Control System Design Of HR150 Rotary Drilling Rig

Infrastructure construction during the development of a country period, in the infrastructure construction process needs of pile diameter in 1.2m below, depth in 40m within. The Rotary Drilling Rig with torque, flexible, low noise, high efficiency, drilling construction site neat etc become common pile work machinery.Sufficient research on drilling machine of practical application and analysis the current available large drilling equipment technical features and HR150 of HCM the rotating drill, puts forward the hydraulic system overall design scheme and the main actuators institutions of hydraulic drive system (main volume, deputy coil, turn and walk device, main branch) design scheme, completed restricts the rotating drill agility and controlling the pilot control part of the detailed design. To pilot control hydraulic system important components e-style proportional pressure reducing valve is analyzed theoretically, and obtain the transfer function and static characteristics. When the design AMESim establish valve using simulation model, and carry on the simulation analysis, then to the rotating drill the pilot control system for system modeling and simulation proves its system practicability and rationality. Finally EPEC2024 controller based on CAN bus is introduced to the micro electric control system, completes the control system hardware structure and software flow chart of main parts design.The hydraulic system installed and start debugging, using the pilot control system can solve the operational problems, realized the manipulation of the input power and output pressure and reduce the operator is proportional to the working strength has good handling of other types of the rotating drill has guiding significance for the hydraulic system.
