Description

  The present invention relates to a tool used for a binding operation for fixing an electric wire to an insulator, and in particular, a bind winding used for a binding winding operation configured to hold the electric wire by winding the electric wire. Concerning ingredients.

  Conventionally, a binding is used to fix an electric wire to an insulator attached to a support such as a utility pole or a steel tower. Such a binding is formed by bending a metal wire with an insulation coating, and generally, an insulator mounting portion formed so as to be attachable to the insulator, and extended from the insulator mounting portion so as to be wound around an electric wire. An electric wire winding portion (see, for example, Patent Document 1).

  The said insulator attachment part is formed in C shape, U shape, or cyclic | annular form so that it can fit in the constriction part formed in the insulator. On the other hand, the wire winding portion extends straight or spirally on both sides with the insulator mounting portion at the center.

  The bind having the above-described configuration can fix the electric wire to the insulator by attaching the insulator attaching portion to the insulator and winding the wire winding portion around the electric wire.

  By the way, in recent years, from the viewpoint of ensuring the safety of workers, work on the power distribution system and the like is performed by indirect hot-line work in which the workers do not directly touch the electric wires. That is, a tool corresponding to the work content (hereinafter referred to as a tip tool) is attached to the tip of an insulating operation rod such as a hot stick, and various operations are performed by operating the insulation operation rod.

  Therefore, the above-described binding attachment work (attachment of the insulator attachment portion to the insulator and winding operation of the electric wire winding portion to the electric wire) is also performed by indirect hot wire work. In other words, the insulator mounting portion is attached to the insulator using an insulating yoke or the like, and the electric wire winding portion is wound around the electric wire by operating the insulating operation rod connected with the annular or hook-shaped tip tool (for example, Patent Document 1 and 2).

Specifically, the bind insulator attachment portion held by the insulating yoke is attached (fitted) to the insulator, and the wire winding portion is extended from the insulator (insulator attachment portion). After that, by operating the insulation operating rod with the tip tool hooked on the wire winding part, wind the wire winding part around the wire once and then hook the tip tool on the tip side of the wire winding part. Then, the work of winding the wire winding portion around the wire once again is repeated. That is, since the operation of the insulation operating rod is performed on the side or the lower side of the electric wire, the operation of hooking the tip tool on the electric wire winding portion to spirally wind the electric wire winding portion on the electric wire, By repeating the work of winding the wire winding part on which the tool is hooked around the electric wire and the work of releasing the hook of the tip tool on the wire winding part, the entire length of the wire winding part is wound around the electric wire.

  However, in the conventional binding attachment method, as described above, since the work of re-hooking the tip tool has to be repeated every time the wire winding part is wound around the wire, there is a problem that the work load on the operator is heavy. There is. That is, since the binding is made of an elastic and rigid metal wire, the tip tool is sandwiched between the wire and the binding when the hook of the tip tool is released from the wire winding portion. In some cases, the hook cannot be released smoothly. Therefore, repeatedly performing the work of hooking the tip tool on the wire winding part, the work of winding the wire winding part on which the tip tool is hooked on the electric wire, and the work of releasing the hook of the tip tool on the wire winding part, There is a problem that the work burden on the worker is large and the work efficiency is lowered.

  Then, this invention makes it a subject to provide the binding winding tool which can wind a binding efficiently around an electric wire by simple operation | work in view of such a situation.

  A bind wrapping tool according to the present invention uses a bind provided with an insulator attachment portion formed so as to be attachable to an insulator and an electric wire winding portion extended from the insulator attachment portion so as to be able to be wound around an electric wire. A binding wrapping tool used to wind the wire winding portion around the wire when fixing the wire, and an interposition portion is formed between the wire in parallel and the wire winding portion. A winding tool body is provided, and the winding tool body has a first abutting portion that abuts against the electric wire formed at one end of the interposition portion, and a second abutting portion that abuts the electric wire winding portion. It is formed in the other end of a part.

  According to the bind wrapping tool having the above-described configuration, the interposed part is disposed between the electric wire in the parallel state and the wire wrapping part, and the wrapping tool main body is moved while the first contact part is in contact with the outer periphery of the electric wire. When rotating around the electric wire, the electric wire winding portion is pushed in the same direction as the rotation direction of the winding tool main body by the second abutting portion and wound around the electric wire one after another.

  At this time, the winding tool main body is pushed and moved in the axial direction of the electric wire by winding the electric wire winding portion, and the electric wire winding portion is wound spirally around the electric wire.

  As described above, the bind wrapping tool according to the present invention is a simple work such as rotating the wrapping tool body around the electric wire without requiring skill in the work, and the electric wire wrapping part with respect to the electric wire. Can be wound continuously.

  As one aspect of the present invention, the winding tool main body is formed in a rod shape or a strip shape with one direction as a longitudinal direction, and a through-hole through which the wire winding portion is inserted penetrates in a direction perpendicular to the longitudinal direction. The intermediate portion is formed between the outer surface of the winding tool body and the inner periphery defining the through hole, and the first contact portion is formed of the outer surface of the winding tool body, A 2nd contact part may be comprised by the inner periphery of a through-hole. In this way, when the wire winding part is wound around the electric wire, that is, when the winding tool body is rotated around the electric wire, the wire winding part and the winding tool body should be integrated. Therefore, the electric wire winding part can be wound around the electric wire only by rotating the winding tool main body without worrying about the posture of the electric wire winding part to be wound.

  In this case, it is preferable that the said through-hole is formed in the approximate center part of the longitudinal direction of a winding tool main body. In this way, the winding tool body can be smoothly rotated with a uniform force regardless of which end of the winding tool body is the power point.

