Description

Technical Field

[0001] This invention relates to the field of cable construction and maintenance equipment technology, and more specifically, to an automated cable sheath processing device. Background Technology

[0002] In power systems, the fabrication and installation of accessories for 110kV and above high-voltage cables are crucial for ensuring the reliable operation of transmission lines. Among these processes, the stripping and cleaning of the cable sheath—removing the outer sheath, metal sheath, and semiconductor layer, and cleaning the exposed cable insulation surface of asphalt and other adhering substances—directly affects the insulation performance and long-term operational reliability of the cable accessory interfaces. Currently, traditional cable sheath treatment methods heavily rely on manual labor using hand tools such as glass slides, planers, and files for layer-by-layer peeling and polishing. This traditional method has many drawbacks: First, it is extremely inefficient, with slow manual peeling speed and high labor intensity, severely hindering project progress. Second, the quality of treatment heavily depends on the operator's personal skills and experience; the cutting depth is difficult to control precisely, easily damaging the cable insulation layer or leaving scratches on the insulation surface, creating localized electric field concentration points and posing safety hazards for subsequent operation. Third, manual operation is unsafe, especially when peeling off hard metal sheaths, where operators are prone to injury. Furthermore, for residual asphalt on the cable insulation surface, manual cleaning typically involves repeated wiping with a hot air gun, cotton cloth, and cleaning agent; this process is cumbersome, inconsistent cleanliness is difficult to guarantee, and it also poses environmental pollution and health risks to operators. To address the pain points of manual processing, some automatic or semi-automatic mechanical tools have appeared on the market. However, these existing tools generally suffer from limited efficiency improvements. More importantly, they are expensive, have limited adaptability to cable specifications, and are unable to flexibly handle cables of different diameters and thicknesses on site. They are also often bulky and complex in structure, with stringent requirements for the work site and environment, making them unsuitable for flexible movement and deployment in narrow cable trenches, tunnels, or outdoor conditions. Especially when dealing with the large-diameter, high-hardness cable sheaths commonly found in 110kV and above cables, the cutting power, clamping driving force, and precise control capabilities of existing devices are all insufficient. Therefore, how to provide an automated sheathing treatment device that can improve operational efficiency and processing accuracy, while optimizing usage conditions, reducing device size, lowering the operating threshold, and being widely adaptable to various specifications of cables, including large-diameter and high-hardness cables, has become a technical problem to be solved in this field.

[0025] Furthermore, the second moving module 26 includes: a first clamping member 261 for clamping and abutting one side of the cable 5 and a second clamping member 262 corresponding to the first clamping member 261 for clamping and abutting the other side of the cable 5; the first clamping member 261 is detachably connected to the fixing frame 21, and the second clamping member 262 is detachably connected to the device base 1, and the first clamping member 261 and the second clamping member 262 are symmetrically arranged.

[0029] Furthermore, it also includes a rigid brush 42 for cleaning and brushing the exposed portion of the cut and cleaned cable 5; the rigid brush 42 is detachably connected to the fixing frame 21, and the cleaning end of the rigid brush 42 is placed in the treatment area 22.

[0030] Furthermore, it also includes a control module, which is detachably connected to the device base 1, and is electrically connected to the fixing component 2, the cutting component 3 and the cleaning component 4 respectively.

[0031] In a specific embodiment, this embodiment provides an automated cable sheath processing device, which is particularly suitable for sheath stripping and insulation surface asphalt cleaning operations of 110kV and above large-diameter, high-hardness cables. The device mainly includes a device base 1, a fixing component 2, a cutting component 3, a cleaning component 4, and a control module. The control module is detachably connected to the device base 1 and electrically connected to each controlled component in the fixing component 2, the cutting component 3, and the cleaning component 4, respectively, for coordinating the automatic operation of each process.

