Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure building technology, and in particular relates to a tool for inspecting the quality of steel structure welds. Background Technology
[0002] Steel structure weld quality inspection tools are specialized equipment or instruments used to assess the internal defects, appearance quality, and mechanical properties of welded joints in steel structures to ensure the safety and reliability of the welded structure. Their core function is to detect the integrity, continuity, and performance indicators of the weld using physical, chemical, or electromagnetic techniques. Data is collected from the weld using a matching detection probe, processed by the main unit, and displayed on a screen. This assists inspectors in judging internal defects and appearance quality, providing technical support for steel structure weld quality assessment.
[0003] In the weld quality inspection of steel structure engineering, the storage and retrieval of the testing probes significantly impacts overall operational safety. Inspectors frequently move between different workstations, and the lack of a dedicated, convenient fixing structure for the probes leads to haphazard placement and potential damage. Separating the testing equipment from the probes also results in tangling and pulling of the connecting cables. Therefore, we need to design a steel structure weld quality inspection tool with a cable management and probe placement structure. This structure can prevent tangling and pulling by organizing the connecting cables, ensuring stable equipment operation, providing a dedicated fixing point for the probes to reduce the risk of damage from haphazard placement, and allowing inspectors to easily retrieve and return the probes to their designated positions. This adaptable design accommodates multi-workstation movement and improves operational safety. Utility Model Content

Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0026] Figure 1-5 This invention illustrates a steel structure weld quality inspection tool according to an embodiment of the present invention. It includes a quality inspection instrument 1. A detection connection line 2 is electrically connected to the central axis on the right side of the quality inspection instrument 1 via an adapter interface. A detection probe 3 is connected to the end of the detection connection line 2 furthest from the quality inspection instrument 1. A fixing plate 5 is fixedly connected to the right side of the quality inspection instrument 1 via multiple bolts. A fixing rod 7 is provided on the right side of the fixing plate 5. Two symmetrical clamping blocks 9 are provided on the right side of the fixing rod 7. A connecting plate 10 is fixedly connected to the opposite side of each of the two clamping blocks 9. Two symmetrical round rods 11 are fixedly connected to the front and rear sides of the right side of the fixing plate 5. An L-shaped plate 15 is fixedly connected to the right side of the quality inspection instrument 1 via bolts. A U-shaped block 16 is fixedly connected to the top of the L-shaped plate 15 via bolts.
[0027] The above solution utilizes the cooperation of the fixing rod 7, the clamping block 9, and the connecting plate 10 to clamp and fix the detection probe 3, thereby making the detection probe 3 stably stand upright on the right side of the quality inspection instrument 1. It has the advantages of integrating wire harness organization and detection probe placement structure, organizing the detection connection wires to prevent tangling, providing a dedicated fixed position for the detection probe to reduce the risk of damage, adapting to multi-station mobile scenarios, facilitating quick access and return to the correct position, and improving operational safety.
[0028] Example 2: Reference Figure 5 Two symmetrical arc-shaped plates 6 are fixedly connected to the upper and lower sides of the right side of the fixed plate 5. The opposite side of the two arc-shaped plates 6 is fixedly connected to the fixed rod 7.
[0029] By adopting the above solution, the arc plate 6 serves to limit the movement of the fixed rod 7, ensuring that the fixed rod 7 will not wobble when the two rotating blocks 8 rotate on the surface of the fixed rod 7, thus improving the stability of the fixed rod 7 during use.
[0030] Example 2: Reference Figure 4 A pressure rod 12 is fixedly connected to the central axis on the left side of each of the two connecting plates 10. A spring 13 is sleeved on the surface of the round rod 11 and the pressure rod 12. The two ends of the spring 13 are welded to the fixed plate 5 and the connecting plate 10, respectively.
[0031] The above solution is adopted: by setting the spring 13, the elasticity of the spring 13 can flexibly relieve the force, so that the clamping force of the clamping block 9 is more uniform and has buffering, which not only fixes the detection probe 3 firmly in the detection position, but also avoids rigid compression damage to the detection probe shell and internal components. The pre-tightening force of the elastic element allows the clamp to complete the installation and removal of the detection probe 3 with a push and release, which is more convenient to use.
[0032] refer to Figure 5 Each of the two clamping blocks 9 has a clamping pad 14 installed on one side facing each other, and the two clamping pads 14 are in close contact with the detection probe 3 on the side facing each other.
[0033] The above solution is adopted: by setting the clamping pad 14, the rubber is soft and will not scratch the surface coating of the detection probe 3 when clamping the detection probe 3, thus protecting the detection accuracy from being affected. The surface of the clamping pad 14 has slight elasticity and roughness, which increases the friction when in contact with the detection probe 3, making the clamping more stable. The deformation characteristics of the rubber can make the clamping force more evenly distributed on the surface of the detection probe 3.
[0034] Working Principle: This utility model is suitable for multi-station mobile scenarios, ensuring stable testing. Before testing, the test probe 3 is placed between two clamping blocks 9. The elastic tension of the spring 13 is transmitted to the clamping blocks 9 through the pressure rod 12 and the connecting plate 10. The clamping pad 14 flexibly clamps and fixes the test probe, preventing displacement. The rubber clamping pad provides cushioning, shock absorption, scratch prevention, and increased friction, while the spring flexibly relieves force to avoid damage. After testing, the test connecting wire 2 is wrapped around the U-shaped block 16 and the seven-shaped plate 17 storage area. The rubber pad 18 increases friction and prevents slippage, while the arc-shaped plate 6 and the fixing rod 7 restrict cable movement. For the next test, the test connecting wire is released, and the spring and rotating block 8 work together to... The clamping block automatically resets to place the detection probe, fixing the detection probe in contact with the weld. The collected data is transmitted to the quality inspection instrument 1 via the detection connection line 2. After processing by the main unit, the display screen shows the results to assist in judgment. It has a portable carrying strap 4 for easy carrying. The detection probe has a dedicated position to prevent damage. The detection connection line is neat and does not tangle, which helps personnel switch between multiple workstations and improves efficiency. Spring buffer and clamping pad protection can cope with complex working conditions such as welding vibration and dust, ensuring stable detection data. Through mechanical clamping and elastic protection, combined with the neat structure of the wire harness, stable weld detection can be achieved in complex scenarios.
[0035] In summary, this steel structure weld quality inspection tool, through the coordinated use of the fixing rod 7, clamping block 9, and connecting plate 10, allows the two clamping blocks 9 to clamp and fix the inspection probe 3, thereby making the inspection probe 3 stably upright on the right side of the quality inspection instrument 1. It has the advantages of integrating wire harness organization and inspection probe placement structure, organizing the inspection connection wires to prevent tangling, providing a dedicated fixed position for the inspection probe to reduce the risk of damage, adapting to multi-station mobile scenarios, facilitating quick access and return to the correct position, and improving operational safety.
[0036] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
