Description

Technical Field

[0001] This invention relates to the field of high-voltage cable technology, specifically to an automatic stripping device and method for the insulation and shielding of high-voltage cables. Background Technology

[0002] In the process of laying power cables and installing accessories, the stripping of the cable insulation shield is one of the key procedures to ensure the quality of cable terminals and intermediate joints. High-voltage cables typically consist of multiple layers, including conductors, insulation layers, insulation shields, and outer sheaths. The quality of the stripping of the insulation shield (also known as the outer semiconductive layer) directly affects the subsequent installation of stress cones and the uniformity of the electric field distribution.

[0003] Currently, the stripping of high-voltage cable insulation shielding layers mainly relies on manual operation. Common methods include using specialized cable stripping knives for spiral feed cutting, or manually scraping with tools such as glass blades. These traditional methods have the following shortcomings: 1. Manual operation makes it difficult to achieve a uniform stripping depth, which can easily leave knife marks of varying depths on the cable surface, affecting the flatness of the insulation layer and increasing the difficulty and time cost of subsequent polishing processes.

[0004] 2. The peeling and subsequent grinding processes are time-consuming and require a high level of technical proficiency from the operators, making it difficult to meet the needs of large-scale, high-efficiency construction.

[0005] 3. The results of different operators or the same person operating at different times may vary greatly, resulting in unstable cable pretreatment quality, which affects the reliability of accessory installation and long-term operational safety. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems and provide an automatic stripping device and method for high-voltage cable insulation shielding. This stripping device and method can achieve high-precision, high-efficiency, and automated stripping of high-voltage cable insulation shielding, which is of great significance for improving the installation quality of cable accessories, reducing reliance on manual labor, and ensuring the reliability of power grid operation.

[0007] The objective of this invention is achieved through the following technical solution: An automatic stripping device for high-voltage cable insulation shielding includes a traveling mechanism for traveling on the high-voltage cable and a stripping mechanism for precisely stripping the insulation shielding layer of the high-voltage cable. The peeling mechanism is fixedly connected to the walking mechanism. The peeling mechanism includes a rotary peeling cylinder, a peeling blade, a synchronous centering mechanism, and a rotary peeling drive mechanism. The rotary cutting cylinder is poweredly connected to the drive end of the rotary cutting drive mechanism; The synchronous centering mechanism includes a synchronous linkage positioning component and a positioning drive component. The synchronous linkage positioning component has at least three sets and is evenly arranged in a circle around the center of the rotary cutting cylinder in the inner cavity of the rotary cutting cylinder. Each set of synchronous linkage positioning components includes a synchronous linkage positioning frame, a synchronous centering wheel, and a synchronous linkage rod. The synchronous centering wheel is rotatably connected to the synchronous linkage positioning frame, and the two ends of the synchronous linkage rod are rotatably connected to the synchronous linkage positioning frames of two adjacent sets of synchronous linkage positioning components. The driving end of the positioning drive component is fixedly connected to the synchronous linkage positioning frame of one set of synchronous linkage positioning components. Before the stripping begins, the positioning drive component drives the synchronous linkage positioning frame to swing, causing all synchronous centering wheels to press synchronously onto the cable. The peeling blade is located outside the rotary cutting cylinder and is directly or indirectly connected to the synchronous linkage positioning frame of one of the synchronous linkage positioning components.

[0008] In a preferred embodiment of the present invention, the synchronous linkage positioning frame is rotatably connected to the inner wall of the rotary cutting cylinder. The synchronous linkage positioning frame is provided with a centering wheel mounting hole and a linkage mounting hole. The synchronous centering wheel is rotatably connected in the centering wheel mounting hole, and there are two linkage mounting holes. One end of the synchronous linkage rod is rotatably connected to one of the linkage mounting holes of the synchronous linkage positioning frame in the same group, and the other end of the synchronous linkage rod is rotatably connected to one of the linkage mounting holes of the synchronous linkage positioning frame in an adjacent group. The positioning drive assembly is located on the outside of the rotary cutting cylinder. The positioning drive assembly includes a positioning drive screw, a transmission swing arm, and a rotating nut. One end of the transmission swing arm is fixedly connected to the synchronous linkage positioning frame of one of the synchronous linkage positioning assemblies. The other end of the transmission swing arm is rotatably connected to the tail of the positioning drive screw. The rotating nut is rotatably connected to the outer surface of the rotary cutting cylinder. The head of the positioning drive screw is connected to the rotating nut through a threaded structure. With the above structure, the cable to be circumcised is first passed through the inner cavity of the slitting cylinder. Then, the positioning drive screw is rotated in the corresponding direction. The positioning drive screw drives the transmission swing arm to swing in the corresponding direction. The transmission swing arm then transmits power to the corresponding synchronous linkage positioning frame, causing the synchronous linkage positioning frame to rotate and bring the corresponding synchronous centering wheel closer to the cable. At the same time, since there are synchronous linkage rods between adjacent synchronous linkage positioning frames, that is, all synchronous linkage positioning frames are linked, so all synchronous centering wheels will move synchronously towards the cable, achieving synchronous positioning. This ensures that the circular outline of the cable is accurately determined during the stripping process, thereby greatly improving the accuracy and consistency of the stripping path. At this time, the stripping blade is also placed in a relatively ideal position along with one of the synchronous linkage positioning frames, waiting to start the circumcising.

