Description

The present disclosure relates to an auxiliary tool for electric wire retention that assists the work of winding a flexible linear body for electric wire retention around an insulator.

Conventionally, an electric wire is fastened to an insulator attached to an arm of a utility pole via a bolt or the like using a retaining tool as described in Patent Document 1, for example, and the electric wire is in a state where a desired tension is applied between the electric poles. It is considered to be erected. In the retaining tool described in Patent Document 1, a spiral strand bundle is connected to both ends of a U-shaped retaining loop. Therefore, if two strand bundles are entwined around the outer periphery of the conductor portion from which the coating of the electric wire is stripped and the conductor portion is held inside the entwined strand bundle, the electric wire can be retained by the retaining tool. If the retaining loop is wound around the small diameter portion of the insulator and the wire is held by a bundle of wires while tension is applied to the wire, the wire can be fastened to the insulator.

Japanese Patent No. 3051491

However, when the retaining loop comes into contact with a metal fitting or the like that supports the insulator, electric leakage may occur from the metal fitting. For this reason, the work of winding the retaining loop around the small diameter portion of the insulator should be performed so that the retaining loop does not come off the small diameter portion of the insulator and come into contact with the metal fittings, etc., and that the retaining loop is not removed from the small diameter portion of the insulator. You need to be careful.

One aspect of the present disclosure is to provide an electric wire retaining assisting tool capable of further improving the workability of the work of winding a flexible linear body such as a retaining loop around a small diameter portion of an insulator.

The electric wire retaining assisting tool as one aspect of the present disclosure includes a pair of large-diameter portions and a small-diameter portion that is provided between the pair of large-diameter portions and has a smaller diameter than any of the pair of large-diameter portions. The small diameter portion can be used for an insulator configured so that a flexible linear body for retaining an electric wire can be wound around the insulator. Further, the electric wire retaining assisting tool includes at least one engaging portion, an opening portion, at least one support portion, and at least one guide portion.

The engaging portion is configured so that the inner peripheral surface can be engaged with the small diameter portion. The opening is formed in a part of the engaging portion, and by communicating the outer periphery of the engaging portion with the inner peripheral surface, the position where the opening is engaged with the inner peripheral surface from the outer peripheral side of the engaging portion. The small diameter portion can be inserted up to. The support portion is configured to support the linear body in a state of being wound around the inner peripheral surface of the engaging portion. The guide portion is configured to guide the engaging portion, which moves closer to the insulator, to a position where the inner peripheral surface engages with the small diameter portion.

According to such a configuration, by inserting the small diameter portion of the insulator through the opening, the small diameter portion can be engaged with the inner peripheral surface of the engaging portion. When the small diameter portion is inserted through the opening in this way, the operator can support the linear body in a state of being wound along the inner peripheral surface of the engaging portion via the support portion. By doing so, when the small-diameter portion of the insulator engages with the inner peripheral surface of the engaging portion, the linear body is in the same state as wrapped around the small-diameter portion of the insulator. Further, when the operator moves the engaging portion from the radial outside of the small diameter portion so as to be close to the insulator in order to insert the small diameter portion from the opening, the guide portion is inside the engaging portion. The moving engaging portion is guided to a position where the peripheral surface engages with the small diameter portion.

Therefore, the operator can engage the inner peripheral surface of the engaging portion with the small diameter portion of the insulator by guiding the engaging portion by the guide portion without moving the engaging portion so accurately. Can be done. Then, when the small-diameter portion of the insulator engages with the inner peripheral surface of the engaging portion, the linear body is in the same state as wrapped around the small-diameter portion of the insulator, as described above. Therefore, it may be possible to further improve the workability of the work of winding the flexible linear body around the small diameter portion of the insulator.

In the electric wire retaining assisting tool of the present disclosure, the guide portion is provided at the end portion of the engaging portion on the opening side, and slides in contact with at least one of the large diameter portions of the insulator. , The slope may be provided so as to guide the opening toward the small diameter portion of the insulator. In such a configuration, when the engaging portion is moved so as to be close to the insulator, when the slope abuts on the large diameter portion of the insulator, the stress applied to the slope due to the abutment becomes a component force along the slope. Correspondingly, the slope slides with respect to the large diameter portion, so that the guide portion guides the opening toward the small diameter portion of the insulator. Therefore, the engaging portion can be satisfactorily guided to a position where the inner peripheral surface of the engaging portion engages with the small diameter portion. Therefore, it may be possible to further improve the workability of the work of winding the flexible linear body around the small diameter portion of the insulator.

