Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing systems, specifically to a high-energy X-ray nondestructive testing system. Background Technology

[0002] After the production of a single batch or individual concrete column, sampling and inspection are required. This includes checking the internal structure and defects of the concrete column. The health of the concrete structure is directly related to the safety of the building. The inspection can detect potential defects, such as cracks, voids or material deterioration, to prevent accidents during use. Through experimental data, the corresponding experimental parameters can be adjusted to make the concrete column meet different requirements, thus enabling the concrete column to be used in different application scenarios.

[0003] For laboratory and field applications, the target object is a concrete cylinder with a diameter of approximately 1m. Non-destructive testing (NDT) techniques are used to image and inspect the internal structure and defects. However, due to limitations in the activity of gamma or neutron sources and stringent environmental impact assessment requirements, using radioactive sources as samples is unsuitable. Furthermore, neutron generator-based imaging technology is currently not mature enough and is limited by imaging accuracy and time, making it unsuitable for field use. Additionally, it cannot inspect concrete cylinders of different sizes, reducing the equipment's practicality. Utility Model Content

Two transmission blocks are threaded onto each double-ended lead screw. A pressure cylinder is hinged to the upper end of each transmission block.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] like Figures 1 to 7 As shown, this embodiment proposes a high-energy X-ray non-destructive testing system, including a high-energy X-ray accelerator head 11, a flat panel linear array imaging unit 12 for converting X-rays into electrical signals, a computer image processing system for visualizing electrical signals, a monitoring system for full coverage of the operating area, a mechanical system 13 for clamping and controlling the workpiece, an electrical control system and a high-voltage and control module 14 for precise control in conjunction with the mechanical system 13.

[0034] The high voltage and control module 14 includes a high voltage power supply, control circuit, feedback system, safety protection mechanism and user interface. The high voltage power supply can convert the input AC power into the required high voltage DC power through a transformer and rectifier for use by the electron gun and acceleration chamber.

[0035] The control circuit contains a microcontroller or digital signal processor (DSP) for real-time monitoring and regulation of the power supply output voltage and current, and can dynamically adjust the high voltage output according to operational requirements.

[0036] Accelerators are typically equipped with feedback mechanisms, such as voltage and current sensors, to monitor their operating status in real time. These sensors feed data back to the control module to ensure the stability and safety of the high-voltage power supply output.

[0037] To prevent high-voltage failures, the system is designed with multiple safety protection measures, such as overvoltage protection, short-circuit protection, and temperature monitoring. Upon detecting any abnormality, the control module will immediately cut off the high-voltage power supply to ensure the safety of the equipment and operators.

[0038] The control module is also usually equipped with a user interface, which allows operators to easily set and adjust the accelerator's operating parameters, such as output energy and operating mode, via a touch screen or buttons.

[0039] In summary, the high voltage and control module 14 features switchable energy of 9MeV / 6MeV, compact structure, simple operation, low radiation leakage rate, safe and reliable operation, and stable performance, and can provide better quality penetration imaging effect.

[0040] The image processing system mainly performs functions such as image acquisition, image storage, image processing, image evaluation, and image printing.

[0041] The flat panel linear array imaging unit 12 includes a flat panel imaging unit 121 and a linear array imaging unit 122, and a shielding cover 123 is disposed on the outside of the flat panel imaging unit 121 and the linear array imaging unit 122.

[0042] Through the main features of high resolution, low noise, large dynamic range and high transmission rate of the flat panel imaging unit 121 and the linear array imaging unit 122, users can be provided with clearer and more reliable image information.

[0043] Several gratings 15 are respectively fixedly connected to the shielding cover 123 and the high-energy X-ray accelerator head 11 on the opposite side;

[0044] The grating 15 is used to protect the flat linear array imaging unit 12 and the high-energy X-ray accelerator head 11 inside the shielding cover 123, preventing damage to the equipment or people.

[0045] Mechanical system 13 includes linear guide rail 131, which is set between high-energy X-ray accelerator head 11 and flat panel linear array imaging unit 12. Turntable 132 is slidably connected to linear guide rail 131. Lifting carriage 133 is fixedly connected to turntable 132. Clamping assembly capable of clamping workpieces of different diameters is connected to lifting carriage 133.

