Description

  The present invention relates to a laying cable support, and in particular, relates to an apparatus that communicates between end portions of a spiral hanger installed on a messenger wire so that a line tool can be inserted without human intervention.

  Conventionally, when laying a cable such as a communication line between utility poles, first install a strong messenger wire, and then attach a spiral hanger formed around the wire to the messenger wire. It has been performed to support a messenger wire via a spiral hanger by placing the cable in a spiral hanger in an external state (see, for example, Patent Document 1).

  Here, when the laying cable is supported in the spiral hanger, the laying cable connected to the rear end portion is pulled in by inserting a passing tool from the leading end side into the guide space of the spiral hanger. Can be supported.

  Since this spiral hanger is externally attached to a messenger wire installed between utility poles, it is in a state of extending in a linear direction. For this reason, for example, when laying a cable laid on a utility pole located at a corner, even if the ends of the spiral hangers are connected to each other, the tip of the line tool is located between the guide spaces of the spiral hangers. It escapes from the gap.

  For this reason, at locations close to the utility poles at the corners, by securing the work space by separating the ends of the spiral hangers, the worker who climbed the high place with an aerial work vehicle etc. It is necessary to carry out an operation of drawing out the line tool from the end of the spiral hanger and inserting it into the end of the spiral hanger on the downstream side.

In order to facilitate the work at this corner, a corner guide device is installed on the power pole at that corner, so that the end of the spiral hanger on the upstream side and the end of the spiral hanger on the downstream side are installed. Has also been proposed to provide a guide space for the line tool (for example, see Patent Document 2).

  However, in such a conventional corner guide device, since it is an expensive and heavy structure with guide rails and guide rollers installed on the base, it cannot be left attached to the utility pole, and the laying cable It is necessary to prepare an aerial work vehicle and attach and detach the base to the utility pole every time the work is installed between the utility poles.

  Also, in recent years, the messenger wires are installed in a state where they intersect with the space above the road intersection, and the cables are refracted by passing the cables through the spiral hangers that extend in the extended direction. It is also being built in.

  Also in this case, every time the work for laying the laying cable is carried out, the tool is pulled out from the end of the spiral hanger on the upstream side by riding on an aerial work vehicle prepared with the intersection closed, and the downstream side. It is necessary to perform the work of inserting into the end of the spiral hanger. In this case, since the messenger wires only cross at the intersection of the road, it is not possible to use a heavy corner guide device as described in Document 2 above.

  As a result, the work of laying the cable laid at the refracted part is too expensive, and it is necessary to stop the road when it is refracted at the intersection. Also, it cannot be done quickly.

  Therefore, the present invention facilitates the construction work of the laying cable at the refraction point and reduces the cost by realizing a simple structure in which the ends of the spiral hanger are connected to each other directly on the messenger wire. It is an object of the present invention to provide a laying cable support that can be converted into a cable.

It is characterized by this.

  In this invention, the both ends of the guide member can be attached in parallel to the spiral hanger installed on the messenger wire simply by fixing the both ends of the guide member to the messenger wire, and the opening directions of the respective guide spaces coincide with each other. Thus, a communication path can be formed. For this reason, the passing tool inserted through the spiral hanger on the upstream side can enter the guide member and be directly delivered to the spiral hanger on the downstream side. Therefore, it is possible to use the cable every time the laying cable is installed with the light and inexpensive guide member having a simple structure only including the mounting member installed.

  A second invention of a laying cable support that solves the above-described problems is characterized in that, in addition to the specific matter of the first invention, the guide member is made of a bendable material.

  In the present invention, the guide member can be bent so that the opening directions of both end portions coincide with each other according to the opening directions of the end portions of the upstream spiral hanger and the downstream spiral hanger. Therefore, the guide member can be bent and attached to the messenger wire within a certain range without preparing a wide variety of guide members having different degrees of bending.

  In addition to the specific matter of the second invention, the third invention of the laying cable support that solves the above-mentioned problem is that the guide member is formed in a shape in which the extension lines in the opening direction at both ends at no load intersect. It is characterized by being.

