Design And Analysis Of Telescopic Boom Type Drilling Rig Based On Drilling Platform

The telescopic arm drill plays an important role in the process of upper and lower shackle of the drill pipe or tubing on the land drilling platform.At home and abroad in this paper,through research on the hydraulic tongs and iron roughneck shackle technology of the status,on the shackle in the process of overall scheme,operation process,relevant technical requirements are analyzed,considering that in the process of buckled and shackle,tong head built-in clamping slip due to local radial force concentration,lead to the damage of the outer wall of pipe,sag and cracking phenomena,under standard of drill pipe API extrusion,utilization rate is low or cause drill pipe cause the accidents such as fracture,combined with the enterprise put forward on the shackle technical index,design a for drill pipe joint screw telescopic jib type iron roughneck,so that the iron roughneck clamping joint or collar location optimization of structural layout is reasonable,Improve the service life of drill pipe(or tubing),reduce the labor cost of overall oil drilling,and meet the API drill pipe standard and technical requirements provided by enterprises.The main contents of this paper are as follows:According to the overall technical requirements of the drilling platform,the related structural design of the device for unlocking the drill pipe joint is completed.Rotary bearing institutions choose common base,and design the scale of the displacement sensor under the arm,pliers clamping device and comes with a built-in clamping slip on clamp pliers head,can clamping of the different diameter of drill pipe joint,and the clamp head related parts clamping force and torque calculation and analysis,reduce wear and pressure on drill pipe damage,improve its service life,design a set of upper and lower clamp quadruple gap clasp collapse buckle reverse gear transmission mechanism and transmission mechanism,to improve the transmission efficiency by close to 30%,and eventually use Solid Works software to create the telescopic jib overall three-dimensional entity model of the iron roughneck.Design of hydraulic control system for iron drillers based on the function requirement of unlocking on drill pipe joints.To authors and raise the level of automation,for the purpose of optimizing the original hydraulic system,designs the hydraulic circuits including clamping hydraulic circuits,energy storage and reverse hydraulic circuit of a new hydraulic system,itsspecification of iron roughneck various functional units of work requirements,determine the system pressure of the iron roughneck,calculate and select the appropriate hydraulic components,in order to meet the button of drill pipe joint screw stick to collapse,and a series of process operation,single cycle on the drill pipe shackle total time saving,and can be combined with PLC for remote control,improve the work efficiency.Using ANSYS Workbench software key components of the iron roughneck rotary bearing base,built-in clamping slips,pliers body cage and telescopic arm forearm statics analysis,get the corresponding stress and displacement,test its structure size,at the same time meet the iron roughneck in the maximum load that is closely related to the intensity of and collapse buckle under transient state requirements,the key components to verify these force large on the rationality of structure size whether meet the iron roughneck shackle.Quad closed gear system kinematics model is established,based on Hertz contact theory applied in calculation of gear meshing contact force,the main tong studied the dynamic characteristics of gear transmission system,test and verify the performance of gear transmission smooth degree;The kinematics analysis of retractable arm iron drillers is carried out by using Solid Works kinematic MOTION module analysis.To simplify the Solid is in the Works of 3 d model into dynamics analysis software ADAMS,dynamics analysis,get the telescopic arm type iron roughneck migration in the process of displacement,velocity,stress curve,is telescopic arm type iron roughneck prototype test and provide a basis for the optimization design.
