Description

Technical Field

[0001] This invention relates to the field of power cable construction and maintenance, and in particular to a multifunctional processing device suitable for cables. Background Technology

[0002] Distribution cables, with their advantages of stable transmission, reliable power supply, and compact footprint, are widely used in the power transmission links of urban power distribution networks, industrial power supply, and building power distribution systems. However, before fabricating distribution cable terminals and intermediate joints, the outer sheath, steel armor layer, inner sheath, copper shielding layer of each phase conductor, semi-conductive layer, and main insulation layer must be sequentially cut, stripped, and chamfered. This pretreatment process directly determines the joint insulation performance, electric field uniformity, and long-term operational reliability. Due to limitations such as the dispersed nature of traditional tools, reliance on experience for manual operation, and insufficient structural adaptability, the cable layer stripping process is prone to problems such as uncontrolled cutting depth, uneven cuts, or internal structural damage. Furthermore, frequent tool switching between different processes and cumbersome workflows restrict further improvements in pretreatment accuracy, construction efficiency, and operational safety, thus driving the development of distribution cable processing technology.

[0003] Current power distribution cable processing mainly relies on single-function tools such as electrician's knives, utility knives, manual circumferential cutters, or simple cutting discs. While these tools can meet basic stripping needs, they also have many shortcomings. For example, the tools have fragmented functions, requiring frequent tool changes to complete steps such as outer sheath removal, steel armor grooving, inner sheath treatment, and multi-layer stripping of phase wires. This results in lengthy operation procedures and low overall efficiency. Furthermore, the cutting depth depends entirely on the operator's feel and experience, lacking precise feeding and positioning mechanisms. This makes it easy to overcut and damage the steel armor, main insulation, or even the conductor, or to undercut, leading to difficulties in stripping and leaving behind... Insulation hazards and operational risks: Manual cutting of rigid cables with large cross-sections or thick sheaths is laborious and results in poor cut smoothness, with limited versatility for different wire diameters and layer thicknesses; cutting blades used for steel armor cutting often lack reliable protection, and the blade switching lacks a stable locking mechanism, posing a safety risk of cutting operators; at the same time, traditional tools have not formed a modular integration and standardized operation mode, and the ring cutting and chamfering of phase wire copper shielding, semi-conductive, and main insulation need to be carried out step by step, making it difficult to ensure the consistency of processing quality and failing to meet the standardized, efficient, and safe on-site construction requirements for power distribution cable joints.

[0004] Therefore, it is necessary to improve the existing tools and processes for handling power distribution cables. This will not only solve the problems of easy damage to the internal structure of cables, low work efficiency, and poor safety caused by manual operation, but also achieve the integration of multi-process tools, precise and controllable cutting depth, and stable and reliable positioning and feeding. Furthermore, it will improve the compatibility of cables of different specifications and the consistency of pretreatment quality, simplify on-site operation procedures, reduce labor costs, and achieve a synergistic improvement in the efficiency, standardization, and safety of power distribution cable pretreatment operations while ensuring the construction quality of cable joints and the reliability of long-term operation.

[0027] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0028] This invention discloses a multifunctional cable processing device, comprising: a cutter assembly having a plurality of working cutters for cutting cables, wherein the plurality of working cutters can be controlled and selectively moved to a working position and operated; a positioning mechanism, wherein the plurality of working cutters are mounted on the positioning mechanism and driven by the positioning mechanism to move the working cutters to a set position on the cable; a fixing mechanism disposed on one side of the positioning mechanism for detachably fixing the cable; and a single-phase processing clamp 19 slidably disposed on the other side of the positioning mechanism for stripping and chamfering the cable. The fixing mechanism typically employs an adjustable clamp structure, made of high-strength material, with an anti-slip rubber pad added to the inner side of the clamp. Bolt-locking fixation allows for flexible adjustment based on cable diameter, enabling detachable cable fixation and effectively preventing cable slippage during processing. This ensures operational safety and avoids damage to the cable insulation. The tool assembly typically includes stripping, cutting, or trimming tools, all securely mounted on a tool holder. The tool holder can be directly connected to the sliding guide rail of the positioning mechanism. A solenoid reversing valve precisely controls the selection and switching of tools, ensuring only one tool moves to the working position at a time, avoiding interference. Alternatively, the positioning mechanism can employ a ball screw drive structure driven by a stepper motor, offering high transmission efficiency and precise positioning. This allows for accurate control of the tool feed and movement position, smoothly delivering the selected tool to the corresponding working position, adapting to diverse processing needs. The single-phase processing clamp 19 can adopt an openable structure with a built-in arc-shaped slot and positioning block. During operation, it tightly clamps the phase wire of the cable. The built-in small drive motor drives the stripping blade to rotate, quickly completing the stripping of the phase wire insulation layer. At the same time, the chamfering grinding head in the slot moves synchronously to chamfer the end of the phase wire, avoiding the sharp end from scratching the insulation layer. The various mechanisms work together tacitly, greatly improving the processing efficiency and quality, which will not be described in detail here.

