Description

  TECHNICAL FIELD The present invention relates to a sheath winding binding attachment / detacher, and in particular, for use in attaching or removing a binding wire to or from a high voltage wire to fix the high voltage wire to a high voltage pin insulator while being wound around the high voltage wire. The present invention relates to a bind winding attachment / removal device with a sheath winding.

  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 a 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.

Therefore, in recent years, a so-called “hot stick method” is employed in which a bind wire is wound or removed by remote operation using an insulating operation tool on a high-voltage wire in a live state. For example, a binding wire attaching / detaching tool described in Patent Document 1 is employed for attaching / detaching a bind wire by the “hot stick method”. The binding wire attaching / detaching tool described in Patent Document 1 includes an insulating operation rod 1 and an attaching / detaching operation member 2 fixed to the tip of the insulating operation rod 1. The detachable operation member 2 includes a base portion 3 fixed to the insulating operation rod 1 and a high-voltage wire 12 provided on the base portion 3 so as to be rotatable about an axis perpendicular to the insulation operation rod 1 and around which a bind wire 13 is wound. A hook portion 9 that is hooked on the support hook portion 9, and a direction in which the bind hook 13 is wound around the high-voltage line 12 when the support hook portion 9 rotates around the high-voltage line 12 or the winding direction. Is provided with an insulator shaft body portion 10 which acts to force the screw in the opposite direction.

  In addition, the wound binding attachment / detachment tool described in Patent Literature 2 has one end detachably coupled to the tip of the operation rod, and a base having a first rotation axis orthogonal to the axis of the operation rod at the other end, The first rotating shaft can be rotated on a virtual plane including an axis extension line of the operation rod or on a virtual plane close to the virtual plane in parallel, and is brought into contact with the peripheral surface of the electric wire. And an insulator body portion configured to exert an acting force in the circumferential direction of the wire on the winding binding with the contact point as a fulcrum. The bind hitter 45 shown in FIG. 13 described in Patent Document 2 has one end of a steel rod 48 having a circular cross section fixed to the axis of the base 46, the other end is bent into a substantially C shape, and the iron bar 48 is further closer to the base 46. It has the structure where the protrusion piece 47 was provided perpendicularly | vertically.

JP 2004-153900 A JP 2008-42990 A

In the binding wire attaching / detaching tool of Patent Document 1, the support hook portion 9 and the insulator shaft body portion 10 inserted between the high-voltage wire and the binding wire wound around the high-pressure wire are located at a position away from the axis of the insulating operation rod 1. Since it is formed, a moment is applied when the support hook portion 9 and the insulator shaft body portion 10 are inserted between the high-voltage line and the bind line, and it cannot be said that the usability is very good.
The invention related to Patent Document 2 is relatively lightweight, but the insulator body portion 20 protruding from the first rotating shaft 15 has a long distance to the curved portion 221 that acts on the binding line, and is movable when operated. Since the area is too large, it is difficult to fix the end of the bind wire in close contact with the overhead wire.
The bind hitter 45 shown in FIG. 13 of Patent Document 2 can be removed while turning the bind wire after the end of the bind wire wound around the high voltage wire is removed from the high voltage wire. It is difficult to loosen the end of the wire from the high voltage wire.
In consideration of the above circumstances, the present invention can be easily attached to a wire or the like from a wire or the like and attached to the tip of an operation rod without requiring a large operating force. An object of the present invention is to provide a cover-wrapping bind attachment / detacher that is small and has a simple structure that can improve work efficiency.