  In this invention, the opening direction of the both end portions is changed by making the guide member linear or further bent according to the opening direction of the end portions of the upstream spiral hanger and the downstream spiral hanger. It is possible to make them coincide with each other, and it is possible to widen the range in which the angle at which the opening direction of the end of the spiral hanger intersects can be handled. Therefore, it is possible to avoid attaching the guide member with an excessive load applied thereto, and the guide member can be easily attached to the messenger wire.

  A fourth invention of a laying cable support that solves the above problem is characterized in that, in addition to the specific matters of any of the first to third inventions, the guide member is formed in a bellows shape. Is.

  In the present invention, the bellows-shaped guide member can be easily bent so that the opening directions of both ends coincide with each other in accordance with the opening directions of the ends of the upstream spiral hanger and the downstream spiral hanger. Therefore, the guide member can be easily bent and attached to the messenger wire without preparing a wide variety of guide members having different degrees of bending.

  In addition to the specific matters of any of the first to third inventions, the fifth invention of the laying cable support that solves the above problems is characterized in that the guide member is made of a spiral peripheral circuit material, It is characterized in that the gap between the peripheral line materials is clogged to such an extent that the tip of the wiring tool does not enter.

  In this invention, the guide member of the spiral circumferential line material can be easily bent and attached to the messenger wire, and the tip of the wiring tool does not enter between the circumferential line materials and is guided while sliding on the adjacent circumferential line material. Guided through the space. Therefore, the guide member (circumferential line material) can be easily bent and attached to the messenger wire without preparing a wide variety of guide members having different degrees of bending.

By simply doing this, the end of the spiral hanger and both ends of the guide member can be made parallel to each other to smoothly communicate with each other, and the tip of the wire tool can be smoothly guided into the guide space. It can be passed through.

  Therefore, it is possible to leave this guide member attached to the messenger wire. For example, even when installing a cable refracted in a space above the intersection of the road, the road is blocked and work at high places The installation work of the laying cable can be performed easily and at low cost simply by installing the guide member without using a car, and can be used every time the laying cable is installed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-6 is a figure explaining 1st Embodiment of the laying cable support tool based on this invention.

  First, a cable laid using this embodiment will be described. In FIG. 1, the laying cable C is, for example, a communication cable such as an optical fiber or a conductive wire laid between power poles. Such a laying cable C has a strength sufficient to be laid and supported directly between the power poles. Therefore, the messenger wire W having a desired strength is installed between the utility poles, and the spiral hanger H around which the peripheral line material h is circulated is sheathed. Generally, the laying cable C is inserted into the hanger H to support the laying cable C on the messenger wire W via the spiral hanger H.

  This laying cable C is guided into the guide space Sh by guiding and passing the wire tool 100 shown in FIG. 2 into the guide space Sh defined by the peripheral line material h of the spiral hanger H. Pull it in and support it on the spiral hanger H.

  As shown in FIG. 2, the wiring tool 100 used here includes a center rod 101 formed longer than a plurality of circumferential pitches ph of the circumferential line material h constituting the spiral hanger H, and the center rod. A plurality of sliding rods 102 which are formed longer than 101 and fixed to both ends thereof to be curved and attached, and the tip of the center rod 101 is formed with a sharpened tip side. A tool tip 103 attached to the tip, a weight 104 designed to be heavier than the tool tip 103 and attached to the rear end of the center rod 101, and set longer than the spiral hanger H A lead wire 105 having a strength capable of being pushed out without being refracted when the wire tool 100 body is inserted into the spiral hanger H; It is equipped with a.

  As a result, the wire passing tool 100 inserts the tool tip 103 into the guide space Sh of the spiral hanger H from one end side and feeds the lead wire 105, thereby forming the peripheral line material h that defines the inner surface of the guide space Sh. The sliding rod 102 can be inserted through sliding contact. At this time, the wire tool 100 maintains the curved shape of the slide rod 102 and the posture in which the weight 104 is lowered on the rear end side, so that the tool tip 103 on the tip side floats in the guide space Sh. The tool tip 103 can be advanced to the other end side of the guide space Sh without escaping from between the peripheral line members h of the spiral hanger H. For this reason, the wiring tool 100 temporarily connects the laying cable C to the rear end of the lead wire 105, grabs it from the other end side of the guide space Sh of the spiral hanger H, and pulls out the laying cable C. The spiral hanger H can be drawn into and inserted into the guide space Sh, and the laying cable C can be supported by the messenger wire W via the spiral hanger H.

