Description

Technical Field

[0001] This invention relates to the field of cable auxiliary tools, and more specifically to a high-voltage cable reactive force cone electric taper. Background Technology

[0002] With the acceleration of global urbanization and the continuous growth of electricity demand, cross-linked polyethylene (XLPE) high-voltage cables have become core equipment for urban power grid transmission and distribution due to their advantages such as excellent heat resistance, good insulation performance, and flexible laying. The manufacturing quality of intermediate joints directly determines the stability of power grid operation. According to industry statistics, more than 60% of cable line faults are caused by defects in intermediate joints. The main insulation reaction force cone, as a key component for joint insulation transition, is the core link in joint manufacturing by optimizing the cone surface geometry to disperse the electric field and avoid charge accumulation and breakdown. Moreover, with 10kV-35kV distribution network cables becoming mainstream, the industry's requirements for their manufacturing precision, efficiency, and application scenarios have increased significantly.

[0003] While the manufacturing of reaction cones has evolved from manual cutting and sandpaper polishing to automated equipment, existing technologies still have significant shortcomings. The cutting system disclosed in patent CN111531393A, although improving cutting quality, is a large piece of equipment only suitable for situations where cables are not installed. It requires a fixed working space, is not portable, and is difficult to adapt to complex on-site construction scenarios. The cutting system disclosed in patent CN118693714A can operate in the state of cable crimping, but relies on manual power, making it impossible to achieve uniform cutting speed and control the quality of the cone surface. Furthermore, traditional sleeve-type cone cutters are only compatible with a single cable specification, and in scenarios where cold-shrink intermediate joints are converted to wrap-around joints or where cable crimping is not broken, the core structure limits their use. Radial cutting is also constrained by space, making operation inconvenient and dangerous. These technologies cannot meet the high-precision, multi-scenario, and automated reaction cone manufacturing needs of power grid operation and maintenance. Therefore, the development of a high-precision electric cone cutter compatible with crimping states and multiple specifications has become an urgent industry need. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a high-voltage cable reactive force cone electric taper to solve the technical problems of the prior art being incompatible with multiple specifications of cables, unable to adapt to crimping operations, and having unstable quality of manual operation.

[0005] To solve the above problems, the technical solution of the present invention is as follows: a high-voltage cable reactive force cone electric taper includes a base, a power supply on the base, a frame on one side of the power supply, a clamping system for clamping the cable symmetrically arranged on both sides of the frame, a cutting system for cutting the cable arranged inside the frame, and a power system for providing power to the cutting system. It also includes a control box for controlling the clamping system, the cutting system, and the power system.

[0006] Furthermore, the power system includes a motor mounted on the frame, the output shaft of the motor passing through the frame and connected to a first gear via a belt, the first gear meshing with a second gear, the second gear being connected to the cutting system, and the second gear having an axially through structure for a cable to pass through.

[0007] Furthermore, the cutting system includes an electric slip ring connected to the second gear and a cutting device connected to the electric slip ring. The cutting device includes a cutting box connected to the electric slip ring, and a corresponding tool mechanism and positioning mechanism are provided inside the cutting box. Open slots for inserting cables are provided on the corresponding side walls of the cutting box.

[0008] Furthermore, the slip ring includes a rotor connected to the second gear, and a plurality of concave annular grooves are provided on the side wall of the rotor. It also includes an electric brush fixed to the frame and inserted into the electric brush, the electric brush including a U-shaped claw and a copper sheet connected to the claw.

[0009] Furthermore, the rotor and the second gear are separate structures. The rotor includes a rotor separation part and a rotor fixing part fixedly connected to the cutting box. The second gear includes a gear separation part fixedly connected to the rotor separation part and a gear fixing part fixedly connected to the rotor fixing part. A positioning pin is provided inside the cutting box to lock the electric slip ring to the cutting box by cooperating with the rotor separation part.

[0010] Furthermore, the tool mechanism includes a tool disposed inside the cutting box, a first stepper motor connected to the tool on the outside of the cutting box, and a first guide shaft connected to the tool passing through the cutting box.

[0011] Furthermore, the positioning mechanism includes upper and lower rollers arranged correspondingly inside the cutting box, the rollers being rotatably mounted on the positioning frame, a second stepper motor connected to the positioning frame on the outside of the cutting box, and a second guide shaft passing through the cutting box and connected to the positioning frame.

