[0002] A cable is a multi-strand rope, mainly used for tying ships or other floating structures, and for various lifting, towing and fixing operations. It is usually made of high-strength, wear-resistant materials, such as fibers, synthetic fibers or wire ropes. The cable has tensile resistance, impact resistance, wear resistance, flexibility and softness, and can withstand huge tension and friction. After long-term use, the cable is prone to quality problems such as aging and breakage of the insulation surface due to wear and other reasons, so safety inspections are required.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5As shown, a cable surface defect detection device described in an embodiment of the present invention includes a conveying component and a detection component. The conveying component includes a winding roller 1 and a driving motor 2. The output end of the driving motor 2 is fixedly connected to one end of the winding roller 1. The conveying component drives the winding roller 1 to rotate through the driving motor 2. When the winding roller 1 rotates, the cable is wound to realize the conveying of the cable. The detection component includes a gear ring 3, a gear 4, a transmission component, a rotating positioning plate 5 and a plurality of detectors 6. The gear ring 3 is fixedly installed on the outer wall of the winding roller 1. The teeth of the gear ring 3 are meshed with the teeth of the gear 4. The transmission component and the rotating positioning plate 5 are both located on one side of the winding roller 1. The plurality of detectors 6 are all located on the inner side of the rotating positioning plate 5. The detection component drives the rotating positioning plate 5 to rotate through the gear ring 3, the gear 4 and the transmission component. When the rotating positioning plate 5 rotates, the detector 6 rotates around the cable for detection. When performing the detection, one end of the cable to be detected is fixed on the winding roller 1, and then the detection is started. The driving motor 2 is driven, and the driving motor 2 drives the winding roller 1 to rotate to wind up the cable, thereby driving the cable to move. When the winding roller 1 rotates to wind up the cable, the winding roller 1 will drive the gear ring 3 to rotate. When the gear ring 3 rotates, it will drive the gear 4 meshing with it to follow the rotation. When the gear 4 rotates, it will drive the rotating positioning plate 5 to rotate through the transmission component. When the rotating positioning plate 5 rotates, it will drive the detector 6 on the inside to rotate. The cable is detected while the detector 6 rotates. Since there are multiple detectors 6 and they are arranged continuously, when a point of the cable reaches the first detector 6, the detection begins. As the detector 6 rotates, when the point reaches the last detector 6, the detector 6 rotates one circle, so that each position of the cable will pass through the detection area of ​​the detector 6, so that the cable is fully detected, and there is no need to detect the cable multiple times. The detection is convenient and comprehensive, which improves the detection efficiency while ensuring the detection effect of the device.

[0024] like Figures 1 to 5 As shown, the transmission assembly includes a rotating shaft 7 and a transmission wheel 8, the outer wall of the rotating shaft 7 is fixedly connected to the inner wall of the gear 4, the transmission wheel 8 is fixedly installed on the outer wall of the rotating shaft 7, a positioning seat 9 is provided on one side of the winding roller 1, a rotating ring 10 is rotatably installed on the inner wall of the positioning seat 9, a rotating positioning plate 5 is fixedly installed on the outer wall of the rotating ring 10, a driven wheel 11 is fixedly installed on the outer wall of the rotating ring 10, and a transmission belt 12 is transmission-connected between the driven wheel 11 and the outer wall of the transmission wheel 8; when detecting, the gear 4 rotates with the winding roller 1 under the action of the gear ring 3, the rotating shaft 7 is driven to rotate when the gear 4 rotates, the rotating shaft 7 is driven to rotate when the rotating shaft 7 is rotated, the transmission wheel 8 is driven to rotate when the transmission wheel 8 is rotated, the driven wheel 11 is driven to rotate through the transmission belt 12, the driven wheel 11 is driven to rotate when it rotates, and then the rotating positioning plate 5 is driven to rotate, the detector 6 is rotated around the cable by the rotation of the rotating positioning plate 5, the cable is detected while the detector 6 is rotating, so as to achieve the effect of comprehensive detection of the cable.

