HYDRAULIC CIRCUIT FOR A CF RISE IN AN AUTOMATED CONSTRUCTION SYSTEM SYNCHRONIZING THE MOTION OF ALL HYDRAULIC ROBOTS BY A CONTROLLER WITH A CLOSED-LOOP CIRCUIT

摘要

PURPOSE: A hydraulic circuit for a CF rise in an automated construction system is provided to synchronously control the motion of all hydraulic robots through a closed-loop circuit, thereby maintaining a balance when a CF rises.;CONSTITUTION: A hydraulic circuit for a CF rise in an automated construction system comprises a closed-loop circuit(10), a load sensing circuit(20), and a fall prevention device(30). The closed-loop circuit synchronously controls a speed of a hydraulic cylinder and continuously compares an input and control output through a feedback to make the hydraulic robot stop at an arbitrary spot within an operation space. The load sensing circuit controls the discharging pressure of the hydraulic pump by connecting to load pressure. The fall prevention circuit is installed in a piston rod side circuit of the hydraulic cylinder, thereby preventing a falling phenomenon caused by the weight of the piston rod. The fall prevention circuit operates when the pressure of the circuit exceeds set-up pressure, thereby controlling system pressure.;COPYRIGHT KIPO 2013
