In addition, in the following embodiments, the up, down, left, and right directions are only the directions shown in the drawings, and the installation direction of the gas cylinder moving device is not necessarily limited to these directions.

[0023] Figure 1 and Figure 2 FIG. is a perspective view showing the overall structure of the gas cylinder moving device according to an embodiment of the present invention. AsFigure 1 and Figure 2 As shown in Figure 2 , the cylinder moving device of the present embodiment is used to move a generally cylindrical cylinder storing industrial gases such as compressed air and nitrogen, and may include a main body portion 1, a base portion 2, a fixing portion 4, a first connecting portion 5, rollers 6, an auxiliary supporting portion 7, a second connecting portion 8, and an adjusting device 9.

[0024] As Figure 2 shown in Figure 2 , the main body portion 1 is a frame structure, which is composed of two parallel supporting rods 1a, 1b and a plurality of arc-shaped supporting portions 1c fixed between the two supporting rods 1a, 1b, so that the cylinder can be supported from the side of the cylinder in the space formed by the supporting rods 1a, 1b and the supporting portions 1c. In the present embodiment, four supporting portions 1c are provided, but the number and spacing thereof can be appropriately changed according to the size of the cylinder. In addition, the supporting rods 1a, 1b can also be set as telescopic rods whose lengths can be changed according to the size of the cylinder.

[0025] At one end in the extending direction of the two supporting rods 1a, 1b of the main body portion 1, a gripping portion 3 is formed, and at the other end, a base portion 2 for supporting the cylinder from the bottom surface of the cylinder is fixed, for example, by welding. The base portion 2 is arranged such that its upper surface is substantially perpendicular to the extending direction of the supporting rods 1a, 1b, so that the cylinder can be stably supported by the base portion 2 and the supporting portion 1c when placed in an upright state on the base portion 2.

[0026] A fixing portion 4 for fixing the cylinder is provided on the main body portion 1. In the present embodiment, the fixing portion 4 is composed of a chain whose one end is fixed to one supporting rod, and the cylinder is fixed by fixing the other end of the chain to the other supporting rod after placing the cylinder in the loading space of the main body portion 1. However, the implementation of the fixing portion is not limited thereto, and the fixing portion can also be formed as an annular clamp whose one end is hinged to one supporting rod, an elastic band fixed to the main body portion, or a clamping member in the left-right direction, etc.

[0027] A first connecting portion 5 is rotatably connected to the end of the main body portion 1 where the base portion 2 is provided by a pin shaft. The first connecting portion 5 can rotate relative to the base portion 2 with a pin shaft extending in the width direction of the main body portion 1 as an axis. In the present embodiment, the first connecting portion 5 has two connecting rods 5b, 5c. One ends of the two connecting rods 5b, 5c are respectively rotatably connected to the supporting rods 1a, 1b, and rollers 6 are respectively installed at the other ends. A connecting shaft 5a for connecting the adjusting device 9 described later is connected between the two connecting rods 5b, 5c of the first connecting portion 5. In addition, a brake can also be provided for the rollers 6 to brake the rollers 6 as needed.

[0028] An auxiliary supporting portion 7 for auxiliary supporting the cylinder is also provided on the main body portion 1. As Figure 3As shown, the auxiliary support part 7 is integrally formed as a foldable and deployable folding frame, including an auxiliary support rod 7a, limit rods 7b, 7c, a handle 7d, and an auxiliary wheel 7e. One end of the auxiliary support rod 7a is rotatably connected to the support rods 1a, 1b of the main body part 1 through a rotating shaft 7A, and an auxiliary wheel 7e serving as a universal wheel is installed at the other end. A plurality of limit rods 7b, 7c connected to each other in a hinged manner are rotatably installed between the approximate middle part of the auxiliary support rod 7a and the main body part 1, and the limit rods 7b, 7c can limit the rotation range of the auxiliary support rod 7a. A handle 7d is connected to the hinged part 7B of the limit rods 7b, 7c. Thus, in the Figure 3 shown state, the limit rods 7b, 7c are folded with each other, and the auxiliary support rod 7a is rotated to a position close to the main body part 1, thereby retracting the auxiliary support part 7. When pulling the handle 7d starting from the Figure 3 shown state, the handle 7d drives the hinged part 7B of the limit rods 7b, 7c to move outward, causing the limit rods 7b, 7c to rotate with each other and deploy, and the auxiliary support rod 7a rotates around the rotating shaft 7A in the Figure 3 arrow direction in the figure to a position away from the main body part 1, thereby deploying the auxiliary support part 7. Additionally, a locking device can also be provided at the hinged part of the limit rods 7b, 7c or the like, whereby the limit rods 7b, 7c can be locked in the folded state and the deployed state.

[0029] Above the end of the main body part 1 where the base part 2 is provided, a second connecting part 8 is fixed by welding or the like. In the present embodiment, as Figure 1 shown, the second connecting part 8 is a trapezoidal bracket with both ends respectively fixed to the support rods 1a, 1b. An installation part 8a for installing an adjustment device 9 described later is provided at the middle part of the second connecting part 8.

[0030] Figure 3 is a diagram showing the state before the base part 2 of the gas cylinder moving device is raised, Figure 4 is a diagram showing the state after the base part 2 is raised by the adjustment device 9. Next, with reference to Figure 3 and Figure 4 , the specific structure of the adjustment device 9 in the present utility model will be described.

