油圧ハンマの制御装置。 A pressure oil supply pipe connecting the discharge side of a hydraulic pump driven by a motor and an oil supply port of a hydraulic cylinder with a ram connected to a rod, and an oil drain side pipe connecting an oil drain port of the cylinder to a tank. In the hydraulic circuit of the hydraulic hammer, the pressure oil supply pipe and the oil discharge side pipe are connected via a relief valve with unloading, and the primary side of the solenoid switching valve is connected to the relief valve with unloading. The secondary side is connected to the unload side pipe of the ram via a relief valve to the drain oil side pipe, and the pressure of the relief valve is set lower than the pressure of the pressure oil supply pipe. The solenoid switching valve is switched by simultaneously operating the detection means for detecting the raised position of the ram and the detection means provided close to the hydraulic hammer for detecting the allowable rise height of the ram. Hydraulic hammer control device.
