Description

Technical Field

[0001] The present invention relates to the technical field of cable insulation layer detection, and in particular to a cable insulation layer detection device and a method thereof. Background Art

[0002] In the field of modern power transmission, cables are the key carriers of power transmission, and the quality of their insulation layer is directly related to the safety and stable operation of the power system. With the continuous growth of power demand and the increasing complexity of cable application scenarios, higher requirements are placed on the accuracy, comprehensiveness and adaptability of cable insulation layer detection technology.

[0003] Traditional visual inspection methods are difficult to fully cover all angles of the cable insulation layer. It is very easy to miss the subtle and irregular surface defects on the cable insulation layer, such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, wrinkles, etc. At the same time, due to the large interference of external ambient light, without effective light shielding measures, the image quality obtained by the camera is poor, which seriously affects the accuracy of the inspection results.

[0004] Existing detection devices lack auxiliary visual detection methods, and existing detection devices can usually only detect a single position or a limited area. It is difficult to quickly adjust the detection angle and orientation, cannot meet different detection needs, and the detection efficiency is low.

[0005] Existing detection equipment has poor adaptability to cable length. Most clamping devices are of fixed specifications, and the clamping spacing and position cannot be flexibly adjusted according to the cable length. It is difficult to achieve stable clamping and transmission for cables of different lengths, which can easily cause the cable to shake or shift during the detection process, affecting the accuracy and stability of subsequent detection links. In addition, when defects are detected in the cable insulation layer, the existing technology lacks effective marking and secondary detection methods. Even if defects can be found, they cannot be clearly marked for subsequent processing, and it is even more impossible to conduct secondary accurate detection of the defective parts to further confirm the defect situation, which is not conducive to the analysis and repair of defective cables.

[0018] 2. The adaptive adjustment component of the transmission mechanism can flexibly adjust the spacing and position of the clamping transmission rollers according to the cable diameter.

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-12A cable insulation layer detection device shown is arranged on a work platform 2 and is used to detect the insulation layer of a cable 1. It includes a visual detection mechanism 3, a conflict detection mechanism 4, a marking mechanism 5 and a transmission mechanism 6. The visual detection mechanism 3 includes a first support frame 7, a detection camera 8, an annular light source 9, a first mounting plate 10, a light shield 11 and a light shielding tube 12. The first support frame 7 is installed on the work platform 2. The first mounting plate 10 and the detection camera 8 are each provided with three and are distributed in a ring around the axis of the insulation layer of the cable 1. The detection camera 8 is adjustable on the first support frame 7 through the first mounting plate 10. The light shielding tube 12 and the light shield 11 are respectively fixedly mounted on both sides of the first support frame 7. The detection end of the detection camera 8 extends into the light shield 11. The annular light source 9 is fixedly mounted on the light shield. Inside the light mask 11, the interference detection mechanism 4 is located next to the visual detection mechanism 3. The interference detection mechanism 4 includes a second support frame 13, a rotating disk 14, an interference detection component and a position adjustment component. The interference detection component is provided with several groups and is distributed in a ring around the rotating disk 14. The rotating disk 14 is rotatably mounted on the second support frame 13. The position adjustment component is installed on the working platform 2 and is transmission-connected with several groups of interference detection components. The marking mechanism 5 includes a paint pipeline 15, a brush 16 and a switching component. The brush 16 and the switching component are both installed on one group of the interference detection components. The brush 16 and the group of interference detection components are both transmission-connected with the switching component. The paint pipeline 15 is connected to the brush 16. The transmission mechanism 6 for transmitting the cable 1 is provided with two groups and is respectively located at both ends of the working platform 2.

[0024] The cable 1 is placed on the working platform 2, and the transmission mechanism 6 is started to smoothly feed the cable 1 into the equipment. The transmission mechanism 6 can flexibly adjust the clamping and driving mode according to the diameter of the cable 1 to ensure that cables 1 of different specifications can pass through the equipment smoothly for inspection. The visual inspection mechanism 3 is in operation, and the three inspection cameras 8 are distributed in a ring at an angle of 120 degrees around the axis of the insulation layer of the cable 1. According to the actual situation of the cable 1, the operator flexibly adjusts the position of the inspection camera 8 on the first support frame 7 through the first mounting plate 10 to shoot at the best angle and distance. The annular light source 9 lights up in the light shield 11 to provide stable light, and the light shield 11 and the light shielding tube 12 isolate external stray light. The inspection camera 8 quickly and accurately captures the image of the insulation layer of the cable 1 from multiple directions, and efficiently detects surface defects such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, wrinkles, etc., greatly improving the comprehensiveness and accuracy of the inspection.

