Description

  The present invention relates to a tape winding tip tool capable of easily winding a tape around a member such as an electric wire.

  For electrical facilities such as an electricity supplier, work may be performed in an energized state in order to avoid a power outage. In live work such as electric wires, for example, an insulating cover called a wire protection tube is attached to the electric wires in the vicinity of the work area, and the insulating cover is fixed to the electric wires via an adhesive tape. When attaching an insulating cover with adhesive tape, it is necessary to pull the adhesive tape lead-out part firmly around the insulating cover while pulling the roll-like adhesive tape lead-out part and applying tension to the adhesive tape drawer part. Become.

  13 to 15 show an outline of a conventional operation of winding an adhesive tape around an electric wire. As shown in FIG. 13, the roll-shaped adhesive tape 100 is wound around the electric wire 101 using an indirect hot wire gripping tool 50 in a state where the leading end of the lead-out portion 100 c of the adhesive tape 100 is wound around the electric wire 101. This is done by moving the tape 100 around the electric wire 101. Specifically, the operation rod 55 of the indirect hot-line gripping tool 50 is operated, and the adhesive tape 100 is gripped from the side by the grip portion 51 including the pair of gripping arms 52 and 53, and then the indirect hot-line gripping tool 50. Thus, the drawing portion 100c of the pressure-sensitive adhesive tape 100 is wound around the electric wire 101 while applying tension to the drawing portion 100c of the pressure-sensitive adhesive tape 100.

  As shown in FIG. 14, in the conventional winding operation of the adhesive tape 100 around the electric wire 101, the roll-shaped adhesive tape 100 is pulled forward, the adhesive tape 100 is lifted forward, and the adhesive tape 100 is moved above the electric wire 101. It is necessary to repeat the operation of releasing the adhesive tape 100 beyond the electric wire 101 and moving the adhesive tape 100 moved to the inner side of the electric wire 101 and pulling it downward. And it winds, moving the adhesive tape 100 little by little to the right direction or the left direction so that the half in the width direction of the drawer | drawing-out part 100c of the adhesive tape 100 may overlap.

  Conventionally, the following technique is known as an example of a technique for winding an adhesive tape around an electric wire (see, for example, Patent Document 1). The tape winding tip tool of Patent Document 1 has a pair of tape support rods for holding a roll-shaped tape, and the support rods can advance and retreat with each other while being kept parallel.

Japanese Patent No. 4633014

  However, the winding operation of the adhesive tape 100 shown in FIGS. 13 to 15 around the electric wire 101 is performed so that the axis of the open / close fulcrum shafts of the pair of holding arms 52 and 53 in the indirect hot wire holding tool 50 is orthogonal to the laying direction of the electric wire 101. Therefore, it is necessary to grip the adhesive tape 100 while keeping the indirect live-line gripping tool 50 in the horizontal orientation. In addition, the operation of winding the adhesive tape 100 around the electric wire 101 requires a continuous operation of holding, pulling, winding, and releasing the adhesive tape 100 in the above-described posture, and it is difficult to continue the operation in that posture. There is also a problem that the wrist of the worker is burdened.

  Further, as shown in FIG. 15, in a state where the adhesive tape 100 is sandwiched between the indirect live-line gripping tools 50, the gripping surfaces of the gripping arms 52 and 53 and the side surfaces of the adhesive tape 100 due to the structure of the indirect live-line gripping tool 50. A gap Z is generated between the adhesive tape 100 and the adhesive tape 100 is difficult to grasp sufficiently. For this reason, when the adhesive tape 100 is pulled, the adhesive tape 100 rotates in the unwinding direction, so that the adhesive tape 100 cannot be sufficiently stretched and cannot be wound around the winding member with a large tension. .

  Further, in order to wrap the adhesive tape 100 around the electric wire 101, it is necessary to release the adhesive tape 100 once above the electric wire 101 and to change the adhesive tape 100. However, when the adhesive tape 100 is released, the adhesive tape 100 rotates horizontally. There is a problem that the adhesive surfaces of the adhesive tape 100 are attracted to each other.

  In the tape winding tip tool of Patent Document 1, when the tape is released above the electric wire, it is necessary to pull out the tape holding bar from the tape. Therefore, the entire indirect hot wire gripping tool to which the tape winding tip tool is attached is laterally moved. An operation to move is required. As described above, since the tape winding operation needs to repeat the operations of holding, pulling, winding, and releasing the tape, in the operation using the tape winding tip tool of Patent Document 1, the tape holding bar is pulled out from the tape. Therefore, the operation of moving the entire indirect hot-line gripping tool in the horizontal direction must be repeatedly performed, which increases the burden on the operator.

  Therefore, the present invention can remove the roll tape from the tape holding portion without moving the entire indirect hot wire gripping tool in the lateral direction, and reduces the labor when winding the tape around a member such as an electric wire. An object of the present invention is to provide a tape wrapping tip tool that can be used.
