Description

Technical Field

[0001] This utility model relates to the technical field of submerged arc welding auxiliary equipment, specifically to a submerged arc welding device for H-beams. Background Technology

[0002] In the current steel structure manufacturing and construction field, H-beams, as an extremely important structural material, are widely used in various large-scale buildings, bridges, industrial plants, and other projects. H-beams are typically formed by welding two T-beams together in a specific manner, and the quality of this welding directly affects the strength, stability, and safety of the entire structure. Traditional H-beam welding methods have many drawbacks. Regarding welding fixtures, most fixtures have relatively simple structures, offering limited fixation of the H-beam workpiece and making it difficult to ensure that the two T-beams maintain a precise, flush alignment throughout the welding process. During welding, the workpiece is prone to displacement due to external forces or its own weight, leading to uneven weld joints, which in turn affects weld quality and reduces the structure's load-bearing capacity. Furthermore, traditional welding operations lack flexibility in equipment movement. Common welding methods often require frequent manual adjustments to the welding equipment position to adapt to the welding needs of different parts. This not only increases the labor intensity of workers but also makes it difficult to ensure the accuracy of the welding position, easily resulting in incomplete welds or incorrect welds. Simultaneously, traditional welding methods have a low degree of automation and low production efficiency, making it difficult to meet the demands of large-scale, high-efficiency modern industrial production.

[0004] To achieve this objective, the present invention adopts the following technical solution: An H-beam submerged arc welding device includes two sets of left-right mirror-symmetrical H-beam welding fixtures, and a set of movable submerged arc welding guns is provided on the outer area of ​​each H-beam welding fixture. The H-beam welding fixture includes a base, several rear support plates fixedly connected to the upper surface of the base, and several L-shaped inclined plates arranged at equal intervals and fixed at a 45-degree angle to the rear support plates and the upper surface of the base. The H-beam workpiece to be welded is placed at the right-angle bend of the L-shaped inclined plate, and several hydraulic cylinders are fixed at the top of the inclined surface of the L-shaped inclined plate. The telescopic ends of the hydraulic cylinders are connected to telescopic shafts, and the bottom end of the telescopic shafts is fixed with a rubber pressure plate pressing on the H-beam workpiece. An electromagnet is embedded and fixed at the bottom of the inclined surface of each L-shaped inclined plate, and the magnetic attraction surface of the electromagnet is in contact with the side wall of the H-beam workpiece. The mobile submerged arc welding torch includes two electric tracks fixed on the ground of the welding site, and an electric slider that moves linearly back and forth in the inner track of the electric tracks. A vertical pole is fixed to the top of the electric slider, and a submerged arc welding machine is fixedly connected to the top of the vertical pole. The submerged arc welding end of the submerged arc welding machine faces the H-shaped steel workpiece placed on the L-shaped inclined plate.

[0006] As a preferred embodiment of the submerged arc welding device for H-beams, the H-beam workpiece is composed of two T-beams, and the magnetic attraction surface of the electromagnet contacts the joint of the two T-beams to keep the T-beams in a level position.

[0007] As a preferred embodiment of the H-beam submerged arc welding device, the rubber pressure plate has multiple crisscrossing anti-slip patterns on its end face away from the telescopic shaft, and the rubber pressure plate is in contact with the upper surface of the T-beam above, for connecting the two T-beams together.