[0025] The interference detection mechanism 4 is located beside the visual detection mechanism 3. As an auxiliary method to assist the visual detection mechanism 3, after the optical detection, a secondary detection is performed according to the result of the optical detection, and it can make actual contact with the area where defects may exist, so as to accurately judge the accuracy of the detection result. The rotating disk 14 on the second support frame 13 rotates, driving several groups of interference detection components distributed around it to rotate. The position adjustment component synchronously adjusts each group of interference detection components according to the diameter of the cable 1 to contact the insulation layer of the cable 1 with appropriate pressure. When there is a defect in the insulation layer, the pressure at the contact part changes, and the defect position is quickly detected. At the same time, the detection angle and orientation can be quickly adjusted to meet different detection needs.

[0026] The marking mechanism 5 plays a role when the visual inspection mechanism 3 and the interference detection component detect defects. The switching component works, so that the brush 16 installed on one set of the interference detection components is pushed forward and contacts the surface of the insulation layer of the cable 1. The paint pipe 15 is connected to the brush 16, and the interference detection component is rotated as a whole to achieve the coating mark of the defective part of the cable 1, which is convenient for subsequent processing. The equipment has a retraction function. After marking the defective part of the cable 1, the marked part can be retracted to the detection area of ​​the visual inspection mechanism 3, and then the marked position can be accurately detected by the detection camera 8. The coated mark has a light-absorbing effect, and has a higher contrast when re-detected, thereby achieving a more accurate detection function.

[0027] The interference detection assembly includes a second mounting plate 17, a sliding mounting seat 18, a sliding plate 19, a transmission rod 20 and a rotating ring 21. The second mounting plate 17 is fixedly mounted on the rotating disk 14. The axis of the rotating disk 14 is consistent with the axis of the cable 1. The sliding mounting seat 18 is slidably arranged on the second mounting plate 17. The sliding direction of the sliding mounting seat 18 is consistent with the radial length direction of the rotating disk 14. The sliding plate 19 is located on the side of the sliding mounting seat 18 close to the cable 1. The length direction of the transmission rod 20 is consistent with the sliding direction of the sliding mounting seat 18. The rotating ring 21 is slidably arranged at the outer edge of the rotating disk 14, the transmission rod 20 is transmission-connected with the sliding plate 19, the sliding plate 19 is provided with a pressure sensor 22 and a resistance ball seat 23, the resistance ball seat 23 is fixedly mounted on the pressure sensor 22, the transmission rod 20 is sleeved with a first spring 69, the first spring 69 is located on the sliding mounting seat 18, and an inclined resistance plate 24 is fixedly mounted on the sliding plate 19, and the inclined direction of the inclined resistance plate 24 is gradually away from the sliding plate 19 in the direction extending outward from the center of the rotating disk 14.

[0028] When the cable 1 is about to enter the area of ​​the interference detection component, the end of the cable 1 first interferes with the inclined interference plate 24. Since the inclined interference plate 24 is fixedly mounted on the sliding plate 19, this interference will push the inclined interference plate 24 and the sliding plate 19 connected thereto, causing them to move along the sliding mounting seat 18 in a direction away from the axis of the cable 1. In this process, the transmission rod 20, which is transmission-connected to the sliding plate 19, also moves synchronously, thereby compressing the first spring 69 sleeved on the transmission rod 20 and located on the sliding mounting seat 18. At the same time, the interference ball seat 23 on the sliding plate 19 also moves outward until it fits tightly with the outer wall of the cable 1. The pressure sensor 22 installed on the sliding plate 19 monitors the pressure at the contact point between the interference ball seat 23 and the insulation layer of the cable 1 in real time, and determines whether there is a defect in the insulation layer by the change in pressure.

