Description

  The present invention relates to a winding binding suitable for being used for tightly supporting a pin insulator to an overhead electric wire.

  In the electric power company, as shown in FIG. 2 (c), a winding bind 110 is used to tightly support the pin insulator 2 to the overhead electric wire 1.

Here, the winding bind 110 is made of an insulating coated metal wire having a diameter smaller than that of the overhead electric wire 1 and having elasticity and high tension.
Further, as shown in FIG. 2A, the winding bind 110 is formed by bending the semicircular arc part 111 at the center part in the longitudinal direction of the metal wire so that it can be wound around the neck part of the pin insulator 2. At both ends of the semicircular arc portion 111, spiral portions 112a and 112b for winding an electric wire are bent.

When the pin insulator 2 is tightly supported by the live overhead wire 1 using the winding bind 110 configured as described above, the operator can attach the overhead wire 1 attached to the neck of the pin insulator 2 to the overhead wire 1. On the other hand, the semicircular arc 111 of the winding bind 110 is hung on the opposite side of the pin insulator 2 (the front side in FIG. 2 (c)), and the winding grip tongue 120 attached to the tip of the hot stick (FIG. 2 (b)), the spiral portion 112a of the winding bind 110 is inserted into the hole portion 121, and then the winding grip tong 120 is rotated about one turn along the periphery of the overhead electric wire 1 so that the elasticity of the metal wire is obtained. The first spiral portion of the spiral portion 112a (the spiral portion on the semicircular arc portion 111 side) is wound around the overhead electric wire 1 using force.
Thereafter, the worker once removes the spiral portion 112a from the hole portion 121 of the winding grip tongue 120, and then reinserts the spiral portion 112a into the hole portion 121 so that the winding grip tongue 120 is placed around the overhead electric wire 1. By repeating approximately one turn, the overhead wire 1 is wound up to the last spiral portion of the spiral portion 112a.
When the last spiral portion of the spiral portion 112a is wound around the overhead electric wire 1, the worker connects the driver portion 122 of the winding grip tongue 120 to the open end of the overhead wire 1 and the spiral portion 112a (on the side opposite to the semicircular arc portion 111). The spiral portion 112a is fixed to the overhead electric wire 1 by inserting it between the portion and winding the open end of the spiral portion 112a.
Thereafter, the worker winds and fixes the spiral portion 112b of the winding grip 110 around the overhead electric wire 1 in the same procedure.

When removing the winding bind 110 from the overhead wire 1, the operator inserts the driver portion 122 of the winding grip tong 120 between the open end of the spiral portion 112 a of the winding grip 110 and the overhead wire 1. After unscrewing the open end of the spiral portion 112 a from the overhead wire 1, the spiral portion 112 a is inserted into the hole 121 of the wound grip tongue 120, and then the wound grip tongue 120 is placed approximately 1 along the periphery of the overhead wire 1. By rotating around the circumference, the last spiral portion of the spiral portion 112a is removed from the overhead electric wire 1 using the elastic force of the metal wire.
Thereafter, the worker once removes the spiral portion 112a from the hole portion 121 of the winding grip tongue 120, and then reinserts the spiral portion 112a into the hole portion 121 so that the winding grip tongue 120 is placed around the overhead electric wire 1. By repeating approximately one turn, the first spiral portion of the spiral portion 112a is removed from the overhead electric wire 1.
Thereafter, the worker removes the spiral portion 112b of the winding grip 110 from the overhead electric wire 1 in the same procedure.

In addition, in the following Patent Document 1, the present applicant has proposed a winding binding for an annular insulated electric wire that prevents the overhead electric wire from being bitten by forming the open ends of the two spiral portions in an annular shape. .
In addition, in the following Patent Document 2, the applicant of the present invention bent and intersected the central portion in the longitudinal direction of the metal wire in order to make it difficult for the insulator to come off even if the wire is subjected to vibration or impact due to wind or fallen trees. An electric wire winding bind has been proposed in which an annular portion for lever engagement is formed and a spiral portion for winding an electric wire is bent at both ends of a metal wire.

However, in the conventional winding bind 110, when the winding bind 110 is wound and removed from the overhead electric wire 1, the driver portion 122 of the winding grip tongue 120 is connected to the open ends of the spiral portions 112a and 112b of the winding bind 110. If the cover of the overhead electric wire 1 and the winding bind 110 is damaged by the driver portion 122 because it is inserted between the overhead electric wire 1 and twisted or pulled, the true wire of the overhead electric wire 1 and the metal of the winding bind 110 The wire is exposed, and the winding wire 110 is charged by the contact of the exposed true wire of the overhead wire 1 and the exposed metal wire of the winding binding 110, causing a distribution line accident. There was a problem.
In addition, even when working with an insulated jacket instead of the wound grip tongue 120, the overhead wire 1 of the overhead electric wire 1 is gripped from the structure of the wound bind 110 while holding the spiral portions 112 a and 112 b of the wound bind 110 with the insulated jacket. There has been a problem that it is difficult to rotate around one turn along the circumference.

  An object of the present invention is to provide a winding binding that can be wound on and removed from an overhead electric wire without damaging the covering of the overhead electric wire and the winding binding.

