Description
この発明は、地線や電力線を懸垂支持する懸垂装置に関する。 The present invention relates to a suspension device that supports a ground line and a power line in a suspended manner.
鉄塔等に地線や電力線を懸垂支持するには、例えば、図９（ａ）（ｂ）に示すような懸垂装置が用いられる。この懸垂装置は、被取付体１００への取り付けに供される懸垂装置取付金具１０１に１枚リンク１０２を介してフリーセンター型懸垂クランプ１０３を連結することで構成されている。 In order to suspend and support a ground wire or a power line on a steel tower or the like, for example, a suspension device as shown in FIGS. 9A and 9B is used. This suspension device is configured by connecting a free center type suspension clamp 103 via a single link 102 to a suspension device mounting bracket 101 used for attachment to the body 100.
ところで、鉄塔等の被取付体１００に架線された地線や電力線は、風雨等の外力を受けて揺動することから、懸垂装置はその揺動に追随することのできる構成とされている。具体的には、懸垂装置取付金具１０１の直角クレビスリンク１０４と１枚リンク１０２、１枚リンク１０２とフリーセンター型懸垂クランプ１０３とがそれぞれ支軸１０５、１０６によって回動可能に連結されている。 By the way, since the ground wire and power line wired to the to-be-attached body 100, such as a steel tower, rock | fluctuate in response to external force, such as a wind and rain, it is set as the structure which can follow the rocking | fluctuation apparatus. Specifically, the right-angle clevis link 104, the one-piece link 102, the one-piece link 102, and the free center type suspension clamp 103 of the suspension device mounting bracket 101 are rotatably connected by the support shafts 105 and 106, respectively.
ところが、地線や電力線が線方向に揺動した場合においては、図１０に示すように、地線や電力線の線方向に回動可能とされた上記２箇所の回動連結部のうち、最も上側（鉄塔側）に位置する回動連結部、すなわち、直角クレビスリンク１０４と１枚リンク１０２とを連結する回動連結部のみが回動する構成であるため、この部分に回動による摩耗が集中し、１枚リンク１０２や当該支軸１０５の強度低下を招いていた。 However, when the ground wire or power line swings in the line direction, as shown in FIG. 10, the most of the two rotation connecting portions that are rotatable in the line direction of the ground wire or power line. Since only the rotation connecting portion located on the upper side (steel tower side), that is, the rotation connecting portion connecting the right angle clevis link 104 and the one-piece link 102 is rotated, wear due to the rotation is generated in this portion. The concentration of the single link 102 and the support shaft 105 was reduced.
そのため、従来、当該部品の定期的な検査及び交換を行っていたが、部品交換にあたっては、地線や電力線を懸垂した状態で行わなければならない上に、鉄塔上といった高所での作業となるため、非常に煩雑で手間のかかる作業となっていた。 Therefore, in the past, regular inspection and replacement of the parts have been carried out. However, when replacing the parts, the ground lines and power lines must be suspended, and the work is performed at a high place on the steel tower. For this reason, the operation is very complicated and time-consuming.
そこで、この発明は、上記課題を解決するためになされたものであって、回動による摩耗の進行を遅延させ、部品交換の回数を減少させることのできる懸垂装置の提供を目的とする。 Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a suspension device that can delay the progress of wear due to rotation and reduce the number of parts replacement.
上記課題を解決するため、本発明の懸垂装置は、地線又は電力線を被取付体２に懸垂支持する懸垂装置であって、上記被取付体２への取り付けに供される取付具１０と、上記地線又は上記電力線を把持するクランプ３０と、上記取付具１０と上記クランプ３０とを連結する連結部材２０、４０、５０とを備え、上記取付具１０と上記連結部材２０、４０、５０、上記連結部材２０、４０、５０と上記クランプ３０とがそれぞれ回動可能に連結されているとともに、上記回動連結部のうち、上記取付具１０と連結部材２０、４０、５０との回動連結部に回動範囲を規制する回動範囲規制手段を設けていることを特徴としている。 In order to solve the above-described problem, the suspension device of the present invention is a suspension device that suspends and supports a ground wire or a power line on the attached body 2, and a fixture 10 that is provided for attachment to the attached body 2; A clamp 30 for holding the ground wire or the power line; and connecting members 20, 40, 50 for connecting the fixture 10 and the clamp 30, the fixture 10 and the connecting members 20, 40, 50, The connecting members 20, 40, 50 and the clamp 30 are connected to each other so as to be rotatable, and of the rotating connecting portions, the fitting 10 and the connecting members 20, 40, 50 are connected to each other. A rotation range restricting means for restricting the rotation range is provided in the part.
