Description

Technical Field

[0001] This invention relates to the field of power distribution network construction, operation and maintenance, and in particular to an insulating encapsulation device. Background Technology

[0002] In the field of power distribution network construction, operation, and maintenance, live insulation retrofitting of bare conductors at 10kV and below is an important measure to improve power supply reliability and reduce line failure rates. With the continuous expansion of power distribution network scale and the increasing demand for insulation retrofitting, higher requirements are placed on the efficiency and quality of bare conductor insulation wrapping operations. Currently, bare conductor insulation wrapping is mostly completed manually, which has shortcomings such as low work efficiency, poor consistency in wrapping quality, and high safety risks for personnel working on live lines, making it difficult to meet the time and quality requirements of large-scale insulation retrofitting.

[0003] To replace manual operation, automated coating equipment has emerged in existing technologies, which uses a rotatable coating mechanism on the outside of the conductor to achieve spiral winding of the tape. However, in continuous coating operations, the synchronous stability of unwinding tension control and release film recovery in such equipment still struggles to meet the requirements of uniform coating layer and insulation reliability for long-distance coating. Specifically, fluctuations in unwinding tension can lead to uneven tape stretching or loose accumulation, directly affecting the density of the insulation layer; while mismatch between the release film recovery speed and the tape unwinding speed can cause release film stretching deformation or accumulation and jamming, thus interrupting continuous coating operations. These problems are particularly prominent in long-distance, continuous coating conditions, hindering the practical application and promotion of automated coating equipment. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is: the lack of synchronous stability of unwinding tension control and release film recycling in existing automated coating equipment during continuous coating operations.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes an insulating encapsulation device, which includes a frame unit and a clamping component that opens and closes to lock onto the object to be encapsulated; The covering unit includes a ring frame rotatably disposed on the outside of the clamping assembly, and a drive member for driving the ring frame to rotate; The unwinding unit includes a mounting base, an unwinding roller rotatably mounted on the mounting base, a guide rod mounted on the clamping assembly, and a magnetic assembly with the same polarity and facing each other, located between the mounting base and the unwinding roller. The recycling unit includes a take-up roller and a take-up assembly that is drively connected between the take-up roller and the clamping assembly, wherein the clamping assembly drives the take-up roller to rotate synchronously via the take-up assembly.

[0006] In a preferred embodiment of the insulating encapsulation device of the present invention: the magnetic component includes an unwinding base plate fixedly disposed at the upper end of the mounting base, an unwinding pressure plate fixedly disposed at the lower end of the unwinding roller, and permanent magnets respectively arrayed on the upper surface of the unwinding base plate and the lower surface of the unwinding pressure plate; The two sets of permanent magnets have the same polarity on their opposing surfaces and are evenly distributed in an array along the circumference of the unwinding base plate and the unwinding pressure plate.

[0007] In a preferred embodiment of the insulating encapsulation device of the present invention: a limiting pin is fixedly provided inside the mounting base; the unwinding roller is rotatably disposed at the end of the mounting base via the limiting pin; The unwinding pressure plate is coaxially fixed to the lower end of the unwinding roller and rotates synchronously with the unwinding roller; the unwinding base plate is coaxially fixed to the upper end of the mounting base; the limiting pin restricts the circumferential movement of the unwinding base plate.

[0008] In a preferred embodiment of the insulating encapsulation device of the present invention: the outer peripheral surface of the unwinding roller is provided with threads, and the roll body is pressed onto the threads by a nut.

[0009] In a preferred embodiment of the insulating encapsulation device of the present invention: a counter-magnetic component is further provided between the take-up roller and the take-up assembly, wherein the counter-magnetic components have the same polarity on their opposing surfaces.

[0010] In a preferred embodiment of the insulating encapsulation device of the present invention: the clamping component includes a fixed toothed ring and a movable toothed ring hinged to one side of the fixed toothed ring; the fixed toothed ring and the movable toothed ring can close to form a complete circular toothed ring.

[0011] In a preferred embodiment of the insulating encapsulation device of the present invention: the winding assembly includes a driven gear meshing with the outer side of the circular gear ring, and a connecting shaft fixedly disposed on the inner side of the winding roller; The rotation of the ring frame drives the take-up roller to rotate via the meshing transmission between the circular gear ring and the driven gear.

