Description

本発明は、線ばねの弾性力によりレールのフランジ部をまくらぎに固定するレール締結装置の線ばね抜け止め手段に関する。さらに詳しくは、レール締結装置において、レール締結装置から線ばねが抜け出ること、レール締結装置から抜けた線ばねがレール締結装置から飛散、落下等することを止めるためのレール締結装置の線ばね抜け止め手段に関する。 The present invention relates to a wire spring retaining means for a rail fastening device that fixes a flange portion of a rail to a sleeper by the elastic force of the wire spring. More specifically, in a rail fastening device, the wire spring of the rail fastening device for preventing the wire spring from coming out of the rail fastening device and the wire spring coming out of the rail fastening device from scattering, dropping, etc. from the rail fastening device. It relates to means.

鉄道用の軌道は、道床の上に敷設されたまくらぎと、まくらぎの上に乗せられたレールと、このレールをまくらぎに締結するためのレール締結装置で構成される。近年、クリップ状に屈曲形成された線ばねを利用し、その線ばねの弾性力でレールのフランジ部を押さえるタイプのレール締結装置が提案されている（例えば、特許文献１参照）。 The railroad track includes a sleeper laid on the roadbed, a rail placed on the sleeper, and a rail fastening device for fastening the rail to the sleeper. In recent years, a rail fastening device of a type that uses a wire spring bent in a clip shape and presses the flange portion of the rail with the elastic force of the wire spring has been proposed (for example, see Patent Document 1).

この線ばねを利用したレール締結装置は、ばね支持体と線ばねにより構成されている。ばね支持体は、レールのフランジ部の両側でまくらぎに埋設される脚部を備えており、レール長手方向に延びる貫通孔が形成されている。線ばねはクリップ状に形成され、それぞれが実質的に平行に延びる挿入部、支持部及びフランジ押さえ部により構成される。 The rail fastening device using this wire spring is composed of a spring support and a wire spring. The spring support body includes leg portions embedded in sleepers on both sides of the flange portion of the rail, and a through hole extending in the rail longitudinal direction is formed. The wire spring is formed in a clip shape, and includes an insertion portion, a support portion, and a flange pressing portion, each extending substantially in parallel.

挿入部は、ばね支持体の貫通孔に挿入される部分である。支持部は、ばね支持体のばね受け面に当接する部分である。フランジ押さえ部は、レールのフランジ部をまくらぎに向かって付勢する部分である。挿入部は、ばね支持体の貫通孔への挿入側において第１アーム部で支持部と連続している。支持部は、挿入部と連続する側と反対側の端部において、第２アーム部でフランジ押さえ部に連続している。線ばねの挿入部をばね支持体の貫通孔に挿入し、線ばねのフランジ押さえ部をレールのフランジ部に当接させると、線ばねがレールを弾性力により押え付けることで、レールがまくらぎに固定される。 An insertion part is a part inserted in the through-hole of a spring support body. A support part is a part contact | abutted to the spring receiving surface of a spring support body. The flange pressing portion is a portion that biases the flange portion of the rail toward the sleeper. The insertion portion is continuous with the support portion at the first arm portion on the insertion side to the through hole of the spring support. The support portion is continuous with the flange pressing portion at the second arm portion at the end opposite to the side continuous with the insertion portion. When the wire spring insertion part is inserted into the through hole of the spring support and the flange holding part of the wire spring is brought into contact with the flange part of the rail, the wire spring presses the rail with elastic force, so that the rail becomes sleepy. Fixed to.

前記特許文献１のレール締結装置は、線ばねが貫通孔に挿入される方向には第１アーム部があるために抜け出ることはない。しかし、線ばねは摩擦力でばね支持体に保持されているだけであるから、摩擦力を越えた力が、線ばね挿入方向と逆方向に線ばねに作用したときには、線ばねはばね支持体から外れることになる。 The rail fastening device of Patent Document 1 does not come out because the first arm portion is in the direction in which the wire spring is inserted into the through hole. However, since the wire spring is only held on the spring support by the frictional force, when the force exceeding the frictional force acts on the wire spring in the direction opposite to the direction in which the wire spring is inserted, the wire spring is not supported by the spring support. It will come off.

