[0026] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 3 The present invention provides a technical solution: a non-destructive testing bench for steel structure welds, including a testing bench 1, a support component 2 on the upper side of the testing bench 1, and a testing component 3 on one side of the support component 2. The support component 2 includes a first pad 21, and second pads 22 are provided on both sides of the first pad 21. The distance between the two second pads 22 and the first pad 21 is the same. The first pad 21 and the second pad 22 are used to support the steel structure components. In order to prevent the steel structure components from slipping off the upper side of the first pad 21 and the second pad 22, the first pad 21 and the second pad 22 are both downwardly concave arc-shaped plates.

[0028] Please see Figures 2-3As shown, a position adjustment component 23 is provided on the lower side of the first pad 21. The position adjustment component 23 is located on the upper side of the detection table 1. The position adjustment component 23 is used to adjust the distance between the two second pads 22 and the first pad 21. The position adjustment component 23 includes two pad blocks 231, which are symmetrically fixed on the lower side of the first pad 21 and fixed on the upper side of the detection table 1. Slider blocks 232 are symmetrically fixed on the lower side of the second pad 22. The slider 232 is slidably disposed on the upper side of the testing table 1. The pad 231 and the slider 232 are used to support the first pad 21 and the second pad 22 respectively. The upper side of the testing table 1 is fixedly provided with a slide rail for limiting the multiple sliders 232. The direction of the slide rail is perpendicular to the first pad 21. When the multiple sliders 232 slide, they drive the second pad 22 on their upper side to slide along the slide rail towards or away from the first pad 21, thereby adjusting the distance between the two second pads 22.

[0029] Please see Figures 2-3 As shown, toothed plates 233 are fixedly provided on the side of the two sliders 232 located on both sides of the two pads 231 that are close to each other. The two toothed plates 233 are symmetrically arranged between the two sliders 232. The toothed plates 233 slide through the middle of the pads 231. When the toothed plates 233 slide, they drive the sliders 232 on one side of them to slide. A gear 234 is meshed between the two toothed plates 233 that are close to each other. When the gear 234 rotates, it drives the two toothed plates 233 on its upper and lower sides to slide, and the two toothed plates 233 slide in opposite directions.

[0030] Please see Figures 2-3 As shown, a crossbar 235 is fixedly connected between the two gears 234. A motor 236 for driving the crossbar 235 to rotate is fixedly installed on one side of a pad 231. When adjusting the distance between the two second pads 22, the user starts the motor 236 to drive the crossbar 235 to rotate. At the same time, the crossbar 235 drives the two gears 234 to rotate. The gears 234 drive the toothed plates 233 on their upper and lower sides to slide. When the toothed plates 233 slide, they drive the slider 232 at one end to slide. At the same time, the slider 232 drives the second pad 22 on its upper side to move until the distance between the two second pads 22 is adjusted to be consistent with the length of the steel structure to be tested.

[0031] Please see Figures 2-4As shown, after adjusting the positions of the two No. 2 pads 22, the user places the steel structure on top of the No. 1 pad 21 and the two No. 2 pads 22, aligning both ends of the steel structure with one side of the two No. 2 pads 22. Clamping assemblies 24 are provided on the opposite sides of the two No. 2 pads 22. Each clamping assembly 24 includes an electric push rod 249, which is fixedly connected to the lower end of the No. 2 pad 22. A support plate 248 is fixedly connected to the output end of the electric push rod 249. The support plate 248 can be driven by the electric push rod 249. 48 moves. The surface of the support plate 248 has a through groove. The surface of the support plate 248 is provided with a rotating frame 246. The inner wall of the rotating frame 246 is slidably connected to the groove through a fixedly connected rotating shaft. When the support plate 248 moves, the rotating frame 246 starts to rotate. At the same time, the rotating shaft inside it slides up and down along the groove. The two sides of the rotating frame 246 are rotatably connected with fixing blocks 247. The fixing blocks 247 are fixedly connected to the surface of the second pad 22. The fixing blocks 247 can fix the rotating frame 246 so that it can only rotate.

