Description

Technical Field

[0001] This application relates to the field of pipeline testing equipment technology, and in particular to a fluid pipeline vibration testing device. Background Technology

[0002] Pipes are tubular or hollow cylinders, usually but not necessarily circular, and are mainly used to transport fluids—liquids, gases, slurries, powders, or large quantities of small solids. They can also be used in structural applications. Pipes are a facility used in almost all industrial sectors. Pipes are often connected together by ring-shaped pipe connectors (such as clamps). Some pipes are often buried underground or inside building walls. If the pipe connectors between pipes are not properly sealed, leaks can easily occur, often resulting in significant economic losses.

[0003] Vibration is a major factor leading to pipeline structural damage and accidents, making pipeline displacement and even damage more likely. This not only affects the safety and stability of pipe supports but also poses a threat to the safety of surrounding pipelines. Pipeline vibration is caused by both internal water impacts and external collisions. To avoid damage to pipeline structures due to vibration, vibration testing has become an essential step in the current pipe fitting production process to verify whether pipeline connections meet connection standards. However, current pipeline testing equipment has a simple structure. Most of them first connect two pipes to each other with connectors, fix both ends of the pipe, seal both ends of the pipe, and inject water into the pipe. Then, the equipment vibrates the connection point of the pipes up and down to determine whether there is leakage. The test result is obtained by checking for leaks. The testing method is too simplistic, has limited testing effect on the pipeline, makes it difficult to determine whether the pipeline is truly tightly connected, and the accuracy of the test results is insufficient. Summary of the Invention

[0004] To improve the accuracy of pipeline vibration test results, this application provides a fluid pipeline vibration test device.

[0005] This application provides a fluid pipeline vibration testing device, which adopts the following technical solution: A fluid pipeline vibration testing device includes a machine base. A fixed base is mounted on the top of the machine base, the fixed bases being arranged in a mirror-symmetrical manner. A fixed cover is installed on the top of the fixed base. A lifting seat is slidably connected to the top of the machine base, the lifting seat being located between the fixed bases. A lifting cover is slidably mounted on the top of the lifting seat. A locking assembly for fixing the lifting cover is provided on the top of the lifting seat. A placement cavity is formed in the side wall of the machine base. A lifting drive component for driving the lifting seat to move up and down is provided on the bottom wall of the placement cavity. A sliding seat is slidably connected to the top side of the machine base. The sliding seat slides horizontally. A side vibration frame is provided on the top of the sliding seat. A first vibration block is provided on the side wall of the side vibration frame. A sliding drive component for driving the sliding seat to move is provided on the top of the machine base.

[0006] By adopting the above technical solution, when pipeline testing is required, the pipeline is installed on a fixed base and a lifting base. The pipeline connectors at both ends are sealed, and water is injected into the pipeline connectors and the inside of the pipe body. The lifting drive unit drives the lifting base to move up and down, thereby causing the connection between the pipe body and the pipeline connector to vibrate up and down, performing a preliminary inspection of the pipeline. After the preliminary inspection is completed, the sliding drive unit drives the sliding base and the first vibration block to slide back and forth, causing the first vibration block to repeatedly impact the side wall of the pipe body, thereby performing a multi-directional vibration test on the pipeline. At this time, the staff can observe whether there is water leakage between the pipe body and the pipeline connector, thereby determining whether the pipeline is tightly connected, which can improve the accuracy of the pipeline vibration test results.

[0007] Optionally, the first vibration blocks are symmetrically arranged at both ends of the side vibration frame, the side vibration frame is rotatably connected to the sliding seat, and the top of the sliding seat is provided with a rotation drive for driving the side vibration frame to rotate.

[0008] By adopting the above technical solution, before the sliding drive component drives the sliding seat and the first vibration block to complete the sliding impact, the rotation drive component can drive the side vibration frame to rotate, so that the side vibration frame can impact the outer walls of the two pipes back and forth through the first vibration block. By using the new impact method to conduct vibration tests on the two pipes, the staff can judge the tightness of the pipe connection by whether the pipe leaks, thus improving the accuracy and reliability of the test.

[0009] Optionally, a sliding block is slidably connected to the top side of the machine tool. The sliding block is connected to the sliding seat, and the sliding direction of the sliding block is consistent with the sliding direction of the sliding seat. A sliding frame is provided on the top of the sliding block, and a second vibration block is provided on the side wall of the sliding frame.

