[0036] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] See Figures 1 to 9 The gas cutting cylinder moving device shown includes a vehicle body 3, a first support assembly 1, and a second support assembly 2. The vehicle body 3 includes a front wheel bracket, a rear wheel bracket, and a connecting assembly connecting the front wheel bracket and the rear wheel bracket, wherein:

[0039] The front wheel bracket includes a first upright post 301, a second upright post 302, and a crossbar 303. The first upright post 301 and the second upright post 302 are arranged opposite to each other. The lower part of the first upright post 301 and the lower part of the second upright post 302 are connected to the crossbar 303 through a connecting plate 304. Front moving wheels 312 are respectively provided at opposite ends of the crossbar 303.

[0040] The rear wheel bracket includes a first longitudinal rod 305, a second longitudinal rod 306, and a transverse rod 307 connecting the first longitudinal rod 305 and the second longitudinal rod 306. The first longitudinal rod 305 and the second longitudinal rod 306 are arranged opposite each other and both extend vertically. The upper ends of the first longitudinal rod 305 and the second longitudinal rod 306 are hinged to the first upright rod 301 and the second upright rod 302, respectively. The lower ends of the first longitudinal rod 305 and the second longitudinal rod 306 are connected to the rear movable wheel 313 through a universal wheel screw. The second support is located below the transverse rod 307. The transverse rod 303 is parallel to the transverse rod 307. An acute angle is formed between the first upright rod 301 and the first longitudinal rod 305, and an acute angle is formed between the second upright rod 302 and the second longitudinal rod 306.

[0041] In some embodiments, the front moving wheel 312 is a fixed wheel, and the rear moving wheel 313 is a swivel wheel. The upper ends of the first upright 301 and the second upright 302 are both provided with handles 314, which facilitates the operator to move the device by holding the handles 314.

[0042] In this example, the combination of handrails, casters, and fixed wheels allows people to easily move the gas cylinder and also secure the device. Furthermore, the caster screws connected to the casters can handle different uneven ground surfaces, making it more suitable for use on construction sites.

[0043] In this example, the first support component 1 is adjustable in height relative to the rear wheel bracket and is used to support the ground. When the device stops moving, the first support component 1 is adjusted to make it abut against the ground to support the entire vehicle body 3, making the vehicle body 3 stable and facilitating the placement or unloading of gas cutting cylinders on it, with high safety.

[0044] See Figure 1-2 The first support assembly 1 includes a first branch 101 and a second branch. The first branch 101 extends vertically and is parallel to the first longitudinal rod 305 and the second longitudinal rod 306. The upper end of the first branch 101 is connected to the transverse rod 307 of the rear wheel bracket. The second branch is adjustable in height relative to the lower end of the first branch 101, meaning the second branch can move relative to the first branch 101. The second branch is used to abut against the ground. By operating the second branch, the position of the first support assembly 1 can be adjusted so that the second branch abuts against the ground or moves away from the ground.

[0045] In some embodiments, the second support includes a protrusion 102 and a support plate 103, with the protrusion 102 disposed on the support plate 103. The lower end of the first support 101 is provided with a threaded hole, and the protrusion 102 is provided with an external thread that mates with the threaded hole. The position of the first support assembly 1 is adjusted by the depth to which the protrusion 102 is screwed into the first support 101. When the vehicle body 3 needs to stop at a certain position to place or unload the gas cutting cylinder, the second support is adjusted so that the support plate 103 is lowered until it touches the ground. At this time, the vehicle body 3 is stable and stationary, which facilitates the fixing of the device. After fixing the device, it is convenient to place or unload the gas cutting cylinder. When the vehicle body 3 moves, the second support is adjusted so that the support plate 103 is raised until a gap is maintained between it and the ground. The operation is simple and quick.

[0046] In this example, the second support assembly 2 is connected to the lower part of the front wheel bracket. The second support assembly 2 is used to support the gas cutting cylinder. The second support assembly 2 includes a U-shaped first support plate 201, a second support plate 202, and a limiting member. The lower end of the first upright 301 and the lower end of the second upright 302 are respectively connected to the two ends on the same side of the U-shaped first support plate 201. One end of the second support plate 202 is rotatably disposed in the U-shaped opening of the first support plate 201. The limiting member is used to restrict the rotation position of the second support plate 202.

[0047] When the device is stationary, the first support assembly 1 rests against the ground, and the first support plate 201 and the second support plate 202 are located on the same plane (this plane forms an acute angle with the ground). The first support plate 201 and the second support plate 202 also form an acute angle with the ground (both the first support plate 201 and the second support plate 202 extend upwards away from the rear wheel bracket), meaning they are still at a certain height from the ground. If there is a gas cutting cylinder on the first support plate 201 or the second support plate 202, the second support plate 202 can be rotated downwards, causing the gas cutting cylinder to move downwards. This allows for the unloading of the heavy gas cutting cylinder with relatively little force, eliminating the need for manual labor. The force is used to remove the gas cutting cylinder from the first support plate 201 and the second support plate 202; or the new gas cutting cylinder is moved onto the vehicle body 3, so that the second support plate 202 is rotated downwards, exposing the opening of the first support plate 201. The operator can then move the new gas cutting cylinder along the opening onto the first support plate 201, and then rotate the second support plate 202 back to its original position to restrict the rotation of the second support plate 202 (if the new gas cutting cylinder is directly moved onto the second support plate 202, since the second support plate 202 is still a certain height from the ground, the heavy gas cutting cylinder must be lifted a certain height before it can be placed on the second support plate 202, which requires more manpower and more strength).

