Description

[0001]
BACKGROUND OF THE INVENTION
The present invention uses a bind wire attaching / detaching tool and a bind wire attaching / detaching tool used for attaching or removing a bind wire to or from a high voltage wire to fix the high voltage wire to a high voltage pin insulator in a state of being wound around the high voltage wire. The present invention relates to a method for attaching and detaching a bind wire that can be suitably attached or detached.
[0002]
[Prior art]
In general, when the work to fix the high-voltage line to the high-voltage pin insulator by the bind line or the work to replace the deteriorated bind line with a new one, it is performed in a live line state where power is supplied to the existing high-voltage line. Yes. This is because if construction is performed with the power supply side circuit at the location where the high-voltage line is fixed to the high-voltage pin insulator shut off, a wide range of power consumers will be affected during the construction. Conventionally, in the above-mentioned construction, wearing a protective device for insulation such as a high-pressure rubber glove or an insulation garment and performing a direct live-line work in which the work is performed by directly touching the high-voltage live part in a live line state, Direct hot-line work involves some dangers compared to work in a power failure state, and is easily affected by the weather.
[0003]
Therefore, in recent years, a so-called “hot stick method” has been adopted in which a bind wire is wound or removed from a high-voltage wire in a live state by an indirect operation by remote operation using an insulating operation tool. When attaching / detaching the bind wire by this “hot stick method”, a bind wire attaching / detaching tool in which an attaching / detaching operation member having a ring-shaped hook portion and a terminal raising portion is fixed to the tip of an insulating operation rod is employed. .
[0004]
For example, when removing the binding wire using the above-mentioned binding wire attaching / detaching tool, the insulating operation rod is used so that the terminal raising portion is turned between the end portion of the binding wire and the high-voltage wire after the terminal raising portion is inserted. , Pull the end of the bind wire in the direction opposite to the winding direction of the high-voltage wire, insert the end of the bound bind wire into the ring-shaped hook, and then the ring-shaped hook. This is performed in a procedure that repeats the operation of operating the insulating operation rod so as to rotate the part in the direction opposite to the winding direction of the bind line around the high-voltage line. On the other hand, when the bind wire is wound around and attached to the high voltage wire, the procedure is the reverse of the above-described removal.
[0005]
[Problems to be solved by the invention]
However, since the above-mentioned bind wire attaching / detaching tool repeats the operation of turning the ring-shaped hook portion having the bind wire inserted therein along the periphery of the high-voltage line, the ring-shaped hook portion is connected to the high-voltage line. The ring-shaped hook part is pulled out from the bind line every rotation about one turn, and after the attachment / detachment operation member is moved to the opposite side of the high-voltage line from the pull-out position, the bind line is inserted again into the ring-shaped hook part, The operation of rotating the detachable operation member along the periphery of the high-voltage line must be repeated. That is, in the bind wire attaching / detaching tool, the operation of engaging and disengaging the attaching / detaching operation member with respect to the bind line must be repeated. For this reason, there is a drawback that it takes a very long time to attach or remove the bind line using the bind line attaching / detaching tool.
[0006]
Moreover, in the above-described bind wire attaching / detaching tool, the attach / detach operation member is rotated around the high voltage line in an unstable state in which the bind wire is simply inserted into the ring-shaped hook portion and no part is supported. This requires not only a large operating force, but also the ring-shaped hook part is easy to slide along the bind line during operation, so the terminal cap that protects the end of the bind line is removed. May occur.
[0007]
Therefore, the present invention has been made in view of the above-described conventional problems, and it is possible to attach or remove a bind line in a short time by repeating an easy operation that does not require a large operation force almost continuously. It is an object of the present invention to provide a wire attaching / detaching method capable of suitably attaching or removing a bind wire using the wire attaching / detaching tool and the bind wire attaching / detaching tool.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a binding wire attaching / detaching tool according to an embodiment of the present invention, and FIGS. 2A to 2C are a front view and a right side view showing an attaching / detaching operation member in the binding wire attaching / detaching tool. It is the top view partially broken. As shown in FIG. 1, the binding wire attaching / detaching tool has a configuration in which an attaching / detaching operation member 2 is fixed to a tip portion of an insulating operation rod 1.
[0015]
The detachable operation member 2 is arranged in a direction orthogonal to the insulating operation rod 1, a base portion 3 constituting the main body portion thereof, a mounting portion 4 extending from the base portion 3 and fixed to the tip of the insulating operation rod 1. A rotating portion 7 rotatably attached to the base portion 3 through the rotating support shaft 8, and a support hook portion 9 attached to rotate integrally with the rotating portion 7 in an arrangement parallel to the insulating operation rod 1. The insulator shaft body portion 10 fixed to the outer surface of the front end of the support hook portion 9 and the rotating portion 7 of the base portion 3 are provided with a terminal raising portion 11 provided on the opposite side.
