Description

  The present invention relates to an indirect tool. In particular, the present invention relates to an indirect tool for operating a wire coating stripping tool in indirect hot wire construction.

  Indirect hot-wire work associated with transformer work on high-voltage distribution lines will be carried out from stripping of the wire coating to insulation treatment in the live-wire state. Therefore, work is done without touching the current-carrying part of the wire directly using an insulating rod and a tip tool.

  Such indirect hot line construction often uses an aerial work vehicle. That is, the worker gets on the work floor attached to the tip of the movable part of the work device in the aerial work vehicle and approaches the workable position to work. An operator can perform work without directly touching the current-carrying portion of the electric wire, for example, by operating various tools attached to the tip of the shared insulating rod. In addition, since a sufficient separation distance can be secured, safety can be improved and work time can be shortened.

  When stripping the wire coating in indirect hot wire construction, a wire coating stripping tool is used. The wire covering stripping tool includes a first operating member provided with a screw hole for operating a blade for cutting the wire covering, and a support portion extending in a direction different from the first operating member by approximately 90 °. And a second operation member having an operation hole at the tip thereof. Conventionally, such a wire coating stripping tool has been operated using a bind hammer. The bind hammer has a hook shape extending from a support shaft and a pin extending substantially perpendicularly from the support shaft and on the same plane as the hook extension plane, and is used as a tip tool in various applications (for example, Patent Document 1). reference).

The method of operating the wire coating stripping tool with a bind punch is as follows. In the electric wire covering stripping tool attached to the electric wire, the hook shape is hooked into the screw hole of the first operation member and turned. As a result, the blade for cutting the wire coating is bitten into the coating. Next, the pin (or hook) of the bind hammer is inserted into the screw hole or the operation hole of the second operation member, and the operation of rotating the wire coating stripping tool itself around the center of the wire is performed. As a result, the coating of the electric wire is peeled off, and the process proceeds to a grounding process or the like.
Japanese Patent Laying-Open No. 2005-172752 (FIG. 3)

  FIG. 10 and FIG. 11 are diagrams showing a scene in which the wire covering stripping tool is operated with a bind punch. The wire covering stripping tool 100 extends in a direction that is approximately 90 ° different from the first operating member 103 provided with a screw hole 102 at the tip for operating the blade 101 for cutting the wire covering. And a second operation member 106 having an operation hole 105 at the tip of the support portion 104. The bind striker 200 includes a hook shape 203 extending from a support shaft 202 attached to the insulating rod 201, and a pin 204 extending substantially perpendicularly from the support shaft 202 and on the same plane as the hook extension plane.

  10 and 11, first, the wire covering stripping tool 100 has a support portion 104 of the second operation member 106 and a tip tool, for example, a wire gripper 300, which are not shown in FIG. It is hung on the electric wire 400 at a high place by an operation from the lower side of the worker on the work floor of the car. Subsequently, the operator hooks and turns the hook shape 203 of the bind hammer 200 into the screw hole 102 of the wire covering stripping tool 100. As a result, the blade 101 for cutting the wire coating is bitten into the coating of the wire 400. Next, the pin 204 (or hook shape 203) of the bind hammer is inserted into the operation hole 105 of the second operation member 106, and the wire covering stripping tool 100 itself is rotated once around the wire 400 as indicated by an arrow 10A. The operation is performed (see FIG. 10). At this time, the electric wire gripper 300 is holding the electric wire 400 in the vicinity of the electric wire covering stripping tool 100. While the operator performs the rotation operation of the wire covering stripping tool 100, in order to reduce the reaction force of the wire covering to be stripped, the rotating direction of the wire covering stripping tool 100 is opposite to the rotation direction (arrow 10B). The electric wire gripper 300 is held while applying force. Since the pin 204 of the bind hammer 200 extends substantially perpendicularly from the support shaft 202 and on the same plane as the extension plane of the hook shape 203, the rotation operation of the wire covering stripping tool 100 for inserting the pin 204 into the operation hole 105 is performed. At times, the hook-shaped portion 203 hits the support portion 104 and hinders the operation. Therefore, the operator tilts the bind hammer 200 so that the hook shape 203 does not hit the support portion 104 while the pin 204 of the bind hammer 200 is inserted into the operation hole 105 of the wire sheath stripping tool 100. We take a technique to survive this difficult situation. However, the worker is working on the work floor of an aerial work vehicle and is accompanied by a holding operation of the electric wire gripper 300 existing in the vicinity. For this reason, the operation range of the bind hammer 200 is limited to a considerably small size. Therefore, in the rotation operation around the electric wire 400 of the electric wire covering stripping tool 100 by the bind hammer 200, a knack is required to rotate 90 ° or more in one operation, and it is very difficult unless it is an expert.