[0010] By adopting the above technical solution, when the sliding drive drives the sliding seat to slide, since the sliding seat is connected to the sliding block, the sliding seat drives the sliding block and the sliding frame to slide synchronously, so that the first vibration block and the second vibration block alternately impact and vibrate the two sides of the pipe. The tightness of the pipe connection can be judged by whether the pipe leaks after a certain number of impact vibrations, thus improving the accuracy and reliability of the test results.

[0011] Optionally, the second vibration blocks are symmetrically arranged at both ends of the sliding frame. The sliding frame is rotatably connected to the sliding seat. A sliding rod is slidably connected to the bottom of the sliding frame. The sliding rod is rotatably engaged with the sliding frame. A connecting rod is provided at the bottom end of the sliding rod. The end of the connecting rod away from the sliding rod is located between the side vibration frame and the sliding seat. A threaded linkage is connected to the top of the side vibration frame. The threaded linkage is inserted into the end of the connecting rod.

[0012] By adopting the above technical solution, when the rotating drive unit drives the side vibration frame to rotate, the side vibration frame pulls the connecting rod and the sliding rod through the threaded linkage, thereby causing the sliding rod to pull the sliding frame to rotate, so that the sliding frame alternately impacts and vibrates the outer walls of the two tubes through the second vibration block, thereby causing the first vibration block and the second vibration block to alternately impact the tubes, improving the test efficiency, and improving the accuracy and reliability of the test results by conducting tests through diversified vibration modes.

[0013] Optionally, a first rod is rotatably connected to the side wall of the sliding seat, and a second rod is rotatably connected to the side wall of the sliding seat. A locking block is rotatably connected to the end of the second rod, and the locking block is inserted into the first rod.

[0014] By adopting the above technical solution, multiple fixed seats, fixed covers, lifting seats and lifting covers can be set on the machine platform. A sliding seat is set on each of the opposite sides of the sliding seat. The first section rod and the second section rod are connected to each other by a snap-fit ​​block, so that the sliding seat and the sliding seat are connected. When the sliding seat is driven to move, the other sliding seats can be driven to slide. The first vibration block and the second vibration block can cause the two sets of pipes to impact and vibrate, and the two sets of pipes can be tested at the same time, which can improve the test efficiency.

[0015] Optionally, a snap-fit ​​groove is provided on the top side of the first section rod, the snap-fit ​​block is inserted into the snap-fit ​​groove, the snap-fit ​​block is T-shaped, the snap-fit ​​groove is T-shaped, and the side wall of the snap-fit ​​block abuts against the groove wall of the snap-fit ​​groove.

[0016] By adopting the above technical solution, the locking block is rotated and inserted into the locking groove. After the locking block is inserted into the locking groove, since the locking block is T-shaped, it is not easy to fall out of the locking groove when moving laterally, so that the first section rod and the second section rod maintain a stable connection.

[0017] Optionally, a first pad is inserted into the side wall of the first vibrating block, and a second pad is inserted into the side wall of the second vibrating block.

[0018] By adopting the above technical solution, when the first vibrating block and the second vibrating block impact the pipe body, the first pad can reduce the damage to the first vibrating block during impact, and the second pad can reduce the damage to the second vibrating block during impact.

[0019] Optionally, the bottom of the side vibration frame is provided with a rotating rod, the bottom end of which is rotatably connected to the top of the sliding seat, and the bottom side of the side vibration frame is provided with an arc-shaped sliding plate, the bottom of which slides and engages with the top side of the sliding seat.

[0020] By adopting the above technical solution, when the side vibration frame rotates, the arc plate can guide and support the side vibration frame, reducing the force on the rotating rod. When the first vibration block impacts the tube body, the arc plate can share the impact reaction force for the rotating rod, thus protecting the rotating rod and the side vibration frame.

[0021] Optionally, the locking assembly includes a locking rod disposed on the top of the landing seat, an adjusting block disposed on the top side of the landing seat, the locking rod intersecting with the adjusting block, the bottom side of the landing cover abutting against the top side of the adjusting block, the locking rod extending out of the top side of the landing cover, and a threaded locking member disposed on the top side of the landing cover, the threaded locking member being threadedly connected to the locking rod.

