Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown: An automatic control stripping device for live-line power distribution network operations includes a support frame 1 and a positioning frame 2. The support frame 1 and the positioning frame 2 are fixedly connected. A stripping mechanism 5 is rotatably connected to the top of the support frame 1. A conveying mechanism 3 is fixedly installed on the inner side of the positioning frame 2. Two sets of stripping mechanisms 5 are arranged symmetrically and alternately. Each stripping mechanism 5 includes a hollow frame 51. A stripping clamping block 54 is rotatably installed at the end of the hollow frame 51. An extension rod 6 is provided on the top of the support frame 1. An electric cylinder 8 is rotatably installed on the inner side of the extension rod 6. One piston rod of the electric cylinder 8... A guide frame 11 is fixedly connected to the end of the hollow frame 51. Horizontal connecting rods 10 are fixedly connected to both sides of the hollow frame 51. A second driven rod 12 is fixedly connected to the end of one of the horizontal connecting rods 10. A connecting block 13 is rotatably installed on one side edge of the second driven rod 12. The connecting block 13 is slidably connected to the guide frame 11. A T-shaped groove 14 is opened at the junction of the guide frame 11 and the connecting block 13. A cutting blade 9 is provided on the lower surface of the support frame 1. A first driven rod 4 is fixedly connected to the end of the other horizontal connecting rod 10. The end of the first driven rod 4 is rotatably connected to the support frame 1.
[0022] In this embodiment, the support frame 1 and the positioning frame 2 are fixedly connected to form a stable working foundation. The conveying mechanism 3 inside the positioning frame 2 is responsible for the precise conveying and positioning of the cable. The two sets of stripping mechanisms 5 arranged symmetrically at the top of the support frame 1 undertake the core stripping action. The hollow frame 51 of the stripping mechanism 5 provides an installation carrier for the internal components. The stripping clamping block 54 rotatably installed at its end is used to clamp the cable sheath. During operation, one end of the cable is first deployed inside the conveying mechanism 3, where it is clamped and fixed. Then, a notch is cut on the surface of the cable using a cutting blade 9. The stripping clamping block 54 of the subsequent stripping mechanism 5 clamps both sides of the notch, and then the electric cylinder 8 inside the extension rod 6 is activated. The electric cylinder 8 drives the guide frame 11 to move through the extension and retraction of the piston rod. The horizontal connecting rods 10 on both sides of the hollow frame 51 are respectively connected to the second driven rod 12 and the first driven rod 4. The end of the first driven rod 4 is rotatably connected to the support frame 1, providing support and limit for the rotation of the stripping mechanism 5. The connecting block 13 on the edge of the second driven rod 12 slides along the T-groove 14 of the guide frame 11, converting the linear motion of the electric cylinder 8 into the rotational motion of the stripping mechanism 5, thus removing the cable. The outer sheath is peeled off. During the peeling process, the conveying mechanism 3 slowly transports the cable to ensure that the peeling mechanism 5 can fully process the cable. After the operation is completed, the cable is removed, and the outer sheath initially deployed inside the conveying mechanism 3 is peeled off. During the peeling process, a set of peeling clamping blocks 54 is always kept in place to hold the cable sheath. Under the combined action of clamping force and cutting force, the cable sheath is peeled off smoothly. This coordinated operation can prevent displacement from affecting the peeling accuracy. The design of two sets of staggered and symmetrical peeling mechanisms 5 can ensure that the cable sheath is subjected to uniform force and prevent the cable core wire from being subjected to force. The stripping mechanism is designed to meet the stringent requirements for cable protection in live-line power distribution operations. It can also clamp cables. The cooperation between the horizontal connecting rod 10 and the first driven rod 4 provides stable support and rotation guidance for the stripping mechanism 5, further ensuring operational stability and significantly improving the stripping efficiency of live-line power distribution operations. It reduces manual intervention, lowers the labor intensity and safety risks for operators, and the coordinated work of all components forms a complete automated stripping process. This ensures consistent stripping quality and adapts to the special scenario requirements of live-line power distribution operations, providing a reliable guarantee for the efficient implementation of power distribution operations.
[0023] Example 2: According to Figure 3 , Figure 6 and Figure 7As shown, a servo motor 52 is fixedly installed on the top of the hollow frame 51. A push rod 56 is threadedly connected to the outer wall of the lead screw of the servo motor 52. The push rod 56 is slidably installed on the inner side of the hollow frame 51. A reinforcing auxiliary rod 55 is rotatably connected between the hollow frame 51 and the peeling clamping block 54. A bending rod 53 is rotatably installed at the corner of the hollow frame 51. One end of the bending rod 53 is rotatably connected to the peeling clamping block 54, and the other end of the bending rod 53 is rotatably connected to the push rod 56.
[0024] In this embodiment, when the servo motor 52 leadscrew rotates, the push rod 56, threadedly connected to the leadscrew, slides along the inner side of the hollow frame 51. The bent rod 53, rotatably installed at the corner of the hollow frame 51, converts the linear motion of the push rod 56 into clamping power. Its other end is rotatably connected to the peeling clamping block 54, pushing the peeling clamping block 54 to achieve opening and closing action. At the same time, the reinforcing auxiliary rod 55, rotatably connected between the hollow frame 51 and the peeling clamping block 54, plays a supporting and limiting role, ensuring stable and accurate clamping action. To meet the stripping needs of different cable specifications, the reinforced auxiliary rod 55 effectively improves the structural stability of the stripping clamping block 54, preventing deviation or shaking during clamping, ensuring that the cable sheath is firmly clamped without damaging the core wire. The hollow frame 51 provides a stable mounting carrier for each component, enabling the servo motor 52, push rod 56, bending rod 53, stripping clamping block 54, and reinforced auxiliary rod 55 to form a coordinated clamping mechanism, greatly improving the accuracy and reliability of stripping operations and meeting the stringent requirements of uninterrupted power distribution network operations.
