Description

Technical Field

[0001] This utility model relates to the field of bridge measurement technology, and in particular to a bridge crack measuring device. Background Technology

[0002] The crack depth tester utilizes the principle of acoustic diffraction. It is an intelligent non-destructive testing device that integrates testing, storage, and transmission. Its main purpose is to measure the depth of concrete cracks and the propagation speed of ultrasonic waves in concrete. Traditional measuring instruments require manually marking lines on the measuring surface to determine the distance, then manually applying coupling agent to the measuring surface, and finally using a probe to measure. This process is cumbersome, time-consuming, labor-intensive, and inefficient.

[0003] A bridge crack measuring device is mentioned in patent publication number CN211783191U. This patent utilizes a measuring plate mounted on a support column. Two movable plates on the measuring plate, along with a telescopic plate, enable rapid measurement of bridge cracks. Pointers on the two movable plates, along with scale lines, allow for precise and rapid detection of crack width, improving the device's efficiency. A limiting post on the limiting assembly, combined with a damping band, effectively limits the movable plates, enhancing measurement accuracy. The telescopic plate on the movable plate allows for the extension and retraction of movable plates, enabling the device to measure cracks of varying depths, further improving its efficiency. However, this patent also has the following problems:

[0004] The device has a fixed size during use, which makes it inconvenient for workers to transport and affects the efficiency of uniform speed. Therefore, there is a need to provide a bridge crack measuring device to solve the above problems. Utility Model Content