[0022] By adopting the above technical solution, when testing is required, the pipe connector can be fixed by the lifting seat and lifting cover. The adjustment blocks of different heights can be replaced according to the size of the pipe body and pipe connector, so that the lifting seat and lifting cover can be adapted to different pipe bodies and pipe connectors.

[0023] Optionally, the side wall of the placement cavity is provided with a slide rail, which extends vertically. The output end of the lifting and lowering drive is connected to a lifting and lowering wheel. The side wall of the lifting and lowering wheel is connected to an eccentric lifting and lowering rod. The end of the eccentric lifting and lowering rod is rotatably connected to a lifting frame. The lifting frame is slidably connected to the slide rail, and the top of the lifting frame is connected to the lifting and lowering seat.

[0024] By adopting the above technical solution, the lifting and lowering drive component can drive the lifting and lowering wheels to rotate, thereby driving the lifting frame to lift and lower, thus causing the lifting seat to move up and down. When the lifting frame slides, the slide rail can guide the slider and the lifting frame, reducing the possibility of deviation when the lifting frame slides.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When pipeline testing is required, install the pipeline on the fixed base and the lifting base, seal the pipeline connectors at both ends, and fill the pipeline connectors and the inside of the pipe body with water. Then, drive the lifting base to move up and down, thereby vibrating the connection between the pipe body and the pipeline connector to perform a preliminary inspection of the pipeline. After the preliminary inspection is completed, drive the sliding base and the first vibration block to slide back and forth, causing the first vibration block to repeatedly impact the side wall of the pipe body, thereby performing a multi-directional vibration test on the pipeline. At this time, the staff can observe whether there is water leakage between the pipe body and the pipeline connector, thereby determining whether the pipeline is tightly connected, which can improve the accuracy of the pipeline vibration test results. 2. When the side vibration frame rotates, the arc plate can guide and support the side vibration frame, reducing the force on the rotating rod. When the first vibration block impacts the tube body, the arc plate can share the impact reaction force for the rotating rod, thus protecting the rotating rod and the side vibration frame. 3. When the side vibration frame rotates, the arc plate can guide and support the side vibration frame, reducing the force on the rotating rod. When the first vibration block impacts the tube body, the arc plate can share the impact reaction force of the rotating rod, thus protecting the rotating rod and the side vibration frame.

[0033] This application discloses a fluid pipeline vibration testing device.

The top side of the fixed base 11 has an upward-facing slot for placing a pipe connector. The fixed base 11 is arranged in a mirror-symmetrical manner. A fixed cover 12 is mounted on the top of the fixed base 11. The bottom side of the fixed cover 12 has a downward-facing slot corresponding to the fixed base 11. A screw is mounted on the top side of the fixed base 11, and the screw passes through the bottom side of the fixed cover 12. The top side of the fixed cover 12 is provided with an external hexagonal nut, which is threadedly connected to the screw. The bottom side of the external hexagonal nut abuts against the top side of the fixed cover 12. The top of the machine base 1 is slidably connected to the lifting seat 2, which slides vertically. The top side of the lifting seat 2 is provided with an upward-facing slot for placing a pipe connector. The lifting seat 2 is located between the fixed seats 11, which are arranged in a straight line. The top of the lifting seat 2 is provided with a lifting cover 21, and the bottom side of the lifting cover 21 is provided with... The machine tool 1 has a downward-facing slot corresponding to the landing seat 2. A locking assembly is provided on the top of the landing seat 2 to fix the landing cover 21 to the top of the landing seat 2. A placement cavity 13 is provided on the side wall of the machine tool 1. A landing drive component 14, which is a servo motor, is provided on the bottom wall of the placement cavity 13. A landing wheel 15, which is an eccentric wheel, is connected to the output end of the landing drive component 14. The side of the landing wheel 15 facing away from the landing drive component 14 is connected to... An eccentric lifting boom 16 is provided, with a lifting frame 17 rotatably connected to the end of the eccentric lifting boom 16 away from the lifting wheel 15. The lifting frame 17 is slidably connected to the side wall of the placement cavity 13 and slides vertically. The top of the lifting frame 17 is connected to the lifting seat 2, and the bottom of the lifting seat 2 is fixed to the top side of the lifting frame 17 by a threaded rod and an external hexagonal nut. The lifting drive component 14 can drive the lifting wheel 15 to rotate, thereby causing the lifting frame 17 to rise and fall, thus causing the lifting seat 2 to move up and down. (Refer to...) Figure 1 and Figure 3A sliding seat 33 is slidably connected to the top side of the machine base 1. The sliding seat 33 slides horizontally. The arrangement direction between the fixed seat 11 and the lifting seat 2 is perpendicular to the sliding direction of the sliding seat 33. A sliding drive 3, which is a servo motor, is provided on the top of the machine base 1. The output end of the sliding drive 3 is connected to a rotating disk 31, which is an eccentric wheel. The output end of the sliding drive 3 is connected to the midpoint of the rotating disk 31. A connecting rod 32 is rotatably connected to the side of the rotating disk 31 away from the sliding drive 3. The connecting rod 32 is rotatably connected to the rotating disk 31. The rotation axis between the disks 31 is offset from the rotation axis of the rotating disk 31. The end of the connecting rod 32 away from the rotating disk 31 is rotatably connected to the sliding seat 33. The sliding drive 3 can drive the rotating disk 31 to rotate, thereby driving the connecting rod 32 to rotate, and thus dragging the sliding seat 33 to slide. A side vibration frame 34 is provided on the top side of the sliding seat 33. The side vibration frame 34 extends in the horizontal direction. The arrangement direction between the fixed seat 11 and the lifting seat 2 is consistent with the extension direction of the side vibration frame 34. A first vibration block 35 is provided on the side wall of the side vibration frame 34.

