Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of metal prefabricated modular housing processing, specifically to a gas-shielded welding machine for welding metal prefabricated modular housing bodies. Background Technology

[0002] In the welding of prefabricated metal container houses, gas-shielded welding machines are the core equipment for ensuring welding quality and efficiency. However, traditional gas-shielded welding machines have two major drawbacks in practical applications: first, the equipment and gas cylinders are bulky and inconvenient to move and use; second, they lack effective fume extraction functions, which seriously affect the construction flexibility and working environment safety of the container welding.

[0003] Metal prefabricated modular housing units are large in size and have dispersed welding points, requiring welding machines that can be flexibly moved to different work locations. However, traditional gas-shielded welding machines are mostly fixed structures or only equipped with simple rollers, requiring multiple people to work together to move them, especially in narrow spaces inside the modular housing or complex outdoor sites. The relocation process is time-consuming and labor-intensive, greatly reducing the mobility of welding operations. For the mass assembly of modular housing units, inconvenient equipment relocation can lead to poor workflow coordination and hinder the overall construction progress.

[0004] Meanwhile, the welding process of the prefabricated modular housing generates a large amount of welding fumes containing metallic dust and harmful gases. Traditional gas-shielded welding machines lack dedicated fume extraction devices, allowing the fumes to diffuse directly into the work environment. Long-term inhalation of welding fumes can severely damage the respiratory system of operators, violating occupational health and safety regulations. Furthermore, the dense fumes obstruct the welder's vision, affecting their observation and control of the molten pool, increasing the probability of welding defects, and consequently reducing the weld strength and sealing performance of the prefabricated modular housing structure. Therefore, developing a gas-shielded welding machine for welding metal prefabricated modular housing prefabricated housing prefabricated units with convenient transfer capabilities and an efficient fume extraction system has become an urgent need for the industry to improve construction experience and product quality. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a gas shielded welding machine for welding metal prefabricated container houses, which solves the technical problem that the equipment and gas tanks in the prior art are bulky and inconvenient to move and use.

[0006] According to one aspect, at least one embodiment of this disclosure provides a gas-shielded welding machine for welding metal prefabricated modular housing bodies, comprising: The assembly includes a frame, a gas shielded welding machine body, and a welding torch. The gas shielded welding machine body is fixed to the frame, and the welding torch is connected to the gas shielded welding machine body. The enclosure and the fume extraction assembly are provided, wherein the enclosure is located at the bottom of the frame and the fume extraction assembly is located between the enclosure and the welding torch section; A gas cylinder and a fixed and movable assembly, wherein the gas cylinder is disposed within the frame body and the fixed and movable assembly is disposed on the frame body; The fixed moving component includes a notch, which is opened on one side of the top of the frame. A sleeve is provided at the bottom of the inner part of the frame. The gas cylinder is vertically inserted into the sleeve and is located in the notch. A fixing block is provided on the surface of the frame. A moving wheel is provided at each of the four opposite corners of the bottom of the frame.

[0007] As a further technical solution, an arc-shaped connecting rod is provided on the side end face of the fixing block, and a sleeve rod is fitted onto the arc-shaped connecting rod, with the sleeve rod and the arc-shaped connecting rod surrounding the gas tank.

[0008] As a further technical solution, the smoke removal assembly includes an inner mesh frame, which is vertically fixed inside the housing. A filter screen and a purification filler are sequentially inserted and connected inside the housing, and a rear cover is installed inside one side of the housing.

[0009] As a further technical solution, the rear cover surface is provided with a pair of outer sleeves, a fan is installed inside the outer sleeves, and a pair of clamping frames are provided at both ends of the side surface of the rear cover, with one end of the clamping frame supported on the surface of the purification packing.

[0010] As a further technical solution, a gas pipe is connected to one side of the box by a threaded screw, a connecting frame is provided at the bottom of the welding gun, one end of the gas pipe is fixed in the connecting frame, and a gas collection hood is fitted to one end of the welding gun.

