Abstract

The invention relates to a stopper device suitable for radar azimuth rotation exceeding ±180°, comprising: a stopper, which is fixed on an azimuth turntable; a transmission assembly includes a driving part and two driven parts, and the driving part is fixed to the turntable azimuth turntable. connection; the two driven parts are respectively mechanically driven with the driving part; the proximity block is fixed on the driving part; the two lead screw transmission mechanisms both include a lead screw part and a slider part, and the slider part is provided with a mechanical stop and a proximity switch; When the azimuth turntable rotates, it drives the driving part, the stop block and the proximity block to rotate synchronously, the two driven parts rotate relative to each other and drive the two lead screw parts to rotate relative to each other, and the proximity switch and mechanical stop on the slider part at the close angle avoid the The proximity block and the stop block are induced and collided, and the proximity switch and the mechanical stop on the far-angle slider part can be induced and collided with the proximity block and the stop block, respectively. The technical problem that the existing stop device cannot stop when the radar azimuth rotation exceeds ±180° is solved.

Description

technical field [0001] The invention relates to a stop device, in particular to a stop device suitable for radar azimuth rotation exceeding ±180°. Background technique [0002] The azimuth turntable is an important part of the radar system, and its main function is to drive the radar antenna to rotate with high precision according to the system requirements. When the azimuth rotation range is less than 360°, in order to prevent the software limit failure of the encoder failure, the azimuth turntable rotates beyond the limit position and damage the antenna or other parts, and to protect the radar antenna from collision damage with other parts, the azimuth turntable needs to be set stop device. [0003] At present, the azimuth turntable stop device is mainly used for azimuth rotation angles less than ±180°, which includes electrical stoppers and mechanical stoppers. Usually, the rotating part of the azimuth turntable is equipped with a proximity block and a stopper, and the ...