[0009] In a preferred embodiment of the present invention, two synchronous centering wheels are provided in the same group, and the arrangement direction of the two synchronous centering wheels is parallel to the axial direction of the rotary cutting cylinder. The axial direction of the synchronous centering wheels is parallel to the axial direction of the rotary cutting cylinder. With this structure, not only can the cable be accurately positioned, but it can also be straightened, making the rotary cutting operation smoother and more consistent.

[0010] In a preferred embodiment of the present invention, the peeling mechanism further includes a pose adjustment mechanism for adjusting the relative pose of the peeling blade. The pose adjustment mechanism includes a first adjustment component and a second adjustment component. The first adjustment component is fixedly connected to the synchronous linkage positioning frame, and the second adjustment component is fixedly connected to the first adjustment component. The peeling blade is fixedly mounted on the second adjustment component. The first adjustment assembly includes a first adjustment mounting base, an intermediate mounting block, an adjustment screw, and an adjustment nut. The first adjustment mounting base is fixedly connected to the synchronous linkage positioning frame. One end of the intermediate mounting block is rotatably connected to the first adjustment mounting base, and the other end of the intermediate mounting block is rotatably connected to the tail of the adjustment screw. The head of the adjustment screw is connected to the adjustment nut through a threaded structure, and the adjustment nut is rotatably connected to the outer surface of the rotary cutting cylinder. The second adjustment assembly includes a second adjustment mounting base, a sliding block, and a locking bolt. The second adjustment mounting base is fixedly connected to the first adjustment mounting base. The second adjustment mounting base has a sliding groove. One end of the sliding block is slidably connected in the sliding groove, and the other end of the sliding block is fixedly connected to the peeling blade. The side wall of the second adjustment mounting base has an operation clearance window. The locking bolt passes through the operation clearance window and is connected to the sliding block located in the sliding groove to lock the sliding block.

[0011] With the above structure, after completing the positioning operation, observe whether the posture or angle of the stripper is feasible. If adjustment is needed, rotate the adjusting screw in the corresponding direction. The power is transmitted from the middle mounting block to the first adjusting mounting seat, causing the first adjusting mounting seat to rotate around its own rotation center to adjust the orientation (angle) of the stripper to meet the current needs. Further, confirm the relative height difference between the stripper and the cable, i.e., confirm the stripping depth. If the stripping depth needs adjustment, first loosen the locking bolt, then move the sliding block in the corresponding direction until the stripper is at the desired relative height, and finally fix it with the locking bolt. In this way, the position and posture of the stripper can be adjusted according to different cable sizes to obtain a more ideal circumferential cutting effect.

[0012] In a preferred embodiment of the present invention, the cutting edge of the stripping blade is inclined along the axial direction of the rotary cutting cylinder. This specially designed inclined blade structure allows for a smooth, arc-shaped transition of the cut surface when cutting the shielding layer, effectively controlling the surface roughness to below 7μm. Furthermore, the sloped fracture structure formed by the inclined blade facilitates subsequent processes such as insulation restoration and semi-conductive layer treatment, solving the industry pain points of inaccurate stripping thickness control and uneven cut surfaces commonly encountered in manual operations. This enables automatic and efficient processing of smooth shielded cuts that meet high installation standards, improving overall cable installation quality and operational reliability.

