APARATUS FOR CUTTING FREE COVERS IN COATING, E.G. ASPHALT COATING |
摘要 |
An apparatus (2) for cutting free cover well curb in coating (4), for instance asphalt coating (10), comprising a basis part (16) pivotally fastened around a vertical centre axis in proportion to a support plate (4), which is adapted to be placed centred on a cover (6), a in proportion to the basis part (16) and said centre axis radial adjustably fastened bracket part (18), a in proportion to the bracket part level adjustably fastened support bracket (26) for a rotating cutting or mill unit (42), preferably driven by an internal combustion engine (38), and a turning motor (54) inserted between the basis part and the support plate. Hereby an apparatus is obtained, which by simple provisions is able to automatically cut free a cover well curb. The apparatus is just placed in the middle of the cover, whereafter the driving motor preferably in the shape of a combustion engine is started. By means of a turning motor the quick-rotating cutting or mill blade is turned round along the edge of the cover well curb, while the cutting or mill unit slowly is moved downwards, until the web curb is cut free from the coating. |
