Description
本考案は架線吊具に関し、特に、き電線がいし取替作業等に使用する架線吊具に関するものである。 The present invention relates to an overhead wire suspension, and more particularly to an overhead wire suspension used for a feeder replacement work or the like.
き電線、き電分岐線や、トロリー線、ちょう架線、ハンガーのような電車線はレールに対応して、複数の支柱のビームや腕金(以下腕金等)に支持されている。 Wires, feeder branch lines, trolley lines, overhead lines, and hanger-like train lines are supported by a plurality of support beams and braces (hereinafter referred to as braces) corresponding to the rails.
き電線(架線)と腕金等の間を絶縁するために、がいしが介装されている。言い換えると、き電線はがいしを介して腕金等に支持されている。 An insulator is interposed to insulate between the feeder (overhead wire) and the brace. In other words, the feeder is supported by a brace or the like through the insulator.
がいしは適宜取換される。その際、き電線を仮支持(仮受)する必要が有る。 The insulator is replaced as appropriate. At that time, it is necessary to temporarily support (temporarily receive) the feeder.
従来、き電線がいし取替作業において、特別な工具など決められておらず、作業員が各々工夫していた。最近では、特許文献1に記載のようなき電線仮支持具(本願架線吊具に相当)が提案されている。 Conventionally, no special tools have been determined in the replacement work of feeders, and workers have devised each. Recently, there has been proposed a feeder temporary support (corresponding to the overhead wire hanging tool of the present application) as described in Patent Document 1.
上述のとおり、き電線がいし取替作業において、特別な工具など決められておらず、作業員が各々工夫していた(一例について図4に関する記載にて後述)。ところで、作業手順の大略は定められており、安全性については充分に検討されている。 As described above, no special tool or the like has been determined in the feeder replacement work, and the workers have devised each (an example will be described later with reference to FIG. 4). By the way, the outline of the work procedure has been determined, and the safety has been sufficiently studied.
しかしながら、き電線がいし取替作業は高所作業であり重大事故の一因ともなり得るので、安全性についてより一層検討することが好ましい。 However, the feeder replacement work is a high-place work and may contribute to a serious accident, so it is preferable to further consider safety.
なお、一般的な傾向として、安全性を重視すると作業性が低下することがある。たとえば、特許文献1記載のき電線仮支持具では、腕金に固定部を嵌めこんだ後、ボルト締めし、腕金から外方に突出するように仮固定する。確実に固定されるため、安全性は向上するが、構成が複雑で、作業手間が掛かる。すなわち作業性は低下している。 Note that, as a general tendency, workability may decrease when safety is emphasized. For example, in the feeder temporary support tool described in Patent Document 1, a fixing portion is fitted into a brace, and then bolted, and temporarily fixed so as to protrude outward from the brace. Since it is securely fixed, safety is improved, but the configuration is complicated and labor is required. That is, workability is reduced.
したがって、作業性を維持または向上させながら、安全性を向上させることが重要となる。 Therefore, it is important to improve safety while maintaining or improving workability.
本考案は上記課題を解決するものであり、作業性を維持または向上させながら、安全性を向上できる架線吊具を提供することを目的とする。 This invention solves the said subject, and it aims at providing the overhead wire hanging tool which can improve safety | security, maintaining or improving workability | operativity.
上記課題を解決する本考案はビーム又は腕金に吊り下げられている架線を仮受する架線吊具である。架線吊具は、前記架線吊具をビーム又は腕金に固定する取付部と、ワイヤーを介して前記架線を吊る架線吊部とを備える。前記取付部は前記ビーム又は腕金を囲む環状を形成する。 This invention which solves the above-mentioned subject is an overhead wire suspension which receives temporarily an overhead wire suspended from a beam or a brace. The overhead wire suspension includes an attachment portion that fixes the overhead wire suspension to a beam or a bracelet, and an overhead wire suspension that suspends the overhead wire via a wire. The attachment portion forms an annular shape that surrounds the beam or the brace.
これにより、架線吊具を腕金等に脱落することなく取付けることができる。その結果安全性は向上する。作業性は維持される。 Thereby, it is possible to attach the overhead wire hanging tool to the arm metal or the like without dropping off. As a result, safety is improved. Workability is maintained.
好ましくは、前記架線吊部と連動して、前記取付部の環状は開閉可能である。 Preferably, in conjunction with the overhead wire suspension portion, the annular shape of the attachment portion can be opened and closed.
これにより、さらに安全性は向上する。 This further improves safety.
