The invention discloses a leveling method based on four-point support and an electromechanical automatic leveling
system. In the leveling method, a symmetrical
diagonal lifting and leveling strategy is adopted, and the leveling purpose is achieved mainly by regulating the levelness of the ligatures among supporting points on
diagonal lines; and the leveling
system comprises a central processor, a
level sensor, a control keyboard, a display, four alternating-current
servo drivers and four supporting legs; and each supporting leg comprises a motor, a speed
reducer, a
ball screw and a base. The invention is particularly suitable for large-medium-sized
radar truck vehicle-mounted platforms, communication vehicles and various
engineering vehicles for
engineering machinery, the method has the advantages of high leveling efficiency, high leveling reliability and the like, and the leveling
system has the advantages of high leveling precision, high intelligent degree, high speed, strong
carrying capacity, good stability,
high transmission efficiency, suitability for severe environments and the like.