[0046] The linear guide 131, turntable 132, and lifting platform 133 enable the clamped workpiece to move, rotate, and lift, allowing the X-rays generated by the high-energy X-ray accelerator head to irradiate different areas of the concrete cylinder, thereby improving the experimental data of the concrete cylinder and reducing the impact of high-energy X-ray radiation on the surrounding environment. At the same time, by using the high-energy X-ray accelerator head 11 in conjunction with the flat panel linear array imaging unit 12, real-time transmission images of the interior of the object under test can be observed, thereby measuring information such as the size and length of the object inside. Simultaneously, the image processing system completes the storage and processing of the images to improve the image clarity and ensure the accuracy of the evaluation.

[0047] Secondly, the mechanical system 13 enables imaging inspection of the internal structure and defects of concrete cylinders with different diameters and lengths, thus improving the practicality of the equipment.

[0048] like Figures 3-7 As shown, the clamping assembly includes a support plate 21, which is detachably and fixedly connected to the upper side of the lifting platform 133. Several universal balls 22 are fixedly connected to the upper side of the support plate 21. The ends of the universal balls 22 away from the support plate 21 abut against two tension plates 23. The first mounting plate 241 and the second mounting plate 242 are fixedly connected to the lower side of the tension plate 23. The double-ended screw 25 is rotatably connected to the first mounting plate 241 and the second mounting plate 242. The limiting rod 26 is fixedly connected to the upper side of the double-ended screw 25. The double-ended screw 25 is threadedly connected to two transmission blocks 27. The upper end of each transmission block 27 is hinged to a pressure cylinder 28. The end of the pressure cylinder 28 away from the transmission block 27 is hinged to a support frame 29. Each support frame 29 is hinged to the tension plate 23.

[0049] By precisely controlling the rotation of the double-ended lead screw 25, the opening angle of the two support frames 29 on the same side can be adjusted, so that concrete cylinders of different diameters can be clamped. Manual adjustment is also possible. In addition, several universal balls 22 can support the two tension plates 23, making the two tension plates 23 more stable when sliding, thus improving the practicality of the equipment.

[0050] The limiting plate 210 is slidably connected between the two tension plates 23;

[0051] A displacement assembly for driving the two side tension plates 23 and the limiting plate 210 to slide relative to each other is connected to the lower side of the limiting plate 210;

[0052] The shifting component can adjust the relative movement distance between the two stretching plates 23 and the limiting plate 210, so that the distance between the two support frames 29 on each stretching plate 23 changes, thereby enabling several support frames 29 to support and clamp workpieces of different shaft lengths, and enabling workpieces of different lengths to be clamped, thus improving the practicality of the equipment.

[0053] The servo motor 211 is fixedly connected to the first mounting plate 241, and the drive shaft of the servo motor 211 is fixedly connected to the adjacent double-ended lead screw 25.

[0054] The rotation of the double-ended lead screw 25 can be precisely controlled by the servo motor 211.

[0055] like Figures 5-7 As shown, the slot 291 is formed on the support frame 29, the adjusting screw 31 is rotatably connected to the inner wall of the slot 291, the adjusting screw 31 is threadedly connected to the adjusting block 32, and the adjusting block 32 abuts against the inner wall of the slot 291.

[0056] The adjusting block 32 is hinged to the end of the pressure cylinder 28 away from the transmission block 27;

[0057] The pressure cylinder 28 provides shock absorption and buffering for the workpiece suspended on the support frame 29, thereby protecting the support frame 29. Then, the adjusting screw 31 is rotated to adjust the position of the adjusting block 32 on the adjusting screw 31, thereby adjusting the opening angle between the two support frames 29, so that the support frame 29 can accommodate workpieces of different diameters, thus improving the practicality of the equipment.

[0058] like Figures 3-4 As shown, the clearance slot 292 is formed on the support frame 29;

[0059] This makes it convenient for workers to adjust the adjusting screw 31.

[0060] like Figure 2 and Figure 4 As shown, the side of the support frame 29 away from the adjusting screw 31 is fixedly connected to the locking pad 33;

[0061] The positioning pad 33 reduces wear between the support frame 29 and the workpiece, thereby increasing the service life of the support frame 29. Furthermore, when the workpiece is lowered by the hoisting equipment, the positioning pad 33 can reduce the impact of the workpiece on the support frame 29.