線ばねがばね支持体から抜け出ると、レールを適正な位置に保持できなくなる。また、前記特許文献１のレール締結装置を橋梁上や天井走行クレーンで用いるときには、レールの下方に人の往来が有り、線ばねの落下による二次災害を誘発する恐れがある。そのため、線ばねが抜け出ることを確実に防止することが求められる。 When the wire spring comes out of the spring support, the rail cannot be held in the proper position. Further, when the rail fastening device of Patent Document 1 is used on a bridge or an overhead traveling crane, there is a possibility that a person will come and go under the rail and induce a secondary disaster due to the fall of the wire spring. Therefore, it is required to reliably prevent the wire spring from coming out.

特許文献２の線ばね抜け止め具は、貫通孔の両端から突出する軸部と、軸部の一端に固着されて第１アーム部の背面に当接する係留部と、軸部の他端に着脱可能でばね支持体の端面に当接するストッパで構成されている。従って、レール締結装置自体に抜け止めのための特別の加工を施す必要がなく、また、特定の治具を要しないため、作業現場で容易に着脱することができる。しかし、特許文献２の線ばね抜け止め具は、金属製の数点の部品で構成され、複雑な形状を有しているため、部品製造コスト及び部品管理コストが高価になる問題があった。 The wire spring retainer of Patent Document 2 includes a shaft portion protruding from both ends of the through hole, a mooring portion fixed to one end of the shaft portion and abutting against the back surface of the first arm portion, and attached to and detached from the other end of the shaft portion. The stopper is configured to be capable of abutting against the end face of the spring support. Accordingly, it is not necessary to perform special processing for retaining the rail fastening device itself, and a specific jig is not required, so that it can be easily attached and detached at the work site. However, the wire spring retainer of Patent Document 2 is composed of several metal parts and has a complicated shape, and thus there is a problem that the part manufacturing cost and the part management cost become expensive.

なお、本発明でいう「線ばね抜け止め」とは、単にレール締結装置から線ばねが抜け出るのを止める（防止する）ことを意味するものでなく、線ばねがレール締結装置から抜けた時、線ばねがレール締結装置から飛散、落下等することを止める（防止する）ことも含んだものであることを意味している。 The term “wire spring retaining” in the present invention does not simply mean stopping (preventing) the wire spring from coming out of the rail fastening device, but when the wire spring comes out of the rail fastening device, This means that the wire spring includes stopping (preventing) scattering, dropping, and the like from the rail fastening device.

鉄道用の軌道は、例えば、コンクリート製のまくらぎ１０と、このまくらぎ１０の上面にゴムパッド１１を介して敷設されるレール１２と、レール１２をまくらぎ１０に固定するレール締結装置１４とを有している。図１及び図２に示すように、レール締結装置１４は、ばね支持体１６と線ばね１８とを有している。さらに、レール締結装置１４はインシュレータ２０を備え、インシュレータ２０を介して、レール１２下部のフランジ部２２を押えている。インシュレータ２０は、省略することが可能である。 The railroad track includes, for example, a concrete sleeper 10, a rail 12 laid on the upper surface of the sleeper 10 via a rubber pad 11, and a rail fastening device 14 that fixes the rail 12 to the sleeper 10. Have. As shown in FIGS. 1 and 2, the rail fastening device 14 includes a spring support 16 and a wire spring 18. Furthermore, the rail fastening device 14 includes an insulator 20 and presses the flange portion 22 below the rail 12 via the insulator 20. The insulator 20 can be omitted.

ばね支持体１６は、まくらぎ１０に埋設して固定される脚部２４を備えている。敷設されるレール１２のフランジ部２２の両側に脚部２４が埋設されることにより、ばね支持体１６は、レール１２の中心軸線１２Ａに対して対称な位置に配設される。ばね支持体１６は、レール１２の長手方向（図１、図３で紙面に直交する方向）に延びる貫通孔２６を備えている。線ばね１８は、全体が断面円形の鋼材を屈曲形成して製造されている。 The spring support 16 includes leg portions 24 that are embedded and fixed in the sleeper 10. By embedding the leg portions 24 on both sides of the flange portion 22 of the rail 12 to be laid, the spring support 16 is disposed at a position symmetrical with respect to the central axis 12A of the rail 12. The spring support 16 includes a through hole 26 extending in the longitudinal direction of the rail 12 (a direction orthogonal to the paper surface in FIGS. 1 and 3). The wire spring 18 is manufactured by bending a steel material having a circular cross section as a whole.

