Description

Technical Field

[0001] This utility model relates to the field of weld inspection technology, specifically to a non-destructive testing device for steel structure welds. Background Technology

[0002] Steel structures are widely used due to their high strength, light weight, and fast construction speed. However, the quality of steel structures directly affects the safety and durability of buildings. Therefore, rigorous acceptance procedures are indispensable. Non-destructive testing (NDT) devices play a crucial role in steel structure acceptance, ensuring that weld quality meets design requirements and preventing safety accidents and structural damage caused by weld defects. A NDT device for steel structure welds is a device used to detect internal defects in steel structure welds. It is mainly applied to detect the presence of cracks, lack of fusion, and other defects in welds without damaging or affecting the performance of the inspected object.

[0003] A non-destructive testing device for steel structure welds, disclosed in CN215525642U, includes a base. Two fixed frames are positioned opposite each other on the top of the base. A first cylinder is fixedly connected to one side of each fixed frame, and a connecting plate is fixedly connected to one end of the piston rod of the first cylinder. A clamping plate is provided on one side of the connecting plate. By activating the two first cylinders, the piston rods of the first cylinders move the clamping plate, which in turn moves the clamping plate via a rotating shaft, bringing the two clamping plates closer together. This clamps and fixes the steel structure. When clamping the steel structure, the movable rods in contact with the steel structure compress a first spring and retract into the groove, while the movable rods not in contact with the steel structure remain around the steel structure, thus limiting the steel structure and increasing the fixing effect. This limiting method is applicable to different types of steel structures, thereby achieving the purpose of fixing the steel structure.

[0004] Existing weld inspection devices cannot be easily adjusted according to the size of steel structures when inspecting them. This makes it difficult to clamp and fix steel structures of different sizes, and also makes it difficult to adjust the position of the inspection components according to the location of the weld. Consequently, the devices cannot easily perform non-destructive testing on welds at different locations on steel structures of different sizes, which affects the accuracy of the inspection and the efficiency of weld inspection. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a non-destructive testing device for steel structure welds, so as to solve the problem in the prior art that the inability to conveniently adjust according to the size of the steel structure makes it difficult to conveniently test welds at different locations of steel structures of different sizes, which affects the accuracy of the test results.

The height of the ultrasonic testing instrument can be adjusted by rotating an adjusting screw. A second motor drives the steel structure components to rotate, enabling the ultrasonic testing instrument to inspect different locations within the weld. This ensures accurate test results and improves the efficiency of steel structure weld inspection.

[0034] Please see Figure 1-5This utility model provides a technical solution: a non-destructive testing device for steel structure welds, including a fixing mechanism 1 and a clamping mechanism 2, which is disposed on the top of the fixing mechanism 1 and is used to clamp and fix steel structure components of different sizes;

[0035] The inspection mechanism 3 is located on one side of the outer wall of the fixing mechanism 1 and is used to inspect the welds of the steel structure components.

[0036] By adjusting the fixing mechanism 1 and the clamping mechanism 2, steel structure components of different sizes can be clamped and fixed, enabling the device to inspect the welds of steel structure components of different sizes. At the same time, the inspection mechanism 3 can be easily adjusted according to the size of the steel structure component, so that the inspection mechanism 3 can stably inspect the welds of the steel structure component.

[0037] The clamping mechanism 2 includes two mounting plates 201. One end of one mounting plate 201 is provided with a second motor 202. Support plates 203 are fixedly installed at the bottom of opposite ends of the two mounting plates 201. Adjusting screws 205 are provided on the inner walls of the top of the two mounting plates 201. Pressure plates 206 are threaded onto the outer sides of the two adjusting screws 205.

[0038] During operation, the two ends of the steel structure component are placed on top of the two support plates 203 respectively. Then, by rotating the two adjusting screws 205, the two pressure plates 206 move along the outer walls of the adjacent adjusting screws 205, allowing the two pressure plates 206 to press and restrict the top ends of the steel structure component. Through the cooperation of the support plates 203 and the pressure plates 206, the clamping mechanism 2 can stably clamp and fix steel structure components of different sizes. The operation of the second motor 202 can drive one of the mounting plates 201 to rotate, which in turn drives the steel structure component to rotate, thereby enabling the inspection of different positions of the weld. The specific model of the second motor 202 is Y2-132S-4.

[0039] The testing mechanism 3 includes a fixed frame 301. A hydraulic cylinder 302 is provided on the outer wall of one end of the fixed frame 301. An adjusting screw 304 is provided on the inner wall of the top of the fixed frame 301. A third motor 305 is provided on the top of the adjusting screw 304. An ultrasonic detector 307 is provided on the outer side of the adjusting screw 304.

[0040] The hydraulic cylinder 302 moves the fixed frame 301 along one side of the outer wall of the fixing mechanism 1, thereby adjusting the lateral position of the ultrasonic detector 307 so that it is aligned with the weld seam on the same vertical plane. Simultaneously, the third motor 305 rotates the adjusting screw 304, moving the ultrasonic detector 307 along the outer wall of the adjusting screw 304, thus adjusting the height of the ultrasonic detector 307. This allows the ultrasonic detector 307 to stably inspect the weld seams of the steel structure components. Specifically, the hydraulic cylinder 302 is model SCS-N-TC-125, the third motor 305 is model Y2-112M-2, and the ultrasonic detector 307 is model BSM320A.

