Description
Technical field
The utility model relates to a kind of cantilevered load bascule, and a kind of bascule of ship-board antenna pitch axis cantilevered load is especially provided.
Background technology
At mobile vehicle particularly in many application of boat-carrying communication technology of satellite, in, Large-scale satellite antenna is indispensable key equipment, but it is more difficult that the tracking of these antenna is controlled, especially wherein antenna pitching is controlled, this is mainly because the relative elevation axis of antenna of structure of satellite antenna is a kind of cantilever design, is a kind of non-orthostatic structure.The control swinging for the ease of antenna pitching direction at present, common way is to leave pitching rotation increase balancing weight in position far away, make the weight block of antenna center of gravity and counterweight reach equalising torque with respect to pitch axis, the control of antenna pitching is just easily accomplished like this.In actual applications, although by adopting the method for counterweight to realize the pitch control subsystem of antenna, this method exists many weak points, is first because antenna system number of spare parts is more, complicated structure, and the theory of counterweight is calculated very loaded down with trivial details.Next is to reach equalising torque effect, the gain in weight weight of piece, the gain in weight distance of piece and elevation axis of antenna, this is all reluctant to see concerning the design of satellite antenna, because gain in weight, piece weight means the increase of antenna overall weight, and the increase of the distance of weight block and elevation axis of antenna just means the increase of antenna volume.
Utility model content
The purpose of this utility model is to improve the weak point that prior art exists, and a kind of device of ship-board antenna pitch axis cantilevered load balance is provided, thereby realize, does not need counterweight just can realize the balance of satellite antenna pitching is controlled.
The purpose of this utility model is achieved in that
A ship-board antenna pitch axis cantilevered load bascule, it comprises a satellite antenna antenna-feedback system, supporting seat and scroll spring; On described antenna-feedback system, bearing is set, on described supporting seat, pitch axis is set, described antenna-feedback system is connected by described bearing and described pitch axis with supporting seat; Between described antenna-feedback system and described support seat, described scroll spring is installed, the installation direction of this scroll spring is the opposite direction of the cantilevered load of the spring force that produces while making to rotate because of this antenna-feedback system and generation.
Preferably, the installation direction of described scroll spring is: when the antenna surface of described antenna-feedback system is horizontal, in the raw, spring force is zero to this scroll spring; When this antenna surface departs from horizontal level, scroll spring, in rolling tightly state, starts to produce spring force; When this antenna surface is in vertical position, scroll spring is in rolling up to obtain the tightest state, and the spring force of generation is maximum.
Further, the spring force of described scroll spring is while swinging to upright position with this antenna surface from horizontal level, and the curve law that the gravity torque of antenna-feedback system changes is corresponding.
Preferably, between the two ends of described pitch axis and antenna-feedback system, a set of scroll spring is respectively installed, one end spring silk of this scroll spring is fixed on described pitch axis, and other end spring silk is fixed on described antenna-feedback system.
While starting pitching under the driving of antenna at elevation servo, gravity produces gravity torque with respect to pitch axis, simultaneously due to the effect generation of scroll spring and the spring force moment of gravity torque opposite direction, make antenna in equalising torque state, thereby antenna pitching is swung, control the easily realization that becomes.
The beneficial effect of the ship-board antenna pitch axis cantilevered load bascule that the utility model provides is: the pitching that does not need method by counterweight just can realize satellite antenna is controlled, both reduced the weight of antenna integral body, also reduced the volume of antenna integral body, and the stability of controlling also greatly strengthens.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ship-board antenna pitch axis cantilevered load bascule that provides of the utility model.
Fig. 1 a is the schematic diagram that shows the part amplification that scroll spring position is installed.
Fig. 2 is the structural representation of facing of the pitch axis of ship-board antenna shown in Fig. 1 cantilevered load bascule.
Embodiment
As shown in Fig. 1, Fig. 1 a and Fig. 2, the ship-board antenna pitch axis cantilevered load bascule that the utility model provides, comprises a satellite antenna antenna-feedback system 1, supporting seat 4 and two cover scroll springs 2.On antenna-feedback system 1, be fixedly installed bearing, be fixedly installed pitch axis 3 on supporting seat 4, antenna-feedback system 1 is connected by described bearing and described pitch axis with supporting seat 4, realizes antenna-feedback system 1 and with respect to the rotation of supporting seat 4, does pitching action.Two cover scroll springs 2 have been installed between antenna-feedback system 1 and support seat 4, and wherein one end of each scroll spring 2 and pitch axis 3 are fixed together, and the other end of scroll spring 2 and antenna-feedback system 1 are fixed together.The installation direction of this scroll spring is the opposite direction of the cantilevered load of the spring force that produces while making to rotate because of this antenna-feedback system and generation, be: when the antenna surface of described antenna-feedback system is horizontal, in the raw, spring force is zero to this scroll spring; When this antenna surface departs from horizontal level, scroll spring, in rolling tightly state, starts to produce spring force; When this antenna surface is in vertical position, scroll spring is in rolling up to obtain the tightest state, and the spring force of generation is maximum.
The antenna-feedback system of satellite antenna is when antenna surface is horizontal, the gravity direction of antenna-feedback system 1 is by elevation axis of antenna 3, the gravity torque producing is zero, now scroll spring 2 in the raw, spring force is zero, spring force moment is also zero, thereby the equalising torque state of antenna-feedback system 1 in gravity torque and spring force moment.
Under the driving at elevation servo of the antenna-feedback system of satellite antenna, start pitching, when antenna surface departs from horizontal level, the gravity direction of antenna-feedback system 1 also departs from elevation axis of antenna 3, thereby generation gravity torque, now scroll spring 2 is in tension, produce spring force, the spring force moment of generation and gravity torque opposite direction and equal and opposite in direction, thereby the equalising torque state of antenna-feedback system 1 in gravity torque and spring force moment.
The spring force of scroll spring 2 of the present utility model can be through optimal design, and while swinging to upright position according to antenna surface from horizontal level, the gravity torque change curve of antenna-feedback system designs.