[0012] Furthermore, the first stepper motor and the second stepper motor are electrically connected to the conductive loop.

[0013] Furthermore, the clamping system includes a clamping motor located on one side of the frame. The output shaft of the clamping motor is connected to a coupling and a bidirectional clamping screw. A guide rail is provided on one side of the frame, and two sliders are slidably connected to the guide rail. Clamping jaws are provided on the sliders, and the bidirectional screw passes through the two clamping jaws.

[0014] Furthermore, it also includes a reset system, which includes a photoelectric switch located on one side of the first gear and fixed to the frame, and a magnet located on the first gear.

[0015] Compared with the prior art, the present invention has the following advantages: through the integrated design of the base, frame, clamping system, cutting system, power system and control box, the automated, high-precision and multi-scenario adaptability of cable reaction force cone manufacturing is realized, which significantly improves construction efficiency and joint quality.

[0016] The electric slip ring and the second gear adopt a split structure. With the open through groove on the side wall of the cutting box, the cable can be directly inserted into the device from the opening without cutting the crimped three-phase cable. This is perfect for special scenarios such as converting cold shrink intermediate joints into wrapping intermediate joints and emergency repairs after cable crimping. It solves the industry problems of traditional sleeve-type tapers being unable to fit and limited radial manual cutting space.

[0017] The device is controlled by a control box to manage the coordinated operation of the clamping system, cutting system, and power system. From cable clamping and tool feeding to rotary machining and automatic reset, the entire process is electric, requiring no manual power application. Only one operator is needed to complete the entire operation process. Compared with manual cutting, sanding, or semi-manual equipment, it significantly reduces manpower input and significantly improves the overall operation efficiency of reactive cone production.

[0018] The cutting system's tool mechanism and positioning mechanism are driven by the first and second stepper motors, respectively, and are uniformly controlled by a control box. With the precise guidance of the first guide shaft, the tool feed rate and the positioning roller fit can be digitally and precisely adjusted. The power system drives the cutting system to rotate at a uniform speed through belt and gear meshing, avoiding the problem of uneven speed in manual cutting. This ensures that the geometry of the reaction force cone surface approximates the theoretical complex logarithmic curve, resulting in a more uniform electric field distribution and effectively reducing the risk of insulation interface breakdown.

[0021] The electric high-voltage cable reaction cone cutter of the present invention is primarily applicable to 10kV-35kV cross-linked polyethylene high-voltage cables. It is especially suitable for reaction cone manufacturing scenarios where three-phase cables are in a crimped state, cold-shrink intermediate joints are converted to wrapped intermediate joints, and the cables do not need to be broken. It can realize automated and high-precision cutting of cables, and the entire process can be completed by a single person. It is effectively suitable for narrow construction spaces such as cable trenches and tunnels.

[0022] like Figure 1-6 As shown, the electric taper includes a base 1, a power supply 2, a frame 3, a clamping system 4, a cutting system 5, a power system 6, a control box 7, and a reset system. The frame 3 can be a structure with two vertical plates connected at the front end by a fixed plate. The power supply 2 is fixedly installed on the upper surface of the base 1, providing power support for all electric components of the entire device. The frame 3 is fixed on the upper surface of the base 1 and located on one side of the power supply 2. The clamping system 4 is symmetrically arranged on the left and right sides of the frame 3 for bidirectional clamping and positioning of the cable to be processed. The power system 6 is installed on the frame 3, providing power for the rotary cutting of the cutting system 5. The cutting system 5 is located inside the frame 3 and is connected to the power system 6 to complete the cutting operation of the cable reaction cone. The control box 7 is connected to the base 1 and electrically connected to the power supply 2, clamping system 4, cutting system 5, power system 6, and reset system, realizing centralized control and parameter adjustment of each system. The reset system works with each system to complete the automatic reset after cutting, ensuring the accuracy of the equipment in the next operation. The specific structure is as follows: like Figure 1 , 2As shown in Figure 4, the clamping system 4 is symmetrically arranged on both sides of the frame 3. The two structures are identical, including a clamping motor 401, a coupling 402, a bidirectional clamping screw 403, a guide rail 404, a slider 405, and a gripper 406. The guide rail 404 is horizontally fixed on the outer side walls of both sides of the frame 3. Two symmetrically arranged sliders 405 are slidably connected to each guide rail 404. The sliders 405 are detachably connected to the arc-shaped gripper 406, which facilitates the replacement of the gripper 406. The arc-shaped inner surface of the gripper 406 fits against the outer wall of the cable to improve clamping stability. The clamping motor 401 is fixed on the outer side wall (i.e., the fixing plate) of the frame 3. The output shaft of the clamping motor 401 passes through the side wall of the frame 3 and is coaxially fixed to the bidirectional clamping screw 403 through the coupling 402. The bidirectional clamping screw 403 is horizontally arranged and passes through the two grippers 406 on the same side, and is threadedly engaged with the grippers 406.