  Furthermore, as shown in FIG. 11, as a final step regarding the rotation operation around the electric wire 400 of the electric wire covering stripping tool 100 subsequent to FIG. 10, the operator operates the bind hammer 200 to push up from below (arrow 11 </ b> A). ). This is due to work from below on the work floor of an aerial work vehicle. At this time, since the pin 204 of the bind hammer 200 is configured to extend from the support shaft 202 on the same plane as the extension plane of the hook shape 203, the second operating member 106 may not be able to completely cross the electric wire 400. There is. That is, regarding the rotation operation at the center of the electric wire 400 of the electric wire stripping tool 100 as indicated by the broken line arrow 11B, if the second operating member 106 does not exceed the vertical line 11C indicated by the broken line, the reaction force of the covered portion of the electric wire 400 and There is a high possibility that the wire covering stripping tool 100 will return in the direction opposite to the broken line arrow 11B due to its own weight balance of the wire covering stripping tool 100.

  Even if the hook shape 203 is inserted into the operation hole 105 instead of the pin 204 of the bind hammer 200 and the electric wire covering stripping tool 100 is rotated, the problem as shown in FIG. That is, when the operator operates the bind hitter 200 to push up from below (arrow 11A), the hook shape 203 easily comes out of the operation hole 105. Even if the hook shape 203 is operated so as not to come out of the operation hole 105, there is a possibility that the electric wire 400 cannot be completely passed over the second operation member 106.

  As described above, regarding the rotation operation around the electric wire 400 of the electric wire covering stripping tool 100, it is difficult to perform a continuous smooth rotation operation, and the second operating member 106 completely exceeds the electric wire 400 and the remaining weight is reduced. It is very difficult to perform the 1/4 rotation, and particularly an inexperienced worker has a problem of increasing the working time. The wire covering stripping work is, for example, work associated with grounding safety work for preventing a risk of an electric shock due to erroneous energization at the work target location, contact with other electric circuits, and induction. Such a time spent on the security work in the previous stage of the main work also leads to clogging up the main work in time, so it is desirable to avoid it as much as possible.

[First Embodiment]
FIG. 1 is a schematic view showing an indirect tool according to a first embodiment of the present invention. It is used as an indirect tool for operating a wire sheath stripping tool that strips the wire sheath as part of the indirect hot wire construction.

  The indirect tool 1 includes a support shaft 9, a first functional equipment 10 having a hook shape 15, and a second functional equipment 20 having a bar shape 25. The support shaft 9 is attached to the insulating support member 8, and is further attached to the insulating rod 5 such as a common insulating rod via the insulating support member 8. The insulating rod 5 has a configuration in which a part of the insulating support member 8 is sandwiched between the fixing protrusion 4 and the fixing ring screw 3, for example.

  The hook shape 15 in the first function equipment 10 extends obliquely from the support shaft 9 so as to be gradually separated from the extension line A1 of the support shaft 9, and extends through the transit point 11 away from the extension line A1. It approaches in the direction on A1, passes through the apex 12 near the extension line A1, and then extends to the terminal region 13 near the symmetrical position with the extension line A1 across the extension line A1. It is preferable that the apex 12 near the extension line A1 has a bending angle of approximately 90 °.

  The rod shape 25 in the second functional equipment 20 is substantially the same as the extension plane of the hook shape 15 with the portion that forms the hook shape 15 away from the extension line A1 of the support shaft 9, here the via location 11. It has a configuration that stands vertically. Assuming that the extension line A1 of the support shaft 9 is the vertical direction, the rod shape 25 can be arranged in an angle direction away from the vertical direction by a predetermined angle. The rod shape 25 is fixed by welding its base end portion to the via 11 of the hook shape 15. Although not shown in the drawings, the bar shape 25 may be configured to be fixed by a fixing tool such as a nut or a bolt from the opposite side to the extending direction of the bar shape 25 through a through hole provided in the via point 11. Regarding the cross-sectional area of the rod shape 25, the portion of the tip region 22 in the standing direction is large, and at least the cross-sectional area of the region portion 23 immediately below the tip region 22 is smaller than the portion of the tip region 22.

