Design and Simulation Analysis of Adaptive Pipeline Polishing Robot
Aiming at the problems of difficulty in detecting pipeline welds through oxide layers and low manual polishing efficiency,an adaptive pipeline outer wall polishing robot was designed,and its static stress and rotary polishing performance on the pipeline were studied.First,on the premise of meeting the polishing quality of the pipeline skin oxide layer,the feasibility of the plan is analyzed and the structural plan of the pipeline robot is proposed.The characteristics of its driving device and working device are analyzed.Then,SolidWorks was used to conduct three-dimensional modeling,and ANSYS Workbench was used to conduct static strength analysis of the robot and modal analysis of the lower angle grinder bracket to avoid fatigue damage caused by resonance effects.The analysis results show that the material strength of the robot meets the conditions and can seamlessly polish the oxide layer of the pipeline,but there are certain fluctuations in the pressure,speed and contact force of the carrier roller.
