[0031] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0032] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] In the description of this invention, non-limiting terms are used. Figure 1 The labels “front,” “back,” “up,” “down,” “left,” and “right” shown are used to facilitate understanding of this embodiment and are not intended to limit the invention. Specifically, front-back indicates longitudinal direction, left-right indicates lateral direction, and up-down indicates vertical direction.

[0034] Figures 1-15 An embodiment of the steel plate side inspection device of the present invention is shown, including a laterally movable support 1. A flaw detection mechanism 5 is provided on the lower side of the movable support 1. The flaw detection mechanism 5 includes an inclined flaw detection probe 51. The flaw detection probe 51 is connected to a controller (not shown in the figure). Under the control of the controller, the flaw detection probe 51 synthesizes and generates a synthetic ultrasonic beam required for flaw detection, and performs automatic flaw detection on the side of the steel plate based on the synthetic ultrasonic beam.

[0035] In this invention, a steel plate is moved longitudinally by a roller, and a steel plate side detection device is set on both sides of the steel plate. When the steel plate moves longitudinally, the steel plate side detection devices located on both sides of the steel plate detect the two sides of the steel plate respectively, thereby greatly improving the efficiency and accuracy of steel plate side detection.

[0036] Preferably, the flaw detection probe 51 controls the transmission and reception time of the flaw detection probe 51 through the controller, thereby controlling the beam angle, focusing depth, focusing size, etc. of the flaw detection probe 51, so as to realize automatic flaw detection of the steel plate at multiple positions and / or multiple angles.

[0037] The flaw detection probe 51 includes shear wave probes located on both sides, and multiple longitudinal wave probes between the shear wave probes, with the multiple longitudinal wave probes arranged alternately.

[0038] The shear wave probe is a 5M probe configuration with the following parameters: 2.5L128-1.2*12, total probe length 128*1.2=153.6mm, and effective coverage width (128-10)*1.2=141.6mm. The detection aperture is 10mm, meaning the virtual probe size is 12*12mm. At the highest precision detection, the virtual probe's peak beam gap is 1.2mm, allowing for optimal defect area and amplitude evaluation. With a controller, the signal-to-noise ratio over the sound path can be improved. The shear wave probe uses an incident angle of 10-20 degrees, preferably 19 degrees, causing waveform conversion at the steel plate interface, forming a 45-degree shear wave within the steel plate for detection.

[0039] The longitudinal wave probe is configured with a 7M probe for longitudinal wave detection. Probe parameters: 7L128-1.2*12, the total length of the longitudinal wave probe is 128*1.2=153.6mm, and the effective coverage width is (128-10)*1.2=141.6mm; the detection aperture is 10, that is, the virtual probe size is 12*12. At the highest precision detection, the virtual probe can obtain a peak gap of 1.2mm, at which point the best defect area and amplitude evaluation can be obtained; the longitudinal wave probe, together with the controller, can achieve depth focusing from 0 to 200mm, which can greatly improve the detection signal-to-noise ratio and resolution over the sound path; the longitudinal wave probe uses 0 degrees-10 degrees, with 0 degree incident angle preferred.

[0040] The movable support 1 can be set on the gantry (not shown in the figure). The gantry includes two vertically set legs and a horizontal beam set between the two legs. The gantry can be erected on the upper side of the steel plate. The horizontal beam of the gantry is directly above the steel plate. The movable support 1 can move laterally on the horizontal beam.

[0041] like Figure 2 and Figure 3As shown, the movable support 1 includes a movable rod 11 and a mounting box 12. The movable rod 11 is used to connect to the gantry cable chain (not shown in the figure) on the gantry frame, and the gantry cable chain drives the side detection device to move laterally on the crossbeam of the gantry frame. The mounting box 12 is located on the lower side of the movable rod 11, and the flaw detection mechanism 5 is installed at the lower end of the mounting box 12.

