【摘要】：缆索是桥梁的重要构件,将机器人技术与无损检测技术结合改进,可开发出实用缆索检测机器人技术。为给桥梁缆索检测机器人的研发和应用提供指导,介绍既有缆索结构无损检测和机器人检测维护技术,重点介绍韩国2010年开始研发的2种桥梁缆索检测机器人的硬件和结构特点。利用目视检查和基于图像处理的检查、基于振动的索力测量、超声波检查、磁学方法和射线照相法等无损检测方法和功能模块,一些国家已经开发了一些用于管道、线路和缆索结构的检测机器人。2010年韩国制定了桥梁缆索检测机器人系统研究计划,主要开发了应用于斜拉桥和悬索桥的桥梁缆索检测机器人。这2种桥梁缆索检测机器人的硬件具有独特的功能,适应缆索直径范围较宽、荷载能力较大,能实现无线控制和通信传输,以及有效的机械电气自锁安全保障功能。试验结果表明,缆索检测机器人可以检测缆索内部钢丝缺陷,基于图像处理技术,可以感测3种不同类型缆索表面各种取向的裂纹状表面缺陷。
[Abstract]:Cable is an important component of bridge. Combining robot technology with nondestructive testing technology, a practical cable detection robot technology can be developed. In order to provide guidance for the development and application of bridge cable detection robot, this paper introduces the existing cable structure nondestructive testing and robot inspection and maintenance technology. The hardware and structure characteristics of two kinds of bridge cable detection robots which were developed in South Korea in 2010 are introduced in detail. Using non-destructive testing methods and functional modules such as visual inspection and image-based inspection, vibration based cable force measurement, ultrasonic inspection, magnetic methods and radiography, some countries have developed a number of pipeline applications. In 2010, South Korea established the research plan of bridge cable detection robot system, mainly developed the bridge cable detection robot used in cable-stayed bridge and suspension bridge. The hardware of these two kinds of bridge cable detection robots has unique functions, such as wide cable diameter range, large load capacity, wireless control and communication transmission, and effective safety guarantee function of mechanical and electrical self-locking. The experimental results show that the cable detection robot can detect the internal steel wire defects of the cable, and based on the image processing technology, it can detect the crack surface defects of three different types of cable surface with various orientations.
