Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a non-destructive testing device and method for special equipment. Background Technology

[0002] Non-destructive testing (NDT) is a core technology for quality control throughout the entire lifecycle of special equipment. It can quantitatively assess the material uniformity and structural integrity of components without damaging the components themselves or requiring disassembly, covering the entire process from raw material acceptance and factory verification to in-service periodic inspections. This type of testing equipment can output standardized test data, supporting equipment compliance review and operation and maintenance assessment, ensuring stable equipment operation safety, and reducing maintenance losses. It is a key supporting equipment for implementing special equipment safety supervision standards and ensuring the smooth operation of production.

[0003] The existing invention patent with publication number CN117434091A discloses a non-destructive testing method for a gas cylinder with openings at both ends, belonging to the field of metal non-destructive testing technology. The method includes: S1: clamping the gas cylinder with openings at both ends onto a non-destructive testing device; S2: the threaded rod of the non-destructive testing device passes through the openings at both ends of the gas cylinder, and the emitting device moves multiple times along the axis of the threaded rod, with each movement distance set to S, where S is less than the length of the gas cylinder; after each movement, the emitting device stops for a period of time, set to t, during which time the emitting device emits an X-ray that passes through the side wall of the gas cylinder and is exposed on a photosensitive plate; the emitting device moves from the outside of one end of the gas cylinder, through the inside of the gas cylinder, to the outside of the other end of the gas cylinder; S3: using image analysis technology, the shape and location of the crack after multiple exposures on the photosensitive plate are analyzed through image fusion processing to determine the shape of the crack and its location within the gas cylinder. This detection scheme can detect cracks in gas cylinders without rotating the emitting device.

[0004] Based on the aforementioned existing technologies, most existing X-ray nondestructive testing technologies employ fixed or limited-angle imaging structures, lacking multi-degree-of-freedom angle adjustment capabilities and making it difficult to cover blind spots in complex structure detection. At the same time, X-ray sources and detectors are usually linked and fixed, and the distance cannot be adjusted independently, resulting in poor adaptability of imaging magnification and penetration capability. Furthermore, imaging parameters mostly rely on manual experience for adjustment, lacking a systematic multi-parameter optimization mechanism, resulting in insufficient stability and adaptability of imaging quality.

Beneficial effects

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 - Figure 10 The present invention provides a technical solution: A non-destructive testing device and method for special equipment includes a support frame 1, with a testing mechanism 2 disposed above the support frame 1 for testing the special equipment. The testing mechanism 2 includes: The adjusting assembly 21 includes a support ring 211 fixedly mounted on the top of the support frame 1. A guide ring 212 is fixedly mounted inside the support ring 211. A movable ring 213 is fitted inside the guide ring 212. Ball bearing plates 214 are fixedly mounted on both sides of the movable ring 213. Gear rings 215 are fixedly mounted inside the guide ring 212 and the movable ring 213. Stepper motors 216 are fixedly mounted on the upper sides of the guide ring 212. A coupling 217 is connected to the lower end of the shaft of the stepper motor 216. Drive shafts 218 are inserted and mounted on both sides of the guide ring 212. A gear 219 is fixedly mounted at the center of the drive shaft 218. Miniature electric cylinders 2110 are fixedly mounted on the lower sides of the guide ring 212. A pressure plate 2111 is sleeved on the outer side of the miniature electric cylinder 2110, and a rubber pad 2112 is fixedly mounted on one side of the pressure plate 2111. A movable frame 2113 is fitted inside the movable ring 213. Vertical cylinders are evenly distributed in a ring shape at equal angles above the support frame 1. The support ring 211 is fixed to the top of the support frame 1. The guide ring 212 is fixedly connected to the support frame 1 through the support ring 211, and the inner side of the guide ring 212 is provided with… The ring has an annular groove, and a toothed ring 215 is fixed within the groove structure of the guide ring 212. The top and bottom centers of the guide ring 212 have guide grooves that engage with the ball bearing plate 214. The movable ring 213 is rotatably connected to the guide ring 212 via the ball bearing plate 214. A toothed ring 215 is also installed inside the inner groove of the movable ring 213. The movable frame 2113 is fitted into the inner groove structure of the movable ring 213, and a rotatable connection is formed between the movable frame 2113 and the movable ring 213. Drive shafts and gears 219 are also installed on both sides of the movable frame 2113. The gears 219 on both sides of 2113 mesh with the internal gear ring 215 of the movable ring 213. The two sides of the movable frame 2113 are also fixedly installed with a stepper motor 216, a coupling 217, a miniature electric cylinder 2110 and a pressure plate 2111. The center of the pressure plate 2111 is provided with a through hole with a diameter larger than that of the drive shaft 218. The pressure plate 2111 is movably connected to the movable ring 213 and the movable frame 2113 through the miniature electric cylinder 2110. One end of the drive shaft 218 is provided with a disc-shaped protrusion, and a rubber pad 2112 is sleeved on both sides of the disc-shaped protrusion of the drive shaft 218.