[0042] like Figure 6 As shown, the mounting box 12 includes a vertically arranged first mounting box body 121 and a second mounting box body 122 horizontally arranged at the lower end of the first mounting box body 121. The second mounting box body 122 extends away from the moving rod 11. The flaw detection mechanism 5 is installed at the lower end of the second mounting box body 122.

[0043] Preferred, such as Figure 2 As shown, the first mounting box 121 has a first accommodating space. The rear side of the first mounting box 121 is provided with a driving component 2 for driving the movable bracket 1 to move and a roller assembly 23. The roller assembly 23 is used to surround the crossbeam guide rail (not shown in the figure) and can roll along the crossbeam guide rail. The driving component 2 is used to drive the movable bracket 1 to move, so that the roller assembly 23 moves laterally along the crossbeam guide rail.

[0044] Preferred, such as Figure 2 As shown, the drive assembly 2 includes a drive motor 21 and a drive gear 22. The drive motor 21 is disposed within the first accommodating space, and the drive gear 22 is located on the rear exterior of the first accommodating space. A crossbeam guide rail and a drive rack (not shown in the figure) are arranged laterally on the front side of the crossbeam. The roller assembly 23 surrounds the outer side of the crossbeam guide rail and can move laterally along the crossbeam guide rail. The drive gear 22 meshes with the drive rack. The drive motor 21 drives the drive gear 22 to rotate, and the drive gear 22 rotates and moves laterally along the drive rack, causing the movable bracket 1 to move laterally along the crossbeam guide rail.

[0045] Preferred, such as Figure 7As shown, the roller assembly 23 includes a first fixing component 231, a second fixing component 232, a vertical roller 233, a first transverse roller 234, and a second transverse roller 235. The first fixing component 231 is disposed on the rear side of the first mounting housing 121 and is used to fix the second fixing component 232. The second fixing component 232 includes a first fixing part 2321 fixedly connected to the first fixing component 231, and a first connecting part 2322 extending from the upper end of the first fixing part 2321 away from the first mounting housing 121. The second fixing part 2323 extends downward from the middle of the right side, the second connecting part 2324 extends downward from the lower left end of the first connecting part 2322, and the third fixing part 2325 extends laterally from both sides of the second connecting part 2324; the second fixing part 2323 is used to set the vertical roller 233, and the two ends of the third fixing part 2325 are respectively provided with a first transverse roller 234 and a second transverse roller 235. The first transverse roller 234 and the second transverse roller 235 are engaged on both sides of the transverse beam guide rail, and the vertical roller 233 abuts against the upper end surface of the transverse beam guide rail.

[0046] The vertical roller 233, the first transverse roller 234, and the second transverse roller 235 of the roller assembly 23 are mounted on the periphery of the crossbeam guide rail, enabling the movable support 1 to move laterally along the crossbeam guide rail. This design has the advantages of compact structure and small space occupation.

[0047] Preferably, there are two pairs of roller assemblies 23, which are symmetrically arranged on the upper and lower sides of the rear side of the movable support 1, and one drive assembly 2 is provided, which is located in the middle of the right side of the movable support 1.

[0048] Preferred, such as Figure 7 As shown, a safety protection seat 236 is also provided on the upper rear side of the first mounting box 121. The safety protection seat 236 includes a latch that is adapted to the crossbeam guide rail. The latch is used to lock the crossbeam guide rail to prevent the roller assembly 23 from sliding off the crossbeam guide rail and improve safety.

[0049] The drive assembly 2 and the roller assembly 23 enable the movable support 1 to move laterally, facilitating a significant adjustment of the lateral position of the flaw detection mechanism 5 on the movable support 1.

[0050] A protective frame 3 is provided on the lower side of the second mounting box 122, and the flaw detection mechanism 5 is located inside the protective frame 3.

