Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, and in particular to a square pile welding device. Background Technology
[0002] Welding of precast square piles is a crucial step in building construction, determining the connection strength and overall performance of the pile column. Traditional square pile welding relies heavily on manual labor, requiring welders to hold a welding torch and weld along the joint of the pile. This method is not only labor-intensive, but the welding quality is also susceptible to variations in welder skill level and working environment, making it difficult to guarantee consistency and stability. Furthermore, because square piles are typically large and heavy, welders need to constantly move and adjust their position during operation, increasing the difficulty and potentially leading to welding defects such as uneven welds, slag inclusions, and porosity, thus affecting the overall quality of the square pile.

[0033] Please see Figures 1 to 2 This application provides a square pile welding device, including a fixed frame 1, a movable part 2, a welding torch 3, and a welding machine body 4. The fixed frame 1 is fixedly mounted around the square pile 5 to be welded; the movable part 2 is mounted on the fixed frame 1 and moves around the square pile 5; the welding torch 3 is mounted on the movable part 2; and the welding machine body 4 is electrically connected to the welding torch 3. The purpose of this invention is to install the movable part 2 onto the square pile 5 to be welded using the fixed frame 1. During welding, the welding machine body 4 is energized, and the welding torch 3 begins welding the square pile 5. At this time, the movable part 2 begins to move at a uniform speed around the square pile 5. Because the welding torch 3 is mounted on the movable part 2, it can automatically weld the mating position of the square pile 5. The welding process is automatic, requiring no manual operation of the welding torch 3, thus ensuring welding quality.
[0034] In one embodiment, the fixing frame 1 includes a square frame 11 and two pairs of locking and positioning parts 12. The square frame 11 is arranged around the outside of the welding area 51 of the square pile 5, and the inner corner of the square frame 11 is smoothly transitioned by an arc. The two pairs of locking and positioning parts 12 are symmetrically arranged on two opposite corners of the square frame 11. Each locking and positioning part 12 includes a threaded rod 121, a locking nut 122, a U-shaped rod 123, and a right-angle locking block 124. The threaded rod 121 is fixed to the corner of the square frame 11, and the included angle between the threaded rod 121 and the side of the square frame 11 is 45°. The U-shaped rod 123 is slidably sleeved on the threaded rod 121, and the locking nut 122 is threadedly engaged with the threaded rod 121. The right-angle locking block 124 is fixed to the end of the U-shaped rod 123, and the right-angle groove of the right-angle locking block 124 fits against the right-angle side of the square pile 5.
[0035] After the first square pile 5 is lowered to a certain height, the square frame 11 is first placed on top of the first square pile 5. Then, the pile driver is used to align the second square pile 5 with the top of the first square pile 5, and the two pairs of locking and positioning parts 12 are fixed to the two opposite corners of the square pile 5 by tightening the locking nut 122. Then, the fixing frame 1 is installed on the square pile 5. After welding is completed, the locking nut 122 is loosened, so that the fixing frame 1 is released from the square pile 5. The pile driver continues to press the second square pile 5 down to the predetermined depth. After the pile is completed, the fixing frame 1 is taken out from the top of the second square pile 5. (If it is necessary to continue the pile driving, the fixing frame 1 can be moved and fixed to the docking area (welding area 51) of the second square pile 5 and the third square pile 5, so that the subsequent square piles 5 can be welded.)
[0036] Furthermore, by adjusting the locking nut 122, the distance between the two pairs of locking positioning parts 12 can be adjusted, thereby allowing the fixing frame 1 to be fixed to square piles 5 of different sizes, enabling the square pile 5 welding equipment of this application to weld square piles 5 of different sizes. Moreover, since the right-angle locking block 124 in the locking positioning part 12 of the fixing frame 1 fits onto the edge of the square pile 5, the two pairs of locking positioning parts 12 can be used to position the upper and lower square piles 5, ensuring alignment between the upper and lower square piles 5 before welding and guaranteeing the performance of the welded square pile 5.
[0037] In one embodiment, the moving part 2 includes a power unit 25, a moving platform 22, a rack structure 23, a wheel axle, and a first slide groove 21. The first slide groove 21 is disposed on the square frame 11, and the shortest distance between each point of the first slide groove 21 and the welding position of the square pile 5 is the same. The moving platform 22 is slidably fitted onto the first slide groove 21. The rack structure 23 is disposed on the inner side of the square frame 11. A gear shaft 24 is rotatably disposed on the moving platform 22, and the gear portion of the gear shaft 24 meshes with the rack structure 23. The power unit 25 is disposed on the moving platform 22, and the power output shaft of the power unit 25 is connected to the gear shaft 24. The welding torch 3 is mounted on the moving platform 22.
[0038] During welding, the power unit 25 (which may be a motor) starts to rotate, which in turn causes the wheel axle connected to it to rotate, thereby driving the moving platform 22 to move around the square pile 5, which in turn causes the welding torch 3 fixed on the pancreatic islet functional platform to move around the bag welding area, thereby realizing automatic welding of the square pile 5.
[0039] In one embodiment, the moving part 2 further includes an adjusting seat 26. The moving platform 22 is provided with a second sliding groove facing the square pile 5. The adjusting seat 26 is slidably engaged with the second sliding groove. The adjusting seat 26 is provided with a locking screw structure. The welding torch 3 is mounted on the adjusting seat 26. When it is necessary to adjust the distance between the welding torch 3 and the square pile 5, simply loosen the locking screw structure on the adjusting seat 26 first, then adjust the position of the adjusting seat 26 along the second sliding groove until the distance between the welding torch 3 and the square pile 5 reaches the predetermined position, and then tighten the locking screw structure to lock the adjusting seat 26 and fix the welding torch 3 to the moving platform 22.
[0040] In one embodiment, the moving part 2 further includes an adjusting seat 26, an adjusting cylinder, and a distance sensor. The moving platform 22 is provided with a second sliding groove facing the square pile 5. The adjusting seat 26 is slidably fitted onto the second sliding groove. The adjusting cylinder is installed on the moving platform 22, and the telescopic end of the adjusting cylinder is connected to the adjusting seat 26. The distance sensor is installed on the moving platform 22 and is electrically connected to the adjusting cylinder. The distance sensor monitors the distance between itself and the welding point.
[0041] During welding, the distance sensor monitors the distance between itself and the welding point in real time. Since both the welding torch 3 and the distance sensor are mounted on the moving platform 22, the distance between the welding torch 3 and the welding point can be inferred from the distance between the distance sensor and the welding point. Then, the distance sensor controls the extension and retraction of the adjusting cylinder based on the monitored distance parameters. By controlling the extension and retraction of the adjusting cylinder, the position of the welding torch 3 is adjusted to ensure that the distance between the welding torch 3 and the square pile 5 is within a fixed range, thus ensuring the welding quality.
[0042] Optionally, the distance sensor can be positioned close to the welding torch 3.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
