Abstract

The invention relates to the technical field of bridge detection, and discloses a crack detection device for double-layer supported bridges. The detection requires personnel to go under the bridge, which poses a threat to the personal safety of the detection personnel, and the efficiency is low, which is not convenient for practical use. It includes the bridge body and the mobile seat. The mobile seat is located above the bridge body. There is a lifting seat on the side, a rectangular hole is opened on one side of the lifting seat, a movable plate is provided on one side of the lifting seat, the movable plate runs through the rectangular hole, and the movable plate and the lifting seat are connected by moving out the movable mechanism; while the crack detector body rotates , The body of the crack detector slides relative to the rotating plate, which can detect different positions at the bottom of the bridge body in an all-round way. The operation steps are simple and convenient, and no personnel are required to go under the bridge for detection, which improves safety.

Description

technical field [0001] The invention belongs to the technical field of bridge detection, in particular to a crack detection device for double-layer supported bridges. Background technique [0002] Cracks on the surface of concrete bridges are mutations in the process of internal damage accumulation, and they are a concentrated expression of the dangerous degree of internal damage. Therefore, their information content is very large, and they are of key significance for predicting and harbingering bridge dangers. Therefore, it is necessary to analyze the cracks of bridges Detection, nip in the bud. [0003] In the prior art, the detection of cracks is mainly carried out by hand-held detectors, which is time-consuming and laborious. When detecting cracks on the bottom of the bridge, personnel need to go under the bridge, posing a threat to the personal safety of the detection personnel, and the efficiency is low, which is not convenient for practical use. Contents of the inve...
