摘要: 为提高爬壁机器人在压力钢管内任意位置的吸附能力,从爬壁机器人结构设计入手,并结合某型压力钢管 结构特征,提出一种新型非接触永磁式爬壁机器人机构设计方案。 首先,对永磁式吸附模块设计给出了详 细介绍;其次,针对爬壁机器人在压力钢管内运动的几何位置变化,对吸附力变化情况进行计算,并对极限 情况下的静力约束条件进行分析;最后,经仿真及现场试验证明,该爬壁机器人可在大负载情况下实现压 力钢管内任意位置的可靠吸附。

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
