Description

Detailed Description of the Invention (Industrial Application Field) The present invention applies to cases where a support is connected to an overhead wire via an insulator.
When it becomes necessary to peel off about 5 cm of the polyethylene insulating layer covering the overhead wires, a simple peeler and its convenient device that can easily peel off the covering layer of the electric wires of such elevated overhead wires are provided. It provides:

(Prior art) Conventionally, when trying to peel off the coating layer of electric wires installed at such a high place, it was necessary to manually peel off the coating layer of a strongly adhered polyethylene etc. There was no other way but to peel off the insulating layer, and there was no simple equipment available, which was a great inconvenience.

(Problems to be Solved by the Invention) It is an object of the present invention to provide a simple device that can be easily installed at a high place and whose coating layer can be easily peeled off and removed.

(Means for solving the problem) A fixed base that can be easily inserted into an existing reading terminal on a utility pole is provided, and a rotating tube and electric wire with vertical grooves that can be mutually blocked by mutual rotation are provided. A holding cylinder is mounted on the fixed base, and after inserting the overhead wire into the wire holding cylinder from the side, the vertical groove is closed, and by rotating and sliding the rotating cylinder containing the blade, the wire is set at appropriate intervals at the cutting edge. The adhesive coating of polyethylene or the like on the overhead wire can be easily peeled off and the intended purpose can be easily achieved.

(Embodiment and operation) To explain in detail with reference to the attached drawings which clearly show an example of the implementation of the present invention, 1 is a fixed base with a fixing bracket 3 on which a telephone pole, etc., 2 is to be inserted and fixed. Fix by welding, etc. Reference numeral 4 denotes a rotary tube support hole, which is bored in the upper part of the fixed base 1, and a side hole 6 into which the electric wire 5 can be inserted from the side is bored in communication with the rotary tube support hole 4. Reference numeral 7 denotes a rotary cylinder, which is slidably and rotatably inserted into the rotary cylinder support hole 4 of the fixture in the axial direction. Reference numeral 8 denotes a longitudinal groove formed in the cylinder wall so that the electric wire 5 can be inserted into the side surface of the rotating cylinder from the side. Reference numeral 9 designates a wire holding tube, which is rotatably inserted into the rotary tube 7 from the axial direction. Reference numeral 10 is a vertical groove bored into the cylindrical wall so that the overhead wire can be inserted from the side. 11
When the electric wire holding cylinder 9 is inserted into the rotary cylinder 7 as a bolt, the function is to rotate and fix the two so that the relationship between the two is properly established. If the vertical groove 8 of the rotary tube 7 and the vertical hole 10 of the wire holding tube 9 are also facing upward, both wire holes 8 and 10 are fixed so as to overlap, and the side groove 6 and both boxes are fixed. The electric current vA5 is inserted from above where the grooves 8 and 10 overlap to form an opening.

In this way, when the electric wire 5 is inserted into the electric wire holding tube 9, the two box grooves 8 and 10 are rotated relative to each other so that they do not overlap each other and are staggered so that the rear two tubes 7 , 9 are fixed to each other with the fixing bolts 11, and set in such a state that they can rotate and slide integrally with respect to the fixing base 1. The electric wire 5 is held so that it does not come out into the side groove 6 of the fixed base 1.The base end is fixed with a bolt 13 to one end of the rotary cylinder 7 using a blade mounting bracket 12.
There is a cylindrical hole 14 of the electric wire holding cylinder 9, and a cylindrical hole 15 and a groove 16 that are concentric with the same diameter. Reference numeral 17 denotes a blade, which is attached to the blade mounting bracket with a bolt 18 so that the protrusion of the blade can be adjusted and the size of the blade can be changed. It is adjusted to protrude in an inclined manner to a degree suitable for peeling. A handle 20 is fixed to the other end of the rotary tube 7 with a set screw 21. Reference numeral 22 denotes a stopper which is fixed to the end of the wire holding cylinder with a bolt 23 to support the device so that it remains in a stable position.

When using the present invention with the above configuration, the fixing fitting 3 is passed through the arm of the utility pole where the electric wire 5 is located, fixed with the bolt 24, and the dividing groove 6, double box groove 8, 10, etc. Adjust so that both have overlapping openings, insert the electric wire 5 from the opening side, and attach the electric wire holding cylinder to the rotating cylinder 7 so that the verticals 48 and 10 do not overlap and are mutually non-opening. After adjusting the rotation of 9,
Tighten the fixing bolt 11 to immovably connect both cylinders 7 and 9, and rotate the rotary cylinder 7 and the wire holding cylinder 9 while holding the handle 20 and pressing and sliding it from your left hand to your right hand as shown in Figure 2. By this operation, the cutting edge 19 rotates while moving from left to right on the fixed base, and as a result, the cutting edge 19 rotates while moving from left to right on the fixed table. The coating layer can be easily peeled off.

In carrying out the present invention, the width of the blade can be set to a desired peeling interval, and the peeling can be performed by only rotating the rotary cylinder without sliding it in the axial direction. This type of format is disclosed. Furthermore, in carrying out the present invention, the rotary cylinder is not made to slide on the fixed base, but a spiral that should be interlocked between the rotary cylinder support hole and the outer surface of the rotary cylinder is cut so that it moves in the axial direction at the same time as rotation. It is also possible to do so, and it can be implemented arbitrarily.

(Effects of the Invention) The present invention has the structure and operation as detailed above, and provides a coating that is difficult to peel off when an electric wire is to be supported via an insulator on an overhead line at a high place. The insulating coating layer, such as polyethylene, is easily peeled off using the blade 17 by sliding and rotating the device at a sliding interval of about 5 cm, exposing the wire at the required distance of about 5 cm. It is possible to easily support electric wires through the insulator, and is extremely useful and effective in this type of operation.