  From this, as shown in FIG. 3, for example, when the wiring tool 100 needs to lay the cable C on the utility pole D installed at the corner of the road, the utility pole D at the corner. After climbing up and using the gap between the ends of the spiral hanger H and pulling it out of the guide space Sh of the spiral hanger H on the upstream side, the guide space Sh of the spiral hanger H on the downstream side By inserting and inserting the tool tip 103, the laying cable C can be installed even in such a refracting path.

  Similarly, as shown in FIG. 4, for example, when it is necessary to lay the laying cable C in a space on a road intersection, the line tool 100 is used for an aerial work vehicle after blocking the road. The tool tip 103 is inserted through the guide space Sh of the spiral hanger H from the upstream side to the downstream side by using the gap between the ends of the spiral hanger H, and on the intersection. The laying cable C can be laid on a path that is refracted in space.

  However, when only the spiral hanger H is installed in this way, when the laying cable C is installed at the refraction point, the spiral hanger H is climbed on the utility pole D or on the aerial work vehicle after traffic regulation. It is necessary to perform the operation of inserting and passing the line tool 100 through the guide space Sh, and the line tool 100 cannot be inserted and passed continuously like the spiral hanger H that is linearly continuous. . In particular, when it is necessary to refract the laying cable C in the space above the intersection, permission of various places is necessary along with traffic closure and the construction and work cannot be performed quickly.

  Therefore, when installing the laying cable C on the spiral hanger H installed at the refraction place as shown in FIG. 3 or FIG. 4, the laying cable support 10 as shown in FIG. 5 is used. Is effective.

  Next, the laying cable support 10 of this embodiment will be described. In FIG. 5, the laying cable support 10 includes, for example, a spiral hanger H supported by a messenger wire W laid so as to extend in a direction orthogonal to a utility pole D installed at a corner of a road. And a plurality of attachments 12 for attaching the tube guide 11 to the messenger wire W.

  The tube guide 11 is formed in a tube shape that defines a guide space Sg that is open at both ends and can be guided by being inserted through the wire tool 100, and is extended in the opening direction at both ends. In other words, the lines are formed so that the angle between the opening directions at both ends thereof is approximately 90 degrees so that the lines are orthogonal to each other on the intermediate side. For this reason, the tube guide 11 is set so that the opening direction of both ends thereof faces the opening direction of the end portion of the guide space Sh of the spiral hanger H supported by the messenger wire W extending in the orthogonal direction. It can be attached to the wire W. In addition, since the tube guide 11 has a simple tube shape structure, it can be manufactured at low cost simply by molding a metal material, a resin material, or the like into a tube shape.

  As shown in FIG. 6, the fixture 12 has a main body 13 formed in a ring shape having an inner diameter smaller than the outer diameter of the tube guide 11, and is slit so that the inner diameter of the main body 13 can be expanded. 13a is formed, and a pair of brim portions 14 extending outward from both sides of the slit 13a of the main body portion 13 and facing each other are formed. The flange portion 14 of the attachment portion 12 has screw holes that allow the bolts 15 to pass therethrough at two locations on the inner side and the outer side, and a nut 16 (see FIG. 6B) is screwed onto the bolt 15. Then, the outer periphery of the tube guide 11 can be fastened and fixed by the main body 13 by screwing so as to approach each other. Further, the messenger wire W can be accommodated and tightened on one brim portion 14 of the attachment portion 12 so as not to move between the screw holes (between the screwing position by the bolt 15 and the nut 16). Thus, a curved portion 14a is formed. The fixture 12 has a simple structure in which a metal material, a resin material, or the like is formed in a ring shape and the bolt 15 and the nut 16 are assembled to the flange portion 14, and thus can be manufactured at low cost.

  That is, in the laying cable support 10, the tube guide 11 constitutes a guide member, and the attachment member 12 uses a plurality of attachments 12, and each of two or more locations at both ends of the tube guide 11. Is fastened with the fixture 12 so that the entire tube guide 11 (at least both ends) can be attached in a posture parallel to the orthogonal messenger wire W and fixed to the same messenger wire W in the opening direction. Can be attached and fixed in such a manner that the ends of the spiral hanger H (guide space Sh) perpendicular to each other extend so that both end portions of the tube guide 11 face each other and the opening directions of the tube guides 11 coincide with each other. . As a result, the tube guide 11 can be attached to the orthogonal messenger wire W together with the spiral hanger H, and a refraction path through which the wire tool 100 is inserted and guided by the guide space Sg of the tube guide 11 can be defined.

