Description

Technical Field

[0001] This utility model relates to the field of steel cylinder processing technology, specifically a pressure measuring device for steel cylinder processing. Background Technology

[0002] Pressure testing is a crucial step in the manufacturing process of steel cylinders, ensuring product quality and safety. Traditional methods for testing cylinder pressure typically involve manual operation, placing each cylinder individually into a testing device, pressurizing it with an external air source, and then checking its sealing and pressure resistance. However, this method has the following drawbacks:

[0003] Traditional pressure testing devices lack automated control, making it impossible to automatically position and pressurize gas cylinders. This increases the workload of operators. Furthermore, due to human factors, parameters such as test pressure and holding time may vary for different gas cylinders, leading to inaccurate test results. Utility Model Content

[0031] This utility model provides a pressure measuring device for steel cylinder processing, see reference. Figure 1-3 It includes a water tank 100, a lifting assembly 200, and a pressure supply assembly 300;

[0032] Please continue reading. Figure 1-3 The water tank 100, which serves as the pressure measuring chamber, has connecting brackets 110 on both the left and right sides via connecting bolts. A guide rod 111 is connected to the right connecting bracket 110.

[0033] Please continue reading. Figure 1-3 The lifting assembly 200 is connected to two sets of connecting frames 110, including a motor 210 threadedly connected to the top of the left connecting frame 110, and a connecting plate 220 slidably connected to the two sets of connecting frames 110. The output end of the motor 210 is connected to a threaded rod 211, which extends into the connecting frame 110.

[0034] The left end of the connecting plate 220 is provided with a threaded hole 221 that is screwed into the threaded rod 211, and the right end of the connecting plate 220 is provided with a guide hole 222 that is slidably engaged with the guide rod 111 (the guide hole and the guide rod are slidably engaged to guide and limit the connecting plate, so that the connecting plate can move up and down along the two sets of connecting frames when the threaded rod rotates, referring to the threaded feed action structure). The outer side of the connecting plate 220 is connected to the bracket 223, and the bottom end of the bracket 223 is connected to the placement frame 230.

[0035] The placement rack 230 has multiple placement slots 231, which are arranged linearly and equidistantly from left to right along the outer side of the placement rack 230. The placement rack 230 also has multiple through holes 232, which are arranged on the outer side of the placement slots 231.

[0036] action:

[0037] When the motor 220 is working, it drives the threaded rod 211 to rotate within the connecting frame 110, causing the connecting plate 220 to move up and down between the two sets of connecting frames 110, thereby driving the steel cylinder placed on the placement slot 231 to sink into the water tank 100 for pressure testing.

[0038] Please continue reading. Figure 1-3 The pressure supply component 300 is placed on the connecting plate 220 to perform gas filling and pressure testing operations on the gas cylinder;

[0039] The pressure supply assembly 300 includes multiple sets of telescopic cylinders 310 connected to the top of the connecting plate 220. The telescopic ends of the telescopic cylinders 310 extend to the bottom of the connecting plate 220. The telescopic ends of the telescopic cylinders 310 are connected to inflation heads 311. Multiple sets of inflation heads 311 are arranged one-to-one with the placement slots 231, and branch pipes 321 are connected to the inflation heads 311. Multiple sets of branch pipes 321 are all connected to the main pipe 320. The main pipe 320 is connected to the external air supply end. The inflation heads 311 are driven to move down and dock with the gas cylinder by the telescopic cylinders 310. The gas cylinder is filled by the main pipe 320 and the external air supply end.

[0040] Working principle: When this utility model is in use, the motor 220 drives the threaded rod 211 to rotate within the connecting frame 110, causing the connecting plate 220 to move up and down between the two sets of connecting frames 110, thereby driving the steel cylinder placed on the placement slot 231 to sink into the water tank 100 for pressure testing. The telescopic cylinder 310 drives the inflation head 311 to move down and connect with the steel cylinder, and the main pipe 320 cooperates with the external air supply end to inflate the steel cylinder.
