Abstract
Description
【発明の詳細な説明】
本発明は、バックホー−クラムシェル等の上部旋回体が
下部機構に対して３６０°全旋回しうるタイプの掘削機
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an excavator of a type in which an upper revolving body such as a backhoe-clamshell can rotate a full 360° relative to a lower mechanism.
従来のこの種の掘削機においては・第１図に示すように
、ブーム等の作業装置（１）と油圧装置（２）エンジン
（３）などが一体的に上部旋回体（４）を構成しており
、必然的に、この上部旋回体（４）の回動軌跡イは走行
装置（５）などの下部機構（６）より大きなスペースと
なる。それで、従来のこの種の掘削機を狭（・場所に導
入して作業を行なった場合、上部旋回体（４）の旋回時
にこれが周囲の家屋などに接触又しま衝突する虞れが多
く、結局、掘削した土をダンプに積込む作業ができない
。しかし最近は、狭隘な市街地での“掘削作業は多く、
こ〜で円滑かつ能率的に掘削作業を行なうことができる
機械の導入が要請されている。In a conventional excavator of this type, as shown in Figure 1, a working device (1) such as a boom, a hydraulic system (2), an engine (3), etc. integrally constitute an upper revolving body (4). Therefore, the rotation trajectory of the upper revolving structure (4) inevitably takes up a larger space than the lower mechanism (6) such as the traveling device (5). Therefore, when a conventional excavator of this type is installed in a narrow place for work, there is a high risk that when the upper revolving structure (4) turns, it will come into contact with surrounding houses, etc., or collide with the surrounding buildings. , it is not possible to load the excavated soil into a dump truck.However, recently there has been a lot of excavation work in narrow urban areas.
There is a demand for the introduction of machines that can perform excavation work smoothly and efficiently.
本発明はこのような実状に鑑みその要請に応えてなされ
たもので、機体中の範囲内にある狭隘な場所での円滑に
して能率的な掘削作業が行える構造簡単にして新規な掘
削機を提供することを目的とする。The present invention has been made in response to the request in view of the above-mentioned circumstances, and provides a novel excavator with a simple structure that enables smooth and efficient excavation work in narrow spaces within the machine body. The purpose is to provide.
以下、本発明を図示する実施例を参照しながら説明する
。なお、従来の実施例と共通する部分は同一の符号を使
用するものとする。The invention will now be described with reference to illustrative embodiments. Note that the same reference numerals are used for parts common to the conventional embodiment.
第２図において、上部旋回体（４）は、旋回台（４ａ）
上に作業装置（１）を構成しているく字状ブーム（ｌａ
）が油圧シリンダ（２ａ）によって傾斜角度調整可能に
枢着され、またそこに運転席（７）が設置されてなる。In FIG. 2, the upper rotating body (4) is a rotating base (4a).
A dogleg-shaped boom (la
) is pivotally connected by a hydraulic cylinder (2a) so that its inclination angle can be adjusted, and a driver's seat (7) is installed there.
該く字状ブーム（ｌａ）の先端側には油圧シリンダ（２

ンダ（２Ｃ）によってパケット（ＩＣ）が回転可能に枢
着される。A hydraulic cylinder (2
b), the excavating arm (1b) is pivotally attached to the excavating arm (1b) so that its angle can be adjusted, and furthermore, a packet (IC) is rotatably attached to the distal end side of the excavating arm (1b) by a hydraulic cylinder (2C).
下部機構（６）は、油圧タンク・ポンプなどからなる油
圧装置（２）・原動機（３）・走行装置（５）などで構
成される。The lower mechanism (6) includes a hydraulic system (2) including a hydraulic tank and pump, a prime mover (3), a traveling device (5), and the like.
上部旋回体（４）の旋回中心軸は下部機構（６）の前後
全長を二分しかつ左右中（第３図）を二分する点に立つ
垂直線口と一致し、該上部旋回体（４）の旋回軌跡の最
小巾ｌが下部機構（６）の中肉におさまるよう位置付け
られている。The central axis of rotation of the upper revolving body (4) coincides with a vertical line opening that bisects the entire front and back length of the lower mechanism (6) and the left and right center (Fig. 3), and the upper revolving body (4) The lower mechanism (6) is positioned such that the minimum width l of the turning locus fits within the inner wall of the lower mechanism (6).
而して、上述のように構成された掘削機を市街地の狭隘

パケット（１ｃ）に掬った掘削土は、上部旋回体（４）

方に待機しているダンプに繰返し放出する。Therefore, when using the excavator configured as described above for excavation work such as "narrow roads in urban areas", the upper revolving body (4) is set to the minimum width l of the revolving trajectory. When the excavator runs, it can be smoothly introduced into the narrow road equivalent to the lower mechanism (6).Then, the narrow road in front of the excavator is excavated and the excavated soil scooped into the packet (1c) is transferred to the upper revolving structure (4).
The robot then makes a 180° turn within the minimum turning trajectory and repeatedly discharges it to a dump truck waiting on one side.
′以上述べたように、本発明によれば、狭隘な場所での
掘削作業が上部旋回体を家屋などに接触又は衝突される
ことなく円滑かつ能率的に行なうことができる。As described above, according to the present invention, excavation work in a narrow space can be carried out smoothly and efficiently without the revolving superstructure coming into contact with or colliding with a house or the like.