[0035] Reference Figure 1 and Figure 2 A water tank 5 is provided on the bottom wall of the placement cavity 13. A water pump (not shown in the figure) is provided in the water tank 5. A water delivery pipe 51 is provided in the water tank 5. The end of the water delivery pipe 51 away from the water tank 5 extends out of the top side of the machine base 1. The water delivery pipe 51 can pump the water inside the water tank 5 to the top of the machine base 1 through the water pump.

[0036] When pipeline testing is required, bring the ends of two pipes close together and connect and fix them together using pipe connectors (such as clamps). Install a pipe connector at each of the two pipes' far ends. Place the pipe connector between the two pipes on the top side of the lifting seat 2, and cover the top side of the lifting cover 21 with the bottom side. Fix the pipe connector between the two pipes to the lifting seat 2 using locking components and the lifting cover 21. Place the pipe connectors at both ends of the pipe on the fixing seat 11, and insert the fixing cover 12 into the screw on the top of the fixing seat 11, so that the bottom side of the fixing cover 12 covers the top side of the pipe connector. Thread the external hexagonal nut to the screw, and fix the pipe connector to the fixing seat 11. The pipe connector is sealed, and the water supply pipe 51 is inserted into the pipe connector. Water is injected into the pipe connector and the inside of the pipe body. The lifting drive 14 drives the lifting wheel 15 to rotate, and the lifting seat 2 moves up and down, thereby vibrating the connection position between the pipe body and the pipe connector to perform a preliminary inspection of the pipe. After the preliminary inspection is completed, the lifting drive 14 drives the lifting seat 2 to reset, and the sliding drive 3 drives the rotating disk 31 to rotate, thereby causing the sliding seat 33 and the first vibration block 35 to slide back and forth, causing the first vibration block 35 to repeatedly impact the side wall of the pipe body, thereby performing a multi-directional vibration test on the pipe. At this time, the staff can observe whether there is water leakage between the pipe body and the pipe connector, thereby judging whether the pipe is connected tightly, which can improve the accuracy of the pipe vibration test results.

[0037] Reference Figure 1 and Figure 4 The locking assembly includes a locking rod 22 located on the top of the landing seat 2. The locking rod 22 is fixed to the top side of the landing seat 2 and extends vertically. An adjusting block 23 is provided on the top side of the landing seat 2. The locking rod 22 and the adjusting block 23 are interlocked. The locking rod 22 passes through the adjusting block 23 from bottom to top. The adjusting block 23 is a rubber block. The bottom side of the landing cover 21 abuts against the top side of the adjusting block 23. The top end of the locking rod 22 protrudes from the top side of the landing cover 21. A threaded locking member 24 is provided on the top side of the landing cover 21. The threaded locking member 24 is a nut. The threaded locking member 24 is threadedly connected to the locking rod 22. The bottom side of the threaded locking member 24 abuts against the top side of the landing cover 21.

