Abstract

The invention discloses a bridge crack detecting device which comprises a support frame, a walking device and an image recording device, wherein the support frame can be detachably mounted on the bottom surface of a bridge; the image recording device is movably disposed on the support frame through the walking device; and the image recording device driven by the walking device is movable in at least one direction on the support frame. The image recording device performs image recording on the bottom surface of the bridge during the movement, and an inspector checks cracks at the bottom of thebridge according to the image recording. The device has the advantages of simple structure, convenient disassembly, high stability, accurate positioning and the like, and is capable of quickly and accurately detecting the cracks at the bottom of the bridge.

Description

technical field [0001] The invention relates to a bridge quality detection device, in particular to a bridge bottom crack detection device. Background technique [0002] With the construction of high-speed, heavy-duty railways and urban rail transit, the construction of prefabricated bridges is developing towards large spans, heavy tonnages and large loads, and the quality of bridges is particularly prominent. The traditional bridge quality supervision is based on the static load test, and the naked eye is used to observe the cracks in the test process. The observation method is relatively backward, which is easy to cause misjudgment and missed judgment, thus causing hidden dangers to the quality of the bridge. CN106645205A discloses a method and system for detecting cracks on the bottom surface of a UAV bridge. The UAV is used to obtain image data at the bottom of the bridge, and the cracks at the bottom of the bridge are searched for by analyzing the image data. This devi...