[0025] like Figures 5 to 7 As shown, a support ring 13 is fixedly installed on the outer wall of one end of the rotating positioning plate 5 away from the rotating ring 10, and an extrusion assembly is arranged below the support ring 13. A plurality of rotating seats 14 are fixedly installed on the inner walls of the support ring 13 and the rotating ring 10. A rotating plate 15 is rotatably installed on the inner wall of the rotating seat 14. A ball bearing 16 is fixedly installed on the outer wall of the rotating plate 15 away from the rotating seat 14. An arc-shaped telescopic rod 17 and an arc-shaped elastic member 18 are fixedly installed between the support ring 13 and the rotating ring 10 and the rotating plate 15 on the inner side thereof, respectively. The arc-shaped elastic member 18 is sleeved on the outer side of the arc-shaped telescopic rod 17. When testing, the cable will pass between the ball bearings 16 on the inner side of the rotating ring 10 and the support ring 13. The rotating plates 15 on the same side are a group. In the initial state, the two groups of rotating plates 15 will be in an expanded state under the action of the elastic force of the arc-shaped elastic member 18. At this time, the ball bearings 16 on the same side are separated from each other, so that When the cable passes through, after one end of the cable is passed through the ball bearing 16 and fixed on the winding roller 1, the rotating plate 15 is squeezed by adjusting the squeezing assembly. After the rotating plate 15 is squeezed, the arc-shaped elastic member 18 will shrink, so that the two groups of rotating plates 15 gather together. When the rotating plates 15 gather together, the ball bearings 16 on the same side will approach each other. The ball bearings 16 that are close will squeeze the cable, thereby fixing the position of the cable, so that a section of the cable below the detector 6 is in a horizontal state, thereby keeping it parallel to the detector 6. The position of the cable is fixed by the ball bearing 16 to prevent the cable from shifting during movement, thereby ensuring the detection effect of the device on the cable. The cable is fixed by the ball bearing 16. The ball bearing 16 can ensure that the cable can move under the action of the winding roller 1 while preventing the cable from rotating with the rotating ring 10, thereby ensuring the effectiveness of comprehensive detection.

[0026] like Figures 5 to 8As shown, the extrusion assembly includes a rotating adjustment plate 19, which is fixedly installed between the support ring 13 and the outer wall of the rotating ring 10 away from the rotating positioning plate 5. A slide plate 20 is symmetrically slidably installed on the inner wall of the rotating adjustment plate 19. A support plate 21 is fixedly installed on the top of the slide plate 20. A positioning ring 22 is fixedly installed on the top inner wall of the support plate 21. The two positioning rings 22 are respectively in conflict with the corresponding rotating plates 15. A support 23 is symmetrically fixedly installed on the bottom of the rotating adjustment plate 19. A bidirectional threaded rod 24 is rotatably installed between the inner walls of the two supports 23. The inner walls of the two slide plates 20 are threadedly connected to the outer walls of the bidirectional threaded rod 24. The bidirectional threaded rod 24 is threadedly connected to the inner walls of the two slide plates 20. A handle 25 is fixedly installed on the outer wall of the threaded rod 24; when the position of the cable is fixed, the bidirectional threaded rod 24 is driven to rotate by rotating the handle 25, and when the bidirectional threaded rod 24 rotates, it will drive the two slides 20 to move synchronously to both sides, and when the slide 20 moves, it will drive the positioning ring 22 to move through the support plate 21, and when the positioning ring 22 moves to both sides, it will squeeze the rotating plates 15 on both sides, so that the ball bearings 16 on both sides gather together to position the cable, thereby achieving the effect of fixing the cable, and under the action of the bidirectional threaded rod 24, the distance between the ball bearings 16 can be adjusted, so that the device is suitable for cables of different diameters.

During measurement, the rotating shaft 7 will drive the driving wheel 26 to rotate. When the driving wheel 26 rotates, the driving shaft 27 will drive the driving block 28 to rotate. When the driving block 28 rotates, it will drive the hinge 30 to swing back and forth through the driving rod 29. When the hinge 30 swings, it will drive the cleaning brush 33 to swing through the vertical plate 31 and the horizontal plate 32. The cable will pass between the two cleaning brushes 33 during the transportation process. When the cleaning brush 33 swings, it will clean the surface of the cable to remove dirt and impurities on the surface of the cable, so as to prevent obstructions such as dirt and impurities from covering up the defects on the surface of the cable, thereby improving the detection accuracy of the device.

[0028] like Figures 9 and 10As shown, a slide seat 34 is provided below the lower transverse plate 32, and a slider is fixedly installed on the bottom of the lower transverse plate 32, and the outer wall of the slider is slidably connected to the inner wall of the slide seat 34; through the cooperation of the slide seat 34 and the slider, the transverse plate 32 is limited to ensure that the transverse plate 32 can move along the preset direction, thereby ensuring the effectiveness of the cable cleaning work.

