Description

この発明は、電気鉄道線路のトロリ線のような架空線の張力を一定に維持するための滑車式のテンションバランサに関するものである。   The present invention relates to a pulley-type tension balancer for maintaining a constant tension of an overhead wire such as a trolley wire of an electric railway track.

切断等に伴う架空線の流れを阻止する機構を備えたテンションバランサが特許文献１に記載されている。この滑車式テンションバランサは、図５に示すように、基端において支柱Ｐに垂直方向に旋回自在に枢支された腕金１と、この腕金１の先端に軸支された滑車２と、この滑車２に一端側が巻き止められ他端がトロリ線等の架空線に連結された牽引ロープ３と、滑車２に一端が巻き止められ他端に重錘Ｗが固着された吊り下げロープ４と、腕金１の下方において基端が支柱Ｐに垂直方向に旋回自在に枢支され先端が滑車２の外周付近に配置され中間が補助リンク５により腕金１の中間に連結されたストッパアーム６とを具備する。特許文献１には記載されていないが、一般に重錘Ｗは、支柱Ｐに支持された振れ止め装置７により垂直昇降自在に支持される。振れ止め装置７は、支柱Ｐに支持された上下一対の振れ止めブラケット８，９間に振れ止めロッド１０を張って構成される。上部の振れ止めブラケット８は、テンションバー１１で支柱Ｐに支持される。しかして、腕金１は第１のバンド金具１２で、ストッパアーム６とテンションバー１１は第２のバンド金具１３で、振れ止めブラケット８は第３のバンド金具１４でそれぞれ支柱Ｐに支持される。
この滑車式テンションバランサは、吊り下げロープ４、滑車１、牽引ロープ３を介して重錘Ｗにより常時架空線に所定の張力を付与する。架空線が切断等で解放されて、滑車２がわずかに下降すると、ストッパアーム６の先端が滑車２の外周の歯２ａに噛み合って、滑車２の下降と回転を止める。
ストッパアーム６の先端と滑車２との間隔は、気温の変化、あるいは架空線の線種変更に伴う張力アップ等により変化する。この間隔が広すぎれば、架空線切断時に滑車２を止めることができず、逆に狭すぎれば滑車２とストッパアーム６が干渉してバランサとしての機能を果たすことができなくなる。そこで、バランサを常時適正に機能させるために、頻繁な間隔調整が必要になる。この間隔調整は、ストッパアーム６の支持位置を上下に調整することにより行われるが、ストッパアーム６とテンションバー１１とが共通のバンド金具１３に連結されているために、振れ止め装置７も同時に移動させなければならず、多くの手数と労力を要する難作業となるという問題点がある。
実公昭３２−１５２０８号公報 Patent Document 1 discloses a tension balancer having a mechanism for preventing the flow of an overhead wire accompanying cutting or the like. As shown in FIG. 5, the pulley-type tension balancer includes a brace 1 pivotally supported at the base end so as to be pivotable in a vertical direction to a support P, a pulley 2 pivotally supported at the tip of the brace 1, A pulling rope 3 having one end wound around the pulley 2 and the other end connected to an overhead wire such as a trolley wire, and a suspension rope 4 having one end wound around the pulley 2 and a weight W fixed to the other end A stopper arm 6 having a base end pivotally supported by the support column P so as to be pivotable in the vertical direction below the arm metal 1, a distal end disposed near the outer periphery of the pulley 2, and a middle portion connected to the middle of the arm metal 1 by an auxiliary link 5. It comprises. Although not described in Patent Document 1, generally, the weight W is supported by a steady rest device 7 supported by a support P so as to be vertically movable up and down. The steady-rest device 7 is configured by stretching a steady-rest rod 10 between a pair of upper and lower steady-rest brackets 8 and 9 supported by a support P. The upper steady rest bracket 8 is supported on the support column P by a tension bar 11. Thus, the arm 1 is supported by the first band metal 12, the stopper arm 6 and the tension bar 11 are supported by the second band metal 13, and the steady bracket 8 is supported by the column P by the third band metal 14. .
This pulley-type tension balancer always applies a predetermined tension to the overhead wire by the weight W via the hanging rope 4, the pulley 1, and the tow rope 3. When the overhead wire is released by cutting or the like and the pulley 2 is slightly lowered, the tip of the stopper arm 6 is engaged with the teeth 2a on the outer periphery of the pulley 2 to stop the lowering and rotation of the pulley 2.
The distance between the tip of the stopper arm 6 and the pulley 2 changes due to a change in temperature or an increase in tension accompanying a change in the line type of the overhead wire. If the distance is too wide, the pulley 2 cannot be stopped when the overhead line is cut. Conversely, if the distance is too narrow, the pulley 2 and the stopper arm 6 interfere with each other and cannot function as a balancer. Therefore, frequent interval adjustments are necessary in order for the balancer to function properly at all times. This interval adjustment is performed by adjusting the support position of the stopper arm 6 up and down. However, since the stopper arm 6 and the tension bar 11 are connected to the common band metal fitting 13, the steadying device 7 is also simultaneously used. There is a problem that it has to be moved and is a difficult task requiring a lot of work and labor.
Japanese Utility Model Publication No. 32-15208

