Description

Technical Field

[0001] This utility model belongs to the field of steel component inspection technology, and in particular relates to a steel component flaw detection device. Background Technology

[0002] Steel components are individual basic parts made of steel through processes such as rolling, casting, welding, or bolting. They are the basic units that constitute a steel structure system. After production, steel components need to be inspected using flaw detection equipment.

[0003] Chinese patent discloses a non-destructive testing device for steel components (authorization announcement number CN215036850U). The patented technology includes a base, with two baffles on the top of the base. A base is welded between one side of the two baffles. Two sliding grooves are opened on the top of the base, and sliding plates are slidably connected to the inner walls of the two sliding grooves.

[0004] However, existing technologies have the following problems when used: Firstly, the height of the ultrasonic flaw detection component in existing flaw detection devices is fixed, and it is impossible to flexibly adjust the height according to the different sizes of the steel components to be inspected. Flaw detection operations can only be carried out at a fixed height, which may lead to inappropriate detection distances for some steel components, affecting the accuracy and applicability of flaw detection. Secondly, after the steel component is placed under the flaw detection device, there is a lack of convenient rotation and adjustment mechanism. It is impossible to adjust the orientation and angle of the steel component according to the flaw detection requirements, making it difficult for the device to cover all the detection positions of the steel component, which easily leads to flaw detection blind spots and incomplete detection. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a steel component flaw detection device that facilitates flaw detection of steel structures of different sizes, and enables comprehensive flaw detection of steel structures at different positions and angles, saving time and effort and improving work efficiency.

[0006] In view of this, the present invention provides a steel component flaw detection device, comprising: A support frame is provided, with a threaded rod installed at its upper end. A threaded ring 1 is detachably installed below the threaded rod, and a threaded ring 2 is detachably installed above the threaded rod. The upper end of the threaded rod passes through a connecting plate in a vertical direction, and the connecting plate is limited and clamped between the threaded ring 1 and the threaded ring 2. A connecting strip is provided at the lower end of the connecting plate, and a rack is installed at the lower end of the connecting strip. A mounting frame is slidably connected to the connecting strip. A rotatable gear is installed inside the mounting frame, and the gear meshes with the rack. An ultrasonic flaw detection mechanism is installed at the lower end of the mounting frame. The inner cavity of the support frame is equipped with a rotating disc at each end, and a telescopic rod is provided at the end of the disc, with an electromechanical claw installed at the end of the telescopic rod.

[0007] Furthermore, the lower end of the support frame is fixed with four pillars arranged in a rectangular array.

[0008] Furthermore, the upper end of the first threaded ring is provided with a first threaded hole, the upper end of the second threaded ring is provided with a second threaded hole, the upper end of the connecting plate is provided with a round hole, the top end of the threaded rod passes through the first threaded hole, the second threaded hole and the round hole, and the threaded rod is threadedly connected to the first threaded hole and the second threaded hole respectively.

[0009] Furthermore, the connecting strip has sliding grooves at both ends, and the mounting bracket has a groove at the top. The mounting plate is elastically connected to both ends of the groove, and a slider is installed at the rear end of the mounting plate. The slider is inserted into the sliding groove for sliding connection.

[0010] Furthermore, the inner wall of the first groove is provided with mounting grooves at both the front and rear ends, the inner wall of the mounting groove is provided with a through hole and the through hole communicates with the mounting groove, a spring is installed on the inner wall of the mounting groove and the spring is fixed to the second mounting plate, a connecting rod is fixed at the front end of the second mounting plate and the end of the connecting rod passes through the through hole.

[0011] Furthermore, a mounting plate is fixed to the end of the connecting rod away from the mounting plate two, and a handle is fixed to the front end of the mounting plate one.

[0012] Furthermore, the height of the second mounting plate is less than the height of the mounting groove opened in the mounting bracket.

[0013] Furthermore, a second groove is formed at the bottom of the inner wall of the first groove, and the second groove is connected to the first groove. A second motor is installed at the rear end of the mounting bracket, and the gear is connected to the drive end of the second motor.

[0014] Furthermore, a through slot is provided at the upper end of the support frame, and motors are respectively installed at both ends of the support frame, with the disc connected to the drive end of the motors.

[0015] Furthermore, the motors installed at both ends of the support frame are electrically connected to electronic synchronizers.

