Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a welding device for hanging wires on the structural beams of power transmission line substations. Background Technology

[0002] There are two types of hanging points welded on the structural beams of power transmission line substations: radial hanging points and axial hanging points. The weld seam of the axial hanging point is straight, and the weld quality is easy to control. However, the weld seam of the radial hanging point is circular, which is more difficult to weld. When performing tack welding, workers usually hold the hanging plate and attach it to the structural beam by hand. The assembly angle between the hanging plate and the structural beam is not easy to control, and it is easy to cause skewing, which is not conducive to the normal use of the hanging point. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, a welding device for hanging wires on a substation frame beam of a power transmission line includes a welding platform 101. The welding platform 101 is provided with an adjustable support structure that supports the frame beam 102. The welding platform 101 is connected to a correction plate 401 that plays an angle positioning role for the hanging wire plate 103 through the adjustment structure. The correction plate 401 is provided with an auxiliary correction component.

[0024] In this embodiment, an adjustable support structure provides horizontal support for frame beams 102 of different diameters. By adjusting the structure, the correction plate 401 is positioned near the frame beam 102. The worker holds the hanging plate 103, and with the auxiliary correction effect of the correction plate 401, the hanging plate 103 is perpendicular to the frame beam 102. Then, the frame beam 102 and the hanging plate 103 are connected together by tack welding, which facilitates control of the assembly angle between the frame beam 102 and the hanging plate 103.

[0025] In one embodiment, such as Figures 1-2As shown, the adjustable support structure includes two second riser frames 205 connected to the welding platform 101. Second rollers 206 are rotatably connected to the second riser frames 205, and the rotation axes of the two second rollers 206 are collinear. A drive assembly is provided on the second riser frames 205. The welding platform 101 is slidably connected to a sliding plate 202 via a shifting assembly. Two first riser frames 203 are provided on the sliding plate 202, and first rollers 204 are rotatably connected to the first riser frames 203. The positions of the first rollers 204 correspond one-to-one with the positions of the second rollers 206. The rotation axes of 204 are collinear. A telescopic rod 210 is provided on the welding platform 101. The output end of the telescopic rod 210 is connected to a sliding plate 202. The first roller 204 and the second roller 206 cooperate to support the frame beam 102. The extension and retraction of the telescopic rod 210 improves the stability when supporting frame beams 102 of different diameters. The drive assembly includes a drive motor 207 connected to the second extension frame 205. The output end of the drive motor 207 is coaxially connected to the second roller 206. The drive motor 207 drives the second roller 206 to rotate. The supported frame beam 102 rotates, facilitating worker handling of the welding position. The displacement component includes a first slide groove 201 disposed on both sides of the welding platform 101. A sliding plate 202 is slidably disposed within the first slide groove 201. A sliding support module is provided between the sliding plate 202 and the welding platform 101. The first slide groove 201, located on the side of the welding platform 101, effectively prevents impurities such as welding slag and iron filings from falling into it and affecting the sliding of the sliding plate 202. The sliding support module includes two... The slider 209 is positioned corresponding to the first heightening frame 203. Two parallel guide rails 208 are provided on the welding platform 101, with the positions of the guide rails 208 corresponding to the slider 209. The slider 209 slides in contact with the guide rails 208. To reduce sliding friction, the sliding plate 202 is a cantilever structure, that is, both ends are slidably set in the first slide groove 201, and the middle area is suspended. In order to reduce the deformation of the sliding plate 202 when supporting the frame beam 102, the guide rails 208 cooperate with the slider 209 to support the sliding plate 202 and reduce the deformation of the sliding plate 202.

[0026] In one embodiment, such as Figure 1As shown, the adjustment structure includes a second slide groove 301 disposed on the welding platform 101, a height adjustment rod 302 slidably disposed within the second slide groove 301, a height adjustment groove 303 disposed on the height adjustment rod 302, a lifting plate 304 slidably disposed within the height adjustment groove 303, a first locking bolt 305 threadedly connected to the lifting plate 304 corresponding to the position of the height adjustment groove 303, a third slide groove 306 disposed on the lifting plate 304, an extension plate 307 slidably disposed within the third slide groove 306, and an extension plate 307 corresponding to the position of the third slide groove 304. The groove 306 is threaded with a second locking bolt 308. The extension plate 307 is connected to a correction plate 401. The extension plate 307 slides in the third slide groove 306 to adjust the horizontal distance between the correction plate 401 and the frame beam 102. The lifting plate 304 slides in the height adjustment groove 303 to adjust the vertical distance between the correction plate 401 and the frame beam 102. The height adjustment rod 302 slides in the second slide groove 301 to adjust the corresponding position of the correction plate 401 on the frame beam 102.

[0027] In one embodiment, such as Figures 3-4 As shown, the correction plate 401 is magnetic. The auxiliary correction assembly includes four cavities 402 disposed on the correction plate 401. A circular hole 404 is provided on the correction plate 401 at a position corresponding to the cavity 402. The diameter of the circular hole 404 is smaller than the inner diameter of the cavity 402. A ball bearing 403 rolls inside the cavity 402. A cover 405 is connected to the correction plate 401 at a position corresponding to the cavity 402. The cover 405 contacts the ball bearing 403. The diameter of the ball bearing 403 matches the inner diameter of the cavity 402. The four cavities 402... With identical specifications, the four round holes 404 are of the same size. When the worker holds the hanging plate 103, the correction plate 401 magnetically attracts the hanging plate 103. The hanging plate 103 is in close contact with the ball bearings 403 protruding from the round holes 404 on the correction plate 401, making the hanging plate 103 parallel to the correction plate 401. That is, the hanging plate 103 remains perpendicular to the frame beam 102. At the same time, the ball bearings 403 themselves roll within the cavity 402, reducing the resistance when the worker adjusts the position of the hanging plate 103.

[0028] In one embodiment, such as Figure 4 As shown, the ball bearing 403 is made of aluminum alloy to prevent the ball bearing 403 from being interfered with by the magnetism of the correction plate 401.

[0029] The above embodiment discloses a welding device for the hanging points of a transmission line substation frame beam. The first roller 204 and the second roller 206 cooperate to support the frame beam 102. The extension and retraction of the telescopic rod 210 improves the stability when supporting frame beams 102 of different diameters. A drive motor 207 drives the second roller 206 to rotate, which in turn drives the supported frame beam 102 to rotate, facilitating worker handling of the welding position. The horizontal distance between the correction plate 401 and the frame beam 102 is adjusted by the sliding of the extension plate 307 within the third slide groove 306. The vertical distance between the correction plate 401 and the frame beam 102 is adjusted by the sliding of the lifting plate 304 within the height adjustment groove 303. The distance is adjusted by sliding the height adjustment rod 302 within the second slide groove 301, thereby adjusting the corresponding position of the correction plate 401 on the frame beam 102. This positions the correction plate 401 near the frame beam 102. The worker holds the hanging plate 103, and under the magnetic action of the correction plate 401, the correction plate 401 attracts the hanging plate 103. The hanging plate 103 is in close contact with the ball bearing 403 protruding from the round hole 404 on the correction plate 401, making the hanging plate 103 parallel to the correction plate 401. That is, the hanging plate 103 remains perpendicular to the frame beam 102. At the same time, the ball bearing 403 rolls within the cavity 402, reducing the resistance when the worker adjusts the position of the hanging plate 103, thus facilitating the control of the assembly angle between the frame beam 102 and the hanging plate 103.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