[0012] In a preferred embodiment of the insulating encapsulation device of the present invention: the encapsulation unit further includes an adjustment component, the adjustment component including a mounting plate fixedly disposed on the upper end of the annular frame, a pressure roller damped and hinged to one side of the mounting plate, and a guide plate disposed at the bottom of the pressure roller.

[0013] In a preferred embodiment of the insulating encapsulation device of the present invention: it further includes a cutting unit, the cutting unit including a mounting frame fixedly disposed on the upper end of the ring frame, a movable component disposed on the inner side of the mounting frame, a guide post fixedly disposed on one side of the mounting frame, and a cutting wheel fixedly disposed on one side of the movable component; The moving component drives the cutting wheel to feed along the width direction of the strip.

[0014] In a preferred embodiment of the insulating encapsulation device of the present invention, a walking unit is further included. The walking unit includes a frame, fixed seats respectively fixed at both ends of the frame, walking rollers fixed on the mounting seats, and a mobile motor for driving the walking rollers to rotate.

[0015] The beneficial effects of this invention are as follows: by setting up magnetic components of the same polarity and arranged oppositely between the mounting base and the unwinding roller, non-contact magnetic damping is formed using the principle of like poles repulsion, applying a reverse damping force to the unwinding roller, thus maintaining a constant tension during the unwinding process. This ensures stable unwinding tension throughout long-term continuous coating operations, significantly improving the uniformity and insulation reliability of the coating layer. The tightening component is driven between the take-up roller and the clamping component, allowing the rotation of the take-up roller to directly originate from the rotating main shaft of the clamping component. This ensures that the release film winding speed adapts to the tape unwinding speed, preventing release film accumulation or stretching due to speed mismatch during instantaneous start-stop and acceleration / deceleration conditions. The clamping component functions as both an opening / closing locking mechanism and a rotating drive shaft, with the opening / closing and rotating actions completely decoupled and independent, simplifying the overall machine structure. Opposing magnetic components are also provided between the take-up roller and the tightening component to prevent the release film from stretching, thinning, or accumulating and wrinkling during the winding process.

Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-3 This embodiment provides an insulating encapsulation device, including a frame unit 1 and a clamping component 11 that opens and closes to lock onto the object to be encapsulated; The covering unit 2 includes an annular frame 21 rotatably disposed on the outside of the clamping assembly 11, and a driving member 22 for driving the annular frame 21 to rotate. The unwinding unit 3 includes a mounting base 31, an unwinding roller 32 rotatably mounted on the mounting base 31, a guide rod 33 mounted on the clamping assembly 11, and a magnetic assembly 34 with the same polarity and facing each other, located between the mounting base 31 and the unwinding roller 32. The recycling unit 4 includes a take-up roller 41 and a take-up assembly 42 that is driven between the take-up roller 41 and the clamping assembly 11. The clamping assembly 11 drives the take-up roller 41 to rotate synchronously via the take-up assembly 42.

[0020] This embodiment provides an insulation encapsulation device suitable for live-line insulation work on bare conductors in 10kV and below power distribution networks. The entire machine weighs no more than 3kg and can be mounted on the bare conductor via an insulated operating rod, an insulated bucket truck operating arm, or a drone for operation. The entire machine moves axially back and forth on any length of bare conductor from 0 to 10 meters, completing a 360° spiral wrapping with each reciprocation. The overlap rate, thickness uniformity, and insulation purity of the wrapping layer all meet the requirements for live-line work. The clamping component 11 is configured as an openable and closable annular clamping structure. After the entire machine reaches the working position, the operator controls the insulated operating rod to open the annular clamping structure, insert the bare conductor to be wrapped, and then close and lock it, so that the clamping component 11 is coaxially positioned with the bare conductor. After closing, the clamping component 11 not only performs the function of coaxial clamping and positioning of the bare conductor during the entire wrapping operation, but also serves as the power rotation spindle for the rotational wrapping action of the entire machine. That is, the two functions of "opening and locking" and "drive spindle" are performed by the same clamping component 11. The coaxial positioning and rotational wrapping action of the clamping component 11 on the bare conductor are completed by switching between two states of the same component. There is no mechanical interference between the opening and closing action and the rotation action, and they are completely decoupled in terms of timing.

[0021] Preferably, the ring frame 21 is rotatably disposed on the outside of the clamping assembly 11 and is driven by the drive member 22 to rotate around the axis of the clamping assembly 11. The rotation of the ring frame 21 causes the thermoplastic insulating tape loaded on the unwinding roller 32 to spirally wrap around the bare conductor 360°.

