Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically to a cable stripping device. Background Technology

[0002] As a key piece of equipment in the power system responsible for transmitting high-voltage electrical energy, power cables consist of a conductor and an insulation or armor layer tightly wrapped around it. Driven by the development needs of smart grid construction and the large-scale integration of new energy sources, power cables are widely used in overhead transmission lines, large industrial and mining enterprises, high-voltage switching stations, and distribution networks to ensure the continuous and stable distribution of electricity. Before installation or maintenance, one end of the cable is usually stripped, that is, the insulation or armor layer is removed from the conductor to facilitate subsequent wiring, terminal fabrication, or maintenance operations.

[0003] Currently, relevant technologies are available for cable stripping operations. For example, Chinese patent document CN118589358A discloses a cable stripping device, which includes a base with two sets of control handles symmetrically installed at the bottom. A first groove is provided at the top of the base, and a sliding shell is slidably connected within the first groove. The top of the sliding shell is arc-shaped and has a rotating groove. The device also includes a positioning and cutting mechanism, which includes a rotating ring rotatably connected within the rotating groove. A driven gear is fixedly installed on the outside of the rotating ring, and three sets of second grooves are evenly distributed along one side of the rotating ring. Through the cooperation of the moving mechanism, the positioning and cutting mechanism, and the driving mechanism, the device can quickly complete the positioning, fixing, and precise cutting and stripping operations of high-voltage cables with larger diameters, thereby improving the stripping efficiency in high-altitude operation scenarios to a certain extent.

[0004] However, the aforementioned device can only strip cables of specific specifications (i.e., specific cross-sectional diameters). In actual power systems, the selection of cable specifications is influenced by a variety of factors, including load current, transmission distance, short-circuit thermal stability, and mechanical strength, resulting in a diversity of cable thicknesses used in construction. Cables of different thicknesses also have significant differences in the thickness of their insulation or armor layers. If only a stripping structure with a single cutting depth is used, it will be difficult to meet the stripping requirements of cables of different specifications. This can easily lead to problems such as cutting too deep and damaging the wire core or cutting too shallow and failing to effectively strip the cable, thus affecting the quality and efficiency of construction. Summary of the Invention

[0005] The actual technical problem to be solved by this application is: how to adapt to cables of different specifications and achieve stripping treatment with adjustable cutting depth.

[0006] This invention provides the following technical solution: a cable stripping device, comprising a machine tool, a circumferential cutting system rotatably mounted above the machine tool for stripping the armor or insulation layer of the cable end, and a first drive mechanism for controlling the operation of the circumferential cutting system. The circumferential cutting system includes a wheel that can rotate under the drive of the first drive mechanism, an adjusting plate rotatably mounted on the side wall of the wheel, and a second drive mechanism mounted on the side wall of the wheel for controlling the adjustment angle of the adjusting plate. The adjusting plate has at least one inclined guide groove on its surface. The circumferential cutting system also includes a retractable cutting tool corresponding to the guide groove, which movably passes through the guide groove and slides radially along the wheel. By adjusting the rotation direction and revolution angle of the adjusting plate around the center, the radial feed depth of the retractable cutting tool is adjusted, and it rotates in conjunction with the wheel, so that the retractable cutting tool strips the armor or insulation layer of cables of different specifications in a progressively deeper circumferential cutting manner.

[0007] Furthermore, the end face of the wheel is provided with a first gear ring that meshes with the drive gear in the first drive mechanism, and a rotating ring that is rotatably connected to a support fixed on the top of the processing table.

[0008] Furthermore, the adjustment disc is provided with a ring rail that is movably fitted with the annular opening of the disc sidewall, and a second gear ring that meshes with the gear roller in the second drive mechanism, so as to receive torque input and rotate along the annular opening for adjustment.

[0009] Furthermore, the adjustment disc and the wheel are provided with a second through hole and a first through hole that are aligned and connected in the middle; the surface of the adjustment disc is provided with a guide groove that deviates from the radial direction and extends at an inclination, and the wheel is provided with a radial groove that corresponds to the guide groove; the retractable cutting tool moves through the guide groove and slides with the radial groove, and when the guide groove rotates around the center, it pulls the cutting tool to slide along the radial groove to adjust the inner diameter of the circle it encloses.