  For this reason, for example, even when it is necessary to lay the laying cable C on the utility pole D installed at the corner of the road, the tool tip 103 of the wiring tool 100 is placed in the guide space Sh of the spiral hanger H on the upstream side. By inserting the lead wire 105 and inserting it into the tube guide 11 (inside the guide space Sg) from the guide space Sh of the spiral hanger H, it can be refracted, and the tool tip 103 can be refracted as it is. 11 (guide space Sg) can be passed (inserted) through the guide space Sh of the spiral hanger H on the downstream side, and the laying cable C is temporarily placed at the rear end of the lead wire 105 even in such a refracting path. Thus, the work of supporting and installing on the messenger wire W can be easily performed.

  Further, in this case, the laying cable C to be installed is housed in the tube guide 11, and the worker climbing on the utility pole D is not touched, and the worker uses the communication cable with care. You can focus on other tasks without having to.

  As described above, in this embodiment, both ends of the tube guide 11 are attached and fixed to the messenger wire W by the two attachments 12 even between the upstream and downstream ends of the orthogonal spiral hanger H. The spiral hanger H and the guide spaces Sh and Sg of the tube guide 11 can be smoothly communicated so that the wire tool 100 can be inserted and passed, and the laying cable C is supported by the messenger wire W and installed. Can be completed easily. Since the tube guide 11 and the fixture 12 are inexpensive and lightweight, they can be fixed to the messenger wire W, and can be reused as they are when the laying cable C is added.

  Here, the case where the messenger wire W is installed on the utility pole D at the corner of the road and the guide space Sh of the spiral hanger H is orthogonal is described as an example, but the present invention is not limited to this, and is shown in FIG. Thus, it can install similarly also with respect to the spiral hanger H installed in the messenger wire W constructed so as to be orthogonal in the space on the road intersection.

  Therefore, the work of laying the laying cable C between the power poles D can be performed easily and at a low cost without climbing the power pole D or blocking the road and using an aerial work vehicle. It can be used as it is when adding more.

  Next, FIG. 7 is a figure which shows 2nd Embodiment of the laying cable support tool based on this invention. Here, since the present embodiment is configured in the same manner as the above-described embodiment, the same components are denoted by the same reference numerals and the characteristic portions will be described (the same applies to other embodiments described below). .

  In FIG. 7, the fixture 22 constitutes the laying cable support 10 together with the tube guide 11 in place of the fixture 12 of the above-described embodiment, and this fixture 22 forms a slit 23a so that the inner diameter can be expanded. The flanges 14 are formed at both ends of the cylindrical main body 23.

  That is, the fixture 22 is designed to have a structure in which the flange portions 14 are disposed at both ends of a cylindrical main body portion 23 in which the main body portion 13 of the fixture 12 of the above-described embodiment is continuous, as shown in FIG. Thus, it can function similarly to the two fixtures 12 adjacent at both ends of the tube guide 11. In short, the fixture 22 constitutes an attachment member and fastens and fixes both ends of the tube guide 11, and both ends of the tube guide 11 can be attached in a posture parallel to the messenger wire W. Both ends of 11 can be fixed so that the opening directions of the spiral hanger H (guide space Sh) perpendicular to the opening direction face each other and approach each other.

  Therefore, even in the laying cable support 10 of the present embodiment, the messenger wire W laid on the power pole D at the corner of the road or the messenger wire W laid so as to intersect in the space on the road intersection. The both ends of the tube guide 11 can be attached and fixed by the fixture 22. As a result, the spiral hanger H installed on the messenger wire W and the guide spaces Sh and Sg of the tube guide 11 can be smoothly communicated so that the passing tool 100 can be smoothly inserted and passed, and the laying cable C The work of supporting and erection can be easily performed. Since the tube guide 11 and the fixture 22 are inexpensive and lightweight, they can be fixed to the messenger wire W, and can be reused as they are when the laying cable C is added.

  Thus, also in this embodiment, the same operation effect as the above-mentioned embodiment can be obtained.