具体的には、上記取付具１０と連結部材２０、４０、５０との回動連結部は、上記取付具１０又は上記連結部材２０、４０、５０のどちらか一方に設けられたクレビス部１２ｂ、４０ａに、他方の端部を介在させるとともに、上記取付具１０及び上記連結部材２０、４０、５０に跨って支軸２１を挿通することで構成され、回動範囲規制手段は、上記クレビス部１２ｂ、４０ａの股部１２ｃ、４０ｃと、他方の一方側端部に設けられ、他方が一方に対して所定角度以上、相対的に回動することで上記股部１２ｃ、４０ｃに当接する突出部１７ｂ、２０ｂ、５０ｂとから構成されている。 Specifically, the rotation connecting portion between the fixture 10 and the connecting members 20, 40, 50 is a clevis portion 12b provided on either the fixture 10 or the connecting members 20, 40, 50, The other end portion is interposed in 40a, and the support shaft 21 is inserted across the fixture 10 and the connecting members 20, 40, 50, and the rotation range restricting means includes the clevis portion 12b. , 40a crotch parts 12c, 40c and the other one side end part, and the other part is relatively rotated by a predetermined angle or more with respect to the other so that the protruding part 17b contacts the crotch parts 12c, 40c. , 20b, 50b.
または、回動範囲規制手段は、上記取付具１０又は上記連結部材２０、４０、５０のどちらか一方に設けられた長孔１７ｃと、この長孔１７ｃに挿通された状態で他方に固定され、他方が一方に対して所定角度以上、相対的に回動することで上記長孔１７ｃの終端部に当接する突起１８とから構成されている。 Alternatively, the rotation range restricting means is fixed to the other in the state of being inserted into the long hole 17c and the long hole 17c provided in one of the fitting 10 or the connecting members 20, 40, 50, The other is composed of a protrusion 18 that abuts against the end portion of the elongated hole 17c by rotating relative to the other by a predetermined angle or more.
この発明の懸垂装置によれば、取付具と連結部材との回動連結部に、回動範囲を規制する回動範囲規制手段を備えているため、回動範囲を超えて回動する場合には、取付具と連結部材との回動連結部に代わって、連結部材とクランプとの回動連結部が回動することとなる、すなわち、取付具と連結部材との回動連結部のみに集中していた摩耗を、連結部材とクランプとの回動連結部にも分担させることができるため、回動による摩耗の進行を遅延させることができ、部品交換の回数を減少させることができる。 According to the suspension device of the present invention, the rotation connecting portion between the fixture and the connecting member is provided with the rotation range restricting means for restricting the rotation range. Instead of the pivotal connecting part between the fixture and the coupling member, the pivotal coupling part between the coupling member and the clamp will be rotated, that is, only in the pivotal coupling part between the fixture and the coupling member. Since the concentrated wear can be shared by the rotation connecting portion between the connecting member and the clamp, the progress of wear due to the rotation can be delayed, and the number of parts replacement can be reduced.
次に、この発明の懸垂装置の実施形態を図面に基づいて詳細に説明する。図１（ａ）（ｂ）は、この発明の懸垂装置の第１の実施形態を示している。この懸垂装置１は、装置の鉄塔等の被取付体２への取り付けに供される懸垂装置取付金具１０に対して１枚リンク２０を介してフリーセンター型懸垂クランプ３０を連結することで構成されている。以下、個々の構成部材について具体的に説明する。 Next, an embodiment of the suspension device of the present invention will be described in detail with reference to the drawings. 1 (a) and 1 (b) show a first embodiment of the suspension device of the present invention. The suspension apparatus 1 is configured by connecting a free center suspension clamp 30 via a single link 20 to a suspension apparatus mounting bracket 10 that is used for attachment of the apparatus to a mounted body 2 such as a steel tower. ing. Hereinafter, each component member will be specifically described.