この発明は、従来の滑車式テンションバランサにおける上記のような問題点を解決し、ストッパアームの支持位置の調整を振れ止め装置と無関係に、簡単に行うことができる滑車式のテンションバランサを提供することを課題としている。   The present invention provides a pulley-type tension balancer that can solve the above-described problems in a conventional pulley-type tension balancer and that can easily adjust the support position of the stopper arm independently of the steady rest device. It is an issue.

請求項１に記載の発明においては、上記課題を解決するため、腕金１の基端を支柱Ｐに固定された第１のバンド金具１２に枢支し、ストッパアーム６の基端を支柱Ｐに固定された第２のバンド金具１３に枢支し、上部の振れ止めブラケット８の基端を支柱に固定された第３のバンド金具１４に枢支し、上部の振れ止めブラケット８の中間部に下端が枢支されたテンションバー１１の上端を支柱に固定された第４のバンド金具１５に枢支することにより、振れ止め装置７と独立してストッパアーム６の支柱Ｐに対する支持位置を上下方向に調整可能とした。

By pivotally supporting the upper end of the tension bar 11 whose lower end is pivotally supported by a fourth band metal fitting 15 fixed to the column, the support position of the stopper arm 6 with respect to the column P is moved up and down independently of the steadying device 7. Adjustable to the direction.
In the invention according to claim 2, the fourth band metal fitting 15 is attached between the first band metal fitting 12 and the second band metal fitting 13, so that the tension bar 11 does not interfere with the stopper arm 6. The tension bar 11 is provided with a pair of legs 11a divided into two forks.

この発明においては、振れ止めブラケット８の基端を第３のバンド金具１４に支持し、またテンションバー１１の上端をバンド金具１４とは別の第４のバンド金具１５に枢支したため、ストッパアーム６の支柱Ｐに対する支持位置を単独で簡単に上下方向に移動調整できるようになった。   In the present invention, since the base end of the steady rest bracket 8 is supported by the third band fitting 14 and the upper end of the tension bar 11 is pivotally supported by the fourth band fitting 15 different from the band fitting 14, the stopper arm It is now possible to easily move and adjust the support position for the six struts P independently in the vertical direction.

