Description
Technical Field
[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a pipeline pressure testing support device. Background Technology
[0002] In various pipeline projects, such as long-distance water pipelines, gas pipelines, and heating pipelines, pressure tests are required to ensure the safe and stable operation of the pipeline system under normal working pressure and abnormal conditions. This is to check whether the pipeline's sealing performance, strength, and other properties meet the design requirements and to ensure that there will be no water or gas leaks after the pipeline is put into use. At present, most pipeline fixing methods use clamps or clamps, which rely heavily on bolt fixing. If the tightening force is uneven, it can easily lead to pipeline loosening or excessive local stress, affecting the pressure test results. Therefore, based on the above problems, this utility model provides a pipeline pressure testing support device to meet the requirements. Utility Model Content

[0026] like Figures 1 to 6 As shown, an embodiment of this utility model provides a pipeline pressure testing and support device, including a base frame 1, a first support 2 fixedly connected to one side of the base frame 1, a second support 3 fixedly connected to one end of the first support 2, and a top support cylinder 4 fixedly connected to one side of the second support 3; and a fixing assembly for fixing the pipeline to be tested, which is connected to the pipeline body. This pipeline pressure testing and support device not only achieves uniform clamping of the pipeline body, reducing damage and improving the accuracy of test data, but also simplifies the pipeline fixing process and improves testing efficiency.
[0027] like Figure 2 and Figure 5 As shown, the fixing assembly includes a Y-shaped support plate 5 supported at the bottom of the pipe body and a clamping plate 6 clamped at the top of the pipe body. A base 7 is installed at the bottom of the Y-shaped support plate 5. Connecting brackets 8 are rotatably connected to both sides of the Y-shaped support plate 5. Support blocks 9 are fixedly connected to both sides of the base 7. A baffle 10 is fixedly connected to one side of the support block 9. Connecting brackets 11 are rotatably connected to the inner walls of the support blocks 9. The end of the connecting bracket 11 away from the support block 9 is hinged to the clamping plate 6. The end of the connecting bracket 8 away from the Y-shaped support plate 5 is hinged to the connecting bracket 11.
[0028] The core outer diameter of commonly used engineering energy transmission pipelines is mostly 335 mm, with a weight of 16.3 kg per meter. When the pipeline body is placed on top of the Y-shaped support plate 5, the Y-shaped support plate 5 will sink within the base 7 due to the weight of the pipeline body. Simultaneously, the connecting brackets 8 on both sides of the Y-shaped support plate 5 move downwards, causing the connecting bracket 11 to rotate around the support block 9. This allows the clamping plate 6 to gradually approach and clamp the pipeline body, simplifying the fixing process and achieving initial fixation of the pipeline body. If it is found that the weight of the pipeline body is insufficient to allow the Y-shaped support plate 5 to sink completely, resulting in the clamping plate 6 not adhering to the outer wall of the pipeline body, the worker can... Press down on the pipe body or push the clamp 6 to make the clamp 6 fit against the outer wall of the pipe body. In the fitted state, the rubber pad at the bottom of the Y-shaped support plate 5 will contact the base 7, and at this time, the insertion hole 12 opened on the Y-shaped support plate 5 will be flush with the insertion groove 13 opened on the base 7. At this time, the insertion rod 15 can be inserted into the insertion groove 13 and the insertion hole 12 to fix the Y-shaped support plate 5. When the pipe body is removed from the Y-shaped support plate 5, the connecting bracket 11 will unfold outward. After unfolding to a certain angle, it will be restricted by the baffle 10 on the support block 9 to prevent excessive unfolding and ensure that the clamp 6 is released smoothly, which facilitates the removal and reinstallation of the pipe body.
[0029] like Figure 4 and Figure 6 As shown, the outer wall of the Y-shaped support plate 5 is provided with a plug hole 12, the outer wall of the base 7 is provided with a plug groove 13, the inner wall of the plug groove 13 is provided with a groove 14, the inner wall of the plug hole 12 is provided with a plug rod 15, the plug rod 15 is slidably inserted into the plug groove 13, and the outer wall of the plug rod 15 is fixedly connected with a protrusion 16, and the protrusion 16 matches the shape of the groove 14 of the plug groove 13.