  Further, as another aspect of the present invention, an annular body may be continuously provided at at least one end of the winding tool body. If it does in this way, a winding tool main body can be rotated around an electric wire only by hooking the hook (tip tool) attached to the tip of the insulation operation rod to the annular body, and simply pulling the insulation operation rod.

  As described above, according to the bind wrapping tool according to the present invention, it is possible to achieve an excellent effect that the bind can be efficiently wound around the electric wire by a simple operation.

  Hereinafter, a bind wrapping tool according to a first embodiment of the present invention will be described with reference to the accompanying drawings. The bind wrapping tool according to the present embodiment is used when an electric wire is fixed to an insulator using a bind. That is, the bind wrapping tool according to the present embodiment is used to wind a bind (a wire wrapping portion described later) around an electric wire.

  Here, prior to the description of the binding wrapping tool, the insulator and the binding, which are the premise for using the binding wrapping tool, will be described with reference to FIGS. 1 (a) and 1 (b).

  The insulator 100 is generally attached to a brace (not shown) or the like extending in the lateral direction from a support (not shown) such as a utility pole or a steel tower. The insulator 100 includes an insulating portion 101 having electrical insulation and a leg portion 102 connected to the insulating portion 101. The insulating portion 101 is formed in a cylindrical shape with porcelain, resin, or the like, and a constricted portion 103 is formed over the entire circumference with respect to a predetermined position on the outer circumference. On the other hand, the leg portion 102 is made of a metal bar and extends downward from the lower end of the insulating portion 101. The leg portion 102 is provided with a screw (not shown) at the lower end portion, so that the leg portion 102 can be fixed to a bracelet or the like.

  The bind 200 is formed by bending a metal wire (for example, spring steel) coated with insulation, and is formed on an insulator mounting portion 201 that can be attached to the insulator 100 and an electric wire C. Wire winding portions 202a and 202b extending from the insulator mounting portion 201 so as to be wound are provided. The lever mounting portion 201 is generally formed in a U shape, a C shape, or an annular shape, and is formed so as to be fitted to a constricted portion 103 formed in the lever 100. In addition, in this embodiment, the insulator attachment part 201 is formed in the substantially C shape, and can be fitted now to the constriction part 103 of the insulator 100 from radial direction.

  The wire winding portions 202a and 202b extend from both ends of the insulator mounting portion 201, and each of them is previously bent into a spiral shape. In the present embodiment, a description will be given for the bind 200 in which the pair of wire winding portions 202a and 202b extend in opposite directions on both sides of the insulator mounting portion 201.

  In the bind 200 having the above-described configuration, the insulator attachment portion 201 is fitted to the constricted portion 103 of the insulator 100, and then the electric wire C partially aligned with the constricted portion 103 of the insulator 100 is used. By winding the electric wire winding portions 202a and 202b extending to both sides in order, the electric wire C is held by the electric wire winding portions 202a and 202b, and the electric wire C is fixed to the insulator 100.

  As described above, the bind wrapping tool according to the present embodiment is for winding the wire wrapping portions 202a and 202b of the bind 200 around the wire C, as shown in FIGS. 2 (a) and 2 (b). Thus, the winding tool main body 3 in which the interposition part 2 arrange | positioned between the electric wire C and electric wire winding part 202a, 202b in a parallel state was formed is provided.

  The said winding tool main body 3 is shape | molded by the insulating material (for example, synthetic resin), while the 1st contact part 4 made to contact the electric wire C is formed in the end of the interposition part 2, and an electric wire winding part A second abutment portion 5 that abuts against 202 a and 202 b is formed at the other end of the interposition portion 2. The winding tool body 3 is formed in a rod shape or a strip shape (in the present embodiment, a rod shape). In addition, as for the winding tool main body 3 in this embodiment, both ends are tapered toward the tip. Although this winding tool main body 3 may be solid or hollow, in this embodiment, it is formed from the viewpoint of ensuring strength.

  Further, in the bind wrapping tool 1, annular bodies 7, 7 are connected to both ends of the wrapping tool body 3. The annular bodies 7 and 7 according to the present embodiment are made of a string material in an annular shape, and the string material is inserted into a through-hole (not numbered) formed in the end portion of the winding tool body 3. It is formed by connecting both ends of the string material. The string material for forming the annular bodies 7 and 7 may be an electrically insulating hemp string or the like, but may be, for example, a conductive wire or the like whose outer periphery is insulated with a resin. When a conductive wire coated with insulation in this way is employed, electrical insulation can be ensured and the shape can be maintained in a predetermined shape by an internal wire (conductive wire).

  The winding tool body 3 rotates around the electric wire C while bringing the first contact portion 4 into contact with the electric wire C so that the second contact portion 5 pushes the electric wire winding portions 202a and 202b. It is configured. In the winding tool body 3 according to the present embodiment, a through hole 6 through which the wire winding portions 202a and 202b are inserted penetrates in a direction intersecting the longitudinal direction. The through-hole 6 is for inserting the wire winding portions 202a and 202b of the bind 200. In the present embodiment, the through-hole 6 is formed to penetrate in a direction orthogonal to the longitudinal direction of the winding tool body 3. . In the present embodiment, since the wire winding portions 202a and 202b are bent in a spiral shape, the hole diameter of the through hole 6 is set so that the wire winding portions 202a and 202b are inserted. , 202b is set larger than the outer diameter. That is, the hole diameter of the through hole 6 is set to a size that allows the inserted wire winding portions 202 a and 202 b to move in the hole center direction of the through hole 6.