[0051] Preferred, such as Figure 1 , Figure 6 and Figure 8As shown, the protective frame 3 can move laterally relative to the second mounting housing 122. Specifically, the second mounting housing 122 includes a mounting base plate 1221, mounting side plates 1222, and a mounting sealing cover 1223. The mounting side plates 1222 are disposed on the upper surface of the mounting base plate 1221, and the mounting sealing cover 1223 is disposed at the upper end of the mounting side plates 1222. The mounting base plate 1221, the mounting side plates 1222, and the mounting sealing cover 1223 enclose a second accommodating space. Figure 9 As shown, the second accommodating space is equipped with a first telescopic rod 35 that drives the protective frame 3 to move laterally. A pair of spaced-apart guard plate fixing blocks 36 are provided on the top surface of the protective frame 3. The guard plate fixing blocks 36 are slidably connected to guard plate slide rails 37, which are fixedly connected to the protective frame 3. The fixed end of the first telescopic rod 35 can be fixedly mounted on the mounting base plate 1221 of the second mounting box 122, and the free end extends to the right through the mounting side plate 1222, connecting to a first connecting seat 38. The first connecting seat 38 is fixed to the upper end of the protective frame 3. When the first telescopic rod 35 retracts, it drives the protective frame 3 to move laterally via the first connecting seat 38. The extension and retraction of the first telescopic rod 35 drives the guard plate slide rails 37 on the protective frame 3 to move laterally along the guard plate fixing blocks 36. This allows the wheel assembly 4 and the flaw detection mechanism 5, located within the protective frame 3, to move laterally, making slight adjustments to their lateral positions, thereby achieving precise control of the flaw detection mechanism 5's position.

[0052] Preferred, such as Figure 2 As shown, a cable chain 310 is connected to the upper part of the second mounting box 122. The cable chain 310 is connected to the protective frame 3. The cable chain 310 is used to set the cable connecting the flaw detection mechanism 5. When the flaw detection mechanism 5 moves, it is connected to the flaw detection mechanism 5 through the movable cable in the cable chain 310.

[0053] Preferred, such as Figure 2 As shown, a linear displacement sensor 39 is provided on the upper rear surface of the protective frame 3. The linear displacement sensor 39 is used to detect the displacement of the protective frame 3. The controller can accurately adjust the moving distance of the protective frame 3 based on the displacement detected by the linear displacement sensor 39, thereby improving the accuracy of the movement of the protective frame 3.

[0054] like Figure 2 and Figure 10 As shown, the slider 391 of the linear displacement sensor 39 is located at the lower middle position of the rear of the first mounting box 12. The variable resistance slide rail 392 of the linear displacement sensor 39 is fixedly mounted on the upper surface of the protective frame 3. The slider 391 can slide on the upper side of the variable resistance slide rail 392.

[0055] Preferred, such as Figure 8 As shown, the protective frame 3 includes an upper protective top plate 31, a left protective side plate 32, and multiple protective partitions 33. Each protective partition 33 includes a vertically oriented vertical portion and a horizontally extending middle portion. The protective partitions 33 are evenly distributed on the lower surface of the protective top plate 31. A third accommodating space exists between the protective partitions 33. A wheel assembly 4 is disposed within this third accommodating space. The wheel assembly 4 includes a wheel 41, which abuts against the side of the steel plate. Each wheel 41 includes a fixed shaft and a rotating wheel, which can rotate relative to the fixed shaft via a bearing.

[0056] Preferred, such as Figure 11 As shown, the wheel 41 is adjustable by swinging. A wheel hinge plate 42 is provided on the lower inner side of the protective side plate 32. The wheel hinge plate 42 is hinged to a wheel connector 43, and the fixed shaft is fixedly disposed on the outer side of the wheel connector 43. The wheel connector 43 includes two symmetrically arranged hinged sub-components. The first end of the wheel connector 43 is hinged to the wheel hinge plate 42, and the second end of the wheel connector 43 is hinged to the free end of the wheel telescopic rod 44. The fixed end of the wheel telescopic rod 44 is hinged to the lower part of the protective top plate 31. The wheel telescopic rod 44 is used to drive the wheel 41 to swing around the first end as an axis, causing the wheel 41 to contact or move away from the side of the steel plate.

