【考案の詳細な説明】
本考案は小さい旋回半径を得ることが可能な油圧式パワ
ーショベルの小旋回装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small turning device for a hydraulic power shovel that can obtain a small turning radius.
一般に油圧式パワーショベルは、第１図に示すように履

れぞれ仰俯自体に連結してなり、これらの作動を油圧モ
ータ、油圧シリンダ等により行っている。In general, a hydraulic power excavator has a revolving body supported rotatably on a lower running body a using crawlers, as shown in Fig. 1, and a boom C, an arm d, and a bucket (e) are mounted on the revolving body. It is connected to the elevation itself, and these operations are performed by a hydraulic motor, hydraulic cylinder, etc.
そして旋回体すが旋回した場合、旋回によりショベル本
体の最先端部が描く軌跡と旋回中心との距離を旋回半径
Ａと呼んでいる。When the revolving body turns, the distance between the center of the swing and the trajectory drawn by the most extreme part of the excavator body due to the swing is called the turning radius A.
そこで住宅地などの狭い道路での下水道工事等では、こ
の旋回半径Ａが大きい油圧式パワーショベルを用いると
、パワーショベルの特色である掘削→旋回→ダンプ積込
の一連の作業が困難又は不可能で、従って作業能率も上
がらなかった。Therefore, for sewerage work on narrow roads such as in residential areas, if a hydraulic power shovel with a large turning radius A is used, it will be difficult or impossible to carry out the series of tasks that are characteristic of a power shovel, such as digging, turning, and loading a dump truck. Therefore, work efficiency did not improve.
また旋回半径の小さいミニショベルを用いると、掘削深
さが充分確保できず、最終的には人力による掘削作業を
行なわなければならず、作業効率が悪かった。Furthermore, when a mini excavator with a small turning radius is used, a sufficient digging depth cannot be ensured, and ultimately the excavation work must be carried out manually, resulting in poor work efficiency.
さらにまた油圧式パワーショベルの旋回半径Ａを小さく

すようにしたものも考えられ、第３図に示すようにブー
ム用シリンダｈのストロークを延長してブームＣを後方
に倒す。Furthermore, in order to reduce the turning radius A of the hydraulic power shovel, as shown in FIG. It is also conceivable that the excavator main body f is tilted backwards, and the boom C is tilted backwards by extending the stroke of the boom cylinder h, as shown in FIG.
しかしこのブームＣを後方に倒す方式では、ブーム用シ
リンダｈとブームＣを揺動自在に取付けであるピンｇの
距離りが小さくなり、ブーム用シリンダｈによる持上げ
力が大巾に減少し、作業能率の低下をきたす欠点がある
。However, in this method of tilting the boom C backwards, the distance between the boom cylinder h and the pin g that swings the boom C becomes smaller, and the lifting force by the boom cylinder h is greatly reduced, making it difficult to carry out work. It has the disadvantage of reducing efficiency.
そこで本考案は前記欠点を除去し、本来の油圧式パワー
ショベルのもつ性能を損うことなく狭い道路でも掘削→
旋回→ダンプ積込の一連の作業を可能とする油圧式パワ
ーショベルの小旋回装置を提供することを目的としたも
のである。Therefore, the present invention eliminates the above drawbacks and excavates even on narrow roads without sacrificing the performance of the original hydraulic power excavator.
The object of the present invention is to provide a small swing device for a hydraulic power shovel that enables a series of operations from swing to dump loading.