Next, FIG. 8 is a figure which shows 3rd Embodiment of the laying cable support tool based on this invention.
In FIG. 8, the fixture 32 constitutes the laying cable support 10 together with the tube guide 11 instead of the fixture 22 of the above-described embodiment, and this fixture 32 is formed by the slit 23 a of the cylindrical main body 23. A pair of brim portions 34 extending outward from both sides and facing each other are formed.

  The flange portion 34 of the fixture 32 has bolts 15 and nuts 16 at both the inner and outer portions (see FIG. 6 (b)), similar to the flange portion 14 in the above-described embodiment, at both ends and the central portion. A screw hole (not shown) is opened so that it can be screwed, and the messenger wire W is not moved between the screw holes of one brim portion 34 (between the screwing position by the bolt 15 and the nut 16). A curved portion 34a is formed so that it can be mounted and tightened.

  That is, the fixture 32 is designed to have a structure in which the flange portion 14 of the fixture 22 of the above-described embodiment is continuous and screwed and fixed at both ends and the center portion. As shown in FIG. It can function in the same way as two fixtures 12 adjacent at both ends. In short, the fixture 32 can constitute an attachment member to fasten and fix both ends of the tube guide 11 and attach both ends of the tube guide 11 in a posture parallel to the messenger wire W. Both end portions of the spiral hanger H (guide space Sh) perpendicular to the opening direction face each other and approach each other, and can be fixed so that their opening directions coincide with each other.

  Therefore, even in the laying cable support 10 of the present embodiment, the messenger wire W laid on the power pole D at the corner of the road or the messenger wire W laid so as to intersect in the space on the road intersection. The both ends of the tube guide 11 can be attached and fixed by the fixture 32. As a result, the spiral hanger H installed on the messenger wire W and the guide spaces Sh and Sg of the tube guide 11 can be smoothly communicated so that the passing tool 100 can be smoothly inserted and passed, and the laying cable C The work of supporting and erection can be easily performed. Since the tube guide 11 and the fixture 32 are inexpensive and light, they can be fixed to the messenger wire W and can be reused as they are when the laying cable C is added.

  Thus, also in this embodiment, the same operation effect as the above-mentioned embodiment can be obtained.

  Here, in this embodiment, the case where the main body portion 23 of the fixture 32 is formed in a simple cylindrical shape will be described as an example. However, the present invention is not limited to this. For example, as shown in FIG. You may form the nail | claw 23b which protrudes inward in the one end part of the main-body part 23. FIG. In this case, even if the tube guide 11 to be fastened and fixed in the main body 23 is deteriorated with age and the tightening becomes loose, as shown in FIG. It is possible to limit the displacement in the extending direction by facing the claw 23b. Needless to say, the claw 23b may be formed on the main body portions 13 and 23 of the fixtures 12 and 22 of the first and second embodiments described above.

Next, FIG. 10 is a figure which shows 4th Embodiment of the laying cable support tool based on this invention.
In FIG. 10, the tube guide 11 constituting the laying cable support 10 is formed in an opening portion where both end portions 11a are wider than the intermediate portion 11b, and the end of the spiral hanger H is formed inside the both end portions 11a. It is designed so that it can be installed between the upstream side and the downstream side with the part inserted.

  Therefore, in the laying cable support 10 of this embodiment, the end portions of the spiral hanger H can be inserted into the both end portions 11a of the tube guide 11 so that the guide spaces Sg and Sh can be connected without gaps. The guide spaces Sg and Sh can be easily transferred and smoothly guided without causing the tool tip 103 of the line tool 100 to be disengaged to the outside.

  Thus, in this embodiment, the same effect as the above-mentioned embodiment can be obtained, and in addition to this, the passing tool 100 can be smoothly delivered by the both end portions 11a of the tube guide 11 opened, The installation work of the laying cable C can be easily completed.

Next, FIG. 11 is a figure which shows 5th Embodiment of the laying cable support tool based on this invention.
In FIG. 11, the tube guide 41 constitutes the laying cable support 10 together with the fixture 22 (the fixtures 12 and 32 may be used) instead of the tube guide 11 of the above-described embodiment. By being formed into a bellows shape with an opening, a guide space Sg that can be freely bent is defined inside.