好ましくは、前記ビーム又は腕金の断面はL字型である。前記架線吊具は、L字型部材とV字型部材から形成され、前記L字型部材は、L字第1部とL字第2部とを有し、前記V字型部材は、V字第1部とV字第2部とを有し、前記L字型部材と前記V字型部材とは、L字第1部端部およびV字隅角部にて回動可能に連結され、前記L字第1部とL字第2部と前記V字第1部は環状に結合され、前記取付部を構成し、前記V字第2部は、前記架線吊部を構成する。 Preferably, the cross section of the beam or the brace is L-shaped. The overhead wire suspension is formed of an L-shaped member and a V-shaped member, the L-shaped member has an L-shaped first part and an L-shaped second part, and the V-shaped member is a V-shaped member. The L-shaped member and the V-shaped member are connected to be rotatable at the L-shaped first portion end portion and the V-shaped corner portion. The L-shaped first part, the L-shaped second part, and the V-shaped first part are coupled in a ring shape to constitute the attachment part, and the V-shaped second part constitutes the overhead wire hanging part.
これにより、取付部の環状は前記スペーサを遊びなく囲む。 Thereby, the annular shape of the mounting portion surrounds the spacer without play.
好ましくは、前記取付部がビーム又は腕金に取り付けられた状態において、前記V字第2部端部と前記L字隅角部とが略同じ高さになるように形成される。 Preferably, the V-shaped second portion end portion and the L-shaped corner portion are formed to have substantially the same height in a state where the attachment portion is attached to a beam or a brace.
これにより、腕金等のL字向きが上下反転しても適用できる。 Accordingly, the present invention can be applied even when the L-shaped direction of a brace or the like is inverted upside down.
好ましくは、前記L字型部材は、L字第1部またはL字第2部にスペーサを取付可能とするスペーサ取付部を有する。 Preferably, the L-shaped member has a spacer mounting portion that allows a spacer to be mounted on the L-shaped first portion or the L-shaped second portion.
これにより、腕金等の寸法が一回り小さくても適用できる。 Thereby, it can be applied even if the size of the arm metal is small.
本考案の架線吊具は、作業性を維持または向上させながら、安全性を向上できる。 The overhead wire hanging tool of the present invention can improve safety while maintaining or improving workability.
〜構成〜
架線仮受機構は、がいし取替作業の際、架線を仮受するのに用いられる。
~Constitution~
The overhead wire temporary receiving mechanism is used to temporarily receive the overhead wire during the insulator replacement work.
架線仮受機構は、架線吊具10(支持物側)と架線吊具20(架線側)と張線器30とを備えている。架線吊具10(支持物側)は腕金2等に取付けられる。架線吊具20(架線側)は架線4を仮受する。張線器30の両端は、架線吊具10(支持物側)と架線吊具20(架線側)とに結合されている。腕金2等の支持物は断面L字状のL型鋼であることが多い。以下詳細に説明する。 The overhead wire provisional mechanism includes an overhead wire suspension 10 (support side), an overhead wire suspension 20 (overhead side), and a wire tensioner 30. The overhead wire suspension 10 (support side) is attached to the arm metal 2 or the like. The overhead wire hanging tool 20 (the overhead wire side) provisionally receives the overhead wire 4. Both ends of the wire tensioner 30 are coupled to the overhead wire suspension 10 (support side) and the overhead wire suspension 20 (overhead side). The support such as the arm metal 2 is often L-shaped steel having an L-shaped cross section. This will be described in detail below.
図1は、架線吊具10(支持物側)の概略構成図である。図1Aは環状の開き状態を示し、図1Bは環状の閉じ状態を示す。 FIG. 1 is a schematic configuration diagram of the overhead wire suspension 10 (on the support side). FIG. 1A shows an annular open state, and FIG. 1B shows an annular closed state.
架線吊具10(支持物側)は、L字型部材11とV字型部材14とから形成される。 The overhead wire suspension 10 (support side) is formed of an L-shaped member 11 and a V-shaped member 14.
L字型部材11は2枚のL字状の平板を対向させて連結させたものである。L字型部材11は、L字の鉛直方向に相当するL字第1部12と、L字の水平方向に相当するL字第2部13とを有する。なお、図示では、L字が上下反転かつ左右反転しているが、便宜的にL字状とする。 The L-shaped member 11 is formed by connecting two L-shaped flat plates facing each other. The L-shaped member 11 has an L-shaped first portion 12 corresponding to the L-shaped vertical direction and an L-shaped second portion 13 corresponding to the L-shaped horizontal direction. In the drawing, the L-shape is inverted upside down and left-right inverted, but for the sake of convenience, it is L-shaped.
