Structure Design of Permanent Magnetic Adsorption Wall-climbing Machine Chassis
The wall-climbing robot combines adsorption and on-wall motion to expand its working space and is in-creasingly used in various fields.Taking the steel wall as the application object,the functional requirements of the wall climbing operation are analyzed,and a mechanical chassis device with permanent magnet adsorption and wheel movement is designed.The force analysis of the mechanical chassis on the vertical wall is carried out to obtain its sta-ble working conditions.The mechanical chassis is mainly composed of walking wheels,transmission system and frame,it is driven by DC motors to achieve four-wheel differential.Three-dimensional modeling of the mechanical parts is carried out,and the assembly is completed,and the interference is checked.The mechanical properties of the main parts of the mechanical device are analyzed by the finite element method,and the mechanical properties of the main parts are verified.
