Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a steel structure detection equipment for bridges. Background Art

[0002] Steel structure bridges have the advantages of fast construction speed, light weight and high rigidity. In order to ensure the quality of steel structure bridges, the steel beams under the bridge deck need to be inspected after the steel structure inspection equipment used for the bridge is completed.

[0003] The existing detection method is to use a manual handheld ultrasonic flaw detector to inspect the steel structure beams on both sides.

During the detection process, the impurities attached to the steel beams affect the detection accuracy of the ultrasonic flaw detector. For this reason, we propose a steel structure detection equipment for bridges. Utility Model Content
