DETAILED DESCRIPTION

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of this utility model.

[0027] Example 1

[0028] like Figures 1-3 As shown, this embodiment discloses a magnetic particle inspection trolley, including a frame body 1 and a control terminal 2 and an electrical control box 3 connected to each other on the frame body 1. It also includes a magnetization mechanism 4 mounted on the frame body 1. The magnetization mechanism 4 includes a handheld bracket 41, an operation module 42, a magnetic yoke assembly 43 and a flaw detection assembly 44 electrically connected to the operation module 42. The magnetic yoke assembly 43 and the flaw detection assembly 44 are connected to the control terminal 2 through the operation module 42. The operation module 42 is used to control the opening or closing of the magnetic yoke assembly 43 and the flaw detection assembly 44 to take pictures or record videos of the workpiece under test.

[0029] like Figure 1 As shown, the main frame 1 serves as the supporting structure for the entire device and is made of robust and durable materials to ensure stability and reliability during operation. Wheels are mounted beneath the main frame 1, with the rear wheels coaxially mounted to enable stable movement of the main frame 1. The front wheels are omnidirectional wheels, allowing for steering control of the main frame 1. A control terminal 2 is mounted atop the main frame 1. This control terminal 2 is an industrial computer, whose high-performance processor, large-capacity memory, and high-speed storage devices work together to provide robust hardware support for running the specially developed magnetic particle inspection control software. This software communicates with the vehicle's operation module 42 via a network protocol or dedicated interface, enabling centralized control and data transmission management of the entire inspection process.

[0030] The electrical control box 3 is located below the main frame 1 and is existing technology. The power module inside the electrical control box 3 is connected via dense wiring to the circuit protection device, voltage regulation module, and other electrical components on the main frame 1 (such as the control terminal 2 and magnetizing mechanism 4). The fuses and circuit breakers in the circuit protection device are connected in series to the circuit. In the event of an overload or short circuit, the circuit can be quickly cut off to ensure the safety of the equipment and operators. The voltage regulation module, through complex circuits and electronic components, converts the input power voltage into a stable, specific voltage suitable for the operation of different components, and precisely supplies power to each component through multiple branch lines.

[0031] The magnetization mechanism 4 is mounted on the frame body 1 and includes a handheld bracket 41. The handheld bracket 41 is connected to the frame body 1 via a connector, allowing it to be easily removed for handheld operation and securely mounted on the frame when not in use.

[0032] Among them, such as Figures 2-3 As shown, an operation module 42 is mounted on the handheld bracket 41, and the operation module 42 includes a mounting housing 421. A control board is housed inside the mounting housing 421, and the control board is electrically connected to the control terminal 2 via a connecting cable to realize the transmission of data and commands. The magnetic yoke assembly 43 and the flaw detection assembly 44 are mounted on the mounting housing 421 and are electrically connected to the control terminal 2 via the control board through a connecting cable.

[0033] The magnetic yoke assembly 43 includes an iron core 431 mounted on a handheld support 41. A magnetizing coil 432 is wound around the iron core 431 and electrically connected to the control box 3 via a connecting wire. The iron core 431 is made of a high-permeability material, effectively concentrating the magnetic field. When the power is turned on, current flows through the magnetizing coil 432, generating a magnetic field that magnetizes the iron core 431, thereby magnetizing the workpiece being tested.

[0034] The flaw detection component 44 includes a camera 441 mounted on a handheld bracket 41 and connected to the operation module 42, and a lighting module 442. The flaw detection component 44 is located below the mounting housing 421. The camera 441 is a high-definition digital camera capable of taking photos and recording videos. A lighting module 442, connected to the operation module 42, is located around the camera 441. This module includes high-brightness LED lights 4421 and ultraviolet fluorescent lights 4422 located on either side of the camera 441. Both are connected to a switch 424 on the mounting housing 421 via a control board. Operators can switch between the LED lights 4421 and the fluorescent lights 4422 according to the working environment using the switch 424. The LED lights 4421 provide normal illumination, while the ultraviolet fluorescent lights 4422 are used to develop fluorescent magnetic powder, facilitating observation of magnetic traces in special environments.

[0035] By integrating the flaw detection assembly 44 and the magnetic yoke assembly 43 onto the handheld bracket 41, seamless integration of magnetization and flaw detection operations is achieved, greatly simplifying the operation process. Operators no longer need to frequently switch between different devices, reducing operation steps and time, and significantly improving work efficiency. At the same time, this integrated design reduces the possibility of operational errors and improves the accuracy and reliability of inspection.