L字第1部12の端部には孔が設けられている。また、L字第2部13の端部にも孔が設けられている。 The end of the L-shaped first part 12 is provided with a hole. Also, a hole is provided in the end of the L-shaped second portion 13.
V字型部材14は、V字一半体に相当するV字第1部15とV字別半体に相当するV字第2部16とを有する。V字第1部15とV字第2部16とは、V字隅角部17にて結合し、V字を形成する。V字第1部15の端部には孔が設けられている。V字第2部16の端部には孔が設けられている。V字隅角部17にも孔が設けられている。V字第2部16の端部は、蛇が鎌首をもたげた様な形状をしている。 The V-shaped member 14 has a V-shaped first portion 15 corresponding to a V-shaped half and a V-shaped second portion 16 corresponding to a V-shaped separate half. The V-shaped first portion 15 and the V-shaped second portion 16 are joined at a V-shaped corner portion 17 to form a V-shape. A hole is provided at the end of the V-shaped first portion 15. A hole is provided at the end of the V-shaped second portion 16. The V-shaped corner portion 17 is also provided with a hole. The end of the V-shaped second portion 16 is shaped like a snake with a sickle neck.
L字第1部12端部の孔およびV字隅角部17の孔には、ボルトが挿通され、ナットにより絞められている。すなわち、L字型部材11とV字型部材14とは、L字第1部12端部およびV字隅角部17にて回動可能に連結される。 Bolts are inserted through the holes at the ends of the L-shaped first portion 12 and the V-shaped corner portions 17 and are tightened by nuts. In other words, the L-shaped member 11 and the V-shaped member 14 are connected so as to be rotatable at the end portion of the L-shaped first portion 12 and the V-shaped corner portion 17.
L字第2部13の端部とV字第1部15端部とが離れた位置にある場合、三角環状18は開かれた状態にある(図1A参照)。 When the end portion of the L-shaped second portion 13 and the end portion of the V-shaped first portion 15 are separated, the triangular ring 18 is in an open state (see FIG. 1A).
一方、回動により、L字第2部13の端部とV字第1部15端部とが一致し、L字第2部13端部の孔およびV字第1部15端部の孔に、ボルトが挿通され、ナットにより絞められると、L字第1部12とL字第2部13とV字第1部15とは閉じられた三角環状18を形成する(図1B参照)。 On the other hand, by rotation, the end of the L-shaped second portion 13 and the end of the V-shaped first portion 15 coincide with each other, and the hole of the L-shaped second portion 13 end and the hole of the V-shaped first portion 15 end When the bolt is inserted and tightened by the nut, the L-shaped first portion 12, the L-shaped second portion 13 and the V-shaped first portion 15 form a closed triangular ring 18 (see FIG. 1B).
三角環状18の内縁は、腕金2の断面L字状に相当する。すなわち、三角環状18は腕金2(図3参照)をほぼ遊びなく囲み、取付部18を構成する。 The inner edge of the triangular ring 18 corresponds to the L-shaped cross section of the arm metal 2. That is, the triangular ring 18 surrounds the arm metal 2 (see FIG. 3) almost without play and constitutes the mounting portion 18.
また、V字第2部16は図示時計回り(おおよそ12時→2時)に回動し、V字第2部16は架線吊部19を構成する。V字第2部16端部の孔は張線器30との係合孔である。 Further, the V-shaped second portion 16 rotates clockwise as shown in the drawing (approximately 12: 00 → 2 o'clock), and the V-shaped second portion 16 constitutes an overhead wire suspension portion 19. The hole at the end of the V-shaped second portion 16 is an engagement hole with the wire tensioner 30.
図2は、架線吊具20(架線側)の概略構成図である。 FIG. 2 is a schematic configuration diagram of the overhead wire hanging tool 20 (the overhead wire side).
架線吊具20(架線側)は、フック本体21と蓋22とから形成される。フック本体21は、架線4を仮受可能なようにやや幅広とする。蓋22は、フック本体21の開口を塞ぎ、架線4が脱落するのを防止する。フック本体21の端部には、張線器30との係合孔が設けられている。 The overhead wire hanging tool 20 (the overhead wire side) is formed of a hook body 21 and a lid 22. The hook body 21 is slightly wide so that the overhead wire 4 can be provisionally received. The lid 22 closes the opening of the hook body 21 and prevents the overhead wire 4 from falling off. At the end of the hook body 21, an engagement hole with the wire tensioner 30 is provided.