Further, in the electric wire retaining assisting tool of the present disclosure, the guide portion has a predetermined direction in which the inner peripheral surface of the engaging portion is parallel to the axial direction of the insulator when the inner peripheral surface is engaged with the small diameter portion. As a result, the opening is provided by projecting from the engaging portion in the predetermined direction and preventing the engaging portion from approaching the metal fitting when it comes into contact with the metal fitting that supports the insulator via a bolt. The portion may be configured to prevent the portion from being displaced from the position facing the small diameter portion. In such a configuration, when the engaging portion is moved so as to be close to the insulator, the engaging portion is tilted and the guide portion provided so as to project in the predetermined direction comes into contact with the metal fitting. The guide portion suppresses the opening from being displaced from the position facing the small diameter portion by suppressing the engaging portion from being close to the metal fitting. Therefore, the engaging portion can be satisfactorily guided to a position where the inner peripheral surface of the engaging portion engages with the small diameter portion. Therefore, it may be possible to further improve the workability of the work of winding the flexible linear body around the small diameter portion of the insulator.

Further, in that case, the guide portion provided so as to project in the predetermined direction is configured to engage with at least one of the large diameter portions of the insulator when the inner peripheral surface engages with the small diameter portion. May be done. In such a configuration, when the inner peripheral surface of the engaging portion engages with the small diameter portion of the insulator, the guide portion provided so as to project in the predetermined direction engages with at least one large diameter portion of the insulator. Therefore, the state in which the inner peripheral surface of the engaging portion is engaged with the small diameter portion of the insulator can be maintained more stably. Therefore, the state in which the flexible linear body is wrapped around the small diameter portion of the insulator can be maintained more stably.

Further, in the electric wire retaining assisting tool of the present disclosure, the support portion includes at least one inner peripheral support portion configured to support the linear body from the inner peripheral side of the engaging portion, and the linear shape. It may be provided with at least one outer peripheral support portion configured to support the body from the outer peripheral side of the engaging portion. In such a configuration, the linear body is supported from both the inner peripheral side and the outer peripheral side of the engaging portion by the inner peripheral support portion and the outer peripheral support portion. Therefore, the linear body is better supported in a state of being wound along the inner peripheral surface of the engaging portion. Therefore, as described above, during the work of engaging the small diameter portion of the insulator with the inner peripheral surface of the engaging portion while the linear body is supported along the inner peripheral surface of the engaging portion via the supporting portion. , It is possible to prevent the linear body from coming off the engaging portion. Therefore, the workability of the work can be further improved. Further, even after the small-diameter portion of the insulator is engaged with the inner peripheral surface of the engaging portion, it is possible to further better suppress the linear body from being disengaged from the engaging portion by the support portion. Therefore, the linear body can be better maintained in a state of being wrapped around the small diameter portion of the insulator.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
[1. Embodiment]
[1-1. Constitution]
As shown in FIGS. 1 and 2, the electric wire retaining auxiliary tool (hereinafter referred to as the auxiliary tool) 1 of the embodiment includes an engaging portion 3, an engaging portion 5, two first guide portions 7, and two. A second guide portion 9, two first support portions 11, a second support portion 13, two third support portions 15, a third guide portion 17, and a fourth guide portion 19 are provided. It is integrally molded with black resin.

Both the engaging portion 3 and the engaging portion 5 are configured in a horseshoe-shaped plate shape, and are arranged in parallel by the spacing in the plate thickness direction being defined by the support portions 11 to 15. In the following description, the right-handed Cartesian coordinates in which the direction from the engaging portion 5 to the engaging portion 3 in the plate thickness direction is the + Z direction and the direction in which the horseshoe shape is opened is the + X direction are used for each part. It may indicate a positional relationship. However, such coordinates are set for convenience to explain the positional relationship of each part, and are irrelevant to the posture and positional relationship when actually used. For example, the auxiliary tool 1 may be used with the + Z direction facing up, may be used with the + Y direction facing up, or may be used in other postures.

