CONTROL DEVICE FOR AREA LIMITING EXCAVATION OF CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a control device for area limiting excavation of a construction machine, the device that can improve excavation accuracy in the case when an operational speed of a driven member is relatively slow.SOLUTION: A control device for area limiting excavation of a construction machine includes a control unit 9 for performing area limiting control by controlling at least one of two or more hydraulic cylinders 3a, 3b, 3c based on each posture/position of a boom 1a, an arm 1b and a bucket 1c. The device includes: an angle detector group 8 for detecting a rotation angle of the boom 1a, the arm 1b and the bucket 1c; and a tilt angle detector group 81 for detecting a ground angle of the boom 1a, the arm 1b and the bucket 1c. The control unit 9 selects a detector for use in calculation of each posture/position of the boom 1a, the arm 1b and the bucket 1c from the angle detector group 8 and the tilt angle detector group 81 according to the magnitude of at least one speed among the boom 1a, the arm 1b and the bucket 1c.
【課題】被駆動部材の動作速度が相対的に遅い場合の掘削精度を向上できる建設機械の領域制限掘削制御装置を提供すること。【解決手段】ブーム１ａ、アーム１ｂおよびバケット１ｃのそれぞれの姿勢・位置に基づいて複数の油圧シリンダ３ａ，３ｂ，３ｃの少なくとも１つを制御することで領域制限制御を行う制御ユニット９を備える建設機械の領域制限掘削制御装置において、ブーム１ａ、アーム１ｂおよびバケット１ｃの回転角を検出する角度検出器群８と、ブーム１ａ、アーム１ｂおよびバケット１ｃの対地角を検出する傾斜角検出器群８１とを備える。制御ユニット９は、ブーム１ａ、アーム１ｂおよびバケット１ｃのうちの少なくとも１つの速度の大きさに応じて、ブーム１ａ、アーム１ｂおよびバケット１ｃのそれぞれの姿勢・位置の演算に利用する検出器を角度検出器群８と傾斜角検出器群８１の中から選択する。【選択図】図１５
