Rotary Drilling Rig Drilling Technology Research Based On The Proportion Of Electro-hydraulic Control Technology

Rotating drill is a kind of construction machinerys which is suitable for buildingfoundation. Mainly for sandy soil, cohesive soil and silty soil layer construction,ets. In thebored piles, continuous wall, and so on the many kinds of base construction of foundationreinforcement is widely used in domestic experts believe: rotating drill in China is still a bigmarket in the next few years.Therefore, the characteristics of rotating drill intelligent andtechnical analysis have great significance. With the development of science and technologyand the need of engineering application, the user have cost-saving requirements, and payattention to the construction cost evaluation of different equipment, society also needengineering machinery of energy conservation and environmental protection.the concept ofdesign is from the original functionality to the performance of the system level.The paper based based on the existing hydraulic and electronic control, analysis rotatingdrill intelligent technology, experiment, calculation and research, disease in SIMULATIONXsoftware to simulat the theoretical assumptions, based on the theory of component selectionand control design, system test, research in the actual construction, make feasible technologysolutions, which mainly involvs automatic return to the main winding bottom protection andwire rope pre-tightening technology and power head’s automatic drilling technology.Through experiment, the rotating drill’s intelligent control technology is feasible, whichunder the condition of current technology, adopt the electric control operation, simplify theinstallation, convenient maintenance, convenient diagnosis, at the same time can be achievedby program logic interlock between multiple actuators and linkage control, effectivelyimprove the performance security. Using the mature electric proportion control technology,can be simple to realize automation of drilling rig, improve the level of the whole rig designautomation, embody the people-oriented design concept.