[0011] As a further technical solution, a cavity tube is provided on the inner surface of the gas collection hood. The cavity tube has an overall rectangular frame structure. An air intake hole is opened on the surface of the cavity tube. One end of the air pipe passes through the surface of the gas collection hood and is connected to the cavity tube.

[0012] As a further technical solution, the inner surface of the notch is a semi-circular arc-shaped structure, and the inner wall of the notch is in contact with the outer surface of the gas tank.

[0013] As a further technical solution, a push rod is provided on the upper end face of the sleeve rod, and a hook is rotatably connected to the upper end face of the fixing block, and the hook is fitted onto the push rod.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the fixed-moving assembly solves the problem of bulky and inconvenient equipment and gas tanks being difficult to move through an integrated design.

[0023] like Figures 1-3 As shown, it illustrates a gas-shielded welding machine for welding metal prefabricated modular housing bodies according to an embodiment of this disclosure, comprising: The frame 1, the gas shielded welding machine body 2, and the welding gun 3 are provided. The gas shielded welding machine body 2 is fixed on the frame 1, and the welding gun 3 is connected to the gas shielded welding machine body 2. The housing 4 and the smoke removal assembly 7 are provided. The housing 4 is located at the bottom of the frame 1, and the smoke removal assembly 7 is located between the housing 4 and the welding torch 3. Gas tank 5 and fixed moving assembly 6, wherein the gas tank 5 is disposed inside the frame 1 and the fixed moving assembly 6 is disposed on the frame 1; The fixed moving component 6 includes a notch 6-1, which is formed on one side of the top of the frame 1. A sleeve 6-2 is provided at the bottom of the frame 1. The gas tank 5 is vertically inserted into the sleeve 6-2 and is located in the notch 6-1. A fixing block 6-3 is provided on the surface of the frame 1. A moving wheel 6-4 is provided at each of the four opposite corners of the bottom of the frame 1. An arc-shaped connecting rod 6-5 is provided on the side end face of the fixing block 6-3. A sleeve rod 6-6 is fitted onto the arc-shaped connecting rod 6-5. The sleeve rod 6-6 and the arc-shaped connecting rod 6-5 surround the gas tank 5.

[0024] In some examples, in order to achieve integrated transfer of gas cylinder 5 and gas shielded welding machine body 2 and meet the mobile operation requirements during welding of metal assembly box 4, a fixed moving component 6 is designed. This component provides vertical installation space for gas cylinder 5 through a notch 6-1 on one side of the top of the frame 1, ensuring that the top of gas cylinder 5 can be exposed after vertical insertion, which is convenient for connection with gas pipe 7-8 of gas shielded welding machine body 2; the sleeve 6-2 at the bottom of the frame 1 is adapted to the bottom of gas cylinder 5, and the gas cylinder 5 is vertically positioned by insertion to prevent gas cylinder 5 from tipping over during movement. The fixing block 6-3 on the surface of the frame 1 provides a support base for the arc-shaped connecting rod 6-5. The arc-shaped connecting rod 6-5 extends from the side end face of the fixing block 6-3 and together with the sleeve rod 6-6 fitted on it, surrounds the gas tank 5 to form a ring-shaped fixing structure. By adjusting the position of the sleeve rod 6-6 on the arc-shaped connecting rod 6-5, it can accommodate gas tanks 5 of different diameters. The lateral limitation is achieved by the fit between the arc-shaped surface and the outer wall of the gas tank 5, preventing the gas tank 5 from shaking inside the frame 1. The four corner casters 6-4 at the bottom of the frame 1 adopt a universal wheel structure, which has 360° turning capability and can drive the entire equipment to move flexibly.

