Study On Multifunctional Rotary Mast Of The Piling Machinery

With the rapid growth of the world economy,more and more high,heavy,large infrastructure,which requires the completion of related equipment.The full hydraulic crawler pile frame has the advantages of compact structure,strong applicability,and the utility model is a key component for ensuring the successful completion of the construction.On the basis of thorough investigation and research,combined with the structure,mechanism and advantages of various kinds of crawler pile frame at home and abroad.First of all domestic and international professional data,a detailed analysis of the structure and mechanism of various equipment of principle,operation characteristics,the multifunctional pile frame of the overall program,and the main parameters of the multifunctional pile frame is determined.Secondly,according to the actual situation and development requirements put forward the development of multifunctional rotary column,with multi-function rotary column identified as the main research object,combined with the construction requirements,the structure and mechanism of post process function and give a detailed analysis;combined with the specific circumstances of multifunctional column structure,a formula to calculate the column structure under external load under the effect of strength,stiffness and stability.Then,using the 3D engineering analysis software,this paper analyzes the function of the rotary column and the lifting system.The stress,strain and displacement of the column structure are analyzed in detail.The results show that all the mechanics(strength,stiffness and so on)and the mechanism(motion interference,etc.)meet the requirements.Finally,analyze the influence of the crawler pile frame grounding area on the stability;consider the front and center of gravity and lateral bias and a walking device with the car vertical direction of the three position,analysis of the crawler pile frame stability,determine the stability region of the crawler pile frame.Research and development of new multifunctional pile frame to meet the urgent needs of rapid development.space costs,reduce the burden of construction enterprises;at the same time,because the new multifunction pile frame construction efficiency is high,can bring good economic benefits to the enterprise.The development of a new type multifunctional pile frame will provide the products with independent intellectual property rights,and play a positive role in promoting the national economic construction and all the way forward.