[0013] In a preferred embodiment of the present invention, the rotary cutting drive mechanism includes a rotary cutting mounting base, a rotary cutting drive motor, and a rotary cutting transmission assembly. The rotary cutting mounting base is fixedly connected to the housing of the rotary cutting drive motor. The rotary cutting transmission assembly includes a rotary cutting drive gear and a rotary cutting driven gear. The rotary cutting drive gear is connected to the output shaft of the rotary cutting drive motor, and the rotary cutting driven gear is rotatably connected to the rotary cutting mounting base. The rotary cutting driven gear is coaxially and fixedly connected to the rotary cutting cylinder. With the above structure, the rotary cutting cylinder can rotate under the drive of the rotary cutting drive motor, thereby driving the peeling blade to perform rotary cutting operations.

[0014] In a preferred embodiment of the present invention, the walking mechanism includes a walking mounting housing, a walking roller, a clamping drive mechanism, and a rolling drive mechanism; The traveling roller is installed inside the traveling mounting housing, and there are two sets of traveling rollers distributed vertically opposite each other. The clamping drive mechanism includes a clamping drive motor and a clamping transmission assembly. The clamping drive motor is fixedly mounted below the walking mounting housing. The clamping transmission assembly includes a clamping gear transmission assembly and a clamping screw transmission assembly. The clamping gear transmission assembly includes a clamping drive gear and a clamping driven gear. The clamping drive gear is connected to the output shaft of the clamping drive motor. There are two sets of clamping driven gears, which are respectively located on both sides of the clamping drive gear. There are two sets of clamping screw transmission assemblies, which are respectively located on both sides of the walking roller. Each set of clamping screw transmission assemblies includes a clamping transmission seat, a clamping transmission screw, and a clamping transmission screw nut. There are two clamping transmission seats and two clamping transmission screw nuts in the same set. The ends of the two sets of walking rollers are rotatably connected to the two clamping transmission seats. The clamping transmission screw is a bidirectional screw. The two helical structures of the bidirectional screw with different directions of rotation are respectively engaged with the two clamping transmission screw nuts. The two clamping transmission screw nuts are fixedly mounted on the two clamping transmission seats. The rolling drive mechanism is provided in two sets and located on both sides of the clamping drive mechanism. Each set of rolling drive mechanisms includes a rolling drive motor and a rolling transmission assembly. The rolling drive motor is indirectly mounted on one of the clamping transmission seats in the same set. The rolling transmission assembly includes a right-angle transmission assembly and a transmission shaft. The right-angle transmission assembly is poweredly connected between the rolling drive motor and the transmission shaft. The transmission shaft is fixedly connected to the traveling roller.

[0015] With the above structure, after the cable passes between the two sets of traveling rollers, the clamping drive motor is activated. The clamping gear transmission assembly divides the power into two paths and transmits them to the two sets of clamping screw transmission assemblies. This causes the clamping transmission screws of the two sets of clamping screw transmission assemblies to rotate, which in turn causes the two clamping transmission seats to move towards each other until the two sets of rolling rollers clamp the cable. Then, the rolling drive motor is activated, and the right-angle transmission assembly and transmission shaft transmit the power to the traveling rollers, causing the traveling rollers to roll. This allows the rollers to travel on the cable, and the stripping mechanism continuously strips the insulation shielding layer of the high-voltage cable.

[0016] An automatic stripping method for the insulation shield of high-voltage cables includes the following steps: (1) Pass the high-voltage cable through the traveling rollers of the traveling mechanism and the inner cavity of the peeling cylinder of the peeling mechanism, so that the whole device is mounted on the cable; (2) The synchronous linkage positioning frame of one group of synchronous linkage positioning components is driven to swing by the positioning drive component. The synchronous linkage rod drives the other groups of synchronous linkage positioning frames to swing synchronously, so that all synchronous centering wheels press against the outer surface of the cable at the same time, realizing the automatic centering of the device and the cable, ensuring that the rotary cutting cylinder is coaxial with the cable, and the stripping blade connected to the synchronous linkage positioning frame swings to the initial cutting position together. (3) The cutting angle and cutting depth of the stripper are adjusted by the position adjustment mechanism. First, the tilt angle of the stripper blade relative to the cable surface is adjusted, and then the stripping depth of the stripper is adjusted. (4) Start the clamping drive mechanism, drive the two sets of clamping screw drive components through the clamping transmission components, so that the upper and lower sets of traveling rollers move towards each other and clamp on the cable surface, providing a stable clamping force for the device to move along the cable axis; (5) Start the rolling drive mechanism and the rotary cutting drive mechanism. The rolling drive mechanism drives the traveling roller to rotate so that the device moves at a constant speed along the cable axis. The rotary cutting drive mechanism drives the rotary cutting cylinder to rotate and drives the stripping blade to rotate and cut around the circumference of the cable. The spiral continuous stripping of the insulation shielding layer is achieved through the combined motion of axial movement and rotary cutting. (6) When the device travels to the preset stripping length, stop the rolling drive mechanism and the rotary cutting drive mechanism, reverse drive the clamping drive mechanism to release the traveling roller, reverse drive the positioning drive assembly to make the synchronous centering wheel disengage from the cable, and remove the device from the cable to complete the stripping operation.