[0029] like Figures 9 and 10 As shown, an extension block 35 is fixedly installed on one side of the cross plate 32, and elastic stop blocks 36 are symmetrically fixedly installed on the adjacent outer walls of the two extension blocks 35, and the elastic stop blocks 36 are staggered with each other; when cleaning the cable, the reciprocating swing of the cross plate 32 will drive the extension block 35 to swing, and the swing of the extension block 35 will drive the elastic stop block 36 to swing, and the elastic stop block 36 will come into conflict with the cable when swinging. When the elastic stop block 36 passes over the cable due to deformation, the cable will shake due to a certain tension. The shaking of the cable can speed up the frequency of contact between the cable and the cleaning brush 33, so that the cleaning brush 33 can better clean the cable. At the same time, the impurities on the surface of the cable can be shaken off when the cable shakes, so that the detection effect of subsequent detection work is better.

[0030] like Figures 3 to 5 and Fig.11 As shown, a mounting plate 37 is slidably installed on the inner wall of the rotating positioning plate 5, and the detector 6 is fixedly installed on the inner wall of the mounting plate 37. An adjusting frame 38 is fixedly installed on the top of the rotating positioning plate 5. A one-way threaded rod 39 is threadedly installed on the inner wall of the adjusting frame 38. One end of the one-way threaded rod 39 is rotatably connected to the inner wall of the mounting plate 37, and an adjusting knob 40 is fixedly installed on the other end of the one-way threaded rod 39; the one-way threaded rod 39 is driven to rotate by rotating the adjusting knob 40, and the one-way threaded rod 39 will drive the mounting plate 37 to move when the one-way threaded rod 39 rotates, and the mounting plate 37 will drive the detector 6 to move when it moves, thereby achieving the effect of adjusting the distance between the detector 6 and the cable. The device can adjust the distance between the detector 6 and the cable according to cables of different diameters to ensure that the cable is detected at an appropriate distance, thereby ensuring the detection effect of the device.

[0031] like Figures 1 to 3 As shown, roller seats 41 are provided on both sides of the rotating positioning plate 5, the inner wall of the roller seat 41 close to the positioning seat 9 is rotatably connected to the outer wall of the winding roller 1, the outer wall of the roller seat 41 close to the positioning seat 9 is fixedly connected to the outer wall of the driving motor 2, and the inner wall of the roller seat 41 away from the positioning seat 9 is rotatably installed with a rope-releasing roller 42; when the device is performing cable detection, the cable to be detected will be wound around the rope-releasing roller 42, and one end of the cable is fixed on the winding roller 1, and when the driving motor 2 drives the winding roller 1 to rotate, the winding roller 1 will wind the cable, and the cable on the rope-releasing roller 42 will be wound around the winding roller 1, and the roller seat 41 provides conditions for the rotation of the winding roller 1 and the rope-releasing roller 42, thereby achieving the effect of cable movement.

[0032] like Figures 1 to 3 As shown, a base 43 is fixedly installed between the bottoms of the two roller seats 41, a support seat 44 is fixedly installed between the top of the base 43 and the bottom of the positioning seat 9, a plurality of support legs A45 are fixedly installed on the top of the base 43, the rotating shaft 7 is rotatably installed between the inner walls of the plurality of support legs A45, and a support leg B46 is fixedly installed between the top of the base 43 and the bottom of the slide seat 34; the device is supported by the base 43 to ensure the stability of the device when in use, and the positioning seat 9, the rotating shaft 7 and the slide seat 34 are supported respectively by the support seat 44, the support leg A45 and the support leg B46, so that each component is at a suitable height to facilitate the use of the device.

