Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a tooling for testing the airtightness of acoustic tubes. Background Technology

[0002] Sonic logging tubes are indispensable acoustic testing tubes. They can be used to detect the quality of a pile. Sonic logging tubes are the channels through which the probe enters the interior of the pile when performing ultrasonic testing on cast-in-place piles. They are an important component of the ultrasonic testing system for cast-in-place piles. The way they are embedded in the pile and their arrangement on the cross-section of the pile will directly affect the test results.

[0003] Chinese utility model patent, authorized publication number "CN219776995U", discloses an airtightness testing fixture for processing sonic logging pipes. Specifically, the fixture includes a support assembly with two mounting seats at the top center and a control rod on one side of each mounting seat. This improved airtightness testing fixture, through the cooperation of a water pump, water pipe, and rubber block, enables water injection airtightness testing of the sonic logging pipe during production. This allows workers to quickly assess the airtightness of the pipe during testing, significantly increasing testing efficiency. Furthermore, the fixture utilizes a limiting plate, control rod, and threaded block to fix the pipe according to its length during production, greatly increasing stability during testing. This eliminates the need for manual fixing of the pipe, significantly reducing labor intensity and meeting the airtightness testing requirements for sonic logging pipes.

[0004] In the above-mentioned technical solution, when using water vapor to test the airtightness of the sonic logging tube, the water vapor can easily cause corrosion inside the sonic logging tube. An additional process is required to dry the inside of the sonic logging tube after the test. Furthermore, since there may be impurities such as dust and iron filings inside the production tube, the test gas can be directly discharged, affecting the surrounding processing environment and making it inconvenient for the test personnel to carry out subsequent operations. Therefore, we propose an airtightness testing fixture for processing sonic logging tubes. Utility Model Content

[0027] Please see Figure 1-4 This utility model provides a technical solution: a tooling for testing the airtightness of acoustic tubes, comprising:

[0028] Test bench 1, the top of test bench 1 is provided with a sliding groove 12;

[0029] The test component is located on test bench 1.

[0030] The test assembly includes a first threaded rod 11, a drive motor 10, a sliding block 16, and a mounting plate 2. The first threaded rod 11 is rotatably connected to the inside of the sliding groove 12. The drive motor 10 is fixedly mounted on one side of the test bench 1. The output end of the drive motor 10 extends rotatably into the inside of the sliding groove 12 and is fixedly connected to the first threaded rod 11. The sliding block 16 is threaded onto the outer surface of the first threaded rod 11 and is slidably connected to the inside of the sliding groove 12. The mounting plate 2 is fixedly connected to the top of the sliding block 16. The top of the test bench 1 is fixedly connected to the same mounting plate 2. Mounting shells 5 are fixedly connected to the opposite sides of the two mounting plates 2. Sealing covers 6 are fixedly connected to the inside of the two mounting shells 5.

[0031] The test assembly also includes a filter box 7, a filter plate 17, a rotary motor 15, a second threaded rod 20, and a limiting rod 18. The filter box 7 is fixedly connected to the top of the test bench 1. The filter plate 17 is slidably connected inside the filter box 7. The second threaded rod 20 and the limiting rod 18 are both rotatably connected inside the filter box 7. The rotary motor 15 is fixedly installed on one side of the filter box 7. The output end of the rotary motor 15 extends into the interior of the filter box 7 and is fixedly connected to the second threaded rod 20. A cleaning brush 19 is threaded onto the outer surface of the second threaded rod 20. The bottom end of the cleaning brush 19 is slidably fitted onto the outer surface of the limiting rod 18.

An exhaust fan 3 is fixedly installed on the top of the test bench 1. An air supply pipe 8 is fixedly connected to the exhaust end of the exhaust fan 3. The end of the air supply pipe 8 away from the exhaust fan 3 extends into the sealing cover 6 away from the drive motor 10. The same control valve 4 is fixedly installed on the air supply pipe 8.

[0033] A collection box 14 is slidably connected inside the filter box 7, and a sealing gasket is provided at the sliding connection between the collection box 14 and the filter box 7.

[0034] Furthermore, when using the device, the drive motor 10 is started by connecting an external power source. The drive motor 10 will drive the first threaded rod 11 to rotate. The rotation of the first threaded rod 11 will drive the sliding block 16 to move horizontally under the guidance of the sliding groove 12. The movement of the sliding block 16 will drive the mounting plate 2 on it to move, so that the two ends of the sonic logging tube can be installed inside the two sealing covers 6 respectively. Then, the sliding block 16 will drive the mounting plate 2 on it to move closer to the exhaust fan 3, so that the two ends of the sonic logging tube can fit tightly with the inside of the corresponding sealing cover 6.

[0035] Furthermore, when using the device, the operator opens the control valve 4 on the air supply pipe 8 and closes the control valve 4 on the exhaust hose 9, thereby starting the exhaust fan 3 by connecting an external power source. The exhaust fan 3 will draw external air into the sonic logging tube. The filter on the exhaust fan 3 can filter dust from the air. The pressure inside the sonic logging tube is judged by observing the pressure gauge 13. When the pressure is sufficient, the control valve 4 on the air supply pipe 8 and the exhaust fan 3 are closed sequentially. After waiting for a period of time, the pressure gauge 13 is observed to test the airtightness inside the sonic logging tube. When the test of the inside of the sonic logging tube is completed... Then, the control valve 4 on the exhaust hose 9 is opened, so that the air pressure in the sonic logging tube can be discharged into the filter box 7 through the exhaust hose 9, so that the filter plate 17 can filter the gas entering the filter box 7, thereby facilitating the filtration of dust and impurities in the gas before discharge. By connecting an external power source to start the rotating motor 15, the rotating motor 15 will drive the second threaded rod 20 to rotate. The rotation of the second threaded rod 20 will drive the cleaning brush 19 to move horizontally under the guidance of the limit rod 18, thereby facilitating the cleaning of the surface of the filter plate 17, so that the cleaned dust can be discharged into the collection box 14.

[0036] With the cooperation of the housing 5, sealing cover 6, filter box 7, filter plate 17, second threaded rod 20, limiting rod 18 and cleaning brush 19, it is convenient to use air to test the airtightness of the inside of the acoustic tube, avoiding contact with moisture.