張線器30(図3参照)は、ワイヤーの両端にフックを有する。レバー操作によりワイヤー長さを調整すると、ワイヤーに張力が作用する。 The wire tensioner 30 (see FIG. 3) has hooks at both ends of the wire. When the wire length is adjusted by lever operation, tension acts on the wire.
〜動作〜
図3は、がいし取替作業に係る動作について説明する図である。
~ Operation ~
FIG. 3 is a diagram for explaining an operation related to the insulator replacement work.
支柱1には水平方向に伸びる腕金2(またはビーム)が設けられる。腕金2等の支持物は断面L字状のL型鋼であることが多い。例えば、L型鋼の幅寸法および高さ寸法は65mmまたは75mmである。図示では、L字が上下反転するように設置されている。 The support 1 is provided with a brace 2 (or beam) extending in the horizontal direction. The support such as the arm metal 2 is often L-shaped steel having an L-shaped cross section. For example, the width dimension and the height dimension of L-shaped steel are 65 mm or 75 mm. In the drawing, the L-shape is installed so as to be turned upside down.
腕金2にはがいし3を介して架線4が吊支持されている。したがって、がいしには架線4の自重が作用している。したがって、以下のように架線4を仮受する。 An overhead wire 4 is suspended and supported by a brace 2 via a insulator 3. Therefore, the weight of the overhead wire 4 acts on the insulator. Therefore, the overhead wire 4 is provisionally received as follows.
取付部18が腕金2を囲むように、架線吊具10(支持物側)を腕金2に取付ける。同時に架線吊部19も形成される。 The overhead wire suspender 10 (supporting object side) is attached to the arm metal 2 so that the attachment portion 18 surrounds the arm metal 2. At the same time, the overhead wire suspension 19 is also formed.
架線吊部19に張線器30を取り付けるとともに、架線吊具20(架線側)に架線4を設置し、架線吊具20(架線側)に張線器30を取り付ける。これにより準備が完了する(図3A参照)。 The wire feeder 30 is attached to the overhead wire suspension portion 19, the overhead wire 4 is installed on the overhead wire suspension 20 (overhead wire side), and the wire feeder 30 is attached to the overhead wire suspension 20 (overhead wire side). This completes the preparation (see FIG. 3A).
レバーを操作して張線器30を絞め、架線4を引き上げると、架線4は架線吊具20(架線側)に仮受される。架線4の自重は架線吊部19を下方に引っ張るように作用する。その結果、取付部18はより確実に腕金2を締め付ける。 When the tensioner 30 is tightened by operating the lever and the overhead wire 4 is pulled up, the overhead wire 4 is provisionally received by the overhead wire hanging tool 20 (the overhead wire side). The own weight of the overhead wire 4 acts to pull the overhead wire suspension portion 19 downward. As a result, the attachment portion 18 tightens the arm metal 2 more reliably.
一方で、がいし3に作用していた力は解放される。これにより、がいし3は取換可能になる(図3B参照)。 On the other hand, the force acting on the insulator 3 is released. As a result, the insulator 3 can be replaced (see FIG. 3B).
がいし3の取換を行なった後、張線器30を緩め、新設されたがいしに架線4を支持させる。架線吊具20(架線側)から架線4を取り外し、張線器30を架線吊具10(支持物側)および架線吊具20(架線側)から取り外す。 After the insulator 3 is replaced, the wire tensioner 30 is loosened, and the overhead wire 4 is supported by the newly installed insulator. The overhead wire 4 is removed from the overhead wire hanging tool 20 (the overhead wire side), and the wire tensioner 30 is removed from the overhead wire suspension tool 10 (the support side) and the overhead wire hanging tool 20 (the overhead wire side).
このとき、架線吊部19は架線4の自重から解放されているため、取付部18による腕金2締め付けも解放されている。これにより、架線吊具10(支持物側)を腕金2から容易に取り外すことができる。 At this time, since the overhead wire suspension portion 19 is released from the own weight of the overhead wire 4, the arm metal 2 tightening by the attachment portion 18 is also released. Thereby, the overhead wire hanging tool 10 (support object side) can be easily removed from the arm bracket 2.
〜効果〜
従来技術と比較することにより、本実施形態の効果について説明する。
~effect~
The effect of this embodiment will be described by comparing with the prior art.
