上部旋回体側に前記グラッブラ一を設けることを特徴としている。 It is characterized in that the grabber is provided on the upper revolving structure side.
かかる構成によれば、 グラップラーによる把持位置と、 ソ一による切断位置と が互いに離間しているため、 グラッブラ一が切断済みワークの端部を把持するこ とがなく、 しかも切断済みワークの重心位置でも把持可能となる。 一方、 ソーを 下部走行体側に設けた分だけ、 作業時の車両重心を低くできる。 またソ一の取付 け部を接地させれば、 車両の転倒角を高めることができる。 即ち、 車両の安定性 を高めることができ、 高効率で安全作業を行える。 According to this configuration, since the gripping position by the grappler and the cutting position by the saw are separated from each other, the grabber can grip the end of the cut work. In addition, the workpiece can be gripped even at the position of the center of gravity of the cut work. On the other hand, the center of gravity of the vehicle during work can be lowered by the amount of the saw provided on the lower traveling body side. Also, if the mounting portion of the software is grounded, the falling angle of the vehicle can be increased. That is, the stability of the vehicle can be enhanced, and safe work can be performed with high efficiency.
また、 上記構成において、 ソーを鉛直軸回りに回転自在に設け、 又は水平方向 に移動自在に設けてもよい。 かかる構成により、 ワークを高効率で切断できる。 尚、 ソ一を鉛直軸回りに回転自在に設け、 かつ水平方向に移動自在に設ければ、 切断の自由度が増し、 その分さらに効率的な作業が行える。 またソーを俯仰自在 に設けてもよい。 かかる構成により、 切断位置の調整を自在に行える。 尚この場 合、 ソ一の向きを 9 0 ° 変えれば、 その方向への切断も可能となる。  Further, in the above configuration, the saw may be provided so as to be rotatable around a vertical axis, or may be provided so as to be movable in a horizontal direction. With this configuration, the work can be cut with high efficiency. In addition, if the software is provided so as to be rotatable about a vertical axis and movable in the horizontal direction, the degree of freedom of cutting is increased, and more efficient work can be performed. Also, the saw may be provided so as to be able to be raised. With this configuration, the cutting position can be adjusted freely. In this case, if the direction of the platform is changed by 90 °, it is possible to cut in that direction.
また上記構成において、 グラップラ一を回転自在に設けてもよい。 かかる構成 により、 ワークの把持が容易となるばかりか、 切断完了ワークを水平に、 また斜 めにも把持姿勢を変更でき、 高効率の安全作業を行える。 図面の簡単な説明  In the above configuration, the grappler may be rotatably provided. With this configuration, not only is it easy to grip the work, but also the gripping posture can be changed when the cut completed work is horizontal or inclined, and highly efficient safe work can be performed.

On the other hand, the movement S 4 of the saw 3 is performed by a hydraulic cylinder for moving the saw (e.g., not shown) installed between the base end of the saw 3 and the guide frame 12. Done in In addition, the saw 3 is provided with a hydraulic motor (not shown) for driving a saw chain at its base end, and the saw motor is driven to rotate by the hydraulic motor to cut the work. The two arms 11 on each of the right and left sides are connected to a hydraulic cylinder
(図示せず） によって俯仰自在 S 5とされている。 この俯仰 S 5によってソ一 3 も上下方向に俯仰 S 5するから、 この油圧シリ ンダはソー俯仰用油圧シリ ンダと なる。 (Not shown) and it can be raised and lowered S5. The hydraulic cylinder becomes a hydraulic cylinder for raising the saw because the lifter S5 also raises the vertical direction S5 by the elevation S5.
