COMBINED OPERATION TYPE ATTACHMENT FOR CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To increase timing for changing over from one of the actuators to the other actuator at a combined operation type attachment for construction machine so as not to apply any limitation to an operation of the other actuator.SOLUTION: This invention relates to a combined operation type attachment 1 constituted in such a way that a bridge circuit 25 is arranged over two main pipings connected to a hydraulic direct-acting cylinder 2, the two branch pipings connected to a hydraulic rotation motor 3 are connected to a high pressure side and a low pressure side of said bridge circuit 25, a solenoid changing-over valve 35 is arranged to change-over either a flowing or shutting of oil at each of said branch pipings, a hydraulic power generating motor 4 is arranged at a bypass piping 43 from said solenoid change-over valve 35 to a location near the bridge circuit 25 to connect said two branch pipings, a valve control part 11 is directly supplied from a generator 41 rotated by said hydraulic power generating motor 4 and it is connected to the solenoid changing-over valve 35 through an operating line.SELECTED DRAWING: Figure 1
【課題】建設機械の複合動作型アタッチメントにおいて、アクチュエータの一方からアクチュエータの他方に切り換えるタイミングを増やし、アクチュエータの他方の作動に制限を課さない。【解決手段】ブリッジ回路25が、油圧直動シリンダ２に繋がる２つの主配管に跨がって設けられ、油圧回転モータ３に繋がる２つの分岐配管が、前記ブリッジ回路25の高圧側及び低圧側に接続され、電磁切換バルブ35が、前記分岐配管それぞれの油の流通又は遮断を切り換えられるように設けられ、油圧発電モータ４が、前記電磁切換バルブ35からブリッジ回路25寄りで前記２つの分岐配管を繋ぐ迂回配管43に設けられ、バルブ制御部11が、前記油圧発電モータ４が回す発電機か41ら直接給電され、電磁切換バルブ35と操作線により繋がれて構成される複合動作型アタッチメント１である。【選択図】図１