線ばね１８は、貫通孔２６に挿入可能な挿入部３２と、ばね支持体１６のショルダー部分３４のばね受け面３６に当接する支持部３８と、インシュレータ２０を介してレール１２のフランジ部２２をまくらぎ１０に向って付勢するフランジ押さえ部４０とを備えている。挿入部３２は貫通孔２６に隙間を有して挿入可能な断面形状に形成されている。挿入部３２、支持部３８及びフランジ押さえ部４０は、レール１２の長手方向に平行に延び、お互いが実質的に平行である。 The wire spring 18 has an insertion portion 32 that can be inserted into the through hole 26, a support portion 38 that abuts against a spring receiving surface 36 of the shoulder portion 34 of the spring support 16, and the flange portion 22 of the rail 12 via the insulator 20. And a flange pressing portion 40 that urges toward the sleeper 10. The insertion portion 32 is formed in a cross-sectional shape that can be inserted with a gap in the through hole 26. The insertion portion 32, the support portion 38, and the flange pressing portion 40 extend in parallel to the longitudinal direction of the rail 12, and are substantially parallel to each other.

線ばね１８は、さらに、挿入部３２と支持部３８とを連続させるＵ字状の第１アーム部４２と、第１アーム部４２の反対側で支持部３８とフランジ押さえ部４０を連続させるＵ字状の第２アーム部４４とを有する。線ばね１８を弾性変形させて、挿入部３２を貫通孔２６に挿入すると、フランジ押さえ部４０がインシュレータ２０を介してレール１２のフランジ部２２をまくらぎ１０に向って付勢する。レール締結装置１４は、線ばね１８の弾性力による摩擦力によって、レール１２をまくらぎ１０に固定する。 The wire spring 18 further includes a U-shaped first arm portion 42 that allows the insertion portion 32 and the support portion 38 to continue, and a U-shape that causes the support portion 38 and the flange pressing portion 40 to continue on the opposite side of the first arm portion 42. And a second arm portion 44 having a letter shape. When the wire spring 18 is elastically deformed and the insertion portion 32 is inserted into the through hole 26, the flange pressing portion 40 urges the flange portion 22 of the rail 12 toward the sleeper 10 via the insulator 20. The rail fastening device 14 fixes the rail 12 to the sleeper 10 by the frictional force generated by the elastic force of the wire spring 18.

図５は、本発明の第１の実施の形態の線ばね抜け止め手段５０の代表的な形態を示し、図５（ａ）は全体正面図、図５（ｂ）は第１結束バンド６０のロック部にバンド部を挿入した状態を示す拡大断面図、図５（ｃ）は第２結束バンド７０のロック部にバンド部を挿入した状態を示す拡大断面図である。本発明の第１の実施の形態の線ばね抜け止め手段５０は、図５（ａ）の右側から順に、第１結束バンド６０、連結部８０、第２結束バンド７０で構成されている。 FIG. 5 shows a typical form of the wire spring retaining means 50 according to the first embodiment of the present invention. FIG. 5 (a) is an overall front view, and FIG. 5 (b) is the first binding band 60. FIG. 5C is an enlarged cross-sectional view showing a state where the band portion is inserted into the lock portion of the second binding band 70, and FIG. The wire spring retaining means 50 according to the first embodiment of the present invention includes a first binding band 60, a connecting portion 80, and a second binding band 70 in order from the right side of FIG.

第１結束バンド６０は、ロの字形状のロック部６１と、ロック部６１を左端部として、ロック部６１から右側に延びるバンド部６２とを有する。ロック部６１は、バンド係止部６３をバンド挿通孔６４内に有する。バンド部６２は、可撓性を有し、鋸歯状の係合部６５が長手方向に連続して複数形成され、ロック部６１のバンド挿通孔６４内でバンド係止部６３に係止する。言い換えると、係合部６５は、所定の角度傾斜している傾斜面６５ａと係合面６５ｂが形成された三角形形状の部位が連続しているものである。バンド係止部６３は、一つまたは複数（この形態では３個）の三角形形状のバンド係止山部が形成されたものである。 The first binding band 60 includes a square-shaped lock portion 61 and a band portion 62 that extends to the right from the lock portion 61 with the lock portion 61 as a left end portion. The lock part 61 has a band locking part 63 in the band insertion hole 64. The band part 62 has flexibility, and a plurality of serrated engaging parts 65 are continuously formed in the longitudinal direction, and is locked to the band locking part 63 in the band insertion hole 64 of the lock part 61. In other words, the engaging portion 65 is formed by a continuous triangular portion where the inclined surface 65a inclined by a predetermined angle and the engaging surface 65b are formed. The band locking portion 63 is formed with one or a plurality (three in this embodiment) of triangular band locking peaks.

