[0018] 1. First, install the device on the top of the outer end of the airborne system through the mounting seat. According to the required elevation angle of the radar antenna, operate the control panel to open the push rod switch. The output shaft of the push rod drives the push block to move on the strip plate, and the push block drives the connecting column to slide in the strip groove at the bottom of the slide seat. The connecting column drives the rack to slide in the limit groove at the top of the slide seat, so that the rack drives the main gear to rotate counterclockwise, and the main gear drives the linkage rod to rotate. Through the preset value of the push rod on the control panel, the horizontal movement distance of the rack is converted into the distance of the fixed-point rotation of the main gear, thereby controlling the rotation angle. Then the linkage rod drives the steering wheel to rotate the required angle through the plate column, and the linkage rod drives the display column to rotate. The steering angle can be observed from the scale value on the display column and the offset of the indicator groove. At the same time, the limit rod slides in the semi-ring groove, and the information value of the push rod is entered in advance through the control panel, and the moving distance of the rack driven by the output shaft of the push rod is converted into the fixed-point rotation distance of the main gear, thereby controlling the steering angle of the steering wheel, and then controlling the elevation angle of the support rod, which is safe and efficient.

[0019] 2. When the elevation angle is determined, the control panel is operated to turn on the motor switch. The output shaft of the motor drives the reducer to operate, the hollow shaft of the reducer drives the rotating shaft to rotate, the rotating shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the rotating rod to rotate, the rotating rod drives the fixed plate to rotate, the fixed plate drives the top seat to rotate, so that the top seat drives the steering mechanism to rotate, and then drives the radar antenna support rod to rotate. At this time, the annular column on the top of the support sleeve rotates in the limiting slideway of the sliding plate, thereby completing the steering work. When the steering wheel is reset or vibrated, the top end of the steering wheel is against the soft plate at the bottom of the buffer plate, and the buffer plate compresses the reset spring, thereby playing an anti-vibration buffering role.

[0020] The present invention can accurately steer the airborne radar control antenna by manipulating the controller to input control information to the push rod in advance and start the motor in the protection box. The operation is quick, safe and efficient, and the steering accuracy of the airborne radar is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

The hollow shaft of the reducer 122 drives the rotating shaft 123 to rotate. The rotating shaft 123 drives the first bevel gear 125 to rotate. The first bevel gear 125 drives the second bevel gear 126 to rotate. The second bevel gear 126 drives the rotating rod 127 to rotate. The rotating rod 127 drives the fixed plate 131 to rotate. The fixed plate 131 rotates. 31 drives the top seat 133 to rotate, so that the top seat 133 drives the steering mechanism 2 to rotate, and then drives the radar antenna support rod 212 to rotate. At this time, the annular column 1300 on the top of the support sleeve 130 rotates in the limiting slide 1320 of the sliding plate 132, thereby completing the steering work. When the steering wheel 200 is reset or vibrated, one end of the top of the steering wheel 200 is against the soft plate 2340 at the bottom of the buffer plate 234, and the buffer plate 234 compresses the reset spring 233, thereby playing an anti-vibration buffering role.