  That is, the tube guide 41 is clamped and fixed at both ends by the fixture 22, and, for example, according to the circumstances of the installation location, the crossing angle of the extension line in the opening direction at both ends is approximately 90 degrees. The tube guide 41 can be attached in a posture parallel to the messenger wire W while being bent, and both ends of the tube guide 41 face each other and approach each other at the end of the spiral hanger H (guide space Sh) orthogonal to the opening direction. Can be fixed so that their opening directions coincide.

  Therefore, even in the laying cable support 10 of the present embodiment, the messenger wire W laid on the power pole D at the corner of the road or the messenger wire W laid so as to intersect in the space on the road intersection. The both ends of the tube guide 41 can be attached and fixed by the fixture 22 while being bent easily. As a result, the spiral hanger H installed on the messenger wire W and the guide spaces Sh and Sg of the tube guide 41 can be smoothly communicated so that the wiring tool 100 can be smoothly inserted and passed, and the laying cable C The work of supporting and erection can be easily performed. Since the tube guide 41 and the fixture 22 are inexpensive and lightweight, they can be fixed to the messenger wire W, and can be reused as they are when the laying cable C is added.

  Thus, in this embodiment, the same operation effect as the above-mentioned embodiment can be obtained, and in addition, since the tube guide 41 can be bent freely, the messenger wire W having a different crossing angle can be used. Can also be attached, and it is not necessary to prepare ones having different bending angles, and the cost can be further reduced.

  Next, FIGS. 12 and 13 are views showing a sixth embodiment of the laying cable support according to the present invention.

  In FIG. 12, the tube guide 51 constitutes the laying cable support 10 together with the fixture 32 (the fixtures 12 and 22) instead of the tube guide 11 of the above-described embodiment, and the tube guide 51 is flexible. In a natural state (a state where no bending load or the like is applied) is formed by molding a resin material having properties, it is formed into a tube shape that curves so that the extension lines in the opening direction at both ends intersect at an obtuse angle .

  This tube guide 51 is formed so that it can be divided into two parts by forming two splits extending between the end sides 51a at both ends on both sides centering on the axis. One side of each part is connected by a hinge 52 so that the internal guide space Sg can be opened and closed. The tube guide 51 can be opened and closed using a hinge 52. However, the present invention is not limited to this, and the tube guide 51 may be opened and closed as a thin hinge portion.

  In other words, the tube guide 51 is clamped and fixed at both ends by the fixture 32, and, for example, the crossing angle of the extension line in the opening direction at both ends is approximately 90 degrees according to the circumstances of the installation location. The tube guide 51 can be attached in a posture parallel to the messenger wire W while being bent, and both ends of the tube guide 51 face each other and approach each other to the end of the spiral hanger H (guide space Sh) orthogonal to the opening direction. Can be fixed so that their opening directions coincide.

  Therefore, even in the laying cable support 10 of the present embodiment, the messenger wire W laid on the power pole D at the corner of the road or the messenger wire W laid so as to intersect in the space on the road intersection. Both ends of the tube guide 51 can be attached and fixed by the fixture 32 while bending the tube guide 51 easily. As a result, the spiral hanger H installed on the messenger wire W and the guide spaces Sh and Sg of the tube guide 51 can be smoothly communicated so that the wiring tool 100 can be inserted and passed smoothly. The work of supporting and erection can be easily performed. Since the tube guide 51 and the fixture 32 are inexpensive and lightweight, they can be fixed to the messenger wire W, and can be reused as they are when the laying cable C is added.

  Further, since the tube guide 51 can be divided into two by a hinge 52 to open and close the internal guide space Sg, the laying cable C that is already inserted into the spiral hanger H and supported by the messenger wire W is provided. Can also be attached to the messenger wire W, after which the laying cable C is installed in the guide space Sh and then both ends are fastened and fixed by the fixtures 32. The cable C can be smoothly inserted into and passed through the guide space Sg in the tube guide 51 by the passing tool 100 and supported by the messenger wire W.