[0038] When testing is required, place the pipe connector in the top slot of the lifting seat 2, insert the locking rod 22 into the adjusting block 23, and let the locking rod 22 pass through the adjusting block 23. Cover the top of the pipe connector with the lifting cover 21, let the locking rod 22 pass through the lifting cover 21, and let the threaded locking member 24 be threadedly connected to the locking rod 22. Place the bottom side of the lifting cover 21 against the top side of the adjusting block 23. The adjusting block 23 of different heights can be replaced according to the size of the pipe body and the pipe connector to change the distance between the lifting seat 2 and the lifting cover 21, so that the lifting seat 2 and the lifting cover 21 can be adapted to different pipe bodies and pipe connectors.

[0039] Reference Figure 1 and Figure 3 The first vibration block 35 is symmetrically arranged at both ends of the side vibration frame 34. The side vibration frame 34 is rotatably connected to the sliding seat 33. The rotation axis of the side vibration frame 34 extends in the vertical direction. The top of the sliding seat 33 is provided with a rotation drive 37, which is a servo motor. The output end of the rotation drive 37 is equipped with a drive gear. The bottom of the side vibration frame 34 is equipped with a driven gear that meshes with the drive gear. The rotation drive 37 can drive the drive gear to rotate, thereby driving the driven gear and the side vibration frame 34 to rotate.

[0040] When the sliding drive 3 drives the sliding seat 33 to slide with the first vibration block 35, since the first vibration block 35 is symmetrically arranged at both ends of the side vibration frame 34, the two pipes can be slid and impacted simultaneously, and the two pipes can be tested at the same time. Before the sliding drive 3 drives the sliding seat 33 and the first vibration block 35 to complete the sliding impact, the rotation drive 37 can drive the side vibration frame 34 to rotate through the active gear and the driven gear, so that the side vibration frame 34 impacts the outer walls of the two pipes back and forth successively through the first vibration block 35, and the two pipes can be tested for vibration separately. At this time, the staff can judge the tightness of the pipe connection by whether the pipe leaks, thus improving the accuracy and reliability of the test.

[0041] A sliding block 4 is slidably connected to the top side of the machine base 1. The side wall of the sliding block 4 is connected to the side wall of the sliding block 33. The sliding direction of the sliding block 4 is consistent with the sliding direction of the sliding block 33. The sliding block 4 and the sliding block 33 are arranged in a straight line and are distributed on both sides of the lifting base 2. A sliding frame 41 is provided on the top of the sliding block 4. The extension direction of the sliding frame 41 is consistent with the extension direction of the side vibration frame 34. A second vibration block 42 is provided on the side wall of the sliding frame 41. The second vibration block 42 is fixed on the side of the sliding frame 41 near the side vibration frame 34. The shape of the second vibration block 42 is consistent with the shape of the first vibration block 35.

[0042] When the sliding drive 3 drives the sliding seat 33 to slide, since the side wall of the pull slide 4 is connected to the side wall of the sliding seat 33, the sliding seat 33 can drive the pull slide 4 and the pull slide frame 41 to slide back and forth synchronously. This causes the second vibration block 42 to impact and vibrate the side wall of the pipe back and forth, and the first vibration block 35 and the second vibration block 42 to alternately impact and vibrate the two sides of the pipe. This tests the tightness of the pipe connection. Whether the pipe leaks after being subjected to a certain number of impacts and vibrations is determined to determine whether the pipe is tightly connected, thus improving the accuracy and reliability of the test results.

[0043] Reference Figure 3 and Figure 5 The second vibrating blocks 42 are symmetrically arranged at both ends of the sliding frame 41. The bottom of the sliding frame 41 is rotatably connected to the sliding seat 4. A sliding rod 43 is slidably connected to the bottom of the sliding frame 41. The sliding rod 43 is round and rotatably engages with the sliding frame 41. The sliding rod 43 extends vertically. A strip hole 411 is opened on the bottom side of the sliding frame 41. The sliding rod 43 is slidably engaged with the side wall of the strip hole 411. The top end of the sliding rod 43 passes through the strip hole 411 and protrudes from the top side of the sliding frame 41. The side wall of the sliding rod 43 is fixed with... Rotating plate 431 is slidably connected to the side wall of strip hole 411. A connecting rod 44 is provided at the bottom end of sliding rod 43. The connecting rod 44 extends in the horizontal direction. The end of the connecting rod 44 away from sliding rod 43 is located between side vibration frame 34 and sliding seat 33. The top of side vibration frame 34 is threadedly connected to threaded linkage 343. Threaded linkage 343 is a bolt. Threaded linkage 343 is inserted into the top side of the end of connecting rod 44 away from sliding rod 43. The bottom end of threaded linkage 343 is rotatably engaged with the top side of connecting rod 44.