The distance between the two ends 3A and 3A of the engaging portion 3 is formed to be slightly smaller than the diameter (that is, the inner diameter) of the inner peripheral surface 3B of the engaging portion 3. Similarly, the distance between the two ends 5A and 5A of the engaging portion 5 is formed to be slightly smaller than the diameter of the inner peripheral surface 5B of the engaging portion 5. Further, the inner diameters of the inner peripheral surface 3B of the engaging portion 3 and the inner peripheral surface 5B of the engaging portion 5 are set so as to be in close contact with the small diameter portion 85A of the retaining insulator 85 shown in FIG. ing. Therefore, when the small diameter portion 85A of the retaining insulator 85 is inserted from the opening 20 whose four corners are defined by the ends 3A, 3A of the engaging portion 3 and the ends 5A, 5A of the engaging portion 5, the small diameter portion 85A is inserted. After elastically deforming the engaging portions 3 and 5 to enter, engages with the inner peripheral surfaces 3B and 5B. By this engagement, the auxiliary tool 1 is connected to the retaining insulator 85 at least to the extent that it does not fall from the retaining insulator 85 by its own weight.

Further, a first guide portion 7 protruding in the + Z direction is formed at each of the end portions 3A and 3A of the engaging portion 3. The + X side end surface of each first guide portion 7 constitutes a slope 7A inclined so as to go toward the + X side toward the + Z direction from the end portion 3A. Further, a second guide portion 9 protruding in the −Z direction is formed at each of the end portions 5A and 5A of the engaging portion 5. The + X-side end surface of each of the second guide portions 9 constitutes a slope 9A inclined so as to go toward the + X side from the end portion 5A in the −Z direction. That is, the slopes 7A and 9A have a shape that opens to the + X side with the opening 20 interposed therebetween as a whole.

Therefore, when the slope 7A or 9A abuts on the two large-diameter portions 85B (specifically, the axially outer surface of the retaining porcelain 85 in the large-diameter portion 85B) of the retaining porcelain 85, the abutment causes the slopes 7A or 9A. The slope 7A or 9A slides with respect to the large diameter portion 85B depending on the component force along the slope 7A or 9A of the applied stress. As a result, the opening 20 is guided toward the position of the retaining insulator 85 facing the small diameter portion 85A. Therefore, when the operator presses the opening 20 against the small diameter portion 85A of the retaining insulator 85 in an attempt to engage the engaging portions 3 and 5 with the small diameter portion 85A, the position of the auxiliary tool 1 is slightly displaced in the ± Z direction. Even if it is, the engaging portions 3 and 5 can be satisfactorily engaged with the small diameter portion 85A by the action of the slope 7A and the slope 9A.

Further, between the two sets of end portions 3A and 5A arranged so as to overlap in the ± Z direction, a first support portion 11 (an example of an inner peripheral support portion) curved convexly in the center direction of the opening portion 20 respectively. It is connected. The −X side end portion on the inner peripheral surface 3B of the engaging portion 3 and the −X side end portion on the inner peripheral surface 5B of the engaging portion 5 are second support portions 13 (convexly curved in the opening 20 direction). It is connected via an example of an inner peripheral support portion). Further, at a position on the −X side of each end portion 3A of the engaging portion 3, the outer circumference of the portion where the −X side end portion of the first guide portion 7 is arranged and each end of the engaging portion 5. At a position on the −X side of the portion 5A, a straight line is provided between the second guide portion 9 and the outer periphery of the portion where the −X side end portion is arranged by the third support portion 15 (an example of the outer peripheral support portion). It is connected in a shape. Therefore, the support portions 11 to 15 can support the linear body 87 as shown in FIG. 4 along the inner peripheral surfaces 3B and 5B of the engagement portions 3 and 5.

As shown in FIG. 4, the linear body 87 has a retention loop 87B which is formed in a U shape by a twisted wire bundle and whose surface is coated with a resin, and a spiral shape which is connected to both ends of the retention loop 87B. The wire bundles 87A and 87A are provided. If the retaining loop 87B of such a linear body 87 is wound so as to pass through the outside of the first support portion 11 and the second support portion 13 and the inside of the third support portion 15, the retention loop 87B is formed. Can be supported along the inner peripheral surfaces 3B, 5B of the engaging portions 3, 5.

