Technical Field

[0001] This utility model relates to the field of weld inspection technology, and in particular to a weld inspection device for steel structure industrial plants. Background Technology

[0002] In steel structure buildings, steel structural components need to be welded together for fixation. However, defects such as cracks, lack of fusion, incomplete penetration, slag inclusions, and porosity are prone to occur during the welding process. Steel structure weld defects pose safety hazards in buildings. In order to prevent accidents, weld inspection must be carried out on the welded steel structural components. Through inspection, the structural safety and durability of steel structure industrial plants can be ensured.

[0003] Currently, ultrasonic flaw detectors are commonly used for inspecting welds in steel structures. These detectors are equipped with probes connected via signal lines. By sliding the probes across welds coated with couplant, the propagation characteristics of ultrasonic waves within the material are utilized to detect internal defects in the welds. The inspection results can be read from the display screen on the ultrasonic flaw detector.

[0004] However, the ultrasonic flaw detectors commonly found on the market still have certain shortcomings in use. During the use of existing ultrasonic flaw detectors, the staff needs to hold the instrument and walk between various welds to carry out the inspection work. The long-term hand-held operation increases the burden on the workers and easily leads to worker fatigue, which in turn affects the accuracy and efficiency of the inspection. In addition, the existing ultrasonic flaw detectors are not convenient to store the signal cable and probe, which further affects the portability of the instrument. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing detection devices requiring manual hand-held operation throughout the process, which easily leads to worker fatigue, affects detection accuracy and efficiency, and is also inconvenient to store signal cables and probes, affecting the portability of the device. Therefore, this invention proposes a weld detection device for steel structure industrial plants.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A weld inspection device for steel structure industrial plants includes an ultrasonic flaw detector. The receiving end of the ultrasonic flaw detector is connected to a probe via a signal line. The device also includes: an elastic band fixedly connected to the back of the ultrasonic flaw detector, wherein one end of the elastic band is rotatably connected to a fixing frame, and the other end of the elastic band is fitted onto the fixing frame and secured with Velcro, forming an elliptical cross-section binding structure; and a storage box fixedly connected to the ultrasonic flaw detector, with an opening at one end. A lid is rotatably connected to the opening of the storage box, and the lid and the storage box are secured by a snap-fit ​​mechanism, forming a storage space for wrapping the signal line and probe.

[0007] To facilitate limiting the position of the box lid, preferably, the buckle includes an elastic plate fixedly connected to the box lid, and one end of the elastic plate is fixedly connected to an arc-shaped locking tooth. The inner wall of the storage box is provided with an arc-shaped locking groove. When the box lid is rotated and closed, the arc-shaped locking tooth engages in the arc-shaped locking groove.

[0008] To facilitate the secure mounting of the elastic band onto the fixed frame, preferably, the hook and loop fastener includes a hook and loop hook side and a loop hook side that are fixedly connected to the elastic band, with the hook and loop hook side being adhered to the loop hook side.

[0009] To facilitate the storage of the signal cable in the storage box, preferably, a clearance opening is provided through one side of the storage box, and the width of the clearance opening is greater than the diameter of the signal cable.

[0010] To facilitate pulling apart the bonded elastic band, preferably, one end of the elastic band is fixedly connected to a pull head, and the pull head is provided with anti-slip texture.

[0011] To facilitate pushing open the lid after it has been positioned, preferably, a raised strip is fixedly connected to the lid, and the edges of the raised strip are rounded.

[0019] Example 1

[0020] Reference Figures 1-5 This utility model provides a weld inspection device for steel structure industrial plants, including an ultrasonic flaw detector 1, which can be a Perricone MINI-5 / MINI-10 or HK820 model. The receiving end of the ultrasonic flaw detector 1 is connected to a probe 3 via a signal line 2. It also includes an elastic band 4 fixedly connected to the back of the ultrasonic flaw detector 1. The elastic band 4 is made of a blend of nylon and spandex materials, ensuring good elasticity and improving durability. One end of the elastic band 4 is rotatably connected to a fixing frame 5, and the other end of the elastic band 4 is fitted onto the fixing frame 5 and fixed with Velcro, forming an elliptical cross-section binding structure. The binding structure can fix the ultrasonic flaw detector 1 to the worker's arm; the storage box 6 is fixedly connected to the ultrasonic flaw detector 1, and one end of the storage box 6 has an opening. A clearance opening 9 is opened through one side of the storage box 6, and the width of the clearance opening 9 is larger than the diameter of the signal line 2, so that the signal line 2 and the probe 3 can be easily stored in the storage box 6. The opening of the storage box 6 is rotatably connected to the lid 7. The lid 7 and the storage box 6 are limited by a buckle, so that the storage box 6 and the lid 7 form a storage space for wrapping the signal line 2 and the probe 3. A protrusion 11 is fixedly connected to the lid 7, and the edge of the protrusion 11 is rounded, which is used to push the lid 7 open after it is limited.