  And the said through-hole 6 is formed in the approximate center part of the longitudinal direction of the winding tool main body 3, and the winding tool main body 3 is symmetrical with respect to the center of a longitudinal direction (one end side and the other end side are Are formed in substantially the same length).

  By providing the through-hole 6 in the winding tool body 3 in this way, the interposition part 2 is configured between the outer surface of the winding tool body 3 and the inner periphery that defines the through-hole 6, and the first contact The contact portion 4 is constituted by the outer surface of the winding tool body 3 (one end of the interposition portion 2), while the second contact portion 5 is constituted by the inner periphery of the through hole 6 (the other end of the interposition portion 2). ing. That is, in the winding tool body 3 according to the present embodiment, the hole center of the through hole 6 and the outer surface in the direction orthogonal to the longitudinal direction of the winding tool body 3 are set as the first contact portion 4, and the through hole 6 is a second contact portion 5 that is an inner peripheral surface of the first contact portion 4 and is separated from the first contact portion 4.

  And since the bind winding tool 1 which concerns on this embodiment forms the 2nd contact part 5 in the inner periphery by forming the through-hole 6 in the winding tool main body 3, winding Two intervening portions 2 are formed in a direction orthogonal to the longitudinal direction of the tool body 3. That is, the bind wrapping tool 1 according to the present embodiment has the intervening portions 2 formed on both sides of the through hole 6. Therefore, the bind wrapping tool 1 is formed with a pair of first contact portions 4, 4 at symmetrical positions with respect to an axis (through hole 6) extending in the longitudinal direction of the wrapping tool body 3.

  The bind wrapping tool 1 according to the present embodiment has the above configuration. Next, a method for winding the bind 200 around the electric wire C using the bind wrapping tool 1 will be described.

  First, the insulator attaching portion 201 is fitted into the constricted portion 103 of the insulator 100 attached to the support body while holding the bind 200 with the insulating yoke. Thereafter, the electric wire C is partially aligned with the constricted portion 103 while the electric wire C is held by the insulating jacket. That is, in a state where the lever attachment portion 201 formed in a C shape or a U shape is fitted to the constricted portion 103 of the insulator 100, a portion of the constricted portion 103 that is not surrounded by the lever attachment portion 201 remains. For this reason, a part of the long electric wire C is placed along the portion.

  In this state, the pair of wire winding portions 202a and 202b on both sides of the lever attachment portion 201 are extended in the same direction as the electric wire C partially along the constricted portion 103 of the lever 100. And the bind winding tool 1 (winding tool main body 3) is hold | maintained with an insulating yoke, and one electric wire winding part 202a is penetrated to the through-hole 6 of this winding tool main body 3. FIG. At this time, as shown in FIG. 3A, the bind wrapping tool 1 is disposed on the base end side (insulator mounting portion 201 side) of the wire winding portions 202a and 202b. In this embodiment, after attaching the insulator attachment portion 201 to the insulator 100, the wire winding portions 202a and 202b are inserted into the through holes 6. However, before attaching the insulator attachment portion 201 to the insulator 100, it penetrates in advance. The wire winding portions 202a and 202b may be inserted through the hole 6.

  Thus, by inserting the wire winding portions 202a and 202b through the through-hole 6, the interposition portion 2 is interposed between the wire winding portions 202a and 202b and the wire C, and the first contact portion 4 has a wire. C comes into contact, and the wire winding portions 202a and 202b come into contact with the second contact portion 5 (see FIG. 2B).

  Thereafter, the other wire winding portion 202b and the electric wire C are held together by the insulating YAT Y and the first contact portion 4 is brought into contact with the electric wire C while the winding tool body 3 is moved around the electric wire C. Rotate with At this time, it is possible to rotate the entire binding wrapping tool 1 by holding and pulling one end of the wrapping tool main body 3 with an insulating yarn, but in this embodiment, the wrapping tool main body is rotated. Since the annular bodies 7 and 7 are provided at both ends of 3, the hook-shaped tip tool F attached to the tip of the insulating operation rod S is hooked on the annular bodies 7 and 7 to pull the insulating operation rod S. The winding tool body 3 is rotated around the electric wire C.

  Then, as the winding tool body 3 rotates, one of the wire winding parts 202a comes into contact with the second contact part 5 and is pushed in the same direction as the rotation of the winding tool body 3, and as a result The wire winding portion 202a is wound around the wire C from the insulator mounting portion 201 (base end) side toward the tip. That is, since the end portion of the wound wrapping tool main body 3 serves as a power point and the first contact portion 4 serves as a rotation fulcrum of the wrapping tool main body 3, the second contact portion 5 serves as the wire winding portions 202a and 202b. As a result, the winding tool body 3 functions like a lever, and the wire winding portions 202a and 202b that are in a side-by-side state with the wire C are wound around the wire C. It will follow.

  And after rotating the winding tool main body 3 in the range in which tension | pulling with respect to one annular body 7 (one edge part of the winding tool main body 3) is accept | permitted, to FIG.3 (b) and FIG.3 (c). As shown, the annular bodies 7 and 7 (ends of the wrapping tool body 3) to be pulled by the insulating operation rod S are changed and pulled again (after pulling one end side, the other end side is pulled and the other end side is pulled. After pulling, the one end side is pulled), whereby the winding tool body 3 is rotated around the electric wire C. As described above, when the winding tool body 3 is rotated while alternately switching the end portions to be pulled, the wire winding portions 202a and 202b are sequentially from the base end side with respect to the wire C as described above. It will be wrapped around.