[0022] Preferably, the drive unit 22 can be a servo motor remotely controlled by an insulated operating lever, a hydraulic drive for an insulated bucket truck, or a geared motor mounted on a drone. Any drive source only needs to drive the ring frame 21 to rotate, without needing to independently drive the take-up roller 41 or the opening and closing mechanism.

[0023] Preferably, the mounting base 31 is fixed on the annular frame 21, and the unwinding roller 32 is rotatably mounted on the mounting base 31. The guide rod 33 is mounted on the clamping assembly 11 and guides the thermoplastic insulating tape from the unwinding roller 32 to the wrapping station. Since the clamping assembly 11 remains stationary and coaxially positioned with the bare wire during the rotational wrapping process and does not rotate with the annular frame 21, while the unwinding roller 32 rotates with the annular frame 21, the tape is released from the unwinding roller 32, changes direction after passing through the guide rod 33, and is then pressed onto the bare wire. There is no relative sliding between the unwinding roller 32 and the guide rod 33, or between the unwinding path and the bare wire caused by rotation.

[0024] A magnetic assembly 34 with the same polarity and facing each other is provided between the mounting base 31 and the unwinding roller 32. The two sets of magnetic components of the magnetic assembly 34 form a non-contact magnetic damping within a gap of 1~3mm. Utilizing the principle of like poles repulsion, the magnetic damping applies a constant, gentle, and unchanging reverse damping force to the unwinding roller 32, maintaining a constant tension during the unwinding process. The non-contact magnetic damping eliminates mechanical contact, metal fatigue, and wear particles, reducing the fluctuation range of the unwinding tension over any length of 0~10 meters, and extending the lifespan of the damping structure.

[0025] Preferably, the take-up roller 41 is rotatably mounted on the annular frame 21 for retrieving the release film from the back side of the thermoplastic insulating tape. The take-up assembly 42 is driven between the take-up roller 41 and the clamping assembly 11; as the annular frame 21 rotates around the clamping assembly 11, the rotation of the clamping assembly 11 is transmitted to the take-up roller 41 via the take-up assembly 42, causing the take-up roller 41 to rotate synchronously with the clamping assembly 11, that is, the rotation of the take-up roller 41 comes directly from the rotating main shaft of the clamping assembly 11 itself. The release film take-up speed and the tape unwinding speed are matched at the same source at the transmission chain level, originating from the rotation of the clamping assembly 11, and are completely decoupled from software speed regulation. The matching accuracy of the take-up speed and unwinding speed is determined only by the mechanical accuracy of the transmission chain, and is no longer affected by the 0.1~0.5 second lag of the software speed regulation closed loop.

[0026] Working process: After the machine reaches the working position, the clamping assembly 11 opens and fits the bare wire, then closes and locks. The drive unit 22 drives the ring frame 21 to rotate around the axis of the clamping assembly 11; the unwinding roller 32 feeds out the tape under the constant damping of the magnetic component 34; the guide rod 33 is set on the clamping assembly 11 and remains stationary, guiding the tape to the surface of the bare wire; each time the ring frame 21 rotates, the tape spirally wraps around the bare wire once; at the same time, the winding assembly 42 drives the winding roller 41 to rotate synchronously through the rotation of the clamping assembly 11, and the release film is synchronously recovered at the peeling point.

[0027] With the above configuration, the insulation encapsulation device of this embodiment can continuously spirally wrap thermoplastic insulating tape along the bare conductor 360° under live working conditions. Furthermore, non-contact magnetic damping is formed by the magnetic components 34 with the same polarity and facing each other between the mounting base 31 and the unwinding roller 32. By utilizing the principle of like poles repulsion, a constant repulsive force field that does not change with the rotation speed is formed between the two opposing surfaces, so that the unwinding tension remains stable under the continuous vibration condition of live working. Secondly, the winding assembly 42 is connected to the winding roller 41 and the clamping assembly 11 through a transmission, so that the rotation of the winding roller 41 comes directly from the rotating main shaft of the clamping assembly 11 itself, forming a speed matching at the transmission chain level and completely decoupling from the software speed regulation. The release film winding speed and the tape unwinding speed are naturally aligned at the mechanical transmission chain level, and there will never be an instantaneous mismatch caused by "software speed regulation lag". In the instantaneous start-stop and acceleration / deceleration scenarios under live operation, the inherent response speed of the mechanical transmission is much faster than the software closed loop, and the winding action and the unwinding action follow synchronously on the time scale.