[0016] Compared with existing technologies, the steel component flaw detection device of this utility model has the following advantages: When flaw detection of a steel structure is required, this utility model uses an electric mechanical gripper to grasp and hold the steel structure. Then, depending on the size of the steel structure, rotating threaded ring one and threaded ring two allows the connecting plate and connecting strip to move up and down to a suitable height. Simultaneously, pulling the spring moves the slider and mounting plate two. The connecting strip is then inserted into groove one, the spring is released, and the slider is inserted into the slide groove. Starting motor one causes the steel structure to rotate, and simultaneously starting motor two causes the gears to rotate. The ultrasonic flaw detection mechanism can move as needed, achieving the effect of facilitating flaw detection of steel structures of different sizes, and enabling comprehensive flaw detection of different positions and angles of the steel structure. This saves time and effort and improves work efficiency. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] Please see Figures 1 to 8 The embodiments provided by this utility model are as follows: Example: A flaw detection device for steel components, comprising: Support frame 2, threaded rod 3 is installed on the upper end of support frame 2, threaded ring 14 is detachably installed below threaded rod 3, threaded ring 2 15 is detachably installed above threaded rod 3, threaded rod 3 penetrates connecting plate 4 vertically at the upper end, and connecting plate 4 is limited and clamped between threaded ring 14 and threaded ring 2 15, connecting strip 5 is provided at the lower end of connecting plate 4, rack 8 is installed at the lower end of connecting strip 5, mounting frame 6 is slidably connected to connecting strip 5, rotatable gear 19 is installed in mounting frame 6, and gear 19 is meshed with rack 8, ultrasonic flaw detection mechanism 7 is installed at the lower end of mounting frame 6; The inner cavity of the support frame 2 is equipped with a rotating disc 13 at both ends. The disc 13 is provided with a telescopic rod 12 at the end, and an electric mechanical claw 11 is installed at the end of the telescopic rod 12.

[0023] In the example of this application, the threaded rod 3 installed on the upper end of the support frame 2, together with the detachable threaded ring 14 and threaded ring 15, forms a limiting and clamping structure for the connecting plate 4. This allows the connecting plate 4 to be stably installed on the threaded rod 3, while also allowing for easy adjustment of the height of the connecting plate 4 by adjusting the positions of the threaded ring 14 and threaded ring 15 on the threaded rod 3 according to actual testing needs. The connecting strip 5 connected to the lower end of the connecting plate 4 and the rack 8 installed at the lower end of the connecting strip 5 will also adjust their height accordingly, ultimately achieving flexible adjustment of the height of the ultrasonic flaw detection mechanism 7 at the lower end of the mounting frame 6 to meet the testing height requirements of steel structures of different sizes. The sliding connection between the connecting strip 5 and the mounting bracket 6, along with the rotatable gear 19 within the mounting bracket 6 that meshes with the rack 8, provides reliable power transmission and guidance for the horizontal movement of the ultrasonic flaw detection mechanism 7. When the gear 19 rotates, its meshing with the rack 8 enables the mounting bracket 6 to slide smoothly along the connecting strip 5, allowing the ultrasonic flaw detection mechanism 7 to move horizontally to different positions on the steel structure as needed, ensuring that all areas of the steel structure can be inspected. Furthermore, the rotatable discs 13 installed at both ends of the inner cavity of the support frame 2, with telescopic rods 12 at their ends and electromechanical claws 11 installed at the ends of the telescopic rods 12, form a clamping and rotating mechanism for the steel structure. The electromechanical claws 11 can flexibly adjust the clamping force according to the size of the steel structure, achieving stable clamping of steel structures of different sizes and preventing displacement of the steel structure during inspection. At the same time, the rotation of the discs 13 can drive the clamped steel structure to rotate together, allowing the ultrasonic flaw detection mechanism 7 to inspect the steel structure from different angles, effectively avoiding blind spots and ensuring comprehensive inspection of the steel structure.

[0024] Furthermore, the lower end of the support frame 2 is fixed with four pillars 1 arranged in a rectangular array.

