Problems solved by technology

[0002] At present, the installation method of the zigzag array antenna carried by the mobile platform is a spiral self-locking method. The zigzag array antenna is installed on the pitching device. The adjustment of the antenna pitch angle needs to be manually operated, and it is difficult to ensure three The pitch angle of the antenna is the same
Secondly, the pitching device of the existing pin-shaped array antenna mostly adopts a mechanical reducer, which has a large installation space and a large overall mass

Abstract

An automatic pitching device for a character-shaped array antenna. The three columns in the device are welded on the lower support plate at 120°, two angular contact bearings are installed in the bearing mounting holes on the lower support plate, and the bearing pressing block is fixed on the lower support plate. At the bottom of the seat plate, the DC motor is fixed on the bearing pressing block, and one end of the transmission shaft passes through the angular contact bearing and is connected with the power output shaft of the DC motor. The lower hinge bracket is set on the transmission shaft, the upper hinge bracket is set on the screw part of the transmission shaft, the positioning nut is installed on the screw rod of the transmission shaft, and the deep groove ball bearing is installed in the bearing installation hole on the upper support plate. The upper support plate is fixed on the column, the protective cover is fixed on the upper support plate, and the other end of the transmission shaft passes through the inner hole of the deep groove ball bearing and is connected with the rotary encoder arranged on the protective cover. The bearing retaining ring is installed on the transmission shaft, and is between the bottom of the bearing mounting hole of the upper support plate and the inner ring of the deep groove ball bearing.

Description

technical field [0001] The invention relates to a pitching device for a character-shaped array antenna, in particular to an automatic pitching device for a character-shaped array antenna carried by a mobile platform and capable of automatically adjusting the pitch angle. Background technique [0002] At present, the installation method of the zigzag array antenna carried by the mobile platform is a spiral self-locking method. The zigzag array antenna is installed on the pitching device. The adjustment of the antenna pitch angle needs to be manually operated, and it is difficult to ensure three The pitch angles of the antennas are the same. Secondly, the pitching device of the existing pin-shaped array antenna mostly adopts a mechanical reducer, which has a large installation space and a large overall mass. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide an automatic pitchi...
