Description

Technical Field

[0001] This invention relates to the field of wire stripper technology, and in particular to an electric wire stripper capable of operating under live conditions. Background Technology

[0002] In the construction, inspection and maintenance of power systems, conductor stripping is a fundamental and frequent operation. Its quality and efficiency directly affect the stability of the power supply system and the construction progress. With the rapid development of the social economy, various industries have increasingly higher requirements for the continuity of power supply.

[0003] However, while existing electric wire stripping equipment reduces manual labor intensity to some extent, it has significant shortcomings in safety design. Most equipment lacks effective enclosure and isolation structures, making it susceptible to accidental displacement of conductors during operation due to equipment vibration, external interference, etc., leading to exposure of live parts and posing a risk of contact. Furthermore, existing electric wire stripping equipment often requires manual assistance to adjust conductor positioning or connect different work steps, resulting in prolonged stripping time for a single conductor. In large-scale line construction or emergency repair scenarios, it is difficult to effectively improve work efficiency, and may even delay power restoration progress due to excessively long operation times, causing significant economic losses and social impact.

[0028] Figures 1-7An embodiment of this application illustrates an electric wire stripper capable of live-line operation. The electric wire stripper provided in this embodiment includes two stripping modules 1 symmetrically distributed about the axis of the electric wire stripper. The two stripping modules 1 are rotatable to achieve separation and merging of the two stripping modules 1. Figure 1 and Figure 2 As shown, the bottom ends of the two peeling modules 1 are rotatably connected by connecting parts 2, and the top ends of the two peeling modules are connected by engaging parts 3. The connecting parts 2 include, but are not limited to, hinge connectors, pivot connectors, and bearing connectors; the engaging parts 3 include, but are not limited to, snap fasteners, clamps, snap rings, and quick-release pins. In this embodiment, the connecting parts 2 are hinge connectors, and the engaging parts 3 are snap fasteners.

[0029] The stripping module 1 includes: an outer shell 10, an inner shell 11 matching the shape of the outer shell 10, a cutting and stripping module, and an insulating gas source 4. The outer shell 10 has an arc-shaped port 12 at its end to facilitate the insertion of wires into the module. The inner shell 11 is installed inside the outer shell 10, and its end also has an arc-shaped port 12, with the end of the inner shell 11 sealed to the end of the outer shell 10. The cutting and stripping module is mounted on the inner shell 11 and is used to cut and strip the wire sheath. When two stripping modules 1 are combined, the arc-shaped ports 12 and the inner shell 11 of the two stripping modules 1 are interconnected to form a cutting chamber 13. Preferably, both the outer shell 10 and the inner shell 11 have high-temperature resistant sealing gaskets on their end faces to improve the sealing between the two stripping modules 1.

[0030] The insulating gas source 4 is disposed between the inner wall of the outer casing 10 and the outer wall of the inner casing 11, such as... Figure 3 As shown, the insulating gas source 4 stores insulating gas. In this embodiment, the insulating gas is sulfur hexafluoride. The output port 15 of the insulating gas source 4 extends into the interior of the inner housing 11. Furthermore, a control valve 16 is provided on the output port 15 of the insulating gas source 4 to control the opening and closing of the output end of the insulating gas source 4. When the two stripping modules 1 are combined, the control valve 16 opens the output port 15 of the insulating gas source 4 to introduce insulating gas into the cutting chamber 13, preventing residual electrical charge on the wires from harming the workers.

[0031] The cutting and peeling module includes a moving component 43, a cutting component, and a peeling component. The moving component 43 is capable of reciprocating radially along the inner housing 11; the cutting component is mounted on the moving component 43 and is capable of reciprocating axially along the inner housing 11, and is used to perform circumferential cutting on the wire sheath; the peeling component is mounted on the moving component 43 and is capable of reciprocating axially and vertically along the inner housing 11, and the second cutting blade 41 is used to perform lateral axial cutting and peeling on the wire sheath.

[0032] Combination Figure 4 and Figure 5 The moving assembly 43 includes: a moving plate 21 and a first electrically operated telescopic rod 22. The moving plate 21 is disposed within the inner housing 11 along the axial direction of the inner housing 11; the fixed end of the first electrically operated telescopic rod 22 is fixed to the inner sidewall of the inner housing 11, and the moving end of the first electrically operated telescopic rod 22 is fixed to the moving plate 21, for driving the moving plate 21 to reciprocate radially along the inner housing 11. Figure 5 As shown, the two ends of the movable plate 21 are respectively provided with limiting blocks 23, and the two inner sidewalls of the inner shell 11 that are perpendicular to the movable plate 21 are respectively provided with sliding grooves 14 corresponding to the limiting blocks 23, and the limiting blocks 23 are slidably connected in the sliding grooves 14.

[0033] The side walls at both ends of the movable plate 21 are respectively provided with support plates extending radially toward the inner shell 11, referred to as the first support plate 24 and the second support plate 25.

