Description

Technical Field

[0001] The utility model relates to the technical field of road crack detection, in particular to a road crack detection device. Background Art

[0002] Highway refers to public roads between cities, between urban and rural areas, and between villages that have been accepted and approved by the transportation authority and can be used for driving. It includes highways that have been built and approved by the transportation authority. It should also include highways that are designed in accordance with national highway engineering technical standards, approved by relevant national administrative departments and organized by the transportation authority for construction. Existing technology for road surface crack detection usually uses manual observation of ground cracks for filling.

[0003] However, the existing technology lacks the function of filling gaps according to the angles of road surface gaps. In actual use, the road surface will produce cracks of different sizes after long-term use. The lengths and widths of the cracks vary. The efficiency of filling the cracks by manual observation with the naked eye is low, and small cracks cannot be observed, resulting in the inability of the existing technology to quickly fill the road surface.

[0004] In addition, the existing technology lacks the function of shock-absorbing movement. In actual use, the uneven ground during road surface detection will cause the device to bump when moving, and the camera for detecting the road surface will not be able to stably detect cracks, resulting in the inability of the existing technology to perform buffering and shock absorption to stably detect cracks.