  As the wire winding portions 202a and 202b are sequentially wound around the wire C in this way, the winding tool body 3 arranged on the lever mounting portion 201 side is shown in FIGS. As shown to c), it moves to the front end side of electric wire winding part 202a, 202b one by one. As a result, in the state where the wire winding portions 202a and 202b are completely wound around the wire C, the insertion state of the wire winding portions 202a and 202b into the through hole 6 is released as shown in FIG. The Accordingly, the winding of the one wire winding portion 202a around the electric wire C is completed in a state where the wire winding portions 202a and 202b are detached from the through hole 6 of the winding tool body 3.

  In the present embodiment, since the wire winding portions 202a and 202b are provided on both sides of the insulator mounting portion 201, as described above, when the winding of the one wire winding portion 202a around the wire C is completed, the same procedure is performed. The other wire winding portion 202b is also wound around the wire C. And when each of a pair of wire winding part 202a, 202b is wound with respect to the electric wire C, the electric wire C with a part along the constriction part 103 of the insulator 100 will be the electric wire of the bind 200 on both sides of the insulator 100. It will be in the state hold | maintained at winding part 202a, 202b (refer FIG. 1).

  As described above, the bind wrapping tool 1 according to the present embodiment has the above-described configuration, so that the interposition part 2 is disposed between the electric wire C and the wire wrapping parts 202a and 202b in a parallel state. By simply rotating the winding tool body 3 around the electric wire C while bringing the one abutting part 4 into contact with the outer periphery of the electric wire C, the electric wire winding parts 202a and 202b are turned by the second contact part 5 into the winding tool body 3. Since it is pushed in the same direction as the rotation direction of the wire and wound around the electric wire C in a spiral manner, it is easy to rotate the winding tool body 3 around the electric wire C without requiring skill in the work. In operation, the wire winding portions 202a and 202b can be continuously wound around the wire C.

  In addition, the winding tool body 3 is formed in a rod shape or a band plate shape, and a through hole 6 through which the wire winding portions 202a and 202b are inserted penetrates in the longitudinal direction and the crossing direction. 2 is configured between an outer surface of the winding tool body 3 and an inner periphery that defines the through hole 6, and the first contact portion 4 is configured by an outer surface of the winding tool body 3, while the second The contact portion 5 is configured by the inner periphery of the through-hole 6 so that when the winding tool body 3 is rotated around the electric wire C, the wire winding portions 202a and 202b and the winding tool body 3 are integrated with each other. The wire winding portions 202a and 202b can be turned into the electric wire C only by rotating the winding tool body 3 without worrying about the posture of the wire winding portions 202a and 202b to be wound. Can be wound.

  Furthermore, the said through-hole 6 is formed in the approximate center part of the longitudinal direction of the winding tool main body 3, and even if any edge part of the winding tool main body 3 is made into a power point, the winding tool main body 3 is uniform. Can be smoothly rotated.

  In addition, the annular bodies 7 are connected to at least one end of the winding tool body 3 so that a hook (tip tool F) attached to the distal end of the insulating operation rod S is attached to the annular bodies 7, 7. The winding tool body 3 can be rotated around the electric wire C simply by hooking and simply pulling the insulating operation rod S.

  Next, a binding wrapping tool according to a second embodiment of the present invention will be described. The bind wrapping tool according to this embodiment is for winding a bind (wire wrapping portion) around an electric wire when the electric wire is fixed to the insulator using the same binding as in the first embodiment. Therefore, in the following description, components other than the binding wrapping tool will be omitted with reference to FIG. 1 and the same names and the same reference numerals as those in the first embodiment. In addition, regarding the binding wrapping tool, the same name and the same reference numeral are given for the sake of convenience with regard to the same or corresponding configuration as the configuration of the first embodiment.

  The bind winding tool 1 according to the present embodiment is for winding the wire winding portions 202a and 202b of the bind 200 around the wire C as described above, and is shown in FIGS. 4 (a) and 4 (b). As shown, a winding tool body 3 having an interposition part 2 disposed between the electric wire C and the wire winding parts 202a and 202b in a parallel state is provided.

  The said winding tool main body 3 is shape | molded by the insulating material (for example, synthetic resin), while the 1st contact part 4 made to contact the electric wire C is formed in the end of the interposition part 2, and an electric wire winding part A second abutment portion 5 that abuts against 202 a and 202 b is formed at the other end of the interposition portion 2. The winding tool body 3 is formed in a rod shape or a band plate shape (in this embodiment, a rod shape). The winding tool body 3 may be solid or hollow, but also in the present embodiment, it is solid from the viewpoint of securing strength.

  Further, also in the present embodiment, the bind wrapping tool 1 is provided with the annular bodies 7 and 7 at both ends of the wrapping tool main body 3, and the end portion of the wrapping tool main body 3 with the hook-shaped tip tool F. Can be pulled.

  The winding tool body 3 rotates around the electric wire C while bringing the first contact portion 4 into contact with the electric wire C so that the second contact portion 5 pushes the electric wire winding portions 202a and 202b. It is configured. In the winding tool body 3 according to the present embodiment, a through hole 6 through which the wire winding portions 202a and 202b are inserted penetrates in a direction intersecting the longitudinal direction. The through-hole 6 is for inserting the wire winding portions 202a and 202b of the bind 200. In this embodiment, the through-hole 6 penetrates in the direction orthogonal to the longitudinal direction of the winding tool body 3 and is wound. The tool body 3 is formed in a long hole shape extending in the longitudinal direction. In the present embodiment, since the wire winding portions 202a and 202b are spirally bent, the diameter of the through-hole 6 (the direction perpendicular to the longitudinal direction) is inserted through the wire winding portions 202a and 202b. Is set to be larger than the outer diameter of the wire winding portions 202a and 202b. That is, the hole diameter of the through hole 6 is set to a size that allows the inserted wire winding portions 202 a and 202 b to move in the hole center direction of the through hole 6.