従来、がいし取替作業において、特別な工具など決められておらず、作業員が各々工夫していた。 Conventionally, in the insulator replacement work, no special tools have been determined, and workers have devised each.
図4は、従来技術の一例を示す概略構成および作業説明図である。 FIG. 4 is a schematic configuration and an operation explanatory diagram showing an example of the prior art.
従来技術の架線仮受機構は、架線吊具110(支持物側)と架線吊具120(架線側)と張線器30とを備えている。架線吊具110(支持物側)は腕金2等に取付けられる。架線吊具120(架線側)は架線4を仮受する。張線器30は本実施形態と共通である。 The prior art overhead wire receiving mechanism includes an overhead wire suspension 110 (support side), an overhead wire suspension 120 (overhead side), and a tensioner 30. The overhead wire hanging tool 110 (support side) is attached to the arm bracket 2 or the like. The overhead wire hanging tool 120 (the overhead wire side) provisionally receives the overhead wire 4. The stringer 30 is common to the present embodiment.
架線吊具110(支持物側)は、棒状部材であり、一端部にフックが設けられ、他端部に係合孔が設けられている。架線吊具120(架線側)は、一部開放された三角環状部材であり、頂部に係合孔が設けられている。張線器30の両フックは、両係合孔にそれぞれ取り付けられている。 The overhead wire hanging tool 110 (support side) is a rod-shaped member, and is provided with a hook at one end and an engagement hole at the other end. The overhead wire suspension 120 (the overhead wire side) is a triangular ring member that is partially opened, and has an engagement hole at the top. Both hooks of the wire tensioner 30 are respectively attached to both engagement holes.
架線吊具110(支持物側)は水平に腕金2に仮置きされるともに、架線吊具110(支持物側)のフックは腕金2に引っ掛けられる。 The overhead wire suspension 110 (support side) is temporarily placed on the arm metal 2 horizontally, and the hook of the overhead wire suspension 110 (support side) is hooked on the arm metal 2.
張線器30の操作により架線4を仮受する動作は、本実施形態と共通である。 The operation of temporarily receiving the overhead wire 4 by operating the wire feeder 30 is the same as that of the present embodiment.
従来技術においても安全性について検討されているが、以下の懸念がある。 Although safety has been studied in the prior art, there are the following concerns.
架線吊具110(支持物側)の腕金2への取付は、フックによる係止のみであるため、万が一の場合、外れるおそれがないわけではない。 Since the attachment of the overhead wire hanging tool 110 (support side) to the arm metal 2 is only locking by a hook, in the unlikely event, there is no risk of detachment.
特に、仮受時にはフック周辺に図示時計回りの大きなモーメントが発生する。想定以上の力が作用した場合、フックが降伏するおそれもある。 In particular, a large moment in the clockwise direction in the figure is generated around the hook during provisional reception. If more force than expected is applied, the hook may yield.
また、フックを腕金2に係止する際に、架線吊具110(支持物側)の重心が腕金2上から外れて、不安定になるため、より慎重な作業が求められる。その結果、作業性が低下する。 In addition, when the hook is locked to the arm metal 2, the center of gravity of the overhead wire hanging tool 110 (the support side) is detached from the arm metal 2 and becomes unstable, so that more careful work is required. As a result, workability is reduced.
なお、一般的な傾向として、安全性を重視すると作業性が低下することがある。 Note that, as a general tendency, workability may decrease when safety is emphasized.
これに対し、本実施形態では、三角環状18が腕金2をほぼ遊びなく囲み、脱落を防止している。 On the other hand, in the present embodiment, the triangular ring 18 surrounds the arm metal 2 almost without play, thereby preventing the falling off.
さらに、仮受時には、三角環状18はより確実に腕金2を締め付ける。仮受後には解放され、容易に取外しできる。 Furthermore, at the time of provisional reception, the triangular ring 18 tightens the arm 2 more securely. It is released after provisional reception and can be easily removed.
これらの安全性向上のために面倒な作業は必要なく、作業性は維持される。 There is no need for troublesome work to improve safety, and workability is maintained.
一方で、架線吊具10(支持物側)を腕金2上に仮置きするときは、V字第2部16は上方に伸びた状態にある(図1A参照)。これにより、架線吊具10(支持物側)の重心はほぼ腕金2上にあり、安定な状態である。その結果、安全性が向上するとともに、作業性も向上する。 On the other hand, when the overhead wire suspension 10 (support side) is temporarily placed on the brace 2, the V-shaped second portion 16 extends upward (see FIG. 1A). As a result, the center of gravity of the overhead wire suspension 10 (on the support side) is substantially on the arm metal 2 and is in a stable state. As a result, safety is improved and workability is also improved.
