[0002] The transfer device of gas cylinders is mostly composed of a walking device (such as a cart) and is matched with a plurality of fixing frames. When the gas cylinders are transferred, the plurality of cylinders are sequentially placed in different fixing frames to prevent collision between the gas cylinders during the transfer process.

[0003] However, when this method is used for actual transportation, if the fixing frame is too large, the gas cylinder will shake inside the fixing frame or even collide with the fixing frame. For flammable and active gases such as high-purity oxygen and acetylene, higher stability is required for transportation.

[0004] If the matching degree between the fixing frame and the gas cylinder is high, especially for the gas cylinder after filling, due to the increased weight, manual placement and removal of the gas cylinder requires the gas cylinder to be placed vertically into the opening of the fixing frame, which is difficult to operate.

DETAILED DESCRIPTION

[0025] 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.

[0026] The high-stability transport device for gas cylinders according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 As shown, the high-stability transfer device for gas cylinders according to the embodiment of the utility model may include a transfer vehicle 100 , a pushing device 200 , a pushing plate 300 and a clamping device 400 .

[0028] Wherein, openable and closable baffles 101 are respectively provided on both sides of the transfer vehicle 100 .

[0029] It should be noted that after the baffle 101 is opened, the top of the baffle 101 overlaps the ground, providing an inclined platform for subsequent loading and unloading of the gas cylinder 500.

[0030] The pushing device 200 is disposed in the transfer vehicle 100 , and two push plates 300 are respectively slidably disposed in the transfer vehicle 100 along the direction of the corresponding baffles 101 , and the opposite surfaces of the two push plates 300 are respectively disposed on the pushing ends on both sides of the pushing device 200 .

[0031] It should be noted that the pushing ends on both sides of the pushing device 200 can be pushed or retracted synchronously to push the two pushing plates 300 respectively.

[0032] A plurality of clamping devices 400 are respectively disposed on each push plate 300 . The clamping device 400 includes a mounting plate 410 , a first driving motor 420 and a clamping arm structure 430 .

[0033] Among them, the mounting plate 410 is set on the top of the push plate 300, the two clamping arm structures 430 are meshed with each other and can be rotatably set on the mounting plate 410 respectively, the first drive motor 420 is set on the mounting plate 410, and the output end of the first drive motor 420 is coaxially connected to the rotation axis of one of the clamping arm structures 430.

[0034] It can be understood that, by starting the first drive motor 420 , the two mutually meshing clamping arms can be brought closer to or away from each other, so as to clamp or cancel the gas cylinder 500 .

[0035] Specifically, if Figure 6 As shown, when the relevant staff transports the gas cylinder 500, first, the relevant staff opens the baffles 101 on both sides and makes the baffles 101 contact with the ground to form an inclined platform. Since the weight of the air cylinder 500 is not large, the relevant staff can push the gas cylinder 500 upward along the inclined platform into the transfer vehicle 100, or directly carry the gas cylinder 500 and place it in the transfer vehicle 100.

[0036] Then, the relevant staff can start the clamping device 400 so that the multiple clamping devices 400 respectively clamp the corresponding gas cylinders 500, that is, the relevant staff turns on the first drive motor 420, and the first drive motor 420 drives the clamping arm structure 430 connected thereto, and the two mutually meshing clamping arm structures 430 approach each other and clamp on both sides of the gas cylinder 500 respectively, thereby clamping the gas cylinder 500.

[0037] Next, the relevant staff closes the baffle 101 and pushes the transfer vehicle 100 to the filling position to fill the gas cylinder 500. After the filling is completed, the relevant staff pushes the transfer vehicle 100 to the placement position, reopens the baffle 101, and then turns on the pushing device 200. The pushing ends on both sides of the pushing device 200 push the baffles 101 on both sides respectively, so that the clamping device 400 on the baffle 101 can push the gas cylinder 500 out from the side of the transfer vehicle 100.

[0038] The relevant staff can control the clamping force of the clamping device 400 so that the gas cylinder 500 can slide slightly with the gas cylinder 500 when it is pushed onto the inclined baffle 101. The gas cylinder 500 then slides slowly downward along the inclined baffle 101 until the pushing device 200 pushes the gas cylinder 500 to the ground. The relevant staff can then open the clamping device 400 and reset the pushing device 200 to unload the filled gas cylinder 500.

[0039] In one embodiment of the present invention, Figure 5 As shown, the clamping arm structure 430 includes a gear 431 , a rotating frame 432 , a clamping arm 433 and a ring sleeve 434 .

[0040] The gear 431 is rotatably disposed on the mounting plate 410 , the rotating frame 432 is coaxially disposed with the gear 431 , the clamping arm 433 is disposed at the end of the rotating frame 432 , and a plurality of ring sleeves 434 are respectively embedded and rotatably disposed on the clamping arm 433 .

