METHOD FOR FOLDING DISH FEED AND HYDROMECHANICAL DEVICE THEREFOR

摘要

1. A method for folding a chassis-mounted dish feed of a radar station comprising positioning the dish feed for transportation, characterized in that folding of the antenna feed together with supporting tube is performed by rotatably displacing of the dish feed in three planes relative to the plane of a dish reflector by means of a hydromechanical device, kinematically connected to the dish base and to displaceable feed, providing first turning of the dish feed together with the supporting tube relative its longitudinal axis by 60 degree +-3 degree , then turning of the dish feed together with the supporting tube relative its vertical axis by 45 degree +-4.5 degree , and longitudinal displacement of the dish feed together with the supporting tube into the folding zone for transportation position being within railroad clearance. 2. A hydromechanical device for folding a chassis-mounted dish feed of a radar station comprising positioning the dish feed for transportation, characterized in that the device comprises three cylinders connected to a controllable pressure source and to a common drain collector via a quick release coupling, wherein the dish feed together with the supporting tube is connected to a horizontal beam of a carrying T-shaped holder via a bearing unit, the holder is secured by its vertical column to the dish base via said bearing unit, a hydrocylinder for turning relative to the longitudinal axis is rigidly fixed by its base to the dish base, and by its rod is kinematically connected to the disconnectable butt of the feed supporting tube, a hydrocylinder for turning relative to the vertical axis is rigidly fixed by its base to the dish base, and by its rod is kinematically connected to the disconnectable butt of the feed supporting tube, a hydrocylinder of longitudinal displacement is rigidly connected to the antenna system base and by its rod to the casing of the dish feed supporting tube.
