Description

Technical Field

[0001] This application relates to the field of magnetic particle inspection of fillet welds, and more particularly to an auxiliary support device for magnetic particle inspection of fillet welds in mechanical equipment. Background Technology

[0002] Magnetic particle testing of fillet welds is a non-destructive testing method that uses the principle of magnetic flux leakage to attract magnetic particles. It is used to detect defects on the surface and near the surface of fillet welds in ferromagnetic materials. The core of the method is that after magnetizing the weld, a magnetic flux leakage is formed at the defect due to the difference in magnetic permeability. Magnetic particles accumulate at the defect location to form visible magnetic traces, thereby allowing for a direct judgment of the defect type and distribution.

[0003] Chinese Patent Publication No. CN214749962U discloses a single magnetic yoke device for inspecting small pipe joints and fillet welds. The device includes an insulation control switch, a lighting device, a magnetizing power supply, ferromagnetic material poles, a retractable ferromagnetic material, a handle, and a rotating fixing device. The ferromagnetic material poles contain an inner coil wound around them. However, existing devices have some shortcomings. Magnetic particle detectors are typically handheld by operators, but if the inspection position is long or the inspection time is long, the operator needs to hold the device for extended periods. Some integrated detectors are quite heavy, causing prolonged strain on the operator's wrists. Therefore, we propose a mechanical fillet weld magnetic particle inspection auxiliary support device to solve these problems. Utility Model Content

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] Please see Figure 1-4 In this utility model, an auxiliary support device for magnetic particle inspection of fillet welds in mechanical equipment includes a support frame 1. A pushing component 2 is installed inside the support frame 1, a sliding component 6 is installed on the outer surface of the pushing component 2, a lifting component 3 is installed on the bottom surface of the pushing component 2, a rotating component 4 is installed at the bottom end of the lifting component 3, and a detection component 5 is installed at the bottom end of the rotating component 4. Two support legs 9 are installed on the bottom surface of the support frame 1, a control component 7 is installed on the outer surface of one of the support legs 9, a base plate 11 is installed at the bottom end of both support legs 9, multiple moving wheels 23 are installed on the bottom surface of both base plates 11, and two side support rods 10 are installed on the outer surface of both support frames 1. Through the linkage of pushing, lifting, and rotating, the detection component 5 can be adjusted in multiple dimensions, replacing manual hand-held operation and solving the problem of wrist pain caused by long-term inspection.

[0017] The pushing component 2 includes a first electric push rod 13, which is located at the right end of the support frame 1. A moving block 12 is installed at the output end of the first electric push rod 13. The moving block 12 is a rectangular metal block with its upper surface in sliding contact with the inner wall of the top of the support frame 1 and its lower surface used to install the lifting component 3. It can move horizontally along the support frame 1 under the drive of the first electric push rod 13, thereby driving the detection component 5 to complete linear detection.

[0018] The sliding component 6 includes two sliding grooves 22 and two sliders 21. The two sliding grooves 22 are located on the inner wall of the support frame 1, and the two sliders 21 are located on the outer surface of the moving block 12. The two sliders 21 are adapted to the sliding grooves 22. The two sliding grooves 22 are "T"-shaped grooves, which are respectively opened on the inner wall of the top and bottom of the inner side of the support frame 1. The length of the sliding groove 22 is the same as that of the support frame 1. The inner wall is coated with wear-resistant grease to reduce sliding friction. The two sliders 21 are "T"-shaped metal blocks, which are symmetrically fixed to the top and bottom of the moving block 12 by welding. The size of the slider 21 is precisely adapted to the sliding groove 22, so that it can slide smoothly along the sliding groove 22 and prevent the moving block 12 from falling off the support frame 1. Together with the pushing component 2, it ensures that the trajectory of the detection component 5 is stable when it moves horizontally, and avoids the impact of deviation on the detection accuracy.

[0019] The lifting assembly 3 includes a support cylinder 14, which is located on the bottom surface of the moving block 12. A second electric push rod 15 is installed inside the support cylinder 14. A connecting rod 16 is installed at the output end of the second electric push rod 15. The connecting rod 16 is a solid metal rod with a diameter that matches the inner diameter of the support cylinder 14. It can be vertically lifted and lowered along the inner wall of the support cylinder 14. The bottom end is used to install a rotating assembly 4 to transmit the power of the second electric push rod 15 to the detection assembly 5.

[0020] The rotating assembly 4 includes a rotary joint 20, which is located at the bottom end of the connecting rod 16. One end of the rotary joint 20 is equipped with a mounting plate 19. The rotary joint 20 is a rotating structure, and its top end is fixed to the bottom end of the connecting rod 16 by threads. It has good load-bearing capacity and has a wire channel inside for the wiring connection of the detection assembly 5. The mounting plate 19 is a rectangular metal plate with multiple bolt holes on its surface, which can be adapted to the installation of different models of detection assemblies 5. The operator can adjust the angle of the mounting plate 19 by rotating the rotary joint 20 to ensure that the contact foot 18 of the detection assembly 5 is completely in contact with the fillet weld surface.

[0021] The inspection component 5 includes a flaw detector body 17, which is located on the outer surface of the mounting plate 19. Two contact feet 18 are installed on the bottom surface of the flaw detector body 17. The flaw detector body 17 is a magnetic particle flaw detector for fillet welds, which has a magnetization intensity adjustment function and can adjust the magnetization current according to the weld thickness. It is fixed to the outer surface of the mounting plate 19 by bolts. The contact feet 18 are made of copper alloy with nickel plating, which has good conductivity and wear resistance. The distance between the two contact feet 18 can be finely adjusted by adjusting bolts to ensure precise contact with the weld toes on both sides of the fillet weld, so as to achieve effective magnetization of the weld and then judge defects by magnetic particle accumulation.

[0022] The control component 7 includes a control panel 8, which is located on the outer surface of one of the support legs 9. The control panel 8 is electrically connected to the device via wires. The control panel 8 has a built-in PLC controller and is electrically connected to the first electric push rod 13, the second electric push rod 15, and the flaw detector body 17 via wires.

[0023] The working principle of this application is: When using this mechanical equipment's magnetic particle inspection auxiliary support device for fillet welds, the device is first pushed to the inspection position and fixed by the moving wheels 23. Then, the lifting component 3 is activated through the control panel 8 of the control component 7. The second electric push rod 15 drives the connecting rod 16 to lift the inspection component 5, so that the contact foot 18 is adapted to the height of the fillet weld. At the same time, the rotary joint 20 of the rotating component 4 is rotated to make the contact foot 18 fit the weld surface and lock the angle. Then, after setting the magnetization current of the flaw detector body 17, the pushing component 2 is activated, so that the first electric push rod 13 drives the moving block 12 to move along the slide 22 and drive the inspection component 5 to perform linear inspection along the weld. During the inspection, the leakage magnetic field formed at the weld defect attracts magnetic powder. The operator observes the magnetic trace to judge the defect. Finally, after the inspection is completed, all components are reset and the device moves to the next position. The whole process does not require manual handling of the flaw detector, reducing labor intensity, and multi-dimensional adjustment ensures inspection accuracy.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
