Summary | The number of bridges in the Taiwan area is more than 26,000, wth the average age of bridges being 20. The work load of inspection and maintenance increases with bridge age. The current bridge inspector has the shortcomings of high cost, huge body and difficult operation. Additionally, high risk occurs in the inspection procedure in which a worker is placed underneath the bridge. This project, thus, develops a prototype bridge inspector carried by a vehicle to inspect bridge in a fast, economic and safe way. Based on the experience and results of the 2007 project for developing the prototype bridge inspector, this project further focuses on the modification and field test to become a practicable, convenient, safe bridge inspector. The sectional boom was analyzed following the standard of lifting machine safety inspecting, and the robot’s structure is analyzed using the finite element method. This project also examined the photograph quality under static and moving conditions. Field tests were taken on number one bridge in Fei-Tsui Reservoir, Penghu Sea-Crossing Bridge and Ta-Lio-Ken River embankment to validate the bridge inspector. |