[0029] Specifically, the adjustment component 21 is used to adjust the angle of the detection component 22 in multiple spatial directions. The guide ring 212 is fixedly mounted on the support component 23, the movable ring 213 is movably disposed inside the guide ring 212, and the movable frame 2113 is movably disposed inside the movable ring 213, the movable frame 2113 having a semi-circular ring structure. The guide ring 212 and the movable ring 213, as well as the movable ring 213 and the movable frame 2113, are all connected by rolling links via ball bearing plates 214. Grooves on the upper and lower sides of the guide ring 212 limit the movement of the ball bearing plates 214, restricting the axial movement of the movable ring 213 so that the movable ring 213 can only rotate circumferentially along the guide ring 212.

[0030] During the testing process, after the stepper motor 216 starts, it drives the drive shaft 218 to rotate via the coupling 217. The drive shaft 218 drives the gear 219 to rotate, and the gear 219 meshes with the corresponding gear ring 215, thereby driving the movable ring 213 to rotate along the guide ring 212 or driving the movable frame 2113 to rotate along the movable ring 213, realizing the angle adjustment of the detection component 22 in different directions. When the detection component 22 is adjusted to the target detection angle, the micro electric cylinder 2110 drives the pressure plate 2111 to move towards the drive shaft 218, so that the pressure plate 2111 presses against the rubber pads 2112 set on both sides of the disc structure of the drive shaft 218. By increasing the friction, the drive shaft 218 is locked, preventing the movable ring 213 or the movable frame 2113 from deflecting due to vibration during the testing process, thereby ensuring the stability of the detection angle and the accuracy of the detection results. The detection component 22 is located inside the adjustment component 21 and is used to generate X-rays for flaw detection. The detection component 22 includes adjustment push rods 221 fixedly installed on both sides of the movable frame 2113. A limit frame 222 is provided on one side of the movable frame 2113, and a light source 223 is fixedly installed on the inner side of the limit frame 222. A transfer frame 224 is provided on the other side of the movable frame 2113, and a digital detector 225 is fixedly installed on one side of the transfer frame 224. The limit frame 222 is installed on one side of the movable frame 2113 via the adjustment push rod 221, and the transfer frame 224 is installed on the other side of the movable frame 2113 via the adjustment push rod 221. The installation positions of the light source 223 and the digital detector 225 are located on both sides of the center of the movable ring 213.

[0031] Specifically, the detection component 22 is used to complete the emission and reception of X-rays. During detection, the light source 223 emits X-rays and irradiates the special equipment to be inspected. The rays that penetrate the area to be inspected are received by the digital detector 225 and converted into digital image signals.