[0025] As a preferred example of this utility model, the rectangular array layout evenly distributes the overall weight of the device across the four support pillars 1, ensuring a relatively balanced pressure on each pillar 1 and effectively preventing damage to the pillar 1 or tilting of the device due to excessive local stress. The four support pillars 1 work together to provide more stable and reliable support for the support frame 2, thereby ensuring that components such as the threaded rod 3, connecting plate 4, ultrasonic flaw detection mechanism 7, disk 13, telescopic rod 12, and electromechanical gripper 11 mounted on the support frame 2 can operate in a stable environment. Whether the ultrasonic flaw detection mechanism 7 is performing height adjustment and horizontal movement testing, or the electromechanical gripper 11 is clamping and rotating the steel structure for testing, the four support pillars 1 can effectively resist vibrations and external force interference generated during device operation, maintaining the overall stability of the device, ensuring the smooth progress of testing, and improving the accuracy of the test results.

[0026] Furthermore, the upper end of the threaded ring 14 is provided with a threaded hole 1, the upper end of the threaded ring 25 is provided with a threaded hole 2, the upper end of the connecting plate 4 is provided with a round hole, and the top end of the threaded rod 3 passes through the threaded hole 1, the threaded hole 2 and the round hole, and the threaded rod 3 is threadedly connected to the threaded hole 1 and the threaded hole 2 respectively.

[0027] As a preferred example of this utility model, the threaded hole one at the upper end of the threaded ring one 14, the threaded hole two at the upper end of the threaded ring two 15, and the round hole at the upper end of the connecting plate 4 provide installation positions for the through connection of the threaded rod 3. The top end of the threaded rod 3 passes through the threaded hole one, the threaded hole two, and the round hole, and is threadedly connected to the threaded hole one and the threaded hole two, respectively. The threaded connection method allows the threaded ring one 14 and the threaded ring two 15 to be firmly fixed on the threaded rod 3, while also making it easy for the operator to adjust their positions on the threaded rod 3 by rotating the threaded ring one 14 and the threaded ring two 15. Since the connecting plate 4 is clamped between threaded ring 14 and threaded ring 15, the height of the connecting plate 4 can be easily adjusted by changing the position of the two threaded rings. The threaded connection has excellent self-locking performance. Once threaded ring 14 and threaded ring 15 are adjusted to the appropriate position and tightened, they effectively prevent loosening of the threaded rings due to vibration or other factors during device operation, thus ensuring the stability of the connecting plate 4's position. This ensures that the connecting strip 5, rack 8, mounting bracket 6, and ultrasonic flaw detection mechanism 7 installed below the connecting plate 4 can be stably positioned at the set detection height, providing strong support for the accuracy of the detection work. At the same time, the threaded connection structure also makes the disassembly and installation of each component more convenient. When maintenance or replacement of the connecting plate 4, threaded ring 14, or threaded ring 15 is required, simply rotate the threaded ring to remove it from the threaded rod 3, reducing the difficulty of maintenance operations.

[0028] Furthermore, the connecting strip 5 has grooves 17 at both ends, and the mounting bracket 6 has a groove 22 at the top. The mounting plate 24 is elastically connected to the front and rear ends of the groove 22. The slider 23 is installed at the rear end of the mounting plate 24 and is inserted into the groove 17 for sliding connection.

[0029] As a preferred example of this utility model, the sliding grooves 17 at both ends of the connecting strip 5 cooperate with the slider 23 installed at the rear end of the mounting plate 24, which is elastically connected to both ends of the mounting bracket 6 in the groove 22 at the upper end. The slider 23 is inserted into the sliding groove 17 and achieves a sliding connection. The sliding fit structure can limit the sliding direction of the mounting bracket 6, ensuring that the mounting bracket 6 will not deviate or shake during its movement along the connecting strip 5, thereby ensuring that the ultrasonic flaw detection mechanism 7 can move smoothly along the preset detection path and improve the accuracy of the detection position.

[0030] The elastic connection of mounting plate 24 allows slider 23 to fit tightly against the inner wall of slide groove 17, reducing gaps during sliding and further improving sliding stability and smoothness.

[0031] Furthermore, mounting grooves 28 are respectively provided at the front and rear ends of the inner wall of the first groove 22. A through hole 26 is provided in the inner wall of the mounting groove 28, and the through hole 26 communicates with the mounting groove 28. A spring 27 is installed in the inner wall of the mounting groove 28, and the spring 27 is fixed to the second mounting plate 24. A connecting rod 25 is fixed at the front end of the second mounting plate 24, and the end of the connecting rod 25 passes through the through hole 26.