第１結束バンド６０は、図１及び図２に示すように、バンド部６２を、ばね支持体１６の貫通孔２６に挿入し、ばね支持体１６のショルダー部分３４の周囲に一回巻き付けてから、図５（ｂ）の矢印Ａ１方向からバンド挿通孔６４内に挿通する。続いて、バンド挿通孔６４から飛び出したバンド部６２の右端部を引張ると、バンド挿通孔６４内でバンド係止部６３に係合部６５が係止されるため、第１結束バンド６０を、ばね支持体１６に強固に締め付けることができる。すなわち、図５（ｂ）において、ロック部６１に対してバンド部６２を矢印Ａ１の方向に移動させようとした場合、バンド係止部６３は、係合部６５の傾斜面６５ａの傾斜に沿って、部位６３ａを支点にして係合部６５から離れる方向に弾性変形し、バンド部６２の移動を可能にする。 As shown in FIGS. 1 and 2, the first binding band 60 is formed by inserting the band portion 62 into the through hole 26 of the spring support 16 and winding it once around the shoulder portion 34 of the spring support 16. 5B is inserted into the band insertion hole 64 from the direction of the arrow A1 in FIG. Subsequently, when the right end portion of the band portion 62 jumping out from the band insertion hole 64 is pulled, the engagement portion 65 is locked to the band locking portion 63 in the band insertion hole 64, so the first binding band 60 is The spring support 16 can be firmly tightened. That is, in FIG. 5B, when the band portion 62 is moved in the direction of the arrow A1 with respect to the lock portion 61, the band locking portion 63 follows the inclination of the inclined surface 65a of the engaging portion 65. Thus, the band part 62 can be moved by elastically deforming in a direction away from the engaging part 65 with the part 63a as a fulcrum.

また、ロック部６１に対してバンド部６２を矢印Ａ２の方向に移動させようとした場合、バンド係止部６３には係合部６５の係合面６５ｂから力が作用する。すなわち、バンド係止部６３には、矢印Ａ２方向または傾斜面６５ａ側に押圧される方向に力が作用するため、バンド係止部６３と係合部６５との係止状態が解除されずバンド部６２は移動することができない。すなわち、係合部６５は鋸歯状に形成されているため、バンド部６２に矢印Ａ２方向の引っ張り力が作用しても、係合部６５の係止面６５ｂとバンド係止部６３との係止が解除されることはなく、バンド部６２が緩むことはない。 Further, when trying to move the band portion 62 in the direction of the arrow A <b> 2 with respect to the lock portion 61, a force acts on the band locking portion 63 from the engaging surface 65 b of the engaging portion 65. That is, since a force acts on the band locking portion 63 in the direction of the arrow A2 or the direction pressed toward the inclined surface 65a, the locking state between the band locking portion 63 and the engaging portion 65 is not released. The part 62 cannot move. That is, since the engaging portion 65 is formed in a sawtooth shape, the engagement between the locking surface 65b of the engaging portion 65 and the band locking portion 63 even if a tensile force in the direction of arrow A2 acts on the band portion 62. The stop is not released and the band portion 62 does not loosen.

第２結束バンド７０は、第１結束バンド６０と同様に、ロック部７１、バンド挿通孔７４、バンド係止部７３、バンド部７２、係合部７５を有し、ロック部７１を図５（ａ）の右端部として、ロック部７１から左側に延びるバンド部７２を有する。第１結束バンド６０と第２結束バンド７０は、ロック部６１とロック部７１が連結部８０によって連結されて、直線状に一体的に形成されている。 Similar to the first binding band 60, the second binding band 70 has a lock portion 71, a band insertion hole 74, a band locking portion 73, a band portion 72, and an engagement portion 75.