懸垂装置取付金具１０は、鉄塔等の被取付体２の下面に固定される取付座１１と、取付座１１に回動可能に連結された直角クレビスリンク１２とから構成されている。具体的には、取付座１１は、略中心部に孔（図示しない）が設けられた略方形とされており、図１（ａ）において下面側から一対の軸受部１１ａ、１１ａが延設されている。一対の軸受部１１ａ、１１ａには支軸挿通用の孔が設けられており、一対の軸受部１１ａ、１１ａ間に直角クレビスリンク１２のリンク部１２ａを介在させるとともに、リンク部１２ａに設けられた孔と軸受部１１ａ、１１ａの孔とを対向させ、これら孔にボルト（支軸）１３を挿通、ナット１４を螺合することで、回動可能に連結されている。なお、一対の軸受部１１ａ、１１ａは地線（図示しない）の線方向と略平行に並設されており、直角クレビスリンク１２は、地線の線方向に対して略直交する方向に回動可能とされている。また、取付座１１は、被取付体２に予め設けられている孔と、取付座１１の四隅に設けられている孔とにボルト１５・・を挿通、ナット１６・・を螺合することによって、被取付体２の下面側に固定されている。 The suspension device mounting bracket 10 includes a mounting seat 11 that is fixed to the lower surface of the mounted body 2 such as a steel tower, and a right-angle clevis link 12 that is rotatably connected to the mounting seat 11. Specifically, the mounting seat 11 has a substantially square shape with a hole (not shown) provided in a substantially central portion, and a pair of bearing portions 11a and 11a are extended from the lower surface side in FIG. ing. The pair of bearing portions 11a, 11a are provided with holes for inserting support shafts. The link portion 12a of the right-angle clevis link 12 is interposed between the pair of bearing portions 11a, 11a, and the link portion 12a is provided. The holes and the holes of the bearing portions 11a and 11a are opposed to each other, and bolts (support shafts) 13 are inserted into these holes and nuts 14 are screwed together so as to be rotatably connected. The pair of bearing portions 11a and 11a are arranged in parallel to the line direction of the ground line (not shown), and the right-angle clevis link 12 rotates in a direction substantially orthogonal to the line direction of the ground line. It is possible. Further, the mounting seat 11 is inserted by inserting bolts 15... Into the holes provided in the mounted body 2 in advance and the holes provided in the four corners of the mounting seat 11 and screwing the nuts 16. These are fixed to the lower surface side of the mounted body 2.
また、直角クレビスリンク１２の下側に設けられたクレビス部１２ｂに、１枚リンク２０を介在させるとともに、クレビス部１２ｂの孔と１枚リンク２０の孔とにボルト（支軸）２１を挿通、ナット２２を螺合することで、直角クレビスリンク１２に対して１枚リンク２０が回動可能に連結されている。なお、１枚リンク２０の回動方向は、直角クレビスリンク１２の回動方向とは略直交する方向とされ、地線の線方向に略平行な方向に回動可能とされている。 In addition, a single link 20 is interposed in the clevis portion 12b provided on the lower side of the right-angle clevis link 12, and a bolt (support shaft) 21 is inserted through the hole of the clevis portion 12b and the hole of the single link 20, The single link 20 is rotatably connected to the right-angle clevis link 12 by screwing the nut 22. The rotation direction of the single link 20 is a direction substantially orthogonal to the rotation direction of the right-angle clevis link 12, and is rotatable in a direction substantially parallel to the line direction of the ground line.