[0034] Combination Figure 4 and Figure 6 The cutting assembly includes: a first cutting blade 31, two first lead screw drive mechanisms 32, and two moving blocks 33. The first cutting blade 31 is arc-shaped; preferably, the first cutting blades 31 in the two peeling modules 1 are staggered to cut the circumferential wall of the wire. The two moving blocks 33 are slidably connected to the moving plate 21, and the ends of both moving blocks 33 are fixedly connected to the first cutting blade 31.

[0035] The two first lead screw drive mechanisms 32 are symmetrically distributed about the axis of the moving plate 21. Each first lead screw drive mechanism 32 includes a first drive motor 321 and a first lead screw 322. Figure 4As shown, the first drive motor 321 is fixed on the first support plate 24, and the output end of the first drive motor 321 passes through the first support plate 24; the first end of the first lead screw 322 is rotatably connected to the second support plate 25, and the second end of the first lead screw 322 is fixedly connected to the output end of the first drive motor 321. Two moving blocks 33 are threadedly connected to the two first lead screws 322 respectively. The first lead screw 322 drives the moving blocks 33 to reciprocate along the axial direction of the inner housing 11 by rotating, thereby driving the first cutting blade 31 to reciprocate along the axial direction of the inner housing 11, so as to adjust the cutting and peeling length of the wire sheath as needed.

[0036] The side wall of the movable plate 21 is also provided with two sliding grooves 26, the positions of the two sliding grooves 26 corresponding one-to-one with the positions of the two movable blocks 33. The sliding grooves 26 are located between the two support plates, and the size of the sliding grooves 26 matches the size of the end of the movable plate 21. The ends of the two movable blocks 33 away from the first cutting blade 31 are slidably connected to the two sliding grooves 26 respectively.

[0037] Combination Figure 4 and Figure 7 The stripping assembly includes a second cutting blade 41, a connecting block 42, two moving components 43, and a second lead screw drive mechanism 44. The second cutting blade 41 is disposed on the side of the first cutting blade 31 away from the arc-shaped port 12. Preferably, the two second cutting blades 41 in the two stripping modules 1 are arranged opposite to each other. The second cutting blade 41 includes two cutting blades 411, and the sidewalls of the two cutting blades 411 can contact each other so that the cutting edges of the two cutting blades 411 can be inserted into the outer sheath of the wire simultaneously.

[0038] The connecting block 42 is slidably connected to the moving plate 21, and each of the two ends of the connecting block 42 in the height direction is provided with an extension plate 45 extending radially toward the inner housing 11. The two moving components 43 are arranged opposite to each other, and the two moving components 43 are respectively connected to the two extension plates 45 one-to-one, and the two moving components 43 are respectively connected to the back of the two cutting blades 411 one-to-one. The moving components 43 are used to control the cutting blades to move up and down along the height direction of the inner housing 11.

[0039] like Figure 7As shown, the moving component 43 includes a second electric telescopic rod 431 and a fixing plate 432. The fixed end of the second electric telescopic rod 431 is fixed to the extension plate 45, and the moving end of the second electric telescopic rod 431 extends through the extension plate 45 to another moving component 43 disposed opposite to it. The first end of the fixing plate 432 is fixedly connected to the moving end of the second electric telescopic rod 431, and the second end of the fixing plate 432 is fixedly connected to the back of the cutting blade 411. The second electric telescopic rod 431 drives the fixing plate 432 to reciprocate up and down along the height direction of the inner housing 11, thereby driving the cutting blade 411 to reciprocate up and down along the height direction of the inner housing 11. Specifically, when the cutting blade 411 inserts into the outer sheath of the wire and completes the cutting work, the upper electric telescopic rod 431 and the lower electric telescopic rod 431 operate synchronously, causing the upper electric telescopic rod 431 to drive the connected cutting blade 411 to move upward and the lower electric telescopic rod 431 to drive the connected cutting blade 411 to move downward, thereby causing the two contacting cutting blades 411 to separate from each other, thereby pulling the outer sheath of the wire up and down to achieve the purpose of stripping the outer sheath of the wire.

[0040] The second lead screw drive mechanism 44 includes a second drive motor 441 and a second lead screw 442. The second drive motor 441 is fixed on the first support plate 24, and its output end passes through the first support plate 24. The first end of the second lead screw 442 is rotatably connected to the second support plate 25, and its second end is fixedly connected to the output end of the first drive motor 321. The connecting block 42 is threaded onto the second lead screw 442. The second lead screw 442 drive assembly is used to drive the connecting block 42 to reciprocate along the axial direction of the inner housing 11, thereby driving the cutting blade to reciprocate along the axial direction of the inner housing 11 to cut the outer sheath of the wire.

[0041] Two limiting rods 46 are slidably connected to the connecting block 42. The limiting rods 46 are fixed between the first support plate 24 and the second support plate 25, and the two limiting rods 46 are symmetrically distributed about the second lead screw 442. This arrangement allows the limiting rods 46 to limit and guide the connecting block 42, ensuring that the connecting block 42 moves linearly along the second lead screw 442, thereby ensuring that the cutting blade 411 moves linearly along the axial direction of the inner housing 11, and thus improving the flatness of the cut on the side of the wire sheath.

