Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detection technology, specifically to an ultrasonic automatic flaw detection and positioning spraying device. Background Technology

[0002] Currently, ultrasonic automatic flaw detection positioning spraying technology plays a crucial role in the field of industrial non-destructive testing. With the advancement of technology, both domestic and foreign countries have accumulated rich experience in this field and developed a variety of relatively mature ultrasonic automatic flaw detection positioning spraying devices. These devices mainly rely on alarm signals to achieve precise positioning in the length direction during probe rotation and straight pipe penetration testing.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN215768399U, which discloses an ultrasonic flaw detection device. This patent utilizes magnetic adsorption and a Mecanum wheel drive mechanism to automatically move on the workpiece surface for flaw detection, eliminating the need for manual handling, reducing labor costs, and enabling comprehensive, blind-spot-free detection to avoid missed detections. However, this patent has significant limitations. The moving platform can only perform single linear movement and cannot be accurately adjusted according to the object being inspected. Furthermore, it can only process planar objects and cannot inspect pipe materials. When inspecting pipe materials, locating the defect is quite difficult. The traditional approach is to determine the defect location along the length direction and then find and eliminate the defect through circumferential grinding. This method is not only inefficient and increases time and labor costs significantly, but the dust generated during grinding also pollutes the environment and poses a threat to the physical and mental health of grinding personnel.

This ensures that the distance between each ultrasonic flaw detection head and the inner wall of the pipe is the same, thereby improving the accuracy of flaw detection. When the displacement sensors detect that the distance between the main body of the flaw detection device and different parts of the inner wall of the pipe is not the same, the position of the main body of the flaw detection device is adjusted by the three-axis adjustment components.

When damage is detected on the inner wall of the pipe, the controller activates the marking component. The nozzle in the marking component works and sprays the paint in the material box onto the inner wall of the pipe where the damage was detected, so as to accurately mark the location.

[0047] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0048] Example 1

[0049] like Figure 1-3 As shown, the ultrasonic automatic damage assessment and positioning spraying device includes:

[0050] Placement rack 2, which is suitable for placing the object to be tested;

[0051] The flaw detection device body 1 is provided with several circumferentially distributed ultrasonic flaw detection heads 9. The flaw detection device body 1 is provided with a controller. The ultrasonic flaw detection heads 9 are adapted to move towards the object to be tested, thereby detecting the object to be tested and feeding back the detection data to the controller.

[0052] The mobile platform 3 includes an X-axis adjustment component 4, a Y-axis adjustment component 5, and a Z-axis adjustment component 6.

[0053] The X-axis adjustment assembly 4, Y-axis adjustment assembly 5, and Z-axis adjustment assembly 6 are connected in sequence. The main body 1 of the flaw detection device is connected to the Z-axis adjustment assembly 6. The X-axis adjustment assembly 4, Y-axis adjustment assembly 5, and Z-axis adjustment assembly 6 are adapted to control the movement of the main body 1 of the flaw detection device in the X, Y, and Z axes, respectively.

[0054] like Figure 3-4 As shown, the X-axis adjustment assembly 4 includes an X-axis slide rail 41, an X-axis drive motor 42, an X-axis threaded rod 43, and an X-axis transmission sleeve 44.

[0055] The X-axis drive motor 42 is mounted on the X-axis slide rail 41, the X-axis threaded rod 43 is rotatably mounted inside the X-axis slide rail 41, the X-axis transmission sleeve 44 is assembled outside the X-axis threaded rod 43, the X-axis transmission sleeve 44 is connected to the Y-axis adjustment assembly 5, and the X-axis drive motor 42 is connected to the X-axis threaded rod 43 to drive the X-axis threaded rod 43 to rotate inside the X-axis slide rail 41, thereby driving the Y-axis adjustment assembly 5 to move along the axial direction of the X-axis threaded rod 43.

[0056] like Figure 3 , Figure 5 As shown, the Y-axis adjustment assembly 5 includes a Y-axis slide rail 51, a Y-axis drive motor 52, a Y-axis threaded rod 53, and a Y-axis transmission sleeve 54. The Y-axis slide rail 51 is connected to the X-axis transmission sleeve 44.