[0010] Furthermore, the retractable cutting tool includes a tool holder, which is composed of a movable pin that movably passes through the guide groove and a limiting block that is slidably sleeved in the radial groove. The side wall of the radial groove is provided with a through-hole for the movable pin to slide radially. It also includes a tool holder fixed to the end of the movable pin and a cutting blade installed on the periphery of the tool holder and facing the center.

[0011] Furthermore, the tool holder has a drive rack on both sides, an arc-shaped seat plate fixed to the side wall of the wheel disk, a reversing gear that meshes with the drive rack and a protective part that is connected to the reversing gear and moves along the track of the arc-shaped seat plate. The protective part moves radially with the retractable tool to achieve lubrication and protection of the cutting edge.

[0012] Furthermore, the protective part includes a driven rack that meshes with the reversing gear and can translate along the track. The driven rack is fixed with protective lubricants located on both sides of the cutter by a fork. When the retractable cutter moves radially toward the center, the protective lubricants move away from the center and rub against the blade to achieve self-lubrication. When the retractable cutter moves radially away from the center, the protective lubricants conform to the blade to the center to seal the blade.

[0013] Furthermore, the driving rack and the driven rack are staggered on different longitudinal planes to avoid motion interference; the reversing gear has axial depth to simultaneously mesh with the driving rack and the driven rack; the maximum length of the driven rack extending toward the cutter holder does not hinder its radial displacement toward the center; the fork is fixed to the side wall of the driven rack, its bottom end is forked and inclined toward the center, and is fixed with a protective lubricating element parallel to the cutter.

[0014] Furthermore, the cutter has a cross-sectional width that varies radially, and the protective lubrication component is provided with an oil reservoir and an oil outlet structure that is attached to the side wall of the cutter. When the cutter moves radially, the change in cross-sectional width squeezes out oil to achieve self-lubrication.

[0015] Furthermore, the device also includes a cutting depth determination system, which includes a power connector, a power terminal, a power module, and an alarm unit. The metal cutter forms a circuit switch, which closes the circuit and triggers an alarm when it touches the wire core.

[0016] The technical effects and advantages of this invention are as follows:

[0017] By adjusting the rotation direction and angle of the adjustment disc, the guide groove is driven to revolve around the center and change its contact position with the blade holder, thereby precisely adjusting the radial feed depth of the cutter. In conjunction with the integrated rotation of the wheel, multiple cutters perform stripping of the armor or insulation layers of cables of different specifications in a progressively deeper circumferential cutting manner. This effectively adapts to differences in cable thickness and layer thickness, avoiding problems such as cutting too deeply and damaging the wire core or cutting too shallowly and failing to strip the wire, significantly improving stripping quality and construction efficiency. At the same time, the reverse rotation allows the retractable cutter to automatically return to its initial position, facilitating quick reset for the next round of stripping tasks. The operation is convenient and meets diverse construction needs. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cable processing stripping device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, refer to Figures 1 to 8 As shown, the present invention provides a cable stripping device, including a machine tool, a circumferential cutting system rotatably disposed above the machine tool for stripping the armor layer or insulation layer of the cable end, and a first drive mechanism 3 for controlling the operation of the circumferential cutting system; the circumferential cutting system includes a wheel 4 rotatable under the drive of the first drive mechanism 3, an adjusting plate 5 rotatably disposed on the side wall of the wheel 4, and a second drive mechanism 6 installed on the side wall of the wheel 4 for controlling the adjustment plate 5 to adjust its rotation angle; the surface of the adjusting plate 5 is provided with at least one inclined guide groove 51. The circumferential cutting system also includes a retractable cutting tool corresponding to the guide groove 51. The retractable cutting tool moves through the guide groove 51 and slides radially along the wheel 4. By adjusting the rotation direction and revolution angle around the center of the adjustment disk 5, the radial feed depth of the retractable cutting tool can be precisely adjusted. It also rotates in conjunction with the wheel 4, so that the retractable cutting tool can peel off the armor layer or insulation layer of cables of different specifications in a progressively deeper circumferential cutting manner. This effectively adapts to the differences in cable thickness and layer thickness, and avoids the problem of cutting too deeply and damaging the wire core or cutting too shallowly and being unable to peel off the wire core.