[0042] The live-line working electric wire stripper further includes a control module (not shown in the figure), which is connected to the control valve 16, the first electric telescopic rod 22, the first drive motor 321, the second drive motor 441, and the second electric telescopic rod 431. The control module controls the opening of the output port 15 of the insulating gas source 4 by controlling the control valve 16, thereby introducing insulating gas into the cutting chamber 13; and controls the movement of the moving plate 21 along the radial direction of the inner shell 11 by controlling the first electric telescopic rod 22. The positions of the first cutting blade 31 and the second cutting blade 41 are adjusted accordingly. The first cutting blade 31 is moved axially along the inner housing 11 by controlling the first drive motor 321, thereby adjusting the cutting and peeling length of the wire sheath. The second cutting blade 41 is moved axially along the inner housing 11 by controlling the second drive motor 441, thereby cutting the side of the wire sheath. The cutting blade 411 is moved up and down along the height direction of the inner housing 11 by controlling the second electric telescopic rod 431, thereby peeling off the wire sheath.

[0043] Working principle: The operator operates the latches at the top of the two stripping modules 1 to disengage them. At this point, the two stripping modules 1 rotate relative to each other around the hinge connector, and the cutting chamber 13 opens accordingly. The operator places the live wire to be stripped into the inner shell 11 inside the cutting chamber 13, then rotates the stripping modules 1 in the opposite direction to reconnect and close the ports of the two stripping modules 1, and finally tightens the latches to complete the initial fixation of the equipment and the wire.

[0044] To prevent residual electrical charge on the conductors from harming workers after live-line work, the power to the conductors is switched off, and the ends of the two stripping modules 1 are connected. Then, control valve 16 is activated to open the output of the insulating gas generator, allowing insulating gas to enter the inner housing 11 and fill the work space. Utilizing the insulating properties of sulfur hexafluoride to isolate residual electrical charge ensures the safety of workers during conductor stripping, guaranteeing the safety of live-line work and effectively improving the efficiency and safety of conductor stripping.

[0045] After the wires are fixed, the control module controls the first drive motor 321 and the second drive motor 441 to operate synchronously to adjust the positions of the first cutting blade 31 and the second cutting blade 41. Specifically, the first drive motor 321 and the second drive motor 441 start after receiving the control signal, driving the first lead screw 322 and the second lead screw 442 to rotate in both directions. Since the moving block 33 is threadedly connected to the first lead screw 322 and the connecting block 42 is threadedly connected to the second lead screw 442, and the moving block 33 is slidably connected in the sliding groove 26 on the side wall of the moving plate 21, and the connecting block 42 is slidably connected to the limiting rod 46, the rotation of the first lead screw 322 is converted into the linear movement of the moving block 33 along the sliding groove 26, and the rotation of the second lead screw 442 is converted into the linear movement of the connecting block 42 along the limiting rod 46, thereby making the first cutting blade 31 and the second cutting blade 41 move synchronously.

[0046] When the first cutting blade 31 and the second cutting blade 41 move to the target position, the first electric telescopic rod 22 is activated. The moving end of the first electric telescopic rod 22 drives the moving plate 21 and the first cutting blade 31 and the second cutting blade 41 on it to move towards the wire. At this time, the first cutting blade 31 and the second cutting blade 41 in the two stripping modules 1 move towards each other. When the first cutting blade 31 and the second cutting blade 41 move to contact the circumferential wall of the wire and reach the preset cutting depth, the second electric telescopic rod 431 stops, completing the circumferential cutting of the wire sheath, laying the foundation for subsequent side cutting and sheath peeling.

[0047] The second drive motor 441 is started, and its output drives the second lead screw 442 to rotate. The connecting block 42 is threaded onto the second lead screw 442, and under the limiting action of the limiting rod 46, the rotation of the second lead screw 442 is converted into the horizontal linear movement of the connecting block 42 along the axial direction of the inner shell 11. This, in turn, drives the second cutting blade 41 to move along the axial direction of the wire, completing the axial cutting of the wire sheath side and forming a cutting seam connected to the circumferential cutting of the wire sheath. The two second electric telescopic rods 431 are started to operate synchronously. The moving ends of the two second electric telescopic rods 431 pull their respective fixed plates 432 and cutting blades 411 to move in opposite directions, so that the two cutting blades 411 pull the cut on the side of the wire sheath to both sides. Combined with the cut formed by the circumferential cutting, the wire sheath is completely separated from the wire core, completing the stripping operation.

[0048] This invention features two symmetrically distributed, relatively rotatable wire stripping modules. When the two modules are separated, the wire is placed into an electric wire stripper for stripping. The two modules are then combined to provide a closed working space for wire stripping, isolating the live wire from the external environment and preventing contact risks caused by accidental wire displacement during operation. Furthermore, this invention releases insulating gas into the closed working space during wire stripping, completely isolating any residual charge on the wire and eliminating safety hazards associated with live work. This ensures personnel safety and improves power supply continuity. In addition, the cutting and stripping module of this invention automatically cuts and strips the wire sheath without manual force. Through coordinated operation with an electronic control system, the stripping time for a single wire is significantly reduced, making it particularly suitable for large-scale line construction or emergency repair scenarios, and significantly improving overall work efficiency.
