Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a steel pipe eddy current testing probe and equipment. Background Technology

[0002] Eddy current testing probes and equipment for steel pipes are high-precision testing tools used to detect internal and surface defects in steel pipes. They are widely used in industries such as petroleum, chemical, and machinery manufacturing. They can quickly and accurately detect defects such as cracks, holes, and inclusions in steel pipes, ensuring the quality and safety of the steel pipes. The equipment is easy to operate, has high testing efficiency, and can effectively improve production efficiency, reduce production costs, and ensure the safe operation of industrial production. It is one of the indispensable quality testing equipment in modern industrial production.

[0003] Ultrasonic testing probes and equipment for steel pipes utilize the propagation characteristics of ultrasonic waves within steel pipes to detect defects. The ultrasonic probe emits high-frequency sound waves, which are reflected, refracted, or scattered when they encounter defects within the steel pipe. The probe receives these returned sound wave signals, and the equipment analyzes the location, size, and nature of the defects based on the signal's time, intensity, and waveform changes. This enables non-destructive testing of internal and surface defects in steel pipes, and is widely used to detect cracks, delamination, porosity, and other defects in steel pipes, ensuring the quality of steel pipes.

[0004] In existing technologies, the probes of some devices are not easy to disassemble. When the probe malfunctions or needs to be replaced, the difficulty in disassembling it leads to maintenance personnel spending more time and effort to disassemble and reinstall the probe, reducing maintenance efficiency and increasing maintenance costs. Therefore, a steel pipe eddy current detection probe and device are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a steel pipe eddy current testing probe and equipment, which aims to improve the problem that when the probe fails or needs to be replaced, it is difficult to disassemble, which leads to maintenance personnel spending more time and effort to disassemble and reinstall the probe, reducing maintenance efficiency and increasing maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A steel pipe eddy current testing probe and device includes two tiles, each with two probes fixedly connected inside. A handle is mounted on the outer side of each probe, and a protective cover is fixedly connected to the outer side of the handle. A sliding rod is slidably connected inside the protective cover, and a rotating ring is fixedly connected to the other end of the sliding rod. Multiple connecting posts are fixedly connected to the opposite side of the rotating ring, and a connecting rod is rotatably connected to the other end of each connecting post. A slider is rotatably connected to the other end of each connecting rod, and a slide rail is slidably connected to the inner side of the slider. A clamping block is fixedly connected inside the slider. A buckle is fixedly connected to the adjacent side of the protective cover. A disassembly assembly for easy equipment maintenance is provided at the other end of the handle. As a further description of the above technical solution: The disassembly assembly includes a wire, one end of which is fixedly connected to the opposite side of the handle, and the other end of which is fixedly connected to the outer casing. Two rotating rods are rotatably connected inside the outer casing, and a support block is rotatably connected to the outer side of each of the two rotating rods. A rotating block is fixedly connected to the other end of each of the two rotating rods. Multiple tracks are fixedly connected inside the outer casing, and a moving block is slidably connected to the outer side of each of the multiple tracks. A C-clamp is fixedly connected to the front of each moving block, and a display is mounted on the outer side of the C-clamp. A fixing post is fixedly connected to the adjacent side of the C-clamp, and a spring is fixedly connected to the adjacent side of the fixing post. As a further description of the above technical solution: The protective cover has an arc-shaped groove inside, and the outer side of the slide rod is slidably connected to the inside of the arc-shaped groove. The outer side of the slide rod is in contact with the inner side of the buckle. As a further description of the above technical solution: The outer side of the rotating ring is slidably connected to the inside of the protective cover, and the opposite side of the slide rail is fixedly connected to the inside of the protective cover. As a further description of the above technical solution: The outer side of the rotating ring is slidably connected to the inside of the protective cover, and the opposite side of the slide rail is fixedly connected to the inside of the protective cover. As a further description of the above technical solution: The probe head is slidably connected to the outside of the pipe on one side, and the slider is slidably connected to the inside of the protective cover on the other side. As a further description of the above technical solution: The rear side of the support block is fixedly connected to the inside of the housing, and the rear side of the movable block is slidably connected to the inside of the housing.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the operator pushes the slide bar, which drives the rotating ring to rotate, causing the connecting column and connecting rod to move. This, in turn, drives the slider and clamping block to move up along the slide rail to clamp the probe. The slide bar can be locked into the buckle to fix the probe. The reverse operation can release the probe, making it an independent module. This makes it easy to replace the damaged probe separately without having to return the entire equipment to the factory for repair, which reduces maintenance costs and improves replacement efficiency.