[0029] In this embodiment, the fixing mechanism includes a circular washer 1, a circular turntable, and several cable fixing components 2. The circular turntable has an outer ring 3 and an inner ring 4. The circular washer 1 is fixedly connected to the inner ring 4, and the inner ring 4 is rotatably engaged with the outer ring 3. Several cable fixing components 2 are disposed on the circular washer 1 for detachable cable fixing. The circular turntable consists of an outer ring 3 and an inner ring 4, which are rotatably connected by a clearance fit. The outer ring 3 is usually fixedly installed on the bracket of the device, and the inner ring 4 can rotate flexibly relative to the outer ring 3 to facilitate adjustment of the cable handling angle. The circular washer 1 is made of insulating and wear-resistant material and is fixedly connected to the inner side of the inner ring 4 by countersunk bolts. The two are coaxially arranged to ensure a stable connection without affecting the rotation of the inner ring 4. Several cable fixing components 2 are evenly distributed on the circular ring. The inner circumference of washer 1 is arranged in a ring array to accommodate the fixing needs of cables of different specifications. The cable fixing component 2 adopts an adjustable tightening structure, including a tightening bolt and an arc-shaped top block. The inner side of the arc-shaped top block is attached with an anti-slip insulating pad. Tightening the tightening bolt can drive the arc-shaped top block to move, thereby clamping and loosening the cable and achieving a detachable fixing effect. During operation, the cable is passed through the ring washer 1, and the cable fixing components 2 are adjusted to clamp the cable. Rotating the inner ring 4 of the turntable can drive the cable to rotate synchronously. With the help of the positioning mechanism and the cutter assembly, the cable is processed at different angles while avoiding cable slippage and ensuring processing accuracy. The ring washer 1 is inserted into the cable to be processed. By tightening the three cable fixing components 2 in sequence, the rubber pads 7 at the top of the cable are evenly clamped on the outer surface of the cable from three directions, and the device is firmly fixed. After fixing, the outer ring 3 of the turntable can rotate smoothly relative to the cable through the ball bearings 6.

[0030] In this embodiment, the inner ring 4 of the turntable rotates with the outer ring 3 of the turntable via ball bearings 6. A plurality of cable fixing components 2 are evenly distributed around the circumference of the annular washer 1, and each cable fixing component 2 has a rubber pad 7 near the end of the cable. The inner ring 4 and the outer ring 3 of the turntable rotate with each other via ball bearings 6. An annular ball bearing groove is formed on the inner side of the outer ring 3, and the ball bearings 6 are embedded in the groove, allowing the inner ring 4 to rotate flexibly and smoothly relative to the outer ring 3, reducing friction and ensuring precise positioning, facilitating adjustment of the cable handling angle. A plurality of cable fixing components 2 are evenly distributed around the circumference of the annular washer 1 in a circular array, adaptable to cables of different specifications. The cable fixing component 2 can be an adjustable tightening structure or a knob bolt. In this embodiment, there are three cable fixing components 2, each with a rubber pad 7 near the end of the cable. The rubber pad 7 is made of flexible insulating material, which increases the friction with the cable, firmly clamping the cable to prevent slippage and avoiding damage to the cable insulation layer during clamping. Further details are omitted here.