  And the said through-hole 6 is formed so that the approximate center part of the longitudinal direction of the winding tool main body 3 may become the center of the longitudinal direction of this through-hole 6, and the longitudinal center of the winding tool main body 3 is formed. One end side and the other end side are set to have substantially the same length as a reference.

  By providing the through-hole 6 in the winding tool body 3 in this way, the interposition part 2 is configured between the outer surface of the winding tool body 3 and the inner periphery that defines the through-hole 6, and the first contact The contact part 4 is configured by the outer surface of the winding tool body 3 (one end of the interposition part 2), while the second contact part 5 is configured by the inner periphery of the through hole 6 (the other end of the interposition part 2). ing. That is, in the winding tool body 3 according to the present embodiment, the hole center of the through hole 6 and the outer surface in the direction orthogonal to the longitudinal direction of the winding tool body 3 are set as the first contact portion 4. A surface that is separated from the first contact portion 4 is set as the second contact portion 5.

  And since the bind winding tool 1 which concerns on this embodiment forms the 2nd contact part 5 in the inner periphery by forming the through-hole 6 in the winding tool main body 3, winding Two intervening portions 2 are formed in a direction orthogonal to the longitudinal direction of the tool body 3. That is, the bind wrapping tool 1 according to the present embodiment has the intervening portions 2 formed on both sides of the through hole 6. Therefore, a pair of the binding wrapping tool 1 is formed at symmetrical positions with respect to the axis (through hole 6) in which the first abutting portion 4 extends in the longitudinal direction of the wrapping tool main body 3.

  The bind wrapping tool 1 according to the present embodiment has the above configuration. Next, a method for winding the bind 200 around the electric wire C using the bind wrapping tool 1 will be described.

  First, the insulator attaching portion 201 is fitted into the constricted portion 103 of the insulator 100 attached to the support body while holding the bind 200 with the insulating yoke. Thereafter, the electric wire C is partially aligned with the constricted portion 103 while the electric wire C is held by the insulating jacket. That is, in a state where the lever attachment portion 201 formed in a C shape or a U shape is fitted to the constricted portion 103 of the insulator 100, a portion of the constricted portion 103 that is not surrounded by the lever attachment portion 201 remains. For this reason, a part of the long electric wire C is placed along the portion.

  In this state, the pair of wire winding portions 202a and 202b on both sides of the lever attachment portion 201 are extended in the same direction as the electric wire C partially along the constricted portion 103 of the lever 100. And the bind winding tool 1 (winding tool main body 3) is hold | maintained with an insulating yoke, and one electric wire winding part 202a is penetrated to the through-hole 6 of this winding tool main body 3. FIG. At this time, as shown in FIG. 5A, the bind wrapping tool 1 is disposed on the base end side (insulator mounting portion 201 side) of the wire winding portions 202a and 202b. In this embodiment as well, the wire winding portions 202a and 202b are inserted into the through-hole 6 after the insulator attachment portion 201 is attached to the insulator 100. However, before the insulator attachment portion 201 is attached to the insulator 100, it is penetrated in advance. The wire winding portions 202a and 202b may be inserted through the hole 6.

  Thus, by inserting the wire winding portions 202a and 202b through the through-hole 6, the interposition portion 2 is interposed between the wire winding portions 202a and 202b and the wire C, and the first contact portion 4 has a wire. C comes into contact, and the wire winding portions 202a and 202b come into contact with the second contact portion 5 (see FIG. 4B).

  Thereafter, the other wire winding portion 202b and the electric wire C are held together by the insulating YAT Y and the first contact portion 4 is brought into contact with the electric wire C while the winding tool body 3 is moved around the electric wire C. Rotate with At this time, the binding tool body 1 as a whole can be rotated by holding and pulling one of the ends of the winding tool body 3 with an insulating jacket, but also in this embodiment, the winding tool body. Since the annular bodies 7 and 7 are provided at both ends of the wire 3, a hook-shaped tip tool F attached to the tip of the insulating operation rod S is hooked on the annular body 7 and the insulation operation rod S is pulled to The accessory body 3 is rotated around the electric wire C.

  Then, as the winding tool body 3 rotates, one of the wire winding parts 202a comes into contact with the second contact part 5 and is pushed in the same direction as the rotation of the winding tool body 3, and as a result The wire winding portion 202a is wound around the wire C from the insulator mounting portion 201 (base end) side toward the tip. That is, since the end portion of the wound wrapping tool main body 3 serves as a power point and the first contact portion 4 serves as a rotation fulcrum of the wrapping tool main body 3, the second contact portion 5 serves as the wire winding portions 202a and 202b. As a result, the winding tool body 3 functions like a lever, and the wire winding portions 202a and 202b that are in a side-by-side state with the wire C are wound around the wire C. It will follow.

  In the bind wrapping tool 1 according to the present embodiment, since the through hole 6 is formed in a long hole shape, the electric wire winding portions 202a and 202b are located on one end side in the longitudinal direction of the through hole 6. In the state where the winding tool body 3 is slid in the longitudinal direction as described above, the annular bodies 7 on the other end side are pulled. Thereby, since the distance of a power point and a rotation fulcrum becomes longer than the distance of an action point and a rotation fulcrum, the winding tool main body 3 can be rotated with a small force.

