Technical Field

The invention relates to a steel truss bridge damage detection device, and belongs to the field of bridge engineering tools.

Background

In the auxiliary process of the steel truss bridge, damages such as paint falling, cracks, bolt loosening and the like can be generated due to environmental influence, material aging and the like. At present, the maintenance of the steel truss bridge usually adopts a manual maintenance method, namely, a maintenance worker takes a hanging basket fixed on T-shaped steel of a bridge deck to check, and records the specific position of a damaged part and the damage condition in a book. And the bridge maintenance platform consists of a plurality of standard section hanging baskets and can be adjusted randomly according to the required total width. The method is convenient, but still needs constructors to mount on the operation platform for manual inspection. But because the maintenance of the hanging basket has certain dangers, the method is only suitable for the steel truss bridge with smaller span and height; with the rapid development of bridge technology in China, the current overhaul facilities cannot meet the requirements of some large bridges; in addition, the manual maintenance efficiency is low, and conditions such as omission or misjudgment can be generated, so that large errors are caused.

Namely: the steel truss bridge damage detection device is needed at present, and can detect large bridges safely, efficiently and accurately.
