Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing detection technology, and in particular to a penetration testing device for testing the seals of pressure pipeline welds. Background Technology
[0002] Pressure pipelines are widely used in petroleum, chemical, energy, and many other fields. The sealing performance of their welds directly affects production safety and operational stability. Leaks in pipeline welds can lead to serious safety accidents, causing huge economic losses and environmental pollution. With the continuous expansion of industrial production and increasingly stringent requirements for pipeline transportation safety, the loading and unloading of pipelines, as the starting and ending steps of the testing process, directly impacts the pace of the entire testing operation in terms of ease of operation and efficiency. Traditional testing equipment has significant shortcomings in pipeline loading and unloading, making it difficult to meet the demands of modern industrial rapid and efficient production. Therefore, permeation equipment that facilitates pipeline loading and unloading for sealing testing is of paramount practical importance.
[0003] Traditional penetrant testing equipment for pressure pipeline weld seal inspection typically employs a combination of manual handling and simple mounting frames for pipeline fixing and transportation. The pipeline is manually moved to the inspection area and placed on the mounting frame, which is generally a simple frame structure and fixed by bolts or clamps. During the inspection process, the pipeline position is manually adjusted to align the inspection head with the weld.
[0004] However, existing technologies suffer from the problem of extremely inconvenient pipe loading and unloading. The process of moving and fixing the pipe to the testing equipment relies entirely on manual operation, which is not only labor-intensive but also inefficient. Furthermore, manual operation makes it difficult to ensure the accuracy and consistency of pipe placement, leading to difficulties in aligning the testing head with the pipe weld, thus affecting the accuracy and reliability of the testing results. After the testing is completed, the process of removing the pipe from the testing equipment is equally cumbersome, affecting the overall efficiency of the testing work. To address these issues, a permeation device for testing the seal of pressure pipe welds is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a penetration testing device for pressure pipeline weld seal inspection, which aims to improve the problem that the process of transporting and fixing the pipeline to the testing device in the prior art relies entirely on manual operation, which not only consumes a lot of manpower but is also inefficient.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A penetrant testing device for pressure pipeline weld seal inspection includes a workbench, a support frame fixedly connected to the top of the workbench, a guide column one fixedly connected inside the support frame, a guide column two fixedly connected inside the support frame, a fixed frame fixedly connected to the top of the workbench, a hydraulic cylinder fixedly connected to the top of the fixed frame, a connecting block fixedly connected to the output end of the hydraulic cylinder, a detection component provided at the bottom of the connecting block, and a pick-and-place component provided inside the support frame.
[0008] The pick-and-place assembly includes a cylinder one, one side of which is fixedly connected to the inside of the support frame. A slider is fixedly connected to the output end of the cylinder one. The slider is slidably connected to the outer wall of the guide post two. A cylinder two is fixedly connected to one side of the slider. A slide plate is fixedly connected to the output end of the cylinder two. A clamp is provided on one side of the slide plate. A slide rail is fixedly connected to one side of the cylinder two. The slide plate is slidably connected to the outer wall of the slide rail.
[0009] As a further description of the above technical solution:
[0010] The detection component includes a detection head, the top of which is fixedly connected to the bottom of the connecting block.
[0011] As a further description of the above technical solution:
[0012] A motor is fixedly connected to the bottom of the workbench, and a turntable is fixedly connected to the output end of the motor.
[0013] As a further description of the above technical solution:
[0014] A support block is fixedly connected to the top of the turntable, and the turntable is rotatably connected to the top of the workbench.
[0015] As a further description of the above technical solution:
[0016] A support base is fixedly connected to the top of the support block, and an arc-shaped plate is provided inside the support base.
[0017] As a further description of the above technical solution:
[0018] A clamping plate is fixedly connected to the bottom of the arc-shaped plate, and the clamping plate is slidably connected inside the support base.
[0019] As a further description of the above technical solution:
[0020] A connecting column is fixedly connected to one side of the clamping plate, and the connecting column is slidably connected inside the support base.
[0021] As a further description of the above technical solution:
[0022] A spring is fitted on the outer wall of the connecting column, and the two ends of the spring are fixedly connected to the support base and the clamping plate, respectively.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, starting cylinder one pushes the slider to move, the slider drives cylinder two, which in turn drives the slide plate and clamp to move above the support base. Then, cylinder two drives the slide plate to descend, and the clamp places the pipe in the support base and fixes it, thus realizing the effect of automated loading and unloading. This solves the problem that the process of transporting and fixing the pipe to the testing equipment is entirely dependent on manual operation, which not only consumes a lot of manpower but is also inefficient, thereby improving the testing efficiency.