[0032] A sliding plate 244 is slidably connected to the inner wall of the rotating frame 246. The surface of the sliding plate 244 is provided with protrusions. The sliding plate 244 is slidably connected to the inner wall of the rotating frame 246 via these protrusions. A fixed plate 242 is rotatably connected to one end of the sliding plate 244. When the sliding plate 244 moves up and down, the fixed plate 242 moves accordingly. A limiting plate 245 is slidably connected to the surface of the sliding plate 244 via a through-groove. A nut is threaded onto the surface of the limiting plate 245. The spring 243 can be adjusted via the limiting plate 245. The nut is in close contact with the sliding plate 244. When the nut is turned, the slide plate 244 can be tightly clamped by the nut and the limiting plate 245, so that the position of the limiting plate 245 can be easily adjusted. A rubber clamp 241 is rotatably connected to one side of the fixing plate 242. The rubber clamp 241 can increase the friction between the plate and the steel structure, making it easier to stabilize. A spring 243 is fixedly connected to the other side of the fixing plate 242. The other end of the spring 243 is fixed to the limiting plate 245. The spring 243 can keep the clamp 241 under force, thus maintaining close contact with the steel structure.

[0033] Please see Figures 2-5As shown, after placing the two clamping plates 241 at both ends of the steel structure, the position of the limiting plate 245 is adjusted by the nut. After adjustment, the slide plate 244 begins to slide down along the rotating frame 246. When the limiting plate 245 contacts the rotating frame 246, the slide plate 244 stops sliding. Then, the electric push rod 249 is activated, and the support plate 248 begins to move. During this process, the rotating frame 246 rotates and drives the slide plate 244 to rotate. At this time, the clamping plate 241 gradually approaches the steel structure. When the clamping plate 241 contacts the steel structure, the rotating frame 246 continues to rotate. At this time, the clamping plate 241 begins to rotate and the contact area with the steel structure gradually increases, thereby increasing the holding force. At the same time, the clamping plate 241 will pull the steel structure downward, so that the steel structure is always in contact with the surface of the first pad 21 and the two second pads 22, preventing the steel structure from slipping off the upper side of the first pad 21 and the two second pads 22.

[0034] Please see Figures 2-6 As shown, drive components 25 are provided at both ends of the first pad 21. A transmission belt 26 is rotatably mounted inside the first pad 21 and the two second pads 22. Several magnetic protrusions are fixedly mounted on the surface of the transmission belt 26. After the steel structure is placed on the first pad 21 and the two second pads 22, the magnetic protrusions on the surface of the transmission belt 26 immediately adhere to the bottom of the steel structure. Multiple transmission wheels 27 are rotatably mounted inside the first pad 21 and the second pads 22. These transmission wheels 27 are magnetic, and each transmission wheel 27 is in contact with the inner wall of its corresponding transmission belt 26. When the transmission wheels 27 rotate, they drive the multiple transmission belts 26 to rotate, thereby causing the steel structure to rotate and adjusting the placement angle of the steel structure.

[0035] Please see Figures 2-6 As shown, the drive assembly 25 includes a fixed rod 251, and a sliding rod 252 is provided on one side of the fixed rod 251. One end of the sliding rod 252 is slidably disposed inside the fixed rod 251. When the positions of the two second pads 22 are adjusted, the sliding rod 252 slides with the movement of the two second pads 22 to adjust the extension length of the sliding rod 252. The ends of the fixed rod 251 and the sliding rod 252 that are far apart from each other are fixedly connected to the center positions of the two transmission wheels 27 respectively. When the fixed rod 251 and the sliding rod 252 rotate, they drive the transmission wheels 27 at one end to rotate.

