The Design And Study Of Three Drill Pipes Synchronous Migration Device Of Land Rig

Drill pipe’s Transport is a very important part of drilling process.In this way,the main operation mode is human operation,this way exists of large labor,low efficiency and more dangerous.With the improvement of the level of the drilling automation of land rig,the automatic level and efficiency of drill pipe transportation will be paid more and more attention.This topic is put forward in this context.Through collecting and analyzing the relevant literature of automated catwalk,and understanding the development of advanced drill pipe migration technology domestic and abroad.On the basis of summarizing foreign advanced drill pipe t and offshore drilling pipe transmission system,according to the actual situation of our country’s land drilling,design a set of automatic transport device for simultaneous transportation of three drill pipes.Considering the domestic onshore drilling conditions and the environment,as well as the working space and the actual operability,this drill pipe transport device is designed as an energy saving integrated cat road without lifting frame.In order to improve the efficiency of catwalk,design this catwalk of three slide,which can carry three pipes.In the conversion between the three slide rod,through a plurality of hydraulic cylinder control turnover mechanism to complete this process.The cat road set at 50 degrees to connect the ramp,and the upper end of the ramp length is adjustable,can adapt to different floor height.Through electro hydraulic to control the whole process.Including such a few aspects: First,summary current situation of drilling rod movement of land rig,brought out the research background and significance of this topic,and introduced the development status of land drilling machine of domestic and foreign.Overview of the research content and objectives of the project.Secondly,analyzed various types of domestic and foreign advanced model of the land drilling machine.Then,on this basis,combined with domestic land drilling rigs and the characteristics of domestic drilling conditions,designed the overall structure of the three pipe synchronous device migration.And built the overall structure model of the device by SolidWorks software.Analyzed the force of key parts of the device.Carry out the kinematics and dynamics analysis of the structure by using ADAMS software,to verify the feasibility of the design.Finite element analyzed of the stress of complex parts using ANSYS software.Finally,analyzed and designed drive system and hydraulic turning system of the device.Using solenoid valve to control the hydraulic circuit and working flow of the whole device.