[0028] Reference Figures 1-3 In one embodiment of the present invention, the magnetic component 34 includes an unwinding base plate 341 fixedly disposed on the upper end of the mounting base 31, an unwinding pressure plate 342 fixedly disposed on the lower end of the unwinding roller 32, and permanent magnets 343 respectively arrayed on the upper end surface of the unwinding base plate 341 and the lower end surface of the unwinding pressure plate 342. The two sets of permanent magnets 343 have the same polarity on their opposing surfaces and are evenly distributed in an array along the circumference of the unwinding base plate 341 and the unwinding pressure plate 342.

[0029] Furthermore, a limiting pin 311 is fixedly and through the interior of the mounting base 31; the unwinding roller 32 is rotatably mounted on the end of the mounting base 31 via the limiting pin 311. The unwinding pressure plate 342 is coaxially fixed to the lower end of the unwinding roller 32 and rotates synchronously with the unwinding roller 32; the unwinding base plate 341 is coaxially fixed to the upper end of the mounting base 31; the limiting pin 311 restricts the circumferential movement of the unwinding base plate 341.

[0030] Furthermore, the outer circumferential surface of the unwinding roller 32 is provided with a thread 321, and the roll body is pressed onto the thread 321 by a nut 322.

[0031] Furthermore, a counter magnetic component 43 is provided between the take-up roller 41 and the take-up assembly 42, and the counter magnetic components 43 have the same polarity on their opposing surfaces.

[0032] Furthermore, the engaging component 11 includes a fixed toothed ring 111 and a movable toothed ring 112 hinged to one side of the fixed toothed ring 111; the fixed toothed ring 111 and the movable toothed ring 112 can be closed to form a complete circular toothed ring 12.

[0033] Furthermore, the winding assembly 42 includes a driven gear 421 meshing with the outer side of the full circular gear ring 12, and a connecting shaft 422 fixedly disposed on the inner side of the winding roller 41. The rotation of the ring frame 21 drives the take-up roller 41 to rotate through the meshing transmission of the full circular gear ring 12 and the driven gear 421.

[0034] In this embodiment, the magnetic component 34 is composed of a three-layer plate array structure, specifically including an unwinding base plate 341, an unwinding pressure plate 342, and permanent magnets 343. The unwinding base plate 341 is fixedly disposed at the upper end of the mounting base 31, its center is concentric with the axis of the unwinding roller 32, and its outer diameter is slightly smaller than the radius of the unwinding roller 32; the unwinding pressure plate 342 is fixedly disposed at the lower end of the unwinding roller 32, its center is concentric with the axis of the unwinding roller 32, and its outer diameter is the same as that of the unwinding base plate 341; the permanent magnets 343 are respectively arrayed and embedded in the upper end surface of the unwinding base plate 341 and the lower end surface of the unwinding pressure plate 342, with each group of permanent magnets 343... Multiple fan-shaped or rectangular permanent magnets are uniformly arranged in an array along the circumference of the unwinding base plate 341 and the unwinding pressure plate 342, with equidistant air gaps between adjacent permanent magnets; the opposing surfaces of the two sets of permanent magnets 343 have the same polarity, that is, if the upper end face of the permanent magnet on the unwinding base plate 341 is the N pole, then the lower end face of the permanent magnet on the unwinding pressure plate 342 at the directly opposite position is also the N pole; the two sets of permanent magnets 343 are uniformly distributed in an array along the circumference of the unwinding base plate 341 and the unwinding pressure plate 342.

[0035] When the unwinding roller 32 rotates and drives the unwinding pressure plate 342 to rotate synchronously, the permanent magnets 343 on the unwinding pressure plate 342 sweep circumferentially below the permanent magnets 343 on the unwinding base plate 341. The opposing surfaces of the two sets of permanent magnets 343 always maintain a repulsive relationship with the same polarity. The magnetic lines of force pass through the tiny air gap between the two plates to form a constant repulsive force field. This repulsive force field acts on the unwinding pressure plate 342 in a direction perpendicular to the plate surface, forming a reverse damping torque against the rotation direction of the unwinding roller 32. Since the polarity combination of each pair of permanent magnets 343 at any circumferential position maintains the same repulsive relationship of "N to N" or "S to S", the magnitude of the repulsive force does not change with the rotation angle of the unwinding roller 32, forming a constant, gentle, and unchanging reverse damping force, so that the unwinding tension remains stable during long continuous wrapping.