  Further, as shown in FIG. 13A, the tube guide 51 is attached by the fixture 32 even between the spiral hangers H supported by the messenger wire W installed in a straight line adjacent to the utility pole D. Both ends can be fastened and fixed in a straight line so that the extension line in the opening direction at both ends is approximately 180 degrees, and can be attached in a posture parallel to the messenger wire W. Similarly, FIG. As shown in Fig. 2, even between the spiral hangers H supported by the straight messenger wires W laid on both sides of the utility pole D, they are curved so as to bypass the circumference of the utility pole D and the openings at both ends thereof It can also be attached in a posture that is parallel to the messenger wire W while being linear so that the extension line of the direction becomes approximately 180 degrees. Can be bridged by supported messenger wire W is smoothly is inserted, passing into the guide space Sg in the tube guide 51 Bull C by Tsusen tool 100.

  Thus, in this embodiment, the same operation effect as the above-mentioned embodiment can be obtained, and in addition, since the tube guide 51 can be easily bent, the messenger wires W having different crossing angles can be used. Can also be attached, and it is not necessary to prepare ones having different bending angles, and the cost can be further reduced. Further, the tube guide 51 can be installed and attached to the messenger wire W without cutting the existing laying cable C by opening and closing the internal guide space Sg. It can also be inserted and passed through the space Sg.

  Here, in this embodiment, the tube guide 51 is formed with two splits on the outer peripheral surface so that the internal guide space Sg can be opened and closed. However, the present invention is not limited to this, and the split is divided into one slit. It is also possible to make the laying cable C interiorable in the internal guide space Sg while expanding the split.

  Next, FIGS. 14 and 15 are views showing a seventh embodiment of the laying cable support according to the present invention.

  In FIG. 14, the laying cable support 60 is attached to the messenger wire W and the spiral guide 61 attached between the spiral hangers H supported by the messenger wire W that intersects in the space on the road intersection, for example. A support steel wire 62 that maintains the posture of the spiral guide 61, and a plurality of crimping members 63 that connect the spiral guide 61 and the support steel wire 62 to the messenger wire W and the spiral hanger H. It is configured. In this laying cable support 60, the peripheral line material 61a of the spiral guide 61, the support steel wire 62, the messenger wire W, and the peripheral line material h of the spiral hanger H are each a wire material, so that a general caulking material 63 is used. Can be connected and connected.

  Similar to the spiral hanger H, the spiral guide 61 spirally surrounds the circumferential line member 61a so as to define a guide space Sg that is open at both ends and can be guided by being inserted through the wire tool 100. The guide space Sg is bent so that, for example, the crossing angle of the extension line in the opening direction at both ends thereof is approximately 90 degrees, depending on the circumstances of the installation location, etc. In a posture parallel to the messenger wire W, the peripheral line material 61a can be connected to the peripheral line material h of the spiral hanger H by the caulking material 63, and both ends of the spiral guide 61 are orthogonal to the opening direction. The ends of the spiral hanger H (guide space Sh) can be connected and fixed so as to face each other and approach each other so that their opening directions coincide with each other.

  Further, the spiral guide 61 is packed so that the circumferential pitch pg of the peripheral line member 61a does not allow the tool tip 103 of the line tool 100 that has been inserted and passed through the guide space Sh of the spiral hanger H to enter and come out. The tool tip 103 of the wire passing tool 100 entering from the spiral hanger H is designed to be able to slide so as to slide while abutting against the circumferential line material 61a that defines the guide space Sg. .

  Further, as shown in FIG. 15, in the spiral guide 61, a plurality of pipe members 64 formed in a cylindrical shape having a drum-shaped outer diameter formed so as to increase in diameter toward both ends are rotated to the peripheral line member 61a. The pipe member 64 covers the circumferential line member 61a from one end side to the other end side. In other words, the pipe member 64 constitutes the entire inner surface of the guide space Sg in the spiral guide 61. Is provided.

  The supporting steel wire 62 is connected and fixed by two caulking materials 63 in a posture that is curved and parallel along the messenger wire W that is orthogonal to each other, and has sufficient strength and is installed inside the spiral guide 61. By doing so, the spiral guide 61 is designed to maintain a posture parallel to the messenger wire W.

  That is, the spiral guide 61 (circumferential line material 61a) constitutes a guide member, the support steel wire 62 constitutes a support member, and the crimping material 63 constitutes an attachment member. The support 60 can also be attached to the entire spiral guide 61 in a posture parallel to the orthogonal messenger wire W, and is fixed to the same messenger wire W, and the spiral hanger H that is orthogonal to the extension line in the opening direction. It can be attached and fixed to the end portion of the (guide space Sh) so that both end portions of the spiral guide 61 face each other and the opening directions thereof coincide with each other. As a result, a spiral guide 61 is attached to the orthogonal messenger wire W together with the spiral hanger H, and a refraction path through which the wire tool 100 is inserted and guided by the guide space Sg of the spiral guide 61 can be defined. .

