Aiming at working conditions and functional requirements of a ZYWL -6000D full hydraulic directional drilling rig,an overall structural design scheme of the drilling rig composed of a single motor,a hydraulic system,and multi-actuator was presented here.In the hydraulic system,the load sensing pump control technology and the two-rank low-pressure valve control technology were adopted for the feed hydraulic circuit and rotary hydraulic circuit.In order to study the effecfs of the dynamic characteristics of the hydraulic system on the drilling rig,the dynamic simulation models of the feed hydraulic circuit and rotary hydraulic circuit were established and the simulations were performed by using Matlab SimHydraulics .The results showed that the designed drilling rig hydraulic system has good functions of overload protection and energy-saving,and rereals good dynamic performances.The results provided a foundation for drilling performance optimization.
