The input shaft 21 is connected to the output shaft of a hydraulic motor (not shown) for driving the motorized tool 6 when the motorized tool 6 is mounted on the input shaft 21.

 The operation will be described below.

The electric wire peeling tool 10 includes a driven gear 44 of the peeling portion 40, as shown in FIG.
Notches 45 of rotors 45, 46, spacer 47 and cutter 48
a, 46a, 47a, and 48a, the coupler 70 of the polishing section 40, the rotor
Notches 70a, 71a, 72a and openings 73a of 71, 72 and polisher 73
Are aligned with the notches 31a and 32a (FIG. 4) of the housings 31 and 32, respectively. In this state, the wire stripping and polishing tool 10 is arranged beside the electric wire 100 and along the electric wire 100, and the electric wire 100 is taken into the center position of the housing 30 (first
1 to 13 and 16 to 19). At this time, the cutting edge 56a of the cutting blade 56 of the cutter 48 and the wire brushes 76 and 77 of the grinder 73 are
It is slightly separated from the surface of the skin 102 of the electric wire 100.

Next, when the hydraulic motor is normally rotated, the input shaft 21 of the skin removing tool 10 rotates, and the shaft 15 rotates via the bevel gears 23 and 25. The rotation of the shaft 15 causes the drive gear 37 (FIG. 5) to rotate, and the driven gear 44 to rotate via the idle gears 38 and 39, so that the peeling portion 40 and the polishing portion 41 are integrated with the driven gear 44. Rotates in the clockwise direction indicated by arrow C. With the rotation of the rotor 45, the head 51 of each bolt 51, 52
a and 52a slide in the holes 46d and 46e (Fig. 13) of the rotor 46 from one end to the other end. The rotor 46 is still stopped at this time.

When the rotation of the rotor 45 progresses and the bolts 51 and 52 reach the other ends of the holes 46d and 46e of the rotor 46 as shown in FIG. 15, the bolts 51 and 52 come into contact with and lock to the other ends of the holes 46d and 46e. And then the rotor
46 is rotatable together with the rotor 45. At this time, as shown in FIGS. 14 and 15, the electric wire 100 is rotatably sandwiched from both sides by the notch gear 44, the rotor 45, the spacer 47, and the rotor 46 so that the electric wire 100 cannot be deviated.

Further, the tip of the bolt 52 of the rotor 45 slides in the groove 48d of the cutter 48 from one end to the other end (FIG. 12) as the rotor 45 rotates, and the bolt 58 for supporting the cutter 48 on the rotor 46. Slides in the hole 47d of the spacer 47 from one end to the other end. The groove 48d of the cutter 48 has its radius reduced from one end to the other end as shown in FIG. 7, so that the groove 48d is provided with the bolt 58 as a fulcrum as the rotor 45 rotates. One end can be expanded radially outward. In response to this, the other end, that is, the cutting edge 56a of the cutting blade 56 moves inward in the radial direction and gradually begins to bite into the skin 102 of the electric wire 100.

Then, as shown in FIG. 14, when the head 52a of the bolt 52 reaches the other end of the groove 48d of the cutter 48, the cutting edge 56a of the cutting blade 56 is formed.
However, it cuts into the wire 102 by about the thickness of the skin 102. At this time, the cutting edge 56a is slightly separated from the core wire 101 of the electric wire 100, so that the core wire 101 is prevented from being damaged.
Incidentally, the rotation directions are opposite to each other because they are viewed from opposite directions in FIGS. 14 and 15.

Driven gear 44, rotors 45, 46, spacer 47, cutter 48
Rotates around the electric wire 100, and the cutter 48 starts to peel the skin 102 of the electric wire 100 with the cutting edge 56. At the same time, the peeling and polishing tool 10 is gradually moved in the direction of arrow A in FIG.
As a result, the cutter 48 spirally rotates around the electric wire 100 and gradually peels the skin 102 continuously. In this way, the skin 102 of the electric wire 100 is peeled off over a predetermined length.

On the other hand, at the time of peeling, the polishing device 73 of the polishing section 41 is used.
Is expanded, and the tips of the wire brushes 76, 77 are separated from the skin 102 of the electric wire 100. That is, when the polishing section 41 rotates in the clockwise direction indicated by the arrow C, the heads 81a and 82a of the bolts 81 and 82 are moved by the polishing pieces 7 of the polishing machine 73 as shown in FIG.
The insides of the grooves 74c, 75c of 4, 75 are moved to the positions shown by the solid lines, and the polisher 73 is expanded. As a result, the tips of the wire brushes 76, 77 of the polisher 73 are separated from the skin 102 of the electric wire 100, and the skin 102 is not damaged.

After stripping the electric wire 100, the bare core wire 101
Perform the polishing work. When the driving hydraulic motor is rotated in the reverse direction, the peeling section 40 and the polishing section 41 rotate in the counterclockwise direction indicated by the arrow CC. When polishing this core wire, the cutting edge of the cutter 48
The blade edge 56a of 56 returns to the position shown by the solid line in FIG.
Away from the skin 102 of. That is, when the peeling section 40 rotates counterclockwise as indicated by the arrow CC, the head 52a of the bolt 52 moves to the position shown by the solid line in the groove 48d of the cutter 48 as shown in FIG. The cutting edge 56a of the blade 56 is separated from the skin 102 of the electric wire 100. As a result, the cutting edge 56 does not damage the skin 102.

When the polishing section 41 rotates counterclockwise, the heads 81a and 82a of the bolts 81 and 82 fixed to the rotor 71 move from one end to the other inside the grooves 74c and 75c of the polishing pieces 74 and 75 of the polisher 73, respectively. Slide toward the end (Fig. 17). Each groove 74 of the polishing pieces 74, 75 of the polisher 73
As shown in FIG. 8, the radii of the c and 75c are increased as they go from one end to the other end, so that they rotate with the bolts 83 as fulcrums as the rotor 71 rotates.
6, 77 gradually abut on the core 101.

Then, as shown in FIG. 19, the head 81 of each bolt 81, 82 is
When the a and 82a reach the other ends of the grooves 74c and 75c of the polishing pieces 74 and 75, the wire brushes 76 and 77 are pressed against the core wire 101. still,
19 and 20 are viewed from the opposite directions, the directions of rotation are opposite.

The grinder 73 rotates around the core wire 101 together with the rotor 72, and begins to polish the surface of the core wire 101 with the wire brushes 76 and 77. At the same time, the peeling tool 10 is moved along the arrow A direction in FIG. This makes the polisher 73
Polishes the core wire 101 spirally and continuously. In this way, the core wire 10 of the portion of the wire 100 where the skin 102 is stripped off
Polish one.

After the polishing work of the core wire 101 is completed, the driving hydraulic motor is stopped, and the wire stripping and polishing tool 10 is connected to the wire 100.
Remove from This completes the work of stripping the skin 102 of the electric wire 100 and the work of polishing the core wire 101. Thus, at the time of electric power line, in the distribution work of the overhead distribution line which is in a live state, the work of stripping the corresponding distribution line and the work of polishing the core wire after the stripping are performed automatically and continuously. You can