[0025] During operation, the gas cylinder 5 is vertically inserted into the sleeve 6-2. Adjusting the sleeve rod 6-6 ensures that the arc-shaped connecting rod 6-5 and the sleeve rod 6-6 tightly encircle the gas cylinder 5, thus securing it. When the welding position needs to be moved, pushing the frame 1 allows the gas shielded welding machine body 2 and the gas cylinder 5 to move synchronously via the moving wheels 6-4, eliminating the need to separately move the gas cylinder 5 and reducing the labor intensity of operators. The insertion design of the sleeve 6-2 ensures convenient installation of the gas cylinder 5. The ring-shaped fixing of the arc-shaped connecting rod 6-5 and the sleeve rod 6-6 balances adaptability and stability. The universal structure of the moving wheels 6-4 enhances the flexibility of the equipment in container welding scenarios, avoiding work interruptions caused by equipment disassembly and relocation, and ensuring the continuity of the welding process.

[0026] like Figures 1-3 As shown in the figure, the smoke removal assembly 7 in this embodiment includes an inner mesh frame 7-1, which is vertically fixed inside the housing 4. A filter screen 7-2 and a purification filler 7-3 are sequentially inserted and connected inside the housing 4. A rear cover 7-4 is installed inside one side of the housing 4. A pair of outer sleeves 7-5 are provided on the surface of the rear cover 7-4, and a fan 7-6 is installed inside the outer sleeves 7-5. A pair of clamping brackets 7-7 are provided at both ends of the side surface of the rear cover 7-4, with one end of each clamping bracket 7-7 supporting the surface of the purification filler 7-3. A gas pipe 7-8 is connected to one side of the housing 4 by a threaded connection. A connecting frame 7-9 is provided at the bottom of the welding torch 3. One end of the gas pipe 7-8 is fixed in the connecting frame 7-9. A gas collecting hood 7-10 is fitted to one end of the welding torch 3. A cavity tube 7-11 is provided on the inner surface of the gas collecting hood 7-10. The cavity tube 7-11 has a rectangular frame structure. A suction hole 7-12 is opened on the surface of the cavity tube 7-11. One end of the gas pipe 7-8 passes through the surface of the gas collecting hood 7-10 and is connected to the cavity tube 7-11.

[0027] In some examples, to achieve efficient collection and removal of harmful components from welding fumes and improve the welding working environment, a fume extraction component 7 is designed. This component includes a flared hood 7-10 fitted to one end of the welding torch 3, which can be close to the welding point to reduce fume diffusion. The hollow tube 7-11 on the inner surface of the hood 7-10 has a rectangular frame structure, and its coverage area is adapted to the inner wall of the hood 7-10. The suction holes 7-12 on the surface are evenly distributed to capture fumes from multiple angles and avoid local fume leakage. One end of the air pipe 7-8 passes through the surface of the hood 7-10 and connects to the hollow tube 7-11, and the other end is connected to one side of the housing 4 by a threaded connection, forming a fume delivery channel. The vertically fixed inner mesh frame 7-1 inside the housing 4 divides the internal space. The filter screen 7-2 and the purification packing 7-3 are sequentially inserted between the mesh frame. The filter screen 7-2 is used to intercept solid impurities such as welding slag and dust in the fume, while the purification packing 7-3 can adsorb harmful gas components in the fume. The rear cover 7-4 is connected to one side of the housing 4 by bolts. A fan 7-6 is installed inside the outer sleeve 7-5 on its surface. When started, it can create negative pressure inside the housing 4 to provide power for the flow of flue gas. A pair of clamping brackets 7-7 on the side end face of the rear cover 7-4 have an elastic structure. One end is supported on the surface of the purification packing 7-3 to prevent the purification packing 7-3 from shifting under the action of negative pressure.