[0029] The sliding plate 19 is also fixedly mounted with a first limiting rod 25 (such as Fig. 9 As shown), the first limiting rod 25 is slidably connected to the sliding mounting seat 18, and the transmission rod 20 is provided with a threaded section and a telescopic section. The threaded section is located at the end of the transmission rod 20 away from the cable 1, and the telescopic section is arranged at the end of the transmission rod 20 close to the cable 1. A rotatable lock buckle 26 is provided on the telescopic section. One end of the first spring 69 is fixedly connected to the sliding mounting seat 18, and the other end of the first spring 69 is transmission-connected to the rotatable lock buckle 26. A threaded seat 27 is fixedly installed at the end of the sliding mounting seat 18 away from the cable 1, and the threaded seat 27 is threadedly connected to the threaded section of the transmission rod 20, and the position adjustment component is transmission-connected to the transmission rod 20.

[0030] The position adjustment component mainly realizes the position adjustment of the sliding mounting seat 18 by driving the transmission rod 20 to rotate. When the position adjustment component is working, the transmission rod 20 starts to rotate, and its threaded section cooperates with the threaded seat 27. Since the threaded seat 27 is fixedly mounted on the end of the sliding mounting seat 18 away from the cable 1, the rotation of the transmission rod 20 enables the sliding mounting seat 18 to slide relative to the second mounting plate 17, thereby realizing the precise adjustment of the position of the sliding mounting seat 18. On the one hand, the rotatable lock 26 ensures the effective transmission between the first spring 69 and the transmission rod 20, so that the first spring 69 can be compressed and rebounded normally when the transmission rod 20 is displaced; on the other hand, the rotatable lock 26 will not hinder the rotation of the transmission rod 20, ensuring that the transmission rod 20 can rotate normally according to the drive of the position adjustment component. When the contact pressure between the contact ball seat 23 and the insulation layer of the cable 1 changes, the telescopic section can be elastically compressed according to the pressure change, and this elastic change can maintain the close contact between the contact ball seat 23 and the insulation layer of the cable 1. Even if there are slight unevenness or pressure fluctuations on the surface of the insulation layer of the cable 1, the telescopic section of the transmission rod 20 can be adjusted in time to ensure that the pressure detected by the pressure sensor 22 always accurately reflects the actual value of the insulation layer of the cable 1, thereby improving the stability and reliability of the entire detection process.

[0031] The position adjustment component drives the transmission rod 20 to rotate by the relative rotation of the rotating ring 21 and the rotating disk 14. The transmission rod 20 is provided with a threaded section and a telescopic section, and the threaded section is located at the end away from the cable 1. When the rotating ring 21 and the rotating disk 14 rotate relative to each other, the transmission rod 20 rotates, and its threaded section cooperates with the threaded seat 27 fixedly mounted on the end of the sliding mounting seat 18 away from the cable 1, driving the sliding mounting seat 18 to slide along the second mounting plate 17. This design can accurately adjust the position of the sliding mounting seat 18 according to the different diameters of the cable 1, thereby ensuring that the contact ball seat 23 contacts the cable 1 with the best pressure, greatly improving the accuracy of the detection, and this adjustment method can synchronize and accurately adjust multiple sliding mounting seats 18. The first limit rod 25 is fixedly mounted on the sliding plate 19 and is slidably connected to the sliding mounting seat 18, ensuring the stability of the sliding plate 19 during the sliding process. The rotatable lock buckle 26 is arranged on the telescopic section of the transmission rod 20, which can ensure the effective transmission of the first spring 69 and the transmission rod 20 while not hindering the normal rotation of the transmission rod 20. The telescopic section of the transmission rod 20 can realize the elastic compression function. When the contact pressure between the resistance ball seat 23 and the insulation layer of the cable 1 changes, the telescopic section can automatically adjust to always maintain close contact between the resistance ball seat 23 and the insulation layer of the cable 1, ensuring the continuous accuracy of pressure detection.