１枚リンク２０の下側には、１枚リンク２０を挟むようにして、フリーセンター型懸垂クランプ３０の吊金具３１、３１が連結されている。１枚リンク２０と吊金具３１、３１においても、それぞれの孔にボルト（支軸）３２を挿通、ナット３３を螺合することで回動可能に連結している。なお、吊金具３１の回動方向は、１枚リンク２０の回動方向と同方向とされている。 Suspension fittings 31 of a free center type suspension clamp 30 are connected to the lower side of the single link 20 so as to sandwich the single link 20. Also in the single link 20 and the hanging metal fittings 31, 31, bolts (support shafts) 32 are inserted into the respective holes, and nuts 33 are screwed together so as to be rotatable. In addition, the rotation direction of the hanging bracket 31 is the same as the rotation direction of the single link 20.
一対の吊金具３１、３１は、図１（ｂ）に示すように、下方に向かうに従って互いに離間する方向に広がる形状とされており、その広がった部分の間に、クランプ本体３４が回動可能に連結されている。そして、クランプ本体３４の上部には、地線をクランプ本体３４との間で把持するための押え金具３５がボルト３６・・及びナット３７・・によって連結されている。 As shown in FIG. 1 (b), the pair of hanging brackets 31 and 31 has a shape that widens in a direction away from each other as it goes downward, and the clamp body 34 is rotatable between the widened portions. It is connected to. A clamp 35 for holding the ground wire with the clamp body 34 is connected to the upper portion of the clamp body 34 by bolts 36 and nuts 37.
上記構成の懸垂装置１は、懸垂装置取付金具１０を鉄塔等の被取付体２に固定するとともに、フリーセンター型懸垂クランプ３０のクランプ本体３４と押え金具３５とで地線を把持することにより、地線を被取付体２に懸垂支持する。 The suspending device 1 having the above-described structure fixes the suspending device mounting bracket 10 to the mounted body 2 such as a steel tower and holds the ground wire with the clamp body 34 and the presser fitting 35 of the free center type suspending clamp 30. The ground wire is suspended and supported on the attached body 2.
ところで、従来の懸垂装置では、クランプ本体３４と押え金具３５とによって把持されている地線が線方向に揺動すると、線方向への回動を許容する回動連結部のうち、最も上部に位置する回動連結部、すなわち、直角クレビスリンク１２と１枚リンク２０とを連結するボルト２１を回動中心として装置が回動する構成とされていた。そのため、１枚リンク２０の孔やこの孔に挿通されているボルト２１に回動による摩耗が集中し、１枚リンク２０やボルト２１の強度低下を招いていた。 By the way, in the conventional suspension device, when the ground wire gripped by the clamp main body 34 and the presser fitting 35 swings in the linear direction, the uppermost of the rotational connection portions that allow the rotational movement in the linear direction. The apparatus is configured such that the apparatus rotates around a rotation connecting portion that is positioned, that is, a bolt 21 that connects the right-angle clevis link 12 and the single link 20. Therefore, wear due to the rotation is concentrated on the hole of the single link 20 and the bolt 21 inserted through the hole, and the strength of the single link 20 and the bolt 21 is reduced.
そこで、本発明の懸垂装置１においては、直角クレビスリンク１２に対する１枚リンク２０の回動範囲を規制する回動範囲規制手段を設けている。具体的には、１枚リンク２０の上端部両側に、ボルト直上部２０ａより回転半径を大とする突出部２０ｂ、２０ｂを設け、直角クレビスリンク１２に対して所定角度（例えば１５度）以上、１枚リンク２０が回動しようとすると、１枚リンク２０の上端部両側に設けた突出部２０ｂが直角クレビスリンク１２のクレビス部１２ｂの股部１２ｃに当接する構成としている。 Therefore, in the suspension device 1 of the present invention, a rotation range restricting means for restricting the rotation range of the single link 20 with respect to the right angle clevis link 12 is provided. Specifically, on both sides of the upper end of the single link 20 are provided protrusions 20b, 20b having a rotation radius larger than the bolt upper portion 20a, and a predetermined angle (for example, 15 degrees) or more with respect to the right angle clevis link 12. When the single link 20 tries to rotate, the protruding portions 20b provided on both sides of the upper end portion of the single link 20 are configured to contact the crotch portion 12c of the clevis portion 12b of the right angle clevis link 12.
