Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, and in particular to an insulation wire stripper and a use method thereof. Background Art

[0002] In the daily work of the power sector, power inspection and maintenance is an important task to ensure people's daily electricity use. At the same time, based on the actual needs of power grid construction, a considerable part of the work in the transformation or construction of the current power system is for insulated wires, such as installing grounding rings on insulated wires, stripping the wires on the cables and connecting them or connecting them to related equipment. Since the insulated wires or cables are energized, the power outage operation process is complicated and requires multiple levels of approval. Generally, live operations are used to complete related operations.

[0003] At present, in the wire stripping process of insulated wires, since the diameters of insulated wires of different grades are different and the specifications of the wire strippers required are also different, power maintenance personnel mainly use wire strippers to complete the corresponding wire stripping work. When using the wire strippers, the operator needs to be in a position close to the conductive insulated wire, which poses certain safety hazards. At this time, the operator needs to wear insulating equipment to protect his own work safety. Wearing insulating equipment requires many steps, which is not convenient for the operator to climb, and seriously affects the work efficiency. At the same time, the use of traditional wire strippers is close to the operator's hands, which is easy to scratch the operator's hands, posing a safety hazard.

[0004] In order to overcome the above problems, the Chinese invention patent with application number 201710587237.8 discloses an insulated wire stripper and a method of use. The technical solution proposes an insulated wire stripper, which includes a base and a knife seat. The base includes a first bottom plate and a second bottom plate. The first groove and the third groove are parallel and the axes coincide with each other. The second groove and the fourth groove are parallel and the axes coincide with each other. The first adjustment mechanism drives the first bottom plate to move, and the second adjustment mechanism drives the second bottom plate to move. The knife seat is provided with a fifth groove and a sixth groove. A straight knife is arranged in the fifth groove, and an oblique knife is arranged in the sixth groove. The third adjustment mechanism can drive the straight knife and the oblique knife to move up and down at the same time. One end of the base is hinged to one end of the knife seat. The insulated wire stripper in this solution can increase the speed of stripping the insulation layer, is easy and quick to operate, avoids scratching the inner core of the wire or scratching the arm of the person, saves time and effort, and this solution can adapt to insulated wires of different diameters, is flexible to adjust, and improves efficiency.

[0056] like Figures 1 to 10 As shown, it shows a specific embodiment of the present invention.

[0057] Embodiment 1

[0058] The present invention discloses an insulating wire stripper, comprising a wire stripper housing 1, a V-shaped baffle plate 2, an insulating operating rod 3, a cutter assembly 4, a cutter operating mechanism 5, a ring cutting assembly 6, a ring cutting operating mechanism 7, and a housing rotating operating mechanism 8. The upper end of the wire stripper housing 1 is a hollow structure, and the lower end is an arc-shaped structure. The V-shaped baffle plate 2 is rotatably connected to the bottom of the wire stripper housing 1, and the insulating operating rod 3 is rotatably connected to the right side of the wire stripper housing 1. The cutter assembly 4 and the ring cutting assembly 6 are installed in the hollow structure of the wire stripper housing 1. The ring cutting operating mechanism 7 is connected to the ring cutting assembly 6 and is located on the right side of the insulating operating rod 3. The cutter operating mechanism 5 is connected to the cutter assembly 4 and is located inside the insulating operating rod 3. The housing rotating operating mechanism 8 is located on the left side of the insulating operating rod 3.

[0059] In this embodiment, Figure 1 , Figure 2 As shown, the insulated wire stripper fixes the position of the wire to be stripped by a V-shaped baffle 2 to ensure the reliable operation of the wire stripper, and uses the insulating operating rod 3 to control the corresponding operating mechanism to realize the stripping of the insulated wire skin at the stripping position. During the whole process, the operator always maintains a safe working distance from the stripping position of the live wire, that is, the length of the insulating operating rod 3, and its length is the safety distance in the power operation regulations to ensure the safety of the operator. The cutter operating mechanism 5 and the ring cutting operating mechanism 7 control the stripping depth, which is suitable for live wires of different voltage levels and has a wide range of applications. After the stripping depth is determined, the shell rotation operating mechanism 8 is used to control the rotation of the wire stripper shell to realize the stripping of the insulated live wire skin. The wire stripper has a simple overall structure and is easy to operate. At the same time, a safe operating distance is reserved to ensure operation safety.

