  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1-5 is a figure which shows 1st Embodiment of the electric wire cutting work auxiliary tool which concerns on this invention.

  In FIG. 1, an electric wire cutting work auxiliary tool (hereinafter also simply referred to as an auxiliary tool) 10 is, for example, a distribution line such as a so-called edge line or pull-down line that has both ends fixed to nearby portions and is not subjected to large tension. It is a tool used when cutting D, and is a connecting part 11 attached in a posture parallel to the distribution line D, a holding part 12 that holds two portions in the vicinity of the cutting part of the distribution line D, and a connection part 11 And support portions 13 that respectively support the holding portions 12 so as to hold the distribution lines D at positions separated from the connecting portions 11.

  The connection part 11 and the support part 13 are cylindrical members having a plurality of slits 11a and 13a opened for weight reduction, and one end side of the connection part 11 at the connection part located on the left side in FIG. The disc-shaped connecting end portion 22 formed on the base end side of the support portion 13 is opposed to the disc-shaped connecting end portion 21 that is formed in the shape and has the axis aligned with the extending direction thereof. The bolt 24 penetrates the connecting end 22 and is screwed into a female screw 21a formed in the connecting end 21 so that the connecting portion is rotatably screwed and connected.

  Thereby, in the left connection part in FIG. 1A, the support part 13 is connected rotatably in the front and back direction in FIG. 1A around the one end side of the connection part 11 (see FIG. 3).

  At the connecting portion of the connecting portion 11 and the support portion 13, a friction plate (sliding member) 23 is fixed to the connecting end portion 21 side of the connecting portion 11 so as not to rotate, and is relatively rotated to the connecting end portion 22 of the support portion 13. Faces freely. The connecting end portion 22 of the support portion 13 has a pair of support plates 25 erected in parallel with the extending direction of the connection portion 11 and a tongue-like shape that is movably sandwiched between the support plates 25. A member (abutting member) 26 is provided, and the tongue-like member 26 penetrates through the support plate 25 and is rotatably attached to the rotary shaft 28 in a direction away from both ends of the rotary shaft 28. The extending lever member 27 is integrally formed so as to rotate integrally.

  Accordingly, at the left connecting portion in FIG. 1A, for example, the lever member 27 is gripped by the YATCO 100 shown in FIG. The member 26 can be moved toward and away from the friction plate 23, and the support member 13 is connected to the connecting end 21 side of the connecting portion 11 by fixing the tongue-like member 26 against the friction plate 23. The end 22 can be positioned and locked so as not to be relatively rotatable. That is, the lever member 27 and the tongue-like member 26 and the friction plate 23 constitute a lock mechanism.

  Here, as shown in FIG. 4, the Yatco 100 holds the object by transmitting the operating force via the holding part 110 that holds the object, the support bar 131 that the operator holds and supports, and the transmission bar 132. And a handle 122 for operating the section 110. In this YATCO 100, a movable member 112 connected to a transmission rod 132 by operating a handle 122 with respect to an immovable member 111 of a gripping portion 110 fixed to a support rod 131, with a rotation shaft 113 as a center. By rotating, the object such as the lever member 27 can be gripped between the tip portions 111a and 112a of the members 111 and 112 of the grip portion 110. The Yatco 100 includes an umbrella cover 134 for dripping moisture from the gripping side, and an umbrella cover 135 indicating a limit position where the work can be safely performed in consideration of insulation from the gripping side. Insulation is secured by being made entirely of an insulating material such as plastic or rubber material, and it is not indirectly working directly on the live parts wearing protective clothing, but indirectly while ensuring insulation. The so-called indirect hot wire method can be executed.

  Moreover, the connection part 11 and the support part 13 are a connection part located in the right side in Fig.1 (a), and a pair of disk-shaped connection end parts 31 currently formed in the other end side of the connection part 11 are support parts. The disc-shaped connecting end portion 32 formed on the base end side of 13 is sandwiched, and the connecting end portions 31 and 32 are rotatably connected by passing through the bolt 33a and screwing into the nut 33b. Has been.

  Thereby, in the right connection location in FIG. 1A, the support portion 13 is rotatably connected within the plane in FIG. 1A with the other end side of the connection portion 11 as the center (see FIG. 2). ).

  In the connection part of this connection part 11 and the support part 13, the included angle which the main-body parts in which the slits 11a and 13a are formed abuts on the adjacent part of the connection end parts 31 and 32 and forms between each other is approximately 90 degrees. As described above, the rotation is relatively limited. Further, the connecting portion 11 and the support portion 13 are biased in a direction in which a torsion spring 34 is housed between the connecting end portions 31 and 32 so as to approach each other (a direction of 90 degrees).