[0036] like Figures 2-3As shown, the operation module 42 includes a mounting housing 421 mounted on a handheld bracket 41. Inside the mounting housing 421 is a control board electrically connected to the control terminal 2 via a connecting cable. The control board is electrically connected to a camera 441, a light module 442, and a magnetizing coil. The mounting housing 421 also has a switching button 422 connected to the camera 441 via the control board and a switch button 423 connected to the magnetic yoke assembly 43. The switching button 422 is used to control the camera 441 to take pictures or record videos.

[0037] The mounting housing 421 has a switching button 422 and a power switch 423. The switching button 422 is connected to the camera 441 via a control board and is used to control the camera 441 to take pictures or record videos. The power switch 423 is connected to the magnetic yoke assembly 43 and is used to control the opening or closing of the magnetic yoke assembly 43. In addition, the mounting housing 421 is also equipped with a recording indicator light 425 connected to the control board. When the camera 441 is in recording mode, the recording indicator light 425 lights up to indicate that the camera 441 is in recording mode. When the camera 441 is recording, the user can use the recording indicator light 425 to determine the current mode of the camera 441.

[0038] With the above structure, when using this magnetic particle inspection carriage, the operator first pushes the carriage near the workpiece to be inspected. Holding the handheld bracket 41, the operator brings the magnetic yoke assembly 43 close to the workpiece and presses the switch button 423 to start magnetization. Simultaneously with magnetization, a suitable light is turned on via the selector switch 424. Then, after magnetization is complete, a magnetic powder suspension is sprayed onto the magnetized area, allowing the magnetic powder to form magnetic traces on the workpiece surface. The magnetized workpiece surface is then observed using the camera 441. If recording is required, the operator controls whether to take a photo or record video via the switch button 422.

[0039] In summary, integrating the flaw detection component 44 and the magnetic yoke component 43 onto the handheld bracket 41 and achieving unified control through the operation module 42 greatly simplifies the operation process and improves work efficiency. The integrated design allows magnetization and flaw detection operations to be performed seamlessly, eliminating the need for frequent equipment switching. The various buttons and switches on the operation module 42 facilitate direct control of each component by the operator, reducing reliance on and frequent operation of the control terminal 2, allowing the operator to focus more on flaw detection work.

[0040] Example 2

[0041] like Figures 4-6 As shown, based on Embodiment 1, since both the flaw detection component 44 and the magnetic yoke component 43 are integrated on the handheld bracket 41, when the operator sprays the magnetic powder suspension during daily use, the magnetic powder suspension will adhere to the lens of the camera 441, causing the camera 441 to become blurry. Therefore, this embodiment adds a protective structure for the lens of the camera 441 based on Embodiment 1.

[0042] The lens of the camera 441 is covered with a transparent, hemispherical lens cover 5. A drive ring 6 is rotatably connected to the lens cover 5. A scraper 7 that fits against the surface of the lens cover 5 is provided on the drive ring 6. A small motor 8 is also provided on the mounting housing 421. The output shaft of the small motor 8 is geared to the drive ring 6. A dirt guide groove 9 is provided on the edge of the scraper 7 that fits against the lens cover 5. The depth of the dirt guide groove 9 gradually increases from the side close to the scraper 7 that contacts the lens cover 5 to the outside.

[0043] The transparent hemispherical lens cover 5 forms a protective barrier around the lens of the camera 441, preventing suspended liquids or dirt from directly contacting the lens and causing damage.

[0044] During daily use, when the operator notices a blurry image or after spraying a suspension, they can control the small motor 8 to rotate one revolution via a touch switch on the mounting housing 421. The output shaft of the small motor 8 rotates, driving the drive ring 6 to rotate around the lens cover 5 via gear meshing. As the drive ring 6 rotates, the scraper 7 on the drive ring 6, which is in contact with the surface of the lens cover 5, scrapes away dirt from the surface of the lens cover 5, effectively and promptly removing dirt and ensuring clear images captured by the camera 441, without affecting the normal operation of the flaw detection work.

[0045] like Figure 6 As shown, the dirt-guiding groove 9 on the edge of the scraper 7 gradually deepens from the side closest to the contact point between the scraper 7 and the lens cover 5 outwards, forming a channel to guide dirt outwards. This design allows dirt to flow smoothly outwards along the dirt-guiding groove 9 when the scraper 7 removes dirt, preventing it from accumulating or re-adhering to the surface of the lens cover 5. This achieves a good cleaning effect, maintains the transparency and cleanliness of the lens cover 5, and ensures the normal operation and image quality of the camera 441. For dirt on the scraper 7, the user can wipe it with a cloth for easy reuse.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
