PILE PRESS-IN DEVICE, PILE PRESS IN SYSTEM, AND PILE PRESS-IN METHOD
To provide a pile press-in device to allow an output control to be flexible performed.SOLUTION: A pile press-in device is provide with: a hydraulic motor and a drive gear to rotate a chuck body; a rotational hydraulic control valve 73A to transfer driving force from a hydraulic unit 6A to a hydraulic motors 36A1 to 36A3; a rotational hydraulic control valve 73B to transfer driving force from a hydraulic unit 6B to a hydraulic motors 36B1 to 36B3; and a connection control circuit 80X to change connection states including a transmission state and a non-transmission state between rotational hydraulic control valves 73A, 73B. When the connection control circuit is in the transmission state, the driving force from the hydraulic unit 6A is transferred to hydraulic motors 36A1 to 36A3 and 36B1 to 36B3 through the rotational hydraulic control valve 73A as well as transferred to hydraulic motors 36B1 to 36B3 through the rotational hydraulic control valves 73A, 73B, and when in the non-transmission state, the driving force from the hydraulic unit 6A is transferred to the hydraulic motors 36A1 to 36A3 without transmission to the hydraulic motors 36B1 to 36B3.SELECTED DRAWING: Figure 4
【課題】柔軟な出力制御が可能な杭圧入装置の提供。【解決手段】杭圧入装置は、チャック本体に回転を付与する油圧モータ及び駆動ギアと、油圧ユニット６Ａからの駆動力を油圧モータ３６Ａ１〜Ａ３に伝達する回転油圧制御バルブ７３Ａと、油圧ユニット６Ｂからの駆動力を油圧モータ３６Ｂ１〜Ｂ３に伝達する回転油圧制御バルブ７３Ｂと、回転油圧制御バルブ７３Ａ、７３Ｂの間で伝達状態と非伝達状態とを含む接続状態を切り替える接続制御回路８０Ｘとを備える。接続制御回路が伝達状態のときは、油圧ユニット６Ａからの駆動力は、回転油圧制御バルブ７３Ａを介して油圧モータ３６Ａ１〜Ａ３、３６Ｂ１〜Ｂ３に伝達されるとともに、回転油圧制御バルブ７３Ａ、７３Ｂを介して油圧モータ３６Ｂ１〜Ｂ３にも伝達され、非伝達状態のときは、油圧ユニット６Ａからの駆動力は、油圧モータ３６Ａ１〜Ａ３に伝達され、油圧モータ３６Ｂ１〜Ｂ３に伝達されない。【選択図】図４