[0041] In this embodiment, the fixing mechanism 1 includes a fixed base plate 101, a fixed plate 102 is fixedly installed at one end of the top of the fixed base plate 101, a fixed rack 103 is fixedly installed at the middle position of the top of the fixed base plate 101, slide rails 104 are fixedly installed on both sides of the top of the fixed base plate 101, and a movable plate 105 is movably sleeved on the outer side of the end of the two slide rails 104 away from the fixed plate 102. A movable gear 106 that meshes with the fixed rack 103 is rotatably installed on the inner wall of the bottom of the movable plate 105, and a first motor 107 is provided on one side of the movable gear 106.

[0042] The first motor 107 operates, causing the movable gear 106 to rotate. Through the meshing action between the movable gear 106 and the fixed rack 103, the movable plate 105 moves along the outer wall of the two slide rails 104, allowing adjustment of the distance between the movable plate 105 and the fixed plate 102. This enables the fixing mechanism 1 to adapt to the installation and fixing of steel structure components of different lengths. The specific model of the first motor 107 is Y2-80M1-2.

[0043] In this embodiment, the inner walls of the fixed plate 102 and the movable plate 105 are rotatably connected to the two mounting plates 201 respectively. The inner walls of the top of the opposite ends of the two mounting plates 201 are provided with mounting grooves 204. The two mounting grooves 204 are rotatably connected to the two adjusting screws 205 respectively. The inner walls of the two mounting grooves 204 are movably connected to the outer walls of the two pressure plates 206 respectively.

[0044] The two mounting plates 201 can be installed and fixed respectively by the fixed plate 102 and the movable plate 105. At the same time, the fixed plate 102 can install and fix the second motor 202, so that the second motor 202 can stably drive the mounting plate 201 to rotate. Through the connection between the steel structure component and the mounting plate 201, the clamping mechanism 2 can stably drive the steel structure component to rotate, so that the device can stably detect different positions of the weld. The mounting groove 204 can install and fix the adjusting screw 205, so that the adjusting screw 205 can rotate inside the mounting groove 204. At the same time, the mounting groove 204 can limit the movement of the pressure plate 206, so that the pressure plate 206 remains stable during the adjustment process, so that the pressure plate 206 can stably press and limit the top of the steel structure component.

[0045] In this embodiment, one end of the outer wall of the fixed base plate 101 is fixedly connected to the hydraulic cylinder 302, the piston rod of the hydraulic cylinder 302 is fixedly connected to one end of the outer wall of the fixed frame 301, the inner wall of the top of the fixed frame 301 is provided with a movable groove 303, the inner wall of the movable groove 303 is rotatably connected to the adjusting screw 304, one side of the outer wall of the ultrasonic detector 307 is fixedly installed with a mounting base 306, the inner wall of the mounting base 306 is threadedly connected to the outer wall of the adjusting screw 304, the outer wall of the mounting base 306 is movably connected to the inner wall of the movable groove 303, the top of the fixed frame 301 is fixedly connected to the third motor 305, and the third motor 305 and the adjusting screw 304 are connected by an output shaft drive.

[0046] The fixed base plate 101 can be used to install and fix the hydraulic cylinder 302. When the hydraulic cylinder 302 works, the fixing frame 301 can move along one side of the outer wall of the fixed base plate 101. This allows for convenient adjustment of the horizontal position of the ultrasonic detector 307 according to the length of the steel structure component, enabling the ultrasonic detector 307 to be stably moved to the weld position of the steel structure component. At the same time, the third motor 305 drives the adjusting screw 304 to rotate, allowing the mounting base 306 to move along the inner wall of the movable groove 303 on its outer side. By installing and fixing the ultrasonic detector 307 through the mounting base 306, the height of the ultrasonic detector 307 can be stably adjusted, allowing the ultrasonic detector 307 to stably inspect the weld of the steel structure component and ensuring the accuracy of the inspection results.

[0047] In this embodiment, the center position of the ultrasonic detector 307 is at the same height as the middle position between the support plate 203 and the pressure plate 206. Rubber pads are provided on the opposite sides of the support plate 203 and the pressure plate 206. The length of the fixed rack 103 is the same as the length of the slide rail 104. The width of the fixed base plate 101 is the same as the width of the fixed plate 102 and the movable plate 105.

[0048] By adjusting the height of the ultrasonic testing instrument 307 to be positioned between the support plate 203 and the pressure plate 206, the ultrasonic testing instrument 307 can stably and clearly inspect the welds of the steel structure components, ensuring the accuracy of the inspection results. At the same time, the rubber pads on the inner sides of the support plate 203 and the pressure plate 206 can reduce wear between the steel structure components and the support plate 203 and the pressure plate 206, extending their service life. Meanwhile, the slide rail 104 can stably limit the movement of the movable plate 105, keeping it stable during adjustment. This allows the fixing mechanism 1 to stably clamp and fix steel structure components of different lengths.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