  For this reason, for example, even when it is necessary to lay the laying cable C in the space on the road intersection, the lead wire 103 is inserted into the guide space Sh of the spiral hanger H on the upstream side by inserting the tool tip 103 of the line tool 100. By feeding out 105, it can be made to enter into the spiral guide 61 (inside the guide space Sg) from the guide space Sh of the spiral hanger H and be refracted, and the tool tip 103 can be refracted as it is. From the space Sg), it can be passed (inserted) through the guide space Sh of the spiral hanger H on the downstream side, and the laying cable C is temporarily connected to the rear end of the lead wire 105 even in such a refracting path. By doing so, the laying cable C can be supported and installed on the messenger wire W.

  At this time, the wire passing tool 100 is moved in the circumferential direction so as to be in sliding contact with the small diameter portion 64a of the pipe member 64 (between the large diameter portions 64b of the pipe member 64) in the guide space Sg of the spiral guide 61. It can be inserted and passed smoothly so that it will not enter. The laying cable C can be supported on the messenger wire W and installed. The spiral guide 61 and the support steel wire 62 are obtained by processing a wire material such as a metal material or a resin material into a simple structure, and the caulking material 63 is a general-purpose material, and the pipe member 64 is easily resin-molded. Therefore, it can be manufactured at low cost, and since it is lightweight, it can be fixed to the messenger wire W and can be reused as it is when the laying cable C is added.

  Thus, in this embodiment, the same effect as the above-mentioned embodiment can be obtained, and in addition to this, the spiral guide 61 can be freely bent, so that the messenger wires W having different crossing angles can be obtained. It is not necessary to prepare ones having different bending angles, and the cost can be further reduced. Further, the spiral guide 61 is not limited to the messenger wire W laid so as to intersect in the space on the road intersection, but also to the messenger wire W laid on the power pole D at the corner of the road. Needless to say, it can be attached to.

  Here, in this embodiment, a case where a drum-shaped cylindrical pipe member 64 having both ends formed in a large diameter is rotatably mounted on the circumferential line member 61a of the spiral guide 61 will be described as an example. The member is not limited to the drum shape, and for example, a cylindrical pipe member having both end sides smaller in diameter than the intermediate portion may be externally mounted on the circumferential line member 61a. In this case, it is preferable to form parallel portions with the same diameter on both end sides so that the wire tool 100 can be received.

Next, FIG. 16 is a figure which shows 8th Embodiment of the laying cable support tool based on this invention.
In FIG. 16, the supporting steel wire 72 constitutes a laying cable support 60 together with the spiral guide 61 and the caulking material 63 by constituting a supporting member together with the supporting steel wire 62 of the above-described embodiment. The wire 72 is attached so as to connect the intersecting position of the messenger wire W and the intermediate portion of the support steel wire 62 so as to maintain the posture of the spiral hanger H in parallel with the messenger wire W.

  Thereby, in the laying cable support tool 60 of this embodiment, the vicinity of the top of the support steel wire 62 that supports the spiral guide 61 (circumferential line material 61a) in a bent shape is connected to the messenger wire W by the support steel wire 72 and supported. can do.

  Thus, in this embodiment, the same effect as the above-mentioned embodiment can be obtained, and in addition to this, the support steel wire 72 assists the support steel wire 62 that supports the attitude of the spiral hanger H. In addition, it is possible to more reliably avoid that the spiral guide 61 hangs down between the ends of the spiral hanger H, and to maintain the posture of the guide space Sg defined therein, and It can guide more smoothly.

  Here, in this embodiment, the case where one support steel wire 72 is connected to the intersection position of the messenger wire W will be described as an example. However, the present invention is not limited to this. For example, the messenger wire W is connected to the intersection position. When there is a metal fitting to be fixed, one support steel wire 72 may be connected to a location adjacent to the crossing position, or two support steel wires 72 may be connected to both sides of the crossing position. Needless to say.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.