この場合、直角クレビスリンク１２に対して所定角度以上、１枚リンク２０を回動させようとすれば、図２の一点鎖線で示すように、１枚リンク２０と吊金具３１、３１とを連結するボルト３２を回動中心として回動することとなり、２箇所の回動連結部で所望角度の回動を行うようになる。すなわち、回動による摩耗を２箇所に分散させることができ、１枚リンク２０やボルト２１の摩耗の進行を遅延させることができるのである。従って、１枚リンク２０やボルト２１の寿命を延ばすことができ、交換回数を減少させることができる。 In this case, if the one-piece link 20 is rotated by a predetermined angle or more with respect to the right-angle clevis link 12, the one-piece link 20 and the hanging brackets 31 and 31 are connected as shown by a one-dot chain line in FIG. Therefore, the rotation is performed at a desired angle by two rotation connecting portions. That is, wear due to rotation can be dispersed in two places, and the progress of wear of the single link 20 and the bolt 21 can be delayed. Accordingly, the lifetime of the single link 20 and the bolt 21 can be extended, and the number of replacements can be reduced.
図３（ａ）（ｂ）は、この発明の懸垂装置の第２の実施形態を示している。第２の実施形態の懸垂装置３においては、第１の実施形態の懸垂装置１と比較して、直角クレビスリンク１２が直角リンク１７に、１枚リンク２０が平行クレビス４０とされている点、相違している。 3 (a) and 3 (b) show a second embodiment of the suspension device of the present invention. In the suspension device 3 of the second embodiment, compared to the suspension device 1 of the first embodiment, the right angle clevis link 12 is a right angle link 17 and the one link 20 is a parallel clevis 40, It is different.
そして、第２の実施形態の懸垂装置３の回動範囲規制手段は、直角リンク１７の下端部両側に、ボルト直下部１７ａより回転半径を大とする突出部１７ｂ、１７ｂを設け、直角リンク１７に対して所定角度（例えば１５度）以上、平行クレビス４０が回動しようとすると、直角リンク１７の下端部両側の突出部１７ｂが、平行クレビス４０の上側クレビス部４０ａの股部４０ｃに当接することで構成されている。所定角度以上に回動する場合においては、図４の一点鎖線で示すように、平行クレビス４０と吊金具３１、３１とを連結するボルト（支軸）３２を回動中心として回動することとなる。なお、平行クレビス４０の下側クレビス部４０ｂには、図３（ｂ）に示すように、フリーセンター型懸垂クランプ３０と略同幅の間隔が設けられており、第１の実施形態において互いに離間する方向に広がって形成されていた一対の吊金具３１、３１はそれぞれ実直とされている。そのため、第２の実施形態の懸垂装置３においては、第１の実施形態の懸垂装置１と同様に、回動による摩耗を２箇所の回動連結部に分散させることができ、摩耗の進行を遅延させることができるといった効果を奏する他に、吊金具３１、３１間の間隔が地線の重みによって狭まるといった現象が起こらず、フリーセンター型懸垂クランプ３０の回動を良好に行うことができるとともに、クランプ本体３４によって地線を破損させる虞がないといった第１の実施形態の懸垂装置１では得られない効果を奏する。 The rotation range restricting means of the suspension device 3 according to the second embodiment is provided with protrusions 17b and 17b having a rotation radius larger than that of the bolt lower portion 17a on both sides of the lower end portion of the right angle link 17. When the parallel clevis 40 tries to rotate more than a predetermined angle (for example, 15 degrees), the protrusions 17b on both sides of the lower end portion of the right angle link 17 come into contact with the crotch portion 40c of the upper clevis portion 40a of the parallel clevis 40. It is composed of that. In the case of turning more than a predetermined angle, as shown by a one-dot chain line in FIG. 4, turning around a bolt (support shaft) 32 connecting the parallel clevis 40 and the hanging bracket 31, 31. Become. As shown in FIG. 3B, the lower clevis portion 40b of the parallel clevis 40 is provided with an interval substantially the same width as that of the free center suspension clamp 30, and is separated from each other in the first embodiment. Each of the pair of hanging brackets 31, 31 formed so as to spread in the direction to be made is straight. Therefore, in the suspension device 3 according to the second embodiment, similarly to the suspension device 1 according to the first embodiment, wear due to rotation can be distributed to two rotation connecting portions, and the progress of wear can be increased. In addition to the effect of being able to be delayed, the phenomenon that the distance between the hanging brackets 31, 31 is narrowed by the weight of the ground wire does not occur, and the free center type suspension clamp 30 can be rotated well. There is an effect that cannot be obtained by the suspension device 1 of the first embodiment, in which there is no possibility of damaging the ground wire by the clamp body 34.
