Description

Technical Field

[0001] This utility model relates to the field of bridge structural component welding technology, specifically a bridge structural component welding device with an anti-vibration structure. Background Technology

[0002] Bridge structural components refer to various metal, reinforced concrete, or other material components that make up the main structure of a bridge. These components are assembled together by welding, bolting, or other methods to form an integrated structure with functions such as load-bearing, force transmission, and seismic resistance. Bridge structural component welding equipment is a type of specialized machinery used for welding bridge metal structural components. It integrates multiple technologies and components, aiming to achieve an efficient, precise, and stable welding process to ensure the quality and safety of bridge structural components.

[0003] According to Chinese Patent CN202322604145.X, in this application, a third rotary motor installed inside the support plate rotates and drives a threaded rotating rod to move up and down with a connecting rod. At the same time, a welding head is installed on the connecting rod to control the height of the welding point by controlling its up and down movement through the third rotary motor during the welding process. This is beneficial for better welding work, and if slippage occurs during the work, the support plate can block it to prevent it from rolling out and causing secondary damage.

[0004] Although the third rotary motor, threaded rotating rod, and connecting rod in the application can effectively address the slippage problem during welding, in actual use, the welding of bridge structural components requires different angles such as 45 degrees and 90 degrees. Measuring the angle solely by the welder's eyesight introduces errors, leading to a decrease in welding quality. Therefore, we propose a bridge structural component welding device with an anti-vibration structure. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 A bridge structural component welding device with an anti-vibration structure includes a base 1, a first bridge structural component 2, and a second bridge structural component 3. The top of the base 1 is movably connected to the first bridge structural component 2, and the top of the first bridge structural component 2 is movably connected to the second bridge structural component 3. The device also includes:

[0027] An angle-adjusting welding structure is installed between the first bridge structural member 2 and the second bridge structural member 3. This structure is used to weld bridge structures with different angle requirements.

[0028] A lifting structure is installed at the top of the base 1. This structure is used to adjust the angle of the welding structure according to the height of the bridge structure.

[0029] Furthermore, the top of the base 1 is provided with three sets of movable slots 4, and the three sets of movable slots 4 are in the shape of "T". The inner wall of one set of movable slots 4 is fitted with a slider 5, and the top of the slider 5 is fixedly connected to a first threaded rod 6. The outer side of the first threaded rod 6 is fitted with a first nut 7 at the corresponding position on the top of the base 1. The first bridge structure 2 is placed on the top of the base 1. According to the height of the first bridge structure 2, the lifting structure needs to be adjusted to adapt to the height of the first bridge structure 2, which facilitates measurement and welding. Rotating the first nut 7 moves it on the first threaded rod 6, thereby adjusting the position of the slider 5 in the movable slot 4, which provides a basis for subsequent lifting.

[0030] Furthermore, the lifting structure includes a second nut 8, a support plate 9, a sleeve shaft 10, and a second threaded rod 11. The outer side of the first threaded rod 6 is threadedly connected to the top of the first nut 7 with the second nut 8 at the corresponding position. The top of the second nut 8 is fixedly connected to the support plate 9. The sleeve shaft 10 is sleeved on the outer side of the support plate 9. The second threaded rod 11 is fixedly connected to the outer side of the sleeve shaft 10. Then, the second nut 8 is rotated, causing it to move up or down on the first threaded rod 6. Since the support plate 9 is on top of the second nut 8 and is fixedly connected, the support plate 9 will rise or fall accordingly. When the support plate 9 rises or falls, it will drive the sleeve shaft 10 and the second threaded rod 11 to rise or fall together.

