[0002] Highway inspection refers to the regular and irregular inspection and evaluation of highways and related facilities to ensure their safety, reliability and applicability. The highway inspection coring device is a device used to extract samples from highway pavement materials. It is mainly used for testing pavement structure and material properties. By coring, the composition, strength, and thickness characteristics of the pavement material can be analyzed, thereby providing data support for the design, maintenance and evaluation of the highway. The coring device includes a drill rig and a drill barrel. The drill barrel is used to collect samples extracted from the road surface and is usually made of stainless steel. The drill barrel is driven by electricity to rotate, and the drill bit coring is performed at the selected location.

[0003] However, the existing highway inspection and coring device is not perfect and still has certain defects:

The reinforcement block 15 moves up and down at one end of the embedded rod 10, which enhances the firmness of the lifting of the drill tube 8. After the coring is completed, as the drill tube 8 moves upward, one end of the multiple scraping strips 13 scrapes against the outer surface of the drill tube 8, which can scrape off the dirt attached to the outer surface of the drill tube 8. After starting the micro motor 28, it will drive the gear 29 connected to its output shaft to rotate, and then drive the straight rack 30 meshing with it to move forward, and the moving block 23 can move at one end of the fixed strip 22, which can also The storage cylinder 27 is driven to move forward. The storage cylinder 27 can store the core column inside the drill barrel 8. Through this structure, the core column can be effectively stored, which is convenient for subsequent coring. The card strip 26 is embedded in the interior of the accommodating frame 25, and then the two are engaged and connected. The storage cylinder 27 and the accommodating frame 25 can be limited and fixed, so that the storage cylinder 27 can be easily disassembled. The embedded rod 10 and the cleaning ring 12 are connected by the auxiliary block 11 to ensure the stability of the cleaning ring 12. Multiple scraping strips 13 are distributed at equal intervals to make them more fully contact with the outer surface of the drill barrel 8.