  The support shaft 9, the first function equipment 10 and the second function equipment 20 are all made of a material mainly composed of aluminum, and contribute to the weight reduction of the tip tool which can be handled more easily. Regarding the hook shape 15 in the first functional equipment 10, the length from the via point 11 to the apex 12 is about 35 mm to 50 mm, preferably 40 mm, and the length from the apex 12 to the terminal side region 13 is also about 35 mm to 50 mm, preferably 40 mm. The length of the rod shape 25 in the second functional equipment 20 is also 35 mm to 50 mm, preferably 40 mm.

  2, 3, and 4 (a) to 4 (d) are diagrams showing one scene in which the wire covering stripping tool is operated using the indirect tool according to the first embodiment. The wire covering stripping tool 100 extends in a direction that is approximately 90 ° different from the first operating member 103 provided with a screw hole 102 at the tip for operating the blade 101 for cutting the wire covering. And a second operation member 106 having an operation hole 105 at the tip of the support portion 104. In order to operate such an electric wire covering stripping tool 100, the indirect tool 1 shown in FIG. 1 is used.

  As shown in FIG. 2, first, the wire sheath stripping tool 100 is mounted on a work floor of an aerial work vehicle (not shown) to which the support portion 104 of the second operation member 106 and a tip tool such as a wire gripper 300 are fixed. It is hung on the electric wire 400 at a high place by an operation from below by a worker. Subsequently, the operator hooks and turns the hook shape 15 of the indirect tool 1 of the present invention in the screw hole 102 of the wire covering stripping tool 100. As a result, the blade 101 for cutting the wire coating is bitten into the coating of the wire 400.

  The rod shape 25 in the second functional equipment 20 can be provided at a location away from the extension line A1 of the support shaft 9 while suppressing the material cost by using the hook shape 15 in the first functional equipment 10. Therefore, the influence on the operation site (vertex 12) as the first functional equipment 10 is extremely small. That is, there is no problem in basic operations such as inserting, hooking, hooking and turning the hook shape 15. Further, the fact that the vertex 12 is bent at approximately 90 ° facilitates the basic operation and is easy to handle comprehensively. Further, the bar shape 25 is erected approximately 90 ° with respect to the extension plane of the hook shape 15. As a result, an increase in the rotation radius when the hook shape 15 is rotated about the support shaft 9 can be suppressed to a small value. Therefore, a smooth operation can be achieved without worrying about contact with the approaching wire gripper 300.

  Next, as shown in FIG. 3, the operator grips the electric wire 400 in the vicinity of the electric wire covering stripping tool 100 with the electric wire gripper 300. Then, the bar shape 25 of the indirect tool 1 is inserted into the operation hole 105 of the second operation member 106 of the wire sheath stripping tool 100, and the wire sheath stripping tool 100 itself is at least centered on the wire 400 as indicated by an arrow 31B. An operation of rotating once is performed (see FIGS. 4A to 4D). On the other hand, the operator holds the wire gripper 300 while applying a force in the direction opposite to the rotation direction (arrow 10B) of the wire sheath stripping tool 100 in order to reduce the reaction force of the wire sheath to be stripped. Hold.

  As shown in FIGS. 4A to 4D, the indirect tool 1 is operated to rotate the wire sheath stripping tool 100 itself around the wire 400 as indicated by an arrow 31B. Since the diameter of the tip region 22 is larger than the region portion 23 immediately below the rod shape 25 (see FIG. 3), it contributes to prevention of disconnection when being inserted into the operation hole 105 and operated. In the rotation operation of each figure, when the state of FIG. 4A is 0 °, FIG. 4B is a state where the rotation angle is over 90 °, and FIG. 4C is a state where the rotation angle is over 180 °. FIG. 4D shows a state in which the rotation angle has passed 270 °. Since the bar shape 25 extends in a direction different from the extension plane of the hook shape 15, there is almost no scene obstructed by the hook shape 15 when handling an object. That is, as shown in FIGS. 4A to 4D, the rotation surface and the extension plane of the hook shape 15 are the same surface, and the indirect tool 1 inserted into the operation hole 105 of the wire covering stripping tool 100 is used. The bar shape 25 protrudes from the rotating surface (projects deeply on the paper surface). For this reason, a series of rotation operations as shown in FIGS. 4A to 4D can be easily achieved without the hook shape 15 interfering with the second operation member 106.

