[0024] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1 - Figure 9The welding device for steel structures shown includes a main body 1. Two side frames 2 are symmetrically mounted at both ends of the top of the main body 1. A collection frame 3 is fixedly mounted on the adjacent surfaces of the two side frames 2. Steel plates are stacked inside the collection frame 3. A pushing mechanism 6 is movably mounted in the inner cavity of the side frame 2, and the pushing mechanism 6 is located below the collection frame 3. An upward moving block 18 is movably mounted between the two side frames 2. A first cylinder 19 is installed inside the main body 1. The output end of the first cylinder 19 is connected to the bottom of the upward moving block 18. The first cylinder 19 can drive the upward moving block 18. The moving block 18 moves upward to facilitate the removal of the welded steel plate. The upper moving block 18 is equipped with a second linkage mechanism 28 on both sides, and the pushing mechanism 6 is equipped with a first linkage mechanism 12 on both sides. The second linkage mechanism 28 cooperates with the first linkage mechanism 12. By setting the first linkage mechanism 12 and the second linkage mechanism 28, the two steel plates can be quickly aligned, improving the welding efficiency of the steel plates. At the same time, the removal of the welded steel plate is quick and convenient, shortening the working time, reducing the workload of manual operation, and improving the safety of manual operation.

[0027] A first sliding groove 4 is installed at the middle of the inner wall of the side frame 2 cavity, and a second sliding groove 5 is installed at the bottom of the inner wall of the side frame 2 cavity. The first sliding groove 4 and the second sliding groove 5 have a limiting and guiding function for the mechanism, making the device more stable during operation. The pushing mechanism 6 includes a pushing plate 7, and a support plate 8 is provided at the end of the pushing plate 7. Two sliding columns 9 are installed on the side of the pushing plate 7. Both sliding columns 9 are slidably installed in the first sliding groove 4. With the cooperation of the first sliding groove 4 and the sliding columns 9, the pushing plate 7 can drive the support plate 8 to slide in the side frame 2 cavity, thereby realizing the pushing operation of the steel plate.

[0028] The tray 8 is located directly below the collection frame 3, and the distance between the tray 8 and the collection frame 3 is the same as the thickness of the steel plate. The width of the tray 8 is shorter than the width of the collection frame 3. A limiting edge 33 is installed on the surface of the tray 8. Due to the weight of the steel plate itself, the steel plate at the bottom of the collection frame 3 will fall onto the surface of the tray 8. When the push plate 7 can move the tray 8 towards the center of the main body seat 1, the end faces of the two steel plates will stick together, which is convenient for subsequent welding operations. At this time, the top of the push plate 7 will seal the opening at the bottom of the collection frame 3 to prevent the steel plate inside the collection frame 3 from falling further.

[0029] The first linkage mechanism 12 includes a connecting rod 13. A positioning shaft 15 is fixedly installed on the bottom surface of the connecting rod 13. The positioning shaft 15 is rotatably connected to the inner wall of the side frame 2. A slot 14 is opened on the top surface of the connecting rod 13. The slot 14 is sleeved on the surface of the sliding column 9 away from the support plate 8. A protruding strip 16 is installed at the bottom end of the connecting rod 13. A contact plate 17 is fixedly connected between the two protruding strips 16. Since the sliding column 9 slides inside the slot 14, when the connecting rod 13 swings around the positioning shaft 15, the position of the slot 14 changes, thereby pushing the plate 7 to move.

[0030] The second linkage mechanism 28 includes a connecting plate 29 and a pusher platform 31. The end of the pusher platform 31 is slidably installed in the second slide groove 5. The end of the upper moving block 18 is provided with a first disk 30, and the end of the pusher platform 31 is provided with a second disk 32. The two ends of the connecting plate 29 are respectively connected to the first disk 30 and the second disk 32 through a rotating shaft. Since the end of the connecting plate 29 is connected to the first disk 30 and the second disk 32 through a rotating shaft, when the upper moving block 18 moves upward, the pusher platform 31 will move inward to the side frame 2. At this time, the end of the pusher platform 31 has an inward squeezing effect on the touch plate 17, so that the connecting rod 13 will swing around the positioning shaft 15 as the center, thereby causing the pusher plate 7 to move outward to the side frame 2.

[0031] A fixing plate 11 is fixedly installed at the bottom of the push plate 7. A tension spring 10 is connected between the fixing plate 11 and the side frame 2. When the upper moving block 18 moves downward, the push platform 31 moves to the outside of the side frame 2. The end of the push platform 31 does not cause a squeezing effect on the contact plate 17. At this time, the tension spring 10 can pull the push plate 7 into the side frame 2, so that the push mechanism 6 retracts into the side frame 2.

[0032] The surface of the upper moving block 18 is provided with a frame groove 20, and the top of the frame groove 20 is provided with a sliding groove 21. A welding mechanism 22 is slidably arranged inside the frame groove 20. A slider is provided on the top of the welding mechanism 22 and is slidably installed in the sliding groove 21. The end face of the welding mechanism 22 is connected to a displacement cylinder. When the push plate 7 can drive the support plate 8 to move towards the center of the main body seat 1, the end of the steel plate will move into the frame groove 20. When the end faces of the two steel plates are tightly pressed together, the welding mechanism 22 is located between the two steel plates. Under the action of the displacement cylinder, the welding mechanism 22 slides, thereby realizing the welding operation of the two steel plates.

[0033] A sliding table 23 is slidably installed at the bottom of the frame groove 20. A baffle 25 is provided on the end face of the sliding table 23 at the deepest part of the frame groove 20. Multiple slots 26 are evenly opened on the surface of the sliding table 23. Ball bearings 27 are rotatably installed inside the slots 26. A second cylinder 24 is provided on the outer surface of the upper moving block 18. The output end of the second cylinder 24 is connected to the sliding table 23. The welding mechanism 22 is located above the sliding table 23. When the tension spring 10 can pull the push plate 7 into the side frame 2, the surface of the welded steel plate is inside the frame groove 20. Under the action of the second cylinder 24, the sliding table 23 can be pushed out of the frame groove 20. Thus, the welded steel plate is pushed to the outside of the frame groove 20 by the baffle 25. Under the action of the ball bearings 27, the worker can remove the welded steel plate with less effort.

[0034] Working principle: First, due to the weight of the steel plates themselves, the bottom steel plate of the collection frame 3 will fall onto the surface of the support plate 8. When the moving block 18 moves upward, the pushing platform 31 will move inward towards the side frame 2. At this time, the end of the pushing platform 31 exerts an inward squeezing force on the contact plate 17, causing the connecting rod 13 to swing around the positioning shaft 15. This allows the pushing plate 7 to move the support plate 8 towards the center of the main body 1, and the end faces of the two steel plates will stick together. At this time, the top of the pushing plate 7 will seal the opening at the bottom of the collection frame 3, preventing the steel plates inside the collection frame 3 from falling further. Then, under the action of the displacement cylinder... The welding mechanism 22 moves at the joint of the two steel plates to perform welding operations on the two steel plates. Then, the upper block 18 moves downward and the pushing table 31 moves to the outside of the side frame 2. The end of the pushing table 31 does not cause a squeezing effect on the contact plate 17. At this time, the tension spring 10 can pull the pushing plate 7 into the side frame 2, causing the pushing mechanism 6 to retract into the side frame 2. At the same time, under the action of the second cylinder 24, the sliding table 23 can be pushed to the outside of the frame groove 20. Thus, the welded steel plate is pushed to the outside of the frame groove 20 by the baffle 25. Under the action of the ball bearing 27, the worker can remove the welded steel plate more easily.