  And after rotating the winding tool main body 3 in the range with which the tension | tensile_strength with respect to one annular body 7 (one edge part of the winding tool main body 3) is accept | permitted, to FIG.5 (b) and FIG.5 (c). As shown, the annular bodies 7 and 7 (ends of the wrapping tool body 3) to be pulled by the insulating operation rod S are changed and pulled again (after pulling one end side, the other end side is pulled and the other end side is pulled. After pulling, the one end side is pulled), whereby the winding tool body 3 is rotated around the electric wire C. At this time, the other end of the winding tool body 3 is slid in the longitudinal direction so that the wire winding portions 202a and 202b are located on either end side in the longitudinal direction of the through hole 6. The annular bodies 7 and 7 on the side are pulled. As described above, when the winding tool body 3 is rotated while alternately switching the end portions to be pulled, the wire winding portions 202a and 202b are sequentially from the base end side with respect to the wire C as described above. It will be wrapped around.

  As the electric wire winding portions 202a and 202b are sequentially wound around the electric wire C in this way, the winding tool main body 3 arranged on the lever attachment portion 201 side is shown in FIGS. As shown to c), it moves to the front end side of electric wire winding part 202a, 202b one by one. As a result, in the state where the wire winding portions 202a and 202b are completely wound around the wire C, the insertion state of the wire winding portions 202a and 202b into the through hole 6 is released as shown in FIG. The Accordingly, the winding of the one wire winding portion 202a around the electric wire C is completed in a state where the wire winding portions 202a and 202b are detached from the through hole 6 of the winding tool body 3.

Since it is pushed in the same direction as the rotation direction of the wire and wound around the electric wire C in a spiral manner, it is easy to rotate the winding tool body 3 around the electric wire C without requiring skill in the work. In operation, the wire winding portions 202a and 202b can be continuously wound around the wire C.

  The winding tool body 3 is formed in a bar shape or a strip shape, and a through hole 6 through which the wire winding portions 202a and 202b are inserted is formed so as to penetrate in a direction intersecting the longitudinal direction. The portion 2 is configured between the outer surface of the winding tool body 3 and the inner periphery that defines the through hole 6, and the first contact portion 4 is configured by the outer surface of the winding tool body 3, When the two abutting portions 5 are constituted by the inner periphery of the through-hole 6, when the winding tool body 3 is rotated around the electric wire C, the wire winding portions 202a and 202b and the winding tool body 3 are The wire winding portions 202a and 202b can be connected to the electric wire C simply by rotating the winding tool body 3 without worrying about the posture of the wire winding portions 202a and 202b to be wound.

  First, the insulator attaching portion 201 is fitted into the constricted portion 103 of the insulator 100 attached to the support body while holding the bind 200 with the insulating yoke. Thereafter, the electric wire C is partially aligned with the constricted portion 103 while the electric wire C is held by the insulating jacket. That is, in a state where the lever attachment portion 201 formed in a C shape or a U shape is fitted to the constricted portion 103 of the insulator 100, a portion of the constricted portion 103 that is not surrounded by the lever attachment portion 201 remains. For this reason, a part of the long electric wire C is placed along the portion.

  In this state, the pair of wire winding portions 202a and 202b on both sides of the lever attachment portion 201 are extended in the same direction as the electric wire C partially along the constricted portion 103 of the lever 100.

As a result, in the state where the wire winding portions 202a and 202b are completely wound around the wire C, the pressing by the second contact portion 5 against the wire winding portions 202a and 202b is released as shown in FIG. Is done. Accordingly, the winding of the one wire winding portion 202a around the electric wire C is completed in a state where the second contact portion 5 is detached from the wire winding portions 202a and 202b.

  In the present embodiment, since the wire winding portions 202a and 202b are provided on both sides of the insulator mounting portion 201, as described above, when the winding of the one wire winding portion 202a around the wire C is completed, the same procedure is performed.

By simply rotating the winding tool body 3 around the electric wire C while bringing the one abutting part 4 into contact with the outer periphery of the electric wire C, the electric wire winding parts 202a and 202b are turned by the second contact part 5 into the winding tool body 3. Since it is pushed in the same direction as the rotation direction of the wire and wound around the electric wire C in a spiral manner, it is easy to rotate the winding tool body 3 around the electric wire C without requiring skill in the work. In operation, the wire winding portions 202a and 202b can be continuously wound around the wire C.

  The winding tool body 3 is formed in a bar shape or a band plate shape, and a recess 10 into which the electric wire C is fitted is formed. The interposition part 2 defines the outer surface of the winding tool body 3 and the recess 10.

It is configured. The winding tool main body 3 according to the present embodiment is formed with a long hole-shaped slit portion 11 extending in the longitudinal direction and a communication portion 12 that allows the inside of the slit portion 11 to communicate with the outside. The slit portion 11 and the communication portion 12 penetrate in the same direction (a direction perpendicular to the longitudinal direction of the winding tool body 3). Accordingly, the electric wire C can be fitted into the slit portion 11 via the communication portion 12, and the electric wire C extends in the direction intersecting (orthogonal) with respect to the longitudinal direction of the winding tool body 3 in the slit portion 11. In this state, it can be moved in the longitudinal direction of the winding tool body 3.