[0060] A limit strip 11 is designed at the lower right end of the arc-shaped structure below the wire stripper housing 1, and a cutting slit 12 is opened in the middle of the wire stripper housing 1;

[0061] In this embodiment, Figure 7 As shown, the limiting strip 11 is used to limit the V-shaped baffle 2, and the cutting slit 12 is used for the up and down movement of the cutting knife 41 in the cutting knife assembly 4 to realize the stripping of the wire sheath of the insulated wire to be stripped.

[0062] Specifically, the V-shaped baffle 2 includes a first baffle 21 and a second baffle 22. One side of the first baffle 21 is rotatably connected to the left side below the wire stripper housing 1, and one side of the second baffle 22 is rotatably connected to the other side of the first baffle 21. The other side of the second baffle 22 is located above the limit bar 11 of the arc-shaped structure of the wire stripper housing 1.

[0063] In this embodiment, Figure 8 As shown, one side of the first baffle 21 is rotatably connected to the left position below the wire stripper housing 1, and one side of the second baffle 22 is rotatably connected to the other side of the first baffle 21, and the other side of the second baffle 22 is located above the limit bar 11 of the arc-shaped structure of the wire stripper housing 1. When in use, the second baffle 22 is pressed against the insulated wire, and the second baffle 22 rotates around the first baffle 21, and then the first baffle 21 is rotated outward, so that the insulated wire is embedded in the arc-shaped structure below the wire stripper housing 1. The second baffle 22 of the wire stripper housing 1 is operated to be located above the limit bar 11 under the action of gravity, so that the position of the insulated wire is fixed, and the operation is simple and convenient.

[0064] A first pulley 13 and a second pulley 14 are fixedly installed in the hollow structure of the wire stripper housing 1. The first pulley 13 and the second pulley 14 are installed below the top surface of the hollow structure. The first pulley 13 is located above the hook, and the second pulley 14 is located near one end of the insulating operating rod 3.

[0065] The upper end and the interior of the insulating operating rod 3 are hollow structures. A third pulley 31 is fixedly mounted on the upper end of the insulating operating rod 3 . A rotating operating hole 32 , a ring cutting operating hole 33 , and a cutter operating hole 34 are opened on the lower surface of the insulating operating rod 3 .

[0066] In this embodiment, Figure 3As shown, the first pulley 13, the second pulley 14, and the third pulley 31 are fixed by a pulley fixing block and are all installed in the top hollow structure of the insulation stripper. The first pulley 13, the second pulley 14, and the third pulley 31 can change the direction of the insulation rope 64 on the hook 43 of the cutter assembly 4, so as to realize the adjustment of the cutting depth of the cutter 41 on the cutter assembly 4 through the cutter operating mechanism 5, and the position of the cutter operating mechanism 5 is controlled at the lower end of the insulation operating rod 3, so that the insulation rope 64 is subjected to tension in different directions, and the depth of the cutter 41 is adjusted to be suitable for insulated wires with different stripping depths.

[0067] In this embodiment, Figure 4 , Figure 5 As shown, the rotating operating hole 32, the circular cutting operating hole 33, and the cutter operating hole 34 are arranged on the lower surface of the insulating operating rod 3, so that the operator who actually performs the wire stripping operation has a certain safety distance from the live insulated wire during the operation, and operates the corresponding operating mechanisms in the rotating operating hole 32, the circular cutting operating hole 33, and the cutter operating hole 34 to achieve wire stripping, thereby ensuring the operator's operating safety and reducing safety risks.

[0068] Specifically, the ring cutting assembly 6 includes a left ring cutting knife 61, a right ring cutting knife 62, an adjustment screw 63, and an insulating rope 64. The left ring cutting knife 61 is located on the left side of the wire stripper housing 1, and the right ring cutting knife 62 is located on the right side of the wire stripper housing 1. The inner sides of the left ring cutting knife 61 and the right ring cutting knife 62 are connected to the insulating rope 64, and the insulating rope 64 is wound around the adjustment screw 63. The adjustment screw 63 is connected to the ring cutting operating mechanism 7.

[0069] Specifically, two groups of wire collecting grooves in opposite directions are arranged on the adjusting screw rod 63 , and the wire collecting grooves in the same direction of the two groups of wire collecting grooves connect the same side cutters of the left ring cutter 61 and the right ring cutter 62 .

