Description

  The present invention relates to an indirect live wire work clip and an indirect live wire work clip assembly used to sandwich an electric wire, an insulation protector (for example, an insulating sheet), or the like.

  Conventionally, in indirect hot wire work, the high-voltage underline is connected to the high-voltage overhead wire via a branch connector. May be temporarily fixed in a state of being held (see Patent Document 1). Moreover, in indirect hot wire work, in order to prevent the electric shock accident of an operator, the charged part of an electric wire is covered with an insulation sheet (insulation armor), and the insulation sheet is a sheet of scissors for an indirect method (a clothespin) The sheet clip) may be fixed to the electric wire while being clamped by the sheet clip (see Patent Document 2).

  Both of these conventional wire clips and indirect method sheet scissors must be used in the state where the gripping part is sandwiched between the end arms of the insulating Yatco (the high voltage underline and the temporary fixing position of the high voltage overhead wire, or the insulating sheet) When the operator operates the handle of the insulated cable, the gripping part is released from the state of being sandwiched by the distal arm of the insulated cable, and the high voltage underline and the high voltage overhead cable are connected. It is temporarily fixed in a held state, or fixed in a state where an insulating sheet is sandwiched between charged portions of electric wires.

  However, both the conventional electric wire clip and the sheet scissors for indirect methods are transported to the use position with the gripping part sandwiched between the end arms of the insulating jacket, so there are obstacles during the movement to the use position. If it collides with (part of an aerial work vehicle, other indirect hot-wire tool, utility pole armor, etc.), it will be displaced from the tip arm of the insulated Yatco due to the impact at the time of collision, or it will be inoperable In some cases, the tip of the insulated Yatco slips off due to the impact of the. In such a case, since the conventional wire clip and the sheet scissors for the indirect method are again held in the correct posture by the tip arm of the insulating Yatco, there is a problem that the work efficiency of the indirect hot wire work is deteriorated. .

  In addition, the conventional sheet scissors for indirect methods open and close the mouth (upper and lower jaws) for holding the object to be fixed (for example, the insulating sheet) by the operator operating the handle of the insulating jacket. Therefore, the operator has to operate the handle while holding the operation bar of the insulated Yatco firmly, which is difficult for the operator.

  Therefore, the present invention provides an indirect live line work clip and an indirect live line work clip assembly that are excellent in operability without deteriorating the work efficiency of the indirect live line work.

  The present invention relates to an indirect hot wire work clip 1 made of an insulating resin material that is used to hold an object to be fixed 38 in an indirect hot wire work. The indirect hot wire working clip 1 according to the present invention includes an adapter 4 that is detachably fixed to a tip tool mounting portion 3 of a common operation rod 2 and a pair of branches that are bifurcated from the adapter 4 and face each other. Arm 5 and 5 and elastically deformable sandwiching pieces 7 and 7 fixed to one of the pair of arms 5 and 5 on the opposite inner surfaces 6 and 6 side, respectively. The one sandwiching piece 7 of the pair of arms 5 and 5 and the other sandwiching piece 7 of the pair of arms 5 and 5 are located adjacent to each other, and the adapter 4 is connected to the common operation rod 2. When the object to be fixed 38 is pressed between the sandwiching pieces 7 and 7 from the tip side of the sandwiching pieces 7 and 7 by being operated in a state of being fixed to the tip tool attaching portion 3 of the The object to be fixed is elastically deformed by the fixed object 38, receives the object to be fixed 38 between the both sandwiching pieces 7, 7, and elastically clamps the object to be fixed 38.

  Since the clip for indirect hot wire work according to the present invention is designed to fix the adapter to the tip tool mounting portion of the common operation rod, even if it collides with an obstacle during the movement to the use position, the common operation It does not deviate from the tip tool mounting portion of the rod or fall off from the tip tool mounting portion of the common operation rod, so that the work efficiency of indirect hot-line work is not deteriorated.

  In addition, the indirect hot-work work clip according to the present invention can receive the object to be fixed between the both holding pieces by elastically deforming both the holding pieces that hold the object to be fixed. The clamping piece can be clamped elastically, and there is no need to open and close both the clamping pieces (opening and closing the mouth), so the adapter is fixed to the tip tool mounting part of the common operation rod and the common operation rod is operated. Thus, the object to be fixed can be elastically held between the both holding pieces simply by pushing the object to be fixed between the holding pieces. As a result, the indirect hot-line work clip according to the present invention makes the indirect hot-line work easier and easier to operate than the case where the scissor mouth of the indirect construction method has to be opened and closed by the handle operation of the insulating jacket. Will improve.