[0016]
The support hook portion 9 is formed with a rotation support portion 9a that is curved in a substantially semicircular shape with a radius of curvature corresponding to the outer diameter of a high-voltage line to be described later. At one end portion of the insulator shaft body portion 10, a sharpening portion 10a having a sharp shape is formed. Further, the rotating portion 7 is rotated about a rotation support shaft 8 orthogonal to the insulating support rod 1 and a light load is applied so that free rotation is restricted by a known ball plunger (not shown). Further, a pivoting function is provided in which the rotation support portion 9a of the support hook portion 9 is lightly temporarily fixed to the illustrated posture of FIG.
[0017]
Next, a procedure for removing the binding line using the binding line attaching / detaching tool will be described. As shown in FIG. 3, the high-voltage wire 12 has a bind wire 13 wound around itself, and a latching curved portion 13 a formed at the center of the bind wire 13 is latched on the high-pressure pin insulator 14. The high-pressure pin insulator 14 is fixed. The bind wire 13 is formed by coating a hard metal wire with an insulating member made of rubber, for example, and both ends thereof are protected by attaching terminal caps 17. The bind line 13 is replaced with a new one when the specified service life has elapsed. When removing the existing bind wire 13, first, as shown in FIG. 3, the pegging portion 10 of the insulator shaft body portion 10 is inserted into the gap between the one end portion of the bind wire 13 and the high-voltage wire 12.
[0018]
At the time of the above operation, as shown in FIG. 4A, the position of the lever 10 a of the lever shaft 10 in the detachable operation member 2 is set upward and the position of the lever 10 a is set to the high-voltage line 12. On the other hand, from the side of the high-voltage pin insulator 14, it is inserted from below into the gap between the high-voltage line 12 and one end of the bind line 13. The posture of the lever shaft body portion 10 of the attachment / detachment operation member 2 with the pry-in portion 10a facing upward can be easily set because it is biased by a ball plunger so as to be temporarily fixed in this state. In addition, when the gap between the one end portion of the bind wire 13 and the high-voltage wire 12 is small, it is difficult to smoothly insert the above-described prying portion 10 a between the high-voltage wire 12 and one end portion of the bind wire 13. The terminal raising portion 11 is used to remove the end of the bind wire 13 from the high voltage wire 12 so that the knurling portion 10a can be smoothly inserted between the high voltage wire 12 and one end of the bind wire 13. It is preferable to form in advance a gap that can be inserted.
[0019]
When the insulator shaft body portion 10 has been inserted into the gap between the high voltage wire 12 and one end portion of the bind wire 13 from the pegging portion 10a, as shown by the arrow A in FIG. The insulating operation rod 1 is operated so that 2 passes through the lower side of the high-voltage line 12 and rotates toward the side opposite to the high-pressure pin insulator 14 (front side in the figure). At this time, the insulator shaft body portion 10 rotatably provided around the rotation support shaft 8 positioned in the orthogonal direction with respect to the insulating support rod 1 supports the high-voltage line 12 firmly stretched, While being rotated smoothly around the high-voltage line 12 in principle, one end of the bind wire 12 is forced in the direction opposite to the winding direction of the high-voltage line 12 as shown by the solid line in FIG. The screw is removed from the high-voltage wire 12 toward the screw. When the attachment / detachment operation member 2 is rotated from the solid line position in FIG. 4B to the two-dot chain line position, the bind line 13 is wound about one turn around the high-voltage line 12 as shown by the two-dot chain line in the figure. It is removed only by the minute.
[0020]
In the illustrated example, the above-described attaching / detaching operation member 2 is moved below the high-voltage line 12 to the side opposite to the high-voltage pin insulator 14 in the rotational direction of the insulator shaft body portion 10 at that time. This is because the direction in which the bind wire 13 is wound around the high-voltage wire 12 is opposite. In short, the insulator shaft body portion 10 may be rotated in a direction opposite to the winding direction of the bind wire 13 around the high voltage wire 12.
[0021]
When the bind wire 13 is removed by the amount of winding about one turn around the high-voltage wire 12, the attaching / detaching operation member 2 is arranged below the base portion 3 as shown by a two-dot chain line in FIG. Since the lever shaft body portion 10 is positioned so as to move above the high-voltage line 12 on the side opposite to the high-pressure pin insulator 14 (the front side in the figure), the posture of the attaching / detaching operation member 2 is next changed. Then, the posture is changed so that the work of removing the binding wire 13 can be continued.