[0070] In this embodiment, Figure 3 As shown, the left ring cutter 61 and the right ring cutter 62 are respectively located at the two ends of the insulated wire to be stripped, and the left ring cutter 61 and the right ring cutter 62 are connected by an adjusting screw 63. The insulating rope 64 is connected to the inner side of the left ring cutter 61 and the right ring cutter 62. When the adjusting screw 63 rotates under the action of the ring cutting operating mechanism 7, the insulating rope 64 on the adjusting screw 63 shrinks or expands in the wire collecting groove. When shrinking, the position where the lower ends of the left ring cutter 61 and the right ring cutter 62 are clamped on the insulated wire also shrinks, cutting a certain depth to achieve stripping on both sides of the wire to be stripped. When expanding, the position where the lower ends of the left ring cutter 61 and the right ring cutter 62 are clamped on the insulated wire also expands, and the left ring cutter 61 and the right ring cutter 62 are away from the live insulated wire to avoid damage to the wire core and ensure the stripping quality.

[0071] In this embodiment, during actual use, since two sets of wire collecting grooves in opposite directions are arranged on the adjusting screw 63, the left ring cutter 61 and the right ring cutter 62 remain straight when contracted or expanded, and the adjusting screw 63 rotates to drive the wire collecting groove to rotate, so that the insulating rope 64 in the wire collecting groove is collected or released on the adjusting screw 63, and the other end of the insulating rope 64 is fixed to the inner side of the corresponding left ring cutter 61 or the right ring cutter 62, so that the insulating rope 64 provides tension to the left ring cutter 61 and the right ring cutter 62, thereby realizing the removal of the outer skin of the insulated wire at both ends of the insulated wire. At this time, the two ends have been cut off, and the removal in the longitudinal position is realized.

[0072] In this embodiment, Figure 3 As shown, the adjusting screw 63 is located above the hook 43 that cuts into the component 4. Since an insulating rope 64 is connected above the hook 43, a through hole is opened at the position where the adjusting screw 63 is located above the hook 43, which is convenient for fixing the insulating rope 64 above the hook 43 and avoids affecting the movement of the adjusting screw 63, so that the insulating wire stripper can work reliably and effectively.

[0073] Specifically, the circular cutting operation mechanism 7 includes an upper worm wheel 71, a worm 72, a lower worm wheel 73, and a handle 74. The upper worm wheel 71 is rotatably connected to the right side of the adjustment screw 63. The upper end of the worm 72 cooperates with the upper worm wheel 71, and the lower end cooperates with the lower worm wheel 73. The handle 74 is connected to the lower worm wheel 73 and is located in the circular cutting operation hole 33.

[0074] In this embodiment, Fig. 9 As shown, the ring cutting operating mechanism 7 adopts the principle of worm gears to transmit the rotation of the handle 74 at the bottom end of the insulating operating rod 3 to the rotation of the adjusting screw 63 at the top. The handle 74 is turned, and the handle is connected to the lower worm wheel 73. The rotation of the handle 74 causes the rotation of the lower worm wheel 73, thereby the lower worm wheel 73 rotates, driving the rotation of the worm 72. At the same time, the upper worm wheel 71 above the worm 72 also rotates under the rotation of the worm 72. The rotation of the upper worm wheel 71 causes the rotation of the adjusting screw 63 connected to its left side, thereby adjusting the cutting depth of the ring cutting assembly 6 and cutting in or removing the left ring cutting knife 61 and the right ring cutting knife 62 by rotating the handle 74.

[0075] Specifically, the cutter assembly 4 includes a cutter 41, a pressure block 42, a hook 43, and an insulating rope 64. The cutter 41 is fixed at a middle position below the pressure block 42. The pressure block 42 is placed on the bottom surface of the hollow structure of the wire stripper housing 1. The cutter 41 is located in the cutter slit 12. The hook 43 is fixed at a middle upper surface position of the pressure block 42. The insulating rope 64 is connected to the hook 43.