[0032] To accommodate devices of varying thicknesses and structural forms, the light source 223 and digital detector 225 are mounted on independent adjustment mechanisms. Driven by the adjustment push rod 221, they can move towards or away from the device under inspection, thereby independently adjusting the distances between the light source 223 and the device, as well as between the digital detector 225 and the device. At the same inspection angle, the control component 24 can control the light source 223 and digital detector 225 to perform multiple inspections at preset distances, acquiring multiple sets of inspection images with different magnifications and imaging effects. By comparing the clarity and defect display effect of each set of inspection images, the inspection result with the best imaging quality is selected, thereby improving the inspection adaptability and defect identification capability under different working conditions. Support component 23 is disposed at the bottom of support frame 1 and is used to support special equipment. Support component 23 includes a sleeve 231 fixedly installed at the bottom of support frame 1, a bracket 232 inserted above the sleeve 231, and a turntable 233 fixedly installed above the bracket 232. Support rods 234 are fixedly installed on both sides of support frame 1, and support push rods 235 are fixedly installed above the support rods 234. The four corners of the bracket 232 are provided with columnar protrusions that are slidably connected to the sleeve 231. The turntable 233 is located at the center of support frame 1. The bottom end of the support push rod 235 is fixedly connected to the support rod 234, and the movable end is fixedly connected to the bottom surface of the bracket 232.

[0033] Specifically, the support component 23 is used to support and position the special equipment to be inspected. Before inspection, the height of the equipment to be inspected is adjusted by the support component 23 so that the area to be inspected is within the optimal inspection range of the inspection component 22.

[0034] Because the bottom of the movable ring 213 is located between the rod-like structures below the bracket 232, the rod-like structures of the bracket 232 restrict the rotation range of the movable ring 213, preventing it from completing a full rotation along the guide ring 212. When the movable ring 213 rotates to its limit position, some detection areas may no longer be able to be covered by the adjustment component 21. Therefore, a turntable 233 is provided on the support component 23. The device to be tested is mounted on the turntable 233, which can drive the device to be tested to rotate around its own axis. During the testing process, the turntable 233 changes the orientation of the device to be tested, allowing previously inaccessible detection areas to rotate into the coverage area of ​​the detection component 22. This, in conjunction with the adjustment component 21, enables omnidirectional detection of the device, improving detection coverage and reducing blind spots. The control component 24 is located above the support frame 1 and is used to control the adjustment component 21. The control component 24 includes a mounting bracket 241 fixedly installed on the top of the support frame 1, and a control module 242 is fixedly installed on one side of the mounting bracket 241.

[0035] Specifically, the control component 24 is used to uniformly control the entire detection process. The control component 24 is electrically connected to the adjustment component 21, the detection component 22 and the support component 23 respectively, and can control the operation of the stepper motor 216, the micro electric cylinder 2110 and the turntable 233, and coordinate and manage the operating status of each actuator.

[0036] The control component 24 includes a data acquisition and storage unit for receiving detection image data output by the digital detector 225 and classifying and storing detection results acquired under different combinations of detection angles and distances. The control component 24 is also connected to a touchscreen display, which displays the equipment's operating status, current detection parameters, and real-time detection images. Operators can manually set and adjust the rotation angles of the movable ring 213, the movable frame 2113, the turntable 233, and the position parameters of the light source 223 and the digital detector 225 via the touchscreen display.

[0037] During actual testing, the control component 24 can automatically control the movable ring 213, movable frame 2113, light source 223, digital detector 225 and turntable 233 to switch to different testing conditions in sequence according to the preset program, so as to realize automatic testing at multiple angles and distances; at the same time, it can also be manually intervened and adjusted according to the control commands input by the operator to meet the usage needs of different testing scenarios and improve the automation level and operational flexibility of the testing process.

[0038] This invention also discloses a method for a non-destructive testing device for special equipment, comprising the following steps: S1. Place the device to be tested on the support component 23, and adjust the position of the device to be tested through the support component 23 so that the area to be tested is within the detection range of the detection component 22; S2. The control component 24 controls the operation of the adjustment component 21, adjusts the detection direction of the detection component 22, and works with the support component 23 to adjust the orientation of the device to be detected, so that the area to be detected is in the optimal detection position. S3, Control component 24 controls detection component 22 to adjust detection conditions, changes the relative position between detection component 22 and the device under test, and forms different combinations of detection parameters; S4. The detection component 22 performs X-ray detection on the equipment to be detected, acquires detection image data, and the control component 24 collects and stores the data. S5, the control component 24 controls the adjustment component 21 and the detection component 22 to repeatedly perform detection under different angles and different detection parameters, and filters the acquired detection images to output the detection result with the best imaging effect.