[0044] When the rotating drive 37 drives the side vibration frame 34 to rotate, the side vibration frame 34 pulls the connecting rod 44 and the sliding rod 43 through the threaded linkage 343, thereby causing the sliding rod 43 to pull the sliding frame 41 to rotate. The sliding frame 41 then alternately impacts and vibrates the outer walls of the two pipes through the second vibration block 42. When the first vibration block 35 impacts and vibrates one of the pipes, the second vibration block 42 impacts and vibrates the other pipe. This allows the first vibration block 35 and the second vibration block 42 to alternately test the two pipes simultaneously, improving test efficiency. Furthermore, by conducting tests through diverse vibration methods, the tightness of the pipe connection can be judged by whether there is leakage, thus improving the accuracy and reliability of the test results.

[0045] A first section rod 36 is rotatably connected to the side wall of the sliding seat 33. The rotation axis of the first section rod 36 extends vertically. A second section rod 45 is rotatably connected to the side wall of the pull slide 4. The rotation axis of the second section rod 45 extends vertically. A locking block 46 is rotatably connected to the end of the second section rod 45 away from the pull slide 4. The locking block 46 is rotatably connected to the top side of the end of the second section rod 45 away from the pull slide 4. The locking block 46 is inserted into the first section rod 36. A locking groove 361 is opened on the top side of the first section rod 36. The locking block 46 is inserted into the locking groove 361.

[0046] Multiple fixed seats 11, fixed covers 12, lifting seats 2, and lifting covers 21 can be set on the machine base 1, with the pull slide 4, lifting seats 2, and sliding seats 33 arranged alternately. Two pipes form a group of pipes. When testing pipes, two groups of pipes can be placed simultaneously. A pull slide 4 is set on each of the opposite sides of the sliding seat 33. Rotate the first section rod 36 and the second section rod 45 so that the end of the first section rod 36 away from the sliding seat 33 and the end of the second section rod 45 away from the pull slide 4 are brought closer together. Rotate the locking block 46 so that the locking block 46 is inserted into the locking groove 361, so that the first section rod 36 and the second section rod 45 are locked together by the locking block 46, thereby making the sliding seat 33 and the pull slide 4 mutually connected by the first section rod 36 and the second section rod 45. When connected, the sliding seat 33 is moved, which can drive the other sliding seats 4 to slide. The second vibration block 42 on one of the sliding frames 41 impacts and vibrates one group of pipes, and the second vibration block 42 on the other sliding frame 41 impacts and vibrates the other group of pipes. At the same time, the first vibration block 35 on the side vibration frame 34 impacts the two groups of pipes back and forth through the reciprocating sliding of the sliding seat 33, so that the two groups of pipes can be impacted and vibrated at the same time, and the two groups of pipes can be tested at the same time, which can improve the test efficiency. When it is not necessary to test the two groups of pipes, the locking block 46 can be disengaged from the first section rod 36, thereby separating the first section rod 36 from the second section rod 45, and separating the sliding seat 33 from the sliding seat 4, which allows for flexible adjustment.

[0047] The snap-fit ​​block 46 is T-shaped, and the rotation axis of the snap-fit ​​block 46 extends horizontally. The snap-fit ​​groove 361 is T-shaped, and the shape and size of the snap-fit ​​block 46 are adapted to the shape and size of the snap-fit ​​groove 361. The side wall of the snap-fit ​​block 46 abuts against the groove wall of the snap-fit ​​groove 361.

[0048] When it is necessary to connect the first section 36 and the second section 45, bring the end of the first section 36 away from the sliding seat 33 and the end of the second section 45 away from the pull slide seat 4 closer together, rotate the locking block 46 so that the locking block 46 is inserted into the locking groove 361. After the locking block 46 is inserted into the locking groove 361, when the first section 36 moves, it can drive the second section 45 to move, causing the pull slide seat 4 to slide. Since the locking block 46 is T-shaped, it is not easy to fall out of the locking groove 361 when moving laterally, so that the first section 36 and the second section 45 maintain a stable connection.

