[0002] As a commonly used pressure vessel for storing compressed gas, the gas cylinder needs to undergo an underwater airtightness test before use to check its airtightness and prevent leakage caused by substandard welding, which would affect the performance of the gas cylinder. During the airtightness test, the entire gas cylinder filled with pressurized gas is immersed in water. The gas cylinder is observed for any bubbling or leakage during the test. If no bubbling or leakage occurs after the gas cylinder has been pressurized for a certain period, the airtightness test is considered passed.

[0003] The patent with authorization announcement number CN222825206U discloses a gas cylinder airtightness testing device, which solves the problem of needing to manually squeeze and soak the gas cylinder during the airtightness testing process, avoids personal injury caused by sudden explosion during the airtightness testing process, and effectively ensures the safety of the airtightness testing of the gas cylinder.

[0004] The existing technical solutions mentioned above have the following drawbacks: Although the patent mentioned above solves the problem of manual squeezing and immersion in liquid during the air tightness test of the air storage cylinder, since the air storage cylinder is placed far from the edge of the water tank, it is necessary to manually lift the air storage cylinder a certain distance to place it. The air storage cylinder is made of metal and has a certain weight, which increases the labor intensity of the personnel. Therefore, a tooling for air tightness testing of air cylinders is proposed.

Example

[0021] Please see Figure 1-5This utility model provides a technical solution: a tooling for testing the air tightness of an air cylinder, including a water tank 1, with two support columns 2 installed on the bottom inner side of the water tank 1, and a fixing frame 3 installed on the top of the two support columns 2, with a lifting component installed on the fixing frame 3.

[0022] By incorporating a lifting assembly, personnel can easily access the gas cylinder, reducing their workload. The lifting assembly includes two fixed shafts 4, two first support rods 5, and two second support rods 6. The two fixed shafts 4 are rotatably connected to a fixed frame 3. The two first support rods 5 are fixedly connected to both ends of one fixed shaft 4, and the two second support rods 6 are fixedly connected to both ends of the other fixed shaft 4. A connecting seat 7 is installed on the inner side of one end of each of the two first support rods 5 and the two second support rods 6. A placement seat 8 is fixedly connected to the bottom side of one side of the connecting seat 7. Two connecting shafts 12 are fixedly connected to the connecting seat 7. One end of each of the two first support rods 5 and the two second support rods 6 is fixedly connected to the two ends of the two connecting shafts 12. The other ends of the two first support rods 5 drive one end of the second support rod 6 to move through the connecting seat 7, so that the two second support rods 6 rotate around another fixed shaft 4. During this process, the connecting seat 7 remains vertical and moves downward, so that the air storage cylinder is submerged in the middle of the water tank 1. A fixing component is installed on the top of the connecting seat 7, and a driving component is provided on the rear side of the fixing frame 3.

[0023] By setting a fixing component, the air cylinder can be quickly fixed. The fixing component includes a connecting frame 9, a first electric push rod 10, and a pressure plate 11. The connecting frame 9 is fixedly connected to the top of the connecting seat 7. The first electric push rod 10 is installed on the top of the connecting frame 9. The pressure plate 11 is fixedly connected to one end of the first electric push rod 10 that passes through the top of the connecting frame 9. The top of the placement seat 8 is provided with a first arc-shaped groove, which is used to limit the placement of the air cylinder. The bottom of the pressure plate 11 is provided with a second arc-shaped groove, and the pressure plate 11 is located directly above the placement seat 8. By placing the air cylinder in the first arc-shaped groove on the top of the placement seat 8, and then controlling the push rod of the first electric push rod 10 to extend through the switch group, the push rod of the first electric push rod 10 drives the pressure plate 11 to move downward and abut against the outside of the air cylinder. The air cylinder abuts against the inside of the second arc-shaped groove, thereby completing the fixing of the air cylinder.

[0024] The movement of the air tank can be accomplished by setting up a drive assembly. The drive assembly includes a mounting base 13, a second electric push rod 14, and a connecting rod 15. The mounting base 13 is fixedly connected to the top rear side of the fixed frame 3. One end of the second electric push rod 14 is hinged to the inside of the mounting base 13. The connecting rod 15 is fixedly connected to the other end of the inner side of the two first support rods 5. A sleeve is movably sleeved on the outer side of the connecting rod 15. The push rod end of the second electric push rod 14 is fixedly connected to the outer side of the sleeve. During the test, the push rod of the second electric push rod 14 pulls the other end of the two first support rods 5 to rotate around a fixed shaft 4. The other end of the two first support rods 5 drives one end of the second support rod 6 to move through the connecting base 7, so that the two second support rods 6 rotate around another fixed shaft 4, so that the air tank is submerged in the middle of the water tank 1. After the test is completed, the push rod of the second electric push rod 14 pushes the other end of the first support rod 5 to move, and drives the air storage cylinder to move out of the water tank 1 through the connecting seat 7. At this time, the connecting seat 7 is located at the edge of the water tank 1, which makes it convenient for personnel to take the air storage cylinder.

[0025] One end of the water tank 1 is connected to a drain pipe 16, and a ball valve 17 is installed on the drain pipe 16. When it is necessary to replace the water in the water tank 1, the water can be discharged outward through the drain pipe 16 by rotating the ball valve 17.

[0026] The working principle or structural principle is as follows: When testing the air storage cylinder, the air storage cylinder is placed in the first arc-shaped groove at the top of the placement seat 8. Then, the push rod of the first electric push rod 10 is extended by controlling the switch group. The push rod of the first electric push rod 10 drives the pressure plate 11 to move downward and abut against the outside of the air storage cylinder. The air storage cylinder abuts against the inside of the second arc-shaped groove, thus completing the fixation of the air storage cylinder. Then, the interface of the air storage cylinder is sealed, leaving a structural connection to the air source. Then, the push rod of the second electric push rod 14 is reset by controlling the switch group. The push rod of the second electric push rod 14 pulls the other end of the two first support rods 5 to rotate around a fixed shaft 4. The other end of the two first support rods 5 drives one end of the second support rod 6 to move through the connecting seat 7, so that the two second support rods 6 rotate around another fixed shaft 4. During this process, the connecting seat 7 remains vertical and moves downward, so that the air storage cylinder is submerged in the middle of the water tank 1. At this time, air is injected into the air storage cylinder through the air source, and the air tightness of the air storage cylinder can be tested.

[0027] After the test is completed, the push rod of the second electric push rod 14 is extended by controlling the switch group. The push rod of the second electric push rod 14 then pushes the other end of the first support rod 5 to move, and drives the air storage cylinder to move out of the water tank 1 through the connecting seat 7. At this time, the connecting seat 7 is located at the edge of the water tank 1, which makes it convenient for personnel to take the air storage cylinder and reduce the labor intensity of personnel.
