[0023] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, the specific solution of this embodiment is: a mobile pipeline pressure testing tool, including a support plate 3, the side end of the support plate 3 is provided with a pressure gauge 6 and a pressure pump 11; including a base plate 1, the base plate 1 is provided with a lifting device 13, the lifting device 13 is provided with a support plate 3, the two ends of the support plate 3 are movably provided with clamping components 4 for fixing the pipeline, and the middle part is movably provided with a clamping component 5.

[0025] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the lifting device 13 is a shear-type lifting device; telescopic devices 2 are provided on both sides of the lifting device 13, and the telescopic devices 2 include a rod sleeve 201, and a rod body 202 is provided in the rod sleeve 201, and the rod sleeve 201 and the rod body 202 are gap-fitted.

[0026] like Figure 2 As shown, as a preferred embodiment of the above embodiment, the clamping assembly 4 includes an upper clamping block 401 and a lower clamping block 403, and the middle parts of the upper clamping block 401 and the lower clamping block 403 are set to be arc-shaped and suitable for the shape of the pipeline; the two ends of the upper clamping block 401 and the lower clamping block 403 are connected by bolts 402; and a vertical plate 404 is provided at the lower end of the bolt 402.

[0027] like Figure 3 As shown, as a preferred embodiment of the above embodiment, the clamping assembly 5 includes a mounting frame 501, the mounting frame 501 is L-shaped, a cylinder 502 is provided at the lower end of the mounting frame 501, the telescopic end of the cylinder 502 is connected to the mounting block 503, and a clamping block 504 is provided at the lower end of the mounting block 503.

[0028] like Figure 1As shown, as a preferred embodiment of the above embodiment, the pressure gauge 6, buffer tube 7, and needle valve 8 are threadedly connected to the connecting rod 14; the connecting rod 14 is also threadedly connected to the pipeline. The pressure pump 11 is connected to the pipeline via the connector 9 and the connecting tube 10, and the connector 9 is also threadedly connected to the pipeline.

[0029] The working principle of this utility model:

[0030] The tooling is moved via universal wheels 12 on the base plate 1, allowing it to be easily moved to the location on the pipeline requiring pressure testing. The lifting mechanism 13 (a shear lift) allows the support plate 3 to move vertically up and down, enabling the tooling to be quickly adjusted to the desired working height. The telescopic mechanism 2, comprising a rod sleeve 201 and a rod body 202, provides guidance during height adjustment.

[0031] The clamping assembly 4 comprises an upper clamping block 401 and a lower clamping block 403, which secure the pipe using bolts 402 and a vertical plate 404. The arc-shaped design of the clamping block allows the assembly to accommodate pipes of varying diameters. The compression assembly 5 adjusts the height of the compression block 504 by retracting and extending the cylinder 502, ensuring that the compression block 504 can effectively compress the pipe and ensure stability and safety during the pressure test.

[0032] The combination of the pressure gauge 6, the buffer tube 7, the needle valve 8 and the connecting rod 14 is used to monitor and control the pressure in the pipeline.

[0033] The pressure pump 11 delivers pressure into the pipeline through the connector 9.

[0034] Working process:

[0035] The operator moves the tooling to the designated pipeline position and uses the universal wheels 12 to achieve flexible movement. According to the actual height of the pipeline, the operator adjusts the height of the support plate 3 through the shear lift device 13. The telescopic device 2 has a guiding function, which improves the flexibility of use.

[0036] Fixed pipe:

[0037] The operator places the pipe into the lower clamping block 403 of the clamping assembly 4, adjusts it to the appropriate position, and then fixes the upper clamping block 401 and the lower clamping block 403 with bolts 402. The arc-shaped design of the upper clamping block 401 and the lower clamping block 403 ensures adaptability to pipes of different diameters.

[0038] Connect pressure test equipment:

[0039] The operator threadably connects the pressure gauge 6, the buffer tube 7, the needle valve 8 and the connecting rod 14, and ensures that the connection between the connecting rod 14 and the pipeline is firm.

[0040] Apply pressure:

[0041] Start the pressure pump 11 and deliver the pressure medium to the pipeline through the connector 9. The pressure gauge 6 displays the pressure in the pipeline in real time, and the needle valve 8 is used to fine-tune the pressure.

[0042] Recording data:

[0043] During the pressure test, the operator monitors the reading of the pressure gauge 6 to ensure that the pressure remains within the predetermined safety range.

[0044] At the same time, the pressure data is recorded for subsequent analysis.

[0045] Pressure test completed:

[0046] Once the test is completed, the operator releases the pressure through the needle valve 8, then removes the pressure test equipment from the pipeline and moves the tooling to the next test position.

[0047] Through the above working principle and working process, the mobile pipeline pressure testing tool can perform pipeline pressure testing work efficiently and safely, while ensuring the convenience and flexibility of operation.