[0057] The Y-axis drive motor 52 is mounted on the Y-axis slide rail 51, the Y-axis threaded rod 53 is rotatably mounted inside the Y-axis slide rail 51, the Y-axis transmission sleeve 54 is assembled outside the Y-axis threaded rod 53, the Y-axis transmission sleeve 54 is connected to the Z-axis adjustment assembly 6, and the Y-axis drive motor 52 is connected to the Y-axis threaded rod 53 to drive the Y-axis threaded rod 53 to rotate inside the Y-axis slide rail 51, thereby driving the Z-axis adjustment assembly 6 to move along the axial direction of the Y-axis threaded rod 53.

[0058] like Figure 3-4 As shown, an auxiliary support component 7 is provided at the bottom of the Y-axis adjustment component 5. The auxiliary support component 7 includes a support slide rail 71 and a support rod 72.

[0059] The support rod 72 is set inside the support slide rail 71, and the Y-axis slide rail 51 is movably sleeved on the outside of the support rod 72. When the Y-axis slide rail 51 is driven to move by the X-axis transmission sleeve 44, it slides on the outer circumferential surface of the support rod 72.

[0060] like Figure 3 As shown, the Z-axis adjustment assembly 6 includes a Z-axis slide rail 61, a Z-axis drive motor 62, a Z-axis threaded rod 63, and a Z-axis transmission sleeve 64. The Z-axis slide rail 61 is connected to the Y-axis transmission sleeve 54.

[0061] Z-axis drive motor 62 is mounted on Z-axis slide rail 61, Z-axis threaded rod 63 is rotatably mounted inside Z-axis slide rail 61, Z-axis transmission sleeve 64 is assembled outside Z-axis threaded rod 63, Z-axis transmission sleeve 64 is connected to flaw detection device body 1, and Z-axis drive motor 62 is connected to Z-axis threaded rod 63 to drive Z-axis threaded rod 63 to rotate inside Z-axis slide rail 61, thereby driving flaw detection device body 1 to move along the axial direction of Z-axis threaded rod 63;

[0062] A counterweight plate 65 is connected to one side of the Z-axis slide rail 61.

[0063] like Figure 6-7 As shown, a number of circumferentially distributed displacement sensors 10 are provided on the outer circumferential surface of the flaw detection device body 1. The displacement sensors 10 are suitable for detecting the distance between the flaw detection device body 1 and the object being measured, and feeding the value back to the controller. The controller is suitable for controlling the X-axis adjustment component 4 and / or the Z-axis adjustment component 6 to adjust the position of the flaw detection device body 1 according to the data fed back by the displacement sensors 10.

[0064] The working principle of this embodiment is as follows:

[0065] When in use, the material to be tested is placed on the placement rack 2. The bottom of the placement rack 2 is equipped with a telescopic cylinder. The position and height of the material to be tested can be changed by the telescopic cylinder. The material to be tested can be a flat material or a pipe material. In this embodiment, a pipe material is used as an example.

[0066] After the pipe is fixed on the placement rack 2, the Y-axis drive motor 52 is started to drive the Y-axis threaded rod 53 to rotate. The Y-axis threaded rod 53 drives the externally mounted Y-axis transmission sleeve 54 to move along the axis of the Y-axis threaded rod 53. The direction of movement can be controlled by the forward and reverse rotation of the Y-axis drive motor 52. It should be noted that the threaded rod and the transmission sleeve can be assembled with ball nuts. When the transmission sleeve slides on the slide rail, the slide rail limits the transmission sleeve to prevent the transmission sleeve from rotating under the drive of the threaded rod. The linear movement driven by the threaded rod is existing technology and will not be described in detail here.

[0067] When the Y-axis transmission sleeve 54 moves, it will drive the Z-axis adjustment component 6 connected to it to move as a whole. The Z-axis adjustment component 6 is connected to the flaw detection device body 1, so that the Y-axis transmission sleeve 54 drives the flaw detection device body 1 to move. Under the drive of the Y-axis transmission sleeve 54, the flaw detection device body 1 extends into the inside of the pipe to be inspected. When it is inside the pipe, several circumferentially distributed ultrasonic flaw detection heads 9 installed on the flaw detection device body 1 work to detect the inner wall of the pipe. After the detection, the collected data is transmitted to the controller, so that the operator can obtain accurate values ​​to determine whether there is damage inside the pipe.