[0023] After the cable to be processed is initially placed in the device, the clamping motor 401 is started through the control box 7. The output shaft of the clamping motor 401 drives the bidirectional clamping screw 403 to rotate. Utilizing the transmission action of the bidirectional screw, the two sliders 405 are driven to slide along the guide rail 404 towards each other, thereby driving the two grippers 406 to retract synchronously towards the center until the arc-shaped inner surface of the grippers 406 is tightly attached to the outer wall of the cable, completing the bidirectional clamping and positioning of the cable. For high-voltage cables of different diameters, the rotation stroke of the clamping motor 401 can be adjusted through the control box 7 to achieve flexible adjustment of the clamping distance of the grippers 406, adapting to the clamping requirements of multiple cable specifications without the need to replace special clamping components, thus reducing operating costs.

[0024] like Figure 1 , 2 As shown in Figure 4, the power system 6 provides rotational power to the cutting system 5. Specifically, it includes a motor 601 fixedly mounted on the frame 3. The output shaft of the motor 601 passes through the side wall of the frame 3 and is connected to a first gear 603 via a belt 602. The first gear 603 meshes with a second gear 604. The second gear 604 is connected to the cutting system 5. The second gear 604 is designed as an axially through structure, that is, it has a through hole in the center for the cable to pass through. This design allows the cable to pass through the equipment, and the power transmission and cable positioning do not interfere with each other.

[0025] After the cable is clamped and positioned, the motor 601 is started through the control box 7. The output shaft of the motor 601 drives the first gear 603 to rotate, which in turn drives the second gear 604 to rotate. The second gear 604 rotates at a constant speed around the cable axis. The second gear 604 is connected to the cutting system 5, providing continuous and stable power for the rotary cutting of the cutting system 5. The combined transmission structure of the belt 602 and the gear has both transmission smoothness and power transmission efficiency, and the structure is compact, effectively reducing the overall size of the equipment and adapting to narrow construction scenarios.

[0026] like Figure 2 , 3 As shown in Figure 4, the cutting system 5 uses the electric slip ring 501 as the core power supply and transmission connector, and together with the cutting box 502, tool mechanism, positioning mechanism, and positioning pin 518, forms an integrated rotary cutting structure. It works in conjunction with the power system 6 to achieve precise and uniform rotary cutting of the high-voltage cable. Simultaneously, relying on its separable structural design, it adapts to the insertion processing requirements under cable crimping conditions. The cutting box 502 is a square structure with an open top and the rest being structural plates. The electric slip ring 501 includes a rotor 511 and a brush 513, as shown... Figure 5 , 6 As shown, the rotor 511 is fixedly connected to the second gear 604 and rotates synchronously with the second gear 604 driven by the power system 6. The side wall of the rotor 511 is provided with several concave annular groove conductive channels 512, which provide independent power supply channels for the first stepper motor 504 and the second stepper motor 508. The matching brush 513 is inserted into the conductive channel 512 by U-shaped claws 514. The copper sheet 515 of the brush 513 is tightly attached to the conductive channel 512, so as to realize the continuous movement from the stationary end to the rotating end during the rotation of the electric slip ring 501. The disconnected, contactless power transmission continuously supplies power to the first stepper motor 504 and the second stepper motor 508 inside the cutting box 502, ensuring the stability of the power of the tool mechanism and the positioning mechanism during the rotary cutting process. At the same time, the rotor 511 of the electric slip ring 501 is fixedly connected to the cutting box 502, synchronously transmitting the rotational power of the second gear 604 to the cutting box 502, so that the cutting box 502, the tool mechanism, and the positioning mechanism form a coaxial rotating whole with the electric slip ring 501 and the second gear 604, providing a power basis for the circumferential cutting of the cable.

