Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to an adjustable grating steel structure welding tool. Background Technology

[0002] A bar screen typically consists of a set of parallel bars, placed obliquely at the inlet of a pump station's sump. During welding, the screen is placed horizontally on a workbench, and welding tools are used to weld the multiple parallel bars together. Due to the large area of ​​the screen, the operator needs to constantly adjust its position during welding. After one side of the screen is finished, it needs to be flipped over and welded again, which affects the efficiency of the welding process. Adjusting the screen's position can also cause slight displacement of the material being welded, resulting in the bars tilting after welding, thus affecting the quality and aesthetics of the screen.

[0017] 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.

[0018] Reference Figures 1-3An adjustable grating steel structure welding tool includes a base 1 equipped with casters, a support cylinder 2 fixedly mounted on the base 1, and a hydraulic cylinder 3 for adjusting the height of the grating fixedly mounted inside the support cylinder 2. A support rod is fixedly connected to the output end of the hydraulic cylinder 3, and a support plate 4 is fixedly connected to the output end of the support rod. The support plate 4 and the support rod extend to the upper end outside the support cylinder 2. A guide rod connected to the support plate 4 is slidably sleeved inside the support cylinder 2. The support cylinder 2 guides the support rod, and the guide rod guides the support plate 4. The height of the grating can be adjusted by extending and retracting the output end of the hydraulic cylinder 3, making it more convenient for the operator to weld the grating.

[0019] A frame 5 is fixedly installed on the support plate 4, and a clamping structure for clamping the grille is fixedly installed on the frame 5, according to the instruction manual. Figure 1 As shown, by placing the grille inside the frame 5, the grille is in a vertical position, and because of the vertical placement of the grille, it does not need to be manually flipped during welding.

[0020] The clamp structure includes a sleeve 6 fixedly installed on the frame 5, and a movable rod 7 is slidably sleeved inside the sleeve 6. A limiting plate 10 extending to the grid is fixedly installed on the movable rod 7. A spring 8 is welded between the sleeve 6 and the movable rod 7. The sleeve 6 guides the movable rod 7 and the limiting frame 9, so that the movable rod 7 can drive the limiting plate 10 to move smoothly when it moves.

[0021] The sleeve 6 is horizontally positioned on both sides of the frame 5. The limiting plate 10 and the moving rod 7 extend to one side of the frame 5. The limiting frame 9 has an L-shaped structure. The spring 8 is horizontally welded. The limiting frame 9, which is connected to the moving rod 7, is slidably mounted on the sleeve 6. The limiting frame 9 has a T-shaped structure. The spring 8 resets the moving rod 7. When the limiting frame 9 is unloaded, the spring 8 can drive the moving rod 7, the limiting frame 9, and the limiting plate 10 back to their initial positions. After the grille is placed inside the frame 5, the limiting plate 10 can clamp the bottom of the grille from both sides.

[0022] A clamp 15 for pressing the sides of the grille is connected to the frame 5 via a movable component.

[0023] The moving part includes a motor 11 fixedly mounted on the frame 5, and a bidirectional lead screw 12 is fixedly connected to the output end of the motor 11. Two matching nuts 13 are slidably sleeved on the bidirectional lead screw 12. A support rod 14 connected to the nuts 13 is slidably sleeved inside the frame 5. A clamping plate 15 is provided on the support rod 14. After the motor 11 is powered on, it drives the bidirectional lead screw 12 to rotate. This technical solution is existing technology and will not be elaborated on here.

[0024] The bidirectional lead screw 12 is horizontally set, and the clamping plate 15 and the support rod 14 extend to the upper end of the frame 5. The clamping plate 15 has a concave structure, and the frame 5 has an elongated hole for guiding the support rod 14. The elongated hole guides the support rod 14 and limits the movement direction of the nut 13. After the motor 11 is powered on, the two clamping plates 15 clamp the grid from both sides. This not only allows the clamping plates 15 to limit the grid of different specifications, but also ensures the stability of the grid during welding.

[0025] This utility model uses self-locking moving wheels to move the base 1 to a designated processing point; the two limiting frames 9 are pulled out and the grille is placed inside the frame 5. The traction on the grille is released, and the moving rod 7 slides inside the sleeve 6 under the action of the spring 8, so that the moving rod 7 drives the limiting plate 10 to clamp the lower end of the grille from both sides; the output end of the motor 11 drives the bidirectional lead screw 12 to rotate, and the bidirectional lead screw 12 drives the two nuts 13 to move in opposite directions; when the two nuts 13 move in opposite directions, the support rod 14 slides in the elongated hole, and the support rod 14 drives the clamping plate 15 to press the two sides of the grille from both sides. The operator performs welding operations on the grille using a welding machine; the extension and retraction of the output end of the hydraulic cylinder 3 drives the support rod to slide inside the support cylinder 2, and the support rod drives the support plate 4 and the frame 5 to move, so that the frame 5 can adjust the height of the grille.

[0026] 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.