[0039] Specifically, the control component 24 includes a mounting bracket 241 and a control module 242. The control module 242 is used to achieve unified control and coordinated drive of the adjustment component 21, the detection component 22, and the support component 23. The control module 242 preferably adopts an industrial-grade embedded control system to perform detection process control, motion trajectory planning, and multi-condition parameter switching. It also interacts with each execution component through an industrial communication interface to achieve automated control of the detection process. The stepper motor 216 preferably adopts a Leadshine 86HS series or MOONS 86BYG series hybrid stepper motor to drive the gear transmission structure in the adjustment component 21, realizing the angle graded adjustment and multi-position repetitive positioning control of the detection component 22. The miniature electric cylinder 2110 preferably adopts an SMC LEY series electric actuator or an IAI RCP6 series electric cylinder to drive the pressure plate 2111 to lock the drive shaft 218, and realizes precise adjustment of the detection distance and multi-condition switching under the control of the control module 242. The digital detector 225 preferably adopts a Varex Imaging PaxScan. The 2530DXI digital flat panel detector or the PerkinElmer XRD series digital detector is used to receive the X-ray signal after penetrating the device under test and convert it into digital image data for output to the control module 242 to achieve high-resolution image acquisition and storage. The support push rod 235 preferably adopts the TiMOTIONJP series electric push rod or the Firgelli L16 industrial linear push rod to drive the bracket 232 and the turntable 233 in the support assembly 23 to adjust the height and posture, so that the device under test is always within the effective detection range of the detection assembly 22, and cooperates with the adjustment assembly 21 to realize posture compensation during multi-angle detection. Through the coordinated control of the stepper motor 216, the miniature electric cylinder 2110, the digital detector 225 and the support push rod 235 by the control module 242, the automatic execution of detection angle adjustment, detection distance adjustment and multi-posture scanning is realized, thereby completing the X-ray detection process under multi-angle and multi-parameter conditions. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0040] During operation, before the test begins, the special equipment to be tested is placed on the turntable 233 of the support component 23. The support push rod 235 drives the bracket 232 to rise and fall, so that the test area of ​​the equipment to be tested enters the effective test range of the test component 22, thereby completing the initial positioning.

[0041] Subsequently, control component 24 activates control module 242, driving adjustment component 21 to operate. Stepper motor 216 drives gear 219 to mesh with gear ring 215, causing movable ring 213 to rotate circumferentially relative to guide ring 212. Simultaneously, it drives movable frame 2113 to rotate synchronously or independently within movable ring 213, thereby driving detection component 22 to achieve multi-directional angle adjustment, aligning light source 223 and digital detector 225 with the area to be detected.

[0042] Once the detection angle is adjusted to the target position, the control component 24 controls the micro electric cylinder 2110 to push the pressure plate 2111 to press the rubber pads 2112 on both sides of the drive shaft 218, thereby increasing the friction to lock the movable ring 213 and the movable frame 2113, thus maintaining the stability of the current detection angle.

[0043] After the angle is locked, the control component 24 further controls the adjustment push rod 221 in the detection component 22 to move the light source 223 and the digital detector 225 in the direction of approaching or moving away from the device to be detected, thereby adjusting the X-ray emission distance and receiving distance to form different combinations of detection working condition parameters.

[0044] Subsequently, the light source 223 emits X-rays that penetrate the device under test. The digital detector 225 receives the transmitted rays and converts them into digital image data, which is then transmitted to the control component 24 for storage in real time.

[0045] At the same detection angle, the control component 24 controls the adjustment push rod 221 to repeatedly switch between different distance combinations, so that the detection component 22 performs multiple X-ray scans and acquires multiple sets of detection image data with different imaging magnification and imaging quality.

[0046] After completing multiple distance scans at the current angle, the control component 24 releases the locking state of the micro electric cylinder 2110 and re-drives the adjustment component 21 and the support component 23 to change the detection angle, thereby entering the next detection angle position and repeating the above detection process.

[0047] Finally, the control component 24 comprehensively compares and filters multiple sets of image data obtained under different angles and distance combinations, selects the image with the highest imaging clarity and the most obvious defect display as the final detection result, and outputs it through the display terminal for the operator to judge.
