The principle of the leveling machine is mainly to use laser control technology, closed-loop control technology and high-precision hydraulic system, and then use the computer to adjust the control, so that the scraper and vibration instrument of the leveling head can complete most of the procedures in the project, realizing one-time Through this, the computer can change the altitude standard ten times per second, and the number of vibrations per minute can reach about four thousand times.
Specifically, the leveling machine emits the horizontal line through the laser transmitter, the laser receiver receives the horizontal line, and transmits the signal to the control panel, and the operator adjusts the height and angle of the leveling head according to the prompts of the control panel, so that the ground reaches The specified levelness and verticality. High-precision hydraulic systems and computer-regulated controls play an important role in the leveling process. The high-precision hydraulic system can ensure the precise control of the height and angle of the scraper of the leveling machine head and the vibrating instrument, and the computer adjustment control can realize one-time pass to ensure the flatness and smoothness of the ground.
----Compared with the traditional manual leveling method, the leveling machine has the following advantages:
High precision, able to achieve high-precision levelness and verticality control;
The speed is fast, which can greatly improve the leveling efficiency;
Good quality, can ensure the flatness and smoothness of the ground;
The labor intensity is small, which can reduce the labor intensity of the operator.
Therefore, levelings are widely used in construction, roads, bridges and other fields.
