The moving end of the guiding unit is connected to a mounting frame 8, on which a defect scanning probe 9 is mounted to scan the cable surface. A closed-loop transmission mechanism drives the detection probe mounting frame 8 to move back and forth along the circumferential direction of the cable, forming a detection path covering multiple cable surfaces. The support base 1 is made of metal, such as cast iron or stainless steel, and is manufactured through casting or welding. The horizontal working platform 2 is made of the same metal as the support base 1 and is fixed to the support base 1 by welding or bolting. The horizontal working platform 2 provides a mounting support platform for components such as the detection chamber 3. The detection chamber 3 is made of metal, such as aluminum alloy, and is fixed to the horizontal working platform 2 by welding or bolting. The support base 5 is made of metal, such as stainless steel, and is fixed to the outer wall of the detection chamber 3 by welding or bolting. Adjacent support bases are not on the same horizontal plane. The support base 5 provides an installation support platform for the support plate 6, which is made of metal, such as aluminum alloy, and is connected to the support base 5 by welding. The support plate 6 provides installation support for the cable positioning roller 7. The cable positioning roller 7 is made of rubber or plastic with a smooth surface to reduce wear on the cable surface. The function of the cable positioning roller 7 is to guide the cable to pass accurately and smoothly into the detection chamber 3, preventing the cable from deviating or shaking during passage, and ensuring the accuracy of the detection. The guide unit is linked with the closed-loop transmission mechanism. When the closed-loop transmission mechanism drives the mounting frame 8 to move... When in motion, it provides guidance for the movement of the mounting frame 8, which provides a mounting support platform for the defect scanning probe 9. The defect scanning probe 9 uses sensors such as laser scanning probes or cameras, such as LJ-V series laser scanning probes or industrial cameras. The defect scanning probe 9 scans the cable surface by emitting lasers or receiving light, acquires image information of the cable surface, and transmits it to the control system for analysis and processing, thereby detecting defects on the cable surface, such as scratches, pits, and protrusions.

The output shaft of the drive motor 10 is connected to an active shaft 11 extending into the inner cavity of the detection cavity 3. A bearing seat 12 is disposed on the inner wall of the detection cavity 3. A driven shaft 13 is rotatably connected inside the bearing seat 12. A linkage structure is provided between the active shaft 11 and the driven shaft 13. The drive motor 10 is an AC servo motor, which provides the power source for the entire closed-loop transmission mechanism. The active shaft 11 is a steel shaft, which transmits the power of the drive motor 10 to the linkage structure. The bearing seat 12 is made of metal, such as copper alloy, and has bearings installed inside. The bearing seat 12 provides rotational support for the driven shaft 13, ensuring that the driven shaft 13 can rotate smoothly and steadily.

[0025] Please see Figure 3 A further embodiment of this solution is as follows: The linkage structure includes a drive sprocket 14 disposed on the outer wall of the drive shaft 11, and a driven sprocket 15 disposed on the outer wall of the driven shaft 13. The drive sprocket 14 and the driven sprocket 15 are meshed and connected to a chain 16. The drive sprocket 14 is made of metal, such as steel, and is fixed to the drive shaft 11 by a key connection or interference fit. The drive sprocket 14 rotates under the drive of the drive shaft 11, transmitting power to the chain 16. The driven sprocket 15 is made of the same metal as the drive sprocket 14 and is fixed to the driven shaft 13 by a key connection or interference fit. When the drive sprocket 14 rotates, the chain 16 drives the driven sprocket 15 to rotate, thereby realizing the linkage between the drive shaft 11 and the driven shaft 13.

