Embodiment

[0024] A concrete crack detection device at the bottom of a bridge 1 includes a driving drum 2 , a driven drum 3 , a pulley block, a detection component 10 and a traction device 12 .

[0025] Both the driving reel 2 and the driven reel 3 are arranged on the upper end surface of the bridge 1 , and the driving reel 2 is wound with a traction driving belt 4 , and it can wind the traction driving belt 4 . The traction driving belt 4 goes around the pulley block and is wound on the driven reel 3 .

[0026] The pulley block includes two elongated steel plates 5, an adjustment slide 6, two first pulleys 7 and two second pulleys 8. The extended steel plate 5 is fixedly arranged on the side of the bridge 1, the lower end of the extended steel plate 5 protrudes below the bridge 1, the adjustment slide seat 6 is horizontally slid and arranged on the left extended steel plate 5, and the two first pulleys 7 are vertically arranged on the On the adjustment slide 6, two second pulleys 8 are...

Abstract

The invention relates to the field of bridge detection, and particularly discloses a bridge bottom concrete crack detection device which comprises a driving winding drum, a driven winding drum, a pulley block and a detection component, a traction driving belt is wound on the driving winding drum, bypasses the pulley block and is wound on the driven winding drum, and the detection component is arranged on the traction driving belt. The detection part is provided with a camera device, and the camera device is aligned with the bottom of the bridge. The invention aims to solve the technical problem of how to detect concrete cracks at the bottom of a bridge.

Description

technical field [0001] The invention relates to the field of bridge detection, and specifically discloses a concrete crack detection device at the bottom of a bridge. Background technique [0002] Concrete crack detection is one of the important items of bridge detection. There are various detection methods such as ultrasonic detection and naked eye detection in the existing technology. Ultrasonic detection can detect the internal structure of concrete, and the detection is more comprehensive. Ultrasonic detection works very well in the laboratory. When used in actual situations, the outdoor noise is relatively large, including vehicles, pedestrians, wind, rivers, etc. These noises cannot be completely isolated and eliminated, and vibrations cannot be completely avoided. Therefore, the accuracy of the results obtained by ultrasonic testing in practice is very poor, and there is no reference at all. Although the efficiency of human eye detection is low, the detection accuracy...
