DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The gas filling device according to the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the gas filling device of the embodiment of the utility model may include a mounting frame 100 , a lifting device 200 , a gas filling device 300 and a lifting device 400 .

[0026] The lifting device 200 is arranged on the top of the mounting frame 100 , and the multiple inflation interfaces 301 on the inflation device 300 are respectively arranged on the lifting ends of the lifting device 200 .

[0027] It should be noted that the mounting end of the inflation interface 301 is embedded in the lifting end of the lifting device 200 and is locked by bolts.

[0028] As a possible situation, the inflation interface 301 is connected to a spiral pipe and hangs downward, and a quick locking buckle is connected to the bottom to facilitate quick locking and inflation of the gas cylinder 600.

[0029] The lifting device 400 is arranged below the lifting device 200. Figure 3 As shown, the lifting device 400 includes a first driving cylinder 410 , a sprocket structure 420 , a connecting plate 430 and a lifting arm 440 .

[0030] The first driving cylinder 410 is disposed on the mounting frame 100 via a fixing frame 411 , and the telescopic end of the first driving cylinder 410 extends vertically upward.

[0031] It should be noted that the fixing frame 411 is horizontally arranged and located inside the mounting frame 100 , and the first driving cylinder 410 is mounted on the fixing frame 411 .

[0032] The telescopic end of the first driving cylinder 410 drives the connecting plate 430 to slide up and down in the mounting frame 100 through the sprocket structure 420 .

[0033] It can be understood that the extension of the first driving cylinder 410 can lift the sprocket structure 420, so that the sprocket structure 420 drives the connecting plate 430 to rise.

[0034] The lifting arm 440 is disposed at the bottom of the connecting plate 430 .

[0035] As a possible situation, there are two lifting arms 440 , and the two lifting arms 440 are respectively arranged on the same side of the connecting plate 430 and extend into the mounting frame 100 .

[0036] Specifically, when the relevant staff is filling gas (such as oxygen, nitrogen, argon) in batches, first, the relevant staff places multiple gas cylinders 600 in the placement cart 500 in turn, and pushes the placement cart 500 to move into the mounting frame 100. The lifting arm 440 is then located at the lowest point. As the placement cart 500 is pushed in, the wheels 501 of the placement cart 500 are located on both sides of the lifting arm 440, and the bottom of the placement cart 500 is located directly above the lifting arm 440, until the gas cylinder 600 is directly below the corresponding inflation interface 301.

[0037] Then, the relevant staff controls the extension of the first driving cylinder 410, and the first driving cylinder 410 lifts the sprocket structure 420 upward, so that the sprocket structure 420 drives the connecting plate 430 to slide upward in the mounting frame 100. At this time, the lifting arm 440 lifts the bottom of the vehicle 500 and separates the wheel 501 from the ground until the interface of the gas cylinder 600 is close to the inflation interface 301.

[0038] The relevant staff will connect multiple inflation interfaces 301 to the corresponding gas cylinders 600 in turn, and then perform the inflation operation. During the inflation, since the wheels 501 are separated from the ground, the bottom of the placement vehicle 500 is lifted by the lifting arm 440, and the placement vehicle 500 will not deviate or slide, making the filling more stable.

[0039] In an embodiment of the present invention, the sprocket structure 420 includes a rotating shaft 421 , a sprocket 422 and a chain 423 .

[0040] Among them, the telescopic end of the first driving cylinder 410 is provided with a sleeve 412, the rotating shaft 421 can be rotatably sleeved in the sleeve 412, the sprocket 422 is coaxially arranged on the rotating shaft 421, one end of the chain 423 is connected to the mounting frame 100, and the other end bypasses the sprocket 422 and extends downward, and is connected to the connecting plate 430.

[0041] like Figure 2 As shown, in order to further improve the stability of the sprocket structure 420 when it is lifted, vertical slide grooves 101 are respectively opened on both sides of the mounting frame 100, and the two ends of the rotating shaft 421 are respectively slidably connected to the two slide grooves 101, and the two ends of the rotating shaft 421 are respectively provided with limit heads.

[0042] In order to further improve the lifting stability of the connecting plate 430 , vertical slide rails 431 are respectively provided on the inner walls on both sides of the mounting frame 100 , and the two sides of the connecting plate 430 are respectively slidably connected to the slide rails 431 .

[0043] Specifically, if Figures 1 to 4 As shown, when the relevant staff starts the lifting device 400, the first driving cylinder 410 drives the sleeve 412 to rise, so that the rotating shaft 421 rises along with the sleeve 412. At this time, both ends of the rotating shaft 421 slide in the corresponding slide grooves 101 respectively.

[0044] Due to the gravity of the connecting plate 430 and the lifting arm 440, the chain 423 maintains an engagement state with the sprocket 422, and as the rotating shaft 421 rises, the sprocket 422 rotates on the chain 423 and drives the chain 423 to rise, so that the connecting plate slides in the slide rail 431, and the lifting arm 440 can drive the placement vehicle 500 to rise.

[0045] In one embodiment of the present invention, guide plates 102 are respectively provided on both sides of the bottom of the mounting frame 100 to limit the placement vehicle 500 .

[0046] When the placement vehicle 500 is pushed between the two guide plates 102 , the lifting arm 440 is located at the bottom of the placement vehicle 500 .

[0047] It should be noted that the guide plate 102 is an inwardly protruding arc-shaped plate, and the minimum distance between the two guide plates 102 is consistent with the width of the placement cart 500. When the relevant staff pushes the placement cart 500 to move into the mounting frame 100, the placement cart 500 can enter the predetermined position more accurately due to the limitation on both sides, which can not only ensure that the lifting arm 440 is located at the bottom of the placement cart 500, but also ensure that when the placement cart 500 is lifted, the gas cylinder 600 can be close to the inflation interface 301.

[0048] In one embodiment of the present invention, Figure 1 As shown, the lifting device 200 includes an extension plate 210 , a second driving cylinder 220 and a lifting plate 230 .

[0049] Among them, the extension plate 210 is arranged on the top of the mounting frame 100 and extends inward, the second driving cylinder 220 is arranged on the extension plate 210, the lifting plate 230 is arranged below the extension plate 210 and connected to the telescopic end of the second driving cylinder 220, and the inflation interface 301 is arranged on the lifting plate 230.

[0050] It should be noted that, in order to improve the installation strength of the extension plate 210 , a reinforcing rib is provided at the connection between the extension plate 210 and the mounting frame 100 .

[0051] It is understandable that the lifting device 200 does not need to be adjusted frequently. When the lifting stroke of the lifting device 400 is insufficient or the height of the gas cylinder 600 is small, the relevant staff can start the second driving cylinder 220 so that the second driving cylinder 220 drives the lifting plate 230 to descend, thereby lowering the inflation interface 301 to adapt to more height requirements.

[0052] In one embodiment of the present invention, the inflation device 300 further includes an inflation main pipeline (not shown in the figure), and a plurality of inflation interfaces 301 are respectively connected to the inflation main pipeline.

[0053] The main gas charging pipeline is connected to a gas storage pool or a gas storage tank, and is also connected to an air pump. When filling the gas, the gas in the gas storage pool or the gas storage tank is pumped into the gas cylinder 600 through the air pump.

[0054] In summary, according to the gas filling device of the embodiment of the utility model, by moving the inflation interface 301 of the inflation device 300 upwards, it is possible to avoid problems such as interference and collision caused when the gas cylinder 600 is pushed in. By providing a liftable lifting device 400, when filling the gas, the bottom of the placement vehicle 500 can be lifted so that the wheels 501 are separated from the ground, thereby improving stability during the filling process.