[0036] Preferably, a vertical limiting pin 311 is fixedly installed inside the mounting base 31, with its lower end fixed to the bottom of the mounting base 31 and its upper end extending upwards. The unwinding roller 32 is rotatably mounted on the end of the mounting base 31 via the limiting pin 311. Specifically, the central shaft hole of the unwinding roller 32 is fitted onto the limiting pin 311, and circumferential rotation is achieved through a bearing. The unwinding pressure plate 342 is coaxially fixed to the lower end of the unwinding roller 32 and rotates synchronously with the unwinding roller 32. The unwinding base plate 341 is coaxially fixed to the upper end of the mounting base 31, and a non-circular through hole is provided in its center. The cross-sectional shape of the limiting pin 311 matches the hole, and the circumferential movement of the unwinding base plate 341 is restricted by the limiting pin 311. The unwinding base plate 341 must remain absolutely stationary, and the position of the permanent magnet array 343 on it cannot rotate; otherwise, the circumferential uniform array distribution characteristics of the magnetic components 34 will be destroyed, and the constancy of the damping force will fail.

[0037] When the unwinding roller 32 rotates, the unwinding pressure plate 342 rotates synchronously, but the unwinding base plate 341 is fixed to the mounting base 31 through the limiting shaft pin 311 and remains stationary. A relative motion relationship of "static on top and moving on the bottom" is formed between the unwinding pressure plate 342 and the unwinding base plate 341. The permanent magnet 343 on the unwinding pressure plate 342 passes circumferentially directly below the permanent magnet 343 on the stationary unwinding base plate 341, maintaining non-contact magnetic damping.

[0038] Preferably, the outer circumferential surface of the unwinding roller 32 is provided with an external thread 321, which extends axially along the unwinding roller 32 and covers the entire outer circumferential surface. The roll of thermoplastic insulating tape loaded on the unwinding roller 32 is pressed onto the thread 321 by a nut 322. Specifically, after the center hole of the tape roll is fitted onto the unwinding roller 32, the lower end face of the tape roll is pressed against the unwinding pressure plate 342 located below the tape roll. The nut 322 is screwed into the external thread 321 from the upper end of the unwinding roller 32 to press the upper end face of the tape roll and prevent the tape roll from axially shifting during the unwinding process.

[0039] When the unwinding roller 32 rotates, the tape roll rotates synchronously with the unwinding roller 32 and maintains a stable axial position under the axial locking of the thread 321 and the nut 322. The tape is released tangentially from the outer circumference of the tape roll and guided to the wrapping station by the guide rod 33. The threaded locking structure prevents the tape roll from experiencing the triple failure of "axial movement - wrinkling - breakage" during the unwinding process.

[0040] Similarly, a counter-magnetic assembly 43 is provided between the take-up roller 41 and the take-up assembly 42. Its structure is similar to that of the magnetic assembly 34 in the unwinding unit 3. It includes a first magnetic plate located at the lower end of the take-up roller 41 and a second magnetic plate located at the upper end of the take-up assembly 42. Permanent magnets with the same polarity are arranged in an array on the two plates respectively. The counter-magnetic assemblies 43 have the same polarity on their counter-facing surfaces and are evenly distributed in an array along the circumference of the take-up roller 41 and the take-up assembly 42 to provide non-contact magnetic damping when the take-up roller 41 is winding.

[0041] When the take-up roller 41 rotates and recycles the release film under the drive of the take-up assembly 42, the opposing magnetic assembly 43 forms the same non-contact magnetic damping between the take-up roller 41 and the take-up assembly 42 as the unwinding side, so that the take-up roller 41 maintains constant tension during the take-up of the release film and avoids the release film from stretching and thinning or accumulating and wrinkling during the take-up process. It forms a double-ended closed loop of "unwinding constant tension + take-up constant tension" with the unwinding side magnetic assembly 34.

[0042] Preferably, the engaging component 11 specifically includes a fixed gear ring 111 and a movable gear ring 112; the fixed gear ring 111 occupies the main part of the whole circular gear ring 12 and is fixedly installed on the body of the engaging component 11; the movable gear ring 112 occupies the remaining part of the whole circular gear ring 12 and is hinged to one side of the fixed gear ring 111 through a hinge structure. The movable gear ring 112 can swing relative to the fixed gear ring 111 around the hinge axis to open or close; the fixed gear ring 111 and the movable gear ring 112 can close to form the whole circular gear ring 12. After closing, the teeth of the two are aligned and meshed on the whole circumference, and the outer circumferential surface forms a complete outer gear ring.

