Bridge surface crack detection device

Abstract

The invention provides a bridge surface crack detection device which comprises a detection vehicle, a connecting mechanism is arranged on the rear side of the detection vehicle, and the connecting mechanism is connected with image acquisition equipment and used for fixing the image acquisition equipment and controlling the horizontal height of the image acquisition equipment; positioning equipmentand central control equipment are further arranged in the detection vehicle; the central control equipment is connected with the image acquisition equipment, the connecting mechanism and the positioning equipment respectively; the image acquisition equipment sends an acquired bridge surface image to the central control equipment, the central control equipment performs crack identification detection according to the bridge surface image, and crack identification information and corresponding positioning information are sent to the cloud server when it is detected that cracks exist in the bridge surface image. The detection vehicle is controlled to travel to traverse the bridge pavement to automatically obtain the image of the bridge asphalt pavement surface, the obtained image is automatically and intelligently analyzed, crack information existing in the image is recognized and detected, the labor cost can be effectively reduced, and the accuracy of bridge surface crack detection is improved.

Description

technical field [0001] The invention relates to the technical field of bridge detection equipment, in particular to a bridge surface crack detection device. Background technique [0002] With the development of road construction in China, most bridges are currently paved with asphalt pavement to improve the driving quality of bridge pavement. [0003] However, the smoothness of the bridge surface, especially the smoothness of the bridge pavement, directly affects the quality of the bridge pavement. However, due to the long-term driving load and the influence of natural factors, cracks will appear on the asphalt pavement. If the cracks are not repaired in time, there will be potholes on the road surface, which will cause deeper damage to the asphalt pavement and reduce the quality of the bridge pavement. It will also affect driving safety. [0004] In the prior art, the detection of cracks on the bridge surface, especially the bridge asphalt pavement, is usually done manual...

However, due to the long-term driving load and the influence of natural factors, cracks will appear on the asphalt pavement. If the cracks are not repaired in time, there will be potholes on the road surface, which will cause deeper damage to the asphalt pavement and reduce the quality of the bridge pavement. It will also affect driving safety

[0004] In the prior art, the detection of cracks on the bridge surface, especially the bridge asphalt pavement, is usually done manually, which requires a lot of manpower. At the same time, manual detection is highly subjective and cannot meet the requirements of modern bridge surface cracks. testing needs