図５（ａ）（ｂ）は、さらにこの発明の懸垂装置の第３の実施形態を示している。第３の実施形態の懸垂装置４においては、直角リンク１７と平行クレビス４０とを連結するボルト（支軸）２１の下方に、直角リンク１７と平行クレビス４０とを連結するボルト（突起）１８及びナット１９を設けている点、第２の実施形態と相違している。なお、新たに設けられたボルト１８を挿通するための孔１７ｃは、直角リンク１７側において、上方のボルト２１を回動中心とした際に描かれる円弧状の長孔とされている。そして、平行クレビス４０が直角リンク１７に対して所定角度（例えば１５度）以上回動しようとすると、円弧状の長孔１７ｃの終端部にボルト１８が当接し、回動範囲を規制している。所定角度以上の回動は、図６の一点鎖線で示すように、平行クレビス４０と吊金具３１、３１とを連結するボルト３２を回動中心として回動することとなる。このように、第３の実施形態の懸垂装置４においても、回動による摩耗を２箇所によって分散させることができ、摩耗の進行を遅延させることができる。なお、直角リンク１７にボルトを固定し、平行クレビス４０に円弧状の長孔を設けても良い。また、支軸２１の下方に突起１８を設けていたが、上方や左右に設けても良い。 FIGS. 5A and 5B further show a third embodiment of the suspension device of the present invention. In the suspension device 4 of the third embodiment, a bolt (protrusion) 18 for connecting the right angle link 17 and the parallel clevis 40 is provided below the bolt (support shaft) 21 for connecting the right angle link 17 and the parallel clevis 40. The point which provided the nut 19 is different from 2nd Embodiment. In addition, the hole 17c for inserting the newly provided bolt 18 is an arc-shaped elongated hole drawn when the upper bolt 21 is the center of rotation on the right-angle link 17 side. When the parallel clevis 40 attempts to rotate more than a predetermined angle (for example, 15 degrees) with respect to the right-angle link 17, the bolt 18 comes into contact with the terminal portion of the arc-shaped long hole 17c to restrict the rotation range. . As shown by the alternate long and short dash line in FIG. 6, the rotation of the predetermined angle or more turns around the bolt 32 that connects the parallel clevis 40 and the hanging brackets 31, 31. Thus, also in the suspension apparatus 4 of 3rd Embodiment, the abrasion by rotation can be disperse | distributed by two places, and progress of wear can be delayed. Note that a bolt may be fixed to the right-angle link 17 and an arc-shaped long hole may be provided in the parallel clevis 40. Further, although the protrusion 18 is provided below the support shaft 21, it may be provided above or on the left and right.
