Description

Technical Field

[0001] The present invention relates to the technical field of road crack repair, and more specifically, to a plateau road crack detection and repair device based on image recognition technology. Background Art

[0002] The plateau has a unique natural environment. The road crack repair equipment used in the plateau plays a vital role in highway maintenance. In the long-term use of the road surface, cracks are prone to appear due to factors such as vehicle rolling and weather changes. If these cracks are not repaired in time, they will gradually expand, affecting road conditions and even posing a threat to driving safety. Traditional road crack repair methods generally use manual filling methods, using manual handheld crack filling machines to fill road cracks, but this method is inefficient and the filling effect is difficult to guarantee. With the development of science and technology, road crack repair equipment has emerged. These devices usually use mechanized methods to efficiently and accurately complete the crack filling work.

[0003] There are many kinds of pavement crack repair equipment on the market, including asphalt caulking machines, crack repair machines, micro-crack treatment equipment, etc. These devices use different working principles to inject fillers (such as asphalt, geopolymer grouting materials, etc.) into cracks to repair the cracks. Among them, asphalt caulking machines have become one of the mainstream equipment for pavement crack repair due to their high efficiency and flexibility. However, traditional asphalt caulking machines usually still require manual participation, especially when facing complex and curved cracks on plateau roads. Manual operation can easily lead to hypoxia for workers, and it is impossible to use discharge heads of different calibers according to the width of the cracks. When the cracks are wide, the filling efficiency is limited, and when the cracks are narrow, the discharge head cannot be extended to fill, which is not convenient for actual use.

[0004] Therefore, in view of this, the inventor, based on his many years of rich experience in design, development and actual production in the relevant industry, has conducted research and improvements on the existing structures and deficiencies, and provided a plateau pavement crack detection and repair device based on image recognition technology, in order to achieve a more practical purpose.