[0032] Furthermore, the fixing component 2 is used to fix and limit the cable 5 to be processed, and to drive the cable 5 to complete axial movement and circumferential rotation during processing; such as Figure 2 As shown, the fixing component 2 includes a fixing frame 21, which is disposed opposite to the device base 1, and the two together enclose a processing area 22 for accommodating and processing the cable 5; To facilitate operation at any intermediate section of cable 5, a limiting rod 23 is hinged to one end of the fixing frame 21. A connecting block 24 is slidably provided on the end of the limiting rod 23 away from the fixing frame 21. The connecting block 24 can slide linearly relative to the limiting rod 23 to adjust the locking position, and can be detachably connected to the device base 1 by screws or quick buckles. When the connection between the connecting block 24 and the device base 1 is loosened, and the limiting rod 23 is flipped outward around its hinge point, a notch is formed at the original position of the limiting rod 23. At this time, the cable 5 can be directly put into the processing area 22 without having to be inserted from the end of the cable 5. After the cable 5 is inserted, the limiting rod 23 is restored and the connecting block 24 is locked to complete the radial limiting of the cable 5, so that the cable 5 is stably placed in the processing area 22.

[0033] To achieve precise feed drive for cable 5, a first moving module 25 is provided on the mounting bracket 21; such as Figure 2 As shown, the first moving module 25 includes a plurality of first axial clamping wheels 251 arranged at intervals along the axis of the processing area 22 and a plurality of second axial clamping wheels 252 corresponding to the number and position of the first axial clamping wheels 251. Among them, a number of first axial clamping wheels 251 are rotatably mounted on the fixed frame 21 through bearing seats, and a number of second axial clamping wheels 252 are correspondingly rotatably mounted on the device base 1. The first axial clamping wheels 251 and the second axial clamping wheels 252 are vertically opposite each other to form multiple pairs of clamping pairs. The first drive unit 254 is detachably mounted on the fixed frame 21. In this embodiment, the first drive unit 254 is a servo motor with a reducer. The output end of the first drive unit 254 is connected to a vertically arranged transmission rod 253. The upper end of the transmission rod 253 is circumferentially fixed to the transmission end of the first drive unit 254 and axially slidably engaged. The lower end of the transmission rod 253 has a thread on its outer surface and is threadedly connected to a nut block fixed on the device base 1. When the first drive member 254 rotates forward or reverse, it drives the transmission rod 253 to rotate within the nut block. Since the relative position of the transmission rod 253 and the fixed frame 21 in the axial direction remains unchanged, the entire fixed frame 21 will rise or fall relative to the device base 1, thereby adjusting the height of the processing area 22. This allows the first axial clamping wheels 251 and the second axial clamping wheels 252 to adapt to cables 5 of different diameters and apply appropriate clamping force to them. A second driving component (not shown in the attached figure) can also be detachably installed on the device base 1. The second driving component is also a servo motor. Its output end is connected to all the first axial clamping wheels 251 and all the second axial clamping wheels 252 through a gear set or synchronous belt pulley mechanism, so that when the cable 5 is clamped, all the clamping wheels can rotate synchronously in the same direction and drive the cable 5 to move smoothly along its axis by friction.

[0034] To achieve circumferential rotation drive of cable 5 to meet the requirements of annular cutting and circumferential cleaning, a second moving module 26 is also provided on the fixing frame 21; such as Figure 2 As shown, the second moving module 26 includes a first clamping member 261 and a second clamping member 262 with symmetrical structure and synchronized operation; the first clamping member 261 is mounted on the fixed frame 21, specifically including a first clamping wheel 2611 and a third driving member 2612 that drives the first clamping wheel 2611 to move up and down in the processing area 22 (from the perspective in the figure); the third driving member 2612 is a cylinder or an electric cylinder, the cylinder body of which is detachably connected to the fixed frame 21, and a bearing seat is fixed to the end of its piston rod, and the first clamping wheel 2611 is mounted on the bearing seat through a rotating shaft; Symmetrically, the second clamping member 262 is mounted on the device base 1, specifically including the second clamping wheel 2621 and the fourth driving member 2622 that drives the second clamping wheel 2621 to move horizontally forward and backward; the cylinder of the fourth driving member 2622 is detachably connected to the device base 1, and a bearing seat is fixed at the end of its piston rod, on which the second clamping wheel 2621 is mounted via a rotating shaft; The surfaces of the first clamping wheel 2611 and the second clamping wheel 2621 are both made of arc-shaped or high-friction material adapted to the surface of the cable 5, and the axes of both are parallel to the axis of the cable 5. A fifth driving component (not shown in the attached figure) can also be detachably installed on the fixing frame 21. The fifth driving component is a speed-regulating motor, and its output end is connected to the rotating shaft of the first clamping wheel 2611 and the second clamping wheel 2621 through a universal coupling or a flexible transmission shaft, thereby causing the cable 5 to rotate. In actual operation, the third drive member 2612 and the fourth drive member 2622 extend synchronously, pushing the first clamping wheel 2611 and the second clamping wheel 2621 to press the surface of the cable 5 or the exposed part of the cable 5 (such as the metal sheath or insulation layer after the sheath has been stripped) from both sides. Then the fifth drive member is activated, driving the two clamping wheels to rotate synchronously, thereby driving the cable 5 to rotate stably around its own axis.