[0021] like Figures 1 to 3 As shown, this embodiment provides an H-beam submerged arc welding device, including two sets of left-right mirror-symmetrical H-beam welding fixtures 1, and a set of movable submerged arc welding guns 2 set on the outer area of ​​each H-beam welding fixture 1. In the H-beam welding fixture 1, the base 1-1 is placed horizontally on the ground of the welding site, several back support plates 1-2 are fixedly connected to the upper surface of the base 1-1, and several L-shaped inclined plates 1-3 arranged at equal intervals are fixed at a 45-degree angle to the back support plates 1-2 and the upper surface of the base 1-1. The vertical cross section of the L-shaped inclined plate 1-3 is an L-shape inclined at 45 degrees. An H-beam workpiece 1-4 composed of two T-beams is placed at a 45-degree angle at the right-angle bend of the L-shaped inclined plate 1-3. At this time, the magnetic attraction surface of the electromagnet 1-5 is exposed from the opening at the bottom of the inclined surface of the L-shaped inclined plate 1-3 and contacts the joint of the two T-beams, keeping the T-beams in a level position. The controller at the bottom of the base 1-1 controls the synchronous operation of the hydraulic cylinders 1-8. The telescopic shaft 1-7 connected to the telescopic end of the hydraulic cylinder 1-8 extends downward. The rubber pressure plate 1-6 fixed at the bottom of the telescopic shaft 1-7 presses against the upper surface of the T-shaped steel above the H-shaped steel workpiece 1-4. Multiple crisscrossing anti-slip grooves are opened on the end face of the rubber pressure plate 1-6 away from the telescopic shaft 1-7, connecting the two T-shaped steels together. The hydraulic cylinder 1-8, telescopic shaft 1-7, and rubber pressure plate 1-6 are all arranged at an angle of 45 degrees. In the mobile submerged arc welding gun 2, two electric rails 2-1 are fixed on the ground of the welding site. The electric slider 2-2 moves linearly back and forth in the internal rail of the electric rails 2-1. The top of the electric slider 2-2 is fixed with a vertical rod 2-3. The top of the vertical rod 2-3 is fixedly connected to the submerged arc welding machine 2-4. The submerged arc welding end of the submerged arc welding machine 2-4 faces the H-shaped steel workpiece 1-4 placed on the L-shaped inclined plate 1-3 to start submerged arc welding. Example

[0022] An H-beam submerged arc welding device includes two sets of left-right mirror-symmetrical H-beam welding fixtures 1 and two sets of movable submerged arc welding guns 2 on the outer side. After the base 1-1 of the H-beam welding fixture 1 is placed, the rear support plate 1-2 is fixed on its upper surface, and the L-shaped inclined plate 1-3 is fixed at a 45-degree angle to the rear support plate 1-2 and the base 1-1. Another H-beam workpiece 1-4 of a different specification, composed of two T-beams, is prepared and placed at a 45-degree angle at the right-angle bend of the L-shaped inclined plate 1-3, so that the magnetic surface of the electromagnet 1-5 contacts the joint of the two T-beams. The controller at the bottom of the base 1-1 controls the electromagnet 1-5 to be synchronously energized, attracting the T-beams and keeping them aligned. Then, the controller controls the hydraulic cylinder 1-8 to operate synchronously, and the telescopic shaft 1-7 drives the rubber pressure plate 1-6 to press down on the T-beams above the H-beam workpiece 1-4. The anti-slip texture of the rubber pressure plate 1-6 increases friction, achieving the butt joint of the two T-beams. The electric track 2-1 of the mobile submerged arc welding gun 2 is fixed in a suitable position, and the electric slider 2-2 moves in the track, driving the upright 2-3 and the submerged arc welding machine 2-4 to move, so that the submerged arc welding end of the submerged arc welding machine 2-4 is aligned with the H-beam workpiece 1-4 for welding. Example