[0032] As a preferred example of this utility model, the mounting grooves 28 opened at both ends of the inner wall of the first groove 22 provide suitable space for the installation of the spring 27. The through hole 26 opened in the inner wall of the mounting groove 28 communicates with the mounting groove 28, so that the connecting rod 25 fixed at the front end of the second mounting plate 24 can pass smoothly through and extend to the outside of the mounting frame 6. The spring 27 installed in the inner wall of the mounting groove 28 is fixedly connected to the second mounting plate 24. The elastic force of the spring 27 can continuously act on the second mounting plate 24, so that the slider 23 at the rear end of the second mounting plate 24 is always in contact with the sliding groove 17 of the connecting strip 5, effectively eliminating the gap between the slider 23 and the sliding groove 17, ensuring the stability of the mounting frame 6 during the sliding process, avoiding sliding displacement caused by the gap, and thus ensuring the accuracy of the detection position of the ultrasonic flaw detection mechanism 7. The connecting rod 25 not only guides the movement of the second mounting plate 24 but also facilitates the operator's adjustment of its position. When the mounting bracket 6 needs to be removed from the connecting strip 5, the operator can pull the connecting rod 25 to move the second mounting plate 24 into the mounting groove 28, while simultaneously compressing the spring 27 to disengage the slider 23 from the slide groove 17, thus separating the mounting bracket 6 from the connecting strip 5. This makes disassembly more convenient and labor-saving, eliminating the need for complex tools, reducing operational difficulty, and improving disassembly efficiency. During installation, simply align the groove 22 of the mounting bracket 6 with the connecting strip 5, release the connecting rod 25, and under the elastic restoring force of the spring 27, the second mounting plate 24 will automatically reset, causing the slider 23 to insert into the slide groove 17, completing the connection between the mounting bracket 6 and the connecting strip 5. The entire installation process is simple and efficient.

[0033] Furthermore, a mounting plate 21 is fixed to the end of the connecting rod 25 away from the mounting plate 24, and a handle 20 is fixed to the front end of the mounting plate 21.

[0034] As a preferred example of this utility model, the handle 20 is configured to provide an easy gripping area for the operator. Compared to directly pulling the connecting rod 25, the handle 20 can increase the contact area between the hand and the operating component, distribute the pressure on the hand, and avoid hand discomfort or slippage caused by the small diameter of the connecting rod 25 during the pulling process. This allows the operator to apply pulling or pushing force more easily and stably to adjust the position of the connecting rod 25. The mounting plate 21 serves to connect and secure the handle 20 to the connecting rod 25, ensuring that the handle 20 is firmly installed on the connecting rod 25 and will not loosen or fall off during operation, thus guaranteeing operational safety and reliability. When it is necessary to disassemble the mounting bracket 6, the operator only needs to hold the handle 20, and the connecting rod 25 will move through the mounting plate 21, thereby pulling the mounting plate 24 to compress the spring 27, causing the slider 23 to exit the slide groove 17, making the operation more effortless and convenient. When installing the mounting bracket 6, after releasing the handle 20, the components can smoothly return to their original positions under the action of the spring 27, and the slider 23 inserts into the slide groove 17 to complete the connection.

[0035] Furthermore, the height of mounting plate 24 is less than the height of the mounting slot 28 opened inside mounting bracket 6.

[0036] As a preferred example of this utility model, since the second mounting plate 24 needs to extend and retract under the action of the spring 27 to drive the slider 23 to insert or exit the groove 17 of the connecting strip 5, if the height of the second mounting plate 24 is the same as or greater than the height of the mounting groove 28, the second mounting plate 24 will not be able to move freely in the mounting groove 28, and the extension and retraction function of the spring 27 will also be restricted, which will cause the slider 23 to be unable to smoothly cooperate or separate from the groove 17, affecting the disassembly and installation operations of the mounting bracket 6 and the connecting strip 5. The height of mounting plate 24 is less than the height of mounting groove 28, giving it sufficient room to move within the groove and allowing it to move freely back and forth under the drive of spring 27. When the operator pulls handle 20 to move mounting plate 24 into mounting groove 28 via connecting rod 25, mounting plate 24 can smoothly compress spring 27 and penetrate deep into mounting groove 28, ensuring that slider 23 can completely exit slide groove 17, achieving complete separation of mounting bracket 6 and connecting strip 5. When handle 20 is released, under the elastic restoring force of spring 27, mounting plate 24 can smoothly move out of mounting groove 28, causing slider 23 to accurately insert into slide groove 17, completing the stable connection between mounting bracket 6 and connecting strip 5.

