Description

Technical Field

[0001] This utility model relates to the field of gas production technology, and in particular to an anti-tipping device for filling industrial gas cylinders. Background Technology

[0002] Industrial gas cylinders are containers used in industrial production for storing and transporting compressed or liquefied gases. They are widely used in many industries, including chemical, machinery, and construction. Gas cylinders should be placed upright and properly secured to prevent tipping. Horizontal placement will cause the cylinder valve to be soaked in liquid gas. When the valve is opened, the liquid gas will rapidly vaporize, causing a sharp increase in pressure inside the cylinder and leading to danger. Therefore, industrial gas cylinders are required for the transportation of gases.

[0003] Currently, industrial gas cylinders are prone to tipping over during inflation due to their instability. The current solution is to secure them before inflation, using a fixing device to hold the cylinders in place. However, different types and sizes of industrial gas cylinders vary in size and shape, and the fixing device cannot fit all cylinders well. This results in some cylinders not being securely fixed in the device, affecting the inflation process and reducing inflation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-tipping device for filling industrial gas cylinders, aiming to improve the problem that the existing technology cannot be well adapted to all gas cylinders, resulting in some gas cylinders not being securely fixed in the device, which in turn affects the filling operation and reduces the filling efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-tipping device for filling industrial gas cylinders, comprising a base platform, with fixed plates fixedly connected to the left and right ends of the front side of the top wall of the base platform, and electric telescopic rods rotatably connected to the left and right ends of the rear side of the fixed plates.

A rotating shaft is rotatably connected to the left end of the front side of the clamping plate, and the front side of the rotating shaft is rotatably connected to the middle of the front side of the fixed plate. A fixed shell is fixedly connected to the rear side of the top wall of the base platform, and a vertical shell is fixedly connected to the left side of the top wall of the base platform. A cylinder is fixedly connected to the right side of the vertical shell, and a lifting plate is fixedly connected to the right end of the cylinder. A limiting shell is fixedly connected to the right side of the top wall of the base platform. The inner right end of the lifting plate is slidably connected to the inner part of the limiting shell. A sealing mechanism is provided in the middle of the top wall of the lifting plate, and the sealing mechanism is used to improve the sealing performance of the top of the gas cylinder.

[0007] The sealing mechanism includes an extraction fan, the bottom wall of which is fixedly connected to the middle of the top wall of the lifting plate. Extraction pipes are connected to the left and right sides of the front end of the extraction fan. An electromagnetic regulating valve is fixedly installed in the middle of the extraction pipe. A sealing sleeve is connected to the end of the electromagnetic regulating valve. Electric push rods are fixedly connected to the left and right sides of the top wall of the lifting plate. A conveying pipe is fixedly connected to the top of the electric push rod. The bottom of the outer wall of the conveying pipe is fixedly connected to the top of the inner wall of the sealing sleeve.

[0008] As a further description of the above technical solution:

[0009] The sealing mechanism also includes two sealing rings, which are respectively fixedly installed on one end of the outer wall of the corresponding extraction tube, and the outer wall of the sealing ring is fixedly connected to one side of the sealing sleeve.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, an industrial gas cylinder is placed on the inner wall of a fixed shell, thereby activating an electric telescopic rod. This causes the rotating column and clamping plate to move synchronously.

Thus, when the extraction fan is started, the air inside the sealing sleeve is extracted, and the flow rate is adjusted by the electromagnetic regulating valve, thereby sealing the top end of the gas cylinder and the bottom end of the delivery pipe and reducing leakage during filling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an anti-tipping device for filling industrial gas cylinders, comprising a base 1. Fixed plates 3 are fixedly connected to the left and right ends of the front side of the top wall of the base 1, connecting to an electric telescopic rod 4. The electric telescopic rod 4 is rotatably connected to the left and right ends of the rear side of the fixed plate 3. Driven by the electric telescopic rod 4, a rotating column 5 and a clamping plate 6 are displaced. A rotating column 5 is rotatably connected to the rear end of the electric telescopic rod 4, and a clamping plate 6 is rotatably connected to the rear side of the rotating column 5. A rotating shaft 7 is rotatably connected to the left front end of the clamping plate 6. While the rotating shaft 7 restricts the displacement of the clamping plate 6, the clamping plate 6 rotates around the rotating shaft 7, thereby clamping the industrial gas cylinder. The front side of the rotating shaft 7 is rotatably connected to the middle of the front side of the fixed plate 3. A fixed shell 8 is fixedly connected to the rear side of the top wall of the base 1, cooperating with the fixed shell 8 to complete the anti-tipping work of the gas cylinder. The left side of the top wall of the base 1 is fixed... A vertical shell 10 is fixedly connected to the base platform 1. A cylinder 11 is fixedly connected to the right side of the vertical shell 10. Driven by the cylinder 11, the lifting plate 13 is raised and lowered under the restriction of the limiting shell 12 to adapt to gas cylinders of different heights. The lifting plate 13 is fixedly connected to the right end of the cylinder 11. The limiting shell 12 is fixedly connected to the right side of the top wall of the base platform 1. The inner right end of the lifting plate 13 is slidably connected to the inner end of the limiting shell 12. A sealing mechanism 2 is provided in the middle of the top wall of the lifting plate 13 to improve the sealing performance of the top of the gas cylinder. Two connecting seats 16 are fixedly connected to the left and right sides of the base platform 1. Support columns 17 are fixedly connected inside the multiple connecting seats 16. The stability of the device is improved through the connecting seats 16 and the support columns 17. The outer walls of the two fixed plates 3 are both designed with a smooth surface. The two fixed plates 3 are both designed with a symmetrical surface. The smooth surface of the top of the fixed plates 3 is used to improve the pressure resistance.

