Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a tooling for a wall thickness detection probe. Background Technology

[0002] Wall thickness corrosion testing generally refers to the online or periodic measurement of the remaining wall thickness of in-use metal equipment to understand the corrosion status of the equipment, estimate its service life, determine safe operating parameters, and provide a reference for periodic inspection and maintenance. This is particularly important for pressure vessels, pressure pipelines, and boilers that withstand long-term pressure and contain various toxic, harmful, and corrosive media, and is currently a required inspection item for the periodic inspection of pressure-bearing special equipment. With the rapid increase in the number of various containers, pipelines, and other equipment, more and higher requirements are being placed on wall thickness corrosion testing.

[0003] Currently, commonly used methods for measuring the wall thickness of in-use equipment include ultrasonic testing, magnetic flux leakage testing, and eddy current testing. Among these, ultrasonic testing is the most widely used due to its advantages such as small equipment size, low weight, high detection sensitivity, simple operation, and high safety. It is mainly divided into piezoelectric sensing ultrasonic testing and electromagnetic sensing ultrasonic testing. In actual testing, the inspector holds the instrument and moves to the vicinity of the selected thickness measurement area to take measurements and record the values. This method requires the inspector to manually measure close to the measurement area. In reality, due to space, temperature, and environmental factors, it is difficult for inspectors to reach the necessary measurement areas. Furthermore, this intermittent measurement method cannot reflect the real-time corrosion status of key parts of the equipment, nor can it reveal occasional corrosion in these areas.

[0004] In the development of wall thickness monitoring systems, the installation and fixation of the wall thickness detection probe, the coupling between the probe and the equipment surface, and the heat insulation and protection of the probe when detecting high-temperature equipment surfaces are all important factors affecting the overall system performance. Existing patent documents related to wall thickness monitoring rarely provide detailed and clear descriptions of the installation and fixation methods for the detection probes. Installation and disassembly are often cumbersome, or the coupling between the probe and the detection surface is difficult to guarantee, especially for high-temperature equipment surfaces, where probe protection is challenging. Furthermore, existing technologies typically do not consider whether the equipment material is ferromagnetic when installing the detection equipment, usually using metal clamps and bolts for fixation. This method has requirements on the outer diameter of the equipment. For high-temperature equipment surfaces, waveguides or waveguides are commonly used to transmit acoustic signals, and the fixation method is still often metal clamps and bolts. There is little mention of probe coupling methods, especially regarding the heat insulation and protection of wall thickness detection probes for high-temperature equipment.

[0005] Therefore, there is currently a lack of a universal probe fixture that can be used for both ferromagnetic and non-ferromagnetic materials, has low requirements for the outer diameter of the equipment, and can ensure effective fixation and coupling of the detection probe.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] Example 1:

[0051] like Figure 1 , Figure 2 , Figure 3 As shown, the wall thickness detection probe fixture includes a magnetic base 1, a protective tube 2, a control box 3, a drive component 4, a detection probe 5, a coupling agent supply assembly 6, and an electrical control module 7. The magnetic base 1 is detachably connected to the bottom of the protective tube 2, the control box 3 is detachably connected to the top of the protective tube 2, the fixed end of the drive component 4 is connected inside the control box 3, and the telescopic end of the drive component 4 is detachably connected to the detection probe 5. The drive component 4 and the detection probe 5 are located inside the protective tube 2. The coupling agent supply assembly 6 is connected to and communicates with the side of the protective tube 2. The electrical control module 7 is connected inside the control box 3 and is electrically connected to the drive component 4 and the coupling agent supply assembly 6.

[0052] like Figure 4 As shown, the magnetic base 1 includes a magnetic switch 11 on its side. When the magnetic switch 11 is turned on, the magnetic base 1 has a magnetic force that allows it to adhere to the pipe being tested. The magnetic base 1 has a detection hole 12 in its center. The bottom surface of the magnetic base 1 also includes an arc-shaped notch along the horizontal direction, which facilitates the magnetic base 1 to fit snugly against the pipe being tested 9.

