Document Type and Number:
WIPO Patent Application WO/2023/236237
Kind Code:
A1
Abstract:
A bridge detection device based on an impact echo audio frequency method having a wall climbing function and a detection method. The detection device comprises: a first vehicle body (1), comprising a first vehicle main body (11), a locomotion driving device (12), and a first rotor mechanism (13), a knocking assembly (14) being further provided on a power shaft (123) of the locomotion driving device (12); and a second vehicle body (2), comprising a second vehicle main body (21), and a sound insulation device (22), the sound insulation device (22) being rotatably connected to the second vehicle main body (21); the sound insulation device (22) comprises a sound insulation housing (23) and a knocking signal acquisition assembly (24); one end of the sound insulation device (22) is provided with a continuous track structure (25), and the other end is provided with a second rotor mechanism (26); the first vehicle body (1) is rotatably connected to the second vehicle body (2) by means of a rotating mechanism (3), and under the action of the rotating mechanism (3), the bridge detection device having the wall climbing function can climb on a wall surface having an included angle in a surface changing manner; and the bridge detection device based on the impact echo audio frequency method having the wall climbing function can climb over from the bridge bottom to a bridge pier and other areas to detect defects of the areas, and can also improve the detection efficiency.