[0031] In this embodiment, the positioning mechanism includes a telescopic rod 8, a first rotation limiting member 5, a first sliding member 9, and a baffle 17. The first end of the first rotation limiting member 5 is fixed to the outer ring 3 of the turntable, and the second end is installed on the telescopic rod 8. In use, the first rotation limiting member 5 can be controlled to rotate along a set angle, so that the telescopic rod 8 can be extended or retracted. The first sliding member 9 is slidably disposed on the telescopic rod 8 and can be locked. The baffle 17 is fixedly installed on the side of the first sliding member 9. The first rotation limiting member 5 can adopt a rotatable structure. Its first end is fixed to the outer ring 3 of the turntable by bolts and is firmly connected to the outer ring 3 of the turntable. The second end is detachably connected to the telescopic rod 8, which is convenient for later maintenance and replacement. In use, the first rotation limiting member 5 can be rotated along a set angle, usually 90°, by means of an external control button or manual adjustment, thereby driving the telescopic rod 8 to extend or retract. This allows the telescopic rod 8 to switch between an operating state perpendicular to the cable axis and a retracted state parallel to the cable axis. The rotation angle range is precise and controllable, avoiding excessive rotation that could damage the mechanism. The first sliding member 9 is slidably sleeved on the outside of the telescopic rod 8. Typically, a slide rail is provided on the telescopic rod 8, allowing the first sliding member 9 to slide on the slide rail. This is a conventional setup in existing technology and will not be elaborated further. The sliding is smooth and without jamming. A locking bolt is provided on the sliding member; after sliding to the target position, tightening the locking bolt secures it and prevents displacement during operation. The baffle 17 is made of rigid material and is welded to the side of the first sliding member 9, remaining perpendicular to the telescopic rod 8. Its function is to limit the tool assembly, ensuring that the tool assembly accurately stops when it moves to the set working position and corresponds with the cable on the fixing mechanism, ensuring processing accuracy. The overall mechanism, in conjunction with the fixing mechanism, achieves efficient and precise cable processing, which will not be elaborated further.

[0032] In this embodiment, the telescopic rod 8 is equipped with a scale and can be controlled to extend or retract. The baffle 17 is a frame-shaped baffle, and the bottom of the frame-shaped baffle is equipped with baffle ball bearings 18 for supporting the cable. The telescopic rod 8 is equipped with a scale that clearly marks the length, making it easy for operators to accurately control the extension or retraction amount. The telescopic rod 8 can be adjusted for extension and retraction via an external control component to adapt to the handling needs of different cable specifications. The first sliding member 9 is slidably sleeved on the telescopic rod 8 and locked and fixed by locking bolts to prevent displacement during operation. The baffle 17 is a frame structure, which is welded... Fixed to the side of the first sliding member 9, perpendicular to the telescopic rod 8; the bottom of the frame-shaped baffle is equipped with baffle ball bearings 18, which can roll flexibly, providing support for the cable and reducing friction during cable rotation or movement, thus preventing cable damage. Simultaneously, in conjunction with the scale and telescopic rod extension function, it further improves feed positioning accuracy. Pressing the small pressure plate on the first rotation limit member 5 unfolds the telescopic rod 8 from its retracted state (parallel to the cable) to its working state (perpendicular to the cable). Depending on the operational needs, pull the telescopic rod 8 to a suitable length and refer to the scale on it to determine the axial position. Slide the first sliding member 9 to the required radial position and tighten the locking screw. At this time, the baffle 17 and its baffle ball bearings 18 should fit against the cable surface, providing support; further details are omitted here.

[0033] In this embodiment, the tool assembly includes a disc damping shaft 11 and a screw 10. The shaft of the disc damping shaft 11 is mounted on a first sliding member 9 via the screw 10. A second rotation limiting member 12 and a third rotation limiting member 14 are provided on the disc of the disc damping shaft 11. A plurality of working tools are mounted on the disc via the second rotation limiting member 12 or the third rotation limiting member 14, and the plurality of working tools are selectively moved to the working position and work by rotating the disc damping shaft 11. The upper end of the shaft of the disc damping shaft 11 has a... A threaded hole is provided through which the screw 10 passes, securely mounting the disc damping shaft 11 to the first sliding member. The connection is tight and easy to disassemble, facilitating subsequent tool maintenance and replacement. A second rotation limiter 12 and a third rotation limiter 14 are fixedly provided on the disc of the disc damping shaft 11. The two are symmetrically distributed on the disc and are used to mount the working tools. Several working tools (such as peeling knives or cutting knives) are respectively fixed to the second rotation limiter 12 or the third rotation limiter 14 by bolts. The rotation limiter can restrict the shaking of the working tools and ensure working stability. In use, the operator can manually rotate the disc damping shaft 11. Utilizing its damping characteristics, the disc can rotate smoothly and be positioned at any angle. By rotating the disc, all the cutting tools can be rotated synchronously, thereby selecting one of the target cutting tools to move to the corresponding working position, aligning it with the cable on the fixed mechanism. In conjunction with the feeding action of the positioning mechanism, the cable processing operation is completed. The overall structure is simple, and the switching is precise and efficient. Of course, a cutting tool is installed in each of the four orthogonal directions of the disc damping shaft 11 through a rotation limiter, which will not be described in detail here.