[0027] like Figure 5As shown, the electric slip ring 501, rotor 511, and second gear 604 are both designed as separate units with internal penetration. The rotor 511 is divided into a rotor separation part 516 and a rotor fixing part 517, and the second gear 604 is divided into a gear separation part 605 and a gear fixing part 606. The rotor separation part 516 and the gear separation part 605 are fixedly connected, and the rotor fixing part 517 and the gear fixing part 606 are fixedly connected. The cutting box 502 and the rotor fixing part 517 are integrated structures. The positioning pin 518 through the side wall of the cutting box 502 cooperates with the rotor separation part 516 to lock and unlock the separate structure of the electric slip ring 501 and the second gear 604. Before operation, pull out the positioning pin 518 to release the lock on the rotor separation part 516. The rotor separation part 516 and gear separation part 605, and the rotor fixing part 517 and gear fixing part 606 can be manually pried open, so that the electric slip ring 501 and the second gear 604 form an open opening. This, together with the open through slots 510 on both sides of the cutting box 502, allows the cable to be inserted into the crimped state without breaking. After the cable is placed in place, close the split rotor 511 and the second gear 604, insert the positioning pin 518 into the cutting box 502 and engage it with the rotor separation part 516, thus completing the overall locking of the electric slip ring 501, the second gear 604 and the cutting box 502. This ensures the coaxiality and stability of the structure during the rotary cutting process and avoids radial swaying and displacement.

[0028] Furthermore, an inner liner 10 with an upper opening is provided on the inner wall of the rotor 511. The inner liner 10 is adapted to the inner diameter of the rotor 511. A shock-absorbing copper sleeve 11 is provided between the inner liner 10 and the vertical plate. The use of the inner liner 10 can reduce the friction of the rotor 511 and improve its service life.

[0029] like Figure 3 As shown, the cutting box 502 is equipped with a corresponding tool mechanism and a positioning mechanism. The tool mechanism includes a tool 503, a first stepper motor 504, and a first guide shaft 505. The first stepper motor 504 is fixed to the outer wall of the cutting box 502, and its output shaft passes through the side wall of the cutting box 502 and is fixedly connected to the tool 503. The first guide shaft 505 passes horizontally through the side wall of the cutting box 502 and is fixedly connected to the tool 503, providing guidance for the feed movement of the tool 503. The positioning mechanism includes a roller 50... 6. Positioning frame 507, second stepper motor 508 and first guide shaft 505, two rollers 506 are symmetrically arranged on the positioning frame 507, and the rollers 506 are rotatably connected to the positioning frame 507. The second stepper motor 508 is fixed to the outer wall of the cutting box 502, and its output shaft passes through the side wall of the cutting box 502 and is fixedly connected to the positioning frame 507. The second guide shaft 509 passes horizontally through the side wall of the cutting box 502 and is fixedly connected to the positioning frame 507, providing guidance for the movement of the positioning frame 507.

[0030] like Figure 3As shown, the first stepper motor 504 and the second stepper motor 508 can be through-type lead screw stepper motors, electrically connected to the brush 513. The brush 513 is a fixed component at the stationary end of the device, fixed to the non-rotating area of ​​the frame 3, such as the inner wall of the frame 3. It is engaged in the concave annular groove conductive ring 512 of the rotor 511 of the slip ring 501 by a U-shaped claw 514, forming a sliding contact with the rotor 511. The cutting box 502, the slip ring 501 rotor 511, and the second gear 604 are a fixed rotating whole, rotating around the cable driven by the power system 6. The brush 513 always remains stationary, and has a rotary-stationary engagement relationship with the cutting box 502 and the slip ring 501 rotor 511. Therefore, the two will not rotate synchronously. From the installation structure, the problem of wire entanglement caused by the brush 513 rotating with the cutting box 502 is eliminated. The power supply 2, control box 7 and stationary brush 513 are connected to the device. 3. The connection is made by wires. These wires are fixed and do not rotate, so there is no possibility of entanglement. The copper sheet 515 of the brush 513 is tightly attached to the concave annular groove conductive ring 512 on the side wall of the rotor 511 of the slip ring 501. When the rotor 511 rotates with the cutting box 502, the copper sheet 515 and the conductive ring 512 maintain a gapless sliding contact. The forward power supply path is: current through power supply 2 - control box 7 - copper sheet 515 - conductive ring 512 - stepper motor. The reverse return path is: stepper motor - another conductive ring 512 - copper sheet 515 of another set of brushes 513 - control box 7 - power supply 2, forming a complete current loop. The conductive ring 512 is directly rigidly connected to the first stepper motor 504 and the second stepper motor 508 on the cutting box 502, with no exposed wires. The conductive ring 512 directly transmits the received power to the two stepper motors to power the feed action of the tool mechanism and the positioning mechanism.