[0036] The end face of the wheel 4 has a first gear ring 43 that meshes with the drive gear 31 in the first drive mechanism 3 to receive torque input; the end face of the wheel 4 is also provided with a rotating ring 44 that is rotatably connected to the support 2 fixed on the top of the processing table 1. The two can be engaged by a slotted rotation to ensure stable rotation without derailment; the first drive mechanism 3 includes a drive gear 31, a first motor 33 mounted on the top wall of the processing table 1, and a coupling 32 that fixes the drive gear 31 and the output shaft of the first motor 33; the output torque of the first motor 33 is transmitted to the first gear ring 43 via the drive gear 31 to drive the wheel 4 to rotate, so that the rotation direction and range of the wheel 4 are controllable;

[0037] The adjusting disc 5 has a ring rail 54 that is movably fitted into the annular opening of the side wall of the disc 4, and a second gear ring 53 that meshes with the toothed roller 61 in the second drive mechanism 6, for receiving torque input and rotating stably along the annular opening for adjustment; the second drive mechanism 6 includes a toothed roller 61, a mounting base 62 fixed on the side wall of the disc 4 and located around the second gear ring 53, a second motor 64 mounted on the other end of the mounting base 62, and a synchronous pulley group 63 that drives the toothed roller 61 and the second motor 64; the output torque of the second motor 64 is transmitted to the second gear ring 53 via the toothed roller 61 to drive the adjusting disc 5 to rotate, so that the rotation direction and range of the adjusting disc 5 are controllable; Note: the adjusting disc 5 can rotate within a certain range along the annular opening of the side wall of the disc 4 under the drive of the second drive mechanism 6 to adjust the retracting radius of the retracting cutter; at the same time, the second drive mechanism 6, the adjusting disc 5 and the retracting cutter rotate together with the disc 4, and the two cooperate to complete the control of the cable cutting depth;

[0038] The middle of the adjusting disk 5 and the wheel 4 is provided with a second wire passage hole 52 and a first wire passage hole 42 that are aligned and connected for the cable to pass through; the surface of the adjusting disk 5 is provided with a guide groove 51 that is offset from the radial direction and extends at an inclination, one end of which is close to the second wire passage hole 52 and the other end is adjacent to the second gear ring 53; a radial groove 41 corresponding to the guide groove 51 is provided along the radial direction of the wheel 4; the retractable cutting tool moves through the guide groove 51 and slides with the radial groove 41. When the guide groove 51 rotates around the center, it can pull the retractable cutting tool to slide along the radial groove 41 to adjust the inner circle diameter enclosed by the retractable cutting tool, i.e., the cutting depth.

[0039] The retractable cutting tool includes a tool holder 7, which is integrally formed by a movable pin 71 that movably passes through the guide groove 51 and a limiting block 72 that is slidably sleeved in the radial groove 41. The side wall of the radial groove 41 has an opening 411 for the movable pin 71 to slide radially. The retractable cutting tool also includes a tool holder 8 fixed to the end of the movable pin 71 and a cutting blade 9 installed on the periphery of the tool holder 8 and facing the center. The tool holder 8 preferably slides against the side wall of the adjusting plate 5. By adjusting the rotation direction and angle of the adjusting plate 5, the guide groove 51 is driven to revolve around the center and the contact position with the tool holder 7 is changed, thereby precisely adjusting the radial feed depth of the cutting blade 9. It also works in conjunction with the rotating wheel 4 to allow multiple cutting blades 9 to strip the armor layer or insulation layer of cables of different specifications in a progressively deeper circumferential cutting manner.

