Description

Technical Field

[0001] This application relates to the field of inflation equipment, and more particularly to an inflation device for gas cylinders. Background Technology

[0002] A gas cylinder is a pressure-resistant container used for storing and transporting compressed gases, liquefied gases, or dissolved gases, and is widely used in industry, medical fields, scientific research, and other areas. A gas cylinder filling device is a device used to fill gas cylinders. The operator only needs to place the gas cylinder in the filling position and start the device, and the filling device will automatically fill the cylinder according to the set parameters such as pressure, time, and gas flow rate.

[0003] In the prior art, when filling gas cylinders, the filling device can usually fill a single gas cylinder or multiple parallel gas cylinders. However, after filling, the filled gas cylinder needs to be moved to make room for the new gas cylinder. This affects the filling efficiency of the gas cylinder and the practicality of the device. Utility Model Content

[0004] In order to improve the filling efficiency of gas cylinders, this application provides a gas cylinder filling device.

[0005] The gas cylinder filling device provided in this application adopts the following technical solution:

[0006] A gas cylinder filling device includes a fixed frame, multiple positioning rods fixedly installed on the upper end of the fixed frame, a gas supply pipe installed on the upper side of the positioning rods, and multiple filling valves fixedly connected to the gas supply pipe. Each filling valve includes a valve body, a connecting pipe, and a filling head. The air inlet of the valve body is fixedly connected to the gas supply pipe, the upper end of the connecting pipe is fixedly connected to the air outlet of the valve body, the filling head is fixedly connected to the lower end of the connecting pipe, and multiple workbenches fixedly connected to the fixed frame are fixedly connected to the lower side of the filling head.

[0007] By adopting the above technical solution, firstly, by setting multiple positioning rods and multiple inflation valves, multiple gas cylinders can be inflated simultaneously, improving inflation efficiency; secondly, workers can place the gas cylinder rack or gas cylinders between two workbenches, and then walk on the workbenches to connect multiple inflation heads to the gas cylinders one by one, thereby facilitating the inflation operation of the gas cylinders, reducing the steps of manually moving the gas cylinders, and improving the practicality of the device.

[0008] Optionally, the lower end of the positioning rod is threaded with multiple fasteners, and one end of each fastener is threadedly connected to the inner wall of the fixing frame.

[0009] By adopting the above technical solution, not only can the stability of the connection between the positioning rod and the fixed frame be ensured, but the positioning rod can also be quickly installed and disassembled, thereby facilitating the maintenance and adjustment of the device and improving its practicality.

[0010] Optionally, the upper surface of the positioning rod is fixedly connected with a plurality of retaining rings for fixing the gas supply pipe.

[0011] By adopting the above technical solution, it is possible to prevent the air supply pipe from shifting or shaking due to factors such as air pressure during the inflation process, ensuring the stability of the connection between the air supply pipe and the inflation valve, thereby improving the reliability and safety of inflation.

[0012] Optionally, each of the positioning rods is fixedly connected to a plurality of hooks on the side opposite to the inflation valve, and the plurality of hooks are used to hook a plurality of connecting pipes.

[0013] By adopting the above technical solution, the connecting pipe can be hung on the hook, reducing the drooping or swinging of the connecting pipe due to its own weight or external force, thereby ensuring the tightness of the connection between the connecting pipe and the inflation valve, preventing gas leakage, and thus improving the service life of the structure.

[0014] Optionally, a connecting rope is fixedly connected to one end of the positioning rod, and multiple fixing rings are fixedly connected to the outer wall of the connecting rope. Both ends of the connecting tube are fixedly connected to connectors that are fixedly connected to two of the fixing rings, and the other fixing ring is fixedly connected to the middle of the connecting tube.

[0015] By adopting the above technical solution, the connecting rope can improve the protection of the connecting tube, prevent the connecting tube from breaking when the gas cylinder tilts during refilling, and the connecting rope can also move accordingly as the connecting tube bends and deforms, ensuring the smooth progress of the inflation process and improving the overall stability and service life of the structure.

[0016] Optionally, one of the connectors is threaded to the outer wall of the air outlet of the valve body, and the other connector is threaded to one end of the inflation head.

[0017] By adopting the above technical solution, the stability and sealing of the connection between the connecting pipe and the inflation valve and inflation head can be ensured, and the connecting pipe can be easily installed and disassembled. It is also easy to replace and maintain each component individually, which can improve the maintainability and service life of the device.

[0018] Optionally, a railing is fixedly connected to the upper end of the workbench, and one end of the railing is fixedly connected to the side wall of the fixing frame.

[0019] By adopting the above technical solution, the railing can protect the staff or objects on the workbench and prevent the gas cylinder from tipping over to the workbench during the inflation process, thereby improving the safety of the inflation operation.

[0020] Optionally, a limiting rod for limiting multiple inflation heads is fixedly connected to the upper end of the railing.

[0021] By adopting the above technical solution, it is possible to prevent multiple inflation heads from shaking, thereby preventing collisions between the storage rack or gas cylinder and the inflation head when the gas cylinder is placed between two workbenches. This reduces the likelihood of the connecting pipe breaking due to external forces, thus improving the stability and safety of the device.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. This application can not only fill multiple gas cylinders at the same time, but also reduce the steps of moving gas cylinders, improve filling efficiency and device practicality.

[0024] 2. This application uses a limiting rod and hook to prevent the connecting tube and inflation head from shaking, reduce collisions and avoid the connecting tube from breaking due to external force, thereby improving the stability and safety of the device. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a gas cylinder filling device.