[0036] Please see Figures 2-7As shown, in order to enable the fixed rod 251 to drive the sliding rod 252 to rotate when it rotates, symmetrical locking blocks 253 are fixedly installed on the side wall of the sliding rod 252. The fixed rod 251 has a sliding groove inside that matches the locking blocks 253. When the fixed rod 251 rotates, it drives the two locking blocks 253 to rotate, and then drives the sliding rod 252 to rotate. A second motor 254 is fixedly installed on the side of a second pad 22 away from the first pad 21. The rotating shaft of the second motor 254 is fixedly positioned at the center of the corresponding transmission wheel 27. In the fixed connection, when adjusting the angle of the steel structure component, the user starts two No. 2 motors 254 to drive the transmission wheel 27 on one side to rotate. At the same time, the transmission wheel 27 drives the fixed rod 251 and slide rod 252 on one side to rotate. When the fixed rod 251 and slide rod 252 rotate, they drive the corresponding transmission wheel 27 to rotate. When multiple transmission wheels 27 rotate, they drive multiple transmission belts 26 to rotate. When the transmission belts 26 rotate, they drive the steel structure component to rotate, thereby adjusting the placement angle of the steel structure component.

[0037] Please see Figure 1 and Figure 8 As shown, the testing component 3 includes a base 31, which is fixedly mounted on the upper side of the testing platform 1. A support block 32 is rotatably mounted on the upper side of the base 31. A third motor 33 for driving the support block 32 to rotate is fixedly mounted inside the base 31. When testing the steel structure, the user first starts the third motor 33 to drive the support block 32 to rotate until the support block 32 is adjusted to a suitable angle. A first support arm 34 is rotatably mounted on the upper side of the support block 32. A fourth motor 35 for driving the first support arm 34 to rotate is fixedly mounted on one side of the support block 32. After adjusting the angle of the support block 32, the user starts the fourth motor 35 to drive the first support arm 34 to rotate to adjust the angle of the first support arm 34.

[0038] Please see Figure 1 and Figure 8As shown, a second support arm 36 is rotatably mounted on the end of the first support arm 34 away from the support block 32. A fifth motor 37 is fixedly mounted on one end of the first support arm 34 to drive the second support arm 36 to rotate. After adjusting the angle of the first support arm 34, the user starts the fifth motor 37 to drive the second support arm 36 to rotate and adjust the angle of the second support arm 36 until one end of the second support arm 36 is adjusted to be near the weld of the steel structure. A detection probe 38 is rotatably mounted on the end of the second support arm 36 away from the first support arm 34. A control panel 4 is fixedly mounted on the upper side of the detection platform 1. The control panel 4 is used to control the operation of the support assembly 2 and the detection assembly 3 and to display test data. The user controls the detection probe 38 to detect the weld of the steel structure and observes and records the detection data by operating the control panel 4. A micro motor 39 is fixedly mounted on one end of the second support arm 36 to drive the detection probe 38 to rotate. During the detection process, the user starts the micro motor 39 to drive the detection probe 38 to rotate and adjust the detection probe 38 to a suitable detection angle.

[0039] When this device is in operation, the steel structural component comes into contact with the transmission belt 26 and is simply fixed by the magnetic protrusions on its surface. The angle of the steel structural component can be adjusted by rotating multiple transmission belts 26. The clamping plate 241 in the holding assembly 24 can fix and compress the steel structural component, securing it in the support assembly. Subsequently, the steel structural component can be inspected as a whole by continuously adjusting and moving the detection probe 28 in the detection assembly 3. The device can comprehensively inspect and analyze weld quality without damaging the welded structure. Furthermore, to ensure the quality and safety of steel structure projects, the angle of the steel structural component can be adjusted, thereby improving inspection efficiency and accuracy. The entire device is controlled via a control panel. By adjusting the distance between the two secondary pads 22 and the primary pad 21, the device becomes highly versatile and suitable for steel structural components of various sizes, saving costs while facilitating inspection and making construction quality control easier.