[0032] The interference detection mechanism 4 also includes a rotation drive component, which includes a first rotation drive 28, a rotating shaft 29, a sliding ring 30 and a transmission gear 31. The first rotation drive 28 is fixedly installed on the working platform 2. The rotating shaft 29 is horizontally arranged and one end is fixedly connected to the output end of the first rotation drive 28. The length direction of the rotating shaft 29 is consistent with the axial direction of the cable 1. The sliding ring 30 is slidably arranged on the rotating shaft 29. The transmission gear 31 is fixedly installed on the sliding ring 30. The inner wall of the sliding ring 30 is provided with a latch tooth 32. The outer wall of the rotating shaft 29 is provided with a first horizontal sliding groove 33 that cooperates with the latch tooth 32 along its length direction. The outer edge of the rotating disk 14 is provided with a first ring tooth 34. The outer edge of the rotating ring 21 is provided with a second ring tooth 35. The first ring tooth 34 and the second ring tooth 35 are both engaged with the transmission gear 31.

[0033] When the first rotary driver 28 drives the rotating shaft 29 to rotate, the sliding ring 30 rotates with the rotating shaft 29, and then drives the transmission gear 31 to rotate. Since the transmission gear 31 is engaged with the first ring gear 34 and the second ring gear 35 at the same time, the rotating disk 14 and the rotating ring 21 will rotate synchronously. In this case, the relative position of the sliding mounting seat 18 and the second mounting plate 17 will not change, and the interference detection component maintains the current detection position and state.

[0034] The position adjustment component includes a driven gear 36, a second linear drive 37, a push plate 38, a friction plate 39 and a third spring 40. There are several driven gears 36, and the several driven gears 36 correspond one by one to several groups of interference detection components. The second linear drive 37 is fixedly installed on the working platform 2, and the output end of the second linear drive 37 is fixedly connected to the push plate 38, and the push plate 38 is fixedly connected to the sliding collar 30. The third spring 40 is sleeved on the rotating shaft 29, one end of the third spring 40 is fixedly connected to the end of the rotating shaft 29, and the other end of the third spring 40 is fixedly connected to the end of the sliding collar 30. The friction plate 39 is fixedly installed at the top of the push plate 38 on the side close to the rotating disk 14, and the third ring teeth 41 are fixedly installed on the outer wall of the rotating ring 21. Several driven gears 36 are meshed with the third ring teeth 41, and the driven gear 36 is fixedly connected to the end of the transmission rod 20 away from the interference ball seat 23.

[0035] When the position of the sliding mount 18 needs to be adjusted, the second linear driver 37 pushes the push plate 38, driving the sliding collar 30 to move along the rotating shaft 29, so that the transmission gear 31 only engages with the second ring gear 35 and disengages from the first ring gear 34. At this time, when the first rotary driver 28 continues to work and drives the rotating shaft 29 to rotate, the rotation of the transmission gear 31 will only drive the rotating ring 21 to rotate relative to the rotating disk 14. The rotation of the rotating ring 21 drives the sliding mount 18 to slide on the second mounting plate 17 through the connection with the transmission rod 20, thereby realizing the adjustment of the position of the sliding mount 18. This design provides a convenient and accurate adjustment method for the interference detection component to adapt to different cable 1 diameters. The operator can quickly and accurately adjust the position of the interference detection component according to the actual detection needs, thereby improving the efficiency and flexibility of the detection work.

[0036] The output end of the second linear drive 37 pushes the push plate 38 to switch the position of the transmission gear 31 on the sliding collar 30, from meshing with the first ring teeth 34 of the rotating disk 14 and the second ring teeth 35 of the rotating ring 21 at the same time, to meshing with only the second ring teeth 35 of the rotating ring 21, thereby realizing the effective switching of the position of the transmission gear 31. When the second linear drive 37 does not provide driving force, the third spring 40 plays a role to ensure that the positions of the various components of the device are stable when the position adjustment is not performed, and the interference detection component can perform the detection work normally. When the transmission gear 31 is disengaged from the first ring teeth 34, the friction plate 39 fits with the rotating disk 14, and uses friction to prevent the rotating disk 14 from offset rotation when the transmission gear 31 only drives the rotating ring 21 to rotate. This design ensures that the rotating ring 21 can rotate accurately, and avoids affecting the accuracy of the position adjustment of the sliding mounting seat 18 due to the unstable rotation of the rotating disk 14. A third ring tooth 41 is fixedly mounted on the outer wall of the rotating ring 21, and a plurality of driven gears 36 are meshed with the third ring tooth 41, and the driven gear 36 is fixedly connected to one end of the transmission rod 20 away from the interference ball seat 23. When the rotating ring 21 rotates, it drives a plurality of driven gears 36 to rotate synchronously through the third ring tooth 41, and the rotation of the driven gear 36 then drives the transmission rod 20 connected thereto to rotate. Since a plurality of transmission rods 20 are respectively connected to a plurality of groups of interference detection components, synchronous position adjustment of a plurality of groups of interference detection components is achieved. This synchronous adjustment method greatly improves the detection efficiency, ensuring that when facing cables 1 with different diameters, a plurality of interference detection components can be adjusted to a suitable position at the same time, thereby ensuring the coordination and efficiency of the detection work.