[0053] like Figure 5 As shown, the protective tube 2 is a cylindrical pipe with openings at both the top and bottom. A rectangular plate 21 is connected to the bottom of the protective tube 2, and the rectangular plate 21 is bolted to the magnetic base 1, creating a detachable structure. Multiple fixing lugs 22 are connected to both sides of the bottom of the protective tube 2. These lugs have through holes and slots, allowing cable ties to secure the fixture to the equipment or the pipe under test 9. A supply tube 23 is also connected to one side of the bottom of the protective tube 2, which is used to connect to the coupling agent supply assembly 6. A fixing plate 24 is also connected to the side of the protective tube 2, which is used to install the coupling agent supply assembly 6. The top of the protective tube 2 includes multiple locking holes 25, which are used to connect to the control box 3 using bolts or screws.

[0054] The protective tube 2 can effectively fix and support other components, and together with the control box 3, it can protect the internal detection probe 5, electric push rod, and electric control module 7.

[0055] like Figure 6 , Figure 7 As shown, the control box 3 includes a box body 31 and a box cover 32. The box body 31 has a square cavity structure, and the top opening of the box body 31 is detachably connected to the box cover 32 by bolts. A cylindrical tube 33 extends downward from the bottom surface of the box body 31. The radial direction of the cylindrical tube 33 includes multiple connecting holes 34. The connecting holes 34 are used to align with the locking holes 25 and then connect with bolts or screws to realize the connection between the control box 3 and the protective tube 2. The bottom surface of the box body 31 also includes multiple control fixing holes 35, and the side surface of the box body 31 also has multiple functional holes 36. The functional holes 36 and control fixing holes 35 are used for functional expansion and control fixing. Specifically, the functional holes 36 are used to install and fix wireless communication modules or communication antennas 37, or to fix other components inside the control box 3 by fixing pins or screws. The control fixing holes 35 are used to fix the controls inside the control box 3 by screws to ensure the stability of the components inside the control box 3. The control box 3 is provided with control box functional holes and control fixing holes, which can be used to add other modules to realize other additional detection capabilities and expand the tooling utility.

[0056] like Figure 8 As shown, combined with Figure 3As shown, the driving component 4 in this embodiment is an electric push rod, which is aligned with the central axis of the protective tube 2. Multiple connecting plates are connected to the top side of the electric push rod, and these connecting plates are connected to the control fixing holes 35 via screws. A detection probe 5 is installed at the moving end of the electric push rod. The detection probe 5 can be connected to the electric push rod via a threaded structure, and the type of detection probe 5 can be selected according to the actual detection situation. When the electric push rod is not powered on, it is in a retracted state. At this time, the detection probe 5 does not contact the detection surface and maintains a certain distance. This provides heat insulation protection for the detection probe 5, especially when the surface temperature of the equipment is high.

[0057] like Figure 7 As shown, the electronic control module 7 can be fixed in the control box 3 through the functional hole 36 and / or the control fixing hole 35. The electronic control module 7 mainly includes a battery and electronic control components. The detection probe parameters, the energizing time and energizing interval of the electric actuator and the coupling agent supply pump 62 can be set on the electronic control module 7. The electronic control module 7 can also supply power according to the settings to power the electric actuator and the coupling agent supply pump 62.

[0058] In the above embodiments, if the material of the equipment to be tested is a ferromagnetic material, the detection probe 5 is selected according to the surface temperature of the equipment. The detection probe 5 is connected to the drive component 4, and the drive component 4 is fixed on the control box 3. Coupling agent is added to the coupling agent storage bottle 61. After adjusting the plumbness of the adjustment frame 64, it is fixed to the fixing plate 24. The parameters of the detection probe 5, the energizing time of the drive component 4 and the coupling agent supply pump 62 are set on the electrical control module 7. The wall thickness detection probe fixture is placed on the part to be tested. The magnetic switch 11 of the magnetic base 1 is turned on, and the device is magnetically installed at the detection position of the pipe 9 to be tested. The electrical control module 7 is powered according to the settings. After the coupling agent supply pump 62 is energized, the coupling agent is supplied to the detection part through the coupling agent supply pipe 23. The drive component 4 is in a retracted state when it is not energized. At this time, the detection probe 5 does not contact the detection surface and maintains a certain distance. After being energized, the bottom end of the drive component 4 extends, pushing the detection probe 5 toward the surface of the detection part, and at the same time, it contacts the coupling agent and the detection surface to achieve coupling and detection.