[0043] After the machine reaches the working position, the movable gear ring 112 swings open to fit the bare wire, and then swings in the opposite direction to close and lock. The closed circular gear ring 12 not only serves as a coaxial clamping and positioning function for the bare wire, but also as the transmission main shaft of the winding assembly 42. The outer teeth of the circular gear ring 12 are the gear ring reference for the meshing transmission of the driven gear 421 in the winding assembly 42.

[0044] The take-up assembly 42 specifically includes a driven gear 421 and a connecting shaft 422. The driven gear 421 meshes with the outer side of the full circular gear ring 12, and its number of teeth matches the number of teeth of the full circular gear ring 12 according to a preset transmission ratio. When the ring frame 21 revolves around the clamping assembly 11 once, the driven gear 421 rotates several times relative to the full circular gear ring 12. The specific number of rotations is determined by the tooth ratio. The connecting shaft 422 is fixedly installed on the inner side of the take-up roller 41, with one end fixed to the hub of the driven gear 421 and the other end fixed to the center of the take-up roller 41. Its working principle is as follows: the driving component 22 drives the ring frame 21 to rotate around the axis of the clamping assembly 11; the driven gear 421 is mounted on the winding assembly 42 and revolves around the axis of the clamping assembly 11 together with the ring frame 21; at the same time, since the driven gear 421 meshes with the outer teeth of the full circular gear ring 12 and the full circular gear ring 12 is stationary, the driven gear 421 rotates relative to the full circular gear ring 12 during the revolution; the rotation of the driven gear 421 is transmitted to the winding roller 41 through the connecting shaft 422, and the rotation speed of the winding roller 41 and the rotation speed of the ring frame 21 form a fixed transmission ratio relationship, and the release film winding speed is adapted to the tape unwinding speed.

[0045] Reference Figure 4In one embodiment of the present invention, the covering unit 2 further includes an adjustment component 23, which includes a mounting plate 231 fixedly disposed on the upper end of the ring frame 21, a pressure roller 232 damped and hinged to one side of the mounting plate 231, and a guide plate 233 disposed at the bottom of the pressure roller 232.

[0046] In this embodiment, the adjustment component 23 is disposed on the coating unit 2, located between the unwinding unit 3 and the coating station, and is used to provide stable clamping force and guidance for the released tape. Mounting plate 231 is fixedly installed at the upper end of ring frame 21. Mounting plate 231 is located near the coating station and adjacent to the downstream end of guide rod 33. The surface of mounting plate 231 is parallel to the direction of belt movement. Pressing roller 232 is hinged to one side of mounting plate 231. Pressing roller 232 is hinged to the lower side wall of mounting plate 231 through a damping hinge (the hinge has a built-in damping element such as a torsion spring). The hinge axis is perpendicular to the direction of belt movement. Pressing roller 232 can swing freely around the hinge axis in the direction of gravity and is buffered by the damping element. Guide plate 233 is fixedly installed at the bottom of pressing roller 232. The upper end surface of guide plate 233 and the lower generatrix of pressing roller 232 form a guide channel extending along the direction of belt movement. Its surface is at a predetermined angle to the direction of belt movement (used to change the direction of belt movement in advance before the belt enters the coating station).

[0047] After being guided by the guide rod 33 from the unwinding roller 32, the tape enters the guide channel of the adjusting assembly 23. Under the combined action of the damping hinge, the clamping roller 232 naturally presses against the end face of the guide plate 233, forming a stable clamping force on the tape sandwiched between them. Due to the buffering characteristics of the damping hinge, the clamping roller 232 automatically presses down to compensate when the clamping force is too low, and buffers and lifts up to avoid pressure when the clamping force is too high, forming an "adaptive clamping" mechanism to eliminate slippage, wrinkles, and serpentine deviation of the tape during unwinding and wrapping. The guide plate 233 performs a secondary pre-bending of the tape below the clamping roller 232, changing the direction angle of movement of the tape when it enters the wrapping station, so that it adheres to the bare conductor at a predetermined helical angle.

