Problems solved by technology
[0004] The above existing technical solutions have the following defects: due to the different shapes of the cracks on the bridge, the length direction of some cracks will form a certain angle with the length direction of the bridge, and the existing detection device can only be along the width direction of the bridge. Expansion, and horizontal movement along the length of the bridge, resulting in a large overall length and incomplete shooting of crack images

Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0045] refer to figure 1 , is a bridge crack measurement device for municipal bridge engineering disclosed by the present invention, including a cableway 1 and a trolley 2. The cableway 1 is arranged along the length direction of the bridge and is located between adjacent piers below the bridge. The wall facing the adjacent bridge pier is respectively bolted and installed with a fixing frame. The cableway 1 is a steel cable, which is erected between the two fixing frames. Cableway 1 is provided with two groups horizontally and parallelly spaced along the width direction of the bridge, and arranged symmetrically on the center line of the bridge.
[0046] refer to figure 2 , the bottom of the trolley 2 is provided with an installation groove along its length direction, and the cableway 1 is placed in the installation groove. The trolley 2 is provided with ...

The invention relates to a bridge crack measurement device for municipal bridge engineering, which comprises a horizontal cableway erected between adjacent bridge piers and a trolley sliding on the cableway, a rotating seat is arranged on the top wall of the trolley for horizontal rotation, and the rotating seat Two cameras are arranged side by side on the top wall, and a linkage device for driving the two cameras away and close synchronously is arranged on the rotating seat. The operator rotates the rotating base so that the arrangement direction of the two cameras is roughly the same as the extension direction of the crack, and then drives the two cameras away from each other synchronously, so that the complete picture of the crack can be obtained on the remote computer, and then the operator will take the collected picture The actual length of the crack can be obtained by combining the maximum length of the crack on the image with the actual ratio of the picture, and the present invention has the effect of improving the efficiency of crack measurement.
Description
technical field [0001] The invention relates to the technical field of bridge construction engineering, in particular to a bridge crack measurement device and measurement method for municipal bridge engineering. Background technique [0002] Reinforced concrete bridge structures have been subjected to vehicle loads for a long time. With the development of society and economy, the phenomenon of overfrequency and overloading has become more and more prominent, and the fatigue damage of beam structures has continued to accumulate. Concrete cracks are prone to appear. Once concrete cracks appear, the corrosion channel will be opened, leading to the intrusion of corrosive medium, which will lead to corrosion fatigue or even fracture of the steel bar. Sudden and unpredictable, cracks in reinforced concrete bridge structures are a great threat to the safety of the structure itself. Therefore, real-time monitoring and perception of concrete cracks, timely repair of cracks, and str...