一方、 上部旋回体 2側にはグラップラー 4が設けてある。 詳しくは次の通り。 上部旋回体 2上には、 運転席 2 1 と、 車両の駆動源 2 2と、 第 1アーム 2 3の基 端とが設けてある。 第 1アーム 2 3は、 油圧シリ ンダ 2 3 1によって前記基端回 りに上下方向に俯仰自在 S 6とされている。 第 1アーム 2 3の先端には、 油圧シ リ ンダ 2 3 2によって上下方向に俯仰自在 S 7とされた第 2アーム 2 4が設けて ある。 第 2アーム 2 4は回転モータ 2 4 1を備え、 先端側を回転自在 S 8とされ ている。 そして回転自在 S 8 とされた前記先端側には、 油圧シリ ンダ 2 4 2によ つて開閉自在 S 9とされた 2本のダラッブラー 4が対向して設けてある。 尚、 前 記駆動源 2 2は、 エンジンやこのエンジンで駆動される油圧ポンプ等からなる。 この油圧ポンプからの圧油は、 運転席 2 1からの信号に基づき、 前記各油圧モー タゃ各油圧シリ ンダに送られ、 これらを作動させる。  On the other hand, a grappler 4 is provided on the upper revolving superstructure 2 side. Details are as follows. A driver's seat 21, a vehicle drive source 22, and a base end of a first arm 23 are provided on the upper revolving superstructure 2. The first arm 23 is made up and down vertically S6 around the base end by a hydraulic cylinder 23 1. At the tip of the first arm 23, a second arm 24 is provided, which is made up and down S7 by a hydraulic cylinder 232. The second arm 24 is provided with a rotary motor 241, and the tip side is rotatable S8. Two doublers 4, which can be opened and closed by hydraulic cylinders 24, are provided opposite to each other at the front end, which is made rotatable S 8. The drive source 22 includes an engine, a hydraulic pump driven by the engine, and the like. The hydraulic oil from the hydraulic pump is sent to each hydraulic motor and each hydraulic cylinder based on a signal from the driver's seat 21 to operate them.
上記第 1事例の代表的操作例を説明する。 ワーク 5が例えば電柱であったとす る。 この時、 オペレータは上部旋回体 2を旋回 S 1 させ、 車両を前後進 S 2させ 、 第 1アーム 2 3を俯仰 S 6させ、 第 2アーム 2 4を俯仰 S 7させ、 また第 2ァ —ム 2 4の先端部を回転 S 8させ、 これらによりワーク 5に対する最適な把持位 置及び切断位置を得る。 次いでグラップラー 4を閉じ S 9、 これにより電柱 5の 上部を把持する。 その後、 ソ一 3で電柱 5の下部を切断する。 このときの切断高 さの調整はアーム 1 1を俯仰 S 5させて行い、 一方、 切断自体はソー 3の左右方 向への回転 S 3及び移動 S 4のいずれか一方又は両方で行う。 切断を完了すると 、 アーム 1 1を伏せ S 5、 また案内フレーム 1 2を接地させ、 これにより車両の 安定性を増加させる。 尚、 切断開始前に案内フレーム 1 2を接地させてあるなら ば、 この操作は不要である。 またワーク 5が軽量であるならば、 案内フ レーム 1 2を接地させる必要はない。 その後、 オペレータは、 上記旋回 S 1、 前後進 S 2 、 俯仰 S 6、 俯仰 S 7、 回転 S 8及び開閉 S 9を組み合わせて、 切断電柱 5を所 定位置に横たえる。 ここで、 第 1事例は、 第 2アーム 2 4に回転モータ 2 4 1を 備えて先端側を回転自在 S 8としてあるから、 回転モータ 2 4 1で第 2アーム 2 4の先端側を回転 S 8させることにより切断電柱 5を回転させて切断電柱 5を方 向自在に横たえることができる。 尚、 第 2アーム 2 4に回転モータ 2 4 1を備え ない場合であれば、 切断電柱を旋回 S 1の中心から放射状に横たえることになる 他の事例を項目列記する。 A representative operation example of the first case will be described. Assume that the work 5 is, for example, a telephone pole. At this time, the operator turns the upper-part turning body 2 to turn S 1, moves the vehicle forward and backward S 2, raises the first arm 23 3 to elevate S 6, makes the second arm 24 4 to elevate S 7, and moves the second arm 2. The tip of the robot 24 is rotated S8 to obtain the optimum gripping position and cutting position with respect to the workpiece 5. Next, the grappler 4 is closed and S 9, thereby gripping the upper part of the utility pole 5. After that, the lower part of the utility pole 5 is cut off with the software 3. Cutting height at this time The adjustment of the height is performed by lowering the arm 11 to S5, while the cutting itself is performed by one or both of the rotation S3 of the saw 3 in the left-right direction and the movement S4. When the cutting is completed, the arm 11 is turned down S5 and the guide frame 12 is grounded, thereby increasing the stability of the vehicle. This operation is unnecessary if the guide frame 12 is grounded before the start of cutting. If the work 5 is lightweight, it is not necessary to ground the guide frame 12. Thereafter, the operator lays the cutting utility pole 5 at a predetermined position by combining the above-mentioned turning S1, forward and backward S2, elevation S6, elevation S7, rotation S8, and opening and closing S9. Here, in the first case, since the second arm 24 is provided with a rotary motor 241, and the distal end is rotatable as S8, the rotary motor 241 rotates the distal end of the second arm 24. 8, the cutting utility pole 5 can be rotated and the cutting utility pole 5 can be laid freely. If the second arm 24 is not provided with the rotary motor 241, the cutting utility pole will lie radially from the center of the turn S1.