[0034] In this embodiment, the screw 10 passes through the top surface of the first sliding member 9 and extends outward to form an extension. The extension is provided with a first screw knob 1001 for adjusting the feed depth of the working tool. The upper end of the disc damping shaft 11 has a threaded hole for threaded connection with the screw 10, thus securely mounting it to the first sliding member 9. The second rotation limiter 12 and the third rotation limiter 14 on the disc fix the working tool. Rotating the disc damping shaft 11 allows for selective switching of the tool to the working position. Rotating the first screw knob 1001 drives the screw 10 to move up and down, thereby moving the disc damping shaft. The rotating shaft 11 and the cutting tool rise and fall synchronously, precisely adjusting the tool feed depth, making operation convenient and positioning accurate. Alternatively, a screw handle can be installed on the extension, equipped with a first screw knob 1001. Rotating the first screw knob 1001 allows for precise control of the cutting depth of the blade, such as a feed of 1.5mm per revolution, and includes a 360° scale indicator. The screw 10 and the first screw knob 1001 should work in conjunction with the baffle 17 to ensure that the cable is stably clamped between the working tool and the baffle ball 18 during cutting, preventing the working tool from deviating. Further details are omitted here.

[0035] In this embodiment, the plurality of working tools include at least a first working tool 13 and a second working tool 16. The first working tool 13 is a bearing-type cutter for circumferential or longitudinal cutting of cable outer sheaths, and the second working tool 16 is a cutting disc driven by a drive motor 15. The first rotation limiter 5 and the third rotation limiter 14 are 90° self-locking hinges, and the second rotation limiter 12 is a 180° self-locking hinge. The first working tool 13 is a bearing-type cutter specifically designed for circumferential or longitudinal cutting of cable outer sheaths, providing smooth operation and minimizing damage to the inner layer of the cable. The second working tool 16 is a cutting disc powered by a drive motor 15, offering high cutting efficiency, adaptability to cables of different thicknesses, and is equipped with a protective cover. The limiters have different specifications; the first rotation limiter 5 and the third rotation limiter 14 are both 90° self-locking hinges, enabling rotation within a 90° range and self-locking to ensure the stability of the mechanism. The second rotation limiter 12 is a 180° self-locking hinge. Larger size, adaptable to different installation needs. The first working tool 13 and the second working tool 16 are respectively installed on the corresponding limiting parts. The screw 10 passes through the first sliding part 9 and extends to form an extension with a first screw knob 1001. The rotating disc damping shaft 11 can select one tool to switch. Rotating the knob can adjust the feed depth. All components work together to achieve precise and efficient processing. It can also be equipped with a utility knife for cutting the inner sheath or a marker for marking the cutting position. The rotating disc damping shaft 11 can hold the first working tool... The second rotation limiter 12 of 13 is turned to 180° to unfold it. Hold the first screw knob 1001 and rotate the first screw knob 1001 to bring the first working tool 13 close to the cable. Rotate the first screw knob 1001 for fine adjustment and set the feed amount according to the thickness of the outer sheath. For example, the feed is 1.5mm per revolution. After the first working tool 13 cuts into the sheath, hold the first screw knob 1001 and rotate the outer ring 3 of the turntable to drive the entire tool to rotate around the cable once to complete the circumferential cutting. This will not be described in detail here.