[0041] The gears 431 in the two clamping arm structures 430 are meshed with each other, and the output end of the first driving motor 420 is coaxially connected to the gear 431 in one of the clamping arm structures 430 .

[0042] It should be noted that the clamp arm 433 is an arc-shaped circular tube structure, and a certain gap is maintained between the inner ring of the ring sleeve 434 and the outer ring of the clamp arm 433 to facilitate the rotation of the ring sleeve 434.

[0043] Specifically, when the relevant staff controls the clamping device 400, the clamping arm structure 430 clamps the outer wall of the gas cylinder 500, that is, the outer wall of the ring sleeve 434 is clamped with the outer wall of the gas cylinder 500, and with the push of the pushing device 200, when the gas cylinder 500 is pushed to the side onto the inclined baffle 101, the gas cylinder 500 slides downward due to the action of gravity, and the ring sleeve 434 and the outer wall of the gas cylinder 500 roll, and the gas cylinder 500 can slide along the inclined baffle 101 without the relevant staff further adjusting the clamping force of the clamping device 400.

[0044] In addition, when loading the empty gas cylinder 500, the relevant staff can clamp the gas cylinder 500 through the clamping device 400, and pull the gas cylinder 500 along the inclined baffle 101 as the pushing device 200 is retracted. At this time, the ring sleeve 434 and the outer wall of the gas cylinder 500 rotate, so that the gas cylinder 500 can move upward synchronously when moving along the inclined baffle 101, further reducing the operation of the relevant staff in carrying the air cylinder 500, which is more convenient.

[0045] In one embodiment of the present invention, Figure 4 As shown, the pushing device 200 includes a second driving motor 210 , a bidirectional lead screw 220 , a lead screw slider 230 and a connecting rod 240 .

[0046] Among them, the bidirectional screw 220 is arranged in the transfer vehicle 100 and connected to the output end of the second drive motor 210. The two screw sliders 230 are respectively arranged at the two ends of the bidirectional screw 220. The two sides of each screw slider 230 are pivotally connected to the two push plates 300 through the connecting rod 240.

[0047] It can be understood that both ends of the connecting rod 240 are respectively connected to the corresponding screw slider 230 and the corresponding push pivot.

[0048] It should be noted that when the pushing device 200 pushes the two push plates 300 to move outward, the relevant staff can turn on the second drive motor 210 to rotate the bidirectional screw 220, so that the two screw sliders 230 move away from each other, so that the connecting rod 240 on the screw slider 230 pushes the corresponding baffle 101 to move outward.

[0049] In one embodiment of the present invention, Figure 4 As shown, the top of the push plate 300 is higher than the height of the body of the transfer vehicle 100 to prevent the clamping arm structure 430 in the clamping device 400 from interfering with the body of the transfer vehicle 100 when it is unfolded.

[0050] A plurality of positioning plates 401 are provided at the lower part of the push plate 300, and the plurality of positioning plates 401 correspond one-to-one to the plurality of clamping devices 400. When the gas cylinder 500 is loaded, the bottom of the gas cylinder 500 is fitted with the positioning plate 401, and the upper part of the gas cylinder 500 is clamped by the clamping device 400, thereby ensuring stability during transportation.

[0051] The transfer vehicle 100 is provided with a handle 102 for easy pushing, and the handle 102 is provided with a control switch, which is electrically connected to the pushing device 200 and the clamping device 400 respectively.

[0052] In addition, a traveling mechanism 103 is provided at the bottom of the transfer vehicle 100 .

[0053] As a possible scenario, the walking mechanism 103 includes a power motor and a driving wheel group. The driving wheel group is driven to rotate by the power motor, so there is no need for relevant staff to push the transfer vehicle 100.

[0054] In one embodiment of the present invention, the bottom of the baffle 101 is pivotally connected to the bottom of the side of the transfer vehicle 100, that is, the baffle 101 is rotationally connected to the bottom of the transfer vehicle 100 through a plurality of hinges.

[0055] The top of the baffle 101 is detachably connected to the top of the transfer vehicle 100 via a latch.

[0056] It is understandable that during transportation, the relevant staff will flip up the baffle 101 and fix it with a latch. When loading and unloading the gas cylinder 500, the latch can be removed and the baffle 101 can be flipped down to contact the ground.

[0057] In summary, according to the high-stability gas cylinder transfer device of the embodiment of the utility model, when transferring gas cylinders, different gas cylinders are clamped respectively by multiple clamping devices 400, which not only reduces the difficulty of operation but also improves the stability of transfer. In addition, through the pushing action of the pushing device 200, after the gas cylinders are filled, the gas cylinders can be pushed to the outside of the transfer vehicle 100 to facilitate unloading of the gas cylinders.
