Description

Technical Field

[0001] This application relates to the field of ultrasonic testing, and more specifically, to a non-destructive testing instrument for steel structure testing. Background Technology

[0002] Non-destructive testing (NDT) is a technology that detects defects in an object without compromising its performance. NDT instruments for steel structures operate based on acoustic, optical, magnetic, and electrical properties, enabling them to detect internal and surface defects and determine their size and location. They are widely used in steel structure engineering and are currently a crucial means of ensuring the quality and safety of steel structure projects.

[0003] Existing equipment suffers from various limitations during ultrasonic wave propagation, such as material inhomogeneity and shape complexity. This necessitates accurate signal interpretation and defect assessment by operators. Inexperienced operators may misjudge or miss defects, thus affecting the accuracy of the detection results.

[0004] Currently, there is no non-destructive testing instrument for steel structure inspection that can solve the problems that the surface roughness and shape of steel structure components may affect the accuracy of the test results, and that cannot perform uniform testing on curved steel. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide a non-destructive testing instrument for steel structure inspection, comprising: a platform, with bases installed at the four corners of the lower surface of the platform, a conveyor belt installed on the upper surface of the platform, a guide rail installed on the upper surface of the platform, a slider inserted inside the guide rail, a lifting slide rail installed on the upper surface of the slider, a motor installed on the upper surface of the lifting slide rail, and a flywheel rotatably connected to one side of the motor.

[0007] During the working or installation process, due to the function of the guide rail structure, it has the function of installing a steel structure detector placement frame that can move within the guide rail. The motor can drive the flywheel to realize the lifting and lowering of the detection equipment. The main detection equipment is installed in it, making the ultrasonic detection of steel structures more accurate.

[0008] Furthermore, a chain is rotatably connected to the surface of the flywheel, and a protective plate is sleeved on the lower part of the chain.

[0009] Furthermore, a top frame is inserted into the middle of the lifting slide rail, and a lifting push rod is installed at one end of the lower surface of the top frame.

[0010] Furthermore, a lever is installed on the upper surface of the top frame, and a pulley is installed on the lower surface of the lifting push rod.

[0011] Furthermore, an electric push rod is installed on the lower surface of the top frame, and an ultrasonic probe is installed on the lower surface of the electric push rod.

[0012] Furthermore, a scraper is mounted on the lower surface of the electric push rod, and an extrusion device assembly is mounted on the lower surface of the electric push rod.

[0013] Furthermore, a vertical arm is mounted on the upper surface of the platform, and a central shaft is mounted in the middle of the vertical arm.

[0014] Furthermore, a scraper is installed in the middle of the vertical arm, and a collection box is installed in the middle of the vertical arm.

[0015] Furthermore, a retractor is rotatably connected to the surface of the central shaft, and the number of the retractors is ten.

[0016] The beneficial effects of this application are: it provides a specific non-destructive testing instrument for steel structure testing that can solve the problem that factors such as the surface roughness and shape of steel structure components may affect the accuracy of the test results and that it is impossible to uniformly test curved steel.

[0017] By inserting a slider into the guide rail, a lifting slide rail is fixedly installed on the upper surface of the slider. The detection equipment is installed inside the lifting slide rail. This design allows the detection mechanism to move in a parallel direction on the upper surface of the platform. A motor is installed on the upper surface of the lifting guide rail. The motor drives the flywheel of the meshing chain to rotate, which engages the lever of the lifting top frame with the teeth of the chain to achieve lifting. To prevent unbalanced lifting, a lifting push rod is installed at the other end of the lower surface of the top frame. The lifting push rod can move with the slider, and a pulley is installed on the lower surface of the lifting push rod. This design avoids the problem of unbalanced weight distribution.

[0018] By installing multiple sets of electric push rods on the lower surface of the top frame, with ultrasonic detectors mounted at the bottom of the push rods, the electric push rods can drive the ultrasonic detectors to rise and fall to match the shape of the metal object to be detected. This design allows the equipment to be used not only for sample testing, but also for applications such as finished product block testing to predict the lifespan of existing structures or other uses, greatly expanding the equipment's applicability. To prevent reduced detection accuracy when testing some metal objects due to surface roughness, a scraper and an extrusion assembly are installed on one side of the ultrasonic detector along the conveyor belt's conveying direction. The extrusion assembly applies coupling agent to the object being tested, and the scraper, which can adapt to different shaped rubber materials, spreads the coupling agent. Then, the ultrasonic detector can detect the object to obtain a more accurate image of its internal structure.

[0019] The coupling agent remaining from the previous step can be cleaned by using the booms. The cleaning method involves installing a central shaft in the middle of the two booms. The central shaft drives the retractor to rotate. The retractor can swing freely, but it has a certain amount of damping to prevent it from deviating due to the torque of the central shaft. The retractor can clean the coupling agent remaining from the previous step by rotating the small conveyor belt on its surface. After cleaning, the coupling agent left in the retractor will fall into the collection box when it passes through the scraper. The operator needs to clean the collection box regularly.

