Machine for cutting concrete - has frame with drive motor for frame cutting head

摘要

The machine cuts vertical slots in hard materials such as concrete floors during construction of retaining and supporting walls the upper machine frame (1) is connected to the sealed bearing housing (2) and a minimum of two cutting cylinders (3) the cutting cylinders are driven by a motor and transmission gears and located above the upper machine frame (1) the sealed bearing housing (2) has a reamer attachment (4) underneath. The cutting cylinder (3) consists of a cylindrical roller casing (5) and is fixed to housing (G) with spacing pieces. Reamer teeth (6) on the reamer attachment (4) are controlled by the rotation of the cutting cylinders (3) and have a reaming position (R) and an emptying position (L). The reamer teeth have pivoted levers terminating with cutting tools (7) and the whole assembly is mounted on a pivoting spindle (9) attached to the cylindrical casing (5). Control levers (8) operate in conjunction with guide rails (10). The guide rails (10) produce a cutting curve in the cutting tools (7) which is transmitted along the length of the reamer teeth (6). In the middle section of this curve the floor rib recesses will be produced to the required full width. USE/ADVANTAGE - Cutting grooves in floors. Removal of materials prevents cutting mechanism from becoming trapped.
