A kind of satellite antenna pitching regulating device
Technical field
The present invention relates to the satellite antenna regulation technology, is a kind of satellite antenna pitching regulating device specifically.
Background technology
In the prior art, when adjusting satellite antenna to satelloid, the general turbine and worm that adopts makes up, worm screw breaks away from turbine under the normality, during work with antenna surface rotation to the precalculated position, lift that worm screw makes it and the turbine coupling, by a fixture worm screw is fixed, rotate the device that is connected with worm screw and finely tune, reach the star function.
General manual star antenna elevation angle adjusting device is comprised a turbine, turbine makes up with antenna surface and tightens together, and a through hole is arranged in the turbine in the heart, is fixed on the casing by axle; One worm screw, worm screw one end is bulb, is fixed on the casing, and the other end passes the circular hole on the slide block, is connected with the leader, forms a sub-assembly, and lifting screw is installed on the casing, and the turn lifting screw can make the worm screw combination rotate up and down around the bulb end.
The rotary antenna face lifts the worm screw combination to the precalculated position, makes it to be coupled with turbine, because the worm screw combination is lifted the position and not necessarily just is in couple state, need again the fine rotation antenna surface to make it and worm screw coupling, rotation and lifting screw rod, make it to withstand the worm screw combination, this moment, the screw rod adjustable height was difficult to control, and is too high, turbine and worm coupling tension, difficulty is rotated in the worm screw combination, and excessively low, the turbine and worm coupling gap is large, antenna surface is unstable, and wind resistance is poor.Little because of the lifting screw operating space again, operation inconvenience.
In sum, have in the prior art that the operating space is little, the fixing difficulty during turbine and worm coupling, service speed is slow, the mutual gap of turbine and worm large, antenna surface built on the sand, the problem such as desertification dirt poor performance.
Reason is as follows:
(1), because adopting the turbine and worm initial stage to be in disengaged position, worm screw is below turbine, worm screw one end is fixed under the normality, one end hangs down, lift worm screw during use, fixedly worm screw is adopted from the bottom up screw mandrel jacking system or eccentric wheel apparatus, because there is rolling disc the below, cause the operating space little, speed is slow during upper top.
(2), when lifting worm screw and making it to be coupled with turbine, because worm screw and turbine mutual alignment are not that just be in can couple state, can cause turbine and worm bump infringement turbine or worm screw.
(3), worm screw one end fixes an end and is in hang, when lifting the coupling of worm screw and turbine, the mutual centre-to-centre spacing of turbine and worm is unstable, misoperation can cause the mutual gap of turbine and worm large, antenna surface is unstable when having wind to carry, impact is to the star effect.
(4), turbine and worm makes up not in closed environment, when sand and dust are arranged, transmission difficulty in the time of can causing turbine and worm.
