Title:
CORE DRILL AND CORE DRILLING MACHINE FOR ASPHALT PAVEMENT
Document Type and Number:
WIPO Patent Application WO/2024/031871
Kind Code:
A1
Abstract:
The present invention relates to the technical field of core drilling machine equipment. Disclosed is a core drill and core drilling machine for an asphalt pavement, the core drill and core drilling machine comprising: a moving mechanism; a core drilling mechanism, which can be used for drilling a hole to extract a core; a plate sampling mechanism for sampling a pavement rutting plate; and a clamping mechanism for removing a rutting plate sample. The core drilling mechanism comprises a core drilling barrel, an inner wall of the core drilling barrel is provided with a movement groove, and the movement groove is slidably connected to an inner moving plate. By means of providing the core drilling mechanism and providing the movable inner moving plate in the core drilling mechanism, after a sample is removed from the ground, the inner moving plate can be moved so as to leave a gap relative to the inner wall of the core drilling barrel, so that the sample can be easily separated from the core drilling barrel; by means of providing the plate sampling mechanism and providing a cutting blade that has an adjustable spacing with a rotating electric motor, rutting plates with different specifications can be cut out; by means of providing the clamping mechanism, the rutting plate is removed from a pavement; and by means of the moving mechanism, the core drilling mechanism can be moved equidistantly at fixed points, thereby achieving automatic positioning and operation during core drilling and improving the core drilling efficiency.