  In FIG. 4D, as a final stage, the operator operates the indirect tool 1 so as to push up from below (arrow 41A). This is due to work from below on the work floor of an aerial work vehicle. The bar shape 25 of the indirect tool 1 is provided in the via 11 of the hook shape 15 away from the extension line A1 of the support shaft 9. That is, assuming that the extension line A1 of the support shaft 9 is the vertical direction, the bar shape 25 is arranged in an angle direction away from the vertical direction by a predetermined angle. Thereby, it becomes very easy to completely exceed the electric wire 400 for the second operating member 106 of the electric wire covering stripping tool 100. That is, as shown by the arrow 41A, the second operating member 106 of the wire sheath stripping tool 100 can easily exceed the vertical line 41C indicated by the broken line even when operated so as to push up from below. . Next, although not shown, the operator removes the bar shape 25 of the indirect tool 1 from the operation hole 105 of the wire covering stripping tool 100. Thereby, even if the reaction force of the covering portion of the electric wire 400 is applied, the electric wire covering stripping tool 100 can easily be subjected to the remaining 1/4 rotation (from 270 ° to 360 °) due to its own weight balance. ) Can be achieved.

  According to the indirect tool 1 according to the first embodiment of the present invention, the rod shape 25 in the second functional equipment 20 is separated from the extension line A1 of the support shaft 9 by using the hook shape 15 in the first functional equipment 10. It is possible to provide a configuration which can be provided at a distant place and is erected with respect to the extension plane of the hook shape 15, more preferably substantially perpendicularly. As a result, the first function equipment 10 and the second function equipment 20 are compactly gathered first from the support shaft 9, and the functions of the first and second function equipments 10 and 20 are not impaired. Indirect tools can be realized.

  That is, the hook shape 15 is used for operations such as inserting, hooking, and turning a screw of the first operation member 103 that causes the wire coating cutting blade 101 to act on the wire coating stripping tool 100. However, the operation can be smoothly achieved without being obstructed by the rod shape 25. Further, the rod shape 25 is inserted into the operation hole 105 of the second operation member 106 extending in a direction different from the first operation member of the electric wire covering stripping tool 100 by about 90 °, and the electric wire covering stripping tool 100 is inserted. Although used for the operation of rotating around the electric wire 400, the operation can be smoothly achieved without being hindered by the hook shape 15. Moreover, the rod shape 25 can be operated so that the electric wire covering stripping tool 100 can be easily passed over the electric wire 400 from below. Thereby, the indirect tool which can handle easily the predetermined | prescribed electric wire coating stripping tool 100 in indirect hot wire construction can be provided.

[Second Embodiment]
FIG. 5 is a schematic view showing an indirect tool according to the second embodiment of the present invention. FIG. 5 shows a modification of the indirect tool shown in the first embodiment.

  The indirect tool 2 includes a support shaft 7, a first functional equipment 30 having a hook shape 35, and a second functional equipment 40 having a bar shape 45. The support shaft 7 is attached to the insulating support member 6, and is further attached to the insulating rod 5 such as a common insulating rod via the insulating support member 6. The insulating rod 5 has a configuration in which a part of the insulating support member 6 is sandwiched between the fixing protrusion 4 and the fixing ring screw 3, for example.

  The hook shape 35 in the first functional equipment 30 extends obliquely from the support shaft 7 so as to be gradually separated from the extension line A2 of the support shaft 7, and extends through a transit point 31 away from the extension line A2. It approaches the direction on A2, passes through the apex 32 in the vicinity on the extension line A2, and then extends to the terminal side region 33 in the vicinity of the symmetric position with the extension line A2 separated from the transit point 31. The vertex 32 in the vicinity on the extension line A2 preferably has a bending angle of approximately 90 °.

  The bar shape 45 in the second functional equipment 40 is located away from the extension line A2 of the support shaft 7 in the portion forming the hook shape 35, here, with respect to the extension plane of the hook shape 35 with the terminal region 33 as the base end. It has a configuration that stands substantially vertically. Assuming that the extension line A2 of the support shaft 7 is the vertical direction, the bar shape 45 can be arranged in an angle direction away from the vertical direction by a predetermined angle. The rod shape 45 is formed by extending the members constituting the hook shape 35. Regarding the cross-sectional area of the rod shape 45, the portion of the tip region 42 in the standing direction is large, and at least the cross-sectional area of the region portion 43 immediately below the tip region 42 is smaller than the portion of the tip region 42. In this embodiment, a detachment preventing member 46 having a cylindrical shape larger in diameter than the rod shape 45 is formed in the tip region 42 so that the tip region 42 is not detached from the screw hole 102 or the operation hole 105. ing. That is, the portion of the distal end region 42 is substantially larger than the cross-sectional area of the region portion 43 by the detachment preventing member 46. For example, the detachment preventing member 46 may be colored in a different color from other regions (particularly, a color that is easily visible at night, such as red or yellow).

