Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding equipment for repairing ship parts. Background Technology

[0002] Ships are means of transportation that can navigate or anchor in waterways for transport or operations, and they have different technical performance, equipment, and structural types depending on different usage requirements.

[0003] Reference patent (Publication No.: CN217750098U; Publication Date: 2022-11-08) discloses a steel plate welding device for ships, belonging to the field of ship welding tools. It includes a tooling table; two conveying units symmetrically arranged at opposite ends of the tooling table, used to convey steel plates to be welded; and two positioning units, each located on the upper surface of the tooling table and surrounded by the two conveying units, used to position the steel plates to be welded. The conveying units enable rapid conveying and joining of two steel plates during welding. The positioning units allow workers to quickly position the two steel plates, preventing misalignment during welding and improving welding stability. The welding units enable rapid welding of two steel plates, significantly improving worker efficiency.

[0004] Based on the aforementioned patent, during the use of ships, long-term seawater erosion and mechanical wear cause the plates of parts to break, requiring welding. However, welding is usually only performed on the upper surface of the parts, resulting in low weld strength. Furthermore, when welding both sides of the parts, it is often necessary to re-clamp and reposition the parts to adjust them to the appropriate welding surface, which is a cumbersome process. At the same time, some existing welding equipment is not capable of handling the harmful gases generated during the welding process. Welding produces various harmful gases such as ozone, nitrogen oxides, carbon monoxide, and hydrogen fluoride, as well as dust particles. Many devices lack effective measures for collecting and purifying harmful gases, which can easily diffuse in the working environment. Operators exposed to such an environment for a long time will inhale a large amount of harmful gases, posing a serious threat to their health. Therefore, this utility model provides a welding device for repairing ship parts. Utility Model Content

Additionally, some existing welding equipment lacks the capacity to handle harmful gases generated during welding. Welding produces various harmful gases such as ozone, nitrogen oxides, carbon monoxide, and hydrogen fluoride, as well as dust particles. Many devices lack effective measures for collecting and purifying these harmful gases, allowing them to easily diffuse in the working environment. Long-term exposure to such an environment can cause operators to inhale large amounts of harmful gases, posing a serious threat to their health.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for repairing ship parts, comprising a mounting frame, wherein the mounting frame is provided with a mounting mechanism for welding and processing ship parts for repair, and the mounting mechanism includes:

[0007] The flipping assembly includes a support shaft rotatably connected inside the mounting frame. One end of the support shaft is fixed to a processing platform.

[0014] Beneficial effects

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

[0016] Firstly, this utility model allows the processing platform to rotate on the mounting frame via a support shaft. Simultaneously, the adjustment plate fixed to the outer wall of the support shaft rotates to another set of locking brackets and is locked with screws, enabling welding work on the other side of the part without re-clamping the part, saving clamping time and thus improving the overall welding efficiency. Double-sided welding is achieved through rotation, avoiding errors that may occur due to re-clamping and positioning, and improving the welding strength.

[0017] Secondly, the suction shell of this utility model is fixed to the lower end face of the mounting block and connected to the processing shell via a flexible hose. Harmful gases generated during welding are drawn into the processing shell. Inside the processing shell, a filter support and an activated carbon body are installed via a mounting plate. Dust in the harmful gases first comes into contact with the filter support for filtration, preventing dust particles from entering subsequent purification stages or being emitted into the air, thus reducing the burden on the activated carbon body. Then, the harmful gases are filtered through the activated carbon body. The activated carbon body has a rich pore structure and a large specific surface area, which can effectively adsorb harmful substances such as ozone, nitrogen oxides, carbon monoxide, and hydrogen fluoride in the harmful gases. After two-stage filtration, the content of harmful substances in the discharged gas is greatly reduced, ensuring that harmful gases are collected at the source, reducing the diffusion of harmful gases in the working environment, reducing the risk of operators being exposed to harmful gases, and protecting the health of operators.

A U-shaped frame 501 and adjusting blocks 6 are driven by a lead screw and a motor, adjusting the position of the welding gun 603 connected via a third electric push rod 601. This allows the welding gun 603 to move quickly and accurately to the desired welding position.

The suction housing 508 is fixed to the lower end face of the mounting block 602 via a flexible... Pipe 507 is in a flow connection with the processing housing 502. Harmful gases generated during welding are drawn into the processing housing 502.

Dust in the harmful gases first comes into contact with the filter support 505 for filtration, preventing dust particles from entering subsequent purification stages or being emitted into the air, thus reducing the burden on the activated carbon body 504. Then, the harmful gases are filtered through the activated carbon body 504. The activated carbon body 504 has a rich pore structure and a large specific surface area, which can effectively adsorb harmful substances such as ozone, nitrogen oxides, carbon monoxide, and hydrogen fluoride in the harmful gases. After two-stage filtration, the content of harmful substances in the discharged gas is greatly reduced, ensuring that harmful gases are collected at the source, reducing the diffusion of harmful gases in the working environment, reducing the risk of operators being exposed to harmful gases, and protecting the health of operators.

Then, the two sets of mounting brackets 3 are driven by the first electric push rod 305 to open and close the slider bracket 306 on the surface of the processing platform 201. The limiting plate 301 on the side wall of the mounting bracket 3 pushes and clamps the part, so that the part can be accurately placed in the predetermined position, providing a precise positioning basis for subsequent welding work. Then, the parts to be welded come into contact with each other, and the limiting block 402 is driven by the second electric push rod 401 to clamp and push the welding joint of the parts to align them and prevent the welding joint from shifting. Finally, the screw bolt 303 is rotated to lower the clamping plate 302 on the inner wall of the mounting bracket 3 to press down and clamp the upper end face of the part. Then, the U-shaped frame 501 and the adjusting block 6 are distributed. Driven by a lead screw and motor, the welding gun 603, connected to the third electric push rod 601, is positioned so that it can move quickly and accurately to the welding position. During welding, the suction pipe 506 is activated, creating negative pressure inside the processing housing 502. The suction housing 508 is fixed to the lower end of the mounting block 602 and is connected to the processing housing 502 via a hose 507. Harmful gases generated during welding are drawn into the processing housing 502. Inside the processing housing 502, a filter support 505 and an activated carbon body 504 are installed via a mounting plate 503. Dust in the harmful gases first comes into contact with the filter support 505 for filtration, preventing dust particles from entering subsequent purification stages or being released into the air.

[0033] After the other side of the part is welded, the processing platform 201 is rotated on the mounting frame 1 via the support shaft 2. At the same time, the adjustment plate 203 fixed on the outer wall of the support shaft 2 is rotated onto another set of locking brackets 202 and locked with screws, so that the other side of the part can be welded without re-clamping the part, saving clamping time and improving the efficiency of the overall welding work. Double-sided welding is achieved by rotation.
