ends of the double-ended screw 3 have opposite thread designs, which allows the two platforms 2 to move synchronously in opposite directions when the double-ended screw 3 rotates. Each platform 2 is rotatably connected to a first roller 4, the axis of which is aligned with the length direction of the platform 2. The first roller 4 is used to support the bottom outer wall of the wind turbine tower from the outside. One end and the other end of each platform 2 are fixed. The tower is connected to two columns 6, each with multiple grooves 7 equidistantly spaced. Each column 6 is fitted with a rod 5 with a clearance fit. Multiple protrusions 8 are fixedly connected at equal intervals at the contact points between the rod 5 and the column 6. The multiple protrusions 8 are adapted to and in contact with the corresponding grooves 7. The multiple protrusions 8 can be embedded into the grooves 7 of the corresponding column 6 and make tight contact. The angle of the rod 5 is fixed through the concave-convex fit. A second roller 9 is provided between every two rods 5. The second roller 9 is used to support the bottom inner wall of the wind turbine tower from the inside.

[0016] In this embodiment, multiple rods 5 are rotatably connected to sleeves 10, and hexagonal blocks 11 are inserted into each sleeve 10, allowing the second roller 9 to rotate via the contact between the hexagonal blocks 11 and the sleeves 10, and enabling disassembly and assembly. Multiple hexagonal blocks 11 are fixedly connected to their respective second rollers 9. Rubber sleeves 12 are fixedly connected to both first rollers 4 and second rollers 9, and these rubber sleeves 12 are used for tower contact. A platform 2 is fixedly connected to a first motor 13, the model of which is selected according to actual working requirements. The first motor 13 is fixedly connected to its corresponding first roller 4. Two slide rails 16 are fixedly connected to one end and the other end of the base plate 1. The two slide rails 16 are slidably connected to the two platform bodies 2, which can limit the movement direction of the platform bodies 2 and ensure the movement stability of the platform bodies 2. A second motor 14 is fixedly connected to the base plate 1. The model of the second motor 14 is selected according to the actual working requirements. The second motor 14 is fixedly connected to the double-ended screw 3. The outer wall of the double-ended screw 3 is fitted with multiple corrugated pipes 15. One end of the multiple corrugated pipes 15 is fixedly connected to the base plate 1 or the two platform bodies 2 respectively, to prevent dust, welding slag and other debris from entering the thread gap of the double-ended screw 3 and affecting the transmission.

[0017] The working principle of this embodiment is as follows: In use, the second motor 14 is first connected to an external power supply and control device to operate, driving the double-headed screw 3 to adjust the spacing between the two platform bodies 2, flexibly changing the spacing between the two first roller bodies 4 to adapt to the diameter of the wind turbine tower to be welded to a certain extent; then, the rod body 5 is separated from the column body 6, and simultaneously, the sleeve 10 at the other end of the rod body 5 is separated from the hexagonal block 11 of the second roller body 9, quickly disassembling the second roller body 9 to create sufficient space for tower hoisting, avoiding obstruction of the hoisting path, and smoothly hoisting the tower to the top of the two first roller bodies 4; then, according to the tower... The diameter of the cylinder is adjusted by using multiple protrusions 8 on the rod 5 and multiple grooves 7 on the column 6 to adjust the placement angle of the rod 5, thereby changing the distance between the second roller 9 and the first roller 4. The second roller 9 is then reinstalled, so that the first roller 4 provides bidirectional support from the outside and the second roller 9 from the inside. During the adjustment process, it is ensured that the first roller 4 and the second roller 9 maintain appropriate contact with the surface of the tower, which avoids scratching the surface by hard contact and facilitates smooth rotation of the tower with the help of the roller structure. This reduces uneven force and shaking caused by single support, ensuring the stability, accuracy and ease of operation of the welding operation.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