図７は、この発明の懸垂装置の第４の実施形態を示している。第４の実施形態の懸垂装置５においては、第１の実施形態において、１枚リンク２０の代わりに、ホーン取付金具５０が取り付けられ、その下側に碍子連５１、さらにその下側に平行クレビス５２を介してホーン取付金具５３が設けられている。すなわち、第１、第２、第３の実施形態の懸垂装置１、３、４は、絶縁体を介在しておらず、専ら地線懸垂支持用の懸垂装置であったが、第４の実施形態の懸垂装置５においては、電力線懸垂支持用とされているのである。第４の実施形態においては、回動範囲規制手段は、図７及び図８に示すように、ホーン取付金具５０の上端部両側に、ボルト直上部５０ａより回転半径を大とする突出部５０ｂ、５０ｂを設け、所定角度（例えば１５度）以上、ホーン取付金具５０が回動しようとすると、ホーン取付金具５０の上端部両側に設けた突出部５０ｂが直角クレビスリンク１２のクレビス部１２ｂの股部１２ｃに当接する構成とされている。従って、所定角度までは、ホーン取付金具５０が、直角クレビスリンク１２とホーン取付金具２０とを連結するボルト（支軸）２１を回動中心として回動するが、所定角度以上は、ホーン取付金具５０と碍子連５１とを連結するボルト（支軸）５４を回動中心として、碍子連５１が回動する構成となっている。そのため、上記第１、第２、第３の実施形態と同様に、回動による摩耗を２箇所によって分散させることができ、摩耗の進行を遅延させることができる。 FIG. 7 shows a fourth embodiment of the suspension device of the present invention. In the suspension device 5 of the fourth embodiment, a horn mounting bracket 50 is attached instead of the single link 20 in the first embodiment, and the insulator series 51 is provided below the parallel link clevis. A horn mounting bracket 53 is provided via 52. In other words, the suspension devices 1, 3, and 4 of the first, second, and third embodiments are suspension devices for supporting a ground wire suspension without using an insulator. In the suspension device 5 of the form, it is used for power line suspension support. In the fourth embodiment, as shown in FIG. 7 and FIG. 8, the rotation range restricting means is provided on both sides of the upper end portion of the horn mounting bracket 50 with protrusions 50b having a rotation radius larger than the bolt upper portion 50a. When the horn mounting bracket 50 is rotated by a predetermined angle (for example, 15 degrees) or more, the protrusions 50b provided on both sides of the upper end of the horn mounting bracket 50 are crotch portions of the clevis portion 12b of the right angle clevis link 12. It is set as the structure contact | abutted to 12c. Therefore, up to a predetermined angle, the horn mounting bracket 50 rotates around the bolt (support shaft) 21 that connects the right angle clevis link 12 and the horn mounting bracket 20, but the horn mounting bracket exceeds the predetermined angle. The lever series 51 is configured to rotate about a bolt (support shaft) 54 that connects 50 and the lever series 51. Therefore, similarly to the first, second, and third embodiments, wear due to rotation can be dispersed in two places, and the progress of wear can be delayed.
このように本発明の懸垂装置においては、地線や電力線の線方向の揺動による回動が、最も上側（被取付体２側）に位置する回動連結部、具体的には、懸垂装置取付金具１０の直角クレビスリンク１２（又は直角リンク１７）と、１枚リンク２０（又は平行クレビス４０、又はホーン取付金具５０）との回動連結部に集中することなく、この回動連結部より下側（地線や電力線側）の回動連結部にも分散されるため、回動による摩耗の進行を遅延させることができ、部品の寿命を延ばし、部品交換の回数を減少させることができる。 As described above, in the suspension apparatus of the present invention, the rotation by the swing of the ground line or the power line in the line direction is the rotation connecting portion located on the uppermost side (attached body 2 side), specifically, the suspension apparatus. Without concentrating on the rotating connecting portion between the right angle clevis link 12 (or the right angle link 17) of the mounting bracket 10 and the one-piece link 20 (or the parallel clevis 40 or the horn mounting bracket 50), Since it is also distributed to the lower (ground line or power line side) rotation connecting part, the progress of wear due to rotation can be delayed, the life of the part can be extended, and the number of parts replacement can be reduced. .
