Description

Technical Field

[0001] The present application relates to the technical field of concrete component detection, and in particular to a device and method for detecting steel bars in concrete components based on an X-ray method. Background Art

[0002] X-ray detection is a method of using X-rays to detect steel bars. This method applies X-rays to the concrete surface and observes the penetration of X-rays around the steel bars to determine the location, quantity, diameter, cracks, degree of rust, etc. of the steel bars. X-ray detection can detect steel bar problems buried deep inside the concrete, and the speed of steel bar flaw detection is relatively fast.

[0003] Traditionally, when inspecting concrete components, the X-ray detection probe is first pointed toward the concrete component, and then the X-ray detection probe is moved to inspect the concrete component. However, when the steel bars in the concrete component are superimposed in the direction of the X-rays, the superimposed steel bars will reduce the penetration of the X-rays, making it difficult for the X-rays to penetrate the entire concrete component, resulting in reduced detection accuracy. Summary of the invention

[0004] In order to improve the problem that the overlapping of superimposed steel bars will reduce the penetration of X-rays, making it difficult for X-rays to penetrate the entire concrete component, resulting in reduced detection accuracy, the present application provides a device and method for detecting steel bars in concrete components based on the X-ray method.

[0005] On the one hand, the present application provides a device for detecting steel bars in concrete components based on an X-ray method, which adopts the following technical solution:

[0006] A device for detecting steel bars in a concrete member based on an X-ray method comprises an X-ray detection probe arranged on a detection table, the detection table is provided with a support unit, the support unit is used to support the concrete member and adjust the position of the detection surface of the concrete member, the detection table is provided with a slide rail, the slide rail is arranged along the length direction of the concrete member, the slide rail is provided with an adjustment unit, the adjustment unit slides along the slide rail, the X-ray detection probe is arranged on the adjustment unit, and the adjustment unit is used to adjust the inclination angle of the X-ray detection probe.

[0007] By adopting the above technical solution, when inspecting the steel bars of a concrete component, the concrete component is first placed on the support unit and fixed, and then the X-ray detection probe is adjusted to be perpendicular to the detection surface of the concrete component through the adjustment unit, and then the X-ray detection probe is driven to inspect the concrete component, and the X-ray detection probe is adjusted to rotate to a specified tilt angle through the adjustment unit, and then the X-ray detection probe is driven to inspect the concrete component. Through the vertical and tilt detection of the X-ray detection probe, the influence of the overlapping of steel bars on the X-ray penetration and the detection of steel bars in the concrete component is reduced, thereby improving the detection accuracy of the steel bars in the concrete component.

[0008] In a specific feasible implementation scheme, the support unit includes an annular guide rail and a clamping member. The annular guide rail is arranged on the detection platform. A first notch is provided on the annular guide rail. An annular guide bar is slidably provided on the annular guide rail. Two second notches arranged opposite to each other are provided on the annular guide bar. The second notches can be connected with the first notch one by one. The two second notches divide the annular guide bar into two sliding bars. The clamping member is arranged on the sliding bar and corresponds to the sliding bar one by one. The clamping member is used to clamp the clamping surface of the concrete component. The X-ray detection probe can pass through the first notch and the second notch which are connected. At least two groups of driving members are provided on the annular guide rail. The driving member is used to drive the sliding bar to slide and pass through the first notch.

[0009] By adopting the above technical solution, when the concrete component is placed, the concrete component is first clamped by connecting the clamping member to complete the fixation of the concrete component. When the detection surface of the concrete component is adjusted to be flipped, the driving member drives the slide bar to slide in the annular guide rail, so that the concrete component is flipped, thereby improving the convenience of adjusting the detection surface of the concrete component. The X-ray detection probe can pass through the first notch and the second notch, thereby effectively avoiding the influence of the annular guide rail and the annular guide bar on the sliding of the X-ray detection probe.

[0010] In a specific possible implementation manner, the spacing between two adjacent groups of the driving members along the axial direction of the annular guide rail is greater than the width of the second notch in this direction, and is smaller than the length of the slide bar along this direction.

[0011] By adopting the above technical solution, the distance between the two driving members is limited, which can effectively avoid the two driving members moving to the second notch at the same time, thereby improving the stability of the driving members driving the slide bar.

[0012] In a specific possible implementation mode, the driving member includes a driving motor and a driving roller. The driving motor is arranged on the annular guide rail, and the driving roller is coaxially fixed on the driving motor. The driving roller can be pressed against the slide bar and drive the slide bar to slide.