[0062] like Figure 5 and Figure 7 As shown, the displacement assembly includes a displacement cylinder 41, which is fixedly connected to the lower side of the limiting plate 210. The telescopic shaft of the displacement cylinder 41 is fixedly connected to the linkage block 42. Two linkage plates 43 are hinged to the linkage block 42, and each linkage plate 43 is hinged to the lower side of the adjacent stretching plate 23.

[0063] By resetting the telescopic shaft of the shift cylinder 41, the linkage block 42 can be moved towards the limiting plate 210, thereby causing the tension plates 23 on both sides to slide. That is, by working the shift cylinder 41, the distance between the two tension plates 23 can be directly controlled, so that the support frame 29 connected to the tension plate 23 can clamp workpieces of different lengths, so that workpieces of different lengths can be clamped, thus improving the practicality of the equipment.

[0064] like Figure 5 and Figure 7 As shown, the anti-force block 44 is fixedly connected to the lower side of the support plate 21, and the side of the anti-force block 44 away from the support plate 21 is fixedly connected to the upper side of the lifting platform 133.

[0065] The resisting block 44 can increase the local thickness of the tension plate 23, so that when the telescopic shaft of the displacement cylinder 41 is pushed out, it will not interfere with the lifting platform 133, thereby ensuring the operation of the displacement component.

[0066] The principle of this embodiment is as follows:

[0067] The accelerator, consisting of a high-energy X-ray accelerator head 11 and a high-voltage and control module 14, features switchable energy levels of 9MeV and 6MeV, a compact structure, simple operation, low radiation leakage rate, safe and reliable operation, and stable performance. It provides superior penetration imaging. The high-energy X-rays emitted from the accelerator system head 11 pass through a central concrete cylinder. The accelerator system casing has two exit ports. The X-rays emitted from these ports pass through the concrete cylinder and are received by the flat-panel imaging unit 121 and the linear array imaging unit 122 on one side, respectively. The actions of the flat-panel imaging unit 121 and the linear array imaging unit 122 result in clearer and more convenient imaging. The user extracts data, and then, through the linear guide rail 131, turntable 132, and lifting platform 133, the clamped workpiece can be moved, rotated, and lifted, so that the X-rays generated by the high-energy X-ray accelerator head 11 can irradiate different areas of the concrete cylinder, thereby improving the experimental data of the concrete cylinder and reducing the impact of the radiation of the high-energy X-ray accelerator head 11 on the surrounding environment. At the same time, by using the high-energy X-ray accelerator head 11 in conjunction with the flat panel linear array imaging unit 12, real-time transmission images of the inside of the object under test can be observed, thereby measuring information such as the size and length of the object inside the object under test. Meanwhile, the image processing system completes the storage and processing of the images to improve the image clarity and ensure the accuracy of the evaluation.

[0068] Furthermore, through the mechanical system 13, the internal structure and defects of concrete cylinders with different diameters and lengths can be inspected by imaging, thus improving the practicality of the equipment.

[0069] The work of clamping and assembling prices:

[0070] The pressure cylinder 28 provides shock absorption and buffering for the workpiece hoisted on the support frame 29, thereby protecting the support frame 29. Then, the servo motor 211 can precisely control the rotation of the double-ended lead screw 25, adjust the position of the transmission block 27 on the double-ended lead screw 25, and also rotate the adjusting screw 31 to adjust the position of the adjusting block 32 on the adjusting screw 31. All of these can adjust the opening angle between the two support frames 29, so that the support frame 29 can accommodate workpieces of different diameters, thereby improving the practicality of the equipment.

[0071] How the shift component works:

[0072] By resetting the telescopic shaft of the shift cylinder 41, the linkage block 42 can be moved towards the limiting plate 210, thereby causing the tension plates 23 on both sides to slide. That is, by working the shift cylinder 41, the distance between the two tension plates 23 can be directly controlled, so that the support frame 29 connected to the tension plate 23 can clamp workpieces of different lengths, so that workpieces of different lengths can be clamped, thus improving the practicality of the equipment.

[0073] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
