Description

  The present invention relates to an insulating sheet fixing tool, and in particular, in an overhead distribution line, when performing various operations by an indirect hot wire method, an insulating sheet to be installed so as to cover an insulating object such as a utility pole or a brace is insulated. The present invention relates to a fixing device for an insulation armor effective for fixing an object in a covered state.

  Conventionally, when various work is performed on overhead distribution lines using the indirect hot wire method, it is possible to prevent accidental accidents such as ground faults, short circuits, electric shocks, etc., due to accidental contact between the edge lines and workers. In order to do so, an insulation sheet is attached so as to cover insulation objects such as utility poles, armatures, and distribution lines, and the insulation sheet is fixed in a state of covering the insulation object with a fixing tool such as a fixing clip. .

  An example of this type of fixture is described in Patent Document 1. The fixture includes a pair of curved handles that are connected so as to be openable and closable, a spring member that constantly urges both handles in a closing direction, a roller that is rotatably provided at a point of both handles, and one handle. And a grip portion provided at the end of the.

  The fixture having such a configuration grips the grip portion using an indirect hot wire tool such as an insulating yat, and operates the indirect hot wire tool so that both handles are connected to the side of the insulation object (distribution line) from the side of the distribution line. In the direction, the distance between the tips of both handles is pressed against the distribution line with the insulating sheet attached, and the distance between the ends of the handles is pushed wide to push the distribution line together with the insulation sheet between the central portions of the handles. Thereby, it can attach in the state which pinched | interposed the insulating sheet on the outer side of the insulating sheet, and can fix the insulating sheet in the state which covered the distribution line.

  By the way, in the fixture having the above-described configuration, two operations, that is, an operation of attaching the insulation sheet so as to cover the distribution line and an operation of attaching the fixture to the outside of the insulation sheet are required. It takes time and effort to attach and fix the distribution line with the distribution line covered.

  Moreover, since only the grip part provided in the edge part of one handle | steering_wheel is gripped with indirect hot-wire tools, such as an insulating Yatco, equal force cannot be applied to both handles with an indirect hot-wire tool. For this reason, when a distribution line with an insulating sheet attached is pressed between the tips of both handles, a rotating force is generated in the direction of the handle that is in a cantilevered state and has a small pushing force. May come off the grip. For this reason, an operation such as re-gripping the grip portion with an indirect hot wire tool is required, and the operation of attaching the fixture to the outside of the insulating sheet is very laborious.

  In addition, when the distribution line is pushed together with the insulation sheet between both handles of the fixture, the frictional force between each handle and the insulation sheet is reduced by the rotation of the roller, but an equal force is applied to both handles. Therefore, there is a large difference in the frictional force between the roller of each handle and the insulating sheet, and the part of the insulating sheet corresponding to the roller with the larger frictional force may be worn or damaged. .

In addition, since the pushing force applied to both arms 2 and 5 is uneven, the arm is in a cantilever state, and a rotational force in the direction of the arms 2 and 5 having a small pushing force acts, so that the grip portion 11 is indirectly hot. The fixing tool 1 can be easily attached to the utility pole 35 in a short time without being detached from the tool.

  Further, since the electric pole 35 and the arm metal 3637 are covered with the insulating sheet 25 after the fixture 1 is attached to the electric pole 35, the frictional force with the roller 17 of the guide member 16 of each arm 2, 5 of the fixture 1. Therefore, the insulating sheet 25 is not partially worn or damaged.

  Further, by operating an indirect hot wire tool from the front side of the utility pole 35, the fixture 1 can be attached to the utility pole 35, and the insulating sheet 35 attached to the fixture 1 is attached to the utility pole 35 by the main seat portion 26. The front side portion and both side surface portions are covered, the sub sheet portions 28 and 29 cover the periphery of the arm brackets 36 and 37, and the auxiliary sheet portions 30 and 31 are connected to the utility pole 35 and the arm brackets 36 and 37, respectively. Since it can be attached so as to cover the upper surface side of the boundary portion, it is possible to efficiently perform the operation of covering the utility pole 35 and the arm brackets 36 and 37.

  In the present embodiment, the insulating sheet 25 is attached to the outer surface side of both arms 2 and 5 of the fixture 1 by the surface fastener 20. However, as shown in FIG. After being wound around, the fixing tool 1 may be attached to the outside of the insulating sheet 40, and the insulating sheet 40 may be fixed to the utility pole 35 with the fixing tool 1. Also in this case, the indirect hot-line tool can apply an equal pushing force to both arms 2 and 5 of the fixture 1, so that the pushing force to both arms 2 and 5 is not uniform. There is no difference in the frictional force between the roller 17 of the guide members 16 and the insulating sheet 40 and the frictional force with the roller 17 of the guide member 16 causes wear or damage to the insulating sheet 40. There is no such thing.