[0035] Furthermore, the cutting assembly 3 is used to heat and soften the outer sheath of the cable 5 and to precisely remove it; such as Figure 2As shown, the cutting assembly 3 includes a heating element (not shown in the figure) and an ultrasonic cutting blade 31; the heating element is detachably mounted on the fixing frame 21, with its heating end pointing towards the cable 5 in the processing area 22; in this embodiment, the heating element is an infrared radiation heater with precise temperature control, an air-source heated hot air source, or a hot air gun, which can perform non-contact uniform preheating of the cable 5 sheath, softening it, especially for high-hardness metal sheaths or modified polymer sheaths, reducing the load and tool wear of subsequent cutting; in this embodiment, it is preferably based on an air-source heated hot air source, with the gas source coming from a nitrogen cylinder, and the heat source adopts an electric heating compressed gas heater, which converts electrical energy into heat energy and directly transfers the heat to the compressed gas flowing out of the air compressor, thereby realizing the process of gas heating and pressurization, and then spraying the heated gas onto the surface of the cable 5 through a nozzle; The ultrasonic cutter 31 is also detachably mounted on the mounting bracket 21 and located on the side of the heating element along the axial feed direction of the cable 5. The cutting end of the ultrasonic cutter 31 extends into the processing area 22. It consists of an ultrasonic generator, a transducer, and a titanium alloy cutter head. It achieves precise cutting with low pressure through high-frequency vibration. The cutting depth and vibration power of the ultrasonic cutter 31 can be set through the control module to ensure that only the designated sheath is cut through without damaging the internal insulation layer.

[0036] Furthermore, the cleaning component 4 is used to clean the exposed insulation surface of the cable 5 after the sheath has been cut and removed, removing adhering contaminants such as asphalt; for example... Figure 2 As shown, the cleaning assembly 4 includes a dry ice cleaning component 41 and a rigid brush 42; the dry ice cleaning component 41 is detachably connected to the device base 1, and its cleaning end, i.e. the nozzle, is placed in the treatment area 22 and points towards the insulation surface of the cable 5. The dry ice cleaning component 41 uses an external dry ice tank or other dry ice storage container to spray dry ice particles at high speed. By utilizing the kinetic energy transfer, low-temperature embrittlement and micro-explosion effect of the particles during impact, it can quickly peel off asphalt, oil and other substances attached to the insulation surface. Moreover, the dry ice particles sublimate directly without generating secondary pollution. The rigid brush 42 is detachably mounted on the mounting bracket 21, located downstream of the dry ice cleaning unit 41 in the axial movement direction of the cable 5. Its cleaning end is composed of dense metal bristles that are in close contact with the surface of the cable 5. After dry ice cleaning, as the cable 5 moves, the rigid brush 42 performs a rotating or linear mechanical brushing motion on the insulation surface, which can thoroughly remove stubborn residues that have been loosened by the impact of dry ice but have not completely fallen off, further improving the cleaning cleanliness.

[0037] Furthermore, the control module (not shown in the attached diagram) includes an operation panel, a PLC controller, and related drive circuits, which are detachably connected to the device base 1. The control module is electrically connected to the first drive component 254, the second drive component, the third drive component 2612, the fourth drive component 2622, the fifth drive component, the heating component, the ultrasonic cutting blade 31, the dry ice cleaning component 41, and related sensors (such as temperature sensors, limit switches, etc.). Through preset programs or manual commands, it coordinates the action sequence, speed, temperature, feed rate, and other parameters of each module to achieve one-click or segmented automated processing.