[0068] It should be noted that when using multiple circumferentially distributed ultrasonic flaw detectors 9 to inspect the inner wall of the pipe, ensuring that the distance between each ultrasonic flaw detector 9 and the inner wall of the pipe is the same helps to reduce detection errors, improve detection accuracy and reliability, and optimize the detection process. If the distance between each ultrasonic flaw detector 9 and the inner wall of the pipe is different, then the operating parameters of each ultrasonic flaw detector 9 (such as transmission power, receiving sensitivity, etc.) need to be adjusted to adapt to different detection distances.

[0069] Therefore, a circumferentially distributed displacement sensor 10 is also provided on the outer circumferential surface of the flaw detection device body 1. When the displacement sensor 10 is inside the pipe, it can monitor the distance between the flaw detection device body 1 and each part of the inner wall of the pipe in real time, that is, the distance between the ultrasonic flaw detection head 9 and the inner wall of the pipe, and feed the collected values ​​back to the controller. When the flaw detection device body 1 and the pipe are not on the same axis, the values ​​fed back by each displacement sensor 10 are also different. At this time, the controller starts the corresponding Z-axis adjustment component 6 and X-axis adjustment component 4 according to the values ​​fed back by the displacement sensor 10. The two components drive the flaw detection device body 1 to move and adjust in the Z-axis and X-axis directions to ensure that the flaw detection device body 1 and the pipe are on the same axis, that is, the distance between each ultrasonic flaw detection head 9 and the inner wall of the pipe is the same.

[0070] The working principle of the Z-axis adjustment assembly 6 and the X-axis adjustment assembly 4 is the same as that of the Y-axis adjustment assembly 5. The X-axis adjustment assembly 4 is located at the bottom layer. The X-axis transmission sleeve 44 in the X-axis adjustment assembly 4 drives the Y-axis adjustment assembly 5 to move in the X-axis direction. The Y-axis adjustment assembly 5 is located in the middle layer. The Y-axis transmission sleeve 54 drives the Z-axis adjustment assembly 6 to move in the Y-axis direction. The Z-axis adjustment assembly 6 is located at the top layer and is directly connected to the flaw detection device body 1. The Z-axis transmission sleeve 64 drives the flaw detection device body 1 to move in the Z-axis direction, thereby realizing the three-axis control movement of the flaw detection device body 1. It should be noted that encoders are installed on the X, Y, and Z axis drive motors to accurately control the distance the flaw detection device body 1 moves. At the same time, a counterweight plate 65 is connected to the Z-axis slide rail 61. The installation position of the counterweight plate 65 is opposite to that of the flaw detection device body 1. By adding the counterweight plate 65, the Z-axis adjustment assembly 6 is prevented from tilting due to the weight of the flaw detection device body 1.

[0071] In addition, since the Y-axis has the longest travel distance, the Y-axis slide rail 51 is relatively long. When the X-drive sleeve drives the Y-axis slide rail 51 to move as a whole, the support force on the Y-axis slide rail 51 is not strong. Therefore, an auxiliary support component 7 is provided. When the Y-axis slide rail 51 is driven to move, it will slide on the outer rail of the support rod 72. The support rod 72 and the support slide rail 71 play an auxiliary support role for the Y-axis slide rail 51.

[0072] Example 2

[0073] like Figure 6-7 As shown, this embodiment further includes the following structure based on embodiment one: a rotating mechanism 8 is provided on the Z-axis transmission sleeve 64, and the rotating mechanism 8 is connected to the flaw detection device body 1 to drive the flaw detection device body 1 to rotate.

[0074] like Figure 6-7 As shown, the rotating mechanism 8 includes a rotating base 81, a driving gear 84, a driven gear 82, and a rotating motor 85;

[0075] One end of the rotating seat 81 is rotatably mounted on the Z-axis transmission sleeve 64, and the other end of the rotating seat 81 is fixedly connected to the flaw detection device body 1.