[0049] A first pad 351, which is a rubber plate, is inserted into the side wall of the first vibrating block 35. The side wall of the first vibrating block 35 has a groove, and the side wall of the first pad 351 abuts against the groove wall of the first vibrating block 35. A second pad 421, which is a rubber plate, is inserted into the side wall of the second vibrating block 42. The side wall of the second vibrating block 42 has a groove, and the side wall of the second pad 421 abuts against the groove wall of the second vibrating block 42.

[0050] When the first vibrating block 35 and the second vibrating block 42 impact the pipe body, the first pad 351 can protect the first vibrating block 35 and reduce the damage to the first vibrating block 35 during impact. The second pad 421 can protect the second vibrating block 42 and reduce the damage to the second vibrating block 42 during impact. At the same time, it can also reduce the damage to the outer wall of the pipe body due to impact.

[0051] Reference Figure 1 and Figure 3 A rotating rod 341 is fixedly connected to the bottom of the side vibration frame 34. The bottom end of the rotating rod 341 is rotatably connected to the top side of the sliding seat 33. The driven gear is fixed to the side wall of the rotating rod 341. An arc-shaped sliding plate 342 is provided on the bottom side of the side vibration frame 34. The arc-shaped sliding plate 342 extends in the vertical direction. The cross-section of the arc-shaped sliding plate 342 is arranged in an arc-shaped strip. The rotation axis of the arc-shaped sliding plate 342 coincides with the rotation axis of the side vibration frame 34. The bottom side of the arc-shaped sliding plate 342 slides and engages with the top side of the sliding seat 33. The arc-shaped sliding plate 342 slides along the arc direction on the top side of the sliding seat 33.

[0052] When the rotating drive component 37 drives the active gear to rotate, it can drive the driven gear, the rotating rod 341 and the side vibration frame 34 to rotate. When the rotating rod 341 and the side vibration frame 34 rotate, the arc slide plate 342 can guide and support the side vibration frame 34, reducing the force on the rotating rod 341. When the first vibration block 35 drives the tube body to impact and vibrate, the side vibration frame 34 and the rotating rod 341 are subjected to the lateral reaction force from the first rotating block. After the rotating rod 341 is subjected to the impact reaction force, it may bend, which may easily cause the side vibration frame 34 to be unable to rotate. The arc slide plate 342 can share the impact reaction force of the rotating rod 341 and support the side vibration frame 34, making it less likely for the rotating rod 341 to bend, thus protecting the rotating rod 341 and the side vibration frame 34.

[0053] Reference Figure 1 and Figure 2 The side wall of the placement cavity 13 is provided with a slide rail 18, and a vertical plate is fixed to the side wall of the placement cavity 13. The slide rail 18 is installed on the side wall of the vertical plate and extends in the vertical direction. The side wall of the lifting frame 17 is provided with a slider 171. The slider 171 is slidably connected to the slide rail 18. When the lifting frame 17 slides, the slide rail 18 can guide the slider 171 and the lifting frame 17 to reduce the possibility of the lifting frame 17 deviating during sliding.

[0054] The implementation principle of the fluid pipeline vibration testing equipment in this application embodiment is as follows: When a pipeline needs to be tested, the pipeline is installed on the fixed base 11 and the lifting base 2, the pipeline connectors at both ends are sealed, and the water supply pipe 51 is inserted into the pipeline connector. Water is injected into the pipeline connector and the inside of the pipe body. The lifting drive 14 drives the lifting base 2 to move up and down, thereby vibrating the connection position between the pipe body and the pipeline connector to perform a preliminary test on the pipeline. After the preliminary test is completed, the sliding drive 3 drives the sliding base 33 and the first vibration block 35 to slide back and forth, causing the first vibration block 35 to repeatedly impact the side wall of the pipe body, thereby performing a multi-directional vibration test on the pipeline. At this time, the staff can observe whether there is water leakage between the pipe body and the pipeline connector, thereby determining whether the pipeline is tightly connected, which can improve the accuracy of the pipeline vibration test results.

[0055] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
