Apparatus and method for leveling the three-dimensional

摘要

Invention patent: b "apparatus and method for leveling a three-dimensional" d .A device and method for leveling to level three dimensionally curved surfaces includes a number of elongated alignment that is supported at opposite ends by a pair of rollers DAnd the fluid.The fluid cylinders are controlled to raise and lower the ends of the set of levelling independently of each other.By means of allowing the set of leveling create a three dimensionally curved surface as it passes over an area to be leveled.The control of one of the cylinders of fluid is based on a comparison of the measured position a first end of the assembly of leveling with a profile of the surface to be leveled it storesIn a memory of the computer.The measure of the position of the first end of the set of leveling is carried out by a tracking device that tracks the position of a target positioned at the first end of the assemblyLevelling and that determines the three-dimensional position of the target.A proximity sensor measures the position of the second end of the set of leveling from a surface, and emits a control signal which adjusts the height of the second end of the jointThe levelling to adhere to the surface.Alternatively,A second target positioned on the second end of the set of leveling is screened by a second tracking device to determine the three-dimensional position of the second end.The set of leveling preferably has a bow.A rotatable auger and a get hectic positioned adjacent and parallel to each other in a transverse the direction of movement of the set of leveling.The bow, the rotating auger and the strip vibration are all articulated around an axis parallel to its longitudinal direction.A controller pivu00f3 or inclination controls the slope of the bow, the rotating auger and get hectic to follow the inclination of the profile stored in the memory of the computer.