[0059] When the material of the equipment to be tested is a non-ferromagnetic material, the decision to remove the magnetic base 1 can be made based on the condition of the surface of the equipment being tested. If the curvature of the part being tested is very small, and the bottom surface of the magnetic base 1 is difficult to fit well with the surface of the part being tested, the magnetic base 1 can be removed so that the bottom surface of the protective tube 2 contacts the surface being tested. Alternatively, if the part being tested has a heat insulation layer or protective layer of a certain thickness, and the overall height of the tooling affects the function of the heat insulation layer or protective layer, the magnetic base 1 can be removed to reduce the height of the tooling and reduce the impact on the function of the heat insulation layer or protective layer.

[0060] If the magnetic base 1 is removed, the device is fixed to the equipment using a slipknot cable tie via the fixing lug 22, and the test is performed in the manner described above.

[0061] For situations where the surface temperature of the device being tested is high, a high-temperature coupling agent is added to the coupling agent storage bottle 61, a high-temperature resistant detection probe 5 is selected, and the driving component 4 has an isolation distance from the surface when the power is off, which can achieve heat insulation protection for the detection probe 5.

[0062] When the surface of the equipment being tested needs to be covered with a heat insulation layer, the area of ​​the heat insulation layer that needs to be removed is small when installing and removing the wall thickness detection probe fixture. The removal can be completed by rotating and closing the magnetic base 1 or opening the buckle strap. When it is necessary to adjust the device parameters or adjust and replace the detection probe 5, the cover 32 can be removed and the corresponding operation can be completed in the control box 3.

[0063] In this embodiment, the installation is simple and the requirements for the installation location are low. The magnetic base 1 is easy to operate. For ferromagnetic materials, magnetic suction installation can be used. For non-ferromagnetic materials, the magnetic base 1 can be removed and fixed with cable ties. Alternatively, both magnetic suction and cable ties can be used for fixing. It is flexible in use and the outer diameter of the equipment being tested has few restrictions on the installation. The overall size of the equipment is small. When there is a heat insulation layer on the surface of the equipment, the area of ​​the heat insulation layer that needs to be removed is small, and the impact on the heat insulation layer is small.

[0064] It can be used in conjunction with existing data collection and analysis equipment to achieve online wall thickness monitoring, reduce manual inspection costs and risks, obtain real-time inspection data, and ensure the overall safety of the equipment.

[0065] Example 2:

[0066] like Figure 9 , Figure 10 As shown, the coupling agent supply assembly 6 includes a coupling agent storage bottle 61, a coupling agent supply pump 62, a mounting bracket 63, and an adjusting bracket 64. Two mounting brackets 63 are arranged parallel to each other vertically, and one side of each mounting bracket 63 is fixedly connected to the adjusting bracket 64, which can be welded. Each mounting bracket 63 includes two mounting holes, in which the coupling agent storage bottle 61 and the coupling agent supply pump 62 are fixedly connected respectively. The coupling agent storage bottle 61 and the coupling agent supply pump 62 are connected via pipes, and the coupling agent supply pump 62 is connected to the supply pipe 23 via pipes.

[0067] The adjusting frame 64 is vertically connected to the mounting bracket 63. Each end of the adjusting frame 64 has two adjusting holes. The side of the protective tube 2 is also connected to the fixing plate 24. The fixing plate 24 has a disc-shaped structure and includes multiple fixing holes along the circumference. The adjusting holes and fixing holes are connected by bolts, thereby realizing the connection between the entire coupling agent supply assembly 6 and the protective tube 2. At the same time, the installation angle of the coupling agent storage bottle 61 and the coupling agent supply pump 62 can be adjusted according to the connection between the adjusting holes and different fixing holes.

[0068] A coupling agent reservoir 61 and a coupling agent supply pump 62 are provided to supply coupling agent to the detection site when detection is required. Appropriate coupling agents are selected for different detection surfaces to ensure the coupling capability between the detection probe 5 and the detection site, thereby improving detection accuracy. The installation angle of the coupling agent reservoir 61 and the coupling agent supply pump 62 can also be adjusted via the fixing plate 24 to ensure the coupling agent supply capacity.

[0069] Example 3:

[0070] like Figure 11 As shown, when wireless remote control or wireless transmission of detection data is required for the detection probe, a wireless communication module is added. The wireless communication module is fixedly installed inside the control box 3, secured via the functional hole 36. When the probe needs to be fixed at a certain detection location for a long period and the battery is insufficient, a solar module 8 can be added to achieve long-term self-powered operation. The solar module 8 includes a solar panel and a battery pack. The solar module 8 is connected to the electronic control module 7 via a cable.

[0071] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