図面を参照してこの発明の実施の形態を説明する。図１は滑車式テンションバランサの正面図、図２は同平面図、図３は要部の正面図、図４は図３におけるIV−IV矢視図である。
腕金１は、基端において支柱Ｐに垂直方向に旋回自在に枢支される。腕金１の先端には滑車２が軸支される。この滑車２の小径部には、トロリ線等の架空線に連結された牽引ロープ３の一端側が巻き止められる。滑車２の大径部には、重錘Ｗが固着された吊り下げロープ４の上端部が巻き止められる。滑車２の大径部の外周には、多数の歯が設けられている。腕金１の下方には、ストッパアーム６が設けられ、その基端は支柱Ｐに垂直方向に旋回自在に枢支される。ストッパアーム６の先端は、滑車２の外周付近に配置され、その中間（図において先端部付近）は、補助リンク５により腕金１の中間に連結される。重錘Ｗは、支柱Ｐに支持された振れ止め装置７により垂直昇降自在に支持される。振れ止め装置７は、支柱Ｐに支持された上下一対の振れ止めブラケット８，９間に振れ止めロッド１０を張って構成される。上部の振れ止めブラケット８は、テンションバー１１で支柱Ｐに支持される。 Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pulley-type tension balancer, FIG. 2 is a plan view thereof, FIG. 3 is a front view of a main part, and FIG. 4 is a view taken along arrows IV-IV in FIG.
The arm 1 is pivotally supported at the proximal end so as to be pivotable in the vertical direction on the support P. A pulley 2 is pivotally supported at the tip of the arm 1. One end side of the pulling rope 3 connected to an overhead wire such as a trolley wire is fastened to the small diameter portion of the pulley 2. The upper end portion of the suspension rope 4 to which the weight W is fixed is fastened to the large diameter portion of the pulley 2. A large number of teeth are provided on the outer periphery of the large-diameter portion of the pulley 2. A stopper arm 6 is provided below the arm metal 1 and its base end is pivotally supported by the column P so as to be pivotable in the vertical direction. The tip of the stopper arm 6 is disposed near the outer periphery of the pulley 2, and the middle (near the tip in the drawing) is connected to the middle of the arm 1 by an auxiliary link 5. The weight W is supported by the steady rest device 7 supported by the support column P so as to be vertically movable up and down. The steady-rest device 7 is configured by stretching a steady-rest rod 10 between a pair of upper and lower steady-rest brackets 8 and 9 supported by a support P. The upper steady rest bracket 8 is supported on the support column P by a tension bar 11.

しかして、腕金１は第１のバンド金具１２で、ストッパアーム６は第２のバンド金具１３で、振れ止めブラケット８は第３のバンド金具１４で、テンションバー１１は第４のバンド金具１５でそれぞれ支柱Ｐに支持される。第４のバンド金具１５は、第１のバンド金具１２と第２のバンド金具１３との間に取り付けられる。テンションバー１１が、ストッパアーム６に干渉しないように、テンションバー１１には、二股に分かれた一対の脚１１ａが設けられる。   The arm 1 is the first band metal 12, the stopper arm 6 is the second band metal 13, the steady bracket 8 is the third band metal 14, and the tension bar 11 is the fourth band metal 15.

In order to prevent the tension bar 11 from interfering with the stopper arm 6, the tension bar 11 is provided with a pair of legs 11a divided into two forks.

この滑車式テンションバランサは、吊り下げロープ４、滑車１、牽引ロープ３を介して重錘Ｗにより常時架空線に所定の張力を付与する。架空線が切断等で解放されて、滑車２がわずかに下降すると、ストッパアーム６の先端が滑車２の外周の歯２ａに噛み合って、滑車２の下降と回転を止める。振れ止めブラケット８の基端を第３のバンド金具１４に支持し、またテンションバー１１の上端をバンド金具１４とは別の第４のバンド金具１５に枢支したため、ストッパアーム６の支柱Ｐに対する支持位置を単独で上下方向に移動調整できる。したがって、滑車２の上下位置に変更が生じた場合に、ストッパアーム６の先端の位置をこれに合わせて調整する作業を簡単に行うことができる。   This pulley-type tension balancer always applies a predetermined tension to the overhead wire by the weight W via the hanging rope 4, the pulley 1, and the tow rope 3. When the overhead wire is released by cutting or the like and the pulley 2 is slightly lowered, the tip of the stopper arm 6 is engaged with the teeth 2a on the outer periphery of the pulley 2 to stop the lowering and rotation of the pulley 2. Since the base end of the steady rest bracket 8 is supported by the third band metal fitting 14 and the upper end of the tension bar 11 is pivotally supported by a fourth band metal fitting 15 different from the band metal fitting 14, The support position can be moved and adjusted independently. Therefore, when the vertical position of the pulley 2 is changed, the operation of adjusting the position of the tip of the stopper arm 6 according to the change can be easily performed.

この発明は、電気鉄道線路のトロリ線のような架空線の張力を一定に維持するための滑車式のテンションバランサに利用される。   The present invention is used for a pulley-type tension balancer for maintaining a constant tension of an overhead wire such as a trolley wire of an electric railway track.