The winding binding of the present invention is a winding binding (10) for use in tightly supporting the insulator (2) to the overhead electric wire (1), and has a diameter smaller than the diameter of the overhead electric wire. A semicircular arc portion (11) formed of a coated metal wire and bent at the center in the longitudinal direction of the metal wire so as to be wound around the neck portion of the insulator, and bent at both ends of the semicircular arc portion. First and second spiral portions (12a, 12b) formed, and first and second string-like members attached to the open ends of the first and second spiral portions, respectively. It is characterized by.
Here, the first and second string-like members may be rubber first and second tubes (13a, 13b).
One end portions of the first and second tubes may be inserted into the open end portions of the first and second spiral portions, respectively, and attached with an adhesive.

The winding bind of the present invention has the following effects.
(1) By attaching the first and second string-like members to the open ends of the first and second spiral parts, respectively, the first and the second are used by using an insulating jacket instead of the wound grip tongue. Since the spiral portion can be wound around and removed from the overhead wire, the first and second spiral portions can be wound around and removed from the overhead wire without damaging the sheath of the overhead wire and the winding binding.
(2) By using tubes or strings as the first and second string-like members, the first and second spiral portions can be efficiently wound and removed from the overhead electric wire, and the tubes or strings This makes it possible to prevent disasters such as piercing the eyes because the tip of the winding bind is conspicuous. Further, if several winding bindings are set tightly, the winding bindings are entangled with each other, but can be easily organized by hanging them with a tube or string.

It is a figure which shows the structure of the winding binding 10 by one Example of this invention. It is a figure for demonstrating the structure of the conventional winding binding 110, etc. FIG.

  Said objective was implement | achieved by attaching the 1st and 2nd string-like member to the open end part of the 1st and 2nd spiral part, respectively.

Embodiments of the winding binding according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the winding binding 10 according to one embodiment of the present invention has tubes 13a and 13b attached to open ends (ends opposite to the semicircular arc portion 11) of the spiral portions 12a and 12b, respectively. This is different from the conventional winding binding 110 shown in FIG.

Here, the tubes 13a and 13b are made of rubber, have a strength that does not break even when pulled, and have a length of preferably about 10 cm.
Further, the tubes 13a and 13b are attached by inserting one end portions into the open end portions of the spiral portions 12a and 12b of the winding bind 10, respectively. Therefore, one ends of the tubes 13a and 13b are attached to the open ends of the spiral portions 12a and 12b with an adhesive so that the tubes 13a and 13b do not come out of the spiral portions 12a and 12b even when pulled.

When the pin insulator 2 is tightly supported by the live overhead power wire 1 using the winding bind 10 configured as described above, an operator can attach the overhead wire 1 attached to the neck of the pin insulator 2 to the overhead wire 1. The tube 13a hanging below the overhead wire 1 is hung on the opposite side across the neck of the pin insulator 2 by using the semicircular arc portion 11 of the winding bind 10 and using an insulating jacket attached to the tip of the hot stick. After gripping, the tube 13a is thrown to the opposite side of the overhead wire 1 through the overhead wire 1, and the tube 13a is again gripped by an insulating jacket and pulled downward, thereby utilizing the elastic force of the metal wire. The first spiral portion 12a (the spiral portion on the semicircular arc portion 11 side) is wound around the overhead wire 1.
After that, the worker throws the tube 13a through the upper side of the overhead wire 1 to the opposite side of the overhead wire 1 and then repeatedly holds and pulls the tube 13a with the insulating jacket, thereby repeating the spiral portion 12a. Wind around the overhead wire 1 until the last spiral. When the last spiral portion of the spiral portion 12 a is wound around the overhead electric wire 1, the worker uses an insulating yarn to bind the tube 13 a to the overhead electric wire 1 and fix the spiral portion 12 a to the overhead electric wire 1.
Thereafter, the operator winds the spiral portion 12b of the winding grip 10 around the overhead electric wire 1 in the same procedure, and then binds the tube 13b to the overhead wire 1 to fix the spiral portion 12b to the overhead wire 1.

When removing the winding bind 10 from the overhead wire 1, the operator uses an insulating YT to unscrew the tube 13 a from the overhead wire 1 and passes the tube 13 a over the overhead wire 1 to the opposite side of the overhead wire 1. After throwing it away, the tube 13a is again gripped and pulled downward, and the last spiral portion of the spiral portion 12a is removed from the overhead wire 1 using the elastic force of the metal wire.
After that, the worker uses an insulating jacket to hold the tube 13a hanging below the overhead wire 1 and then throws the tube 13a through the overhead wire 1 to the opposite side of the overhead wire 1 to throw the tube 13a. By repeatedly gripping and pulling downward, the first spiral portion of the spiral portion 12a is removed from the overhead wire 1.
Thereafter, the worker removes the tube 13b from the overhead wire 1 and removes the spiral portion 12b of the winding grip 10 from the overhead wire 1 in the same procedure.

  Thus, the worker can attach and remove the winding bind 10 to and from the overhead electric wire 1 using the insulating Yatco, so that the worker can work without damaging the covering of the overhead electric wire 1 and the winding bind 10. be able to.

  Instead of tying the tubes 13a and 13b to the overhead electric wire 1 and fixing the spiral portions 12a and 12b of the winding bind 10 to the overhead electric wire 1, a weight is attached to the open ends of the tubes 13a and 13b, and an insulating jacket is used. In the same manner as the spiral portions 12a and 12b, the spiral portions 12a and 12b may be fixed to the overhead wire 1 by winding the tubes 13a and 13b around the overhead wire 1 several times and hanging down the weight.