[0031] like Figure 2 As shown, after the cable is clamped and the device is closed, the second stepper motor 508 drives the positioning frame 507 to move along the first guide shaft 505 towards the cable until the outer walls of the upper and lower rollers 506 are tightly attached to the outer wall of the cable, completing the pre-cutting positioning of the cable and preventing axial or radial displacement of the cable during the rotational cutting process; at the same time, the first stepper motor 504 drives the tool 503 to move along the first guide shaft 505 towards the cable until the cutting end of the tool 503 contacts the surface of the cable to be cut. According to the manufacturing requirements of the reactive cone, the number of rotation steps of the first stepper motor 504 is adjusted through the control box 7 to precisely control the depth of cut of the tool 503 and realize the digital adjustment of the cutting depth.

[0032] like Figure 2 , 4As shown, after the cutter 503 and the positioning roller 506 are both adjusted to the preset position, the power system 6 drives the second gear 604, the electric slip ring 501 and the cutting box 502 to rotate at a constant speed around the cable axis. At this time, the cutter 503 moves in a circular motion with the cutting box 502 to rotate and cut the surface of the cable to be cut. The positioning roller 506 rotates synchronously with the cutting box 502 and always fits against the outer wall of the cable, playing an auxiliary positioning and guiding role. During the cutting process, the feed amount of the first stepper motor 504 can be adjusted in real time through the control box 7 to gradually adjust the cutting depth, so that the geometric shape of the reaction force cone is close to the theoretical complex logarithmic curve, ensuring uniform electric field distribution and effectively reducing the risk of breakdown at the insulation interface.

[0033] like Figure 4 As shown, the reset system includes a photoelectric switch 8 and a magnet 9. The photoelectric switch 8 is fixedly installed on the inner wall of the frame 3 and located on one side of the first gear 603. The magnet 9 is embedded on the end face of the first gear 603 and corresponds to the detection end of the photoelectric switch 8. The photoelectric switch 8 is electrically connected to the control box 7 and can transmit the detection signal to the control box 7.

[0034] like Figure 2 , 4 As shown, after the reactive cone cutting operation is completed, the control box 7 controls the first stepper motor 504 and the second stepper motor 508 to rotate in opposite directions, driving the tool 503 and the positioning roller 506 to move away from the cable and return to the initial position. At the same time, the power system 6 continues to drive the first gear 603 to rotate. When the photoelectric switch 8 detects the position of the magnet 9, it transmits the detection signal to the control box 7. The control box 7 automatically controls the motor 601 of the power system 6 to stop running. At this time, the first gear 603, the second gear 604 and the cutting system 5 all stop rotating and return to the initial position before the operation, completing the automatic reset of the entire device. No manual calibration is required, improving the convenience of operation and ensuring the accuracy of the next operation.

[0035] The electric taper for high-voltage cable reactive force cones of this invention achieves centralized and digital control throughout the entire process via control box 7. The overall operation flow is as follows: device opening and closing - cable placement and locking - clamping system 4 clamps the cable bidirectionally - positioning mechanism positions the cable closely - tool mechanism precisely feeds to the preset depth - power system 6 drives cutting system 5 to rotate at a uniform speed for cutting - after cutting, tool 503 and positioning mechanism retract - reset system achieves automatic reset - clamping system 4 releases the cable - device opening and closing removes the processed cable. The entire operation process requires no manual power application; only one operator needs to adjust various parameters and issue operation commands through control box 7, greatly improving work efficiency. At the same time, all systems work together to achieve precise control at every step, from cable clamping and positioning to cutting and reset, ensuring the manufacturing quality of the reactive force cone.

[0036] The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