以上に、この発明の具体的な実施形態について説明したが、この発明は上記実施形態に限定されるものではなく、この発明の範囲内で種々変更して実施することが可能である。例えば、上記実施例においては、懸垂装置取付金具１０の直角クレビスリンク１２（又は直角リンク１７）と、１枚リンク２０（又は平行クレビス４０、又はホーン取付金具５０）との回動連結部に回動範囲規制手段を設けていたが、直角クレビスリンク１２や直角リンク１７が、地線や電力線の線方向に回動可能とされている場合には、直角クレビスリンク１２や直角リンク１７と取付座１１との回動連結部に回動範囲規制手段を設ける。すなわち、地線や電力線の線方向に回動可能とされた回動連結部のうち、最も被取付体２に近い回動連結部に回動範囲規制手段を設ける。また、上記実施例においては、回動範囲規制手段を１個設けていたが、回動連結部が３個以上ある場合には、取付座１１に近い回動連結部から順に複数の回動範囲規制手段を設けても良い。また、第３の実施形態で用いたボルト１８と長孔１７ｃとによる回動範囲規制手段を、第１の実施形態や第５の実施形態で用いても良い。すなわち、直角リンク１７と平行クレビス４０との回動連結部に用いる他に、直角クレビスリンク１２と１枚リンク２０（又はホーン取付金具５０）との回転連結部に用いても良い。また、回動範囲として１５度が例示されていたが、装置長や揺動幅等に合わせて適宜変更可能である。さらに、突出部１７ｂ、２０ｂ、５０ｂにおいては、股部１２ｃ、４０ｃと当接した際、互いに略平行となるように傾斜して形成されていたが、この形態である必要はなく、股部１２ｃ、４０ｃ側に突出させる等、適宜変更可能である。 Although specific embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example, in the above-described embodiment, the rotating clevis link 12 (or the right angle link 17) of the suspension device mounting bracket 10 and the single link 20 (or the parallel clevis 40 or the horn mounting bracket 50) are connected to the rotating connection portion. Although the movement range regulating means is provided, when the right-angle clevis link 12 or the right-angle link 17 is rotatable in the direction of the ground line or the power line, the right-angle clevis link 12 or the right-angle link 17 and the mounting seat are provided. A rotation range restricting means is provided at the rotation connecting portion with the rotation member 11. That is, the rotation range restricting means is provided in the rotation connecting portion that is closest to the mounted body 2 among the rotation connecting portions that can rotate in the direction of the ground line or the power line. In the above embodiment, one rotation range restricting means is provided. However, when there are three or more rotation connection portions, a plurality of rotation ranges are sequentially arranged from the rotation connection portion close to the mounting seat 11. A regulating means may be provided. Moreover, you may use the rotation range control means by the volt | bolt 18 and the long hole 17c which were used in 3rd Embodiment in 1st Embodiment or 5th Embodiment. In other words, in addition to being used for the rotation connecting portion between the right angle link 17 and the parallel clevis 40, the rotation connecting portion between the right angle clevis link 12 and the single link 20 (or the horn mounting bracket 50) may be used. Further, although 15 degrees is exemplified as the rotation range, it can be appropriately changed according to the apparatus length, the swinging width, and the like. Further, the protrusions 17b, 20b, and 50b are formed so as to be inclined so as to be substantially parallel to each other when they are in contact with the crotch parts 12c and 40c. , 40c, and the like can be appropriately changed.
また、上記実施例においては、支軸２１、３２、５４としてボルトを使用していたが、ボルトに限らず、シャフト等種々の公知のものを使用可能である。また、２個の部材に跨って支軸を挿通させることで回動連結部を構成していたが、これに限らず、種々の公知の回動機構を用いても良い。また、地線または電力線を把持するためにフリーセンター型懸垂クランプ３０を用いていたが、地線または電力線を支持できる構成のものであれば、上記に限らず適宜使用可能である。 Moreover, in the said Example, although the volt | bolt was used as the spindles 21, 32, and 54, not only a volt | bolt but various well-known things, such as a shaft, can be used. Moreover, although the rotation connection part was comprised by inserting a spindle over two members, it is not restricted to this, You may use various well-known rotation mechanisms. Moreover, although the free center type suspension clamp 30 was used to hold the ground line or the power line, any structure that can support the ground line or the power line is not limited to the above and can be used as appropriate.
