Claims (1)
- アタッチメントを作業機に着脱するための建設機械のクイックカプラー回路であって、
伸縮駆動してアタッチメントを作業機に保持/脱離させるクイックカプラーシリンダと、油圧ポンプと、油圧ポンプの強制昇圧を切り替える電磁切替バルブと、クイックカプラーシリンダに対する作動油の供給方向を切り替えてクイックカプラーシリンダを伸縮駆動させるためのカプラー切替バルブと、電磁切替バルブとカプラー切替バルブをそれぞれ切替制御する制御装置とを備え、
電磁切替バルブとカプラー切替バルブを切替操作するためのスイッチが、クイックカプラーシリンダを伸縮させてアタッチメントを保持する際のロックポジションと、クイックカプラーシリンダを伸縮させてアタッチメントを脱離させる際のアンロックポジションの2つのポジションで操作するように構成され、
制御装置は、スイッチをロックポジションあるいはアンロックポジションに操作して出力された操作信号を受けて、カプラー切替バルブを切替制御するとともに、スイッチの操作によって油圧ポンプの昇圧が始まるように、且つ所定の時間が経過した段階で油圧ポンプの昇圧が終了するように、電磁切替バルブを切替制御することを特徴とする建設機械のクイックカプラー回路。
