Abstract

The invention belongs to the technical field of concrete structure nondestructive testing, and particularly relates to a road and bridge nondestructive testing detection device which comprises a mounting box, two arc-shaped plates, a supporting adjusting assembly, a track adjusting assembly, a nondestructive testing part and a supporting driving assembly. The two arc-shaped plates are symmetrically arranged on the mounting box; the supporting and adjusting assembly is arranged on the mounting box, connected with the two arc-shaped plates and used for supporting the two arc-shaped plates and adjusting the included angle. The track adjusting assemblies are symmetrically arranged on the two arc-shaped plates and are used for adjusting the movement track of the device along the outer side of the to-be-detected stand column; the nondestructive testing part is arranged on the front side of the mounting box. The device is reasonable in design, compact in overall structure and flexible to control, thoroughly solves the technical problems of low efficiency, high dangerousness, inconvenience in data recording and the like of traditional manual climbing detection, and remarkably improves the automation level and operation safety of road and bridge stand column nondestructive testing.