[0037] The switching assembly includes a synchronous mounting frame 42, a first linear drive 43, a transmission plate 44, a transmission ring 45, a first hinged seat 46, a second hinged seat 47 and a compression strut 48. The synchronous mounting frame 42 is fixedly connected to the sliding plate 19. The synchronous mounting frame 42 is located at the end of the sliding mounting seat 18 away from the cable 1. The first linear drive 43 is fixedly mounted on the synchronous mounting frame 42. The output end of the first linear drive 43 is fixedly connected to the transmission plate 44. The transmission plate 44 is slidably set on the paint pipe 15. Two transmission rings 45 are provided on the paint pipe 15. The two transmission rings 45 are both located in the sliding mounting seat 18. The transmission plate 44 is set between the two transmission rings 45. The first hinged seat 46 is fixedly mounted on the end of the paint pipe 15 close to the brush 16. The second hinged seat 47 is fixedly mounted on the end of the transmission rod 20 close to the cable 1. The two ends of the compression strut 48 are respectively hinged to the first hinged seat 46 and the second hinged seat 47. The compression strut 48 is composed of a telescopic rod 49 and a second spring 50.

[0038] In the initial state of the marking mechanism 5, the transmission rod 20 is in an extended state, and the paint pipe 15 is in a retracted state. The compression support rod 48 is composed of a telescopic rod 49 and a second spring 50, and its two ends are respectively hinged to a first hinge seat 46 fixedly installed at one end of the paint pipe 15 close to the brush 16 and a second hinge seat 47 fixedly installed at one end of the transmission rod 20 close to the cable 1. At this time, the compression support rod 48 is opened, so that the paint pipe 15 and the transmission rod 20 are in a stable state.

[0039] When it is detected that there are defects in the insulation layer of the cable 1 and it needs to be marked, the first linear drive 43 pushes the transmission plate 44 to slide on the paint pipe 15. The transmission plate 44 slides until it contacts one of the transmission rings 45, and pushes the paint pipe 15 toward the cable 1 through the transmission plate 44 and the transmission ring 45. As the paint pipe 15 moves, the compression strut 48 is squeezed, the telescopic rod 49 shrinks, the second spring 50 is compressed, and the compression strut 48 changes its tilt direction. When the paint pipe 15 moves to a suitable position, the compression strut 48 reopens under the elastic force of the second spring 50, and the paint pipe 15 extends at this time, and the transmission rod 20 retracts (the compression strut 48 is designed to be compressible to prevent it from getting stuck during switching, and it will automatically open after the reversal is completed without providing additional power to maintain the state after the reversal). The originally retracted paint brush 16 fits with the cable 1, and the originally extended contact ball seat 23 at the corresponding position retracts, completing the switch from the detection function to the marking function. This design cleverly utilizes the transmission relationship between the various components to achieve fast and smooth switching between detection and marking functions, and can maintain stability when both functions are implemented.

[0040] There is a gap between the two transmission rings 45, which provides a certain horizontal displacement adjustment space for the transmission rod 20. When the transmission rod 20 is displaced, due to the existence of the gap, it will not interfere with the transmission plate 44, ensuring that the switching assembly can operate stably, avoiding failures caused by interference between components, and improving the reliability of the marking mechanism 5.

