Description

Technical Field

[0001] This utility model relates to the field of pipeline pressure testing technology, and in particular to a pipeline pressure testing device. Background Technology

[0002] Due to the pressure, temperature changes, and external environmental influences that pipelines may face, pressure testing of pipeline systems can help identify potential leaks, weaknesses, or defects, ensuring that pipelines will not leak or experience sudden failures under normal operating pressure. For pipeline pressure testing, electric pipeline pressure testing pumps are usually used. The plunger pump of the electric pipeline pressure testing pump usually uses hydraulic or pneumatic technology to generate high-pressure liquid or gas, which is applied to the pipeline under test to verify its sealing and pressure resistance performance under specific pressure.

[0003] In existing technologies, electric pressure testing pumps typically require connecting pipes to the pipeline under test when conducting pipeline pressure tests. However, when the electric pressure testing pump is placed directly on the ground, it is easily subject to external impacts, which can cause the connecting pipe between the electric pressure testing pump and the pipeline under test to be pulled off by external forces, thus affecting the pipeline pressure test results. To address this, we propose a pipeline pressure testing device. Utility Model Content

[0004] The main objective of this invention is to provide a pipeline pressure testing device. A pipe clamping mechanism is installed outside the test pump body below the test joint. This mechanism provides a pipe clamping structure outside the test pump body. The connecting pipe between the test pump body and the pipe to be tested can be clamped by the pipe clamping mechanism. When the test pump body is subjected to external force, it ensures that the connecting pipe at the test pump body is not easily pulled off by the external force. Furthermore, a bending support plate is installed on the outside of the test pump body, which, together with a T-shaped base plate, obtains three-point support on the ground, thereby improving the stability of the test pump body on the ground. This makes it less likely for the test pump body to tip over during pipeline pressure testing, preventing the connecting pipe between the test pump body and the pipe to be tested from being detached due to external forces. This effectively solves the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipeline pressure testing device includes a test pump body and a test connector. The test connector is installed on the outer side of one side of the test pump body. The device also includes a pipe pressing mechanism, which includes a wall plate, a support strip, a U-shaped plate, a C-shaped support plate, a C-shaped pressure plate, a connecting platform, a pressure strip, and a fixing block. The wall plate is bolted to the outer side of the test pump body below the test connector. The back plate of the wall plate has vertical feet of the U-shaped plate welded to its outer surface via the support strip. The U-shaped plate has symmetrically formed U-shaped grooves on its surface facing the test connector. The C-shaped support plate, communicating with the U-shaped grooves, is welded to the surface of the U-shaped plate away from the test connector. A C-shaped pressure plate is pressed onto the surface of the C-shaped support plate. A pressure strip is welded to the upper surface of the C-shaped pressure plate via the connecting platform. The pressure strip is bolted to the top surface of the U-shaped plate. A fixing groove for mounting the fixing block is formed on the surface of the U-shaped plate below the pressure strip. The fixing block is integrally formed on the lower surface of the pressure strip.

[0007] Furthermore, the other three sides of the test pump body away from the test joint are bolted with bent support plates, and the bottom plate of the bent support plate is welded with a T-shaped base plate for contacting the ground.

[0008] By adopting the above technical solution, after the bending support plate is bolted to the three sides of the test pump body, the bending support plate is pressed against the ground with a T-shaped base plate to obtain stable lateral support and prevent the test pump body from tipping over.

[0009] Furthermore, the connecting platform is inserted and welded between the two sets of plates of the C-shaped pressure plate, and the upper platform surface of the connecting platform is the side strip surface of the pressure strip welded to the platform.

[0010] By adopting the above technical solution, after the joints are welded between the C-shaped pressure plates, they can be connected to the pressure strips using their own platform.

[0011] Furthermore, the height of the fixed block is less than the depth of the groove, and two sets of fixed blocks are provided on the lower surface of the pressure strip;

[0012] By adopting the above technical solution, the fixed block can be smoothly inserted into the fixed slot for positioning and mounting.

[0013] Furthermore, vertical mounting holes are provided on the body of the pressure strip and the U-shaped plate, and bolts are vertically screwed between the vertical mounting holes of the pressure strip and the U-shaped plate;

[0014] By adopting the above technical solution, bolts can be screwed into the vertical mounting holes of the pressure strip and the U-shaped plate, thereby pressing the pressure strip onto the top of the U-shaped plate.

[0015] Furthermore, mounting holes are provided on the surface of the casing of the wall-mounted plate and the test pump body, and bolts are screwed between the mounting holes of the wall-mounted plate and the test pump body.

[0016] By adopting the above technical solution, after screwing bolts into the mounting holes between the wall-mounted plate and the test pump body, the wall-mounted plate can be pressed onto the test pump body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a pipe clamping mechanism outside the test pump body below the test joint. The pipe clamping mechanism provides a pipe clamping structure outside the test pump body. The connecting pipe between the test pump body and the pipe to be tested can be clamped by the pipe clamping mechanism. When the test pump body is subjected to external force, it ensures that the connecting pipe at the test pump body is not easily pulled off by the external force.

