  At least the following matters will become apparent from the description of this specification and the accompanying drawings.

  A working rod 300 according to this embodiment is shown in FIG. FIG. 1 is an enlarged view of the tip of the work bar 300. The working bar 300 according to the present embodiment is configured by attaching a tip tool (tool) 100 to the tip of the hot stick 200.

  As will be described later, the work bar 300 is used when performing the construction for attaching the fender 400 to the armrest of the utility pole.

  As shown in FIG. 1, the work bar 300 includes a hot stick 200 and a tip tool 100. As will be described in detail later, the working rod 300 engages the connecting pin 211 formed on the tip of the hot stick 200 with the connecting pin fixing portion 132 formed on the tip tool 100 and rotates the lock nut 220 in the locking direction. By doing so, the tip tool 100 and the hot stick 200 are combined.

  The overall configuration of the hot stick 200 is shown in FIG. The hot stick 200 is a substantially cylindrical rod having a tip tool mounting portion (tip portion) 210, a lock nut 220, a draining collar 230, an insulating rod 240, and a grip 250. Yes.

The grip 250 is a portion that is gripped by an operator.
The insulating rod 240 is an insulating resin rod.
The draining collar 230 prevents the water droplets from reaching the grip 250 when the water droplets flow down the surface of the hot stick 200.

  The tip tool mounting portion 210 is a portion to which the tip tool 100 is mounted. The tip tool mounting portion 210 has a substantially cylindrical shape, and a connecting pin 211 for coupling to the tip tool 100 is formed on the outer surface of the tip tool mounting portion 210 so as to protrude in the radial direction.

  The lock nut 220 is configured to be rotatable around the central axis of the hot stick 200. When the lock nut 220 is rotated, the lock nut 220 can be moved in the extending direction of the hot stick 200.

  When the lock nut 220 is rotated in the locking direction in a state where the connecting pin 211 of the tip tool mounting portion 210 is mounted on the connecting pin fixing portion 132 of the tip tool 100, the lock nut 220 moves in a direction approaching the tip tool 100, The connection between the tip tool 100 and the hot stick 200 is strengthened. Conversely, when the lock nut 220 is rotated in the release direction, the lock nut 220 moves in a direction away from the tip tool 100 and the connection between the tip tool 100 and the hot stick 200 is loosened.

  The hot stick 200 according to the present embodiment is lightweight because the insulating rod 240 is made of resin, and can be operated with one hand.

  Next, the external configuration of the tip tool 100 according to the present embodiment is shown in FIGS. 3 and 4. The tip tool 100 includes a substantially cylindrical pedestal portion 120 mounted on the tip tool mounting portion 210 of the hot stick 200, and a metal fitting suction portion 110 extending in a bar shape from the upper surface of the pedestal portion 120. Yes.

  The pedestal portion 120 is a substantially cylindrical portion having an open bottom surface on the side attached to the hot stick 200. In addition, on the side surface of the pedestal portion 120, a slit (connection pin slit 130) that is opened in a substantially T shape so as to continue from the opening on the bottom surface is formed.

The connection pin slit 130 includes a connection pin insertion portion 131 and a connection pin fixing portion 132.
The connecting pin insertion portion 131 is opened so as to cut the side surface of the pedestal portion 120 from the bottom surface to the top surface of the pedestal portion 120, and further branched to the left and right to open so as to cut the side surface of the cylinder in the circumferential direction. It is a T-shaped slit.
The connection pin fixing part 132 is a part formed so as to widen the opening in the direction toward the bottom surface of the pedestal part 120 at both ends of the opening branched to the left and right of the connection pin insertion part 131.

  The metal fitting adsorbing part 110 is a part that extends from the pedestal part 120 in a rod shape and is magnetized at the tip. The metal fitting adsorbing portion 110 includes an extending portion 112 that extends in a rod shape from the upper surface of the pedestal portion 120, and a magnetic force generating portion 111 that generates a magnetic force at the distal end portion of the extending portion 112.

  The metal fitting adsorbing part 110 extends so as to be inclined with respect to the longitudinal direction of the hot stick 200. For example, as shown in FIG. 4, the extending portion 112 extends in the direction (C1) along the extending direction (longitudinal direction) of the hot stick 200 when the tip tool 100 is mounted on the hot stick 200, and the extending portion 112. Is formed so as to extend in the direction (C2) inclined with respect to the extending direction (C1) of the hot stick 200. In the example illustrated in FIG. 4, the extending portion 112 is configured to bend by an angle A1. As a result, workability when using the work bar 300 can be improved.

  A magnetic force generator 111 that generates a magnetic force capable of adsorbing metal is formed at the distal end of the extending portion 112. The magnetic force generator 111 is formed of a magnetic member such as a magnet.

