Description
Technical field
The present invention relates to big medium caliber reflector antenna technical fields, particularly relate to a kind of sky for reflector antenna
Between constitutional balance refitting set.
Background technique
Reflector antenna used in the fields such as communication, observing and controlling and radio astronomy, will have pitching function, also,
Pitch axis will be overlapped with the center of gravity of pitch rotation part, so that pitch rotation inertia and pitching wind moment are smaller.But it was designing
Cheng Zhong, the position of centre of gravity of pitch rotation part are not generally possible to accomplish and pitching overlapping of axles.
In order to reduce the load of driving device, reduce servo error, it usually needs balancing device.Traditional method is will to put down
Weight block is mounted in the cabinet of elevation mount or is placed on counterweight block the two sides of pitching gear, makes pitch rotation part
Reach static balance, to reduce unbalanced moments, mitigates the load of motor.Although the structure type of this balance weight can make to reflect
Surface antenna reaches equilibrium state, but has the following deficiencies:
(1) weight weight.Due to being influenced by pitching cabinet or gear space size, the distance between pitch axis and counterweight block can become
It is short, cause the arm of force to reduce, so that counterweight block weight increases, while increasing the weight of pitch rotation part, therefore pitching turns
The weight of dynamic inertia, driving device and entire antenna system is also with increase.
(2) rigidity is low.Since pitching gear is that planar structure can additionally increase tooth when clump weight to be placed on above
The load of wheel, reduces the rigidity of gear, to influence the precision of transmission system.
(3) it is not easy to adjust.The clump weight that conventional balanced refitting is set is steel plate or stereotype, is connected by bolt and cabinet or gear
It connects, in the installation and debugging process of antenna, is not easy to realize continuous adjustment.
A kind of X-Y type day is disclosed in the Chinese patent " antenna pedestal servo counter weight device " that notification number is CN203232950U
The counter weight device of line seat, although this method trim X-direction, has the disadvantage that
(1) it is only applicable to X-Y type mounting.The utility model patent is only applicable to the X-Y type mounting of small-bore reflector antenna, right
It is then not suitable in widely used A-E type mounting, the reflector antenna of especially big medium caliber.
(2) X-axis is only balanced.The utility model patent, which only refers to, balances X-direction, abandons and increases in Y direction
The method of balance weight.
(3) weight weight.Due to being limited by two support arm sizes, clump weight is closer apart from X-axis, in order to reach balance, is needed
Increase clump weight weight, results in the increase of system weight.
It is disclosed in the Chinese patent " Self-weight-balancing type antenna stand " that notification number is CN2870200U a kind of for being mounted on
Antenna holder on building；" included counterweight antidumping formula roof beautifies day to the Chinese patent that notification number is CN202111872U
Line base station " in disclose a kind of antenna for base station housing structure with concrete balancing weight.Although the two methods are suitable for solid
Fixed pattern antenna, but for having for the reflector antenna that can do pitching movement function, it has the disadvantage that
(1) it can not be attached with reflector antenna.Method provided by both the above utility model patent is only applicable to base station
Equal flagpole antennas form, can not be attached or match with reflector antenna.
(2) it is not suitable for the reflector antenna to make rotating motion.Reflector antenna will do pitching movement at work, above-mentioned
The weight body referred in method provided by two kinds of utility model patents passes through bracket or pedestal is connected with building, can not
It realizes pitching movement, therefore is not suitable for the reflector antenna to make rotating motion.
