[0001] The utility model relates to the technical field of pressure testers, and specifically, to an intelligent pipeline testing pressure tester. Background Art

[0002] An intelligent pipeline testing pressure tester is a device used to test the pressure resistance and toughness of pipelines. Generally, a pressure sensor is used to detect the pressure value borne on the inner side of the pipeline, and then the detected value is displayed through a display, without the need for manual calculation, so as to assist the tester more intuitively and conveniently to obtain the pressure-bearing data of the pipeline for subsequent recording and research.

The liquid in the water tank is exported by electric hydraulic pressure, and the liquid is pressed into the pipeline to be tested for hydraulic testing from the first pressure test discharge port and the second pressure test discharge port.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] As Figures 1-5As shown in the figure, the utility model provides a technical solution: an intelligent pipeline testing pressure tester, which includes a pressure testing frame 1. Inside the pressure testing frame 1, a test pipeline 11 is inserted. One end of the test pipeline 11 is attached to a protective door 12. One end of the protective door 12 is rotatably connected to the pressure testing frame 1. On the upper side of one end of the pressure testing frame 1 near the protective door 12, a water tank 13 is fixedly connected. On one side of the water tank 13, a hose 14 is fixedly connected. The end of the hose 14 away from the water tank 13 penetrates and is fixedly connected inside the protective door 12. In the middle of the upper side of the pressure testing frame 1, a pressure sensor 15 is fixedly connected. Above the pressure sensor 15, a display screen 16 is fixedly connected. On the inner side of one end of the pressure testing frame 1, a protective glass 17 is fixedly connected. On the outer side of the end of the pressure testing frame 1 away from the protective door 12, a power component is fixedly connected. The lower outer side of the power component is engaged with a telescopic component. On the side of the telescopic component away from the power component, a fixed disk 4 is fixedly connected. On the upper end of the side of the fixed disk 4 close to the telescopic component, a limiting component is fixedly connected. Inside the middle end of the fixed disk 4, a linkage component is fixedly connected. The outer end of the linkage component is fixedly connected to an adjusting component. On the outer side of the middle end of the adjusting component, a clamping component is fixedly connected. When conducting a pressure test on the test pipeline 11, first insert one end of the test pipeline 11 inside the clamping component. Then start the linkage component. The linkage component drives the adjusting component to operate. After the adjusting component operates, it drives the clamping component to move. The test pipeline 11 is clamped and fixed by the clamping component. Subsequently, after closing the protective door 12, start the power component. The power component drives the telescopic component to operate. The telescopic component drives the fixed disk 4 and the clamped test pipeline 11 to move with the assistance of the limiting component, making the test pipeline 11 fit with the hose 14 on the protective door 12. Then start the water tank 13, and use the water pump inside the water tank 13 to pump out the water and inject the water into the test pipeline 11 through the hose 14 for pressure testing. The pressure inside the test pipeline 11 is detected by the pressure sensor 15, and the pressure testing value is displayed by the display screen 16. When the pressure tester conducts a pressure test on the test pipeline 11, it can not only clamp and fix test pipelines 11 with different diameters, but also clamp test pipelines 11 with different lengths, making the test range of the pressure tester more comprehensive. It can achieve automatic adjustment and fixation, and thus realize intelligent fixation and detection, improving the use convenience of the pressure tester.

[0023] It should be noted that the model number of the pressure sensor 15 is PTJ204. In addition, a water pump is installed inside the water tank 13. Starting the water tank 13 means starting the water pump inside it, and then using the water pump to pump out the water stored inside the water tank 13.

[0024] Such as Figure 3 and Figure 4As shown in the figure, the power assembly includes a housing 2 fixedly connected to the outer side of one end of the pressure test frame 1 away from the protective door 12. A first motor 21 is fixedly connected to the inner side of the upper end of the housing 2. The output shaft of the first motor 21 is fixedly connected with a first bevel gear 22. A second bevel gear 23 is meshed with the outer side of one end of the first bevel gear 22. When the first motor 21 is started, the output shaft drives the first bevel gear 22 to rotate after the first motor 21 is started. After the first bevel gear 22 rotates, it drives the second bevel gear 23 and the telescopic assembly to operate by meshing with the second bevel gear 23, facilitating power output, so that the telescopic assembly operates.

[0025] As Figure 4 shown in the figure, the telescopic assembly includes an internally threaded tube 3 fixedly connected to the outer side of the middle end of the second bevel gear 23. One end of the internally threaded tube 3 away from the second bevel gear 23 penetrates and is connected in the pressure test frame 1. A first external threaded rod 31 is inserted and meshed inside one end of the internally threaded tube 3 away from the second bevel gear 23. One side of the first external threaded rod 31 away from the internally threaded tube 3 is fixedly connected to a fixed disk 4. After the first bevel gear 22 rotates, it drives the second bevel gear 23 and the internally threaded tube 3 to rotate by meshing with the second bevel gear 23. After the internally threaded tube 3 rotates, through meshing with the first external threaded rod 31, the first external threaded rod 31 drives the fixed disk 4 to move, facilitating the movement adjustment of the position of the fixed disk 4, so that the fixed disk 4 drives the test pipeline 11 to fit with the protective door 12.