[0008] 2. In this utility model, the operator rotates the rotating rod, causing the rotating block to rotate, which in turn causes the two C-clamps to slide in opposite directions along the track. The springs are compressed and store energy, allowing the C-clamps to expand outward and remove the monitor. The monitor is then placed back in the mounting bracket, and the rotating rod is released. The springs release their elasticity, allowing the components to reset and completing the fixation. This structure enables quick assembly and disassembly, facilitating equipment maintenance and component replacement. Attached Figure Description

[0011] 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.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of a steel pipe eddy current testing probe and device, comprising two tiles 1. The two tiles 1 serve to define the pipe 25 and fix the probe head 12, ensuring stable movement of the device outside the pipe 25 and ensuring that the probe head 12 can stably contact the steel pipe being tested during the testing process, providing basic support for accurate testing. Two probe heads 12 are fixedly connected inside each of the two tiles 1. A handle 2 is installed on the outside of each probe head 12. The handle 2 is installed on the outside of the probe head 12, mainly to provide a gripping point for the operator, facilitating the manipulation of the testing probe and allowing it to flexibly conform to the surface of the pipe 25 for testing.

[0013] A protective cover 3 is fixedly connected to the outer side of the handle 2. The protective cover 3 mainly protects the internal components and provides support for them. A sliding rod 4 is slidably connected inside the protective cover 3. When the sliding rod 4 slides in the arc groove 5, it drives the rotating ring 6 to rotate. This, in turn, through the linkage of the connecting column 7, connecting rod 8, and slider 9, adjusts the position of the clamping block 11. The other end of the sliding rod 4 is fixedly connected to the rotating ring 6. Multiple connecting columns 7 are fixedly connected to the opposite side of the rotating ring 6. The other end of each connecting column 7 is rotatably connected to a connecting rod 8. The other end of the connecting rod 8 is rotatably connected to a slider 9. A slide rail 10 is slidably connected to the inner side of the slider 9. The rotating ring 6, connecting column 7, connecting rod 8, slider 9, and slide rail 10 together form a linkage adjustment mechanism. The rotation of the rotating ring 6 drives the connecting rod 8 to swing through the connecting column 7. The swing of the connecting rod 8 then pushes the slider 9 to slide on the slide rail 10. The sliding of the slider 9 causes the clamping block 11 to move, thereby clamping the probe head 12.

[0014] The slide rail 10 provides a stable guide for the sliding of the slider 9, ensuring that the slider 9 can move smoothly, thereby guaranteeing the accuracy and reliability of the entire adjustment mechanism, enabling the probe head 12 to accurately contact the steel pipe being inspected, and improving the accuracy and stability of the inspection. A clamping block 11 is fixedly connected inside the slider 9. The clamping block 11 is used to fix the probe head 12. A buckle 13 is fixedly connected to the adjacent side of the protective cover 3. After the slide rod 4 moves to a specific position, it embeds into the buckle 13, fixing the position of other components after movement, preventing other components from shifting, and ensuring the stable clamping of the probe head 12 by the clamping block 11. The other end of the handle 2 is equipped with a disassembly component for easy equipment maintenance.

[0015] Reference Figures 3 to 5 The disassembly assembly includes a wire 14. One end of the wire 14 is fixedly connected to the opposite side of the handle 2, and the other end is fixedly connected to the housing 15. The main function of the wire 14 is to transmit the signal detected by the probe 12 to the relevant processing components inside the housing 15 for further processing and analysis of the detection signal, thereby determining the presence of defects in the steel pipe. The housing 15 protects the internal electronic components and mechanical parts, and also provides space for the installation and fixation of these components, making the overall structure of the equipment more compact and stable.

[0016] The housing 15 has two rotating rods 16 internally connected to it. Each rotating rod 16 has a support block 17 rotatably connected to its outer side. The rotating rods 16 and support blocks 17 are designed to enable the rotation of the rotating blocks 18. When maintenance or component replacement is required, the rotating rods 16 are operated to rotate the rotating blocks 18, thereby opening or closing the C-clamp 21, facilitating the disassembly and installation of components such as the display 24. The other end of each rotating rod 16 is fixedly connected to a rotating block 18. When the rotating rods 16 rotate, the rotating blocks 18 move accordingly, pushing or releasing the C-clamp 21, thus controlling the C-clamp 21.

