Description
Technical Field
The invention belongs to the technical field of large instrument seats, and particularly relates to a novel phased array radar antenna seat and a radar antenna.
Background
An azimuth-elevation mount is a mechanism to support various instruments and equipment and allow azimuth-elevation movement about two axes perpendicular to each other. Azimuth motion, i.e., rotation about a vertical axis (azimuth axis), changes the azimuth of the supporting object; the pitch motion rotates about a horizontal axis (pitch axis), changing the pitch angle of the supporting object.
The traditional azimuth-pitching seat frame is composed of two rotating shafts which are perpendicular to each other and can be actively controlled, each rotating shaft is driven to rotate through a servo motor and a reduction gear train, the structure is simple, the control is easy, and the device is suitable for small and medium-sized supporting objects. However, if the supporting object is a large instrument, the force applied to the seat frame is greatly increased, and the structure becomes large and heavy to satisfy the supporting condition, thereby increasing the required driving power. The other improved azimuth-pitch seat frame adopts a parallel connection mode to drive two connecting rods to move along a circular track, so that large-scale equipment can be borne, but the rotating platform of the improved azimuth-pitch seat frame is mainly supported by an upright post positioned at the center, so that the requirement of the rotating platform on a negative pitch angle cannot be met. And when the size of the rotating platform and the range of the pitching angle are large, the size of the circular track is increased, which brings difficulty to processing and transportation, and the precision is difficult to guarantee.
Therefore, it is very important to solve the problems of heavy structure, large size and high driving power when the existing azimuth-elevation motion seat frame is used for large and heavy instruments and equipment.
