Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering, and in particular to a bridge crack measuring device used in bridge engineering. Background Art

[0002] Reinforced concrete bridge structures have been subjected to vehicle loads for a long time. With the development of social economy, overclocking and overloading phenomena have become more and more prominent, and fatigue damage to beam structures has continued to accumulate. With the degradation of material and structural performance, concrete cracks are very likely to appear on the bottom or side of the bridge structure. Bridge cracks refer to cracks that appear on the surface or inside of the bridge structure under the action of various factors (such as load, temperature, humidity, material aging, etc.). These cracks may be difficult to see with the naked eye, but they are the direct cause of damage and destruction to the bridge structure, seriously affecting the overall performance and stability of the bridge, reducing its bearing capacity, and may accelerate structural aging and shorten its service life. The importance of crack measurement Crack measurement is an important part of bridge inspection and maintenance. Accurate crack parameter measurement (such as width, length, depth, etc.) can be used to evaluate the impact of cracks on the safety of the bridge structure, and then the cracks that appear on the bridge need to be measured through a bridge crack measurement device.

[0003] After the application was published, it became CN111551118B, a bridge crack measuring device and method for municipal bridge projects, which includes a horizontal cableway erected between adjacent bridge piers and a trolley sliding on the cableway, a rotating seat is horizontally rotated on the top wall of the trolley, two cameras are arranged side by side on the top wall of the rotating seat, and a linkage device for driving the two cameras to move away and closer synchronously is arranged on the rotating seat. The operator drives the rotating seat to rotate 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 to move away synchronously, so as to obtain a complete crack picture on the remote computer. The operator then calculates the maximum length of the crack on the collected picture and the actual proportion of the picture to obtain the actual length of the crack. The present invention has the effect of improving the efficiency of crack measurement. The invention extends the camera through a linkage device to photograph and measure the bottom of the bridge. However, cracks will not only appear on the bottom of the bridge body, but also on the side of the bridge body and the surface of the pier during the long-term use of the bridge. Therefore, the invention has a small measurement range for bridges, and the installation procedure before measurement is also cumbersome.

[0049] The driven wheel 87 and the driving wheel 88 are placed on both sides of the guardrail respectively. At this time, the driving motor can drive the screw rod to rotate. When the screw rod rotates, it can drive the driven wheel 87 to slide. When the driven wheel 87 slides to the side of the guardrail, it can clamp it. After the guardrail is clamped, the driving motor can drive the driving wheel 88 to rotate.