[0037] Furthermore, a second groove 18 is provided at the bottom of the inner wall of the first groove 22, and the second groove 18 is connected to the first groove 22. A second motor 16 is installed at the rear end of the mounting bracket 6, and a gear 19 is connected to the drive end of the second motor 16.

[0038] As a preferred example of this utility model, the opening of the second groove 18 can accommodate a part of the gear 19, so that the gear 19 can be smoothly installed inside the mounting bracket 6 and maintain a good meshing state with the rack 8 at the lower end of the connecting strip 5. This avoids the situation where the gear 19 and the rack 8 are not meshed tightly or cannot mesh due to space limitations, and ensures that power can be stably and efficiently transmitted from the gear 19 to the rack 8. Motor 16, acting as a power source, provides a continuous and stable driving force for the rotation of gear 19. Motor 16 can control the rotational speed and angle of gear 19, and thus, through the meshing of gear 19 and rack 8, control the moving speed and distance of mounting frame 6 along connecting bar 5. Ultrasonic flaw detection mechanism 7 can move to the designated detection position on the steel structure at a uniform speed according to a preset detection program, avoiding detection position deviations caused by uneven force and unstable speed during manual operation, effectively improving the accuracy and consistency of detection results. The motor 16 drives the gear 19 to rotate, which in turn moves the mounting frame 6 and the ultrasonic flaw detection mechanism 7 automatically. This greatly reduces the labor intensity of the operators and improves the efficiency of the inspection work. It is especially suitable for long-term and large-scale inspection of large steel structures, which can effectively shorten the inspection time and improve the overall efficiency of the inspection work.

[0039] Furthermore, a through slot 9 is provided at the upper end of the support frame 2, and motors 10 are installed at both ends of the support frame 2 respectively, with the disc 13 connected to the drive end of the motors 10.

[0040] As a preferred example of this utility model, the through slot 9 ensures that the disc 13 is not obstructed by the support frame 2 during rotation. It also provides sufficient operating space for the extension and retraction of the telescopic rod 12 and the clamping of the steel structure by the electromechanical claw 11. This avoids situations where the steel structure cannot be clamped smoothly or the rotation angle is limited due to space constraints, thus ensuring the flexibility and comprehensiveness of the inspection work. Motor 10 serves as the power source, providing a stable and reliable driving force for the rotation of disk 13. By driving disk 13 to rotate via motor 10, the telescopic rod 12 at the end of disk 13 and the electromechanical gripper 11 rotate together, thereby achieving the rotation of the steel structure held by the electromechanical gripper 11. Motor 10 can control the rotation speed and angle of disk 13, ensuring that the steel structure can rotate to the specified angle at a uniform speed according to the preset inspection requirements. This allows the ultrasonic flaw detection mechanism 7 to perform comprehensive and detailed inspection of all parts of the steel structure, effectively avoiding the existence of blind spots in the inspection.

[0041] Furthermore, the motors 10 installed at both ends of the support frame 2 are electrically connected to electronic synchronizers.

[0042] As a preferred example of this utility model, the electronic synchronizer enables the synchronous operation of the two motors 10, which is the key to ensuring the stable and uniform rotation of the steel structure.

