气动爬缆机器人气压分析与试验

针对索径变化较大、表面情况恶劣的缆索，提出了一种采用铰链结构的气动蠕动式爬缆机男人结构模型，建立了该机器人气缸受力与高空气压损失等理论模型，并对样机研制实例进行了验算．研制了工程样机并在上海徐浦大桥上成功地进行了现场试验．仿真和试验表明，机器人气体压力损失与施工距离、高度、系统耗气量、气管倾斜度等成正比例非线性变化；机器人下降时速度较上升时均匀性好，能在斜拉桥缆索上安全、高效爬升．

Pressure Analyses and Experiments of a Pneumatic Cable-Climbing Robot

Aiming at the maintenance of the cables of variable diameters and rough surface to some extent in overall length, a mechanism model of a pneumatic worming cable climbing robot was put forward. Then, the mechanical models of the cylinder airloads and the pressure loss of the altitude air pipe were created and the engineering examples were simulated. Finally, an engineering prototype machine was developed and experiments were done on the Xupu Bridge. It indicated that the air pipe pressure loss of the robot was nonlinear and direct proportional to its operation distance, height, air consumption and gradient of the pipe; the robot could climb down at an evener velocity than that up, and could climb stay cables safely and efficiently.