[0013] By adopting the above technical solution, when the slide bar is driven, the driving motor drives the driving roller to rotate, and the driving roller drives the slide bar to slide on the annular guide rail, thereby realizing the driving of the concrete component to flip.

[0014] In a specific possible implementation scheme, the clamping member includes a clamping plate and a clamping screw. A connecting plate is provided on the slide bar. The clamping screw passes through the connecting plate and is threadedly connected to the connecting plate. The clamping plate is rotatably arranged at the end of the clamping screw. The clamping screw can drive the clamping plate to slide radially along the annular guide rail. A guide rod is provided on the clamping plate. The guide rod passes through the connecting plate and is slidably arranged with the connecting plate slide bar. The clamping plate can be clamped on the clamping surface of the concrete member.

[0015] By adopting the above technical solution, when fixing the concrete component, the operator screws the clamping screw, and the clamping screw pushes the clamping plate to slide toward the concrete component under the guidance of the guide rod. The two clamping plates clamp the two clamping surfaces of the concrete component respectively, thereby completing the clamping and fixing of the concrete component.

[0016] In a specific possible implementation scheme, the detection platform is provided with a telescopic mechanism, the telescopic mechanism is provided with a support plate, and the support plate is arranged below the concrete component and supports the detection surface of the concrete component.

[0017] By adopting the above technical solution, when the clamping plate clamps and fixes the concrete component, the telescopic mechanism pushes the support plate to support the concrete component, thereby improving the stability of the installation and fixation of the concrete component.

[0018] In a specific possible implementation scheme, the adjustment unit includes a slide plate and a locking piece. The slide plate is slidably arranged on the slide rail. The slide plate is provided with a strip-shaped through hole. The X-ray detection probe is rotatably arranged on the slide plate through a rotating shaft. The X-ray detection probe is inserted into the strip-shaped through hole and faces the concrete member. The X-ray detection probe can rotate along a vertical plane. The locking piece is arranged on the slide plate and is used to fix the X-ray detection probe at a set inclination angle.

[0019] By adopting the above technical solution, when adjusting the angle of the X-ray detection probe, the operator first drives the X-ray detection probe to rotate around the rotation axis to a specified angle, and then locks the X-ray detection probe to this position through a locking member, thereby improving the stability of the X-ray detection probe when the slide plate slides.

[0020] In a specific possible implementation scheme, the slide plate is provided with two arc surfaces spaced apart from each other, and the centers of the arc surfaces are colinear with the axis of the rotating shaft;

[0021] The locking member includes a slider, each of the arc surfaces is provided with a serpentine groove, the serpentine groove is arranged along the circumference of the arc surface, the crest of one serpentine groove corresponds to the trough of another serpentine groove, the slider is slidably arranged on the X-ray detection probe and corresponds one-to-one with the serpentine groove, the slider is inserted into the serpentine groove and slidably arranged, and a fixing member is provided on the slider, and the fixing member is used to limit the relative sliding of the two sliders.

[0022] By adopting the above technical solution, when the X-ray detection probe rotates around the rotation axis, the X-ray detection probe drives the slider to slide in the serpentine groove, and the two sliders move away from or close to each other when sliding in the serpentine groove, and then the sliding of the two sliders is fixed by the fixing member, so that the position of the X-ray detection probe is fixed, so that the laser ranging probe can be fixed at any tilt angle position, and at the same time, the slider is restricted by the serpentine groove wall, so that the stability of the tilt angle fixation of the laser ranging probe is improved.

[0023] In a specific implementation scheme, the fixing member includes a fixing rod and a sleeve structure. The fixing rod is arranged on the slider and corresponds to the slider one by one. The two fixing rods can be inserted from both ends of the sleeve structure and threadedly connected to the sleeve structure.

[0024] By adopting the above technical solution, when fixing the two sliders, the sleeve structure is screwed onto the two fixing rods, thereby achieving the fixation of the two sliders.

[0025] On the other hand, the present application also provides a method for detecting steel bars in concrete components based on an X-ray method, which adopts the following technical solution.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-5 This application is described in further detail.

[0041] On the one hand, an embodiment of the present application discloses a device for detecting steel bars in a concrete component based on an X-ray method.