[0076] In this embodiment, Figure 3As shown, the cutter 41 is fixed at the middle position below the pressure block 42, and the pressure block 42 is placed on the bottom surface of the hollow structure of the wire stripper housing 1. The cutter 41 is located in the cutter slit 12. The cutter 41 moves downward a certain distance in the cutter slit 12 under the gravity of the pressure block 42. The hook 43 is fixed on the middle upper surface of the pressure block 42, and the insulating rope 64 is connected to the hook 43. The end of the insulating rope 64 is connected to the cutter operating mechanism 5, which controls the position of the insulating rope collecting rod 51 of the cutter operating mechanism 5 in the cutter operating hole 34, changes the distance of the cutter 41 in the cutter slit 12, and realizes the adjustment of the wire stripping depth. It is suitable for charged insulated wires or cables of different diameters.

[0077] The middle of the worm 72 is a hollow structure, and a lead-out hole is opened below the worm 72. A fourth pulley is installed on the upper surface of the lead-out hole.

[0078] One end of the insulating rope 64 is fixedly connected to the hook 43, and the other end passes through the first pulley 13, the second pulley 14, and the third pulley 31 in sequence, then passes through the inside of the worm 72, passes through the fourth pulley, and exits from the lead-out hole to be connected to the cutter operating mechanism 5.

[0079] In this embodiment, the insulating rope 64 on the hook 43 changes the direction of force through the first pulley 13, the second pulley 14, and the third pulley 31, passes through the inside of the worm 72, and then passes through the lead-out hole at the lower end of the worm 72 through the fourth pulley, and is finally connected to the cutter operating mechanism 5. The tension on the hook 43 is adjusted by adjusting the cutter operating mechanism 5, thereby adjusting the cutting depth of the cutter 41, which is suitable for different stripping depths required for insulated wires of different voltage levels.

[0080] Specifically, the cutter operating mechanism 5 includes an insulating rope collecting rod 51 and a limiting plate 52. One end of the insulating rope collecting rod 51 is fixedly connected to the limiting plate 52. The limiting plate 52 is installed in the cutter operating hole 34. The other end of the insulating collecting rod 51 is connected to the insulating rope 44 passing through the lead-out hole.

[0081] In this embodiment, Figure 6 As shown, the insulating rope collecting rod 51 is connected to the insulating rope 64 cut to the component 4. When the cutting depth of the cutter 41 on the insulated wire needs to be adjusted, the position of the insulating collecting rod 51 in the cutter operating hole 34 is adjusted and fixed by the limiting plate 52.

[0082] Specifically, a rotating column 15 is fixedly designed at the right end of the wire stripper housing 1, and the housing rotating operating mechanism 8 is connected to the rotating column 15. The housing rotating operating mechanism 8 includes a rotating upper worm gear 81, a rotating worm 82, a rotating lower worm gear 83, and a rotating handle 84. The rotating upper worm gear 81 is fixedly connected to the right side of the rotating column 15, the upper end of the rotating worm 82 cooperates with the rotating upper worm gear 81, and the lower end cooperates with the rotating lower worm gear 83. The rotating handle 84 is connected to the rotating lower worm gear 83 and is located in the rotating operating hole 32.

[0083] In this embodiment, Fig. 9 As shown, since the rotating column 15 is fixed on the right side of the wire stripper housing 1, the rotation of the rotating column 15 is used to realize the rotation of the entire wire stripper, and the rotation of the rotating handle 84 at the bottom end of the insulating operating rod 3 is transmitted to the rotation of the rotating column 15 at the top. The rotating handle 84 is rotated, and the rotating handle 84 is rotatably connected to the rotating lower worm gear 83. The rotation of the rotating handle 84 causes the rotation of the rotating lower worm gear 83, thereby rotating the rotating lower worm gear 83, driving the rotation of the rotating worm 82, and at the same time, the rotating upper worm gear 81 above the rotating worm gear 82 also rotates under the rotation of the rotating worm gear 82. The rotation of the rotating upper worm gear 81 causes the rotation of the rotating column 15 connected to its left side, thereby realizing the rotation of the entire wire stripper by rotating the rotating handle 84 to complete the wire stripping.

[0084] Specifically, the insulating rope 64 is a steel wire insulating rope.

[0085] In this embodiment, the use of steel wire insulation rope can ensure the provision of reliable and effective pulling force. The steel wire insulation rope itself is strong, wear-resistant, durable, and has a long service life, thereby ensuring the service life of the insulation stripper.