[0041] The paint pipeline 15 is composed of a straight pipe 51, a bellows 52, a first connecting pipe 53, an annular channel 54 and a second connecting pipe 55. The straight pipe 51 is horizontally slidably arranged on the sliding mounting seat 18. One end of the straight pipe 51 close to the cable 1 is connected to the paint brush 16. The other end of the straight pipe 51 is connected to the first connecting pipe 53 through the bellows 52. The first connecting pipe 53 is provided with a solenoid valve. The switching component is connected to the straight pipe 51 in a transmission manner. The annular channel 54 is fixedly installed at the center of the rotating disk 14. One end of the first connecting pipe 53 away from the straight pipe 51 is connected to the annular channel 54. The second connecting pipe 55 (such as Figure 5 One end of the second connecting pipe 55 is connected to the annular channel 54, and the other end of the second connecting pipe 55 passes through the second support frame 13 and is connected to an external paint source.

[0042] When it is detected that there are defects in the insulation layer of the cable 1 that need to be marked, the switching component starts to push the straight tube 51 to slide horizontally on the sliding mounting seat 18. When the switching component is actuated, the straight tube 51 slides in the direction close to the cable 1, so that the paint brush 16 is close to the surface of the insulation layer of the cable 1. At this time, the paint in the external paint source enters the annular channel 54 through the second connecting tube 55, and then enters the straight tube 51 through the first connecting tube 53 and the corrugated tube 52, and is finally coated on the defective part of the cable 1 by the paint brush 16. The design of the annular channel 54 ensures that the paint pipeline 15 is in a connected state when rotated to any angle. The corrugated tube 52 has good flexibility and can adapt to the displacement changes of the straight tube 51 during the sliding process, ensuring the smoothness of the paint transmission.

[0043] The transmission mechanism 6 includes a third support frame 56, a clamping transmission roller 57, a sliding block 58 and an adaptive adjustment component. The third support frame 56 is fixedly installed on the working platform 2. Two clamping transmission rollers 57 and two sliding blocks 58 are symmetrically arranged along the vertical center plane. The adaptive adjustment component is transmission-connected to the two sliding blocks 58. The clamping transmission roller 57 is fixedly connected to the sliding block 58. A second horizontal slide groove 59 is horizontally arranged on the third support frame 56 for the sliding block 58 to slide.

[0044] The third support frame 56 of the transmission mechanism 6 is fixed on the working platform 2, and the two sliding blocks 58 slide along the second horizontal slide groove 59 on the third support frame 56. The adaptive adjustment component drives the sliding block 58 to move according to the diameter of the cable 1, drives the fixedly connected clamping transmission roller 57 to move, and adjusts the clamping position. The clamping transmission roller 57 has a small center diameter and gradually increases the diameter at both ends. It can adapt to cables 1 with different diameters, stably clamp and transmit the cable 1, ensure that the cable 1 moves smoothly during the detection process, and provide a good foundation for subsequent detection links.

[0045] The adaptive adjustment component includes a lifting cylinder 60, a lifting plate 61, a first hinged link 62, a second hinged link 63, a horizontal extension plate 64, a sliding seat 65, a second rotary driver 66, a rotating wheel 67 and a synchronous transmission belt 68. The lifting cylinder 60 is fixedly installed on the working platform 2, and the lifting plate 61 is vertically slidably arranged. The output end of the lifting cylinder 60 is fixedly connected to the lifting plate 61. Two first hinged links 62 are provided and correspond to two sliding blocks 58 one by one. One end of the first hinged link 62 is hinged to the lifting plate 61, and the other end of the first hinged link 62 is hinged to the sliding block 58. The horizontal extension plate 64 is fixedly installed on the third support frame 56. The length direction of the horizontal extension plate 64 is consistent with the axial direction of the cable 1. The horizontal extension plate 64 is provided with a third horizontal slide groove consistent with its length direction. The sliding seat 65 is slidably set in the third horizontal slide groove. One end of the second hinged link 63 is hinged to the lifting plate 61, and the other end of the second hinged link 63 is hinged to the sliding seat 65. The sliding seat 65 is provided with two rotating wheels 67 connected by meshing gears. The second rotation driver 66 is fixedly installed on the sliding seat 65. The output end of the second rotation driver 66 is connected to one of the rotating wheels 67. The two rotating wheels 67 are connected to the two clamping transmission rollers 57 through two synchronous transmission belts 68 respectively.