[0042] Reference Figure 1 A device for detecting steel bars in concrete components based on an X-ray method comprises a detection platform 1, on which a slide rail 2, an X-ray detection probe 3, a support unit 4, and an adjustment unit 5 are arranged. A concrete component 6 is fixedly mounted on the support unit 4, and the support unit 4 is used to support the concrete component 6 and can adjust the positions of two detection surfaces 61 of the concrete component 6. The concrete component 6 is a long strip with a rectangular cross section. Two sets of opposite side walls of the concrete component 6, one set is a detection surface 61, and the other set is a clamping surface 62. The concrete component 6 is pre-embedded with horizontal and vertically arranged steel bars, and the horizontal bars are arranged along the length direction of the concrete component 6. The number of the slide rails 2 is two The two slide rails 2 are arranged in parallel and at intervals along the length direction of the concrete component 6. The adjustment unit 5 is slidably arranged on the slide rails 2. The operator can manually push the adjustment unit 5 to slide, or add a linear drive mechanism to drive the adjustment unit 5 to slide on the slide rails 2. The slide rails 2 are arranged along the length direction of the concrete component 6. The adjustment unit 5 slides along the slide rails 2. The X-ray detection probe 3 is arranged on the adjustment unit 5. The adjustment unit 5 is used to adjust the inclination angle of the X-ray detection probe 3. The X-ray detection probe 3 is externally connected to a display (not shown in the drawings). The operator can record the detection data of the X-ray detection probe 3 on the concrete component 6 through the display.

[0043] When inspecting the steel bars of the concrete component 6, the concrete component 6 is first placed on the support unit 4 and fixed, and then the X-ray detection probe 3 is adjusted to be perpendicular to the detection surface 61 of the concrete component 6 by the adjustment unit 5, and then the X-ray detection probe 3 is driven to inspect the concrete component 6, and then the X-ray detection probe 3 is adjusted to rotate to a specified tilt angle by the adjustment unit 5, and then the X-ray detection probe 3 is driven to inspect the concrete component 6. After inspecting one detection surface 61 of the concrete component 6, the concrete component 6 is driven to rotate by the support unit 4 so that the other detection surface 61 faces the X-ray detection probe 3, and then the above inspection process is repeated. Through the vertical and tilted inspection of the X-ray detection probe 3, the influence of the overlap of the steel bars on the X-ray penetration and the steel bar inspection in the concrete component 6 is reduced, and the inspection accuracy of the steel bars in the concrete component 6 is improved. By comparing the inspection data of the two inspection surfaces 61, the accuracy of the steel bar inspection data in the concrete component 6 is improved.

[0044] Reference Figure 1 , Figure 2 In this embodiment, there are two groups of support units 4, which are respectively arranged at both ends of the concrete component 6. Each group of support units 4 in this embodiment includes an annular guide rail 41 and a clamping member 42. There are two annular guide rails 41, which are arranged in parallel at intervals. A first notch 411 is provided on each annular guide rail 41, and the first notch 411 is located at the top of the annular guide rail 41. A slide groove 412 is provided on the opposite sides of the two annular guide rails 41. An annular guide bar 43 is provided on each annular guide rail 41, and the annular guide bar 43 is inserted into the slide groove 412 and slidably connected. Two second notches 431 arranged oppositely are provided on the annular guide bar 43, and the second notches 431 can be aligned with and connected to the first notch 411 one by one. The X-ray detection probe 3 can pass through the first notch 411 and the second notch 431 that are connected. At least two groups of driving members 44 are provided on the annular guide rail 41, and the driving member 44 is used to drive the slide bar 432 to slide and pass through the first notch 411.

[0045] Reference Figure 2The two second notches 431 divide the annular guide bar 43 into two slide bars 432 . The two slide bars 432 arranged opposite to each other on different annular guide rails 41 are fixedly connected by a connecting plate 423 . The clamping member 42 is arranged on the slide bar 432 and corresponds to the connecting plate 423 one by one. The clamping member 42 in this embodiment includes a clamping plate 421 and a clamping screw 422. The clamping screw 422 passes through the connecting plate 423 and is threadedly connected to the connecting plate 423. The clamping screw 422 is arranged along the radial direction of the annular guide bar 43. The clamping plate 421 is rotatably arranged at the end of the clamping screw 422 adjacent to the concrete member 6. The clamping screw 422 can drive the clamping plate 421 to slide radially along the annular guide rail 41. A guide rod 424 is fixedly provided on the clamping plate 421. The axis of the guide rod 424 is parallel to the axis of the clamping screw 422. The guide rod 424 passes through the connecting plate 423 and is slidably arranged with the connecting plate 423. The clamping plate 421 can be clamped on the clamping surface 62 of the concrete member 6.