  1A, the elastic force of the torsion spring 34 is obtained even when the support portion 13 rotates in the direction of widening the included angle with respect to the connection portion 11 around the connection end portions 21 and 22. To return to the direction of return.

  The holding part 12 is connected to the distal end side of the support part 13 in a posture orthogonal to the distribution line D, and the support part 13 is fixed to the outer surface on one end side of the cylindrical member 41. Projecting portions (separating members) 42a and 42b that are separated from each other in the extending direction of the distribution line D, and extend in the length direction of the tubular member 41. A hook-shaped portion (intermediate member) 45 that is exposed to the outside so as to be located in the middle of the protrusion-shaped portions (separating members) 42a and 42b from within the formed slit 41a, and moves along the extending direction; It has.

  The cylindrical member 41 has a cylindrical portion 43 coaxially attached to one end side thereof, and a male screw member 44 that rotates coaxially with the cylindrical portion 43 is internally provided therein. A moving mechanism of the hook-shaped portion 45 is mounted by screwing a female screw groove 45a formed on the proximal end side of the hook-shaped portion 45 into the thread 44a of the male screw member 44.

  Accordingly, the holding portion 12 is connected to the cylindrical portion 43 on one end side of the cylindrical member 41 with the distal end side of the insulating operation rod 200 shown in FIG. With the rotation of the member 44), the hook-shaped portion 45 can be moved in a direction close to the protrusion-shaped portions 42a and 42b. For this reason, the distribution line D in a posture parallel to the connecting portion 11 positioned on the distal end side of the support portion 13 is wrapped so as to apply a load that causes the hook shape portion 45 to abut and bend between the protrusion shape portions 42a and 42b. It can be securely clamped (in a state in which it cannot be detached), and the hook-shaped portion 45 is moved in the separating direction to form a separation space with the projection-shaped portion 42 to be clamped (held). Can be removed from the state.

  Here, the cylindrical part 43 has an insertion notch part 43a from the rear end face side toward the front end side by opening the peripheral face of the cylindrical shape into a substantially T-shape, and this insertion. A pair of engagement notches 43b that bends continuously on both sides in the orthogonal direction of the notches 43a are formed.

  On the other hand, as shown in FIG. 5, the insulating operation rod 200 is provided with two protrusions on the side surfaces on the opposite sides of the cylindrical tip portion, thereby forming two notches in the cylindrical portion 43. A pin 201 that can be inserted into and engaged with the portions 43a and 43b, a protrusion 202 that is disposed on the tip surface of the tip portion and is urged in a protruding direction by a built-in spring (not shown), A grip 203 that is screwed into a screw shape (not shown) engraved on the side surface and can be advanced and retracted, and a grip portion 204 on the base end side that is gripped by an operator and is provided with a slipper that can be replaced with a non-slip material. And. As a result, the insulating operating rod 200 inserts the tip portion into the cylindrical portion 43 and sinks the protrusion 202 against the elastic force of the built-in spring, while allowing both pins 201 to enter the notches 43a and 43b. When the force to be entered is released after the rotation, the protrusion 202 protrudes by the elastic force of the spring and pushes out the cylindrical portion 43, thereby further bending the engagement notch 43 b from the extending direction. The pin 201 can be engaged with the pin 201 so as not to be detached. The insulating operation rod 200 can be locked so that the pin 201 is not detached from the end of the engagement notch 43b and rotated by rotating the grip 203 toward the cylindrical portion 43. The insulating operation rod 200 also has umbrella covers 205 and 206 attached to the middle portion, and is made of an insulating material such as plastic as a whole to ensure insulation. 205 drops water from the auxiliary tool 10 side, and the umbrella cover 206 on the base end side indicates a limit position where the work can be safely performed, thereby ensuring safety when working.

  The holding portion 12 is a ball formed at the tip of a support rod 37 protruding from the outer surface of the tubular member 41 in a spherical space portion 36 a formed in the block-shaped portion 36 on the tip side of the support portion 13. The support rod 37 is inserted into the ball portion 38 that is swingably connected to the distal end side of the support portion 13 by pushing the portion 38 and is swingably accommodated in the spherical space portion 36a. Within the allowable swing range and between the hook-shaped portion 45 and the protrusion-shaped portion 42 within the allowable swing range until the cylindrical member 41 of the holding portion 12 and the block-shaped portion 36 of the support portion 13 abut against each other. It is allowed to swing while maintaining the state of holding the distribution line D. That is, the support rod 37 and the ball portion 38 on the outer surface of the cylindrical member 41 of the holding portion 12 and the spherical space portion 36a in the block-shaped portion 36 of the support portion 13 constitute a play mechanism, and a distribution line D described later. Is allowed to swing at the time of cutting, and restricts the distribution line D from moving too much.