[0021] Specifically, during use, the ultrasonic flaw detector 1 can be fixedly strapped to the worker's arm using the elastic band 4, the fixing frame 5, and the Velcro. This eliminates the need for the worker to hold the ultrasonic flaw detector 1 at all times, freeing up the worker's fingers and palms, greatly improving the portability of the device, reducing worker fatigue, and helping to improve the accuracy and efficiency of weld inspection. The storage box 6, the lid 7, and the buckle facilitate the wrapping and storage of the signal cable 2 and the probe 3, eliminating the need for the worker to hold the signal cable 2 and the probe 3 at all times, thus freeing up the worker's hands. This allows the worker to more easily climb to welds at higher locations, further improving the portability of the device.

[0022] The buckle includes an elastic plate 8 fixedly connected to the lid 7. The elastic plate 8 is made of plastic. One end of the elastic plate 8 is fixedly connected to an arc-shaped locking tooth 81. The inner wall of the storage box 6 is provided with an arc-shaped locking groove 82. When the lid 7 is rotated and closed, the arc-shaped locking tooth 81 engages with the arc-shaped locking groove 82.

[0023] Specifically, in use, first turn the cover 7 to close it, so that the arc-shaped locking teeth 81 press against the edge of the storage box 6 and slide into the inner wall of the elastic plate 8. At the same time, the elastic plate 8 will bend under the pressure. As the cover 7 closes, the elastic plate 8 will elastically reset, so that the arc-shaped locking teeth 81 will engage in the arc-shaped locking groove 82. Through the cooperation of the elastic plate 8, the arc-shaped locking teeth 81 and the arc-shaped locking groove 82, the closed cover 7 can be limited, so that the cover 7 is not easy to loosen and open, thereby ensuring the storage effect of the signal line 2 and the probe 3.

[0024] The hook and loop fastener includes a hook and loop hook side 41 and a loop hook and loop hook side 42 that are fixedly connected to the elastic band 4, with the hook and loop hook side 41 being adhered to the loop hook and loop hook side 42.

[0025] Specifically, the hook side 41 and hook side 42 of the Velcro make it easy to fix the elastic band 4 onto the fixed frame 5, and also make it easy to adjust the tightness of the elastic band 4 so that the ultrasonic flaw detector 1 can be fixed on the worker's arm through the elastic band 4.

[0026] One end of the elastic band 4 is fixedly connected to a pull head 10, and the pull head 10 is provided with anti-slip texture.

[0027] Specifically, the pull tab 10 and the anti-slip texture make it easy to pull the bonded elastic band 4 apart, so that the hook side 41 of the hook and loop side 42 can be separated.

[0028] During use, the ultrasonic flaw detector 1 can be fixedly tied to the worker's arm by the cooperation of elastic band 4, fixing frame 5, hook and loop fastener 41 and hook and loop fastener 42. The worker does not need to hold the ultrasonic flaw detector 1 at all times, thus freeing the worker's fingers and palms, greatly improving the portability of the device, reducing worker fatigue, and helping to improve the accuracy and efficiency of weld inspection. Furthermore, the combination of the storage box 6, the lid 7, the arc-shaped locking teeth 81, and the arc-shaped locking groove 82 makes it easy to wrap and store the signal cable 2 and the probe 3, eliminating the need for workers to hold the signal cable 2 and the probe 3 throughout the process, thus freeing up the workers' hands. Workers can more easily climb to weld seams at higher locations, thereby further improving the portability of the device.

[0029] On the other hand, when the worker reaches the weld seam and needs to inspect it, he can forcefully push open the box cover 7 and take out the signal line 2 and probe 3. Then, he can place the probe 3 on the weld seam coated with coupling agent and slide it, and use the propagation characteristics of ultrasonic waves in the material to detect defects inside the weld seam. After the inspection is completed, the worker can raise his arm to read the inspection results on the display screen of the ultrasonic flaw detector 1.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
