Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a scanning and detection device for weld defects in steel structures. Background Technology

[0002] Steel structure welds are permanent connections formed between steel structure components through welding processes. They are the core nodes for load-bearing and force transmission in steel structures and are widely used in steel structure projects such as bridges, factories, high-rise buildings, pressure vessels, and ships. After steel structure welding, it is necessary to use testing devices to check for defects in the steel structure welds.

[0003] According to the patent application published on the Internet (authorization announcement number: CN217156329U), "This utility model relates to the technical field of detection devices, specifically a steel structure weld detection device. The device includes a frame, which comprises a steel pipe. A fixed column is connected through the steel pipe, and a connecting frame is fixedly connected to the surface of the fixed column. This utility model, through the cooperation of a screw, connecting plate, rollers, motor, signal receiver, and telescopic rod, allows operators to adjust the position of the connecting plate by moving the screw, thereby adjusting the position of the rollers. This ensures that the rollers can abut against steel pipes of different thicknesses, thus ensuring the device can abut against steel pipes of different sizes and ensuring its effectiveness." Regarding the above description, the applicant believes the following problems exist: The device, through the cooperation of a screw, connecting plate, rollers, motor, signal receiver, and telescopic rod, allows operators to adjust the position of the connecting plate and subsequently the rollers by moving the screw. This ensures the rollers can engage steel pipes of different thicknesses, guaranteeing the device's effectiveness. However, the roller engagement design relies on line contact between the metal rollers and the steel structure, limiting its ability to clamp steel structures with circular cross-sections (such as steel pipes). This results in poor adaptability. Furthermore, the steel structure is non-rotatable, allowing detection only of the weld seams at the top of the steel structure, leading to large blind spots in detection. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a steel structure weld defect scanning and detection device, which has the function of improving the stability of clamping steel structures and steel structures of different shapes, thereby improving the adaptability of the device and reducing the blind spot of steel structure detection.

[0005] The objective of this utility model is achieved through the following technical solution: A steel structure weld defect scanning and detection device includes a base, a motor, and a translation component. A control device is fixedly connected to the top of the base, and an alarm is fixedly connected to one side of the control device. The translation component is located on the outside of the base, and a motor is fixedly connected to one side of the base. A left- or right-hand screw is fixedly connected to the output end of the motor. A fixed block is threaded onto the left- or right-hand screw. A sliding rod is slidably connected inside the fixed block. A motor is fixedly connected to the inner wall of the fixed block. A gear is fixedly connected to the output end of the motor. A gear is meshed with one side of the gear. A rotating block is fixedly connected to one side of the gear. A motor is fixedly connected to the top of the rotating block. A left- or right-hand screw is fixedly connected to the output end of the motor. A clamping block is threaded onto the left- or right-hand screw. A rubber pad is fixedly connected to one side of the clamping block, and a sliding rod is slidably connected inside the clamping block.

[0006] In one optional embodiment, a through hole is provided on the rotating block, and a left- or right-hand screw is rotatably connected inside the rotating block through the through hole.

[0007] In one optional embodiment, when the second motor rotates clockwise, the two sets of clamping blocks move towards the middle of the second left and right rotating screws, and when the second motor rotates counterclockwise, the two sets of clamping blocks move towards both ends of the second left and right rotating screws.

[0008] In one optional embodiment, a second through hole is provided on the fixing block, and a gear is rotatably connected to the inside of the fixing block through the second through hole.

[0009] In one optional implementation, when motor one rotates clockwise, the two sets of fixed blocks move towards the middle of the left and right rotating screw one; when motor one rotates counterclockwise, the two sets of fixed blocks move towards the two ends of the left and right rotating screw one.

[0010] In one optional embodiment, the translation component includes a motor four fixedly connected to one side of the base, a rectangular lead screw fixedly connected to the output end of the motor four, a mounting bracket threadedly connected to the rectangular lead screw, a camera fixedly connected to the mounting bracket, and a sliding rod three slidably connected inside the mounting bracket.

