Research And Design On Rotary Drilling Rig’s Hydraulic System

Recently,rotary drilling rig is fast development machine with our country highway and railway project construction. After the year 2007,the rotary drilling rig marketing is promoted more than fifty percent every year. After the year 2012, the rotary drilling rig marketing is a little gliding, but the applying is still widely using. Rotary drilling rig is widely used in highways, railways, bridges, civil engineering field.As a large-scale construction equipment of rotary drilling rig,the complex structure,electromechanical integration gree is relatively high, full hydraulic drive, complex hydraulic system.Firstly, rotary drilling rig, research status and development trends are introduced, a comprehensive comparison of domestic and foreign technical characteristics of rotary drilling rig. The second chapter is the introduction of rotary drilling rig chassis, electrical system, working device, the paper introduces the application of hydraulic transmission technology in rig, clarify the importance ofdigging hydraulic transmission technology in development of rotary drilling rig.The article began a detailed design of SER22 type rotary for a company’s dig rig hydraulic system from the third chapter. Perform more actions of rotary drilling rig working device, the design of complex hydraulic system, the system design at the beginning to determine the main parameters of the rig and control mode, and then focus on the overall design of the system from several mainpoints, system mainly includes the design of power head system, the design of the main winch system, design of auxiliary winch system, rotary system design, walking system design, cooling system design, system design mainly includes the design principle and components selection, calibration calculation etc.After the design of SER22 type rotary drilling rig hydraulic system needs to be verified, this paperused AMEsim software to analysis the simulation. Because t. Because the rotary drilling rig hydraulic system complex, hydraulic system to develop the analysis of the overall difficulty is large, the fourth chapter is mainly through the AMEsim simulation design of hydraulic system of power head, through the simulation of dynamic head system design of the hydraulic system, according to the data of verification, to determine the reliability of hydraulic design.