[0025] Example 3: According to Figure 2 and Figure 4 As shown, the conveying mechanism 3 includes a motor drive assembly 31, which is provided in two sets, with each set containing two motor drive assemblies 31. One set of motor drive assemblies 31 is fixedly installed at the bottom of the positioning frame 2, and the other set of motor drive assemblies 31 is slidably installed at the top of the positioning frame 2 and is movably installed above the fixed set of motor drive assemblies 31. A limit block 33 is provided on the other side of the positioning frame 2. The output end of the motor drive assembly 31 is rotatably connected to the inside of the limit block 33. A roller 32 is fixedly installed at the output end of the motor drive assembly 31. The roller 32 is located inside the positioning frame 2. In use, the cable is clamped and conveyed by the two sets of rollers 32.
[0026] In this embodiment, the positioning frame 2 serves as the mounting base. The motor drive assembly 31 is divided into two groups, with two assemblies in each group. One group is fixedly installed at the bottom of the positioning frame 2, and the other group is slidably installed at the top of the positioning frame 2 and located above the fixed group. The limiting block 33 on the other side of the positioning frame 2 provides rotational support for the output end of the motor drive assembly 31, ensuring transmission stability. The roller 32 fixed at the output end of the motor drive assembly 31 is located inside the positioning frame 2. During operation, by adjusting the position of the top sliding group of the motor drive assembly 31, the upper and lower rollers 32 can accurately clamp the cable. After the motor drive assembly 31 starts, it drives the rollers 32 to rotate synchronously. The friction between the rollers 32 and the cable is used to achieve smooth cable transport. The two sets of motor drives... The vertical distribution and sliding design of component 31 allows for flexible adjustment of the distance between the two sets of rollers 32, adapting to cables of different diameters and specifications, thus offering strong versatility. The limiting block 33 provides limiting support for the output end of the motor drive component 31, effectively preventing deviation and shaking during transmission and ensuring conveying accuracy. The rollers 32 directly contact the cables and undertake the task of clamping and conveying. Their rotational power comes from the motor drive component 31, resulting in high transmission efficiency and stable conveying speed. This avoids jamming or displacement during cable conveying, providing precise positional assurance for subsequent stripping operations. No manual assistance is required to push the cables, reducing the manual labor intensity and safety risks of uninterrupted power distribution network operations, while improving operational efficiency and ensuring the automated and precise advancement of the overall stripping process.
[0027] Example 3: According to Figure 2 and Figure 4 As shown, a motor lead screw transmission assembly 34 is fixedly installed on one side of the positioning frame 2. A transmission frame 35 is threadedly connected to the outer wall of the lead screw of the motor lead screw transmission assembly 34. The transmission frame 35 is sleeved on the edge of the positioning frame 2. The transmission frame 35 is fixedly connected to the positioning plate of the movable motor transmission assembly 31. A strip hole 7 is opened inside the positioning frame 2. The output shaft of the movable motor transmission assembly 31 is located inside the strip hole 7.
[0028] In this embodiment, the motor lead screw transmission assembly 34 provides power. When its lead screw rotates, it drives the transmission frame 35, which is threaded to the outer wall, to move. The transmission frame 35 is sleeved on the edge of the positioning frame 2 and fixed to the positioning plate of the movable motor transmission assembly 31. At the same time, the output shaft of the movable motor transmission assembly 31 is located inside the strip hole 7 inside the positioning frame 2. Under the drive of the transmission frame 35, it slides along the strip hole 7 to realize the position adjustment of the movable motor transmission assembly 31, adapting to cables of different diameters. The strip hole 7 provides guidance for the output shaft of the movable motor transmission assembly 31, avoiding deviation during adjustment and improving the adaptability and accuracy of operation.
[0029] The usage and working principle of this device are as follows: First, deploy one end of the cable into the conveying mechanism 3 inside the positioning frame 2. Start the motor screw drive assembly 34 to drive the transmission frame 35. The transmission frame 35 drives the movable motor drive assembly 31 to slide along the strip hole 7 inside the positioning frame 2. Adjust the distance between the upper and lower sets of motor drive assemblies 31 so that the rollers 32 fixed at the output ends of the two sets of motor drive assemblies 31 clamp the cable. Then, the cutting blade 9 on the lower surface of the support frame 1 cuts a notch on the surface of the cable. Subsequently, start the servo motor 52 at the top of the hollow frame 51. The servo motor 52 screw rotates, driving the threaded push rod 56 to slide along the inside of the hollow frame 51. The push rod 56 pushes the stripping clamping block 54 to open and close through the bending rod 53, so that the stripping clamping block 54 clamps the two sides of the cable notch. The electric cylinder 8, which is rotatably mounted on the inner side of the extension rod 6, is activated. The piston rod of the electric cylinder 8 extends and retracts, driving the guide frame 11 to move. The connecting block 13 on the edge of the second driven rod 12 slides along the T-groove 14 of the guide frame 11, converting the linear motion of the electric cylinder 8 into the rotational motion of the stripping mechanism 5. The hollow frame 51 is connected to the second driven rod 12 and the first driven rod 4 respectively through the horizontal connecting rods 10 on both sides. The end of the first driven rod 4 is rotatably connected to the support frame 1, providing rotational support and limit for the stripping mechanism 5. The two sets of staggered and symmetrical stripping mechanisms 5 rotate together to strip the outer sheath of the cable. During the stripping process, the motor transmission component 31 of the conveying mechanism 3 drives the roller 32 to rotate synchronously, slowly conveying the cable. At the same time, a set of stripping clamping blocks 54 is always kept clamping the cable sheath until the cable is fully stripped.