[0011] In one optional embodiment, a through hole three is provided on the base, and a rectangular lead screw is rotatably connected to the inside of the base through the through hole three.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The user places one end of the steel structure inside the rotating block, and then starts the motor one through the control device to drive the left and right rotating screw one to rotate. This causes the left and right rotating screw one to move the two sets of fixing blocks to the middle of the left and right rotating screw one, so that the steel structure is clamped by the two sets of rotating blocks. At the same time, the second motor is started to drive the left and right rotating screw two to rotate. This causes the left and right rotating screw two to move the two sets of clamping blocks to the middle of the left and right rotating screw two, so that the clamping blocks clamp and fix the steel structure. Because the shape of the clamping block is set as V, it is convenient to clamp steel structures of different shapes, thereby improving the adaptability of the device and the stability of clamping and fixing. Because rubber pads are set, it is possible to avoid the clamping blocks from over-clamping and damaging the steel structure, thereby protecting the surface of the steel structure and preventing the steel structure from being scratched and indented.

[0013] 2. The translation component is activated to move the camera, allowing it to capture images of the top of the steel structure. This images of the steel structure's welds are converted into graphic signals and transmitted to the control device. The control device contains a detection module that uses image recognition to detect defects in the welds. If a defect is detected, the control device activates an alarm to alert the user. After the camera finishes capturing images of the steel structure's surface, the control device activates motor three, which drives gear one to rotate. Gear one then drives gear two, which in turn drives a rotating block, rotating the steel structure to a previously uncaptured area. The translation component is then used again to move the camera, thus inspecting the steel structure and reducing blind spots in the inspection process. Attached Figure Description

[0020] Please see Figures 1-5This utility model provides an embodiment of a steel structure weld defect scanning and detection device, including a base 1, a motor 401, and a translation component. A control device 2 is fixedly connected to the top of the base 1, and an alarm 3 is fixedly connected to one side of the control device 2. A translation component is provided on the outside of the base 1, and a motor 401 is fixedly connected to one side of the base 1. A left-right turning screw 403 is fixedly connected to the output end of the motor 401. A fixing block 402 is threaded onto the left-right turning screw 403. A sliding rod 404 is slidably connected inside the fixing block 402. A motor 410 is fixedly connected to the inner wall of the fixing block 402. A gear 411 is fixedly connected to the output end of the motor 410, and a gear 2 meshes with one side of the gear 411. 412, a rotating block 413 is fixedly connected to one side of gear 412. A motor 406 is fixedly connected to the top of the rotating block 413. A left-right helical screw 407 is fixedly connected to the output end of the motor 406. A clamping block 405 is threaded onto the left-right helical screw 407. A rubber pad 409 is fixedly connected to one side of the clamping block 405. A sliding rod 408 is slidably connected inside the clamping block 405. The user places one end of the steel structure into the rotating block 413, and then starts the motor 401 through the control device 2 to drive the left-right helical screw 403 to rotate. This causes the left-right helical screw 403 to drive the two sets of fixed blocks 402 to move towards the middle of the left-right helical screw 403, so that the steel structure is clamped by the two sets of rotating blocks 413. At the same time, the motor 401 is started. Motor 406 drives the left and right rotating lead screws 407 to rotate, which in turn causes the two sets of clamping blocks 405 to move towards the center of the lead screws 407. This clamping blocks 405 clamp and fix the steel structure in place. The V-shaped shape of the clamping blocks 405 facilitates clamping steel structures of different shapes, thus improving the adaptability and stability of the device. The inclusion of rubber pads 409 prevents over-clamping and damage to the steel structure, protecting its surface from scratches and indentations. Simultaneously, the translation component is activated, causing the camera 505 to move and capture an image of the top of the steel structure. The external shape of the steel structure weld is converted into a graphic signal and transmitted to the control device 2. The control device 2 is equipped with a detection module, which enables the control device 2 to detect whether there are defects in the weld of the steel structure through image recognition. If a defect is found, the control device 2 will activate the alarm 3 to sound an alarm, which helps to remind the user. When the camera 505 finishes capturing the surface of the steel structure, the control device 2 will start the motor 3 410 to drive the gear 1 411 to rotate, which in turn drives the gear 2 412 to rotate, which in turn drives the rotating block 413 to rotate, thereby rotating the steel structure to a blind spot that has not been captured. Then, the camera 505 is moved again by the translation component to inspect the steel structure, which helps to reduce the blind spots in the inspection of the steel structure.

[0021] In a preferred embodiment of this utility model, a through hole is provided on the rotating block 413, and the left and right rotating screw 407 is rotatably connected to the inside of the rotating block 413 through the through hole, which is conducive to the motor 406 driving the left and right rotating screw 407 to rotate, which is conducive to the left and right rotating screw 407 driving the clamping block 405 to move horizontally.

