ROTATION SUPPORT DEVICE FOR WORK MACHINE
PROBLEM TO BE SOLVED: To provide a rotation support device of a work machine, which is capable of appropriately avoiding a contact between a work tool of a front work machine and a transport vehicle during rotation of a rotating body.SOLUTION: A control device 21 according to this invention comprises: a contact determination part 24, which determines whether or not a bucket 4C contacts with a dump truck 100 on the basis of a target rotation angle calculated by a difference calculation part 23a, a target travel calculated by a difference calculation part 23b, a rotation speed of a rotating body 3 calculated by a signal conversion part 22a, and a travel speed of the bucket 4C calculated by a signal conversion part 22b; a speed relation setting part 25, which sets a relation between a rotation speed and a travel speed to avoid the contact between the bucket 4C and the dump truck 100 when the contact determination part 24 has determined that the bucket 4C contacts with the dump truck 100; and a speed control part 30, which controls the rotation speed of the rotating body 3 and the travel speed of the bucket 4C according to the relation set by the speed relation setting part 25.SELECTED DRAWING: Figure 4
【課題】旋回体の旋回動作において、フロント作業機の作業具と運搬車両との接触を的確に回避することができる作業機械の旋回支援装置の提供。【解決手段】本発明の制御装置２１は、差分演算部２３ａで演算された目標旋回角度、差分演算部２３ｂで演算された目標移動量、信号変換部２２ａで演算された旋回体３の旋回速度、及び信号変換部２２ｂで演算されたバケット４Ｃの移動速度に基づいて、バケット４Ｃとダンプトラック１００が接触するかどうかを判定する接触判定部２４と、接触判定部２４でバケット４Ｃとダンプトラック１００が接触すると判定されたとき、バケット４Ｃとダンプトラック１００との接触を回避する旋回速度と移動速度との関係を設定する速度関係設定部２５と、速度関係設定部２５で設定された関係に応じて、旋回体３の旋回速度及びバケット４Ｃの移動速度を制御する速度制御部３０とを具備する。【選択図】図４