[0048] The specific implementation of the gas cutting cylinder moving device in this example is as follows: When it is necessary to place the gas cutting cylinder, first rotate the second support plate 202 so that its other end is away from the first support plate 201, then place the gas cutting cylinder on the first support plate 201 corresponding to the opening of the first support plate 201, and then rotate the second support plate 202 back to its original position, with the gas cutting cylinder resting against the second support plate 202. By setting the first support component 1 and the second support component 2, the support is strengthened to cope with the heavy gas cutting cylinder, thereby improving the service life of the device.

[0049] In some embodiments, the limiting member includes a limiting rod 203 and a limiting cylinder 204. Limiting cylinders 204 are respectively provided on both sides of the bottom surface of the first support plate 201. Each limiting cylinder 204 has a through hole extending along its axial direction. The limiting rod 203 passes through both limiting cylinders 204 and abuts against the second support plate 202, supporting the second support plate 202 and preventing it from rotating relative to the first support plate 201. See also... Figure 6 The limiting rod 203 includes a first section and a second section connected to each other. The first section is cylindrical with the same diameter, and the second section is curved.

[0050] In some embodiments, the device further includes a winding assembly 7, with a relatively long delivery pipeline connected to the gas cylinder wound around the winding assembly 7 for enhanced safety. The winding assembly 7 is located on the side of the rear wheel bracket away from the front wheel bracket, and includes a winding reel 701 and a connecting portion. The winding reel 701 is connected to the rear wheel bracket via the connecting portion. The connecting part includes a U-shaped connector 703 and a connecting post 702. The U-shaped connector 703 is connected to the rear wheel bracket, which can be welded. One end of the connecting post 702 is connected to the winding reel 701, and the other end of the connecting post 702 extends into the U-shaped opening of the U-shaped connector 703 and is connected to the U-shaped connector 703 by fasteners. Specifically, the fasteners include bolts and nuts. The two sides of the U-shaped connector 703 and the connecting post 702 are provided with corresponding and through mounting holes. One end of a bolt passes through one side of the U-shaped connector 703, the connecting post 702, and the other side of the U-shaped connector 703 for a certain distance. The protruding end of the bolt is screwed into a nut to fix the connecting post 702 and the U-shaped connector 703. The advantage of this design is that it facilitates the installation and disassembly of the winding reel 701 and the replacement of the winding reel 701.

[0051] See Figure 1 The connecting assembly includes a connecting frame 308 and two connecting rods 309. The connecting frame 308 is U-shaped. Both ends of the connecting frame 308 are rotatably connected to the first upright 301 and the second upright 302 of the front wheel bracket, respectively. The two outer sides of the connecting frame 308 are rotatably connected to the rear wheel bracket through the two connecting rods 309. That is, one end of the connecting rod 309 is rotatably connected to the connecting frame 308, and the other end of the connecting rod 309 is rotatably connected to the rear wheel bracket.

[0052] In some embodiments, one end of the connecting rod 309 has a corresponding first mounting hole 315 on the connecting frame 308, and the connecting rod 309 is connected to the connecting frame 308 by installing a fastener 310 in the first mounting hole 315; the other end of the connecting rod 309 has a corresponding second mounting hole 316 on the rear wheel bracket, and the connecting rod 309 is connected to the rear wheel bracket by installing a fastener in the second mounting hole; at least one of the first mounting hole and the second mounting hole on the connecting rod 309 is elongated, and the first mounting hole and / or the second mounting hole extends along the length direction of the connecting rod 309.

[0053] In a preferred embodiment, both the first mounting hole and the second mounting hole are elongated, which can adjust the angle between the rear wheel bracket and the front wheel bracket, making it easier and faster to place the gas cylinder and move the device. The front wheel bracket can be folded towards the rear wheel bracket, making efficient use of space and facilitating carrying and transportation.

[0054] In some embodiments, an operating part 311 is provided on the side of the connecting frame 308 away from the front wheel bracket. The operating part 311 is U-shaped. When the vehicle body 3 is folded, the operating part 311 can be folded quickly and easily, making it convenient to transport the device to any location.

[0055] The device in this example also includes a gas cylinder protective cover 4 and an arc-shaped support 5. The gas cylinder protective cover 4 and the arc-shaped support 5 are respectively located on the front and rear sides of the front wheel bracket. The opposite ends of the arc-shaped support 5 are connected to the first upright 301 and the second upright 302, respectively. The arc-shaped support 5 is used to support the gas cutting cylinder. Preferably, multiple arc-shaped supports 5 are provided, and the multiple arc-shaped supports 5 are distributed sequentially along the height direction of the first upright 301 and the second upright 302, with a gap maintained between adjacent arc-shaped supports 5. The gas cylinder protective cover 4 is located above the first support assembly 1. The gas cylinder protective cover 4 is arc-shaped and serves to fix the gas cylinder and provide sun protection.

[0056] In some embodiments, the device further includes a fire extinguisher mounting bracket 6, which is disposed on one side of the front wheel bracket. The fire extinguisher mounting bracket 6 is used to hold fire extinguishers, improving safety. See also Figure 1 The fire extinguisher mounting bracket 6 includes an upper ring, a lower ring, and multiple columns connecting the upper and lower rings. A support column is provided inside the lower ring, and the column is parallel to the second upright 302.

[0057] The advantages of the gas cutting cylinder moving device in this example are as follows: When the device stops moving, the first support component is adjusted to abut against the ground to support the entire vehicle body, making the vehicle body stable and facilitating the placement or unloading of gas cutting cylinders, ensuring high safety; by setting a second support component, heavy gas cutting cylinders can be unloaded or new gas cutting cylinders can be moved onto the vehicle body with less force, making operation convenient and quick; the cylinder protective cover serves to fix the cylinder and provide sun protection; the device is more flexible, folds easily and conveniently, and is easy to carry after folding; the device is highly practical and has a long service life.
