Description

Technical Field

[0001] The utility model relates to a testing device, in particular to a liner pipe pressure testing device. Background Art

[0002] During the production of liner pipes, a series of physical performance tests are required. Among these, compressive strength testing is a key test item. To ensure the quality of liner pipes, compressive strength testing is typically performed using a pressure testing machine. A common method is to perform a hydraulic test using water as the test medium.

[0003] During a hydrostatic test, testers inject water into the pipe and gradually increase the pressure until the predetermined test pressure is reached. This pressure is then maintained for a specified period to inspect the liner for leaks or structural damage. However, if the liner ruptures during the test, the water inside can quickly splash out. Without dedicated drainage structures, this not only poses a safety hazard to the equipment but also creates a chaotic mess in the test area. Furthermore, debris from the rupture remains within the test apparatus, making cleanup a tedious and time-consuming task.

[0004] Based on this, in order to solve the above-mentioned technical defects, a liner pipe pressure testing device is proposed. Utility Model Content

The control panel 2 is installed on the front side of the pressure testing machine 1 by bolts, and the front side of the pressure testing machine 1 is rotatably connected to the protective frame 4. The protective frame 4 is provided with explosion-proof glass, which is convenient for viewing the internal working conditions of the pressure testing machine 1. The first motor 3 is installed on the left side of the top of the pressure testing machine 1 by bolts, and the output shaft of the first motor 3 is connected to the protective frame 4. The first fixing component 5 is installed on the left side of the pressure testing machine 1, and an external pressure pump is installed on the left side of the pressure testing machine 1. The pressure pump is connected to the first fixing component 5. The second fixing component 6 is slidably connected to the rear side of the pressure testing machine 1, and the second fixing component 6 is aligned with the first fixing component 5. The first motor 3 and the pressure pump are both electrically connected to the control panel 2. A leaking plate 7 for assisting the rapid discharge of water is connected to the lower side of the pressure testing machine 1. A drain pipe 15 is connected to the right side of the lower part of the pressure testing machine 1, and the drain pipe 15 is communicated with the leaking plate 7. A cleaning component is provided on the pressure testing machine 1.

[0023] like Figure 3 As shown, the cleaning assembly includes a second motor 10, a rotating frame 11, a connecting block 12 and a cleaning block 13. The second motor 10 is installed on the right side of the rear of the pressure testing machine 1 by bolts, and the rotating frame 11 is connected to the output shaft of the second motor 10. The left end of the rotating frame 11 is connected to the connecting block 12. A cleaning block 13 for cleaning debris is slidably connected to the position above the leakage plate 7 in the pressure testing machine 1, and the cleaning block 13 is slidably connected to the connecting block 12.

[0024] like Figure 2-Figure 4As shown, it also includes a support frame 8, a collection frame 9 and a guide plate 14. The support frame 8 is connected to the front side of the pressure testing machine 1. A collection frame 9 for collecting debris is placed on the support frame 8. The height of the collection frame 9 is consistent with the height of the leakage plate 7. The lower side of the leakage plate 7 is connected to a guide plate 14 inclined toward the drain pipe 15.

[0025] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, it also includes a connecting frame 16, a filter screen 17 and a card plate 18. The right end of the drain pipe 15 is connected to the connecting frame 16. The filter screen 17 for filtering debris in the water is connected inside the connecting frame 16. The card plate 18 is slidably connected to the right side of the connecting frame 16.

[0026] When conducting a pressure test on the inner liner pipe, the operation control panel 2 starts the first motor 3, and the output shaft of the first motor 3 rotates to drive the protective frame 4 to rotate and open, and then the two ends of the inner liner pipe are connected to the first fixing component 5 and the second fixing component 6 through the connector, and the second fixing component 6 seals the right end of the inner liner pipe, and the first fixing component 5 connects the left end of the inner liner pipe to the pressure pump. After fixing, the first motor 3 is controlled to run in the reverse direction to drive the protective frame 4 to reverse and close, and then the external water pipe can be connected to the pressure pump, and the pressure of the pressure pump can be adjusted by operating the control panel 2, and water is injected into the inner liner pipe through the pressure pump, and the pressure is gradually increased until the predetermined test pressure value is reached, and then the pressure is maintained for a certain period of time. By checking the explosion-proof glass, the test status of the inner liner pipe can be known to check whether there is leakage or structural damage. If the inner liner pipe fails the pressure test and ruptures, the water inside it will splash onto the leaking plate 7. When the pressure pump is turned off, some fragments produced by the rupture will also fall onto the leaking plate 7, and the guide plate 1 4 can make these waters quickly drain into the connection frame 16 through the drain pipe 15, and then be discharged from the connection frame 16. Some small debris will enter the inside of the leaking plate 7, and the filter screen 17 can filter the water to prevent the debris from clogging the connection frame 16. Pull the card plate 18 upward to open it, and the filter screen 17 can be cleaned. Open the protective frame 4 and remove the tested liner pipe. According to the above operation, perform water pressure test on the remaining liner pipes. If there are more debris remaining on the surface of the leaking plate 7, the second motor 10 can be started. The output shaft of the second motor 10 rotates to drive the rotating frame 11 to rotate, so that the rotating frame 11 pushes the cleaning block 13 to move forward through the connecting block 12. The cleaning block 13 will push the debris remaining on the surface of the leaking plate 7 forward to the collecting frame 9. After cleaning is completed, the second motor 10 is controlled to run in the reverse direction to drive the rotating frame 11 to reverse, and the cleaning block 13 can be pulled to move backward and reset through the connecting block 12. Then the second motor 10 is turned off, and the cleaning of the leaking plate 7 is completed.