以上のように、本実施形態は、作業性を維持または向上させながら、安全性を向上できる。 As described above, this embodiment can improve safety while maintaining or improving workability.
〜変形使用例〜
本実施形態の取付部18が腕金等に取り付けられた状態において、V字第2部16端部とL字隅角部(L字第1部12とL字第2部13との交点)とが略同じ高さになるように形成されている(図1B参照)。
~ Example of deformation ~
In the state in which the attachment portion 18 of this embodiment is attached to a brace or the like, the end portion of the V-shaped second portion 16 and the L-shaped corner portion (intersection of the L-shaped first portion 12 and the L-shaped second portion 13) Are formed to have substantially the same height (see FIG. 1B).
ところで、上記では、腕金2等の支持物は断面L字状のL型鋼である、L字が上下反転するように設置されていることを前提に説明している。 By the way, the above description is based on the assumption that the support such as the arm metal 2 is an L-shaped steel having an L-shaped cross section and is installed so that the L-shape is inverted upside down.
しかしながら、L字が順方向となるように腕金2が設置される場合もある。このような場合も、架線吊具10(支持物側)を上下反転させることで、取付部18が腕金2を囲むように、架線吊具10(支持物側)を腕金2に取付けることができる。 However, the brace 2 may be installed so that the L-shape is in the forward direction. Also in such a case, the overhead wire suspension 10 (support side) is attached to the arm metal 2 so that the attachment portion 18 surrounds the arm metal 2 by turning the overhead wire suspension 10 (support side) upside down. Can do.
その際、架線吊部19は上記同様適切な位置となる(図5参照)。 At that time, the overhead wire suspension portion 19 is in an appropriate position as described above (see FIG. 5).
他の使用例について説明する。 Another usage example will be described.
腕金2等の支持物は断面L字状のL型鋼であることが多い。例えば、L型鋼の幅寸法および高さ寸法は65mmまたは75mmである。 The support such as the arm metal 2 is often L-shaped steel having an L-shaped cross section. For example, the width dimension and the height dimension of L-shaped steel are 65 mm or 75 mm.
一方で、架線吊具10(支持物側)において、三角環状18の内縁は、腕金2の断面L字状に相当する。これにより、三角環状18は腕金2をほぼ遊びなく囲む。 On the other hand, in the overhead wire suspension 10 (on the support side), the inner edge of the triangular ring 18 corresponds to the L-shaped cross section of the arm metal 2. Thereby, the triangular ring 18 surrounds the arm metal 2 almost without play.
例えば、L型鋼の幅寸法および高さ寸法が75mmである場合、三角環状18の内縁がL型鋼を内接するように架線吊具10(支持物側)の寸法を設計する。 For example, when the width dimension and height dimension of the L-shaped steel are 75 mm, the dimensions of the overhead wire suspension 10 (support side) are designed so that the inner edge of the triangular ring 18 inscribes the L-shaped steel.
しかしながら、例えば、L型鋼の幅寸法および高さ寸法が65mmである場合、三角環状18の内縁より一回り小さくなり、遊びが発生する・ However, for example, when the width and height of the L-shaped steel are 65 mm, the size becomes slightly smaller than the inner edge of the triangular ring 18 and play occurs.
遊びが発生する場合、L字第1部12またはL字第2部13に、スペーサ9を装着する(図6参照)。L字第1部12中央またはL字第2部13中央に孔が設けられている。スペーサ9にも孔が設けられている。両孔にボルトを挿通し、ナット締めする。 When play occurs, the spacer 9 is attached to the L-shaped first part 12 or the L-shaped second part 13 (see FIG. 6). A hole is provided in the center of the L-shaped first portion 12 or the center of the L-shaped second portion 13. The spacer 9 is also provided with a hole. Insert bolts into both holes and tighten the nuts.
これにより、L型鋼の幅寸法および高さ寸法が65mmである場合でも、L型鋼の幅寸法および高さ寸法が75mmに対応する架線吊具10(支持物側)を適用することができる。 Thereby, even when the width dimension and height dimension of L-shaped steel are 65 mm, the overhead wire suspension 10 (support side) corresponding to the width dimension and height dimension of L-shaped steel of 75 mm can be applied.
以上のように、基本使用例と異なった使用方法もでき、汎用性が高い。 As described above, the usage method can be different from the basic usage example, and the versatility is high.