[0036] In this embodiment, a second sliding member 27 and a connecting rod 28 are also included. The second sliding member 27 is slidably disposed on the telescopic rod 8 and can be locked. The single-phase processing fixture 19 is installed on the second sliding member 27 via the connecting rod 28. The single-phase processing fixture 19 is a disc structure with a central hole. The outer circle of the disc structure has second screw knobs 20 on the left and right sides, and the inner circle has a plurality of blade knobs 21 evenly distributed circumferentially. Each blade knob 21 controls the corresponding blade that is in transmission cooperation with the blade knob 21. The second sliding member 27 is located on the first sliding member 9 away from the fixing mechanism. On the side, the second sliding member 27 is slidably sleeved on the telescopic rod 8, and has the same structure as the first sliding member 9. Both adopt a clearance fit design and are equipped with locking bolts, which will not be described in detail here. The second sliding member 27 is located on the side of the first sliding member 9 away from the fixing mechanism. The two are spaced apart and do not interfere with each other. They correspond to the installation and positioning of the tool assembly and the single-phase processing fixture 19, respectively. The single-phase processing fixture 19 is fixedly installed on the second sliding member 27 through the connecting rod 28. The connecting rod 28 is made of rigid material, and its two ends are detachably connected to the second sliding member 27 and the single-phase processing fixture 19, respectively, for easy maintenance and replacement. The single-phase processing fixture 19 is a disc structure with a central hole for the phase wire of the cable to pass through. Second screw knobs 20 are located on the left and right sides of its outer circumference for adjusting the tightness of the fixture to secure the phase wire. Several blade knobs 21 are evenly distributed circumferentially along the inner circumference. Each blade knob 21 is driven by a corresponding blade. Rotating the blade knobs allows for precise adjustment of the blade extension and retraction, enabling phase wire stripping and chamfering. All components work together to adapt to different phase wire specifications, ensuring processing accuracy and efficiency. The single-phase processing fixture 19 is a disc with a diameter of 100mm and a central 45mm hole. The disc has two second screw knobs 20 located on the left and right sides and four blade knobs 21. Each blade knob 21 operates independently... The corresponding slider 22 is controlled by a control panel. Each slider 22 is equipped with a blade for processing different phase wire structures of the cable. After the inner sheath is removed, the three phase wires are exposed. At this time, the position of the second sliding member 27 installed on the telescopic rod 8 is adjusted so that the single-phase processing clamp 19 at the end of the connecting rod 28 is aligned with a certain phase cable to be processed, and the second sliding member 27 is locked. The central hole of the single-phase processing clamp 19 is inserted into the phase cable. The second screw knobs 20 on the left and right sides of the clamp are rotated so that the internal slider 22 clamps the cable. When cutting the copper shielding layer, the corresponding blade knob 21 is rotated so that the third blade 25 slightly cuts into the shielding layer. Then, the single-phase processing clamp 19 is rotated one full turn to circumferentially cut and remove the shielding layer. Similarly, the third blade 25 can be used to circumferentially cut and remove the semiconductive layer. When processing the main insulation layer, the corresponding blade knob 21 is rotated so that the extension length of the first blade 23 matches the thickness of the main insulation. The clamp is rotated and pushed towards the end of the cable to remove the main insulation of the predetermined length.Finally, use the corresponding chamfering blades (the second blade 24 is for main insulation chamfering, and the fourth blade 26 is for semi-conductive chamfering) to chamfer the cross-section of the insulation layer; after completing the treatment of one phase, release the clamp, move the second sliding member 27 to the position of the next phase cable, and repeat the above operation.

[0037] In this embodiment, the blades include a first blade 23, a second blade 24, a third blade 25, and a fourth blade 26. The first blade 23, the second blade 24, the third blade 25, and the fourth blade 26 have different structures to adapt to different processing requirements of the phase wires. The four blades are respectively driven and cooperate with the corresponding blade knob 21. Rotating the knob can independently adjust the extension and retraction of each blade. The first blade 23 is used for circumferential cutting of the main insulation layer, i.e., the main insulation layer circumferential cutting blade; the second blade 24 is used for chamfering the main insulation layer, i.e., the main insulation chamfering blade; the third blade 25 is used for circumferential cutting of the copper shielding layer or the semiconductive layer of the cable, i.e., the copper shielding layer or the semiconductive layer circumferential cutting blade; and the fourth blade 26 is used for chamfering the semiconductive layer, i.e., the semiconductive layer chamfering blade.