( 1 ) 上記第 1事例の本体は、 油圧式ショベルであるが、 上記第 1事例のよう な第 2アーム 2 4ではなく、 油圧式ショベル本来の第 2アームの先端にバゲッ 卜 に代えて上記グラップラ一 4を設けてもよい。 尚、 小形油圧式ショベルならば、 下部走行体 1側にブレードやアウ トリガを有しているのが普通であるから、 ブレ ―ドを支持するアーム 1 1 に、 ブレードに代えてソー 3を設けてもよく、 またァ ゥ ト リガのフレームや伸縮脚等にソ一 3を設けてもよい。  (1) Although the main body of the first case is a hydraulic shovel, it is not the second arm 24 as in the first case, but instead of a baggage at the tip of the original second arm of the hydraulic shovel. Grapplers 14 may be provided. Since a small hydraulic excavator usually has a blade or an outrigger on the undercarriage 1 side, a saw 3 is provided on the arm 11 supporting the blade instead of the blade. Alternatively, the software 3 may be provided on a frame or a telescopic leg of the trigger.
( 2 ) 上記第 1事例では、 図 1に示した通り、 第 2アーム 2 が短いため、 グ ラップラ一 4によるワーク 5の把持高さの調整は僅かしか行えないが、 第 2ァー ム 2 4の先端部に上下方向へのスライ ド部材を設け、 このスライ ド部材上にダラ ップラー 4をスライ ド可能に設ければ、 グラップラー 4によるワーク 5の把持高 さの調整は自在に行える。 尚、 第 2アーム 2 4を長くするだけでも、 グラップラ 一 4によるワーク 5の把持高さの調整は自在に行える。  (2) In the first case, as shown in Fig. 1, the second arm 2 is short, so that the gripper 14 can only slightly adjust the gripping height of the work 5; however, the second arm 2 If a vertical slide member is provided at the distal end of 4 and the dapper 4 is slidably provided on this slide member, the gripping height of the work 5 by the grappler 4 can be adjusted freely. In addition, it is possible to freely adjust the gripping height of the work 5 by the grappler 14 simply by making the second arm 24 longer.
( 3 ) ソ一 3の作動は、 上記第 1事例では回転 S 3、 移動 S 4及び俯仰 S 5と したが、 案内フレーム 1 2を、 別途設けた油圧シリ ンダや油圧モータ等を用いて 鉛直軸回りや水平軸回りに回転させても良い。 このようにすると、 作業自由度が 増大し、 その分、 作業効率が相乗的に向上する。 産業上の利用可能性 (3) In the first case above, the operation of the so-called 3 is the rotation S3, the movement S4, and the elevation S5. However, the guide frame 12 may be rotated around a vertical axis or a horizontal axis using a separately provided hydraulic cylinder or hydraulic motor. In this way, the degree of freedom of work is increased, and the work efficiency is correspondingly improved. Industrial applicability