Moreover, flexible flakes 11A that engage with the outer periphery of the retaining loop 87B are formed so as to project on the + Z side inner peripheral surface and the −Z side inner peripheral surface of the first support portion 11. Further, a flexible thin piece 15A that engages with the outer periphery of the retaining loop 87B is also formed so as to project in the vicinity of the third support portion 15 on the surfaces of the engaging portions 3 and 5 facing each other. Therefore, supporting the retention loop 87B along the inner peripheral surfaces 3B and 5B can be performed more stably.

As shown in FIG. 5, for example, the retaining insulator 85 may be attached via a bolt 83 between a pair of long flat metal fittings 80, 80 attached to an arm metal (not shown). In that case, the linear body 87 to which the auxiliary tool 1 is attached is inserted from the long side of the metal fittings 80, 80 so as to sandwich the retaining insulator 85 between the wire bundles 87A, 87A. Then, when the operator pulls the two strand bundles 87A and 87A toward himself, the auxiliary tool 1 is guided by the slopes 7A and 9A as described above, and the engaging portions 3 and 5 engage with the retaining insulator 85. do. After that, by peeling off the coating 81B of the electric wire 81 and winding the wire bundles 87A and 87A around the exposed portion of the core wire 81A with the desired tension applied to the electric wire 81, the electric wire 81 is placed between the utility poles with the desired tension. Can be erected.

Further, the auxiliary tool 1 includes the following third guide portion 17 and fourth guide portion 19 (both are examples of guide portions provided so as to project in a predetermined direction). The third guide portion is configured to have an L-shaped cross section that protrudes in the + Z direction from the −X side end portion of the engaging portion 3 and then bends in the + X direction. The fourth guide portion is configured to have an L-shaped cross section that protrudes in the −Z direction from the −X side end portion of the engaging portion 5 and then bends in the + X direction.

As illustrated in FIG. 6, in the fourth guide portion 19, when the auxiliary tool 1 is tilted and the fourth guide portion 19 comes into contact with the metal fitting 80 on the −Z side, the engaging portions 3 and 5 come into −Z. By suppressing the proximity to the metal fitting 80 on the side, the opening 20 is suppressed from being displaced from the position facing the small diameter portion 85A. Similarly, when the third guide portion 17 comes into contact with the metal fitting 80 on the + Z side due to the auxiliary tool 1 being tilted or the like, the engaging portions 3 and 5 come close to the metal fitting 80 on the + Z side. By suppressing the above, the opening 20 is suppressed from being displaced from the position facing the small diameter portion 85A.

Further, since the third guide portion 17 and the fourth guide portion 19 are configured to have an L-shaped cross section as described above, the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5 are small diameter portions of the retaining insulator 85. When engaged with 85A, it engages with the large diameter portion 85B of the retaining insulator 85 from the outer peripheral side. Further, the third guide portion 17 and the fourth guide portion 19 are sufficiently spaced from the first guide portions 7, 7 and the second guide portions 9, 9 (for example, 45 ° or more around the axis of the retaining insulator 85). It is open and provided. Therefore, even after the auxiliary tool 1 is attached to the retaining insulator 85 attached to the utility pole, the color of the retaining insulator 85 can be visually confirmed from the ground.

[1-2. effect]
According to the embodiment described in detail above, the following effects are obtained.
(1A) By inserting the small diameter portion 85A of the retaining insulator 85 from the opening 20 of the auxiliary tool 1, the small diameter portion 85A can be engaged with the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5. When the small diameter portion 85A is inserted from the opening 20 in this way, the operator supports the retaining loop 87B in a state of being wound along the inner peripheral surfaces 3B and 5B via the support portions 11 to 15. be able to. By doing so, when the small diameter portion 85A of the retaining insulator 85 is engaged with the inner peripheral surfaces 3B, 5B of the engaging portions 3, 5, the retaining loop 87B is in the same state as that wound around the small diameter portion 85A of the retaining insulator 85. Will be. Moreover, in the present embodiment, since the first support portion 11 and the second support portion 13 are curved convexly toward the center of the retaining insulator 85, the retention loop 87B is in a state extremely close to that directly wound around the small diameter portion 85A. Supported by.