[0023] An H-beam submerged arc welding device includes two sets of symmetrical H-beam welding fixtures 1 and an outer movable submerged arc welding torch 2. First, the base 1-1, rear support plate 1-2, and L-shaped inclined plate 1-3 of the H-beam welding fixture 1 are installed, with the L-shaped inclined plate 1-3 at a 45-degree angle. An H-beam workpiece 1-4, composed of two T-beams, is selected and placed on the L-shaped inclined plate 1-3 at a 45-degree angle, so that the magnetic surface of the electromagnet 1-5 contacts the joint of the two T-beams. The controller energizes the electromagnet 1-5 to attract the T-beams. Then, the controller controls the hydraulic cylinder 1-8 to operate, and the telescopic shaft 1-7 pushes the rubber pressure plate 1-6 to press against the T-beams above the H-beam workpiece 1-4. The anti-slip texture of the rubber pressure plate 1-6 ensures a stable connection between the two T-beams. For the mobile submerged arc welding gun 2, the electric track 2-1 is fixed at the welding site, and the electric slider 2-2 moves within the track, driving the upright 2-3 and the submerged arc welding machine 2-4 to move, so that the submerged arc welding end of the submerged arc welding machine 2-4 faces the H-beam workpiece 1-4, and the submerged arc welding operation begins.

[0024] Based on the above-described solution, the workflow and principles of this technical solution are explained: When using this H-beam submerged arc welding device, firstly, place two sets of left-right mirror-symmetrical H-beam welding fixtures 1 in a suitable position on the welding site, and fix two electric rails 2-1 on the welding site ground outside the area of ​​the H-beam welding fixtures 1. Next, install the various components of the H-beam welding fixtures 1, fix several rear support plates 1-2 to the upper surface of the base 1-1, and then fix several equidistant L-shaped inclined plates 1-3 at a 45-degree angle to the rear support plates 1-2 and the upper surface of the base 1-1. At this time, the vertical section of the L-shaped inclined plate 1-3 is an L-shape inclined at 45 degrees, and an opening is made at the bottom of the inclined surface of the L-shaped inclined plate 1-3 for embedding and fixing the power supply magnet 1-5. Next, the electromagnet 1-5 is embedded and fixed in the opening, so that the magnetic surface of the electromagnet 1-5 is exposed from the opening. At the same time, the hydraulic cylinder 1-8 is fixed on the top of the inclined surface of the L-shaped inclined plate 1-3, ensuring that the hydraulic cylinder 1-8, the telescopic shaft 1-7 and the rubber pressure plate 1-6 to be installed later are all arranged at an inclination of 45 degrees. The telescopic shaft 1-7 is connected to the telescopic end of the hydraulic cylinder 1-8, and the rubber pressure plate 1-6 is fixed to the bottom end of the telescopic shaft 1-7. Many crisscrossing anti-slip textures are opened on the end face of the rubber pressure plate 1-6 away from the telescopic shaft 1-7.

[0025] After the device is assembled, the H-beam workpiece 1-4, composed of two T-beams, is placed at a 45-degree angle at the right-angle bend of the L-shaped inclined plate 1-3, so that the magnetic surface of the electromagnet 1-5 contacts the joint of the two T-beams. The controller at the bottom of the base 1-1 controls the electromagnet 1-5 to be energized synchronously, and the magnetic force of the electromagnet 1-5 keeps the T-beams in a level position. Then, the controller controls the hydraulic cylinder 1-8 to operate synchronously. The telescopic end of the hydraulic cylinder 1-8 drives the telescopic shaft 1-7 to extend downward. The telescopic shaft 1-7 pushes the rubber pressure plate 1-6 to press against the upper surface of the T-beam above the H-beam workpiece 1-4. The anti-slip texture of the rubber pressure plate 1-6 increases the friction with the T-beam, thus connecting the two T-beams together. After the H-beam workpiece 1-4 is fixed, the mobile submerged arc welding gun 2 is started. The electric slider 2-2 moves linearly back and forth in the internal track of the electric track 2-1, which drives the upright 2-3 fixed on the top of the electric slider 2-2 to move. The submerged arc welding machine 2-4 fixedly connected to the top of the upright 2-3 moves accordingly, so that the submerged arc welding end of the submerged arc welding machine 2-4 faces the H-beam workpiece 1-4 placed on the L-shaped inclined plate 1-3, and the submerged arc welding operation begins. The two sets of mobile submerged arc welding guns 2 can simultaneously weld the H-beam workpiece 1-4 on the two sets of H-beam welding fixtures 1.

[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