[0046] When it is necessary to adjust the clamping and transmission state of the transmission mechanism 6 according to the length of the cable 1, the adaptive adjustment component starts to work. First, the lifting cylinder 60 is started. The lifting cylinder 60 is fixedly installed on the working platform 2, and its output end pushes the lifting plate 61 to slide vertically upward. The lifting plate 61 is hinged with the two sliding blocks 58 through the first hinged connecting rod 62. When the lifting plate 61 rises, the first hinged connecting rod 62 drives the two sliding blocks 58 to slide in the second horizontal slide groove 59 of the third support frame 56, thereby adjusting the distance between the two clamping transmission rollers 57 so that it can adapt to cables 1 with different lengths. At the same time, the lifting plate 61 is also hinged with the sliding seat 65 through the second hinged connecting rod 63. When the lifting plate 61 rises, the second hinged connecting rod 63 drives the sliding seat 65 to slide in the third horizontal slide groove. When the second rotary driver 66 works, it drives the rotating wheel 67 connected thereto to rotate, and through the transmission of the meshing gear, the other rotating wheel 67 also rotates synchronously in the opposite direction. The two rotating wheels 67 are respectively connected to the two clamping transmission rollers 57 through two synchronous transmission belts 68. The rotation of the rotating wheel 67 drives the clamping transmission rollers 57 to rotate through the synchronous transmission belts 68, thereby realizing stable transmission of the cable 1. The synchronous transmission belts 68 can ensure that a stable rotational driving force is provided when clamping cables 1 of different diameters.

[0047] The various parts of the adaptive adjustment component work together to accurately adjust the clamping and transmission state of the transmission mechanism 6 according to the diameter of the cable 1. Through the mutual cooperation of the lifting cylinder 60, the lifting plate 61, the first hinged link 62, the second hinged link 63, the sliding seat 65, the second rotary driver 66, the rotating wheel 67 and the synchronous transmission belt 68, it can efficiently adapt to different diameters of the cable 1, improve the stability and reliability of the transmission process, and ensure that the cable 1 can pass through the transmission mechanism 6 smoothly and steadily and enter the subsequent detection link.

[0048] A method for detecting a cable insulation layer comprises the following steps: S1: Place the cable 1 on the working platform 2, start the transmission mechanism 6, and adjust the spacing and position of the clamping transmission rollers 57 through the adaptive adjustment component according to the diameter of the cable 1, stably clamp the cable 1, and smoothly send it into the internal detection area of ​​the equipment; S2: When the cable 1 enters the area of ​​the visual inspection mechanism 3, the visual inspection mechanism 3 is turned on. The operator adjusts the position of the inspection camera 8 according to the actual situation of the cable 1, and the ring light source 9 lights up. The three inspection cameras 8 are distributed in a ring at an angle of 120 degrees around the axis of the insulation layer of the cable 1, and the insulation layer image of the cable 1 is captured quickly and accurately from multiple directions to detect surface defects such as rupture, overlap, bulge, dent, pinhole, crack, wrinkle, etc. S3: The cable 1 continues to be transmitted to the area of ​​the conflict detection mechanism 4, and the conflict detection mechanism 4 is started. The position adjustment component drives the rotating ring 21 according to the diameter of the cable 1, and synchronously adjusts the positions of the multiple sliding mounting seats 18, so that the conflict detection component conflicts with the insulation layer of the cable 1 with appropriate pressure. The conflict detection component rotates with the rotating disk 14, and the pressure sensor 22 monitors the pressure change of the conflicting part, accurately determines the defect position of the insulation layer, completes the secondary inspection, and verifies the visual inspection result; S4: If the visual inspection mechanism 3 and the interference detection component detect that there are defects in the insulation layer of the cable 1, the marking mechanism 5 starts to work, the switching component pushes the brush 16 to contact the surface of the insulation layer of the cable 1, the paint pipe 15 is connected to the brush 16, and the interference detection component is rotated as a whole to apply a coating mark to the defective part of the cable 1. Subsequently, the equipment retraction function is activated to retract the marked part to the detection area of ​​the visual inspection mechanism 3, and the detection camera 8 accurately detects the coating mark position again, using the light absorption effect of the mark to improve the contrast and further confirm the defect; S5: After the detection is completed, the transmission mechanism 6 sends the detected cable 1 out of the device, and the detection process ends.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
