Description
The utility model relates to the drive unit of a kind of synchronous satellite ground station.
The drive unit of existing satellite earth antenna has two big classes: a class is a hand gear, the TV programme of single satellite is normally watched in the orientation of hand control antenna and pitching, if watch multinational satellite television programming, must manually adjust or move antenna, not only require great effort but also inconvenient; Another kind of is Vidacare corp, the power of motor drives orientation and the pitching that screw mandrel removes steering antenna by the speed change gear of run-in index or fork dynamic formula, the same to the adjusting range of antenna and hand gear, can only be between 45 ° to 90 ° adjust among a small circle, because screw mandrel and chassis are a dead point when forwarding 90 ° to, must lay down the fixedly part of screw mandrel, the fulcrum of readjusting on the chassis just can forward 180 ° to.The dead point that exists in the prior art causes satellite earth antenna to fail to realize automatically to seek synchronous satellite.
The purpose of this utility model is at above-mentioned shortcoming, providing a kind of can make the pitching of satellite ground reception antenna from 0 °-90 °, the orientation realizes seeking manually, automatically the drive unit of the ground satellite station of synchronous satellite from+85 ° to-85 ° in overhead under the line 50 ° of-180 ° of scopes.
In order to achieve the above object, the drive unit of the utility model ground satellite station comprises orientation driving, pitching driving, locking device and orientation, pitching feedback device four parts, and they are realized by following measure:
Direction drive links to each other with antenna column chassis, the driving-chain that adopts satellite-type and direct conduction type to mix is formed gearbox with three grades of worm gears, after rotating speed of motor and power carried out three grades of decelerations and three grades of amplifications, drive the satellite spur gear around the pivot on antenna column chassis, and walk the epicycloid track along the sector that is fixed on this pivot and pass by 180 °, the promotion satellite earth antenna of realizing direction drive changes 180 °, has eliminated dead unit problem.
Pitching drives adopts the satellite-type driving-chain that second-stage worm gear pair, one-level screw mandrel and nut are formed gearbox, rotating speed of motor and power are carried out acting on the screw mandrel that links to each other with the parabola of antenna after three grades of decelerations and the three grades of amplifications, lift or spur antenna by screw mandrel, make the pitching of antenna and direction drive collaborative satelloid.
In order to watch image stabilization, is furnished with the mechanical locking device of forming by power input part, locking member and semi-circular track.Wherein power input part comprises power speed changing device and second level worm gear composition; Locking member is made up of forward and backward fixture block and the dynamometer spring that passes the forward lead screw at forward and backward fixture block middle part and be fixed on forward and backward fixture block upper end.This device links to each other with the antenna chassis, and half garden track links to each other with ground.When a needs antenna alignment satellite, the motor of controlling this device rotates, drive forward lead screw by power input part and import power to locking member, rotation by forward lead screw makes forward and backward fixture block away from the distance of track to regulation, locking device is in releasing orientation, and the antenna chassis can orbital motion; When antenna has arrived the angle of the satellite of looking for, control the motor counter-rotating of this device, forward lead screw will make forward and backward fixture block draw close to track, clamp track, thereby realize the purpose of locking satellite earth antenna.The power that locking member clamps track is limited by dynamometer spring, when forward and backward fixture block with the length of spring compressed certain-length, when promptly reaching certain clamping force, limit switch is cut off the electricity supply automatically, is stopped operating immediately by motor-driven forward lead screw.Satellite earth antenna is in locking state.
Spring can give the effect of elastic force to two fixture blocks in the clamping process of this device; Spring plays the balance clamping part when it clamps.Selected spring is by the size decision of clamping force.
All be furnished with automatically and the dual-use manual clutch with the first order worm gear in the gearbox of upper position and two devices of locking, be connected with automatic pole on it, automatic pole is screwed out or takes off and just carry out manual operation.The mechanism of pitching itself just can be automatically and manual two kinds of operations in addition.
In order to reflect the dynamic of each moment of satellite earth antenna, orientation and pitching all are provided with feedback and stopping means, and its structure is identical with action.The orientation feedback device is a dynamo-electric transducer of unifying to be set the position in relative rotation at antenna spindle and antenna chassis, the shell of transducer is rotated with the antenna chassis, the axle of transducer and the antenna spindle transfixion that connects together, when antenna and antenna spindle relatively rotate, then sensor outer housing and sensor axis also relatively rotate, therefore transducer is just exported digital signal and is reflected on the controller, and people just can find out the dynamically instant of satellite antenna.Routine techniques is adopted in electrical control, signals collecting and control thereof.
For spacing to antenna, on the pallet of feedback device+positions of 90 ° and-90 ° fix two limit switches, and pallet is to join with antenna column chassis, rushing piece above pallet links to each other with antenna spindle, the lead of limit switch is to be connected in the control circuit of motor, because antenna spindle is motionless, pallet and antenna spindle produce relative rotation, when antenna forward to+when 90 ° or-90 °, rush piece and travel switch is collided, cut off the electricity supply, motor stops operating immediately, satellite earth antenna also stops operating, and has guaranteed the safe operation of antenna.