[0046] Reference Figure 2 , the number of driving members 44 in this embodiment is four groups, and the distance between two adjacent groups of driving members 44 along the axial direction of the annular guide rail 41 is greater than the width of the second notch 431 in this direction, and less than the length of the slide bar 432 in this direction. The driving member 44 in this embodiment includes a driving motor 441 and a driving roller 442. The number of the driving motor 441 and the driving roller 442 are both two, and they correspond one to one. The driving motor 441 is fixedly arranged on the annular guide rail 41, and the driving roller 442 is coaxially fixedly arranged on the driving motor 441. The two driving rollers 442 are respectively located on both sides of the slide bar 432. The driving roller 442 is inserted into the annular guide rail 41 and pressed against the slide bar 432. Anti-skid grooves can be provided at the contact surface between the slide bar 432 and the driving roller 442 to increase the friction between the two.

[0047] Reference Figure 1 A telescopic mechanism 45 is provided on the detection platform 1. The telescopic mechanism 45 in this embodiment is two hydraulic cylinders 451. In other embodiments, it can also be a linear motor, a cylinder, etc. The two hydraulic cylinders 451 are arranged at intervals along the length direction of the concrete component 6. The cylinder body of the hydraulic cylinder 451 is fixedly connected to the detection platform 1. The piston rod ends of the two hydraulic cylinders 451 are commonly fixed with a support plate 452. The support plate 452 is arranged below the concrete component 6 and supports the detection surface 61 of the concrete component 6.

[0048] When installing and fixing the concrete component 6, the first notch 411 is aligned with the second notch 431, and then the hydraulic cylinder 451 is driven to extend to the set position, and then the concrete component 6 is placed on the support plate 452, and then the clamping screw 422 is rotated, and the clamping screw 422 drives the clamping plate 421 to press against the clamping surface 62 of the concrete component 6, so as to clamp and fix the concrete component 6.

[0049] When the detection of one detection surface 61 of the concrete component 6 is completed, the other detection surface 61 of the concrete component 6 needs to be turned upward. At this time, the hydraulic cylinder 451 contracts and the support plate 452 moves downward. At this time, the drive motor 441 is started to rotate, and the drive motor 441 drives the drive roller 442 to rotate. The drive roller 442 drives the slide bar 432 to slide along the annular guide rail 41. At this time, the two slide bars 432 exchange positions, and the other second notch 431 is aligned with the first notch 411, so that the other detection surface 61 of the concrete component 6 faces upward, thereby improving the convenience of switching between the detection surfaces 61 of the concrete component 6.

[0050] When the first notch 411 is aligned with the second notch 431 , the X-ray detection probe 3 can slide through the first notch 411 and the second notch 431 , reducing the obstruction of the annular slide rail 2 and the annular guide bar 43 to the X-ray detection probe 3 and reducing the impact on the steel bar detection of the concrete component 6 .

[0051] Reference Figure 3 The adjustment unit 5 in this embodiment includes a slide plate 51 and a locking member 52. The slide plate 51 is slidably arranged on the slide rail 2. A strip through hole 511 is arranged on the slide plate 51. The strip through hole 511 is arranged along the sliding direction of the slide plate 51. Two support blocks 53 are fixed on the side of the slide plate 51 away from the concrete component 6. The strip through hole 511 is arranged between the two support blocks 53. The X-ray detection probe 3 is rotatably arranged on the support block 53 through a rotating shaft 54. The X-ray detection probe 3 is inserted into the strip through hole 511 and faces the concrete component 6. The axis of the rotating shaft 54 ​​is parallel to the sliding plane of the slide plate 51 and perpendicular to the sliding direction of the slide plate 51. The locking member 52 is arranged on the slide plate 51 and is used to fix the X-ray detection probe 3 at a set tilt angle.

[0052] Reference Figure 3 , Figure 4 , each support block 53 is provided with an arc surface 531, and the center of the arc surface 531 is colinear with the axis of the rotating shaft 54. The arc surface 531 is provided with a scale value 532, and the scale value 532 is arranged along the circumference of the arc surface 531, which is used to reflect the inclination angle of the X-ray detection probe 3. The locking member 52 includes a slider 521, and each arc surface 531 is provided with a serpentine groove 522, and the extended trajectory of the serpentine groove 522 is a sine trajectory. The serpentine groove 522 is arranged along the circumference of the arc surface 531, and the crest of one serpentine groove 522 corresponds to the trough of another serpentine groove 522. The slider 521 is inserted into the serpentine groove 522 and slidably arranged, and a fixing member 55 is arranged on the slider 521.

[0053] Reference Figure 3 , Figure 4The fixing member 55 in this embodiment includes a fixing rod 551 and a sleeve structure 552. The fixing rod 551 is arranged on the end surface of the X-ray detection probe 3 through a sliding support 553. The fixing rod 551 corresponds to the slider 521 one by one, and the slider 521 is fixed on the fixing rod 551.

