However, it is not preferable to make a power failure, and the insulator bind 116 holding the overhead electric wire 100 is hooked on the constricted portion of the pin insulator 110, and a large load is applied to the pin insulator 110. Since the pin insulator 110 must be lifted by the length of the shaft portion 112 of the pin, the additional support 130 is attached to the arm metal 102 by removing the shaft portion 112 from the communication hole of the arm metal 102. Work is not easy.

  In addition, in order to attach the support 130 to the brace 102 without causing a power failure, a limited contractor possessing a specific license uses special tools, or attaches protective equipment for preventing a ground fault. It must be done and cannot be dealt with early.

  Moreover, although the armrest attachment apparatus described in Patent Document 1 can be attached without removing the shaft portion of the pin insulator from the communication hole of the armrest, After fitting the shaft portion of the pin insulator into the engagement notch 201, an operation such as passing a bolt through each through hole 202 is required. Therefore, this arm bracket attachment device cannot easily attach the mounting bracket 200 to the arm bracket.

  A first embodiment of a support for an electric wire construction member according to the present invention (hereinafter referred to as “support”) will be described with reference to FIGS. 1 to 6. The same parts as those in the conventional art will be described with the same reference numerals.

  This support is bridged between the shaft portion 112 of the pin lever 110 inserted into the communication hole of the arm metal 102 and the tension lever 140 connected to the tension clamp 120. In the case where the end of the already installed overhead wire 100 is further extended, it can be suitably used.

  That is, as shown in FIG. 1, the support has a rectangular plate-like substrate portion 1 on the tension insulator 140 side and a hook-like portion on the pin insulator 110 side (hereinafter referred to as “first hook-like portion”) 10. Are integrally provided by integral molding or the like. In FIG. 1, the lower surface side of the support member that is directed to the upper surface of the arm metal 102 is drawn upward. Here, the surface drawn on the upper side is referred to as the inner surface, and the surface drawn on the lower side. Is called the outer surface.

  And one short side part of the board | substrate part 1 is inserted | pinched by the groove part of the tip crack of the tension insulator 140, and the connection hole 2 is formed. Since the groove portion of the tension insulator 140 is formed in the vertical direction, one short side portion of the substrate portion 1 is also directed in the vertical direction. Moreover, since the first hook-shaped part 10 is addressed to the upper surface of the arm metal 102, it is directed in the horizontal direction.

  Accordingly, the substrate portion 1 of this support is twisted at the intermediate portion, directed in the vertical direction at one short side portion, and oriented in the horizontal direction at the other short side portion on the bowl-shaped portion side. ing. Furthermore, since the tension insulator 140 is disposed lower than the upper surface of the arm metal 102 so as to face the side surface of the arm metal 102, the support is bent at the center and formed into a square shape when viewed from the front. .

  The first hook-like portion 10 is continuous with the other short side portion of the substrate portion 1 and has a narrower width than the base end portion and protrudes toward the pin insulator 110 (hereinafter referred to as “first pin”). A stick portion) 12, a hook portion 13 (hereinafter referred to as a “first hook portion”) 13 in which the distal end side of the first stick portion 12 is folded back to the substrate portion 1 side, and the first portion. And an opening (hereinafter referred to as “first opening”) 14 provided between the latching portion 13 and the substrate portion 1. Further, the first stick portion 12 has a stop portion 15 (hereinafter referred to as “first stop portion”) protruding from the outer surface at the side edge opposite to the first opening portion 14. .

  And this support is made to pivotally support the hook-like part 20 on the outer surface of the other short side part of the substrate part 1 so as to be swingable. The second bowl-shaped portion 20 includes a base portion 21 that is pivotally supported on the substrate portion 1 by pins or the like, a second stick portion 22 protruding from the base portion 21, and a distal end side of the second stick portion 22. A second hooking portion 23 folded back to the base 21 side and a second opening 24 provided between the second hooking portion 23 and the base 21 are provided. Further, the second stick portion 22 has a second stop portion 25 protruding from the inner surface at the side edge opposite to the second opening 24.

  However, the first hook-shaped portion 10 and the second hook-shaped portion 20 are such that the base portion 21 of the second hook-shaped portion 20 is a substrate so that the first opening portion 14 and the second opening portion 24 face each other. The other short side part of the part 1 is pivotally supported. Therefore, the second hooking portion 23 of the second hook-shaped portion 20 is the first hooking portion 23 in the state where the second hook-shaped portion 20 is turned and overlaps the first hook-shaped portion 10. The first hooking portion 13 of the first hook-shaped portion 10 is hooked to the second hooking portion 25.

  The support tool of the first embodiment is configured as described above, and a method for fixing the support tool to the brace 102 will now be described with reference to FIGS.

  Before fixing the support tool to the arm metal 102, as shown in FIG. 2, a pin insulator 110 is fixed to the arm metal 102, and only one pair of general support tools 130 and 130 are attached to the pin insulator 110. It is supported. The pair of general support tools 130 and 130 are provided between a tension insulator 140 connected to a retention clamp 120 (see FIG. 11) holding the overhead electric wire 100 and a pin insulator 110 fixed to the arm metal 102. It is laid over. Further, the overhead electric wire 100 is erected from one side (left side in the drawing) to the pin insulator 110, and the tip (right side in the drawing) is not erected and is disconnected.