  When the extending portion 112 is formed of a ferromagnetic material such as iron, cobalt, or nickel, the magnetic force generating portion 111 may be formed by magnetizing the distal end portion of the extending portion 112.

  Also, as shown in FIG. 4, the tip surface of the magnetic force generator 111 is the tip of the extension 112 so that the tip of the bracket suction part 110 is in the direction along the extension direction (C1) of the hot stick 200. It may be formed so as to face a direction inclined by an angle A2 with respect to the stretching direction (C2). That is, in this case, the tip tool 100 combines the bending angle A1 of the extending portion 112 and the inclination angle A2 of the leading end surface of the metal fitting suction portion 110 so that the direction of the front end surface of the metal fitting suction portion 110 extends the hot stick 200. It is formed so as to face the direction along the direction. This makes it possible to improve workability when using the work bar 300.

  In addition, the tip tool 100 according to the present embodiment is configured such that the pedestal portion 120 and the extending portion 112 are formed by, for example, machining of aluminum, and the magnetic force generated by a ferromagnetic material or a magnet at the distal end portion of the extending portion 112. It is formed by attaching the part 111. By setting it as such a structure, the tip tool 100 can be formed lightweight. Further, it is possible to reduce the weight of the work bar 300 formed by attaching the tip tool 100 to the hot stick 200.

  Next, the work bar 300 is configured by mounting the tip tool 100 on the tip of the hot stick 200, and the work bar 300 is used when the bar protection device 400 is mounted on the arm bracket 510 of the utility pole 500. As shown in FIG. FIG. 6 shows an external configuration of the anti-barrier device 400 attached to the arm metal 510.

  As shown in FIG. 5, the brace 510 has a prismatic shape and is attached to the utility pole 500 so as to extend in the horizontal direction. Although not shown in FIG. 5, various on-pillar equipment such as distribution lines, insulators, and switches are attached to the brace 510.

  Next, as shown in FIG. 6, the nesting device 400 includes a nesting tree 410 and a brace fixing part 420.

The nesting tree 410 includes a supporting bar 411 extending in the vertical direction and nesting branches 412 attached in multiple stages radially from the supporting bar 411.
The nest-preventing tree 410 is configured to radially expand the resin-made nest-preventing branches 412 from the support bar 411 so that wild birds such as crows and pigeons approach the vicinity of the nest-preventing tree 410. It is configured not to come. In addition, when these wild birds try to nest on the arm metal 510 and drop the material of the nest such as a tree branch on the arm metal 510, the nest branch 412 repels the material of the nest around, Nesting on the brace 510 is prevented. Further, since the nest branch 412 is made of a flexible resin, it is difficult for birds to stop on the nest branch 412.

The brace fixing part 420 is a metal fitting for attaching the fender 400 to the brace 510 of the utility pole 500.
The arm metal fixing part 420 includes a first fixing arm (first metal fitting) 421 and a second fixing arm (second metal fitting) 425.

The first fixing arm 421 includes a support shaft fixing portion 423 that is fixed to the support bar 411 of the nest tree 410, and a plate-like first fixing device that extends horizontally from the support shaft fixing portion 423 and bends downward. 422.
The first fixture 422 is formed to have a first extending portion 422A extending in the horizontal direction from the support shaft fixing portion 423 and a second extending portion 422B extending downward from the tip of the first extending portion 422A. Has been. A notch groove 424 is formed in the second extending portion 422B.

On the other hand, the second fixing arm 425 is movably attached to the first extending portion 422A, extends downward, and then bends in the horizontal direction. And a metal plate 427 mounted on the second fixing tool 426 so as to penetrate the bolt, a bolt 428, and a washer 429.
The second fixture 426 is movably attached to the first extending portion 422A and extends downward, a third extending portion 426A that extends downward, a fourth extending portion 426B that extends horizontally from the tip of the third extending portion 426A, It is formed to have.

  As shown in FIG. 5, when attaching the nest protector 400 to the arm bracket 510, one of the workers (not shown) finally holds the second extending portion 422 </ b> B of the nest protector 400 with the arm 600, and From the scaffolding on the lower power pole 500 or the gondola of the aerial work platform, lift the nest protector 400, and firstly extend the first extending portion 422A extending horizontally along the upper surface of the brace 510 and downward The nest protector 400 is placed on the arm metal 510 so that the second extending portion 422B to be extended extends along the side surface of the arm metal 510 (the first side surface intersecting the upper surface of the arm metal 510).

  Then, another worker (not shown) uses the work rod 300 according to the present embodiment from a scaffold on the power pole 500 below the arm bracket 510 or a gondola of an aerial work vehicle to use the second fixed arm. The metal plate 427 of 425 is adsorbed to the metal fitting adsorbing part 110 formed at the tip of the work bar 300.