[0048] Reference Figure 5 In one embodiment of the present invention, a cutting unit 5 is also included. The cutting unit 5 includes a mounting frame 51 fixedly disposed on the upper end of the ring frame 21, a moving component 52 disposed on the inner side of the mounting frame 51, a guide post 53 fixedly disposed on one side of the mounting frame 51, and a cutting wheel 54 fixedly disposed on one side of the moving component 52. The moving component 52 drives the cutting wheel 54 to feed along the width direction of the strip.

[0049] In this embodiment, the cutting unit 5 is located downstream of the coating station and is used to cut the tape in the width direction after coating is completed. Specifically, the cutting unit 5 includes a mounting frame 51, a moving component 52, a guide post 53, and a cutting wheel 54. The mounting frame 51 is fixedly mounted on the upper end of the ring frame 21, located a certain distance downstream of the coating station, and has a rectangular frame structure with an inner cavity. The moving component 52 is located inside the mounting frame 51, slidingly engaging with the inner cavity of the mounting frame 51, and can slide horizontally along the width direction of the tape. The guide post 53 is fixedly mounted on one side of the mounting frame 51, with its axis extending horizontally along the width direction of the tape, and its two ends fixed to the two ends of the mounting frame 51, providing a precise guiding reference for the sliding of the moving component 52. The cutting wheel 54 is fixedly mounted on one side of the moving component 52, with a blade-shaped rim, its rotating surface parallel to the width direction of the tape, and its axis perpendicular to the direction of tape movement.

[0050] Preferably, the moving component 52 slides horizontally along the width direction of the strip, and the sliding power is provided by a pneumatic or electric push rod or gear; Figure 5 The moving component 52 is driven by a servo motor to rotate a gear, which in turn causes a rack meshing with the gear to drive the cutting wheel 54 to slide horizontally along the width of the strip for cutting.

[0051] After the coating station completes a continuous spiral coating of a certain length, the cutting unit 5 is started. The moving component 52 drives the cutting wheel 54 to feed horizontally along the direction of the guide column 53 (i.e. the width direction of the strip). The blade of the cutting wheel 54 cuts from one side along the width direction of the tape, penetrates the width of the tape, and cuts off a narrow strip of tape that matches the diameter of the bare wire, realizing "cutting the width as needed". This avoids the waste caused by cutting off the entire tape and at the same time makes the cutting edge naturally aligned with the end face of the coating layer, improving the neatness of the coating layer.

[0052] Reference Figures 1-6 In one embodiment of the present invention, a walking unit 6 is also included. The walking unit 6 includes a frame 61, fixed seats 62 respectively fixed at both ends of the frame 61, walking rollers 63 fixedly mounted on the mounting base, and a mobile motor 64 for driving the walking rollers 63 to rotate.

[0053] In this embodiment, the walking unit 6 is located at the bottom of the machine and is used to drive the machine to continuously advance along the direction of the bare conductor. The frame 61 is fixedly located at the bottom of the machine and serves as the connecting base between the walking unit 6 and the covering unit 2. Each end of the frame 61 has a mounting seat 62. The mounting seats 62 are fixedly located at both ends of the frame 61, below the left and right ends of the frame 61, with their upper ends fixed to the frame 61 and their lower ends extending downwards. The walking rollers 63 are fixedly located on the mounting seats 62. The walking rollers 63 are rotatably mounted on the lower end of the mounting seats 62 through bearings, and their wheel surfaces are in contact with the surface of the bare conductor. The moving motor 64 is used to drive the walking rollers 63 to rotate. The moving motor 64 is located on one side of the frame 61, and its output shaft is connected to the central shaft of the walking rollers 63 through a reduction mechanism.

[0054] When the walking unit 6 is started, the moving motor 64 drives the walking roller 63 to rotate through the reduction mechanism. The walking roller 63 rolls axially on the surface of the bare conductor, driving the whole machine to move smoothly along the direction of the bare conductor. This, in conjunction with the rotary wrapping of the ring frame 21 in the wrapping unit 2, forms a dual-axis linkage wrapping mode of "rotary wrapping + axial propulsion", enabling the whole machine to move continuously at a constant speed on the bare conductor and continuously complete the spiral wrapping operation of long sections of bare conductor.

