The invention discloses a hydraulic control system and a device used for the location of a ship body by sections. Three hydraulic cylinders that are mutually orthogonal are adopted; wherein, the piston rod of a hydraulic cylinder with a displacement sensor moves up and down; the other two hydraulic cylinders push the hydraulic cylinder to move front and back as well as left and right on a horizontal plane. The moving displacement on the horizontal plane of the hydraulic cylinder the piston rod of which moves up and down is monitored and recorded by a displacement sensor; the recorded data is input into a PCL control circuit, thereby further controlling the expansion amount of the other two hydraulic cylinders to be capable of ensuring the hydraulic cylinder the piston rod of which moves up and down to make translational motion on the horizontal plane. The system and the device of the invention can adjust and control the precise positions of up and down, front and back as well as left and right of the substances arranged at the hydraulic cylinder the piston rod of which moves up and down. Location with high precision can be carried out on the ship body by sections according to the free combinations of three or multiple devices.
