Therefore, this utility model provides a steel structure welding device for ship structure construction. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel structure welding device for ship hull construction. It solves the problem that in traditional welding devices, the support area of ​​the welding platform is usually fixed and cannot be dynamically adjusted according to the size and shape of the ship hull components. This makes it difficult to guarantee the stable support of components when welding large or complex ship hull structures, thus seriously affecting the welding quality and precision.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure welding device for ship hull construction, comprising a welding platform, wherein a welding mechanism for the steel structure used in ship hull construction is provided on the welding platform, and the welding mechanism includes:

[0009] Preferably, a fixing plate is fixedly connected to the lower end face of the supporting shell, and a first electric push rod is fixedly connected inside the fixing plate.

[0010] Preferably, a push block is fixedly connected to the telescopic end of the first electric push rod, and movable rods are provided on both sides of the push block through a rotating shaft.

[0014] Beneficial effects

[0015] This utility model provides a steel structure welding device for ship hull construction. Compared with the prior art, it has the following advantages:

[0016] Firstly, the push block of this utility model approaches the first electric push rod, causing the push block to slide inside the support shell, thereby pushing the second auxiliary platform on the slide plate forward and increasing the support area of ​​the front end of the welding platform. Then, when the push block slides, the first auxiliary platform rotates with the push block through the rotating shafts at both ends of the movable rod, and the movable rod pushes the first auxiliary platform. The first auxiliary platform slides on both sides of the welding platform through the sliding rod, which is used to synchronously adjust the support area on both sides of the welding platform. This allows the welding device to be flexibly adjusted according to the different sizes and shapes of ship structure components, ensuring stable support of the components during the welding process, improving welding quality and precision. No matter how the shape of the ship structure component changes, the welding device can provide suitable support, enhancing the adaptability and flexibility of the welding device. When no additional support area is needed, the first and second auxiliary platforms can be retracted to the sides or below the welding platform, reducing the equipment's footprint and improving space utilization.

[0017] Secondly, when the welding bracket is adjusted, this utility model moves the mounting bracket on the welding platform. Then, the clamping plate is raised and lowered via the second electric push rod to clamp the steel structure on the welding platform. This effectively prevents the steel structure from moving or vibrating during welding, thus ensuring the accuracy and stability of the weld joint. Furthermore, the lower end of the clamping plate is equipped with a rubber plate, which acts as a buffer during clamping, preventing scratches or indentations on the steel structure surface and protecting its integrity. As the welding bracket is adjusted, the clamping plate can also be adjusted, facilitating its movement to the welding area for positioning and clamping without manual adjustment, thereby improving the efficiency of the welding operation.

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: a steel structure welding device for ship hull construction, including a welding platform 1, on which a welding mechanism for steel structure construction is provided, the welding mechanism including:

[0025] The adjustment assembly includes a support shell 3 fixedly connected to the lower end face of the welding platform 1, a slide plate 301 slidably connected inside the support shell 3, a second auxiliary platform 302 with an L-shaped structure fixedly connected to one end of the slide plate 301, a slide rod 2 slidably connected inside the welding platform 1, and a first auxiliary platform 201 fixedly connected to one end of the slide rod 2.

[0026] The clamping assembly includes a slide rail bracket 5 fixedly connected to the rear side wall of the welding platform 1. The slide rail bracket 5 has a welding bracket 501 inside which is driven by a screw. The side wall of the welding bracket 501 is provided with a clamping plate 603 connected by a lifting assembly. A rubber plate 604 is fixedly connected to the lower end face of the clamping plate 603.

[0027] In a preferred embodiment, a fixing plate 4 is fixedly connected to the lower end face of the supporting shell 3. A first electric push rod 401 is fixedly connected inside the fixing plate 4. A push block 402 is fixedly connected to the telescopic end of the first electric push rod 401. Movable rods 403 are rotatably connected to both sides of the push block 402 via a rotating shaft. A rotating shaft is provided on the lower end face of the first auxiliary platform 201 and rotatably connected to the other end of the movable rod 403. The push block 402 is fixedly connected to the slide plate 301. When the push block 402 retracts via the first electric push rod 401, the push block 402 moves closer to the first electric push rod 401. The push block 402 drives the slide plate 301 to slide inside the supporting shell 3, thereby pushing the second auxiliary platform 302 on the slide plate 301 forward, increasing the support area of ​​the front end face of the welding platform 1. Then, when the push block 402 moves forward... During sliding, the first auxiliary platform 201 rotates with the push block 402 via the rotating shafts at both ends of the movable rod 403. The movable rod 403 pushes the first auxiliary platform 201, which slides on both sides of the welding platform 1 via the slide rod 2. This allows for synchronous adjustment of the support area on both sides of the welding platform 1, enabling the welding device to be flexibly adjusted according to the different sizes and shapes of the ship structure components. This ensures stable support of the components during welding, improves welding quality and precision, and provides suitable support regardless of the shape of the ship structure components. This enhances the adaptability and flexibility of the welding device. When no additional support area is needed, the first auxiliary platform 201 and the second auxiliary platform 302 can be retracted to the sides or below the welding platform 1, reducing the equipment's footprint and improving space utilization.