[0022]
That is, the attachment / detachment operation unit 2 is in the posture of the two-dot chain line in FIG. 4B when the binding wire 13 has been removed from the high-voltage wire 12 by approximately one turn, and from one end of the bind wire 13. It is temporarily retracted to a position slightly away (position on the left side in the figure). Subsequently, as shown by a two-dot chain line in FIG. 5A, the attaching / detaching operation member 2 passes under the high-voltage line 12 to the high-pressure pin insulator 14 side (the other side in the figure) by the operation with the insulating operation rod 1. After returning, the high voltage line 12 is fitted into the rotation support portion 9a of the support hook portion 9. Therefore, when the attachment / detachment operation member 2 is rearranged from the position indicated by the two-dot chain line in FIG. 4B to the position indicated by the two-dot chain line in FIG. 5A, an operation of changing the posture of the attachment / detachment operation member 2 is required. There is no need to operate the insulation operating rod 1 so that the attaching / detaching operation member 2 is displaced through the lower side of the high voltage line 12 toward the high voltage pin insulator 14 with respect to the high voltage line.
[0023]
The attachment / detachment operation member 2 disposed at the position indicated by the two-dot chain line in FIG. 5A is configured to slide the rotation support portion 9a of the support hook portion 9 along the high-voltage line 12 by operating the insulating support rod 1. As shown by the solid line in FIG. 5A, the rotation support portion 9a is brought into contact with the high-voltage line 12 between the end of the bind wire 13 wound around the high-voltage line 12 and the high-voltage line 12. Insert until In this state, as shown in FIG. 5 (b), with the high voltage line 12 fitted in the rotation support portion 9a as a fulcrum, the insulating operation rod is rotated so that the support hook portion 9 is rotated via the rotation portion 7. By operating 1, the attaching / detaching operation member 2 is rotated with a rotation trajectory passing below the high-voltage line 12 toward the opposite side of the high-voltage pin insulator 14 with respect to the high-voltage line 12. At this time, the insulator shaft body portion 10 that rotates integrally with the support hook portion 9 forcibly turns the bind wire 13 in the direction opposite to the winding direction around the high-voltage wire 12.
[0024]
The operation of the above-described insulating operation rod 1 is performed by using the high-voltage line 12 fitted in the rotation support part 9a of the support hook part 9 as a fulcrum, and the insulator shaft body part 10 from the high-voltage line 12 to the bind line 13 by the principle of leverage. Since it is made to act so as to be removed, it can be carried out stably without fear of slipping and easily without requiring a large operating force.
[0025]
The illustrated position in FIG. 5B, which is the turning process of the detachable operation member 2, is the same as the illustrated position in the two-dot chain line in FIG. 6A, and the two-dot chain line in FIG. 6A is illustrated. When the detachable operation member 2 is rotated from the position in the direction of the arrow to the illustrated position of the solid line, the bind wire 13 is further removed from the high-voltage wire 12 by one turn. Thereafter, the operations described in FIGS. 5A and 5B and FIG. 6A are repeated a required number of times.
[0026]
That is, the attachment / detachment operation unit 2 is slightly separated from one end portion of the bind wire 13 while sliding the rotation support portion 9a along the high-voltage line 12 while maintaining the posture illustrated by the solid line in FIG. It is evacuated until. Subsequently, the detachable operation member 2 is insulated from the high voltage line 12 so as to rotate to the opposite side with respect to the high voltage line 12 with the high voltage line 12 fitted in the rotation support part 9a of the support hook part 9 as a fulcrum. The operation rod 1 is operated. At this time, the rotation support portion 9a slides around the high-voltage line 12 and rotates about the high-voltage line 12, and the base 3 of the detachable operation member 2 returns again to the position on the high-pressure pin insulator 14 side with respect to the high-voltage line 12. Then, the posture is indicated by a two-dot chain line in FIG.
[0027]
The attachment / detachment operation member 2 at the illustrated position of the two-dot chain line is moved in the direction of the arrow while sliding the rotation support portion 9a of the support hook portion 9 along the high-voltage line 12, as indicated by the arrow, and the lever shaft. The body part 10 is inserted between the bind line 13 and the high voltage line 12 which have been removed, and the rotation support part 9a is connected to the high voltage line 12 in the bind line 13 as shown by a solid line in FIG. Insert until it is in contact between the winding end and the high-voltage wire 12. In this state, the insulating operation rod 1 is operated so as to rotate the support hook portion 9 via the rotation portion 7 with the high-voltage line 12 fitted in the rotation support portion 9a as a fulcrum, as described above. Thus, the attaching / detaching operation member 2 is rotated with a rotation locus passing below the high-voltage line 12 toward the opposite side of the high-voltage pin insulator 14 with respect to the high-voltage line 12. At this time, the insulator shaft body portion 10 that rotates integrally with the support hook portion 9 forcibly turns the bind wire 13 in the direction opposite to the winding direction around the high-voltage wire 12, and the bind wire 13 with respect to the high-voltage wire 12. Only one turn is removed.