  Thereby, the auxiliary tool 10 employs an indirect hot wire method, attaches the tip end portions of the insulating operation rods 200 to the cylindrical portions 43 of the both holding portions 12, and covers both sides of the cut portion of the distribution line D to be cut. It can be located between the protrusion-shaped part 42 and the hook-shaped part 45, and the distribution line D is sandwiched between the protrusion-shaped part 42 and the hook-shaped part 45 by rotating the insulation operating rod 200 in this state. Can be attached. The insulating operation rod 200 is pushed or pulled with respect to the distribution line D without using the grip 203, so that the projection 202 is sunk in the cylindrical portion 43 and the pin 201 is removed from the notches 43a and 43b. It can be moved in the direction of detachment, and the tip can be attached to and detached from the cylindrical portion 43.

  In this state, for example, a hydraulic cutting (not shown) is performed so that the distribution line D sandwiches the distribution line D held by the holding unit 12 at a position separated from the connection unit 11 of the auxiliary tool 10 via the support unit 13. It is possible to perform cutting work by positioning even a blade with a blade thickness like a tool. At this time, as shown in FIG. 2, the connection end portions 31 and 32 are connected to the bolts 33 a at the connection portion of the connection portion 11 and the support portion 13, as shown in FIG. 2. While rotating relatively around the nut 33b, the ball portion 38 on the holding portion 12 side slides in the spherical space portion 36a of the block-shaped portion 36 on the support portion 13 side, so that the support rod 37 (projection-shaped portion). 42 and the hook-shaped portion 45) are allowed to swing, and the cutting of the distribution line D by the cutting tool having a blade thickness is not hindered.

  Thereafter, the distribution line D separates the tongue-shaped member 26 from the friction plate 23 by picking the lever member 27 between the tip portions 111a and 112a of the gripping portion 110 of the YAT 100 and rotating it around the rotation shaft 28. By releasing the lock, the support portion 13 can be rotated around the bolt 24 of the connecting portion 11. For this reason, as shown in FIG. 3, the distribution line D is a cut end of the distribution line D that is sandwiched between the protrusion-shaped portion 42 and the hook-shaped portion 45 by rotating the holding portion 12 to the left or right. The parts can be separated from each other by being separated from each other, and the lever member 27 is picked and rotated again with the YATCO 100, and the tongue-like member 26 is brought into contact with the friction plate 23 to be in a locked state. It is possible to maintain the insulating state by restricting the end portion that has been moved freely.

  As described above, in this embodiment, the two places sandwiching the cut portion of the distribution line D can be maintained in the connected state while being held by the holding portion 12 at the tip of the support portion 13 at a position separated from the connecting portion 11. Using a space between the connecting portion 11 and the support portion 13 secured between the distribution line D and a cutter having a blade thickness such as a hydraulic cutting tool, the distribution line D is inserted. The cutting work can be executed with At this time, the cut end portion of the distribution line D is not hindered from swinging in the direction of separation by the blade thickness of the blade. Therefore, even if it is thick to supply power like the distribution line D, it is possible to perform the cutting operation while holding the vicinity of the cutting end portion, and the cutting end portion freely swings. It is possible to prevent a ground fault from occurring.

  Here, in the present embodiment, a mechanism for rotating the tongue-shaped member 26 with the lever member 27 is adopted, but the present invention is not limited to this. For example, as shown in FIG. A flat plate member 57 that can be picked by the Yatco 100 at the end of the shaft 28 may be fixed to both ends and rotated. Also, as shown in FIG. An orthogonal portion 67 extending in the orthogonal direction with respect to the member 26 is integrally formed, and a rod-shaped member 68 that can be picked by the Yatco 100 is extended at both ends of the orthogonal portion 67 and rotated. May be.

Since the present embodiment is configured in the same manner as the above-described embodiment, the same components are denoted by the same reference numerals and the characteristic portions will be described.

  In FIG. 8, the electric wire cutting operation assisting tool 10 is constructed by including a connecting portion 11, a holding portion 12, and a supporting portion 13, and the connecting portion 11 in the present embodiment does not rotate relatively coaxially. In this way, the angular or elliptical cylindrical members 71 and 72 are combined to be a stretchable mechanism.

  Specifically, the connecting portion 11 is formed so that the cylindrical member 72 can be inserted into the cylindrical member 71, and a nut 73 is fixedly provided on the outer surface side of the cylindrical member 71. The entire length can be fixed by screwing a bolt 74 having a knob portion 74 a to the nut 73 and abutting the tip portion against the tubular member 72. Moreover, this connection part 11 can be expanded-contracted with the state attached to the distribution line D by picking the knob part 74a with the Yatsuko 100 etc., and rotating the volt | bolt 74.