[0031] Furthermore, the angle-adjusting welding structure includes an angle measuring block 12 and an auxiliary block 17. Two sets of angle measuring blocks 12 are movably connected to the outer sides of the first bridge structural component 2 and the second bridge structural component 3. An auxiliary block 17 is movably connected to the side of the two sets of angle measuring blocks 12 that is close to each other. The auxiliary block 17 and the two sets of angle measuring blocks 12 are composed of triangles and rectangles. Then, by rotating the two sets of angle measuring blocks 12, the third nut 15 rotates on the outer side of the second threaded rod 11, thereby causing the angle measuring blocks 12 to rotate and adjust to a suitable angle. The angle measuring blocks 12 can be adjusted to 45 degrees, 90 degrees, and 135 degrees. After the height of the sides of the two sets of angle measuring blocks 12 is adjusted, the first bridge structural component 3 can be adjusted to a suitable angle. Component 2 is fixed in place, and then the second bridge structure component 3 is placed on top of the first bridge structure component 2. At this time, the first bridge structure component 2 and the second bridge structure component 3 are also movably connected. The other side of the second bridge structure component 3 is close to the other side of the angle measuring block 12, and then welding is performed. The annular magnet 16 inside the auxiliary block 17 can generate a certain attraction force on the first bridge structure component 2 and the second bridge structure component 3, so as to avoid the operator from manually holding the first bridge structure component 2 and the second bridge structure component 3 and being injured during the welding process. The auxiliary block 17 serves two purposes: one is to place the annular magnet 16, and the other is to increase the thickness of the angle measuring block 12 to accommodate the first bridge structure component 2 and the second bridge structure component 3 with different widths.

[0032] Furthermore, five sets of connecting holes 13 are provided on the outer side of the auxiliary block 17 and the two sets of angle measuring blocks 12. A third threaded rod 19 is inserted into the inner wall of the five sets of connecting holes 13. One end of the third threaded rod 19 passes through the auxiliary block 17 and the two sets of angle measuring blocks 12. A fourth nut 20 is threadedly connected to the outer side of one set of angle measuring blocks 12 and the outer side of the third threaded rod 19 through a washer. The third threaded rod 19 is inserted into the inner wall of the five sets of connecting holes 13 in order to connect the two sets of angle measuring blocks 20 together through the fourth nut 20.

[0033] Furthermore, a first placement groove 14 is provided on the outer side of both sets of angle measuring blocks 12, and a first placement groove 14 is provided on the outer side of the auxiliary block 17. A ring magnet 16 is snapped into the inner wall of the first placement groove 14. The first placement groove 14 and the first placement groove 15 are for placing the third nut 15 so that it can be connected to the two sets of angle measuring blocks 12.

[0034] Furthermore, a third nut 15 is fixedly connected to the inner wall of the first placement groove 14 and the inner wall of the annular magnet 16, and the inner wall of the third nut 15 is movably connected to the outer side of the second threaded rod 11.

[0035] Working principle:

[0036] Preparation and placement stage:

[0037] The first bridge structural component 2 is placed on top of the base 1. Based on the height of the first bridge structural component 2, the lifting structure needs to be adjusted to accommodate its height for convenient measurement and welding. The first nut 7 is rotated and moved on the first threaded rod 6, thereby adjusting the position of the slider 5 in the movable groove 4. This provides the basis for subsequent lifting. Next, the second nut 8 is rotated, causing it to move up or down on the first threaded rod 6. Since the support plate 9 is above the second nut 8 and fixedly connected, the support plate 9 will rise or fall accordingly. When the support plate 9 rises or falls, it will drive the sleeve shaft 10 and the second threaded rod 11 to rise or fall together. Then, the two sets of angle measuring blocks 12 are rotated, causing the third nut 15 to rotate outside the second threaded rod 11, thereby causing the angle measuring blocks 12 to rotate. The angle measuring blocks 12 are adjusted to a suitable angle, allowing them to... The angles can be adjusted to 45 degrees, 90 degrees, and 135 degrees. After the height of the two sets of angle measuring blocks 12 is adjusted, the first bridge structure 2 can be fixed. Then, the second bridge structure 3 is placed on top of the first bridge structure 2. At this time, the first bridge structure 2 and the second bridge structure 3 are also movably connected. The other side of the second bridge structure 3 is close to the other side of the angle measuring block 12, and then welding is performed. The annular magnet 16 inside the auxiliary block 17 can generate a certain attraction force on the first bridge structure 2 and the second bridge structure 3, so as to avoid the operator from manually holding the first bridge structure 2 and the second bridge structure 3 and getting injured during the welding process. The function of the auxiliary block 17 is to place the annular magnet 16 and to increase the thickness of the angle measuring block 12 to accommodate the first bridge structure 2 and the second bridge structure 3 with different widths.
