Abstract: In order to improve the adsorption capacity of the wall climbing robot at arbitrary position in the steel pipe, a design scheme for novel non-contact permanent magnetic wall-climbing robot mechanism is proposed, starting with the structural design and combined with the structural characteristics of a certain type of steel pipe. Firstly, the design of permanent magnetic adsorption module is introduced in detail. Secondly, according to the geometric position change of the wall climbing robot in the steel pipe, the change of the adsorption force is calculated, and the static constraints in the limit case are analyzed. Finally, by simulation and field test, the wall climbing robot can realize reliable adsorption at arbitrary position in the steel pipe under large load.

Key words: wall-climbing robot, permanent magnetic adsorption mechanism, static analysis, simulation, reliability analysis