[0055] The overall operation of this device is as follows: The entire device is secured to the head of the insulated operating rod, the end effector of the insulated bucket truck operating arm, or the lower attachment point of the UAV mounting platform using special clips. The operator lifts the clamping assembly 11 to the coaxial height of the bare conductor to be covered; during lifting, the open end of the clamping assembly 11 should face the axis of the bare conductor. The operator inserts the open end of the clamping assembly 11 into the bare conductor; the bare conductor passes through the central hole of the clamping assembly 11, and the fixed toothed ring 111 of the clamping assembly 11 is coaxially aligned with the bare conductor. The operator causes the movable toothed ring 112 to swing in the opposite direction and close, aligning and engaging the teeth of the fixed toothed ring 111 and the movable toothed ring 112 around the entire circumference, closing to form a complete circular toothed ring 12, which is locked onto the bare conductor. When the drive unit 22 is powered on, it starts to drive the ring frame 21 to rotate around the axis of the clamping assembly 11. The unwinding roller 32 revolves with the ring frame 21 and rotates around the axis of the bare conductor. At the same time, the magnetic component 34 (located between the mounting base 31 and the unwinding roller 32, with the same polarity and facing each other) forms a non-contact magnetic damping between the unwinding roller 32 and the mounting base 31 through the principle of like poles repulsion, applying a constant, gentle, and unchanging reverse damping force to the unwinding roller 32. The damping force keeps the unwinding tension stable throughout the long continuous wrapping, and the tape is smoothly released tangentially from the surface of the unwinding roller 32. After the tape is released from the rotating unwinding roller 32, it changes direction of movement by the stationary guide rod 33 and aligns with the surface of the bare conductor. Since the guide rod 33 is located on the stationary clamping assembly 11 and the unwinding roller 32 is located on the rotating ring frame 21, the tape rotates and wraps around the periphery of the conductor.

[0056] Secondly, the tape enters the guide channel of the adjusting component 23. Under the combined action of its own weight and the damping hinge, the clamping roller 232 naturally presses against the upper surface of the guide plate 233, forming a stable clamping force on the tape sandwiched between the two. The damping hinge has a buffering characteristic. When the clamping force is too low, the clamping roller 232 automatically presses down to compensate. When the clamping force is too high, the clamping roller 232 buffers and lifts up to avoid it, forming an adaptive clamping mechanism to eliminate slippage, wrinkles and serpentine deviation of the tape during unwinding and wrapping. The guide plate 233 performs a secondary pre-bending of the tape below the clamping roller 232, changes the direction angle of movement of the tape when it enters the wrapping station, and makes it adhere to the bare wire with a predetermined helical angle. The tape is attached to the surface of the bare conductor under the guidance of the guide rod 33 and the pressure of the adjusting component 23; the tape spirals around the bare conductor once every time the ring frame 21 rotates; the clamping component 11 remains coaxial and stationary with the bare conductor in the closed and locked state. The dual function of the clamping component 11 (opening and closing locking + transmission main shaft) completely decouples the opening and closing action from the rotation action in terms of timing and prevents them from interfering with each other. A release film is attached to the back side of the thermoplastic insulating tape. The release film is peeled off the moment the tape is attached to the bare wire. The rotation of the clamping assembly 11 is transmitted to the take-up roller 41 via the take-up assembly 42, so that the take-up roller 41 rotates synchronously with the clamping assembly 11. The release film is synchronously recovered by the take-up roller 41 at the peeling point. The magnetic assembly 43 at the bottom of the take-up roller 41 (with the same polarity on the opposite side) provides the same non-contact magnetic damping as the unwinding side, so that the take-up roller 41 maintains constant tension when winding the release film. The speeds of the take-up roller 41 and the unwinding roller 32 are naturally aligned at the transmission chain level, forming a speed matching, and are completely decoupled from software speed regulation.

[0057] After completing a continuous spiral wrapping of a certain length, the cutting unit 5 is activated, and the moving component 52 slides horizontally along the direction of the guide post 53 (the width direction of the strip) to drive the cutting wheel 54 to feed. The blade of the cutting wheel 54 cuts into the tape from one side, penetrates the width of the tape, and cuts off a narrow strip of tape that matches the diameter of the bare wire, so as to achieve cutting to the required width and avoid waste caused by cutting off the entire tape.

[0058] When the moving motor 64 of the walking unit 6 is powered on, it drives the walking roller 63 to roll axially on the surface of the bare conductor. The rolling of the walking roller 63 drives the whole machine to move smoothly along the direction of the bare conductor. In conjunction with the rotary wrapping of the ring frame 21, a dual-axis linkage wrapping mode of "rotary wrapping + axial propulsion" is formed. This allows the whole machine to move continuously at a constant speed on the bare conductor and continuously complete the spiral wrapping operation of long sections of bare conductor.

[0059] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