[0019] Furthermore, the outer side of the pressure testing pump body is equipped with a bending support plate and a T-shaped base plate to obtain three-point support on the ground, thereby improving the stability of the pressure testing pump body on the ground. This makes the pressure testing pump body less likely to tip over due to external forces during pipeline pressure testing, and prevents the connecting pipe between the pressure testing pump body and the pipeline to be tested from being detached due to external forces.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figs. 1-3As shown, a pipeline pressure testing device includes a test pump body 1 and a test connector 2. The test connector 2 is installed on the outer side of one side of the test pump body 1. It also includes a pipe pressing mechanism 3, which includes a wall mounting plate 4, support bars 5, a U-shaped plate 6, a C-shaped support plate 8, a C-shaped pressure plate 9, a connecting platform 10, a pressure strip 11, and a fixing block 12. The wall mounting plate 4 is bolted to the outer side of the test pump body 1 below the test connector 2. The back plate of the wall mounting plate 4 has vertical feet of the U-shaped plate 6 welded to its outer surface via support bars 5. The U-shaped plate 6 has symmetrically formed U-shaped grooves 7 on its surface facing the test joint 2. A C-shaped support plate 8 that communicates with the U-shaped grooves 7 is welded to the surface of the U-shaped plate 6 away from the test joint 2. A C-shaped pressure plate 9 is pressed onto the surface of the C-shaped support plate 8. A pressure strip 11 is welded to the upper surface of the C-shaped pressure plate 9 through a connecting plate 10. The pressure strip 11 is locked to the top surface of the U-shaped plate 6 by bolts. A fixing groove 13 for mounting the fixing block 12 is formed on the surface of the U-shaped plate 6 below the pressure strip 11. The fixing block 12 is integrally formed on the lower surface of the pressure strip 11.

[0026] Among them, the other three sides of the test pressure pump body 1 away from the test pressure connector 2 are bolted with a bent support plate 14, and the bottom plate of the bent support plate 14 is welded with a T-shaped base plate 15 for contacting the ground.

[0027] By adopting the above technical solution, after the bending support plate 14 is bolted to the three sides of the test pump body 1, the bending support plate 14 is pressed against the ground by the T-shaped base plate 15 to obtain stable lateral support and prevent the test pump body 1 from tipping over.

[0028] The connecting platform 10 is inserted and welded between the two sets of plates of the C-shaped pressure plate 9, and the upper platform surface of the connecting platform 10 is the side strip surface of the pressure strip 11 welded to the platform.

[0029] By adopting the above technical solution, after the connecting plate 10 is welded between the C-shaped pressure plates 9, it can connect to the pressure strip 11 with the help of its own plate.

[0030] Wherein, the height of the fixed block 12 is less than the depth of the groove 13, and two sets of fixed blocks 12 are provided on the lower surface of the pressure strip 11.

[0031] By adopting the above technical solution, the fixed block 12 can be smoothly inserted into the fixed slot 13 for positioning and mounting.

[0032] Vertical mounting holes are provided at the plate bodies of the pressure strip 11 and the U-shaped plate 6, and vertical bolts are screwed between the vertical mounting holes of the pressure strip 11 and the U-shaped plate 6.

[0033] By adopting the above technical solution, bolts can be screwed into the vertical mounting holes of the pressure strip 11 and the U-shaped plate 6, thereby pressing the pressure strip 11 onto the top of the U-shaped plate 6.

[0034] The wall mounting plate 4 and the test pump body 1 have mounting holes on their respective chassis surfaces, and bolts are screwed between the mounting holes of the wall mounting plate 4 and the test pump body 1.

[0035] By adopting the above technical solution, after screwing bolts into the mounting holes of the wall-mounted plate 4 and the test pump body 1, the wall-mounted plate 4 can be pressed onto the test pump body 1.

[0036] It should be noted that this utility model is a pipeline pressure testing device. After the pressure testing joint 2 is installed outside the pressure testing pump body 1, the pressure pipe mechanism 3 is installed outside the test pump body 1 with bolts. The wall plate 4 of the pressure pipe mechanism 3 is then bolted to the outside of the test pump body 1. The wall plate 4 is supported by the support bar 5 on the ground. When the pipeline needs to be pressure tested, one end of the connecting pipe can be screwed on at the pressure testing joint 2. Then the other end of the connecting pipe is connected to the pipeline to be tested to provide a pressure source, thereby applying pressure to the test pipeline. Then the connecting pipe can be placed into the U-shaped groove 7 and C-shaped support plate 8 of the U-shaped plate 6 and supported. Then the pressure bar 11 is inserted into the fixed groove 13 of the U-shaped plate 6 by the fixed block 12. Then the pressure bar 11 is locked and pressed into the U-shaped plate with bolts. At the top, the pressure strip 11, connected by the C-shaped pressure plate 9 to the connecting platform 10, can press the connecting pipe onto the C-shaped support plate 8, making the connecting pipe less likely to be pulled. The outer side of the test pump body 1 is also equipped with a bending support plate 14, which, together with the T-shaped base plate 15, obtains three-point support on the ground, thereby improving the stability of the test pump body 1 on the ground. This makes it less likely for the test pump body 1 to tip over due to external forces during the pipeline pressure test, and prevents the connecting pipe between the test pump body 1 and the pipeline to be tested from being affected by external forces and falling off. After the pipeline pressure test is completed, the bolts on the pressure strip 11 can be unscrewed and removed. Then, the pressure strip 11, along with the connecting platform 10 and the C-shaped support plate 8, can be removed by the workers. At this time, the connecting pipe between the test joint 2 and the test pump body 1 can be disassembled.