  The bind wrapping tool 1 according to the present embodiment is formed such that the slit portion 11 matches the substantially central portion in the longitudinal direction of the wrapping tool body 3 with the center in the longitudinal direction of the slit portion 11. The one end side and the other end side are set to have substantially the same length with respect to the center in the longitudinal direction of the tool body 3. In the bind wrapping tool 1, the communication part 12 is formed at a substantially central part in the longitudinal direction of the wrapping tool body 3.

  By providing the slit part 11 in the winding tool body 3 in this way, the interposition part 2 is configured between the outer surface of the winding tool body 3 and the inner periphery that defines the slit part 11, and the first contact The contact portion 4 is configured by the inner peripheral surface of the slit portion 11, while the second contact portion 5 is configured by the outer surface of the winding tool body 3.

A surface that is separated from the second contact portion 5 is set as the first contact portion 4.

  The bind wrapping tool 1 according to the present embodiment has the above configuration. Next, a method for winding the bind 200 around the electric wire C using the bind wrapping tool 1 will be described.

  First, the insulator attaching portion 201 is fitted into the constricted portion 103 of the insulator 100 attached to the support body while holding the bind 200 with the insulating yoke. Thereafter, the electric wire C is partially aligned with the constricted portion 103 while the electric wire C is held by the insulating jacket. That is, in a state in which the insulator mounting portion 201 formed in a C shape or U shape is fitted to the constricted portion 103 of the insulator 100, a portion of the constricted portion 103 that is not surrounded by the insulator attaching portion 201 remains. For this reason, a part of the long electric wire C is placed along the portion.

  In this state, the pair of wire winding portions 202a and 202b on both sides of the lever attachment portion 201 are extended in the same direction as the electric wire C partially along the constricted portion 103 of the lever 100. And the binding part 1 (winding tool main body 3) is hold | maintained with an insulating Yatco, and the communication part 12 is arrange | positioned so that the interposition part 2 may be arrange | positioned between the electric wire C and the electric wire winding part 202a, 202b in a side-by-side state. The electric wire C is put into the slit portion 11 via At this time, as shown in FIG. 9A, the bind wrapping tool 1 is disposed on the base end side (insulator mounting portion 201 side) of the wire winding portions 202a and 202b.

  Thereafter, the other wire winding portion 202b and the electric wire C are held together by the insulating YAT Y and the first contact portion 4 is brought into contact with the electric wire C while the winding tool body 3 is moved around the electric wire C. Rotate with At this time, it is possible to rotate the entire binding wrapping tool 1 by holding and pulling one end of the wrapping tool main body 3 with an insulating yarn, but in this embodiment, the wrapping tool main body is rotated. Since the annular bodies 7 and 7 are provided at both ends of the wire 3, a hook-shaped tip tool F attached to the tip of the insulating operation rod S is hooked on the annular body 7 and the insulation operation rod S is pulled to The accessory body 3 can be rotated around the electric wire C.

  Then, as the winding tool body 3 rotates, one of the wire winding parts 202a comes into contact with the second contact part 5 and is pushed in the same direction as the rotation of the winding tool body 3, and as a result The wire winding portion 202a is wound around the wire C from the insulator mounting portion 201 (base end) side toward the tip. That is, since the end portion of the wound wrapping tool main body 3 serves as a power point and the first contact portion 4 serves as a rotation fulcrum of the wrapping tool main body 3, the second contact portion 5 serves as the wire winding portions 202a and 202b.

  Since the slit part 11 is formed in the shape of a long hole, the bind winding tool 1 according to the present embodiment is wound so that the electric wire C is located on one end side in the longitudinal direction of the slit part 11. While the tool body 3 is slid in the longitudinal direction, the annular bodies 7 on the other end side are pulled. Thereby, since the distance of a power point and a rotation fulcrum becomes longer than the distance of an action point and a rotation fulcrum, the winding tool main body 3 can be rotated with a small force.

  As the wire winding portions 202a and 202b are sequentially wound around the wire C in this way, the winding tool body 3 arranged on the lever mounting portion 201 side is shown in FIGS. As shown to c), it moves to the front end side of electric wire winding part 202a, 202b one by one. As a result, in a state where the wire winding portions 202a and 202b are completely wound around the wire C, the pressing by the second contact portion 5 against the wire winding portions 202a and 202b is released as shown in FIG. Is done. Accordingly, the winding of the one wire winding portion 202a around the electric wire C is completed in a state where the second contact portion 5 is detached from the wire winding portions 202a and 202b.

  In the present embodiment, since the wire winding portions 202a and 202b are provided on both sides of the insulator mounting portion 201, as described above, when the winding of the one wire winding portion 202a around the wire C is completed, the same procedure is performed. The other wire winding portion 202b is also wound around the wire C. And when each of a pair of wire winding part 202a, 202b is wound with respect to the electric wire C, the electric wire C with a part along the constriction part 103 of the insulator 100 will be the electric wire of the bind 200 on both sides of the insulator 100. It will be in the state hold | maintained at winding part 202a, 202b (refer FIG. 1).

  As described above, the bind wrapping tool 1 according to the present embodiment has the above-described configuration, so that the interposition part 2 is disposed between the electric wire C and the wire wrapping parts 202a and 202b in a parallel state. By simply rotating the winding tool body 3 around the electric wire C while bringing the one abutting part 4 into contact with the outer periphery of the electric wire C, the electric wire winding parts 202a and 202b are turned by the second contact part 5 into the winding tool body 3. Since it is pushed in the same direction as the rotation direction of the wire and wound around the electric wire C in a spiral manner, it is easy to rotate the winding tool body 3 around the electric wire C without requiring skill in the work. In operation, the wire winding portions 202a and 202b can be continuously wound around the wire C.

