EQUIPMENT FOR POLISHING BASIS, GRANILITE, GRANITE, MARBLE OR SIMILAR FLOORS.

Technical field

The utility model patent claimed herein discloses a polishing and finishing equipment for basement, granilite, granite, marble or the like applied to civil construction.

State of the art

The currently existing cement-based polishing, granilite, granite, marble or similar polishing and finishing equipment does not provide high productivity because they do not reach every surface to be worked, leaving a range of about 10 to 15 centimeters near the walls and columns, that need to be worked manually after the use of this equipment. These equipments do not yet have a pulley plane system, much less a weight-bearing structure to assist in polishing and finishing operations.

The state of the art points out some documents that refer to equipment for polishing cementitious bases, granilite among others, but all do not have the advantages provided by this equipment, among which we can mention documents PI9603302-9, MU8301165-0.

Document PI9603302-9 describes a surface polishing equipment which does not allow it to approach obstacles in the polishing operation, and the use of manual labor is required after the use of such equipment.

Document MU8301165-0 discloses a combustion burnishing polisher, where the entire powertrain has a protective support formed by cylindrical bars which also prevents the equipment from working near obstacles.

In this sense, the equipment has been developed, remedying such problems, which, mainly, does not require manual labor after the use of said equipment before its specially developed mechanism.

- The equipment now claimed does not require disassembly for drive adjustments (while existing ones require),

- The equipment uses coplanar belt (and belt) transmission system, while the others use belts in three or more planes;

- The equipment in question can rotate in any direction, either clockwise or counterclockwise, while the others rotate counterclockwise only;

- The equipment makes 700 square meters per journey 8 hours, while the others make 250 square meters namesma journey;

- The equipment allows working the floor up to 0.5 cm from the walls and columns, this halves the time required to perform a work, due to the need for manual finishing after the equipment work, as can be seen in figure 8, the distance between the fairing (2) and the rotating disc (4) is 5mm, that is half a centimeter, providing a perfect finish to the wall, eliminating additional labor;

- The whole set is prepared for coupling a high performance vacuum cleaner, providing zero pollution of the environment; and, - The equipment is driven by a trained operator who controls the direction to be followed by the equipment, obtaining the finish as per design specification.