[0032] Reference Figure 1 , Figure 3 and Figure 5The sealing mechanism 2 includes an extraction fan 201. The bottom wall of the extraction fan 201 is fixedly connected to the middle of the top wall of the lifting plate 13. Extraction pipes 202 are connected to the left and right sides of the front end of the extraction fan 201, connecting to the sealing sleeve 204. An electromagnetic regulating valve 203 is fixedly installed in the middle of the extraction pipe 202, and the end of the electromagnetic regulating valve 203 is connected to the sealing sleeve 204. This allows air inside the sealing sleeve 204 to be extracted when the extraction fan 201 is activated, thereby improving the sealing effect between the top of the gas cylinder and the bottom of the delivery pipe 206. The left and right sides of the top wall of the lifting plate 13... Electric push rods 205 are fixedly connected to both sides. By activating the electric push rods 205, the middle part of the delivery pipe 206 can be adjusted. The top of the electric push rod 205 is fixedly connected to the delivery pipe 206, and the bottom of the outer wall of the delivery pipe 206 is fixedly connected to the top of the inner wall of the sealing sleeve 204. The sealing mechanism 2 also includes two sealing rings 207. The two sealing rings 207 are respectively fixedly installed on one end of the outer wall of the corresponding extraction pipe 202, so that the sealing rings 207 improve the connection sealing of one end of the extraction pipe 202. The outer wall of the sealing ring 207 is fixedly connected to one side of the sealing sleeve 204.

[0033] Reference Figure 1 , Figure 3 and Figure 4 A control switch 14 is fixedly connected to the front side of the upright shell 10. The control switch 14 is electrically connected to the electric telescopic rod 4, the cylinder 11, the extraction fan 201, and the electric push rod 205. The control switch 14, which is electrically connected to the electric telescopic rod 4, the cylinder 11, the extraction fan 201, and the electric push rod 205, enables the control switch 14 to open and close the equipment. Rubber pads 9 are fixedly connected to the left and right ends of the front side of the fixed shell 8. Both rubber pads 9 adopt an arc design. The rubber pads 9 reduce the damage to the gas cylinder on one side of the fixed shell 8. Multiple arc grooves 15 are opened on one side of the multiple clamping plates 6. The multiple arc grooves 15 improve the toughness of the clamping plates 6. The multiple arc grooves 15 are opened at equal intervals.

[0034] Working principle: When in use, the industrial gas cylinder is placed on the inner front wall of the fixed shell 8, thereby activating the electric telescopic rod 4, causing the rotating column 5 and the clamping plate 6 to move synchronously. Then, under the restriction of the displacement of the rotating shaft 7, the clamping plate 6 rotates around the rotating shaft 7 as the axis driven by the electric telescopic rod 4. Thus, the two clamping plates 6 on the back side of a single fixed plate 3 clamp inward, thereby achieving the effect of fixing the industrial gas cylinder and completing the anti-tipping work. At the same time, the opening and closing angle of the two clamping plates 6 can achieve the purpose of fixing gas cylinders of different specifications and types, improving the applicability. In addition, the lifting plate 13 can adapt to different gas cylinder heights, avoiding instability of industrial gas cylinders during filling.

[0035] Furthermore, the bottom end of the sealing sleeve 204 is engaged with the top end of the air pipe, and the bottom end of the delivery pipe 206 is installed and connected to the bottom end of the gas cylinder inside the sealing sleeve 204. This allows the air inside the sealing sleeve 204 to be drawn out and deformed by the extraction pipe 202 when the extraction fan 201 is started, thus fitting the connection between the gas cylinder and the delivery pipe 206. At the same time, the airflow rate is adjusted by the electromagnetic regulating valve 203, achieving a sealing effect between the top end of the gas cylinder and the bottom end of the delivery pipe 206, thereby reducing leakage during inflation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