[0017] Multiple tracks 19 are fixedly connected inside the casing 15. Movable blocks 20 are slidably connected to the outer sides of each track 19. The tracks 19 guide the sliding of the movable blocks 20, allowing them to move smoothly. A C-clamp 21 is fixedly connected to the front of the movable block 20. The main function of the C-clamp 21 is to fix the display 24, ensuring its stable installation on the movable block 20. The display 24 is mounted on the outer side of the C-clamp 21. A fixing post 22 is fixedly connected to the adjacent side of the C-clamp 21, and a spring 23 is fixedly connected to the adjacent side of the fixing post 22. The spring 23 can elastically deform and store elastic potential energy when subjected to the opposite force of the C-clamp 21. After the movement process is completed, the spring 23 can drive other components to return to their original positions.

[0018] Reference Figure 1 , Figure 2 , Figure 4 The protective cover 3 has an arc-shaped groove 5 inside. The outer side of the slide rod 4 is slidably connected to the inside of the arc-shaped groove 5. The arc-shaped groove 5 is the sliding direction of the slide rod 4, and its shape and size match the outer side of the slide rod 4. When the slide rod 4 slides in the arc-shaped groove 5, the arc-shaped groove 5 can guide the slide rod 4 to move along a predetermined trajectory. The outer side of the slide rod 4 contacts the inner side of the buckle 13. The outer side of the rotating ring 6 is slidably connected to the inside of the protective cover 3. When the slide rod 4 slides in the arc-shaped groove 5, it will drive the rotating ring 6 to rotate. The opposite side of the slide rail 10 is fixedly connected to the inside of the protective cover 3.

[0019] The adjacent side of the clamping block 11 is installed on the outside of the probe head 12, and the adjacent sides of the two tiles 1 are slidably connected to the pipe 25. The adjacent side of the probe head 12 is slidably connected to the outside of the pipe 25, and the distant side of the slider 9 is slidably connected to the inside of the protective cover 3. When the rotating ring 6 rotates, the slider 9 will slide on the slide rail 10 through the linkage of the connecting column 7 and the connecting rod 8. The sliding of the slider 9 drives the clamping block 11 to move, thereby realizing the adjustment of the position of the probe head 12. The rear side of the support block 17 is fixedly connected to the inside of the housing 15, and the rear side of the moving block 20 is slidably connected to the inside of the housing 15. The distant side of the C-clamp 21 is slidably connected to the inside of the housing 15, and the outer side of the rotating block 18 is in contact with the adjacent side of the C-clamp 21. When the rotating block 18 pushes the C-clamp 21, the C-clamp 21 will release the display 24, making it convenient to disassemble or replace the display 24. When the rotating block 18 releases the C-clamp 21, the spring 23 provides elastic restoring force, enabling the C-clamp 21 to automatically clamp the display 24, ensuring that the display 24 is stably mounted on the housing 15.

[0020] Working principle: When the operator pushes the slide bar 4, the slide bar 4 begins to move and drives the rotating ring 6 to rotate inside the protective cover 3. The rotation of the rotating ring 6 causes the multiple connecting posts 7 fixedly connected to it to move, which in turn drives the connecting rod 8 to move. The movement of the connecting rod 8 causes the slider 9 to drive the clamping block 11 to slide upward in the direction of the slide rail 10, thereby clamping the probe head 12. At this time, the slide bar 4 is inserted into the buckle 13 to complete the fixation of the probe head 12. The slide bar 4 is removed and pushed in the opposite direction to release the probe head 12, making the probe head 12 an independent module. When it is worn or damaged, only the individual probe head 12 needs to be replaced, instead of returning the entire testing equipment to the factory for repair. This reduces maintenance costs and simplifies operation, improving replacement efficiency.

[0021] The operator rotates the rotating rod 16, which in turn rotates the rotating block 18. The rotation of the rotating block 18 causes the two C-clamps 21 to slide in opposite directions under the constraint of the track 19. At this time, the spring 23 undergoes elastic deformation and stores elastic potential energy. When the C-clamps 21 expand outward, the display 24 can be removed. The display 24 is then put back and the rotating rod 16 is released. The elastic potential energy stored in the spring 23 is released, causing a series of components to return to their original positions, thus completing the fixation of the display 24. This achieves the effect of quick disassembly, making equipment maintenance and repair faster and component replacement more convenient.

[0022] 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.
