Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas cylinder handling equipment, and in particular to a welding gas cylinder transfer trolley. Background Technology
[0002] In gas cylinder manufacturing plants, professional inspection stations, and gas filling stations, cylinder testing is a crucial step in ensuring their safe use. The testing process typically involves multiple workstations (such as visual inspection, hydrostatic testing, internal drying, and airtightness testing), requiring frequent cylinder handling. A standard industrial gas cylinder (such as a 40L steel cylinder) weighs 50-70 kg empty, and becomes even heavier when filled, making manual handling difficult. Utility Model Content
[0003] To facilitate the handling and operation of gas cylinders, this application provides a welding gas cylinder transfer trolley.
[0004] The technical solution for a welding gas cylinder transfer trolley provided in this application is as follows: A welding gas cylinder transfer trolley includes a frame, a riser, a lifting rod, a foot-operated hydraulic cylinder, a support plate, a mounting base, a rotating rod, and a strong magnet. The frame has casters at its bottom. The riser is vertically mounted on the frame. The lifting rod is slidably disposed inside the riser. The support plate is connected to the lifting rod and is located below the frame. The mounting base is connected to the top of the lifting rod and is hollow. The rotating rod is rotatably engaged within the mounting base. The mounting base has a connecting hole for the rotating rod to rotate. The strong magnet is embedded in the side wall of the rotating rod. The foot-operated hydraulic cylinder is mounted on the frame, and its piston rod is connected to the lifting rod.
[0005] Preferably, the lifting rod is connected to a first connecting rod, which passes through the riser. The riser has a waist-shaped groove on its side wall for the first connecting rod to pass through and move up and down. The end of the first connecting rod that passes through the riser is connected to a backing plate, which is an arc-shaped plate. A second connecting rod is connected between the backing plate and the bearing plate. A first reinforcing rod is connected between the first connecting rod and the mounting base.
[0006] Preferably, a second reinforcing rod is connected between the frame and the riser, and the second reinforcing rod is an arc-shaped rod.
[0007] Preferably, a bearing seat is connected inside the mounting base, and the end of the rotating rod that passes through the mounting base is connected to the bearing seat.
[0008] Preferably, a handle is connected to the rotating rod, the handle is located at the end of the rotating rod that does not penetrate into the mounting base, and a limiting rod is connected to the mounting base to prevent the handle from rotating to its limit angle, with one limiting rod on each of the opposite sides of the rotating rod.
[0009] Preferably, the riser is connected to a handlebar for the operator to hold.
[0010] In summary, this application includes the following beneficial technical effects: This utility model provides a welding gas cylinder transfer trolley. In use, the trolley is first tilted manually, and then the gas cylinder is tilted and rotated so that its bottom is placed on the support plate. Then, the rotating rod is rotated so that the strong magnetic block is aligned with the side wall of the gas cylinder, which can then attract and fix the gas cylinder on the trolley. When it is necessary to lift the gas cylinder, the lifting rod and the gas cylinder can be lifted by foot-operated hydraulic cylinder. The overall structure of the device is simple and can be operated by a single person. It is convenient to operate, thus achieving the effect of facilitating the handling of gas cylinders and making the operation convenient. Attached Figure Description

[0015] This application discloses a welding gas cylinder transfer trolley. (Refer to...) Figure 1 and Figure 2 The welding gas cylinder transfer trolley includes a frame 1, a riser 2, a lifting rod 3, a foot-operated hydraulic cylinder 4, a support plate 5, a mounting base 6, a rotating rod 7, and a strong magnet 8. The bottom of the frame 1 is connected to casters 11. The riser 2 is vertically installed on the frame 1. The lifting rod 3 is slidably installed inside the riser 2. The support plate 5 is connected to the lifting rod 3 and is located below the frame 1. The mounting base 6 is connected to the top of the lifting rod 3 and is hollow. The rotating rod 7 is rotatably locked inside the mounting base 6. The mounting base 6 has a connecting hole for the rotating rod 7 to rotate. The strong magnet 8 is embedded in the side wall of the rotating rod 7. The foot-operated hydraulic cylinder 4 is installed on the frame 1, and the piston rod of the foot-operated hydraulic cylinder 4 is connected to the lifting rod 3.
[0016] A first connecting rod 31 is connected to the lifting rod 3. The first connecting rod 31 passes through the riser 2. The side wall of the riser 2 has an oblong groove for the first connecting rod 31 to pass through and move up and down. The end of the first connecting rod 31 that passes through the riser 2 is connected to a backing plate 32. The backing plate 32 is an arc-shaped plate. The backing plate 32 can limit the gas cylinder and further improve the stability of fixing the gas cylinder. A second connecting rod 33 is connected between the backing plate 32 and the bearing plate 5. A first reinforcing rod 311 is connected between the first connecting rod 31 and the mounting base 6.
[0017] A second reinforcing rod 12 is connected between the frame 1 and the riser tube 2. The second reinforcing rod 12 is an arc-shaped rod.
[0018] The first reinforcing rod 311 and the second reinforcing rod 12 help improve the overall stability of the trolley structure. The mounting base 6 is connected to a bearing seat 61. The end of the rotating rod 7 that passes through the mounting base 6 is connected to the bearing seat 61. By setting the bearing seat 61 to cooperate with the connecting hole on the mounting base 6, the two ends of the rotating rod 7 are limited, which helps to improve the stability of the rotating rod 7 during rotation.
[0019] A handle 71 is connected to the rotating rod 7. The handle 71 is located at the end of the rotating rod 7 that is not inserted into the mounting base 6. A limiting rod 62 is connected to the mounting base 6 to block the extreme rotation angle of the handle 71. The limiting rod 62 is provided on each of the opposite sides of the rotating rod 7. The handle 71 makes it easy for the operator to rotate the rotating rod 7. The limiting rod 62 can limit the rotation angle of the rotating rod 7, ensuring that the strong magnetic block 8 on the rotating rod 7 can be aligned with the gas cylinder when it is working.
[0020] A handlebar 21 for the operator to hold is connected to the riser 2.
[0021] The implementation principle of a welding gas cylinder transfer trolley in this application embodiment is as follows: When in use, the trolley is tilted manually first, and then the bottom of the gas cylinder is placed on the support plate 5 by tilting and rotating, and the gas cylinder is tilted close to the mounting base 6. Then, the rotating rod 7 is rotated so that the strong magnetic block 8 is aligned with the side wall of the gas cylinder, which can attract and fix the gas cylinder on the trolley. When it is necessary to lift the gas cylinder, the lifting rod 3 and the gas cylinder can be lifted by the foot-operated hydraulic cylinder 4. After that, the handle 21 can be held to push the trolley for transfer.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