[0028] During operation, the fan 7-6 activates, creating negative pressure inside the housing 4. Welding fumes are gathered by the gas collection hood 7-10 and enter the gas pipe 7-8 through the suction port 7-12 of the cavity pipe 7-11, before being transported into the housing 4. The fumes first pass through the filter screen 7-2 to filter solid impurities, and then through the purification packing 7-3 to adsorb harmful components. The purified gas is then discharged from the rear cover 7-4. The cooperation between the gas collection hood 7-10 and the cavity pipe 7-11 achieves near-source, high-efficiency fume collection. The staged filtration and adsorption structure ensures the purification effect. The elastic support of the clamping frame 7-7 ensures the stability of the purification packing 7-3. The detachable design of the rear cover 7-4 facilitates the periodic replacement of the filter screen 7-2 and the purification packing 7-3, allowing the fume removal assembly 7 to maintain efficient operation and providing a clean working environment for welding personnel.

[0029] For example, such as Figure 2 As shown, the inner surface of the notch 6-1 is a semi-circular arc-shaped structure, and the inner wall of the notch 6-1 is in contact with the outer surface of the gas tank 5.

[0030] In some examples, the semi-circular arc-shaped structure on the inner surface of the notch 6-1 fits into the outer surface of the gas tank 5, further enhancing the stability of the gas tank 5. The arc-shaped structure increases the contact area between the notch 6-1 and the gas tank 5, preventing the gas tank 5 from shaking due to uneven local stress after vertical installation. At the same time, the fitting arc-shaped surface can provide lateral restraint for the gas tank 5. Together with the bottom sleeve 6-2 and the outer arc-shaped connecting rod 6-5 and sleeve rod 6-6, the gas tank 5 is fixed from multiple directions (top, bottom, left, and right), ensuring that the gas tank 5 remains vertically stable when the equipment is moved.

[0031] For example, such as Figure 1 As shown, a push rod 8 is provided on the upper end face of the sleeve rod 6-6, and a hook 9 is rotatably connected to the upper end face of the fixing block 6-3. The hook 9 is fitted onto the push rod 8.

[0032] In some examples, the push rod 8 on the upper end of the sleeve rod 6-6 facilitates operator adjustment of the sleeve rod 6-6's position, while the hook 9, rotatably connected to the upper end of the fixing block 6-3, is fitted onto the push rod 8 to lock the sleeve rod 6-6 in position. After adjusting the sleeve rod 6-6 so that the arc-shaped structure encircles the gas tank 5, rotating the hook 9 engages the push rod 8, preventing the sleeve rod 6-6 from sliding along the arc-shaped connecting rod 6-5 when the equipment moves or vibrates, thus avoiding loosening of the gas tank 5. This design is convenient to operate; simply rotating the hook 9 completes locking and unlocking, further ensuring the reliability of the gas tank 5's fixation.

[0033] In actual use: Insert the gas canister 5 vertically into the sleeve 6-2 at the bottom of the frame 1. Adjust the sleeve 6-6 on the arc-shaped connecting rod 6-5 so that it and the arc-shaped connecting rod 6-5 together encircle the gas canister 5. Rotate the hook 9 on the fixing block 6-3 to hook the push rod 8 of the sleeve 6-6 and lock it in place. The top of the gas canister 5 is located in the notch 6-1 and connected to the main body 2 of the gas shielded welding machine. Push the frame 1 to the welding point via the moving wheels 6-4. Start the main body 2 of the gas shielded welding machine. Hold the welding torch 3 and aim it at the welding point of the metal assembly box 4. The gas collection hood 7-10 is in contact with the welding area. At the same time, turn on the fan 7-6 of the fume extraction component 7. The fumes generated by welding enter the gas pipe 7-8 through the air intake hole 7-12 of the hollow tube 7-11 inside the gas collection hood 7-10 and are transported to the box 4. The fumes pass through the filter screen 7-2 to filter impurities and the purification filler 7-3 to adsorb harmful components. The purified gas is then discharged. After welding is completed, the equipment is turned off, and the hook 9 is released to adjust the sleeve rod 6-6. The gas tank 5 is then removed for replacement or replenishment, enabling flexible equipment movement and efficient flue gas treatment throughout the process.