  In order to further extend the overhead electric wire 100 from the tip, the support is attached to the brace 102. Therefore, as shown in FIG. 3, the nut 115 is loosened and the pin insulator 110 is slightly raised by the thickness of the present support tool, and the existing support tool 130 that is addressed to the upper surface of the flange 113 and the arm metal 102 is provided. A space is provided between the two. The nut 115 is not removed from the bolt part 114 of the shaft part 112, and the pin insulator 110 is raised by the amount of being loosened and moving downward.

  And this support tool is brought close to the pin insulator 110 vicinity. In the initial stage of the support, the second hook-shaped portion 20 is separated from the first hook-shaped portion 10 and the first opening 14 and the second opening 24 are opened. .

  Next, as shown in FIG. 4, the first opening portion 14 and the second opening portion 24 of the present support tool are placed so that the shaft portion 112 is sandwiched between the flange portion 113 and the upper surface of the arm metal 102. Move the support.

  Next, as shown in FIG. 5, the second hook-shaped portion 20 is turned to be overlapped with the first hook-shaped portion 10. When the second hooking portion 23 of the second hook-shaped portion 20 hits the first hooking portion 15 and the first hooking portion 13 hits the second hooking portion 25, The second bowl 20 does not turn too much. Therefore, the shaft portion 112 of the pin lever 110 is accurately sandwiched between the first stick portion 12 and the second stick portion 22.

  When the support is pulled away from the arm metal 102 (right side in the drawing), the first hook 13 and the second hook 23 sandwich the shaft 112 of the pin lever 110. . Subsequently, the pin insulator 110 that has been raised is lowered so that the flange 113 is placed on the second flange 20 of the support. At this time, the nut 115 that is still attached to the shaft portion 112 of the pin lever 110 is positioned below the existing support member 130 that is addressed to the lower surface of the arm metal 102, and the nut 115 is disposed between the support member and the nut 115. Are spaced apart.

  Next, as shown in FIG. 6A, another support tool 30 is superimposed on the existing support tool 130 on the lower surface of the arm metal 102. As shown in FIG. 6 (b), the support 30 is formed by twisting and bending a rectangular plate-shaped member 31 at the center, and one end thereof is fitted into the cut portion of the tension insulator 140. The other end is overlapped with the existing support 130 on the lower surface of the arm metal 102. Therefore, this support tool 30 is provided with a connection hole 31a that communicates with the communication hole of the tension insulator 140 at one end and an engagement hole 32 that engages with the shaft 112 of the pin insulator 110 at the other end. It is said that.

  The engaging hole 32 is provided with a reduced diameter portion 32a having an inner diameter that is the same as or slightly larger than the outer diameter of the shaft portion 112 of the pin insulator 110 on the tip edge side, and an enlarged diameter portion 32b having an inner diameter larger than the nut 115 on the center portion side. The shape is different. Therefore, this support tool 30 contracts the shaft portion 112 of the pin lever 110 by pulling the diameter-expanded portion 32b of the engagement hole 32 in a direction away from the arm metal 102 (rightward in the drawing). It can be located in the diameter part 32a.

  Then, by tightening the nut 115, the present support tool, the new support tool 30, and the existing support tools 130 and 130 are fixed to the arm metal 102.

  Then, when one end of the present support tool and the new support tool 30 are fitted into the groove portion of the tension insulator 140 and the cotter pin is inserted into the communication hole and the connection hole, the mounting operation of the support tool is completed. . After that, a new overhead wire 100 is fixed to the retaining clamp 120 attached to the tension insulator 140, and the end of this overhead wire 100 and the tip of the already installed overhead wire 100 are connected. Is finished.

  Even if a force is applied to the support tool from the newly installed overhead electric wire 100 to expand the first latching portion 13 and the second latching portion 23, The first latching portion 13 and the second latching portion 25 are latched by the second latching portion 25 and the second latching portion 23 is latched by the first latching portion 15. The latch part 23 continues to latch the shaft part 112 of the pin insulator 110 without expanding.

  In addition, this invention can be variously changed without being limited to the said embodiment. For example, as shown in FIG. 7, the present support tool is one in which the substrate portion 1 is only twisted at the center portion and is not bent in a hem shape, or the substrate portion 1 is twisted at the center portion as shown in FIG. 8. In addition, a flat plate that is neither bent nor bent can be implemented.

  Further, as shown in FIG. 9, the present support tool is a single-opening opening / closing lever 26 that opens the opening by tilting the second hook-shaped portion 20 toward the first stick portion 12 side like a carabiner. May be pivotally supported on the substrate portion 1.

  Furthermore, as shown in FIG. 10, the present support tool may not be provided with an opening / closing part, and the opening 14 may be left open. However, the support tool of FIG. 10 must be such that the strength of the base plate portion 1 is less likely to be deformed than that provided with the second hook-like portion 20, and therefore the base plate portion 1 and the lock portion 10 are made thicker. It is necessary to use a material with high rigidity.

  Furthermore, although not shown in the figure, even in a support tool provided with an opening / closing lever 26 such as a carabiner or a support tool not provided with an opening / closing lever 26, even if the substrate portion 1 is twisted without bending it into a front view. Alternatively, it may be a flat plate that is neither twisted nor bent.

  Further, the substrate unit 1 and the bowl-shaped unit may be integrated separately. That is, the first screw-shaped portion 10 may be integrated by forming a male screw portion at the base end portion, forming a female screw portion on the substrate portion 1, and screwing both screws together.

  Furthermore, the main object of this support tool is to be able to be fixed to the pin insulator 110 attached to the arm metal 102 later, but in addition, for example, parts can be replaced by rust or the like. You may use it when you have to.