[0017] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting up a synchronous centering mechanism, utilizes the linkage structure of multiple sets of synchronously linked positioning components and synchronous linkage rods. Under the drive of the positioning drive component, all synchronous centering wheels can swing synchronously and press against the cable, accurately determining the circular outline of the cable and ensuring that the device is coaxial with the cable. This provides a stable cutting reference for the stripping blade, effectively solving the problems of inconsistent stripping depth and uneven blade mark depth commonly encountered in manual operation. Simultaneously, it can precisely control surface flatness, reducing the difficulty and time of subsequent grinding processes and avoiding irreversible damage to the cable insulation layer caused by over-grinding.

[0018] 2. The stripping blade of the present invention is connected to one of the synchronous linkage positioning components, so that the feeding action of the stripping blade is related to the clamping action of the centering mechanism. After the centering wheel presses the cable and determines the center, the stripping blade can stably and accurately cut the insulation shielding layer along the predetermined trajectory, avoiding measurement and execution errors caused by cable bending or deformation, and significantly improving the consistency of stripping quality.

[0019] 3. The walking mechanism of this invention drives the entire device to move automatically on the cable. Combined with the rotary cutting drive mechanism to drive the rotary cutting cylinder to rotate, the peeling process is automated. There is no need for manual hand-held blades for spiral feeding or scraping, which greatly reduces the labor intensity of operators and the reliance on skilled experience, improves construction efficiency, and meets the needs of large-scale and high-efficiency construction.

[0027] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0028] Example 1 Combination Figures 1-7 The high-voltage cable insulation shield automatic stripping device of this embodiment includes a traveling mechanism for moving on the high-voltage cable and a stripping mechanism for precisely stripping the insulation shield layer of the high-voltage cable. The stripping mechanism is fixedly connected to the traveling mechanism and includes a rotary cutting cylinder 1, a stripping blade 2, a synchronous centering mechanism, and a rotary cutting drive mechanism. The rotary cutting cylinder 1 is poweredly connected to the drive end of the rotary cutting drive mechanism. The synchronous centering mechanism includes a synchronous linkage positioning component and a positioning drive component. The synchronous linkage positioning component has at least three sets and is evenly arranged in a circular pattern around the center of the rotary cutting cylinder 1 in the inner cavity of the rotary cutting cylinder 1 (this embodiment has four sets to achieve four-point centering and positioning operation). Each set of synchronous linkage positioning components includes a synchronous linkage positioning frame 3, a synchronous centering wheel 4, and a synchronous linkage rod 5. The synchronous centering wheel 4 is rotatably connected to the synchronous linkage positioning frame 3, and the two ends of the synchronous linkage rod 5 are rotatably connected to the synchronous linkage positioning frames 3 of two adjacent sets of synchronous linkage positioning components. The driving end of the positioning drive component is fixedly connected to the synchronous linkage positioning frame 3 of one set of synchronous linkage positioning components. Before the peeling begins, the positioning drive component drives the synchronous linkage positioning frame 3 to swing, causing all the synchronous centering wheels 4 to press synchronously onto the cable. The peeling blade 2 is located outside the rotary cutting cylinder 1 and is directly or indirectly connected to the synchronous linkage positioning frame 3 of one set of synchronous linkage positioning components.

