【考案の詳細な説明】
本考案はクレーンやホイストなどの給電用コレクタをト
ロリー線の垂れ下がりに対して追随し、確実にコレクタ
がトロリー線に圧接し給電を行うようになしたコレクタ
の揺動角規制装置に関するものである。[Detailed description of the invention] This invention has a power supply collector such as a crane or hoist that follows the drooping of the trolley wire to ensure that the collector is in pressure contact with the trolley wire to supply power. It concerns a regulating device.
クレーン・ホイスト等はその走行方向に沿って張架した
トロリー線に走行体側に突設したコレクタを圧接し走行
体走行に際し該コレクタがトロリー線に対して摺動して
給電している。In cranes, hoists, etc., a collector protruding toward the traveling body is pressed into contact with a trolley wire stretched along the traveling direction, and when the traveling body is traveling, the collector slides against the trolley wire to supply electricity.
しかしこのトロリー線をたるみや蛇行をなくし直線状に
張架することはむつかしく、長手の使用や温度変化その
他の影響を受けてトロリー線は張架方向に対して蛇行し
たり、たゆみが生じたりする。However, it is difficult to stretch the trolley wire in a straight line without slack or meandering, and the trolley wire may meander or sag in the direction of tension due to the use of long wires, temperature changes, and other influences. .
この蛇行に対してはコレクタを二重首振式とすることに
より容易にその欠点を解消することができるがトロリー
線の垂れ下がりに対してはコレクタを具備せしめたアー
ムを許容範囲内で上下方向に揺動即ち俯仰するようにな
している。This meandering can be easily overcome by making the collector a double-oscillation type, but to prevent the trolley wire from sagging, the arm equipped with the collector can be moved up and down within the allowable range. It is made to oscillate, that is, to look up and down.
このアームの俯仰角度の規制はアームもしくはアームを
その下部側で枢着したスイベルにストッパーを突出せし
めこのストッパーへのアーム又はスイベルを当接して行
なっている。The angle of elevation of the arm is regulated by protruding a stopper from the arm or a swivel to which the arm is pivoted at its lower side, and by abutting the arm or swivel against the stopper.
従ってアームが強く揺動し大きな衝激力を繰り返しスト
ッパーに加えると該ストッパーが疲労し破損する虞れが
ある。Therefore, if the arm swings strongly and a large impact force is repeatedly applied to the stopper, the stopper may become fatigued and break.
本考案は突起状のストッパーをなくし、且アームの俯仰
角を確実に規制せんとしてなしたもので、以下図面によ
り詳細に説明する。The present invention eliminates the protruding stopper and reliably regulates the angle of depression and elevation of the arm, and will be described in detail below with reference to the drawings.

。In the figure, reference numeral 1 denotes a swivel rotatably provided on a fixture 2 fixed to a traveling body such as a crane hoist, and the lower ends of an arm 3 and an auxiliary arm 4 are pivotally attached to this swivel 1. Mounting base 5 on the upper end side of the auxiliary arm 4
A collector 6 equipped with a shoe on the mounting base 5 is made to easily and reliably follow the trolley wire by a double swing type or other method to ensure power supply from the trolley wire.
このアーム３とスイベル１間には引張用のばね７を設は
アーム３を該ばね圧にて上方向に揺動即ちアーム上端の
コレクタ６をトロリー線Ｔに圧接せしめ給電を確実に行
えるようになす。A tension spring 7 is provided between the arm 3 and the swivel 1 so that the arm 3 is swung upward by the spring pressure, that is, the collector 6 at the upper end of the arm is brought into pressure contact with the trolley wire T to ensure power supply. Eggplant.

直位置より角度θだけ揺動した位置でも平径部が嵌合で
きるような形状即ち円径の両側を山形に内方にくぼんだ
形状とする。The shaft 7 of the arm 3, which is pivotally connected to the swivel 1, has the part that fits into the fitting hole of the swivel 1 grounded on both sides to form a flat diameter part 7a, as detailed in FIG. 2 and below. The flat diameter portion 7a of the shaft fits into the fitting hole H, and the shaft remains flat even at a position swung by an angle θ from the vertical position of the flat diameter portion 7a so that the arm can swing within a set elevation angle range. The shape is such that the diameter portion can be fitted, that is, the shape is such that both sides of the circular diameter are concave inward in a chevron shape.
即ち嵌合孔Ｈは軸７の円径部と接する円弧形の孔縁Ｈａ
と山形に内方にくぼんだ斜め直線部縁Ｈｂ、Ｈｃとより
形成されるものである。That is, the fitting hole H has an arc-shaped hole edge Ha that contacts the circular diameter portion of the shaft 7.
and diagonal straight portion edges Hb and Hc that are inwardly recessed into a chevron shape.
而してアームが俯仰する際、軸７はアーム下端に固着さ
れているためアームの俯仰によって且その俯仰角に応じ
て軸も同角度のみ回動する。When the arm is raised or lowered, since the shaft 7 is fixed to the lower end of the arm, the shaft also rotates by the same angle as the arm is raised or lowered and in accordance with the angle of elevation.
この時の軸の回動角はアームの俯仰する揺動角と等しく
なり、このアームは水平状態よりコレクタ側が少し低く
なる位置より約２０数度の傾斜角までを揺動するものと
するが、この角度は一例であって給電装置の形状や取付
状態等に応じて変更されるものである。The rotation angle of the shaft at this time is equal to the swing angle of the arm when it is raised or raised, and the arm is assumed to swing up to an inclination angle of approximately 20 degrees from a position where the collector side is slightly lower than the horizontal state. This angle is just an example, and may be changed depending on the shape of the power supply device, the mounting state, etc.
アームが水平もしくは水平より少し下方に傾斜した最低

面すが嵌合孔のＨｃと夫々接した状態でこれ以上の押下
刃が働いてもアームは軸の平径部と嵌合孔孔縁とにより
ストッパー状となり規制される。When the arm is horizontal or in the lowest position tilted slightly below horizontal, the flat diameter surface a of the shaft is in contact with the Hb of the fitting hole H, and the flat diameter surface is in contact with the Hc of the fitting hole. Even if the push-down blade works, the arm becomes a stopper and is regulated by the flat diameter portion of the shaft and the edge of the fitting hole.
またアームがトロリー線の押下刃が解除された所謂アー
ムの無負荷時はばねの弾発力によりアームは押し上げら

接触しそれ以上の押上が規制されこれによってアームの
揺動許容範囲角θを規制するものである。Also, when the arm is unloaded, in which the push-down blade of the trolley wire is released, the arm is pushed up by the elastic force of the spring, and the flat diameter surface a of the shaft becomes Hc of the fitting hole, and the flat diameter surface Hb of the fitting hole, respectively. This restricts the arm from being pushed up further upon contact, thereby restricting the allowable swing range angle θ of the arm.
本考案によればアームを枢着する軸に平径部を形成し、
この軸を嵌合支持するスイベルにこの軸の平径部の揺動

でアームの揺動許容角度が定められ、且ストッパー等の
突起物がないので外観が良く、又アーム俯仰が繰り返し
行なわれてもその規制は確実である等の利点がある。According to the present invention, a flat diameter portion is formed on the shaft to which the arm is pivotally connected,
The permissible swing angle of the arm is determined by simply fitting the shaft into a fitting hole drilled in a swivel that supports the shaft to restrict the swing angle of the flat diameter part of the shaft. Since there are no protrusions, the appearance is good, and even if the arm is repeatedly raised and raised, it has the advantage of being reliably regulated.