  The support shaft 7, the first function equipment 30 and the second function equipment 40 are all made of a material mainly composed of aluminum, and contribute to the weight reduction of the tip tool which can be made easier to handle. Since the bar shape 45 is formed by extending the members constituting the hook shape 35, the manufacturing process is simplified as compared with the configuration of the first embodiment. Regarding the hook shape 35 in the first functional equipment 30, the length from the transit point 31 to the apex 32 is generally 35 mm to 50 mm, preferably 40 mm, and the length from the apex 32 to the terminal side region 33 is also generally 35 mm to 50 mm, preferably 40 mm. The length of the rod shape 45 in the second functional equipment 40 is also 35 mm to 50 mm, preferably 40 mm.

  6, 7 and 8 (a) to 8 (d) are diagrams showing a scene in which the electric wire stripping tool is operated using the indirect tool according to the second embodiment. Since the wire sheath stripping tool 100 has the same configuration as the wire sheath stripping tool 100 described with reference to FIG. In order to operate such a wire covering stripping tool 100, the indirect tool 2 shown in FIG. 5 is used.

  As shown in FIG. 6, first, the wire sheath stripping tool 100 is mounted on a work floor of an aerial work vehicle (not shown) to which the support portion 104 of the second operation member 106 and a tip tool, for example, the wire gripper 300 are fixed. It is hung on the electric wire 400 at a high place by an operation from below by a worker. Subsequently, the operator hooks and turns the hook shape 35 of the indirect tool 2 of the present invention on the screwing hole 102 of the wire covering stripping tool 100. The colored detachment prevention member 46 is easy to visually recognize, and has an advantage that it can be easily inserted into the screw hole 102. The operator inserts the rod shape 45 into the screw hole 102 and then turns the hook shape 35 to function while moving the hook shape 35 just below the apex 32 of the hook shape 35 while twisting about 1/4 turn. As a result, the blade 101 for cutting the wire coating is bitten into the coating of the wire 400.

  The bar shape 45 in the second functional equipment 40 can be provided at a location away from the extension line A2 of the support shaft 7 while suppressing the material cost by using the hook shape 35 in the first functional equipment 30. Therefore, the influence on the operation site (vertex 32) as the first functional equipment 30 is extremely small. In other words, the hook shape 35 is not hindered in basic operations such as insertion, hooking, hooking and turning. Further, the fact that the apex 32 is bent at approximately 90 ° facilitates the basic operation and is easy to handle comprehensively. Further, the bar shape 45 is erected approximately 90 ° with respect to the extension plane of the hook shape 35. As a result, an increase in the rotation radius when the hook shape 35 is rotated about the support shaft 7 is suppressed to a small value. Therefore, a smooth operation can be achieved without worrying about contact with the approaching wire gripper 300.

  Next, as shown in FIG. 7, the operator grips the electric wire 400 in the vicinity of the electric wire covering stripping tool 100 with the electric wire gripper 300. Then, the bar shape 45 of the indirect tool 2 is inserted into the operation hole 105 of the second operation member 106 of the wire sheath stripping tool 100, and the wire sheath stripping tool 100 itself is at least centered on the wire 400 as shown by an arrow 71B. An operation of rotating once is performed (see FIGS. 8A to 8D). On the other hand, the operator holds the wire gripper 300 while applying a force in the direction opposite to the rotation direction (arrow 10B) of the wire sheath stripping tool 100 in order to reduce the reaction force of the wire sheath to be stripped. Hold.

  As shown in FIGS. 8A to 8D, the indirect tool 2 is operated to rotate the wire covering stripping tool 100 itself around the wire 400 as indicated by an arrow 71B. Since the diameter of the tip region 42 is larger than the region portion 43 immediately below the rod shape 45 (see FIG. 7), it contributes to prevention of disconnection when being inserted into the operation hole 105 and operated. In the rotation operation of each figure, when the state of FIG. 8A is 0 °, FIG. 8B is a state where the rotation angle is over 90 °, and FIG. 8C is a state where the rotation angle is over 180 °. FIG. 8D shows a state where the rotation angle has passed 270 °. Since the bar shape 45 extends in a direction different from the extension plane of the hook shape 35, there is almost no scene that is hindered by the hook shape 35 when the object is handled. That is, as shown in FIGS. 8A to 8D, the rotating surface and the extension plane of the hook shape 35 are the same surface, and the indirect tool 2 inserted into the operation hole 105 of the wire covering stripping tool 100. The bar shape 45 protrudes from the rotating surface (projects deeply on the paper surface). Therefore, a series of rotation operations as shown in FIGS. 8A to 8D can be easily achieved without the hook shape 35 hindering the second operation member 106.