[0029] Combination Figures 1-7The synchronous linkage positioning frame 3 is rotatably connected to the inner wall of the rotary cutting cylinder 1. The synchronous linkage positioning frame 3 is provided with a centering wheel mounting hole 301 and a linkage mounting hole 302. The synchronous centering wheel 4 is rotatably connected in the centering wheel mounting hole 301. There are two linkage mounting holes 302. One end of the synchronous linkage rod 5 is rotatably connected to one of the linkage mounting holes 302 of the same group of synchronous linkage positioning frames 3. The other end of the synchronous linkage rod 5 is rotatably connected to one of the linkage mounting holes 302 of the adjacent group of synchronous linkage positioning frames 3. The positioning drive assembly is located on the outside of the rotary cutting cylinder 1. The positioning drive assembly includes a positioning drive screw 6, a transmission swing arm 7 and a rotating nut 8. One end of the transmission swing arm 7 is fixedly connected to the synchronous linkage positioning frame 3 of one group of synchronous linkage positioning assemblies. The other end of the transmission swing arm 7 is rotatably connected to the tail of the positioning drive screw 6. The rotating nut 8 is rotatably connected to the outer surface of the rotary cutting cylinder 1. The head of the positioning drive screw 6 is connected to the rotating nut 8 through a threaded structure. With the above structure, the cable to be circumcised is first passed through the inner cavity of the slicing cylinder 1. Then, the positioning drive screw 6 is rotated in the corresponding direction. The positioning drive screw 6 drives the transmission swing arm 7 to swing in the corresponding direction. The transmission swing arm 7 then transmits power to the corresponding synchronous linkage positioning frame 3, causing the synchronous linkage positioning frame 3 to rotate and bring the corresponding synchronous centering wheel 4 closer to the cable. At the same time, since there is a synchronous linkage rod 5 between adjacent synchronous linkage positioning frames 3, that is, all synchronous linkage positioning frames 3 are linked, so all synchronous centering wheels 4 will move synchronously towards the cable to achieve synchronous positioning. This ensures that the circular outline of the cable is accurately determined during the stripping process, thereby greatly improving the accuracy and consistency of the stripping path. At this time, the stripping blade 2 is also placed in a relatively ideal position along with one of the synchronous linkage positioning frames 3, waiting to start the circumcising.

[0030] Combination Figures 1-7 Two synchronous centering wheels 4 are provided in the same group, and the arrangement direction of the two synchronous centering wheels 4 is parallel to the axis of the rotary cutting cylinder 1. The axis of the synchronous centering wheels 4 is parallel to the axis of the rotary cutting cylinder 1. With the above structure, not only can the cable be accurately positioned, but the cable can also be straightened, making the rotary cutting operation smoother and more uniform.

[0031] Combination Figures 1-7The peeling mechanism further includes a pose adjustment mechanism for adjusting the relative pose of the peeling blade 2. This pose adjustment mechanism includes a first adjustment component and a second adjustment component. The first adjustment component is fixedly connected to the synchronous linkage positioning frame 3, and the second adjustment component is fixedly connected to the first adjustment component. The peeling blade 2 is fixedly mounted on the second adjustment component. The first adjustment component includes a first adjustment mounting base 9, an intermediate mounting block 10, an adjustment screw 11, and an adjustment nut 12. The first adjustment mounting base 9 is fixedly connected to the synchronous linkage positioning frame 3. One end of the intermediate mounting block 10 is rotatably connected to the first adjustment mounting base 9, and the other end of the intermediate mounting block 10 is rotatably connected to the tail of the adjustment screw 11. Next, the head of the adjusting screw 11 is connected to the adjusting nut 12 via a threaded structure, and the adjusting nut 12 is rotatably connected to the outer side of the rotary cutting cylinder 1; the second adjusting assembly includes a second adjusting mounting base 13, a sliding block 14, and a locking bolt 15. The second adjusting mounting base 13 is fixedly connected to the first adjusting mounting base 9. The second adjusting mounting base 13 is provided with a sliding groove. One end of the sliding block 14 is slidably connected in the sliding groove, and the other end of the sliding block 14 is fixedly connected to the peeling blade 2. The side wall of the second adjusting mounting base 13 is provided with an operation clearance window. The locking bolt 15 passes through the operation clearance window and is connected to the sliding block 14 located in the sliding groove to lock the sliding block 14.

[0032] With the above structure, after completing the positioning operation, observe whether the posture or angle of the stripper 2 is feasible. If adjustment is needed, rotate the adjusting screw 11 in the corresponding direction. The power is transmitted from the intermediate mounting block 10 to the first adjusting mounting seat 9, causing the first adjusting mounting seat 9 to rotate around its own rotation center to adjust the orientation (angle) of the stripper 2 to meet the current needs. Further, confirm the relative height difference between the stripper 2 and the cable, i.e., confirm the stripping depth. If the stripping depth needs adjustment, first loosen the locking bolt 15, then move the sliding block 14 in the corresponding direction until the stripper 2 is at the desired relative height. Finally, fix it with the locking bolt 15. In this way, the position and posture of the stripper 2 can be adjusted according to different cable sizes to obtain a more ideal circumferential cutting effect.

