초록 ▼

An automatic grading control device for finishing plastic concrete controls several different elongated, multi-section concrete finishing tools such as vibratory screeds or the like, with or without forms. Supporting skis facilitate sliding, winch driven movement of the device relative to the plastic concrete. Spaced apart and vertically upwardly extending towers are supported by the skis and disposed periodically along the length of the finishing tool. Each tower comprises a pair of elongated, spaced apart stanchions disposed on opposite sides of the tool that are braced with a rigid, adjustable upper strut. The strut extends between the stanchions and forms the top of the tower. Movable sleeves coaxially fitted to the stanchions are synchronized by rigid transverse bridges that extend between the sleeves above the tool. Hydraulic or pneumatic cylinders extending between the strut and the bridge raise and lower the tool thereby controlling level. The cylinders are controlled by a beacon laser and attendant sensors secured to the device. A control panel controls both the cylinders and winches. The winches move the device along the plastic concrete by spooling cables secured to a fixed point.

대표청구항 ▼

A laser operated automatic grade control device for finishing, surfacing or treating plastic concrete without forms, said device comprising: an elongated concrete finishing mechanism adapted to be deployed in physical contact with said concrete for treating same, said finishing mechanism having a longitudinal axis; at least two spaced apart, elongated skis oriented generally perpendicularly to said finishing mechanism for supporting the mechanism, said skis normally sliding below the surface of the concrete to be finished; a pair of stanchions extending upwardly from each of said skis, one stanchion disposed adjacent each side of said finishing mechanism; a slidable sleeve generally coaxially fitted about each of said stanchions; means for coupling said sleeves to said finishing mechanism; displacement means for raising and/or lowering said sleeves and thus said finishing mechanism; laser means maintained at a fixed elevation for providing a reference level; and, control means for controlling said displacement means responsive to said laser means, thereby leveling the finishing mechanism to provide a level concrete surface.