[0054] Reference Figure 4 , Figure 5 The sliding support 553 is provided with a guide block 554, and the fixed rod 551 is provided with a guide groove 555. The guide groove 555 is arranged along the axial direction of the fixed rod 551, and the guide block 554 is inserted into the guide groove 555 and slidably connected. The sleeve structure 552 in this embodiment includes a first sleeve 5521 and two second sleeves 5522. The second sleeves 5522 correspond to the fixed rod 551 one by one. The second sleeves 5522 are threadedly sleeved on the fixed rod 551. Initially, the first sleeve 5521 is threadedly sleeved on one of the second sleeves 5522. When the two sliders 521 are fixed, the first sleeve 5521 can be screwed onto the other second sleeve 5522. The length of the first sleeve 5521 is less than the length of the second sleeve 5522. The distance between the two fixed rods 551 is greater than the distance between the two extreme positions of the fixed rod 551 driven by the slider 521. The fixed rod 551 is provided with an indicating arrow 556 for indicating the scale value 532.

[0055] When adjusting the inclination angle of the X-ray detection probe 3, the operator first drives the X-ray detection probe 3 to rotate. When the X-ray detection probe 3 rotates, the slider 521 is driven to slide in the serpentine groove 522. The slider 521 slides on the moving fixed rod 551, and the two fixed rods 551 approach or move away from each other. When the inclination angle of the X-ray detection probe 3 is adjusted to the set angle, the operator screws the first sleeve 5521 and the second sleeve 5522 so that the first sleeve 5521 is screwed onto the other second sleeve 5522, thereby fixing the two fixed rods 551. At this time, the inclination of the X-ray detection probe 3 is fixed, which improves the stability of the X-ray detection probe 3 when the slide plate 51 slides.

[0056] When the two fixing rods 551 are fixed together, the sliding of the slider 521 is restricted by the groove wall of the serpentine groove 522. Therefore, compared with the traditional fixing method relying on friction force, this solution can improve the stability and reliability of the fixing of the tilt angle of the X-ray detection probe 3.

[0057] The implementation principle of the device for detecting steel bars in concrete components based on the X-ray method in the embodiment of the present application is as follows: when detecting the steel bars of the concrete component 6, the concrete component 6 is first placed on the support unit 4 and fixed, and then the X-ray detection probe 3 is adjusted to be perpendicular to the detection surface 61 of the concrete component 6 by the adjustment unit 5, and then the X-ray detection probe 3 is driven to detect the concrete component 6, and then the X-ray detection probe 3 is adjusted to rotate to a specified tilt angle by the adjustment unit 5, and then the X-ray detection probe 3 is driven to detect the concrete component 6. After detecting one detection surface 61 of the concrete component 6, the concrete component 6 is driven to rotate by the support unit 4 so that the other detection surface 61 faces the X-ray detection probe 3, and then the above detection process is repeated. Through the vertical and tilt detection of the X-ray detection probe 3, the influence of the overlap of steel bars on the X-ray penetration and the detection of steel bars in the concrete component 6 is reduced, and the detection accuracy of the steel bars in the concrete component 6 is improved. By comparing the detection data of the two detection surfaces 61, the accuracy of the detection data of the steel bars in the concrete component 6 is improved.

[0058] On the other hand, an embodiment of the present application also discloses a method for detecting steel bars in concrete components based on X-ray method.

[0061] S2, adjusting the X-ray detection probe 3 to be perpendicular to the detection surface 61 of the concrete component 6 through the adjustment unit 5, and then driving the X-ray detection probe 3 to detect the concrete component 6;

[0062] S3, adjusting the X-ray detection probe 3 to rotate to a specified tilt angle through the adjustment unit 5, and then driving the X-ray detection probe 3 to detect the concrete component 6;

[0063] S4. Adjust the position of the concrete component 6 by the supporting unit 4 so that the detection surface 61 of another concrete component 6 faces the X-ray detection probe 3, and then repeat steps S2-S3.

[0064] In step S1 , when fixing the concrete component 6 , the two clamping screws 422 drive the clamping plates 421 to clamp and fix the clamping surface 62 of the concrete component 6 .

[0065] In step S2 , the distance that the X-ray detection probe 3 is moved by the slide 51 can be obtained through the distance sensor disposed on the slide 51 .

[0066] In step S3, the X-ray detection probe 3 can be set to have multiple tilt angles to reduce the possibility of overlapping steel bars during detection.

[0067] In step S4, detection is performed through the detection surfaces 61 of the two concrete components 6, and the two test data are compared to improve the accuracy of the detection data.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