[0031] The adjustment device 9 is an adjustment device for adjusting the height of the base part 2, and is connected between the connecting shaft 5a of the first connecting part 5 and the installation part 8a of the second connecting part 8.

[0032] In this embodiment, the adjustment device 9 employs a hydraulic lifting structure having a hydraulic cylinder and a piston, etc. The adjustment device 9 may include a lifting rod 9a, a connecting rod 9b, pedals 9c, 9d, etc. One end of the lifting rod 9a is fixedly connected to the mounting portion 8a of the second connecting portion 8 by welding or the like, and the other end is connected to the piston. Thus, the lifting rod 9a can extend and retract relative to the connecting rod 9b through the lifting and lowering of the piston, driving the mounting portion 8a of the second connecting portion 8 to move up and down. One end of the connecting rod 9b is rotatably connected to the connecting shaft 5a of the first connecting portion 5, and the other end is connected to the base of the hydraulic cylinder. Additionally, an activity gap allowing the connecting rod 9b to rotate with respect to the connecting shaft 5a during the lifting and lowering of the lifting rod 9a is provided between one end of the connecting rod 9b and the connecting shaft 5a of the first connecting portion 5. Thus, when the main body portion 1 moves up and down, the main body portion 1 can rotate relative to the connecting rod 9b via the first connecting portion 5. Thereby, one end of the adjustment device 9 is connected to the main body portion 1 via the second connecting portion 8, and the other end is rotatably connected to the main body portion 1 via the first connecting portion 5, and can be telescoped by the lifting and lowering of the lifting rod 9a, thereby driving the main body portion 1 to move up and down to adjust the position of the base portion 2. Moreover, by the lifting rod 9a and the connecting rod 9b of the adjustment device 9, the first connecting portion 5 rotatably connected to the main body portion 1 can be fixed, preventing the first connecting portion 5 from freely rotating relative to the main body portion 1 and maintaining the angle of the first connecting portion 5 relative to the main body portion 1. The pedals 9c and 9d are arranged to be stepped on by an operator. In this embodiment, the pedal 9c can be a pressure pedal for extending the lifting rod 9a, and the pedal 9d can be a pressure relief pedal for retracting the lifting rod 9a. The pedals 9c and 9d can be appropriately selected according to the position of the gas cylinder to adjust the height of the base portion 2.

[0033] When it is necessary to transport the gas cylinder from the storage rack to other workstations, the operator first moves the gas cylinder moving device as Figure 3 shown to the edge of the storage rack and locks the rollers 6. Then, as Figure 4 shown, while holding the gripping portion 3 by hand and keeping the main body portion 1 in a substantially upright state, the operator steps on the pedal 9c, causing the lifting rod 9a to gradually rise. At this time, the lifting rod 9a drives the main body portion 1 to rise via the mounting portion 8a of the second connecting portion 8, and the first connecting portion 5 rotates around the axis relative to the main body portion 1, further causing the base portion 2 to rise to the same height as the storage rack in a state substantially parallel to the ground. After that, the gas cylinder moving device is pushed, the base portion 2 is placed on the storage rack, the gas cylinder on the storage rack is placed on the base portion 2 and fixed by the fixing portion 4. Then, the operator pulls the handle 7d, unfolds and locks the folding auxiliary support portion 7, and tilts the gas cylinder moving device to place the auxiliary wheels of the auxiliary support portion 7 on the ground. In this way, the loading and movement of the gas cylinder can be carried out.

[0034] The gas cylinder moving device with the above structure can adjust the height of the base part 2 by adjusting the device 9, so that the base part 2 can be adjusted to the set height while the gas cylinder moving device remains in a substantially upright state. Therefore, by simply holding the gas cylinder moving device by hand and stepping on the pedal, the height of the base part of the gas cylinder moving device can be adjusted to the height corresponding to the gas cylinder storage position, and the gas cylinder can be loaded and moved by the gas cylinder moving device, which can greatly reduce the burden on the operator, and all operations can be completed by a single person, simplifying the operation process and improving work efficiency. In addition, the gas cylinder always remains in a substantially upright state during the loading process, with a small movement amplitude, and can be moved smoothly.

[0035] In the above embodiment, the adjusting device 9 adopts a hydraulic lifting structure with a hydraulic cylinder and a piston, etc., but it is not limited thereto. The adjusting device can also adopt a mechanical or electric lifting structure using pulleys, guide rails, etc. However, by adopting a structure such as that of the present utility model, precise adjustment of the adjusting device can be achieved with a simple and small structure at low cost, and it is convenient for installation.

[0036] In addition, in the above embodiment, the base part 2 is fixed to the main body part 1 by welding or the like, but it is not limited thereto. The base part 2 can also be installed on the main body part 1 in a manner that can move in the width direction of the gas cylinder moving device through a guide rail or a lead screw and a nut, etc., so that the position of the base part can be adjusted not only in the height direction but also in the left - right direction.

[0037] In addition, in the above embodiment, buffer devices such as springs or anti - slip devices such as rubber can also be provided on the supporting part 1c and the base part 2, etc., so as to be able to move the gas cylinder more smoothly and prevent the gas cylinder from shaking and colliding during the movement.

[0038] The above embodiment shows a preferred embodiment of the present utility model, but the present utility model is not limited thereto. It should be understood that the above - mentioned embodiment is merely exemplary and not restrictive. Without departing from the gist of the present utility model, various obvious or equivalent modifications, substitutions, and combinations that those skilled in the art can make to the above details will be included within the scope of the claims of the present utility model.