[0022] In a preferred embodiment of this utility model, when the second motor 406 rotates clockwise, the two sets of clamping blocks 405 move towards the middle of the left and right rotating screw 407. When the second motor 406 rotates counterclockwise, the two sets of clamping blocks 405 move towards both ends of the left and right rotating screw 407. This facilitates the clamping and fixing or loosening of the steel structure by the two sets of clamping blocks 405 through the forward and reverse motor 406.

[0023] In a preferred embodiment of this utility model, a through hole 2 is provided on the fixing block 402, and the gear 1 411 is rotatably connected to the inside of the fixing block 402 through the through hole 2, which is conducive to the motor 3 410 driving the gear 1 411 to rotate, which is conducive to the gear 1 411 driving the rotating block 413 to rotate through the transmission gear 2 412, which is conducive to driving the steel structure to rotate.

[0024] In a preferred embodiment of this utility model, when the motor 401 rotates clockwise, the two sets of fixing blocks 402 move towards the middle of the left and right rotating screw 403. When the motor 401 rotates counterclockwise, the two sets of fixing blocks 402 move towards the two ends of the left and right rotating screw 403, which facilitates the use of the forward and reverse motor 401 to clamp or release the steel structure by the rotating block 413.

[0025] Please see Figure 5 In this embodiment, the translation component includes a motor 501 fixedly connected to one side of the base 1, a rectangular lead screw 503 fixedly connected to the output end of the motor 501, a mounting bracket 502 threadedly connected to the rectangular lead screw 503, a camera 505 fixedly connected to the mounting bracket 502, and a sliding rod 504 slidably connected inside the mounting bracket 502. When it is necessary to inspect the steel structure, the control device 2 starts the motor 501 to drive the rectangular lead screw 503 to rotate, thereby causing the rectangular lead screw 503 to drive the mounting bracket 502 to translate, thereby causing the mounting bracket 502 to drive the camera 505 to translate, thereby causing the camera 505 to take pictures of the steel structure. The picture is taken when the mounting bracket 502 moves from one end of the rectangular lead screw 503 to the other end. After the steel structure rotates, the reverse motor 501 causes the rectangular lead screw 503 to drive the mounting bracket 502 to translate, thereby causing the camera 505 to take pictures of the blind spots of the steel structure.

[0026] In a preferred embodiment of this utility model, a through hole 3 is provided on the base 1, and the rectangular lead screw 503 is rotatably connected to the inside of the base 1 through the through hole 3, which is conducive to the motor 4 501 driving the rectangular lead screw 503 to rotate, which is conducive to the rectangular lead screw 503 driving the mounting bracket 502 to move horizontally.

[0027] During operation, the user places one end of the steel structure into the rotating block 413. Then, the control device 2 starts motor 401, which rotates the left and right rotating screw 403. This causes the left and right rotating screw 403 to move two sets of fixing blocks 402 towards the center of the left and right rotating screw 403, thus clamping the steel structure between the two sets of rotating blocks 413. Simultaneously, the control device 2 starts motor 406, which rotates the left and right rotating screw 407. This causes the left and right rotating screw 407 to move two sets of clamping blocks 405 towards the center of the left and right rotating screw 407, thus clamping and fixing the steel structure. The clamping blocks 405 are V-shaped, which is beneficial for clamping steel structures of different shapes, improving the adaptability and stability of the clamping and fixing. The presence of rubber pads 409 prevents the clamping blocks 405 from over-clamping and damaging the steel structure, protecting the surface of the steel structure and preventing scratches and indentations. Simultaneously, the control device 2 starts motor 406... 501 drives the rectangular lead screw 503 to rotate, which in turn drives the mounting bracket 502 to translate, which in turn drives the camera 505 to translate, allowing the camera 505 to capture an image of the top of the steel structure. This image of the steel structure's weld seam is converted into a graphic signal and transmitted to the control device 2. The control device 2 is equipped with a detection module, which uses image recognition to detect defects in the steel structure's weld seam. If a defect is detected, the control device 2 activates the alarm 3 to alert the user. After the camera 505 finishes capturing the surface of the steel structure, the control device 2 starts the motor 3 410, which drives the gear 1 411 to rotate. This gear 1 411 then drives the gear 2 412 to rotate, which in turn drives the rotating block 413 to rotate, thus rotating the steel structure to a blind spot that was not captured before. The reverse motor 4 501 then reverses the rectangular lead screw 503, which drives the mounting bracket 502 to translate, thereby detecting the blind spot of the steel structure and reducing blind spots in the inspection.

[0028] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0029] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