[0030] After the pipe body is clamped by the fixing component, the plug rod 15 can be inserted into the plug groove 13 and the plug hole 12 in sequence, and the plug rod 15 can be rotated 90 degrees clockwise. The plug rod 15 is locked by the engagement of the protrusion 16 and the groove 14, which ensures that the Y-shaped support plate 5 is fixed inside the base 7. This achieves secondary reinforcement of the fixing component, prevents the pipe body from shifting during the test, improves the safety and reliability of the test, and ensures the accuracy of the data.
[0031] The workflow of the technical solution provided by this utility model is as follows: In use, first place the pipe body on top of the Y-shaped support plate 5. The Y-shaped support plate 5 will sink within the base 7 due to the weight of the pipe body. Simultaneously, the connecting brackets 8 on both sides of the Y-shaped support plate 5 move downwards, causing the connecting bracket 11 to rotate around the support block 9. This allows the clamping plate 6 to gradually approach and clamp the pipe body, achieving initial fixation. If the weight of the pipe body is insufficient to completely sink the Y-shaped support plate 5, resulting in the clamping plate 6 not adhering to the outer wall of the pipe body, the operator can press down on the pipe body or push the clamping plate 6 to adhere it to the outer wall of the pipe body. When the Y-shaped support plate 5 is in the mating state, the rubber pad at the bottom will contact the base 7, and the insertion hole 12 on the Y-shaped support plate 5 will be flush with the insertion groove 13 on the base 7. At this time, the insertion rod 15 can be inserted into the insertion groove 13 and the insertion hole 12 to fix the Y-shaped support plate 5. Then, the insertion rod 15 is rotated 90 degrees clockwise, and the protrusion 16 will be locked in the groove 14 on the base 7, thereby locking the insertion rod 15. The Y-shaped support plate 5 will then be fixed inside the base 7, ensuring that the pipe body is stable and without displacement during the test, and improving the overall stability of the fixing component.
[0032] Once the pipeline is secured, relevant tests can be conducted on the pipeline body. During the test, the top support cylinder 4, located in the pit, will support the flange blind plate at the pipeline body connection, ensuring that the connection will not loosen due to pressure changes inside the pipeline body, thereby maintaining the sealing and stability of the pipeline connection. The force received will be transmitted to the wall of the pit through the first support 2, releasing the axial thrust in a directional manner and stabilizing the pipeline body. At the same time, the design of the top support cylinder 4 allows it to automatically adjust the support force according to pressure changes, adapting to different test conditions, further ensuring the accuracy of test data and the safety of the test process.
[0033] After the test, rotate the plug rod 15 counterclockwise by 90 degrees, and the protrusion 16 will disengage from the groove 14. Then, pull the plug rod 15 outward to remove it from the plug hole 12 on the Y-shaped support plate 5. After removing the plug rod 15, the Y-shaped support plate 5 loses its fixing effect between the plug rod 15 and the base 7. At this point, the Y-shaped support plate 5 is in a non-fixed state and can move inside the base 7. Because the Y-shaped support plate 5 is no longer fixed by the plug rod 15 and the clamping plate 6 and the connecting bracket 11 are hinged, a gap will form between the clamping plate 6 and the pipe body. Then, use machinery to slowly lift the pipe body upward. During the lifting process, the outer wall of the pipe body will slide along the arc surface of the clamping plate 6. This sliding process will generate an outward pushing force on the clamping plate 6. The hinged relationship between the connecting brackets 11 causes the upper end of the clamping plate 6 to unfold slightly outward, further prompting the connecting brackets 11 to unfold to both sides, actively making room for the pipe body. The Y-shaped support plate 5, which gradually loses the pressure of the weight of the pipe body, will also move upward close to the bottom of the pipe body under the pull of the external connecting brackets 11. With the continuous movement of the pipe body, the gap between the clamping plate 6 and the pipe body will become larger and larger, ensuring that the connecting brackets 11 unfold smoothly. At this time, the pipe body can be completely separated from the fixed range of the fixing components. The pipe body can be lifted mechanically. After unfolding to a certain angle, the connecting brackets 11 will contact the baffle 10 on the support block 9. The baffle 10 will limit the unfolding range of the connecting brackets 11 to prevent over-unfolding, making it easy to remove and reinstall the pipe body. The whole process is simple and efficient.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