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] As a preferred embodiment of this example, Figures 1-4As shown, the system includes: a platform 1, with bases 2 installed at each of the four corners of the lower surface of the platform 1; a conveyor belt 3 installed on the upper surface of the platform 1; a guide rail 4 installed on the upper surface of the platform 1; a slider 5 inserted inside the guide rail 4; a lifting slide rail 6 installed on the upper surface of the slider 5; a motor 7 installed on the upper surface of the lifting slide rail 6; a flywheel 8 rotatably connected to one side of the motor 7; a chain 9 rotatably connected to the surface of the flywheel 8; a guard plate 10 sleeved on the lower part of the chain 9; a top frame 11 inserted in the middle of the lifting slide rail 6; a lifting push rod 12 installed at one end of the lower surface of the top frame 11; and a lever installed on the upper surface of the top frame 11. 13. A pulley 14 is installed on the lower surface of the lifting push rod 12. An electric push rod 15 is installed on the lower surface of the top frame 11. An ultrasonic probe 16 is installed on the lower surface of the electric push rod 15. A scraper 17 is installed on the lower surface of the electric push rod 15. An extrusion device assembly 18 is installed on the lower surface of the electric push rod 15. A vertical arm 19 is installed on the upper surface of the platform 1. A central shaft 20 is installed in the middle of the arm 19. A scraper 21 is installed in the middle of the vertical arm 19. A collection box 22 is installed in the middle of the vertical arm 19. A retractor 23 is rotatably connected to the surface of the central shaft 20. The number of retractors 23 is ten.

[0030] Platform 1 serves as the supporting structure for this equipment. Four bases 2 are installed at the four corners of the lower surface of platform 1 to support the equipment. A conveyor belt 3 is installed on the upper surface of platform 1, allowing the metal structure to be placed within it and inspected at a uniform speed. A guide rail 4 is installed on the upper surface of platform 1, and a slider 5, after being inserted into the guide rail 4, can move parallel to the guide rail 4. A vertical lifting slide rail 6 is installed on the upper surface of the slider 5. An internal top frame 11 is inserted. To enable the top frame 11 to rise and fall at a uniform speed, a motor 7 is installed on the upper surface of the lifting slide rail 6. The motor 7 drives the flywheel 8 to rotate. The flywheel 8 is engaged with a chain 9. A guard plate 10 is installed on the lower part of one side of the lifting slide rail 6. A shaft supporting the chain 9 is installed inside the guard plate 10. The guard plate 10 can prevent foreign objects from entering. A lever 13 is installed on the upper surface of the top frame 11. The lever 13 is inserted into the chain 9. The lifting function can be realized by the forward and reverse square rotation of the flywheel.

[0031] By installing a lifting push rod 12 at one end of the lower surface of the top frame 11, and a pulley 14 on the lower surface of the lifting push rod 12, this design can prevent the top frame 11 from experiencing unexpected phenomena due to uneven gravity during lifting. The lifting push rod 12 can follow the lifting of the top frame 11, and its own damping characteristics can share the force of the top frame 11. It also moves in a parallel direction with the pulley group 14 following the top frame 11. Electric push rods 15 are installed on the lower surface of the top frame 11. There are a total of nine electric push rods 15. Each electric push rod 15 has a supporting platform installed at its lower part. An ultrasonic probe 16 is installed on the lower surface of this supporting platform. The ultrasonic probe 16 is the main detection device. An extrusion device assembly 18 is installed on the side of the lower surface of the supporting platform away from the ultrasonic probe 16. The extrusion device assembly 18 consists of a quantitative extrusion device and a coupling agent reservoir. The extrusion device assembly 19 extrudes an appropriate amount of coupling agent onto the surface of the sample brought by the conveyor belt 3, and then it is flattened by the scraper 17.

[0032] The central shaft 20 is supported by two vertical arms 19 on the upper surface of the mounting platform 1. The central shaft 20 has an inner and outer layer design. The inner part of the central shaft 20 is a rotatable arm, while the outer part, which is fitted onto the surface, is a fixed arm design. Multiple retractors 23 are mounted on the surface of the central shaft 20, with a total number of retractors 23. The retractor design consists of four rotating shafts and a conveyor belt. These four rotating shafts are divided into two large shafts and two small shafts. One large shaft is mounted on the central shaft 20, and the other large shaft is a drag shaft that rotates passively. One small shaft is installed at the farthest end of the conveyor belt 3, and the other small shaft is also a drag shaft, used to control the conveyor belt in the retractor 23 to prevent deviation. The retractor 23 is rotated counterclockwise by the central shaft 20 to retract the coupling agent remaining in the metal sample, ensuring the sample surface is clean. The retracted coupling agent will rotate with the retractor 23 until it reaches the scraper 21 installed in the middle of the vertical arm 19. The scraper 21 scrapes the coupling agent remaining in the retractor 23 into the collection box 22.