[0040] Example 2: In order to achieve automatic lubrication of the cutting edge and effective protection during the cutting process and when not in operation, thereby reducing mechanical wear and improving peeling effect, refer to... Figures 9 to 15 As shown, drive racks 10 are arranged opposite each other on both sides of the same tool holder 8. One end of the drive rack 10 is bent and fixed to the periphery of the tool holder 8, and the other end extends outward and is parallel to the central axis of the tool holder 8 and the adjusting plate 5. An arc-shaped seat plate 11 located around the second gear ring 53 is fixed on the side wall of the wheel 4. A reversing gear 12 is rotatably arranged on the side of the arc-shaped seat plate 11 close to the drive rack 10. A protective part is arranged in a direction perpendicular to the drive rack 10 and is connected to the reversing gear 12. The protective part can move axially along the track on the surface of the arc-shaped seat plate 11 under the rotation of the reversing gear 12. It realizes the lubrication and protection mechanism of the cutting edge in conjunction with the radial movement of the retractable cutting tool: when the retractable cutting tool moves radially towards the center, the protective part retracts and rubs against each other to lubricate the cutting edge; when the retractable cutting tool moves away from the center, the protective part resets and closes to protect the cutting edge.

[0041] The surface of the arc-shaped base plate 11 is provided with a track perpendicular to the moving direction of the retractable cutter. The protective part includes a driven rack 13 that meshes with the reversing gear 12 and can slide along the track under its rotation. The driven rack 13 is fixed to the other side of the reversing gear 12 by a fork 14 with protective lubricating elements 15 located on the front and rear sides of the cutter 9. When the retractable cutter moves radially toward the center, the two adjacent protective lubricating elements 15 move in opposite directions and rub against the blade to achieve self-lubrication. When the retractable cutter moves away from the center, the two adjacent protective lubricating elements 15 gradually move from the edges of the cutter 9 away from the center toward the blade side to close the blade.

[0042] The driving rack 10 and the driven rack 13 are staggered in two different longitudinal planes to avoid interference between their movements; the reversing gear 12 has a certain axial depth length so that it can mesh and transmit power with both the driving rack 10 and the driven rack 13 simultaneously; the maximum length of the driven rack 13 extending toward the cutter holder 8 does not hinder its radial displacement toward the center; the fork 14 is fixedly installed on the side wall of the driven rack 13, and its bottom end has a forked structure, which is inclined toward the center and fixed to the protective lubricating element 15 parallel to the cutter 9; when the retractable cutter moves radially toward the center to its limit position, the protective lubricating element 15 completely detaches from the surface of the cutter 9; when the retractable cutter moves away from the center to its limit position, the protective lubricating element 15 seals the cutting edge of the cutter 9; Note: The contact trajectory between the protective lubricating element 15 sliding parallel to the track and the radially moving side wall of the cutter 9 is approximately a triangular area;

[0043] The cutter 9 has a triangular cross-section; the protective lubricating component 15 includes a base 151 fixed to the bottom of the fork 14, and an oil reservoir 152 is detachably placed inside the base 151. The oil reservoir 152 is connected to an elastic cotton block 154 located on the side wall of the base 151 through an oil guide core 153, so as to automatically absorb oil to maintain a saturated state; the elastic cotton block 154 is attached to the side wall of the cutter 9 and is squeezed and oil is released as the cutter 9 moves down, thereby improving the continuous lubrication capability.

[0044] Example 3: To ensure that the operator receives timely feedback to stop cutting after the tool has cut a certain thickness of armor layer or insulation layer, thus preventing damage to the internal wire core, refer to... Figures 1 to 2 , Figure 6 and Figure 8 As shown, the device also includes a cutting depth determination system, which includes a power connector mounted above the processing table 1 to abut the cable insertion end, a power terminal mounted in the blade holder 8 and connected to the cutter 9, and a power module and an alarm unit. The power module, alarm unit, power connector, and power terminal are connected in series by wires. The metal cutter 9 acts as a circuit switch. When it cuts the outer layer of the cable and touches the core, a closed circuit is formed, and the alarm unit sounds an alarm to remind the operator to stop the cutting operation. The power module is set to a safe voltage that can be received by the human body, below 12V, to avoid accidental contact and potential safety hazards.