[0057] Preferred, such as Figure 5 As shown, the free end and fixed end of the guide wheel telescopic rod 44 are diagonally arranged. The free end of the guide wheel telescopic rod 44 is located on the lower right front part of the protective frame 3, and the fixed end is located on the upper left front part of the protective frame 3. When the guide wheel telescopic rod 44 retracts, it can drive the guide wheel 41 to swing around the first end as the axis, so that the guide wheel 41 touches or moves away from the side of the steel plate.

[0058] A steel plate side detection device is set on both the left and right sides of the steel plate. The left and right side rollers 41 respectively abut against the left and right sides of the steel plate, thereby limiting the longitudinal movement position of the steel plate. When the steel plate is moved longitudinally by the roller, the side rollers 41 also facilitate the movement of the steel plate relative to the steel plate side detection device, so as to detect the side of the entire steel plate.

[0059] Preferred, such as Figure 3 , Figure 8 and Figure 12As shown, a flaw detection mounting plate 34 is provided on the right side of the protective side plate 32. The flaw detection mounting plate 34 is used to set the flaw detection mechanism 5. The flaw detection mechanism 5 includes a flaw detection driving component 52 and a flaw detection component 56. The flaw detection driving component 52 is used to drive the flaw detection component 56 to move vertically. The flaw detection component 56 includes a flaw detection probe 51, which is used to detect the side of the steel plate.

[0060] Preferred, such as Figure 12 As shown, the flaw detection drive assembly 52 includes a probe arm 521, and a probe arm telescopic rod 522 is provided on the side of the probe arm 521. The probe arm telescopic rod 522 is a pneumatic probe arm telescopic rod. The upper end of the probe arm telescopic rod 522 is located on the top surface of the upper end of the flaw detection mounting plate 34, and the lower end is connected to the lower end of the probe arm 521. The probe arm telescopic rod 522 can drive the flaw detection assembly 56 below it to move up and down, thereby flexibly adjusting the up and down position of the flaw detection assembly 56.

[0061] Furthermore, such as Figure 12 As shown, the flaw detection drive assembly 52 also includes a swing assembly 53, which is used to limit the moving distance of the probe arm 521 and ensure the stability of the movement of the probe arm 521.

[0062] Preferred, such as Figure 12 As shown, the swing assembly 53 includes a first swing member 531, a second swing member 532, and a swing fixing member 533. One end of the first swing member 531 and the second swing member 532 are respectively hinged to the probe arm 521, and the other end is respectively hinged to both ends of the swing fixing member 533. The swing fixing member 533 is fixedly installed on the inner wall of the side of the flaw detection mounting plate 34. When the probe arm extension rod 522 drives the probe arm 521 to move up and down, the first swing member 531 and the second swing member 532 swing accordingly, limiting the extreme positions of the probe arm 521's up and down movement and ensuring the stability of the probe arm 521's movement.

[0063] Furthermore, such as Figure 12 As shown, the flaw detection drive assembly 52 further includes a connecting assembly 54. The connecting assembly 54 includes a connecting mounting base plate 541, a crash barrier 542, a first connecting arm 543, and a second connecting arm 544. The connecting mounting base plate 541 is located at the lower end of the probe arm 521, and the crash barrier 542 is located at the lower end of the swing fixing member 533, adjacent to the steel plate, to prevent the steel plate from colliding with the flaw detection mechanism 5. One end of the first connecting arm 543 is hinged to the connecting mounting base plate 541, and the other end is hinged to the flaw detection assembly 56. One end of the second connecting arm 544 is hinged to the crash barrier 542, and the other end is hinged to the flaw detection assembly 56. This allows the flaw detection assembly 56 to have a certain range of motion, ensuring the flexible movement of the flaw detection assembly 56 and guaranteeing the detection of the flaw detection probe 51.