  In addition, the winding tool body 3 is formed in a bar shape or a band plate shape, and a slit portion 11 into which the electric wire C is fitted is formed. The interposition portion 2 includes the outer surface of the winding tool body 3 and the slit portion 11. The first contact portion 4 is formed by the inner periphery of the slit portion 11, while the second contact portion 5 is formed by the outer surface of the winding tool body 3. Thus, the winding tool body 3 can be stably rotated while being positioned with respect to the electric wire C. In particular, in the bind wrapping tool 1 according to the present embodiment, since the slit portion 11 is formed in a long hole shape, the distance between the force point and the rotation fulcrum is longer than the distance between the action point and the rotation fulcrum. The winding tool body 3 can be rotated with a small force.

  In addition, the annular bodies 7 are connected to at least one end of the winding tool body 3 so that a hook (tip tool F) attached to the distal end of the insulating operation rod S is attached to the annular bodies 7, 7. The winding tool body 3 can be rotated around the electric wire C simply by hooking and simply pulling the insulating operation rod S.

It is also possible to target the bind 200. Moreover, in each said embodiment, although the wire winding part 202a, 202b demonstrated to the bind 200 by which the bending process was carried out previously helically, it is not limited to this, For example, the wire winding part 202a, The binding 200 in which 202b is formed straight may be the target. That is, what is necessary is just the bind 200 provided with the electric wire winding part 202a, 202b wound around the electric wire C.

  In each of the above embodiments, the annular bodies 7 and 7 are provided at both ends of the wrapping tool body 3, and the hook-shaped tip tool F is hooked on the annular body 7. However, the present invention is not limited to this. For example, the end of the winding tool main body 3 may be sandwiched and pulled by an insulating jacket without providing the annular bodies 7 and 7. Moreover, when providing the annular bodies 7 and 7, it is not limited to what was provided in the both ends of the winding tool main body 3, You may make it provide in any one edge part of the winding tool main body 3. . Needless to say, it is better from the viewpoint of workability to provide the annular bodies 7 and 7 at the end of the wrapping tool body 3 so that the tip tool F can be hooked on the annular body 7.

  In each said embodiment, although the both ends of the winding tool main body 3 were tapered, it is not limited to this, It is set to the same diameter over a full length, or the center part of a longitudinal direction is rather than both ends. Of course, it may be set to a small diameter. Moreover, the winding tool main body 3 may be a hollow thing limited to a solid thing.

  In each of the above embodiments, the description has been made on the assumption that the winding tool body 3 is formed in a rod shape or a belt shape, but the present invention is not limited to this.

You may make it comprise the 2nd contact part 5. If it does in this way, electric wire winding part 202a, 202b is pushed by the 2nd contact part 5, and is wound around the electric wire C by making the ring-shaped winding tool main body 3 revolve around the electric wire C while rotating. become. In this case, it is preferable to form unevenness that is continuous in the circumferential direction with respect to the inner periphery and the outer periphery of the wrapping tool body 3 and to provide a slip stopper for the electric wire C and the electric wire winding portions 202a and 202b. By doing in this way, when revolving the winding tool main body 3 around the electric wire C, it becomes difficult to produce a slip between the electric wire C and the electric wire winding parts 202a and 202b, and the electric wire winding parts 202a and 202b are made. The wire C can be wound efficiently.

  In the second embodiment, the concave portion 10 into which the electric wire C is fitted is formed so as to be dug down straight. However, the present invention is not limited to this. For example, as shown in FIG. May be. That is, as the recess 10 into which the electric wire C is fitted, at least the first recess 10a dug down in the direction perpendicular to the longitudinal direction of the winding tool body 3 and at least the longitudinal direction of the winding tool body 3 from the back of the first recess 10a. What comprises the 2nd recessed part 10b extended to one edge part side is employ | adopted, and when rotating the winding tool main body 3, you may make it position the electric wire C in the 2nd recessed part 10b. If it does in this way, since it becomes difficult to drop the electric wire C from the recessed part 10, the winding tool main body 3 can be rotated smoothly. Needless to say, in this case, the inner periphery of the concave portion 10 (second concave portion 10b) is the first contact portion 4 that contacts the electric wire C.

  In said 2nd embodiment, while providing the recessed part 10 to which the electric wire C is engage | inserted in the winding tool main body 3, and making the 1st contact part 4 contacted with the electric wire C by the inner periphery of the recessed part 10, an electric wire winding part The second abutment portion 5 that abuts against the 202a and 202b is formed on the outer surface of the wrapping tool main body 3. For example, as shown in FIG. 12 and FIG. Then, the through-hole 6 through which the wire winding portions 202 a and 202 b are inserted may be formed in the winding tool body 3. In this case, the interposition part 2 arrange | positioned between the electric wire C and the electric wire winding part 202a, 202b is formed between the recessed part 10 and the through-hole 6, and the 1st contact part 4 is the inner periphery of the recessed part 10. In addition, the second contact portion 5 is configured by the inner periphery of the through hole 6. Thus, by providing the recessed part 10 and the through-hole 6, the effect | action and effect of the bind winding tool 1 of 1st embodiment can be added with respect to the bind winding tool 1 of 2nd embodiment. That is, when the wire winding portions 202a and 202b are wound around the wire C (when the winding tool body 3 is rotated around the wire C), the wire winding portions 202a and 202b and the winding tool body 3 are integrated with each other. The wire winding portions 202a and 202b can be turned into the electric wire C only by rotating the winding tool body 3 without worrying about the posture of the wire winding portions 202a and 202b to be wound. It becomes possible to wind.