[0033] Combination Figures 1-7Along the axial direction of the rotary cutting cylinder 1, the cutting edge of the stripping blade 2 is inclined. This specially designed inclined blade structure allows for a smooth, arc-shaped transition in the cut surface when cutting the shielding layer, effectively controlling the surface roughness to below 7μm. Furthermore, the sloped fracture structure formed by the inclined blade facilitates subsequent processes such as insulation restoration and semi-conductive layer treatment, solving common industry pain points such as inaccurate stripping thickness control and uneven cross-sections in manual operations. It can automatically and efficiently produce smooth shielded fractures that meet high installation standards, improving overall cable installation quality and operational reliability.

[0034] Combination Figures 1-7 The rotary cutting drive mechanism includes a rotary cutting mounting base 16, a rotary cutting drive motor 17, and a rotary cutting transmission assembly. The rotary cutting mounting base 16 is fixedly connected to the housing of the rotary cutting drive motor 17.

With the above structure, under the drive of the rotary cutting drive motor 17, the rotary cutting cylinder 1 can rotate, thereby driving the peeling blade 2 to perform rotary cutting operations.

[0035] Combination Figures 1-2 and Figure 6 The traveling mechanism includes a traveling mounting housing 20, traveling rollers 21, a clamping drive mechanism, and a rolling drive mechanism. The traveling rollers 21 are disposed within the traveling mounting housing 20, and two sets of traveling rollers 21 are arranged vertically opposite each other. The clamping drive mechanism includes a clamping drive motor 22 and a clamping transmission assembly. The clamping drive motor 22 is fixedly disposed below the traveling mounting housing 20. The clamping transmission assembly includes a clamping gear transmission assembly and a clamping lead screw transmission assembly.

The clamping drive gear 23 is connected to the output shaft of the clamping drive motor 22, and the clamping driven gear 24... 4. Two sets are provided and respectively arranged on both sides of the clamping drive gear 23; the clamping screw transmission assembly is provided in two sets and is respectively located on both sides of the traveling roller 21. Each set of clamping screw transmission assembly includes a clamping transmission seat 25, a clamping transmission screw 26 and a clamping transmission screw nut 27. There are two clamping transmission seats 25 and two clamping transmission screw nuts 27 in the same set. The ends of the two sets of traveling rollers 21 are rotatably connected to the two clamping transmission seats 25. The clamping transmission screw 26 is a bidirectional screw. The two helical structures of the bidirectional screw with different directions of rotation are respectively engaged with the two clamping transmission screw nuts 27. The two clamping transmission screw nuts 27 are fixedly arranged on the two clamping transmission seats 25.

[0036] The rolling drive mechanism is provided in two sets and located on both sides of the clamping drive mechanism. Each set of rolling drive mechanism includes a rolling drive motor 28 and a rolling transmission assembly. The rolling drive motor 28 is indirectly mounted on one of the clamping transmission seats 25 in the same set. The rolling transmission assembly includes a right-angle transmission assembly 29 and a transmission shaft 30. The right-angle transmission assembly 29 is poweredly connected between the rolling drive motor 28 and the transmission shaft 30. The transmission shaft 30 is fixedly connected to the traveling roller 21.

[0037] With the above structure, after the cable passes between the two sets of traveling rollers 21, the clamping drive motor 22 is started to drive it. The clamping gear transmission assembly divides the power into two paths and transmits it to the two sets of clamping screw transmission assemblies, which drive the clamping transmission screws 26 of the two sets of clamping screw transmission assemblies to rotate. Then, the two clamping transmission seats 25 move towards each other until the two sets of rolling rollers clamp the cable. Then, the rolling drive motor 28 is started, and the right angle transmission assembly 29 and the transmission shaft 30 transmit the power to the traveling rollers 21, which drive the traveling rollers 21 to roll, thereby realizing the movement on the cable and continuously stripping the insulation shielding layer of the high-voltage cable with the stripping mechanism.