[0043] In this embodiment, when flaw detection of a steel structure is required, the operator first activates the electromechanical claws 11 located at both ends of the inner cavity of the support frame 2. The electromechanical claws 11 automatically adjust the clamping angle and force according to the specific shape and size of the steel structure to be inspected, thus gripping the steel structure. During this process, the telescopic rod 12 connected to the electromechanical claws 11 flexibly extends and retracts according to the position of the steel structure, assisting the electromechanical claws 11 in positioning the clamping point and avoiding subsequent inspection due to clamping position deviation. It also provides suitable clamping space for steel structures of different sizes, preventing displacement or shaking during the inspection process. After clamping and fixing the steel structure, the operator will adjust the height of the ultrasonic flaw detection mechanism 7 according to the dimensions of the steel structure. The operator changes the vertical position of the threaded ring 14 and threaded ring 15 on the threaded rod 3 by rotating the threaded ring 14 and threaded ring 15. Since the connecting plate 4 is clamped between the threaded ring 14 and threaded ring 15, the adjustment of the position of the threaded ring 14 and threaded ring 15 will directly drive the connecting plate 4 to move up and down along the vertical direction of the threaded rod 3. The connecting strip 5 fixedly connected to the lower end of the connecting plate 4 will move synchronously with the connecting plate 4. The rack 8 installed at the lower end of the connecting strip 5 and the mounting bracket 6 slidably connected to the connecting strip 5 will also change height accordingly, realizing the height adjustment of the ultrasonic flaw detection mechanism 7 at the lower end of the mounting bracket 6, until the ultrasonic flaw detection mechanism 7 moves to a position that matches the height of the part of the steel structure to be inspected, laying the foundation for subsequent horizontal inspection movement. If the connection between the mounting bracket 6 and the connecting strip 5 needs to be adjusted before testing, or if a different specification of ultrasonic flaw detection mechanism 7 needs to be replaced, this must be achieved by operating the elastic connection structure on the mounting bracket 6. The operator will grasp the handle 20 at the front end of the mounting plate 1 21 and pull the handle 20 outward. The handle 20 will move the mounting plate 1 21, which is fixed to it, and the mounting plate 1 21 will then pull the mounting plate 24 through the connecting rod 25. At this time, the spring 27 installed in the mounting groove 28 will be compressed due to the movement of the mounting plate 24, and the slider 23 at the rear end of the mounting plate 24 will move into the mounting groove 28 with the mounting plate 24, gradually disengaging from the sliding grooves 17 at both ends of the connecting strip 5. After the slider 23 has completely exited the groove 17, the mounting bracket 6 can be removed from the connecting strip 5. If reinstallation is required, align the groove 22 at the upper end of the mounting bracket 6 with the connecting strip 5, and slowly release the handle 20. The compressed spring 27 will release its elastic restoring force, pushing the mounting plate 24 to move inward toward the groove 22. The slider 23 at the rear end of the mounting plate 24 will automatically insert into the groove 17 of the connecting strip 5, completing the sliding connection between the mounting bracket 6 and the connecting strip 5. This ensures that the mounting bracket 6 can slide stably along the connecting strip 5, and the tight fit between the slider 23 and the groove 17 can effectively prevent the mounting bracket 6 from shifting during sliding. Once all preparations are complete, the motors 10 installed at both ends of the support frame 2 are started first. The drive end of the motor 10 drives the connected disc 13 to rotate. The telescopic rod 12 at the end of the disc 13 and the steel structure held by the electromechanical claw 11 will rotate synchronously with the disc 13. Since the two motors 10 are electrically connected to electronic synchronizers, the electronic synchronizers ensure that the rotation speed and rotation angle of the two motors 10 are completely consistent, thus ensuring that the steel structure remains stable during rotation and will not tilt or twist due to asynchronous rotation at both ends. This ensures that all circumferential surfaces or sides of the steel structure are evenly exposed within the detection range of the ultrasonic flaw detection mechanism 7, effectively eliminating blind spots in the detection. Simultaneously, motor 16 at the rear of mounting bracket 6 is activated, driving gear 19, which is installed in groove 18, to rotate. Since gear 19 meshes with rack 8 at the lower end of connecting strip 5, the rotation of gear 19 translates into horizontal movement of mounting bracket 6 along the length of connecting strip 5. During this movement, slider 23 in groove 22 at the upper end of mounting bracket 6 slides smoothly along the groove 17 of connecting strip 5, providing guidance for the movement of mounting bracket 6 and ensuring it does not deviate from the preset detection path. Ultrasonic flaw detection mechanism 7 at the lower end of mounting bracket 6 moves horizontally synchronously with mounting bracket 6, performing flaw detection at different axial positions of the steel structure while it rotates. Through the coordinated operation of motor 10 driving the steel structure to rotate and motor 26 driving the ultrasonic flaw detection mechanism 7 to move horizontally, comprehensive detection of surface and internal defects of the steel structure is achieved, ensuring the integrity and accuracy of the detection results. This approach facilitates flaw detection of steel structures of different sizes, allows for comprehensive flaw detection at different positions and angles, saves time and effort, and improves work efficiency.
