Prior Art) Recently, attempts have been made to attach overhead power distribution lines to cross arms of poles via discharge clamps to prevent accidents caused by lightning strikes. To install such a discharge clamp, the insulator that conventionally attaches the overhead power distribution line to the cross arm is removed, and then the discharge clamp is attached. Recently, it has been proposed to safely carry out live wire work on pillars using robots, but in this case, a nut attachment/removal tool is required to be attached to the tip of the robot arm. The nut to which the insulator or discharge clamp is attached must be moved forward and backward while rotating the tool body that engages with this nut.

とができるようになっている。(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show an overhead distribution line nut attachment/removal tool lO according to the present invention, and FIG. This nut attachment/detachment tool 10 for overhead distribution lines, which shows the state of use of the nut attachment/detachment tool for electric wires, has a nut attachment/detachment tool main body 12 consisting of a cylindrical wrench for attaching/detaching a nut for fixing an insulator or the like that supports an overhead distribution line (not shown). and the tool body 12 to the vicinity of the overhead power distribution line.
A fixed frame 16 having a flange 16a is attached to a robot arm 14 (see Fig. 3) that moves the robot arm, and a tool body 12 is slidably supported on this fixed frame 16, and the tool body 12 is attached to a nut. The movable frame 18 is provided with a movable frame 18 so as to move forward and backward, and a linear drive source 20 consisting of an air cylinder attached to the movable frame 18 and driving the movable frame 18 so as to slide on the fixed frame 16. As shown in FIG. 2, the linear drive source 20 is attached to the movable frame 18 via an angle bracket 20a, and a clevis body 20C provided at the tip of the piston rod 20b of the linear drive source 20 connects the fixed frame 16. It is engaged with the arm 18b, and the linear drive source 2
By supplying air to the cylinder 0, the cylinder body moves in the axial direction relative to the fixed piston rod 20b and slides on the movable frame 18. Tool body 12
is connected via a universal joint 26 to a drive shaft 24 rotatably supported by bearings 22, 22' provided on the movable frame 18, and an air motor for rotationally driving the drive shaft 24 is connected to the movable frame 18. A fluid motor 28 such as the one shown in FIG. Note that the reference numeral 29 is a silencer for the fluid motor. This fluid motor 28 is decelerated @30. It is connected to the drive shaft 24 by a pulley-belt mechanism 32. still,
As can be seen from FIG. 1, the universal joint 26 can swing vertically and horizontally with respect to its axis by a spring 34 so that the tool body can elastically engage the nut. .

電クランプに締付けられてこれを固定する。Next, we will explain how the nut attachment/removal tool of the present invention is used.9 For example, when loosening a nut that fixes the insulator 26 or the discharge clamp 38 that supports an overhead power distribution line, first the air cylinder that is the linear drive source 20 is in the extended state. the tool body 12 to this nut 38 by operating the robot arm 14.
When approaching, the tool body 12 is engaged with this nut 38 to complete preparation for work.Next, while driving the fluid motor 28, the air cylinder, which is the linear drive source 20, is gradually deflated. In this way, the tool body 12 moves back while loosening the nut 38, allowing the nut 38 to be removed from the insulator 36 or the discharge clamp. In addition, when tightening the nut 38, the air cylinder that is the linear drive source 20 is first contracted, and the robot tightens the nut 38 so that the nut 38, which is engaged in the tool body 12, is screwed into the insulator 36 or the discharge clamp. The arm 14 is operated to extend the linear drive source 20 while driving the fluid motor 28 in the opposite direction. In this way, the tool body 12 tightens the nut 3B to the insulator 36 or the discharge clamp to fix it.
