Description

Technical Field

[0001] The utility model relates to the technical field of pavement construction, in particular to an electric core drill Background Art

[0002] At present, the pavement core drills are mainly gasoline engine core drills and electric core drills. The former has a large self-weight and is difficult to transfer the equipment, which is not conducive to the use of on-site operators. While the latter has a light self-weight, convenient equipment transfer and simple operation, and has gradually replaced the gasoline engine core drill in pavement coring. The structure of the electric core drill includes a bottom plate, a slide rail, a column, a slider, a motor box, a gearbox, a drill barrel, an operating rod, and a cooling water valve. The drill barrel is threadedly connected to the motor box and installed on the column, and a slide rail is provided on the column. The drill barrel can slide up and down on the slide rail. Its operation process is to first tighten the rotating bolt to fix the slider on the column, and then rotate the operating rod to make the drill barrel slowly descend along the guide rail. When the drill barrel contacts the road surface, turn on the power switch and at the same time open the cooling water valve to reduce the temperature of the drill barrel while coring; during the coring process of the existing pavement electric core drill, it is necessary to manually use the operating rod and rotate the operating rod while coring. At the same time, during coring, the electric core drill will also shift due to the ground impact force, affecting the coring efficiency and increasing the manual operation burden; and during coring, broken materials are likely to splash, posing a safety hazard; and with the change of the coring location, it is often necessary to manually lift the electric core drill, which is inconvenient for transportation and transfer.