[0026] Please see Figure 3 A further solution based on this embodiment is as follows: The guiding unit includes an annular guide rail 17 disposed on the inner wall of the detection cavity 3. At least two sliders 18 are slidably connected to the annular guide rail 17. Each slider 18 has a receiving block 19 fixedly connected to the connecting surface of the slider 18 and connected to the chain 16. The surface of the receiving block 19 is connected to the mounting bracket 8. The annular guide rail 17 is made of metal, such as stainless steel, and is fixed to the inner wall of the detection cavity 3 by bolts or welding. The annular guide rail 17 provides a sliding track for the sliders 18, ensuring that the sliders 18 can move along the annular trajectory, thereby... The mounting bracket 8 is able to reciprocate along the circumferential direction of the cable. The slider 18 is made of metal or plastic and has rolling elements installed inside to reduce friction with the annular guide rail 17. The receiving block 19 is made of metal, such as aluminum alloy, and is fixed to the slider 18 by welding or bolting. The receiving block 19 is connected to the chain 16 on one hand to transmit the power of the chain 16 to the slider 18, and on the other hand, its surface is connected to the mounting bracket 8 to provide a mounting support platform for the mounting bracket 8, ensuring that the mounting bracket 8 can move stably with the slider 18.

[0027] Please see Figure 2 A further solution based on this embodiment is as follows: the inner wall of the detection cavity 3 is also provided with a supplementary lighting unit. The supplementary lighting unit is composed of multiple LED light source blocks 20 with built-in power supplies distributed at intervals. The LED light source blocks have the advantages of high luminous efficiency, long life and low heat generation. The built-in power supply provides power support for the LED light source blocks so that they can emit light continuously. The function of the supplementary lighting unit is to provide sufficient and uniform illumination to the surface of the cable during the detection process, improve the clarity and accuracy of the image information obtained by the defect scanning probe 9, and reduce the detection error caused by insufficient light or uneven illumination.

[0028] Please see Figure 5 A further embodiment of this solution is as follows: the upper end of the detection cavity 3 is detachably connected to a maintenance cover 21, and the lower end face of the maintenance cover 21 is integrally fixed with a protrusion 22. The upper end face of the detection cavity 3 is provided with a recess 23 that matches the protrusion 22. The protrusion 22 is inserted into the recess 23. The maintenance cover 21 is made of metal, such as aluminum alloy. The function of the maintenance cover 21 is to facilitate the inspection and maintenance of the components inside the detection cavity 3. When maintenance is required, the maintenance cover 21 can be opened to inspect and repair components such as the closed-loop transmission mechanism, the guide unit, and the defect scanning probe 9. The protrusion 22 is made of the same metal as the maintenance cover 21 and is connected to the maintenance cover 21 by casting or machining. When the maintenance cover 21 is closed, the protrusion 22 is inserted into the recess 23 to provide a sealing effect.

[0029] Please see Figure 5 A further solution based on this embodiment is as follows: a permanent magnet is provided on the contact surface between the protrusion 22 and the cavity 23, and the contact surface between the protrusion 22 and the cavity 23 is magnetically connected. The permanent magnet is made of a strong magnetic material such as neodymium iron boron and is fixed on the contact surface between the protrusion 22 and the cavity 23 by embedding or pasting. The magnetic connection method allows the protrusion 22 to be easily inserted into the cavity 23 and fixed by magnetic adsorption, ensuring the connection stability between the inspection cover 21 and the detection cavity 3, and also facilitating the disassembly and installation of the inspection cover 21.

[0030] Working principle: The cable passes through the cable passage channels 4 at both ends of the detection cavity 3 and smoothly enters the detection cavity 3 under the guidance of the cable positioning rollers 7 of the guide mechanism, reducing wear on the cable surface and preventing deviation. The drive motor 10 is started, and the power is transmitted to the driven shaft 13 through the drive shaft 11, drive sprocket 14, chain 16, and driven sprocket 15. Through the linkage structure, the mounting frame 8 is driven to move circumferentially along the slider 18 on the annular guide rail 17 to form a detection path covering the surface of the cable. The LED light source block 20 of the supplementary light unit provides uniform illumination to the detection area and improves image clarity. During the movement, the defect scanning probe 9 (such as a laser scanning probe or industrial camera) on the mounting frame 8 continuously scans the surface of the cable, acquires image information and transmits it to the control system for analysis and processing, and detects defects such as scratches and dents in real time. After the detection is completed, the cable passes out from the other side channel.

[0031] If maintenance is required, the inspection cover 21 can be removed, and the cavity can be quickly opened by the separation structure of the protrusion 22 and the concave cavity 23 attracted by the permanent magnet, so as to inspect and maintain the closed-loop transmission mechanism, guide unit and other components.
