Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
As shown in figs. 1 to 6, the present embodiment includes pedestal 1, transmitting extension set 2, receives extension set 3, transmitting backrest 4, receives backrest
5, emit actuator 6, receive actuator 7, orientation actuator 8, servo-control system 9 and liquid cooling unit 10；The transmitting backrest 4
It is separately positioned on the both ends of pedestal 1 with reception backrest 5, is separately installed with transmitting front in the transmitting backrest 4 and reception backrest 5
11 are separately mounted to correspond to and emit backrest 4 and receive in backrest 5 simultaneously with reception front 12, the transmitting extension set 2 and reception extension set 3
It is communicated with corresponding transmitting front 11 and the host computer for receiving front 12, the host computer is according to corresponding front measuring signal pair
Servo-control system 9 issues signal, and the servo-control system 9 passes through transmitting actuator 6, reception actuator 7 and orientation driving
Part 8 tracks target, realizes the measurement to target position, and the transmitting actuator 6 and reception actuator 7 are respectively used to driving transmitting
Backrest 4 and the pitching for receiving backrest 5, the orientation actuator 8 is for driving entire pedestal 1 to rotate.Using Integration Design, liquid
Cold group 10, servo-control system 9, transmitting extension set 2 and reception extension set 3 are integrated in pedestal 1 and corresponding backrest respectively, save and set
Standby space.The transmitting extension set 2 and the bottom for receiving extension set 3 are respectively provided with the clump weight 13 of counterpoise.
The transmitting actuator 6, reception actuator 7, orientation actuator 8 are electric-machine directly-driven transmission, transmission shaft and motor
It is connected by positive coupling.Using two-dimentional direct-drive type transmission chain, transmission chain component is dramatically reduced, reduces transmission
Loss of accuracy.
The transmitting actuator 6 is fixedly connected with the transmission shaft for receiving actuator 7 by rigid sleeve 14.Eliminate two sides electricity
Machine rotates asynchronous error, so that manufacturing, being easier for installation.
The both sides of the face of the transmitting actuator 6 and the transmission shaft for receiving actuator 7 are separately installed with angular transducer 15,
The transmission shaft end surface of the orientation actuator 8 is equipped with angular transducer 15.Angle measurement element and output end executive component is direct-connected,
Guarantee the accuracy of angle measurement accuracy to the maximum extent.Guarantee the accuracy of angle measurement accuracy in conjunction with the disappear poor effect of angular transducer 15.
The bottom of the transmission shaft of the orientation actuator 8 is connected with conducting slip ring 16.Conducting slip ring 16 realizes sound optical electrical
Switching between cable.
The transmitting backrest 4 and reception backrest 5 are truss structure.By between the double fronts of rigidity guarantee of backrest truss structure
The depth of parallelism.
The transmitting backrest 4 is equipped with the adjustment gasket 17 that front is corresponded to for location and installation with the top for receiving backrest 5.It is logical
Structure fine tuning is crossed, the depth of parallelism of double fronts is further increased.
Trapezoidal groove 18 is offered on the adjustment gasket 17, corresponding front bottom is provided with trapezoid boss 19, the ladder
Shape boss 19 is caught in the trapezoidal groove 18.

Adjusting pad piece 17 and front can be made to position by the wedging effect of trapezoidal groove 18 and trapezoidal raised two waist, then made
Gasket 17 and backrest are adjusted by precision-machined surface cooperation plus cylinder finger setting, when the depth of parallelism between two fronts occurs in small range
When deviation, it may be unnecessary to the mounting surface in backrest is processed, and is only needed to the adjustment plane machining engaged therewith of gasket 17,
Large-sized structural parts are not only avoided to repeat influence of the dismounting to precision, moreover it is possible to greatly save assembly and disassembly workload, shorten adjustment time.
Emit front 11 and receive front 12 be the large-sized structural parts having a size of 2.5m, if because measurement accuracy not enough and
It modifies, whole knot component requires to scrap, and loss is too big, and adjustment gasket 17 is used to carry out minor adjustment, can basis
Adjustment gasket 17 appropriate is replaced in abrasion or required precision, reduces loss.
In order to guarantee pitching, azimuth axle precision, the present invention has abandoned the form of traditional motor reducer combination transmission,
Instead the driving form that motor directly drives output shaft, the transmission generated due to retarder backlash is avoided in this way
Error.In view of between motor and transmission shaft by key transmission the material of axis can be removed, influence the rigidity of axis, thus
It is connected between motor and transmission shaft using positive coupling, also, in order to guarantee the transmitting actuator 6 of pitching shafting, receive and drive
The synchronizing motors of moving part 7 realize Synchronous Transmission in two transmission between centers connection rigid sleeves 14.Pitching shafting is using double angles
It spends sensor 15 to arrange, be connected respectively with two transmission shaft end surfaces, the angle position that can directly measure output can also disappear difference
Measurement accuracy is improved, azimuth axle angular transducer 15 and orientation axial end are connected, and since space limits, azimuth axle can not be adopted
Arrange that, in order to also generate the poor effect that disappears in azimuth axle, the angular transducer 15 of azimuth axle is adopted with double angle sensor 15
Arrange that two reading heads are arranged at 180 ° with one division ruler, double-reading head.
Antenna mount system of the invention use Integration Design, liquid cooling unit 10, servo control box, extension set respectively with pedestal
1, backrest is integrated, and servo control box and extension set are even more to be closed in internal system, does not influence overall beautiful, and saves space.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
