Abstract
Description
A combined gas shielded welding machine Technical Field
[0001] This utility model belongs to the technical field of gas shielded welding equipment, specifically relating to a combined gas shielded welding machine vehicle. Background Technology
[0002] In construction sites and similar environments, gas shielded welding equipment needs to be placed according to the site requirements. During construction, the welding machine often needs to be constantly moved to adapt to the work needs. Moving the welding machine involves the welding machine, welding torch, gas cylinder, and other tools required for welding. Often, one vehicle is needed to transport the welding machine, another to transport the gas cylinder, and yet another for the other tools, impacting work efficiency. If everything is packed into one vehicle, the entire vehicle needs to be moved when changing the gas cylinder, which is inconvenient. Furthermore, the placement of the gas cylinder during welding is difficult; usually, without support, it can only be stood upright next to the welding machine or supported by a small cart, making it prone to tipping over and posing a safety hazard. Therefore, a welding machine cart is needed to solve these problems. Summary of the Invention
[0003] To address the problems existing in the prior art, a combined gas shielded welding machine is proposed.

[0005] Preferably, the gas cylinder rack includes a base plate, with uprights connected to the base plate, rollers connected to the bottom of the uprights, a U-shaped frame connected to the middle of the uprights, mounting rods connected to both ends of the U-shaped frame, ear plates connected to one side of the U-shaped frame, and a buckle connected to the other side of the U-shaped frame. A fixing chain is connected between the buckle and the ear plates, and the buckle and the fixing chain are detachably connected. The fixing chain and the U-shaped frame enclose a fixed space for fixing the gas cylinder.
[0006] Preferably, a horizontal bar is connected to the end of the upright, and a limiting chain is connected to the corresponding base; a hook is connected to the end of the limiting chain, and the hook can be hung on the horizontal bar to fix the gas cylinder rack.
[0007] Preferably, a gas cylinder tray is connected to the base plate, and the bottom of the gas cylinder can be inserted into the gas cylinder tray to fix the gas cylinder.
[0008] Preferably, the bottom of the mounting groove is arc-shaped, and the corresponding mounting rod is cylindrical, allowing the mounting rod to rotate within the mounting groove.
[0009] Preferably, a baffle is provided in the middle of the base, and the middle of the gas cylinder rack can be blocked by the baffle to make the gas cylinder rack stand upright.
[0010] Preferably, rain shields are connected to the top of both ends of the welding machine housing.
[0011] Preferably, the base is also provided with a welding rod bucket for placing welding rods and a tool cylinder for storing tools, and a fixing hook for placing welding torches is connected to the side plate.
[0012] Preferably, the base is also equipped with a pusher handle for pushing the cart forward.

[0014] 1. This utility model achieves the separation and connection of the gas cylinder rack and the welding machine through the mounting groove and the mounting rod set on the gas cylinder rack, so that the gas cylinder rack can be transferred together when the whole machine needs to be transferred, and can be separated and transferred separately when the gas cylinder needs to be replaced individually.
[0015] 2. This utility model achieves horizontal transport of the gas cylinder rack by connecting the gas cylinder rack with the limiting chain, reducing the damage to the gas cylinders on the rack caused by impacts from large stones on the road surface during movement. When in use, it is protected by leaning against the baffle to ensure that it will not move easily. Attached Figure Description

[0024] Example 1:
[0025] Please refer to Figures 1-4. To facilitate the transportation of welding machines and gas cylinders during construction, this embodiment proposes a combined gas shielded welding machine vehicle, including a base 1, a welding machine housing 2 connected to the base 1, and a gas cylinder rack 3. Side plates 4 are connected to both sides of the base 1, and mounting slots 31 are opened on the top of the side plates 4. Mounting rods 41 are connected to the gas cylinder rack 3. During installation, the mounting rods 41 are simply inserted into the mounting slots 31 to connect the gas cylinder rack 3 to the base 1. The gas cylinder rack 3 can be placed horizontally or vertically as needed to adapt to different application scenarios. Wheels 5 are connected to the bottom of the base 1. The wheels 5 can be braked to stop and thus fix the welding machine during construction.
[0026] Example 2:
[0027] Referring again to Figures 1-4, in another embodiment, the gas cylinder rack 3 adapted thereto includes a base plate 32, with uprights 33 connected to the base plate 32, rollers 34 connected to the bottom of the uprights 33, and a U-shaped frame 35 connected to the middle of the uprights 33. The U-shaped frame 35 should be positioned low so that the bottom of the gas cylinder rack 3 can fall down when it is placed horizontally after the gas cylinders are installed. Mounting rods 41 are connected to both ends of the U-shaped frame. Ear plates 37 are connected to one side of the U-shaped frame 35, and a buckle 38 is connected to the other side of the U-shaped frame 35. A fixing chain 36 is connected between the buckle 38 and the ear plates 37. The buckle 38 and the fixing chain 36 are detachably connected. The fixing chain 36 and the U-shaped frame 35 enclose a fixing space for fixing the gas cylinders. At the same time, a gas cylinder tray 39 is connected to the base plate 32, and the bottom of the gas cylinder can be inserted into the gas cylinder tray 39 for fixing.
[0028] The end of the upright pole 33 is connected to the horizontal bar 310, and the corresponding base 1 is connected to the limiting chain 12; the end of the limiting chain 12 is connected to the hook 13, which can be hung on the horizontal bar 310 to fix the gas cylinder rack 3. A baffle 8 is provided in the middle of the base 1, and the middle of the gas cylinder rack 3 can be blocked on the baffle 8 to make the gas cylinder rack 3 stand upright.
[0029] When in use, first open the latch 38, insert the gas cylinder into the gas cylinder tray 39, and then lock the fixing chain 36 with the latch 38 to fix the gas cylinder. Then, place the gas cylinder rack 3 vertically, align the two mounting rods 41 with the mounting slots 31 and insert them. If the whole unit needs to be moved, rotate the gas cylinder rack 3 to a horizontal position, and then hook the hook 13 on the limit chain 12 onto the horizontal bar 310 to fix the gas cylinder and the gas cylinder rack 3. When welding is required, loosen the limit chain 12 so that the gas cylinder and the gas cylinder rack 3 can rotate together and lean against the baffle 8.
[0030] Example 3:
[0031] Referring to Figures 1-4, based on Embodiment 2, for ease of installation, the bottom of the mounting groove 31 in this embodiment is arc-shaped, and the corresponding mounting rod 41 is cylindrical. The mounting rod 41 can rotate within the mounting groove 31. Alternatively, the mounting groove 31 can also be rectangular, and the corresponding mounting rod 41 can also be rectangular, so that the gas cylinder rack 3 can have both horizontal and vertical states.
[0032] In addition, rain shields 21 are connected to the top of both ends of the welding machine housing 2 to prevent the welding machine from getting wet in rainy weather.
[0033] Finally, for ease of construction, the base 1 in this embodiment is also provided with several storage areas for tools, such as a welding rod bucket 9 for holding welding rods and a tool bucket 10 for storing tools. The side plate 4 is connected to a fixing hook 6 for holding the welding torch 7. At the same time, for easy pushing, the base 1 is also provided with a trolley handle 11 for pushing the trolley forward.
[0034] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