  In FIG. 8D, as a final stage, the operator operates the indirect tool 2 so as to push up from below (arrow 81A). This is due to work from below on the work floor of an aerial work vehicle. The bar shape 45 of the indirect tool 2 is provided in the terminal side region 33 of the hook shape 35 away from the extension line A2 of the support shaft 7. That is, assuming that the extension line A2 of the support shaft 7 is the vertical direction, the bar shape 45 is arranged in an angle direction away from the vertical direction by a predetermined angle. Thereby, it becomes very easy to completely exceed the electric wire 400 for the second operating member 106 of the electric wire covering stripping tool 100. That is, as shown by the arrow 81A, the second operating member 106 of the wire sheath stripping tool 100 can easily exceed the vertical line 81C indicated by the broken line even when operated so as to push up from below. . Next, although not shown, the operator pulls out the bar shape 45 of the indirect tool 2 from the operation hole 105 of the wire covering stripping tool 100. Thereby, even if the reaction force of the covering portion of the electric wire 400 is applied, the electric wire covering stripping tool 100 can easily be subjected to the remaining 1/4 rotation (from 270 ° to 360 °) due to its own weight balance. ) Can be achieved.

  According to the indirect tool 2 according to the second embodiment of the present invention, the bar shape 45 in the second function equipment 40 is separated from the extension line A2 of the support shaft 7 by using the hook shape 35 in the first function equipment 30. It is possible to provide a configuration which can be provided at a distant place and is erected with respect to the extension plane of the hook shape 35, more preferably substantially perpendicularly. As a result, the first function equipment 30 and the second function equipment 40 are compactly gathered first from the support shaft 7, and the functions of the first and second function equipments 30 and 40 are not impaired. Indirect tools can be realized.

  That is, the hook shape 35 is used for operations such as insertion, hooking, and turning of the screw of the first operation member 103 that causes the wire coating cutting blade 101 to act on the wire coating stripping tool 100. However, the operation can be smoothly achieved without being obstructed by the bar shape 45. Further, the bar shape 45 is inserted into the operation hole 105 of the second operation member 106 extending in a direction different from the first operation member in the wire coating stripping tool 100 by approximately 90 °, and the wire coating stripping tool 100 is inserted. Although used for the operation of rotating around the center of the electric wire 400, the operation can be smoothly achieved without being hindered by the hook shape 35. Moreover, the bar shape 45 can be operated so that the electric wire coating stripping tool 100 can be easily passed over the electric wire 400 from below. Thereby, the indirect tool which can handle easily the predetermined | prescribed electric wire coating stripping tool 100 in indirect hot wire construction can be provided.

  FIG. 9 shows a state diagram of a three-wire ground short-circuit process. The electric wires 401, 402, and 403 in the high place are provided with a predetermined portion of the electric wire covering using the predetermined electric wire covering stripping tool 100 and the indirect tool 1 or 2 shown in the first or second embodiment for the operation. Stripped off. Thereafter, the connection clamps 94, 95, 96 are lifted upward using an insulating rod (not shown) with the grounded conductors 91, 92, 93 by the ground side terminal 90, and each wire coating is peeled off. Connected to the site. This prevents the risk of electric shock due to mis-energization at the work destination, cross-contact from other electric circuits, and induction.

  It is very useful to use the indirect tool 1 or 2 as shown in the first or second embodiment according to the present invention in the safety work in the previous stage for safely performing the target work. is there. It is very useful to use the indirect tool 1 or 2 as shown in the first or second embodiment according to the present invention for the operation of the wire covering stripping tool 100. This is because wasting time in the previous stage of the target work will also clog up the main work time later. It takes a lot of time to strip the wire coating, which is bad for the eye. By using the indirect tool according to the present invention, it is possible to easily and efficiently handle a predetermined wire coating stripping tool in indirect hot wire construction. The work efficiency can be expected to increase not only by skilled workers but also by inexperienced workers.