[0032] Reference Figure 1The gas cylinder filling device includes a fixing frame 1, multiple positioning rods 2 fixedly installed on the upper end of the fixing frame 1, gas supply pipes 3 fixedly installed on the upper sides of two positioning rods 2, and multiple filling valves 4 fixedly connected to the gas supply pipes 3. In this application, the fixing frame 1 is a concrete wall. In other embodiments, the fixing frame 1 can also be a metal frame, a wall made of stacked bricks, etc. The lower end of the positioning rods 2 is threaded with multiple fasteners 21 that are threaded to the fixing frame 1. The fasteners 21 are fastening bolts, used to ensure the stability of the connection between the positioning rods 2 and the fixing frame 1. The gas supply pipe 3 consists of a main pipe and two branch pipes. Each branch pipe is installed on the upper surface of one positioning rod 2, and one end of the two branch pipes is closed, while the other end is fixedly connected to and communicates with the main pipe to ensure gas flow and prevent gas leakage. The multiple filling valves 4 are fixedly connected to the branch pipes to ensure the stability of the structure. In use, firstly, the gas is guided through the main pipe to the two branch pipes via the gas storage mechanism; then, the filling valve 4 is connected to the gas cylinder to be filled, and the valve is opened until the gas cylinder is filled; finally, the valve is closed, and the above operation is repeated to fill different empty cylinders.

[0033] refer to Figure 1 , Figure 2 The fixed frame 1 has multiple workbenches 5 for people to walk on fixedly connected to one side. Space is reserved between each pair of workbenches 5 for placing gas cylinders or shelves containing gas cylinders. A railing 6 is fixedly connected to the upper end of each workbench 5. The railing 6 is used to reduce the possibility of gas cylinders tipping over, prevent collisions with workers, and improve structural safety. A limiting rod 7 is fixedly connected to the upper side of each railing 6 to restrict the inflation valve 4. The limiting rod 7 is used to hook the lower end of the inflation valve 4, preventing it from swinging and preventing contact between the inflation valve 4 and the gas cylinders or shelves containing gas cylinders, thereby improving the service life of the structure.

[0034] refer to Figure 2 , Figure 3 and Figure 4 Each inflation valve 4 consists of a valve body 41, a connecting pipe 42, and an inflation head 43. The valve body 41 is fixedly connected to the gas supply pipe 3, and a knob is installed at its other end. Rotating the knob opens and closes the valve. An air outlet is fixedly connected to the lower end of the valve body 41. Connectors 421 are fixedly connected to both ends of the connecting pipe 42. One end of one connector 421 has its inner wall threaded to the outer wall of the air outlet to ensure a stable connection between the connecting pipe 42 and the valve body 41. The other end of the connecting pipe 42 has its inner wall threaded to one end of the inflation head 43 to improve the installation efficiency of the inflation head 43 and ensure inflation stability. A rotating part is rotatably connected to the end of the inflation head 43 away from the connector 421. The rotating part improves the ease of connecting the inflation head 43 to the gas cylinder.

[0035] When using it, first align the inflation head 43 with the inflation port of the gas cylinder. Then, rotate the rotating part until the inflation head 43 is fully connected to the inflation port of the gas cylinder. Then, turn the knob to open the valve. The gas is guided from the gas supply pipe 3 to the valve body 41 and the connecting pipe 42, and finally the gas is filled into the gas cylinder through the inflation head 43, thus completing the filling of the gas cylinder.

[0036] refer to Figure 2 , Figure 3 Each positioning rod 2 has multiple connecting ropes 24 fixedly connected to one side. In this application, the connecting ropes 24 are stainless steel ropes; in other embodiments, the connecting ropes 24 can also be ropes made of various metals. Multiple fixing rings 241 are fixedly connected to the outer side of the connecting ropes 24. Each fixing ring 241 consists of two rings, one large and one small, joined together. The smaller ring is fitted around the outside of the connecting rope 24. Two of the larger rings are fixedly connected to the connectors 421 of the connecting tube 42, and the other is fixedly connected to the outer wall of the connecting tube 42, used to fix the connecting ropes 24 to one side of the inflation valve 4. The connecting ropes 24 are used to prevent the connecting tube 42 from breaking under external force, thus improving the service life of the connecting tube 42. Each positioning rod 2 has multiple hooks 23 fixedly connected to the side facing away from the connecting ropes 24. The hooks 23 are used by workers to hang the connecting tube 42, ensuring that the inflation head 43 is higher than the gas cylinder, preventing collisions between the gas cylinder and the inflation head 43 when placing the gas cylinder. The upper side of the positioning rod 2 is fixedly connected with multiple retaining rings 22 for fixing the gas supply pipe 3. The retaining rings 22 are used to ensure the stability of the gas supply pipe 3 and prevent the gas supply pipe 3 from being misaligned.

[0037] The implementation principle of the gas cylinder filling device in this application embodiment is as follows: In use, firstly, a trolley is used to neatly place the gas cylinders between two workbenches 5, or a forklift is used to lift the shelf containing the gas cylinders and place it between the two workbenches 5. Then, the operator stands on the workbench 5 and operates multiple filling heads 43 installed at the gas cylinder's inlet. At this time, by rotating the knob of the valve body 41, gas is passed through the valve body 41, connecting pipe 42, and filling heads 43 to fill the gas cylinder. After the gas cylinder is fully filled, the valve body is tightened. Turn the knob on 41 to remove the inflation head 43, then install it on the air inlet of the remaining gas cylinders. Repeat the above operation until all gas cylinders are filled. Finally, when the gas cylinder is at a low or medium height, you can choose to hang the connecting pipe 42 on the hook 23 to prevent the inflation head 43 from contacting the gas cylinder. When the gas cylinder is too high, you can choose to hook the inflation head 43 on the limit rod 7 to prevent the inflation head 43 from contacting the gas cylinder. This allows you to safely remove the filled gas cylinder and replace it. Repeat the above operation to continue filling the gas cylinder group.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