[0038] Example 2 Combination Figures 1-8 The automatic stripping method for high-voltage cable insulation shielding in this embodiment includes the following steps: (1) Pass the high-voltage cable through the walking roller 21 of the walking mechanism and the inner cavity of the rotary cutting cylinder 1 of the stripping mechanism, so that the whole device is mounted on the cable.

[0039] (2) The synchronous linkage positioning frame 3 of one set of synchronous linkage positioning components is driven to swing by the positioning drive component. The synchronous linkage rod 5 drives the other sets of synchronous linkage positioning frames 3 to swing synchronously, so that all synchronous centering wheels 4 press against the outer surface of the cable at the same time, realizing automatic centering of the device and the cable, ensuring that the rotary cutting cylinder 1 is coaxial with the cable, and the stripping blade 2 connected to the synchronous linkage positioning frame 3 swings to the initial cutting position together.

[0040] (3) The cutting angle and cutting depth of the stripper 2 are adjusted by the position adjustment mechanism. First, the tilt angle of the blade of the stripper 2 relative to the cable surface is adjusted, and then the stripping depth of the stripper 2 is adjusted.

[0041] (4) Start the clamping drive mechanism, drive the two sets of clamping screw drive components through the clamping transmission components, so that the upper and lower sets of traveling rollers 21 move towards each other and clamp on the cable surface, providing a stable clamping force for the device to move along the cable axis.

[0042] (5) Start the rolling drive mechanism and the rotary cutting drive mechanism. The rolling drive mechanism drives the traveling roller 21 to rotate so that the device moves at a constant speed along the cable axis. The rotary cutting drive mechanism drives the rotary cutting cylinder 1 to rotate and drive the stripping blade 2 to rotate and cut around the circumference of the cable. The spiral continuous stripping of the insulation shielding layer is achieved through the combined motion of axial movement and rotary cutting.

[0043] (6) When the device travels to the preset stripping length, the rolling drive mechanism and the rotary cutting drive mechanism are stopped, the reverse drive clamping drive mechanism is released from the traveling roller 21, and the reverse drive positioning drive component is used to make the synchronous centering wheel 4 disengage from the cable, and the device is removed from the cable to complete the stripping operation.

[0044] Furthermore, an integrated laser displacement sensor is used to collect length information in real time during the peeling process, and the measurement data is fed back to the PLC control system in real time. The drive motors of the walking component and the rotary cutting component are dynamically adjusted through a closed-loop control algorithm, thereby achieving high-precision control of the peeling length.

9. An automatic stripping method applied to the automatic stripping device for high-voltage cable insulation shielding as described in claim 8, characterized in that, Includes the following steps: (1) Pass the high-voltage cable through the traveling rollers of the traveling mechanism and the inner cavity of the peeling cylinder of the peeling mechanism, so that the whole device is mounted on the cable; (2) The synchronous linkage positioning frame of one group of synchronous linkage positioning components is driven to swing by the positioning drive component. The synchronous linkage rod drives the other groups of synchronous linkage positioning frames to swing synchronously, so that all synchronous centering wheels press against the outer surface of the cable at the same time, realizing the automatic centering of the device and the cable, ensuring that the rotary cutting cylinder is coaxial with the cable, and the stripping blade connected to the synchronous linkage positioning frame swings to the initial cutting position together. (3) The cutting angle and cutting depth of the stripper are adjusted by the position adjustment mechanism. First, the tilt angle of the stripper blade relative to the cable surface is adjusted, and then the stripping depth of the stripper is adjusted. (4) Start the clamping drive mechanism, drive the two sets of clamping screw drive components through the clamping transmission components, so that the upper and lower sets of traveling rollers move towards each other and clamp on the cable surface, providing a stable clamping force for the device to move along the cable axis; (5) Start the rolling drive mechanism and the rotary cutting drive mechanism. The rolling drive mechanism drives the traveling roller to rotate so that the device moves at a constant speed along the cable axis. The rotary cutting drive mechanism drives the rotary cutting cylinder to rotate and drives the stripping blade to rotate and cut around the circumference of the cable. The spiral continuous stripping of the insulation shielding layer is achieved through the combined motion of axial movement and rotary cutting. (6) When the device travels to the preset stripping length, stop the rolling drive mechanism and the rotary cutting drive mechanism, reverse drive the clamping drive mechanism to release the traveling roller, reverse drive the positioning drive assembly to make the synchronous centering wheel disengage from the cable, and remove the device from the cable to complete the stripping operation.