  Then, by moving the work bar 300 while the metal plate 427 is adsorbed to the metal fitting adsorbing part 110, the third extending part 426A extending freely downward from the first extending part 422A is moved to the second side surface of the arm metal 510. The fourth extending portion 426B extending in the horizontal direction along the (side surface opposite to the first side surface) is aligned with the lower surface of the arm metal 510 (relative to the upper surface of the arm metal 510), and then the metal plate 427 is attached. The fourth extending portion 426B is inserted into the notch groove formed in the second extending portion 422B while being sandwiched between the second extending portion 422B and the washer 429 and the bolt 428.

  In this state, the metal fitting portion 110 is removed from the metal plate 427, and the bolt (clamping tool) 428 is tightened by using another working bar such as a bark 600 or an indirect ratchet, whereby the metal plate 427 is attached to the second extending portion 422B. Combine by pressing.

  Thereby, the nest protector 400 is attached to the brace 510. FIG. 7 shows a state in which the nest protector 400 is attached to the brace 510.

  Note that the work of attaching the nest protector 400 to the brace 510 may be performed by two persons as described above or by one person.

  As described above, according to the working rod 300 according to the present embodiment and the tip tool 100 provided at the tip of the working rod 300, the mounting bracket for mounting the bullproof device 400 on the arm metal 510 is magnetically attached. Therefore, it is possible to reduce the work load when operating the metal fitting, and it is possible to facilitate the work of attaching the nest protector 400 to the arm bracket 510.

  In particular, on the power pole 500 where such work is performed, cables such as distribution lines and telephone lines are stretched, and pole transformers, switches, radio base stations, and other various pole equipment are installed. However, according to the work bar 300 and the tip tool 100 according to the present embodiment, the orientation of the metal fitting and the work position of the operator Since the bracket can be easily moved without being affected by the location where the bracket is gripped, interference with the bracket, etc., it is possible to greatly reduce the work burden and improve the safety of the work. Become.

  In addition, since the tip tool 100 according to the present embodiment is configured to be detachable from the hot stick 200, the tip tool 100 is removed from the hot stick 200 after the work is completed and replaced with another tip tool such as an indirect ratchet. Can also be done easily.

  In addition, since the working bar 300 according to the present embodiment is lighter than an insulating barb or the like, it is possible to work with one hand, and workability can be improved.

  Further, the bracket suction portion 110 of the tip tool 100 attached to the tip portion of the work bar 300 has a direction in which the vicinity of the tip portion of the bracket suction portion 110 is inclined with respect to the extending direction of the hot stick 200 (for example, as shown in FIG. 4). It is formed to extend at an angle A1).

  Thereby, when attaching the insect guard 400 from the lower side of the arm bracket 510, the front end surface of the metal fitting adsorbing part 110 can be easily faced to the metal plate 427. Therefore, the magnetic force generating part 111 and the metal plate The contact area with 427 is increased, and the metal plate 427 can be more firmly adsorbed to the work bar 300. For this reason, while operating the metal plate 427 using the work bar 300, the metal plate 427 can be made difficult to come off from the metal fitting adsorbing portion 110 of the work bar 300, so It is possible to further facilitate the mounting operation.

  Furthermore, as described with reference to FIG. 4, the front end surface of the metal fitting adsorbing portion 110 is in the direction along the extending direction (C1) of the hot stick 200 so that the front end surface of the metal fitting adsorbing portion 110 extends in the extending portion. It may be formed so as to face a direction inclined by an angle A2 with respect to the extending direction (C2) of the tip end portion of 112.

  This makes it easier to make the front end surface of the metal fitting adsorption part 110 face the metal plate 427 when attaching the anti-barrier device 400 from below the arm bracket 510. The contact area with 427 is increased, and the metal plate 427 can be more firmly adsorbed to the work bar 300.

  Further, the tip end portion of the metal fitting adsorption portion 110 may be configured by attaching or bonding a magnet for generating a magnetic force to the extending portion 112. Thereby, the tip tool 100 and the work bar 300 according to the present embodiment can be easily manufactured.

  When the extending portion 112 is formed of a ferromagnetic material such as iron, nickel, or cobalt, the magnetic force generating portion 111 may be formed by magnetizing the distal end portion of the extending portion 112. Thereby, since the magnetic force generation part 111 can be integrally formed with the extending | stretching part 112, it becomes possible to manufacture the tip tool 100 more firmly.

Moreover, you may comprise so that the cover may be mounted | worn at the front-end | tip part of the metal fitting adsorption | suction part 110 so that this front-end | tip part may be covered.
With this cover, for example, it is possible to prevent an accident in which an operator accidentally comes into contact with the metal fitting adsorbing portion 110 during work and is injured. Alternatively, rust can be prevented when the metal fitting adsorbing portion 110 is formed of a ferromagnetic material such as iron. In addition, you may comprise simply this cover with the vinyl tape wound so that the front-end | tip part of the metal fitting adsorption | suction part 110 may be covered.