[0076] A connecting plate 83 is connected to one side of the Z-axis transmission sleeve 64. A rotary motor 85 is mounted on the connecting plate 83. The rotary motor 85 is connected to the drive gear 84 to drive the drive gear 84 to rotate. The driven gear 82 is fixedly sleeved on the outer circumferential surface of the rotating seat 81. The drive gear 84 and the driven gear 82 mesh with each other.

[0077] like Figure 6-7 As shown, several marking components 11 are evenly distributed around the outer circumference of the main body 1 of the flaw detection device. The marking components 11 include a nozzle 1101, a conveying pipe 1102 and a material box 1103, and a pump is installed inside the material box 1103.

[0078] A number of nozzles 1101 correspond one-to-one with a number of ultrasonic flaw detectors 9, and the spray point of the nozzle 1101 and the ultrasonic emission point of the corresponding ultrasonic flaw detector 9 are at the same point.

[0079] The material box 1103 is disposed on the outer peripheral surface of the flaw detection device body 1, and the material box 1103 is connected to the corresponding nozzle 1101 through the conveying pipe 1102.

[0080] The ultrasonic flaw detector head 9 is adapted to transmit a signal to the controller after detecting damage to the test object. The controller is adapted to control the nozzle 1101 to spray a mark on the damaged area according to the signal fed back by the ultrasonic flaw detector head 9.

[0081] like Figure 6-7 As shown, a number of limiting sleeves 1104 corresponding to the marking component 11 are provided on the outer peripheral surface of the flaw detection device body 1. The conveying pipe 1102 passes through the corresponding limiting sleeve 1104, and the limiting sleeve 1104 is suitable for limiting the corresponding conveying pipe 1102.

[0082] The working principle of this embodiment is as follows:

[0083] The ultrasonic flaw detector heads 9, which are evenly distributed in a circle on the outer circumference of the flaw detector body 1, are used to detect flaws in the inner wall of the pipe. However, no matter how many ultrasonic flaw detector heads 9 are set, the installation gap will make it impossible to fully detect and cover the inner wall of the pipe. Therefore, a rotating mechanism 8 is set at the connection between the Z-axis transmission sleeve 64 and the flaw detector body 1. By rotating the flaw detector body 1 as a whole through the rotating mechanism 8, flaw detection without dead angles can be performed on the inner wall of the pipe through a limited number of ultrasonic flaw detector heads 9.

[0084] When the main body 1 of the flaw detection device needs to rotate, the rotary motor 85 in the connecting plate 83 is started to drive the drive gear 84 to rotate. The drive gear 84 drives the driven gear 82 to rotate through meshing with the driven gear 82. The driven gear 82 then drives the rotating seat 81 to rotate. Finally, the rotation of the main body 1 of the flaw detection device is achieved through the connection between the rotating seat 81 and the main body 1 of the flaw detection device. It should be noted that an encoder is set on the rotary motor 85 to accurately control the number of rotations of the main body 1 of the flaw detection device.

[0085] In addition, several circumferentially distributed marking components 11 are provided on the outer circumferential surface of the flaw detection device body 1. Each marking component 11 corresponds to each ultrasonic flaw detection head 9. The marking component 11 includes a nozzle 1101, a delivery pipe 1102, and a material box 1103. When the ultrasonic flaw detection head 9 detects damage at a certain point on the inner wall of the pipe, it feeds a signal back to the controller. The controller then controls the pump built into the material box 1103 to start working, delivering the paint in the material box 1103 to the nozzle 1101 through the delivery pipe 1102, and then spraying the paint out of the nozzle 1101 to the ultrasonic sensor. The flaw detector head 9 detects the location of damage and marks it to facilitate subsequent processing by operators. It should be noted that the spray point of the nozzle 1101 should be adjusted to be the same as the ultrasonic emission point of the ultrasonic flaw detector head 9 so as to accurately spray the mark on the detected problem area. At the same time, several limiting sleeves 1104 corresponding to each delivery pipe 1102 are also provided on the outer peripheral surface of the flaw detector body 1 to restrict the delivery pipe 1102 within the corresponding limiting sleeve 1104 and prevent the delivery pipe 1102 from shaking when the flaw detector body 1 rotates.

[0086] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