[0038] In the specific implementation process, firstly, according to the diameter of the cable 5 to be processed, the operation control module causes the first drive component 254 to move, and the height of the fixed frame 21 is adjusted by the transmission rod 253 so that the distance between the first axial clamping wheel 251 and the second axial clamping wheel 252 is slightly larger than the outer diameter of the cable 5. Then loosen the connecting block 24, flip open the limiting rod 23, and put the cable 5 radially into the processing area 22 so that the cable 5 falls on the second axial clamping wheel 252; close the limiting rod 23 and lock the connecting block 24 to complete the radial limiting of the cable 5; then, the first driving member 254 is finely adjusted again so that the upper and lower clamping wheels clamp the cable 5 with a preset pressure. After the automatic program is started, the heating element begins to heat the outer sheath of the starting section of the cable 5 to the preset softening temperature; after the temperature is reached, the second driving element is started, driving all the first axial clamping wheels 251 and the second axial clamping wheels 252 to rotate synchronously, and relying on friction to push the cable 5 to move axially towards the cutting station. When the end of cable 5 or the designated starting position reaches below the ultrasonic cutting blade 31, the ultrasonic cutting blade 31 cuts to the set depth. As the cable 5 moves axially, the axial cutting and grooving of the sheath is completed. For cases where circumferential cutting is required to peel off the sheath in sections, when the axial groove reaches the predetermined length, the second drive unit stops, and the first and second axial clamping wheels remain clamped to achieve axial positioning. At this time, the third drive unit 2612 and the fourth drive unit 2622 act synchronously, pushing the first clamping wheel 2611 and the second clamping wheel 2621 to clamp the exposed metal layer of the cable 5 sheath in the area that has been cut through. Then, the fifth drive unit drives the clamping wheel to rotate, causing the cable 5 to rotate circumferentially. During the rotation of cable 5, the ultrasonic cutting blade 31, which has been cut into place, completes the circumferential cut, completely breaking off the sheath of that section; after cutting, the clamping parts retract, and the sheath of that section can be easily removed by the operator manually or by an additional mechanism. The exposed insulation layer of cable 5 continues to move axially with cable 5, entering the cleaning station; the dry ice cleaning unit 41 is activated, spraying dry ice particles onto the insulation surface to remove adhering substances such as asphalt; at the same time, cable 5 can continue to move axially or rotate via the second moving module 26 to ensure that it is cleaned circumferentially. The area cleaned by dry ice is then brushed by rigid brush 42, whose bristles powerfully brush the insulation surface to thoroughly remove all residual dirt; After processing one section, the clamping of the first moving module 25 is released, and the cable 5 is clamped by the second moving module 26 and sent forward a distance to the second preset processing section. Then the clamping is switched to the first moving module 25. This cycle is repeated to continuously complete the sheath stripping and insulation cleaning of the entire cable 5 to be processed section. Throughout the entire operation, the coordination of all actions, the maintenance of heating temperature, and the adjustment of cutting and cleaning parameters are all automatically completed by the control module, which improves the efficiency of the operation, ensures consistent processing quality, and effectively avoids the risk of damage and labor intensity caused by manual operation.

[0039] This invention discloses an automated cable sheath processing device. This device integrates multiple processes, including cable 5 fixing, axial and circumferential driving, heating and softening, ultrasonic cutting, dry ice cleaning, and auxiliary brushing, into one unit. A control module enables coordinated linkage and automated control of each process, changing the inefficient traditional manual layer-by-layer stripping and cleaning method, and further improving work efficiency. Through the first and second moving modules 26 in the fixing component 2, the axial feed and circumferential rotation of the cable 5 can be precisely controlled. Combined with a precisely controlled ultrasonic cutting blade 31, constant force and constant depth sheath cutting can be achieved, effectively avoiding damage. The ultrasonic cutting method not only removes damage to the cable insulation layer but also ensures a smooth and flat stripping interface, thereby improving the quality of accessory manufacturing and long-term operational reliability. The non-contact ultrasonic cutting method also enhances operational safety. The overall device has a compact structure and reasonable layout. Through the innovative structure of the fixed frame 21 and the device base 1 hinged with the limiting rod 23, the cable 5 can be quickly and conveniently loaded into the processing area 22 without having to slip it on from the end of the cable 5. This is especially suitable for processing the middle section of long-distance cables 5. The modular design of the device makes it relatively small in size, which is convenient for transportation and deployment in narrow spaces such as cable trenches and tunnels, and is less restricted by the site environment.