[0045] The cutter holder 8 includes a sleeve 81 fixedly fitted to the shaft end of the cutter holder 7, a receiving cavity 83 opened in the sleeve 81 for placing the electrical terminal, and an end cover 82 detachably installed outside the receiving cavity 83. The end cover 82 is fixed to the cutter 9 on the other side of the receiving cavity 83. One end of the electrical terminal is connected to the cutter 9, and the other end is connected to the circuit via a wire. The side walls of the receiving cavity 83 and the radial groove 41 are provided with wire-passing holes. The cutter holder 7 has a hollow structure, so that the wires led out from the electrical terminal can pass through the receiving cavity 83, the cutter holder 7 and the radial groove 41 in sequence and then be connected to the circuit for wiring. The length of the wire extending out of the wheel 4 can be wound around within a predetermined number of rotations without affecting the cutting of the outer layer of the cable. After the cutting is completed, the wheel 4 is controlled to rotate in the opposite direction and reset in time by the first drive mechanism 3, which can avoid over-winding and thus ensure the stability and reliability of the device operation.

[0046] The working principle of this invention in collaborative operation:

[0047] The cable is passed through the first wire hole 42 and the second wire hole 52 until one end of the cable extends beyond the position of the cutter 9 to meet the predetermined standard for the stripping length of the cable. At this time, the second drive mechanism 6 is controlled to drive the adjusting plate 5 to rotate. When the adjusting plate 5 rotates clockwise (towards...), Figure 5 (The axis direction shown is for reference). The guide groove 51 revolves around the center, applying an inward thrust perpendicular to the guide groove 51 to the end of the tool holder 7. The component of this thrust along the radial groove 41 can pull the tool holder 7 to slide towards the center relative to the wheel 4. At the same time, the contact position between the guide groove 51 and the tool holder 7 changes radially from the outer ring layer to the inner ring layer closer to the center. Before the cutting blade 9 touches the surface of the cable, the first drive mechanism 3 is coordinated to drive the wheel 4 to rotate, so that the second drive mechanism 6, the adjusting plate 5, and the retractable cutting tool rotate together with the wheel 4, thereby causing multiple cutting blades to rotate. 9. The armor or insulation layer of a certain thickness at the end of the cable is stripped using a progressively deeper ring-cutting method. When the adjusting disc 5 rotates counterclockwise, the guide groove 51 revolves around the center in the opposite direction (in the opposite direction to the above), applying an outward thrust perpendicular to the guide groove 51 to the end of the tool holder 7. The component of this thrust along the radial groove 41 can pull the tool holder 7 to slide away from the center relative to the wheel disc 4. At the same time, the contact position between the guide groove 51 and the tool holder 7 changes radially from the inner ring layer to the outer ring layer, causing the retractable tool to gradually retract to the initial position, facilitating the next round of stripping.

[0048] Furthermore, this device is equipped with a coordinated mechanism for blade lubrication and blade retraction protection: when the retracting blade converges towards the center (moving radially towards the center), the drive rack 10 moves radially synchronously and drives the reversing gear 12 to rotate towards the tool holder 8. The driven rack 13, which is not coplanar with the drive rack 10 (misaligned), slides away from the tool holder 8 under the drive of the reversing gear 12, and moves horizontally along with the protective lubricating element 15 via the fork 14. This causes the protective lubricating element 15 covering both sides of the blade to quickly retract from the cutting blade 9 moving radially towards the center. During the relative movement, the cutting blade 9 and the protective lubricating element 15 generate a certain frictional force, thereby protecting their contact surfaces. Lubrication is performed to reduce cutting wear and improve the continuous stripping effect on the armor or insulation layer of the cable end. When the retractable blade expands away from the center (moves away from the center), the drive rack 10 moves radially in the opposite direction and drives the reversing gear 12 to rotate toward the opposite side of the blade holder 8. The driven rack 13, which is not coplanar with the drive rack 10 (misaligned), slides back to the side closer to the blade holder 8 under the drive of the reversing gear 12, and moves horizontally along the protective lubricating element 15 via the fork 14. This causes the protective lubricating element 15 to close along the surface of the cutter 9, which is radially resetting away from the center, until the blade is sealed and protected again, preparing for the next stripping task.

[0049] The above description represents a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, in accordance with the technical plan and improved concept of the present invention, should be included under the protection of the present invention.