[0028]
When the above operation is repeated and the portion of the bind wire 13 up to the front of the latching bending portion 13a is removed from the high-voltage wire 12, the other half of the binding wire 13 on the other end side of the latching bending portion 13a is removed. Remove by performing the same operation as described above. Finally, when the latching curved portion 13a of the bind wire 13 is removed from the high-pressure pin insulator 14, the work for removing the bind wire 13 is completed.
[0029]
In the removing operation of the bind wire 13 using the above-described bind wire attaching / detaching tool, first, the koji insertion portion 10a of the insulator shaft body portion 10 is inserted between the end portion of the bind wire 13 and the high-voltage wire 12, If the end of the bind wire 13 is detached from the high-voltage wire 12 by rotating the insulator shaft body portion 10 with the high-voltage wire 12 as a fulcrum, the high-voltage wire 12 will be inserted into the rotation support portion 9a of the support hook portion 9 thereafter. While maintaining the fitted state at all times, the operation of sliding the attachment / detachment operation member 2 along the high-voltage line 12 and the operation of rotating the high-voltage line 12 around the fulcrum can be continuously performed, and the insulating operation rod 1 The lever shaft body 10 is rotated by the lever principle with the high-voltage line 12 as a fulcrum through the rotating portion 7 that rotates about the axis in the orthogonal direction, so that a large operating force is not required. Easy and smooth operation Since it becomes possible to carry out in a short period of time to disassemble the binding wire 13. In addition, since the removal work can be performed stably without sliding, there is no possibility that the terminal cap 17 of the bind wire 13 is detached during the removal work.
[0030]
Note that after the latching curved portion 13a of the new bind wire 13 is hooked on the high voltage pin insulator 14, the bind wire 13 is wound around the high voltage wire 12, and the high voltage wire 12 is connected to the high voltage pin insulator 14 via the band wire 13. The work of fixing to the above is performed by the reverse procedure of the above-described work of removing the binding wire 13. At this time, the binding wire 13 to be newly attached is bent in advance in a spiral shape corresponding to the winding shape around the high-voltage wire 12. Therefore, after the latching curved portion 13a of the new bind wire 13 is latched on the high-pressure pin insulator 14, the bind wire 13 is moved from the vicinity of the latching curved portion 13a to the end portion and the insulator shaft body portion 10 is moved. By forcibly turning the screw in the winding direction around the high-voltage line 12, the high-voltage line 12 can be attached in a wound state. Needless to say, when the bind wire 13 is attached to the high-voltage wire 12 in a wound state, the same effect as that of the attachment described above can be obtained.
[0031]
【The invention's effect】
As described above, according to the bind wire attaching / detaching tool of the present invention, the insulating operation rod is configured to rotate the support hook portion around the high-voltage line with the high-pressure wire engaged with the support hook portion in the latched state as a fulcrum. By operating the lever, the insulator shaft body part that rotates integrally with the support hook part forces the bind wire to the high-voltage line in the direction of winding or the direction opposite to the winding direction by the lever principle, and binds it. The wire can be wound or removed from the high voltage wire. Therefore, the attaching / detaching operation of the bind line can be performed stably without fear of slipping and easily without requiring a large operating force, and there is no possibility that the terminal cap is detached from the bind line during the attaching / detaching operation. In addition, the operation of sliding the attachment / detachment operation member along the high-voltage line and the operation of rotating the high-voltage line as a fulcrum can be continuously performed while the state where the support hook portion is latched to the high-voltage line is always maintained. Therefore, it is possible to perform the attaching or removing operation of the bind line in a short time.
[0032]
In addition, according to the bind wire attaching / detaching method using the bind wire attaching / detaching tool of the present invention, for example, in the bind wire removing operation, first, the prying portion of the insulator shaft body portion is connected to the end portion of the bind wire and the high voltage wire. If the end of the bind wire is removed from the high voltage line by rotating the insulator shaft body with the high voltage line as a fulcrum, The operation of sliding the attachment / detachment operation member along the high-voltage line and the operation of rotating the high-voltage line around the fulcrum can be continuously performed while keeping the state where the line is fitted, so that the binding line can be removed. Can be performed in a short time. In addition, since the lever shaft body is rotated on the principle of the lever with the high-voltage line as a fulcrum through the rotating portion that rotates about the axis perpendicular to the insulating operation rod, a large operating force is not required. Therefore, since the removal operation can be performed stably without sliding, there is no possibility that the terminal cap of the bind line is detached during the removal operation.

Removing only about one turn of winding around
A step of repeating a moving operation along the high-voltage line of the attaching / detaching operation member and a rotating operation around the high-voltage line a required number of times while maintaining the state where the high-voltage line is fitted in the rotation support part,
A bind line attaching / detaching method using a bind line attaching / detaching tool, wherein when the bind wire is attached to the high voltage wire in a state of being wound, the process at the time of removing is performed in the reverse procedure.
