OPERATION SUPPORTING DEVICE OF REVOLVING SUPERSTRUCTURE
To provide an operation supporting device of a revolving superstructure which can perform an operation at low cost and with simple control and in which an operator can easily utilize an operation supporting function.SOLUTION: When a transport vehicle 31 is recognized around a hydraulic shovel 1 based on images captured by a camera 28, a bird's-eye image showing positional relation of the transport vehicle 31 with own vehicle 1 as a reference is generated and displayed on a display 29, and an upper part of a vessel 31a of the transport vehicle 31 is set as a target stop position of revolving. According to revolving of a revolving superstructure 5 by operation of a revolving operation lever 18, the positional relation between the hydraulic shovel 1 and the transport vehicle 31 in the bird's-eye image is changed. When the revolving operation lever 18 is operated toward the target stop position of revolving, a braking angle θ from stoppage of the lever operation to stop of the revolving superstructure 5 is calculated, a marker 32 of an estimated stop position of revolving is displayed at the target stop position of revolving side by the braking angle θ with a work device 10 as a reference, and an operator determines stoppage timing of the lever operation based on the display.SELECTED DRAWING: Figure 4
【課題】低コスト且つ簡単な制御により実施できると共に、オペレータが容易に操作支援の機能を利用できる旋回体の操作支援装置を提供する。【解決手段】カメラ２８の撮像画像に基づき油圧ショベル１の周辺に運搬車３１を認識すると、自車１を基準とした運搬車３１の位置関係を示す俯瞰画像を作成してディスプレイ２９に表示すると共に、運搬車３１のベッセル３１ａ上を目標旋回停止位置として定める。旋回操作レバー１８の操作による上部旋回体５の旋回に応じて、俯瞰画像中の油圧ショベル１と運搬車３１との位置関係を変化させる。目標旋回停止位置に向けて旋回操作レバー１８が操作されると、レバー操作の中止から上部旋回体５が停止するまでの制動角θを算出し、作業装置１０を基準として制動角θだけ目標旋回停止位置側に旋回停止予測位置のマーカー３２を表示し、その表示に基づきオペレータにレバー操作の中止タイミングを判断させる。【選択図】図４
