[0023] Specifically, the cleaning component 2 includes a connecting structure 21, a cleaning sleeve 22, a cleaning ring 23, and a cleaning brush 25. The mounting cylinder 4 has cleaning sleeves 22 on both sides, and a connecting structure 21 connects the cleaning sleeves 22 to the mounting cylinder 4. The cleaning sleeves 22 have cleaning rings 23 inside, and the cleaning rings 23 have cleaning brushes 25 on their surfaces.

[0024] By adopting the above technical solution, the connecting structure 21 connects the installation cylinder 4 and the cleaning sleeve 22. The cleaning soft brush 25 on the surface of the cleaning ring 23 can clean the dust on the surface of the wire rope 1, so that the surface of the wire rope 1 entering the installation cylinder 4 for testing is clean and the test results are better.

[0025] Specifically, the connecting structure 21 includes a connecting plate 211, a connecting bracket 212, and fixing screws 213. The connecting bracket 212 is provided between the mounting cylinder 4 and the cleaning sleeve 22. The connecting plate 211 is located at the lower end of the connecting bracket 212, and the fixing screws 213 are located inside the connecting plate 211.

[0026] By adopting the above technical solution, the connecting plate 211 is fixed by the fixing screw 213, so that the connecting frame 212 can connect the cleaning sleeve 22 and the mounting cylinder 4.

[0027] Specifically, the cleaning assembly 2 also includes a telescopic link 24 and a connecting spring 26. The telescopic link 24 is located between the cleaning sleeve 22 and the cleaning ring 23, and the connecting spring 26 is located inside the telescopic link 24.

[0028] By adopting the above technical solution, the connecting spring 26 enables the telescopic link 24 to have elastic telescopic capability, so that the cleaning soft brush 25 can be used with steel wire ropes 1 of different specifications.

[0029] In this embodiment, the mounting cylinder 4 is fixed to the tower crane boom by the mounting rod 5. The wire rope 1 passes through the mounting cylinder 4, and the guide wheel 8 in the side plate 7 limits its movement. When the wire rope 1 moves, the magnetization mechanism 3 and the detection mechanism 9 cooperate to easily perform magnetic leakage flaw detection on the wire rope 1. The connecting plate 211 is fixed by the fixing screw 213, so that the connecting frame 212 can connect the cleaning sleeve 22 and the mounting cylinder 4. Thus, the connecting structure 21 can simultaneously install the cleaning sleeve 22 when the mounting cylinder 4 is installed. The cleaning soft brush 25 on the surface of the cleaning ring 23 can clean the dust on the surface of the wire rope 1, making the surface of the wire rope 1 that enters the mounting cylinder 4 for testing clean and the test results better. The connecting spring 26 gives the telescopic connecting rod 24 elastic extension and retraction capability, so that the cleaning soft brush 25 can be used for wire ropes 1 of different specifications.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the adjusting component 6 includes an adjusting frame 61, a rotating shaft 62, a disc 63, and a fixed gear 66. The adjusting frame 61 is provided on the side surface of the mounting cylinder 4. The rotating shaft 62 is provided inside the adjusting frame 61 and extends through the side plate 7. One end of the rotating shaft 62 is provided with the disc 63, and the other end of the rotating shaft 62, located inside the mounting cylinder 4, is provided with the fixed gear 66.

[0032] By adopting the above technical solution, rotating the disc 63 causes the rotating shaft 62 inside the adjusting frame 61 to drive the side plate 7 to rotate, thereby making it easy to adjust the angle position of the guide wheel 8 so that it can limit the steel wire rope 1 of different specifications. The fixed gear 66 meshes with one end of the rotating shaft 62 to fix the rotating shaft 62.

[0033] Specifically, the adjustment component 6 also includes a pointer 64 and a dial 65. The dial 65 is provided on one side surface of the adjustment frame 61, and the pointer 64 is provided on the surface of the rotating shaft 62 at a position corresponding to the dial 65.

[0034] By adopting the above technical solution, the rotating shaft 62 drives the pointer 64 to rotate synchronously. By observing the scale indicated by the pointer 64 on the surface of the dial 65, multiple sets of guide wheels 8 can be easily adjusted to the same tilt angle.

[0035] In this embodiment, rotating the disc 63 causes the rotating shaft 62 inside the adjusting frame 61 to rotate the side plate 7, thereby facilitating the adjustment of the angle position of the guide wheel 8. This allows for the limiting of different specifications of wire rope 1. The fixed gear 66 meshes with one end of the rotating shaft 62, which can fix the rotating shaft 62. The rotating shaft 62 drives the pointer 64 to rotate synchronously. By observing the scale indicated by the pointer 64 on the surface of the dial 65, multiple sets of guide wheels 8 can be easily adjusted to the same tilt angle.

[0036] The structure and working principle of the magnetization mechanism 3 and the detection mechanism 9 in this utility model have been disclosed in the wire rope leakage magnetic field detection device disclosed in Chinese patent application No. 202320893896.5. The working principle of the magnetization mechanism 3 is that after the excitation coil is energized with current, it generates an excitation magnetic field for magnetizing the wire rope 1. The temperature detection element detects the ambient temperature and sends the temperature data to the data processing platform. The data processing platform adjusts the current of the excitation coil to counteract the influence of the ambient temperature on the magnetization magnetic field strength of the wire rope 1. The working principle of the detection mechanism 9 is that the detection element is a Hall element, which is used to detect the leakage magnetic field on the surface of the wire rope 1 after it has been magnetized by the excitation coil due to wire breakage, wear, or other damage. The Hall element generates the Hall effect, which can sense the spatial magnetic field under static conditions and convert the magnetic field signal into a voltage signal, and send it to the data processing platform for processing.

[0037] The working principle and usage process of this utility model are as follows: When using this utility model, the mounting cylinder 4 is fixed to the tower crane boom via the mounting rod 5. The wire rope 1 passes through the mounting cylinder 4, and the guide wheel 8 inside the side plate 7 limits its movement. When the wire rope 1 moves, the magnetization mechanism 3 and the detection mechanism 9 cooperate to easily perform magnetic leakage testing on the wire rope 1. The connecting plate 211 is fixed by the fixing screw 213, allowing the connecting frame 212 to connect the cleaning sleeve 22 to the mounting cylinder 4. This allows the connecting structure 21 to simultaneously install the cleaning sleeve 22 while the mounting cylinder 4 is being installed. The cleaning brush 25 on the surface of the cleaning ring 23 can clean the dust on the surface of the wire rope 1, allowing it to move smoothly. The surface of the steel wire rope 1 tested in the installation cylinder 4 is clean, resulting in better test results. The connecting spring 26 enables the telescopic link 24 to have elastic extension and retraction capabilities, allowing the cleaning brush 25 to be used with steel wire ropes 1 of different specifications. Rotating the disc 63 causes the rotating shaft 62 in the adjusting frame 61 to drive the side plate 7 to rotate, thereby facilitating the adjustment of the angle position of the guide wheel 8, which can limit the movement of steel wire ropes 1 of different specifications. The fixed gear 66 meshes with one end of the rotating shaft 62, which can fix the rotating shaft 62. The rotating shaft 62 drives the pointer 64 to rotate synchronously. By observing the scale indicated by the pointer 64 on the surface of the dial 65, multiple sets of guide wheels 8 can be easily adjusted to the same tilt angle.