Further, in order to insert the small diameter portion 85A from the opening 20 in this way, when the operator moves the auxiliary tool 1 from the radial outside of the small diameter portion 85A so as to be close to the retaining insulator 85, the auxiliary tool 1 The guide portions 7, 9, 17, and 19 provided in the above guide the engaging portions 3, 5 to the positions where the inner peripheral surfaces 3B, 5B engage with the small diameter portion 85A.

Therefore, the operator can guide the engaging portions 3 and 5 by the guide portions 7, 9, 17, and 19 to guide the inner peripheral surfaces 3B and 5B without moving the auxiliary tool 1 so accurately. It can be engaged with the small diameter portion 85A. Therefore, the workability of the work of winding the retaining loop 87B around the small diameter portion 85A may be further improved.

(B) Further, in the first guide portion 7 and the second guide portion 9, the slope 7A or 9A is brought into contact with the large diameter portion 85B of the retaining insulator 85, so that the opening 20 is brought into contact with the small diameter portion 85A of the retaining insulator 85. Guide toward the opposite position. Therefore, the engaging portions 3 and 5 can be satisfactorily guided to the positions where the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5 engage with the small diameter portion 85A. Therefore, the workability of the work of winding the retaining loop 87B around the small diameter portion 85A of the retaining insulator 85 may be further improved.

(C) Further, in the third guide portion 17 and the fourth guide portion 19, when the auxiliary tool 1 is tilted and the third guide portion 17 or the fourth guide portion 19 comes into contact with the metal fitting 80, the engaging portion 3 , 5 is prevented from being closer to the metal fitting 80. Therefore, it is suppressed that the opening 20 is displaced from the position facing the small diameter portion 85A, and the engaging portions are moved to the positions where the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5 engage with the small diameter portion 85A. It is possible to guide 3 and 5 well. Therefore, the workability of the work of winding the retaining loop 87B around the small diameter portion 85A of the retaining insulator 85 may be further improved.

(D) Further, in the third guide portion 17 and the fourth guide portion 19, when the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5 engage with the small diameter portion 85A of the retaining insulator 85, the large diameter portion 85A of the retaining insulator 85 is engaged. Engage with the insulator 85B from the outer peripheral side. Therefore, the state in which the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5 are engaged with the small diameter portion 85A of the retaining insulator 85 can be maintained more stably. Therefore, the state in which the retaining loop 87B is wound around the small diameter portion 85A of the retaining insulator 85 can be maintained more stably.

(E) The first support portion 11 and the second support portion 13 support the retention loop 87B from the inside of the engagement portions 3 and 5, and the third support portion 15 supports the retention loop 87B from the outside of the engagement portions 3 and 5. Support from. Therefore, the retaining loop 87B is better supported in a state of being wound along the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5. Therefore, while the retaining loop 87B is supported along the inner peripheral surfaces 3B and 5B, the retaining loop 87B engages with the retaining loop 87B during the work of engaging the small diameter portion 85A of the retaining insulator 85 with the inner peripheral surfaces 3B and 5B. It is possible to suppress deviation from 3 and 5. Therefore, the workability of the work can be further improved.

Further, even after the small diameter portion 85A of the retaining insulator 85 is engaged with the inner peripheral surfaces 3B and 5B of the engaging portions 3 and 5, the retaining loop 87B is further suppressed from being disengaged from the engaging portions 3 and 5. be able to. Therefore, the retaining loop 87B can be better maintained in a state of being wound around the small diameter portion 85A of the retaining insulator 85.

(F) Further, since the slopes 7A and 9A have a shape that opens in both ± Z directions on the side to be inserted into the insulator 85, the retaining loops 87B having various thicknesses such as 4 mm, 5 mm, and 60 mm ² are good. Can be wrapped around the retaining insulator 85.

(G) Further, from between the third guide unit 17 and the fourth guide unit 19 and the first guide units 7, 7 and the second guide units 9, 9, an auxiliary tool is attached to the retaining insulator 85 attached to the utility pole. Even after 1 is attached, the color of the retaining insulator 85 can be visually confirmed from the ground. Therefore, the work of confirming the type of the retaining insulator 85 from the ground becomes easy.
