Mobile robotized antenna, with chance of automatic unloading of the vehicle and putting into work position. The product is particularly appropriate for application in building small airports and auxiliary facilities in isolated regions. Due to its mobility, the antenna using robotized stand can be delivered easily and work on any terrains and at any weather conditions. The stand also has chance of automatic unloading of the vehicle and putting into work position.
Mechanical part of Mobile robotized antenna with phased antenna grid
Mobile robotized antenna with phased antenna grid is located in processed standard container 40’ with sizes length 12,036 m, width 2,350 m, height 2,690 m.
The side walls and the ceiling of the container should have the potential to be taken off or to be mobile frames, which do not obstruct the observance of the station.
1. Support platform, immobile, with potential for leveling.
The bottom of the container is used for support platform. There should be 4 support plates with screws for leveling. It is appropriate the support plates to be carried out sideways from the basis of the container for bigger stability.
2. Engine part: Electric motor, Reducer, Support bearing with sizes 9 1400 mm.
The support platform is mounted.
3. Rotating platform
The rotating platform is mounted on the support bearing.
It should be balanced for steady and even rotation with the speed given.
There are mounted to the Rotation platform:
– Bearing, bearing body, Feeder system;
– Cabinet for equipment with sizes length 1,5 m, width 1,5 m, height 2,0 m;
– Antenna constructive.
4. Antenna constructive –three separate constructive farms, in which the cells and components of the antenna system are installed.4.1. Bottom farm:-
The bottom farm to allow mounting antenna block with sizes length 8,5 m, width 0,5 m, height 2,1 m.
The bottom farm is mounted mobile on the rotating platform. There should be a chance of tilting in vertical surface from -10° to +15° via executive mechanism – screw couple with electro engine. In transport position it should be fixed immobile to the rotating platform mechanically.
4.2. Middle farm:
The middle farm to allow mounting of antenna block with sizes length 8,5 m, width 0,5 m, height 2,1 m.
The middle farm is mounted mobile to the upper end of the Bottom Farm.
In combat position the Middle farm is fixed immobile to the Bottom farm mechanically.
In transport position the Middle farm is tilted (folded) vertically with 90° to the Bottom farm by executive mechanism – screw couple with electrical engine. It is necessary to have auxiliary mechanical devices for fixing the middle farm immobile when transporting.
4.3. Upper farm:
The upper farm allows mounting antenna block with sizes length 4,0 m, width 0,5 m, height 0,66 m.
The upper farm is mounted mobile to the upper end of the Middle farm. In work position the Upper farm should have the chance to tilt in vertical plane from -10° to +15° via executive mechanism–screw couple with electric engine. With the same executive mechanism, the Upper farm is tilted (folded) vertically at 90° when putting into transport position. The total range of tilting of the Upper farm by vertical axis should be not less than -10° to +90°. It is necessary to have additional mechanical device for fixing the upper farm immobile when transporting.
In work position the Engine part rotates the mobile Rotating platform from 0° to 360° with speed 6 revolutions per minute or 12 revolutions per minute.
Electric engine, reducer and support bearing should be calculated for providing stable rotation (without thrusts) at wind velocity up to 30 m/s.
At turned off radar, the reducer should not be locked, but to allow free rotation of the rotating platform from the impact of the wind, at wind velocity 50 m/s. There should be taken into account that the surface of the antenna system is covered closely with radio translucent material.
In work position the entire Antenna constructive is tilted in a vertical plane from -10° to +15° from the executive mechanism for tilting the Bottom antenna. In order the Upper antenna to function right via its own executive mechanism, it compensates the change of the slope of the Antenna constructive.
The executive mechanism for tilting the Bottom farm should be calculated for the load it has by the Middle and Upper farm
