Abstract
The utility model discloses an antenna pedestal servo balance weight device characterized by being arranged on a bottom of an antenna pedestal X-axle box body mechanism; the balance weight device comprises a balance weight installation cylinder in a cylinder shape in a transverse arrangement; a balance block is arranged in the balance weight installation cylinder; two ends of the balance weight installation cylinder are respectively provided with bulkheads; and a middle part of the balance weight installation cylinder body is connected with the X-axle box body through a support. The balance weight device is simple in structure and small in occupation volume, can improve the disadvantage of big antenna driving moment, can simultaneously and conveniently increase or decrease balance weight through arranging the balance block and the bulkheads, is flexible in usage, and especially is suitable for being used in a servo tracking system of a miniature antenna.
Description
Technical field
The utility model relates to antenna servo tracking technique field, is specially the servo counter weight device of a kind of novel antenna pedestal.
Background technology
In small-bore antenna system, generally adopt X-Y type antenna pedestal effectively to solve the tracking problem that it's when top is past satellite, guarantee that the decorum is stable, receive signal reliably.X-Y type antenna pedestal has two rotating shafts, i.e. X-axis and Y-axis, and it is equivalent to the azimuth axis of a pitching type antenna pedestal in orientation is forwarded to horizontal level.When design X-Y type antenna pedestal, because the center of gravity of rotary antenna is not in rotating shaft, so produce bigger unbalanced moments in X-axis and Y-axis, be generally and make X-axis and Y-axis trim, need to add balance weight at the rotating part of diaxon, but the antenna pedestal volume that designs like this is big, heavy, two distance between axles big, moment of inertia is also big.So in the design of small-sized X-Y type antenna pedestal, the application abandons adding balance weight in Y-axis, only increase counterpoise in X-axis.Simultaneously adopt the motor that advances to add brake and the transmission of row amount decelerator during Driving Scheme, efficiently solve the self-locking problem of optional position antenna.
Summary of the invention
Technical purpose of the present utility model provides a kind of new antenna holder structure, utilizes the space to increase bascule in the antenna pedestal X-axis, improves the antenna servo tracking performance.
The technical solution of the utility model is:
The servo counter weight device of a kind of antenna pedestal, it is characterized in that, be arranged on the bottom of antenna pedestal X-axis chair mechanisms, described counter weight device comprises the counterweight installation tube that is cylinder type of horizontally set, described counterweight is installed in the tube and is provided with balance weight, counterweight is installed the tube two ends and is respectively equipped with plug, and described counterweight is installed tube stack shell middle part and is connected with the X-axis casing by support.Plug is in order to seal counterweight tube to be installed, stationary magazine creel inner equilibrium piece and arranging.Support is to increase the arm of force in order to increase balance weight to the rotation distance of X-axis, but because the antenna pedestal space is less, the arm of force is unsuitable long during making, and certain rigidity of support will be arranged.
Described counterweight is installed in the tube and is provided with a plurality of balance weights, can increase or reduce the weight of counterweight easily to adapt to the installation of Different Weight volume antenna.
As preferably, described balance weight can adopt lead, and to increase the weight of counterweight in limited space, it is excessive to be unlikely to volume again simultaneously.
Described X-axis casing is fitted on the base support that a head is down " ㄇ " type, X-axis casing and described counter weight device are positioned at down in the recess space between " ㄇ " type structure two stands arm, and the X-axis casing is fastened on down on the two stands arm of " ㄇ " type structure by the rotating shaft at two ends.
Described antenna pedestal is X-Y type antenna pedestal.
The utility model utilizes the space to increase bascule in the antenna pedestal X-axis, has improved the antenna servo tracking performance.The utlity model has compact conformation, manufacture craft is simple, volume is little, the closely spaced advantage of diaxon, and properties of product are reliable, Installation and Debugging are convenient, have again simultaneously and improve the big effect of antenna pedestal driving moment, the required power of motor is specially adapted to the small size antenna servo tracking system when having reduced the sky line following.

Embodiment
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with the drawings and the specific embodiments the utility model is done further introduction.
As shown in the figure, the servo counter weight device of a kind of X-Y type antenna pedestal, be arranged on the bottom of antenna pedestal X-axis chair mechanisms 1, described counter weight device comprises the counterweight installation tube 2 of horizontally set, counterweight is installed tube 2 interpolations for balancing weight the space is provided, and handling position and length are no more than the support distances of X-axis, for the rotary space that does not increase the X-axis casing can be made circular cylinder, processing is simple, and good looking appearance.
Described counterweight is installed the balance lead 3 that is provided with some round pies in the tube 2, and counterweight is installed tube 2 two ends and is respectively equipped with plug 4, and described counterweight is installed tube stack shell middle part and is connected with the X-axis casing by support 5.Plug 4 is to adjust to fix behind the balance weight of counterweight usedly, and balancing weight can dissolve with lead to be made cylindrically, is divided into some again.
Described X-axis casing is fitted on the base support that a head is down " ㄇ " type, as shown in Figure 1, X-axis casing and described counter weight device are positioned at down in the recess space between " ㄇ " type structure 6 two stands arms, and the X-axis casing is fastened on down on the two stands arm of " ㄇ " type structure 6 by the rotating shaft at two ends.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