[0028] In a preferred embodiment, the upper end of the welding bracket 501 is provided with a slider 502 connected by a screw drive, and the lower end of the slider 502 is provided with a welding head 503. The welding bracket 501 is adjusted horizontally by the screw inside the slide rail bracket 5 under the action of a motor. Then, the slider 502 is adjusted back and forth by the screw inside the upper end of the welding bracket 501, thereby moving the welding head 503 in all directions.

[0029] In a preferred embodiment, the lifting assembly includes a mounting bracket 6 fixedly connected to the side wall of the welding bracket 501. A mounting plate 601 is fixedly connected to the upper end face of the mounting bracket 6. A second electric push rod 602 is fixedly connected inside the mounting plate 601. A clamping plate 603 is located at the telescopic end of the second electric push rod 602. When the welding bracket 501 is adjusted, it drives the mounting bracket 6 to move on the welding platform 1. Then, the clamping plate 603 is lifted and lowered by the second electric push rod 602 to clamp the steel structure on the welding platform 1. This effectively prevents the steel structure from moving or vibrating during the welding process, thereby ensuring the accuracy and stability of the weld joint. The lower end face of the clamping plate 603 is provided with a rubber plate 604, which can play a buffering role during clamping, preventing scratches or indentations on the surface of the steel structure and protecting the integrity of the steel structure surface. As the welding bracket 501 is adjusted, the clamping plate 603 can be adjusted, making it convenient to move the clamping plate 603 to the welding area for positioning and clamping without manual adjustment, thereby improving the efficiency of the welding operation.

[0030] In a preferred embodiment, protective plates 7 are fixedly connected to both sides of the mounting bracket 6, and a telescopic sleeve rod 8 is fixedly connected to the lower end face of the front end of the mounting bracket 6. The protective plates 7 are installed on both sides of the mounting bracket 6 to protect the debris generated during welding and to protect the workers. Then, the telescopic end of the telescopic sleeve rod 8 is fixedly connected to the clamping plate 603 to ensure that the clamping plate 603 extends and retracts along the telescopic sleeve rod 8 when it is lifting, thus ensuring stability.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the welding bracket 501 is adjusted horizontally by the screw inside the slide rail bracket 5 under the action of the motor. Then, the slider 502 is adjusted back and forth by the screw inside the upper end of the welding bracket 501, thereby moving the welding head 503 in all directions. When the welding bracket 501 is adjusted, it drives the mounting bracket 6 to move on the welding platform 1. Then, the clamping plate 603 is raised and lowered by the second electric push rod 602 to squeeze and clamp the steel structure on the welding platform 1. This can effectively prevent the steel structure from moving or vibrating during the welding process, thereby ensuring the accuracy and stability of the weld joint. The lower end of the clamping plate 603 is provided with a rubber plate 604, which can play a buffering role during the clamping process, preventing scratches or indentations on the surface of the steel structure and protecting the integrity of the steel structure surface.

[0033] When the push block 402 retracts via the first electric push rod 401, the push block 402 approaches the first electric push rod 401, and the push block 402 drives the slide plate 301 to slide inside the support shell 3, thereby pushing the second auxiliary platform 302 on the slide plate 301 forward, increasing the support area of ​​the front end of the welding platform 1. Then, when the push block 402 slides, the first auxiliary platform 201 rotates with the push block 402 via the rotating shafts at both ends of the movable rod 403, and pushes the first auxiliary platform 201 through the movable rod 403. The first auxiliary platform 201 slides on both sides of the welding platform 1 via the slide rod 2, which is used to synchronously adjust the support area on both sides of the welding platform 1, so that the welding device can be flexibly adjusted according to the ship structure components of different sizes and shapes.