[0025] 2. In this invention, when the pipe is placed inside the support, it contacts the arc-shaped plate. The arc-shaped plate moves the bottom clamping plate, which causes the spring to slide and contract within the support. Subsequently, the spring, relying on its own elasticity, pushes the clamping plate to tightly fit against the outer wall of the pipe, achieving an adaptive fixing effect according to the pipe size. This solves the problem that traditional fixing methods are difficult to adapt to pipes of different sizes, thereby improving the applicability of the device during testing.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 An embodiment of this utility model provides a penetration testing device for pressure pipeline weld seal inspection, including a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, a guide column 3 fixedly connected inside the support frame 2, a guide column 6 fixedly connected inside the support frame 2, a fixed frame 11 fixedly connected to the top of the workbench 1, a hydraulic cylinder 12 fixedly connected to the top of the fixed frame 11, a connecting block 13 fixedly connected to the output end of the hydraulic cylinder 12, a detection component provided at the bottom of the connecting block 13, and a pick-and-place component provided inside the support frame 2;
[0034] The pick-and-place assembly includes a cylinder 4, one side of which is fixedly connected to the inside of the support frame 2. A slider 5 is fixedly connected to the output end of the cylinder 4. The slider 5 is slidably connected to the outer wall of the guide post 6. The movement of the slider 5 drives the cylinder 7, thereby moving the slide plate 8 and the clamp 10 together. A cylinder 7 is fixedly connected to one side of the slider 5. A slide plate 8 is fixedly connected to the output end of the cylinder 7. A clamp 10 is provided on one side of the slide plate 8. The clamp 10 can firmly clamp the pipe for pick-and-place operations. A slide rail 9 is fixedly connected to one side of the cylinder 7. The slide plate 8 is slidably connected to the outer wall of the slide rail 9. The detection assembly includes a detection head 14. The top of the detection head 14 is fixedly connected to the bottom of the connecting block 13. When the output end of the hydraulic cylinder 12 drives the connecting block 13 to move, the detection head 14 at the bottom of the connecting block 13 will insert into the pipe and start the penetration test. A motor 15 is fixedly connected to the bottom of the workbench 1. A turntable 16 is fixedly connected to the output end of the motor 15. A support block 17 is fixedly connected to the top of the turntable 16. The turntable 16 is rotatably connected to the top of the workbench 1.
[0035] Specifically, when using the penetrant testing equipment for pressure pipeline weld seals, the pipeline is first clamped by the clamp 10. Next, the output end of cylinder 4 drives the slider 5 to move. The movement of the slider 5 drives cylinder 7 on one side, thereby moving the slide plate 8 and the clamp 10 together. The slide plate 8 moves along the guide rail of the equipment towards one of the support seats 18 on the top of the workbench 1. At this time, the output end of cylinder 7 continues to drive the slide plate 8 to slide in the plane, so that the clamp 10 completes the positioning. Finally, the pipeline is placed inside the support seat 18 for fixation. After the pipeline is placed, the output end of motor 15 drives the turntable 16 to rotate. The rotation of the turntable 16 drives the pipeline to rotate along the circumferential trajectory through the multiple support seats 18 connected to it. Each support base 18 is driven by the motor 15, causing the pipe to rotate and move below the detection head 14. At this time, the output end of the hydraulic cylinder 12 drives the connecting block 13 to move. The movement of the connecting block 13 causes the detection head 14 to insert into the pipe and begin penetration testing. After the test is completed, the motor 15 drives the turntable 16 to rotate, bringing the support base 18 back below the clamp 10. The clamp 10 then holds the pipe and removes the qualified pipe, completing the entire testing process. In this way, the equipment can effectively realize the loading and unloading of pipes while ensuring testing efficiency and accuracy.
[0036] Reference Figure 1 and Figure 4 The top of the support block 17 is fixedly connected to the support base 18. The support base 18 has an arc plate 19 inside. The bottom of the arc plate 19 is fixedly connected to the clamping plate 20. The cooperation between the arc plate 19 and the clamping plate 20 can be automatically adjusted according to the diameter of the pipe. The clamping plate 20 is slidably connected inside the support base 18. A connecting column 21 is fixedly connected to one side of the clamping plate 20. The connecting column 21 is slidably connected inside the support base 18. A spring 22 is sleeved on the outer wall of the connecting column 21. The two ends of the spring 22 are fixedly connected to the support base 18 and the clamping plate 20 respectively.
[0037] Specifically, when the pipe is placed inside the support base 18, the pipe will contact the arc-shaped plate 19 inside the support base 18. The design of the arc-shaped plate 19 allows the clamping plate 20 inside the support base 18 to move. After the clamping plate 20 is subjected to force, it drives the connecting column 21 to slide inside the support base 18, thereby fixing the pipe. The spring 22 on one side of the clamping plate 20 is compressed during the process of the clamping plate 20 being subjected to force. Through the rebound force of the spring 22, the clamping plate 20 can fit tightly against the outer wall of the pipe and fix it firmly. Through the elastic action of the spring 22, even if there is a slight difference in the outer diameter of the pipe, the clamping plate 20 can automatically adjust according to the pipe of different sizes, ensuring that pipes of different sizes can be firmly clamped.
[0038] Working principle: When using this penetrant testing equipment for pressure pipeline weld seal inspection, the pipeline is first clamped by clamp 10. Then, the output end of cylinder 4 drives the slider 5 to move. Slider 5 drives cylinder 7 on one side to move. Cylinder 7 drives the slide plate 8 and clamp 10 on one side to move above one of the support seats 18 on the top of the worktable 1. At this time, the output end of cylinder 7 drives the slide plate 8 to move. The slide plate 8, under force, drives the clamp 10 on one side to descend, so that the clamp 10 places the pipeline into the support seat 18 for fixation. After placement, the output of motor 15 drives turntable 16 to rotate, which in turn drives multiple support seats 18 on top to rotate. This causes the support seats 18 to move the internal pipes to below the detection head 14. Then, the output of hydraulic cylinder 12 drives connecting block 13 to move, and connecting block 13 drives detection head 14 to be inserted into the pipe for penetration testing. After the test is completed, motor 15 drives turntable 16 to rotate support seats 18 to below clamp 10, and then clamp 10 is used to remove the tested pipe, thus facilitating the loading and unloading of pipes.
[0039] When the pipe is placed inside the support base 18, the pipe will come into contact with the arc plate 19 inside the support base 18, causing the arc plate 19 to move the clamping plate 20 at the bottom. The clamping plate 20 is subjected to force, causing the connecting column 21 connected on one side to slide inside the support base 18. At the same time, the clamping plate 20 compresses the spring 22 on one side, causing it to contract. Through the elasticity of the spring 22 itself, the clamping plate 20 can be tightly fitted to the outer wall of the pipe to fix it, thereby achieving the effect of effectively fixing pipes of different sizes.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