[0064] Preferred, such as Figure 12 As shown, the anti-collision plate 542 has a slope extending upwards from the center, thereby preventing direct collision with the flaw detection drive assembly 52 and providing safety during use.

[0065] Preferred, such as Figure 12 As shown, the flaw detection drive assembly 52 also includes a flaw detection tension spring 55. One end of the flaw detection tension spring 55 is fixed to the lower end of the probe arm 521, and the other end is located on the top surface of the upper end of the flaw detection mounting plate 34. When the probe arm telescopic rod 522 is accidentally damaged or the workshop air supply is interrupted, the flaw detection tension spring 55 will pull the probe arm 521 upward to ensure the safety of the flaw detection assembly 56.

[0066] like Figure 13 As shown, the flaw detection assembly 56 includes a flaw detection mounting base 561, which is used to mount the flaw detection probe 51.

[0067] Preferred, such as Figure 14 As shown, the flaw detection mounting base 561 has a mounting hole in the middle for holding the flaw detection probe 51. The flaw detection mounting base 561 is provided with a probe pressure plate 562, which is located directly above the mounting hole and is used to press the flaw detection probe 51.

[0068] Preferred, such as Figure 14 As shown, the flaw detection probe 51 is tilted on the flaw detection mounting base 561, and the tilt angle of the flaw detection probe 51 relative to the flaw detection mounting base 561 is 10°-30°, preferably 19°. This allows the flaw detection probe 51 to cover the side of the steel plate, improving the accuracy of the side detection of the steel plate.

[0069] Preferred, such as Figure 15 As shown, a water-filled mounting base 563 is provided at the lower part of the flaw detection mounting base 561. The water-filled mounting base 563 is hinged between the first connecting arm 543 and the second connecting arm 544. Hinges 5631 extend from both sides of the water-filled mounting base 563. The two hinges 5631 are used to hinge the first connecting arm 543 and the second connecting arm 544 respectively. This allows the flaw detection assembly 56 to have a certain range of motion, ensuring the flexible movement of the flaw detection assembly 56 and guaranteeing the coupling detection of the flaw detection probe 51.

[0070] Preferred, such as Figure 15 As shown, the water tank mounting base 563 is provided with a quick connector 5632 for connecting the water outlet pipe. The array frame is provided with a water inlet pipe, which is connected to the water outlet pipe. The water outlet pipe is connected to the quick connector, which can discharge water to the lower side of the flaw detection probe 51 to remove impurities on the steel plate and improve detection accuracy.

[0071] Preferred, such as Figure 1 and Figure 4 As shown, a water and electricity control box 6 is provided on the side of the protective frame 3. A water inlet pipe is provided inside the water and electricity control box. The water inlet pipe is connected to a water distributor 61. The water distributor 61 is connected to a manual ball valve and / or an automatic ball valve 62. The automatic ball valve is a pneumatic ball valve. The manual ball valve and / or the automatic ball valve 62 are connected to the water outlet pipe, thereby enabling automatic control of the water output as needed.

[0072] The water and electricity control box 6 is also equipped with a cable that connects to the flaw detection probe 51. The cable can supply power and transmit data to the flaw detection probe 51.

[0073] Preferred, such as Figure 1 and Figure 4 As shown, an instrument box 7 is provided on the upper front side of the first mounting housing 121. Inside the instrument box 7 is a computer 71 connected to a controller. The computer 71 controls the operation of the steel plate side inspection device. The controller transmits the data detected by the synthetic ultrasonic beam to the computer 71, which then performs computer simulation modeling and displays the inspected steel plate. The software displays defect information from the top view of the steel plate through inspection data charts. Simultaneously, the software employs artificial intelligence algorithms such as decoupling characterization and machine learning to obtain more quantitative parameters of the precise location, size, and shape of the defects, while also providing a clear and rapid three-dimensional display of the defects.