[0026] As Figure 4 shown in the figure, the limiting assembly includes a connecting plate 5 fixedly connected to the outer side of the upper end of the fixed disk 4. A slider 51 is fixedly connected to the lower side of one end of the connecting plate 5 away from the fixed disk 4. A chute 52 is arranged on the outer side of the lower end of the slider 51. One side of the chute 52 away from the fixed disk 4 is fixedly connected to the pressure test frame 1. The lower end of the slider 51 is inserted and slides in the chute 52. After the fixed disk 4 moves, it synchronously drives the connecting plate 5 and the test pipeline 11 to move. After the connecting plate 5 moves, it drives the slider 51 to slide in the chute 52, using the sliding of the slider 51 to limit the movement of the fixed disk 4, facilitating the limitation of the movement of the fixed disk 4.

[0027] As Figure 5 shown in the figure, the linkage assembly includes a second motor 6 fixedly connected to the inside of one end of the fixed disk 4. The output shaft of the second motor 6 is fixedly connected with a transmission rod 61. One side of the transmission rod 61 away from the second motor 6 is rotatably connected to the inside of the fixed disk 4. A third bevel gear 62 is fixedly connected to the outer side of one end of the transmission rod 61 close to the second motor 6. A fourth bevel gear 63 is meshed with the outside of the third bevel gear 62. When the second motor 6 is started, the output shaft drives the transmission rod 61 and the third bevel gear 62 to rotate after the second motor 6 is started. After the third bevel gear 62 rotates, it drives the fourth bevel gear 63 and the adjustment assembly to operate by meshing with the fourth bevel gear 63, facilitating the simultaneous operation of three groups of adjustment assemblies.

[0028] As Figure 5 shown, the adjusting assembly includes a second external threaded rod 7 fixedly connected to the side of the fourth bevel gear 63 away from the third bevel gear 62, and the side of the second external threaded rod 7 away from the fourth bevel gear 63 is rotatably connected to the fixed disk 4. An internal threaded plate 71 is engaged with the outer side of the middle end of the second external threaded rod 7. After the second external threaded rod 7 rotates, the engagement with the internal threaded plate 71 causes the internal threaded plate 71 to drive the clamping assembly to move to clamp and fix the test pipeline 11, facilitating the simultaneous driving of the three groups of clamping assemblies to move, so as to clamp and fix the outer side of the test pipeline 11.

[0029] As Figure 5 shown, the clamping assembly includes a clamping plate 8 fixedly connected to the side of the internal threaded plate 71 away from the fixed disk 4, and a rubber pad 81 is fixedly connected to the outer side of the clamping plate 8. The three groups of clamping plates 8 and rubber pads 81 are arranged in an arc shape, which is convenient for better fitting the outer side of the test pipeline 11, and at the same time, the outer side of the test pipeline 11 is protected by the rubber pad 81.

[0030] Working principle: When pressure testing the test pipeline 11, first insert one end of the test pipeline 11 between the three groups of rubber pads 81, and then start the second motor 6. After the second motor 6 starts, the output shaft drives the transmission rod 61 and the third bevel gear 62 to rotate. After the third bevel gear 62 rotates, it drives the fourth bevel gear 63 and the second external threaded rod 7 to rotate through meshing with the fourth bevel gear 63. After the second external threaded rod 7 rotates, it makes the internal threaded plate 71 drive the clamping plate 8 and the rubber pad 81 to move through meshing with the internal threaded plate 71 to clamp and fix the test pipeline 11. Subsequently, close the protective door 12. After the protective door 12 is closed, start the first motor 21. After the first motor 21 starts, the output shaft drives the first bevel gear 22 to rotate. After the first bevel gear 22 rotates, it drives the second bevel gear 23 and the internal threaded pipe 3 to rotate through meshing with the second bevel gear 23. After the internal threaded pipe 3 rotates, through meshing with the first external threaded rod 31, the first external threaded rod 31 drives the fixed disk 4 to move. After the fixed disk 4 moves, it synchronously drives the connecting plate 5 and the test pipeline 11 to move. After the connecting plate 5 moves, it drives the slider 51 to slide in the chute 52, and uses the sliding of the slider 51 to limit the movement of the fixed disk 4. At the same time, after the fixed disk 4 drives the test pipeline 11 to move, the other end of the test pipeline 11 is attached to the hose 14 on the protective door 12. After waiting for the test pipeline 11 to be squeezed and attached to the protective door 12, at this time, close the first motor 21. Subsequently, start the water tank 13, use the water pump inside the water tank 13 to pump out water and inject it into the hose 14, and then use the hose 14 to inject water into the test pipeline 11. Subsequently, use the pressure sensor 15 to measure the pressure value in the test pipeline 11, and the measurement result is displayed through the display screen 16. During the test process, use the pressure test frame 1 and the protective glass 17 to protect the outside of the test pipeline 11 to prevent the water flow from spraying out due to the rupture of the test pipeline 11 during the test. After the test is completed, start the first motor 21 to make its output shaft rotate in the reverse direction, so that the fixed disk 4 drives the test pipeline 11 to return to its original position. Then open the protective door 12, and then start the second motor 6 to make the clamping plate 8 drive the rubber pad 81 to return to its original position. Finally, take out the test pipeline 11 after pressure measurement.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