[0033] Working principle: Before the detection work is carried out, the one-way threaded rod 39 is driven to rotate by turning the adjusting knob 40. When the one-way threaded rod 39 rotates, it will drive the mounting plate 37 to move. When the mounting plate 37 moves, it will drive the detector 6 to move, thereby achieving the effect of adjusting the distance between the detector 6 and the cable. The device can adjust the distance between the detector 6 and the cable for cables of different diameters to ensure that the cable is detected at an appropriate distance, thereby ensuring the detection effect of the device. When performing the detection, one end of the cable to be detected is fixed on the winding roller 1, and then the drive motor 2 is started. The drive motor 2 drives the winding roller 1 to rotate to wind the cable, thereby driving the cable to move. When the cable is wound up by rotating, the winding roller 1 will drive the gear ring 3 to rotate, and when the gear ring 3 rotates, it will drive the gear 4 meshing with it to rotate along with it, and when the gear 4 rotates, it will drive the rotating shaft 7 to rotate, and when the rotating shaft 7 rotates, it will drive the transmission wheel 8 to rotate, and when the transmission wheel 8 rotates, it will drive the driven wheel 11 to rotate through the transmission belt 12, and when the driven wheel 11 rotates, it will drive the rotating ring 10 to rotate, and then drive the rotating positioning plate 5 to rotate, and the detector 6 is rotated around the cable by the rotation of the rotating positioning plate 5, and the cable is detected while the detector 6 rotates, so that the cable can be fully detected, and there is no need to detect the cable multiple times. The detection is convenient and comprehensive, and the detection efficiency is improved while ensuring the detection effect of the device.

[0034] During detection, the cable will pass between the ball bearings 16 on the inner sides of the rotating ring 10 and the supporting ring 13. In the initial state, the rotating plate 15 will be in an inwardly flipped state under the action of the arc-shaped elastic member 18. At this time, the ball bearings 16 on the same side will separate from each other, thereby facilitating the cable to pass through. After one end of the cable is passed through the ball bearing 16 and fixed on the winding roller 1, the rotating plate 15 is squeezed by adjusting the squeezing assembly. After the rotating plate 15 is squeezed, the arc-shaped elastic member 18 will shrink, thereby causing the rotating plate 15 to flip to both sides. When the rotating plate 15 is flipped to both sides, the ball bearings 16 on the same side will approach each other. The ball bearings 16 that are close together will squeeze the cable, thereby fixing the position of the cable, making the section of the cable below the detector 6 in a horizontal state, thereby keeping it parallel to the detector 6, and fixing the position of the cable by the ball bearing 16 to avoid The cable is prevented from deflecting during movement, thereby ensuring the detection effect of the device on the cable. The cable is fixed by the ball bearing 16. The ball bearing 16 can ensure that the cable can move under the action of the winding roller 1 while preventing the cable from rotating with the rotating ring 10, thereby ensuring the effectiveness of comprehensive detection. When the extrusion component is working, the bidirectional threaded rod 24 is driven to rotate by rotating the handle 25. When the bidirectional threaded rod 24 rotates, it will drive the two slides 20 to move synchronously to both sides. When the slide 20 moves, it will drive the positioning ring 22 to move through the support plate 21. When the positioning ring 22 moves to both sides, it will squeeze the rotating plates 15 on both sides, so that the ball bearings 16 on both sides are gathered together to position the cable, thereby achieving the effect of fixing the cable. Under the action of the bidirectional threaded rod 24, the distance between the ball bearings 16 can be adjusted, so that the device is suitable for cables of different diameters.

[0035] When the device is testing, the rotating shaft 7 drives the driving wheel 26 to rotate, and when the driving wheel 26 rotates, the driving shaft 27 drives the driving block 28 to rotate. When the driving block 28 rotates, it drives the hinge 30 to swing back and forth through the driving rod 29. When the hinge 30 swings, it drives the cleaning brush 33 to swing through the vertical plate 31 and the horizontal plate 32. The cable passes between the two cleaning brushes 33 during the transportation process. When the cleaning brush 33 swings, it cleans the surface of the cable to remove dirt and impurities on the surface of the cable, so as to avoid obstructions such as dirt and impurities from covering the defects on the surface of the cable, thereby improving the device. In order to improve the detection accuracy of the device, during the cleaning process, as the reciprocating swing of the cross plate 32, the extension block 35 will be driven to swing along, and the extension block 35 will drive the elastic stop block 36 to swing when it swings. The elastic stop block 36 will come into conflict with the cable when it swings. When the elastic stop block 36 passes over the cable due to deformation, the cable will vibrate due to a certain tension. The shaking of the cable can speed up the frequency of contact between the cable and the cleaning brush 33, so that the cleaning brush 33 can better clean the cable. At the same time, the cable can shake off impurities on its surface when it shakes, so that the detection effect of subsequent detection work is better.
