摘    要:针对铁磁壁面缺陷检测的需求,设计一种融合超声检测功能的爬壁机器人。首先提出一种集耦合剂涂抹、超声检测和缺陷标记功能于一体的集成式检测机构,其次,设计一种含壁面打磨机构、耦合剂挤压机构的爬壁机器人,再次,针对机器人所处横向、竖直、悬壁3种工况,分析运动稳定性条件,包括吸附力条件和电机扭矩条件,为轮式磁吸附爬壁机器人的设计提供依据。研究结果表明:该机器人能够在铁磁壁面上实现移动和超声检测功能,包括壁面打磨、耦合剂涂抹、超声检测和缺陷标记。

Abstract: For ferromagnetic wall surface defect detection, a wall climbing robot fused the function of ultrasonic detection was designed. Firstly, an integrated detection mechanism integrating coupling agent coating, ultrasonic detection and defect marking was proposed. Secondly, a wall climbing robot with wall grinding mechanism and coupling agent extrusion mechanism was designed. Finally, the stability conditions including adsorption force conditions and motor torque conditions were analyzed for transverse, vertical and hanging working conditions of the robot, which provided a basis for the design of wall climbing robot based on wheeled magnetic adsorption. The results show that the robot can perform the function of motion and ultrasonic detection including wall grinding, coupling agent extrusion, ultrasonic detection and defect marking.
