A kind of follow-up control method of the rotating disk hunting gear of telescope of the present invention, be specially：In telescope main body with turning
Rotating disk hunting gear is set between disk, one-level rotating blade drive trigger switch, two are provided with step by step on rotating disk hunting gear
Level telescope main body stop motion switch, class C bearing motor produce super torque alarm trigger element, wherein, two grades are lost in one-level
Run in the case of effect, three-level is run in the case of being failed at two grades, so as to form safe operation guard method step by step.
As shown in Figure 1 to Figure 3, a kind of telescope for being provided with rotating disk hunting gear, including telescope main body 7, be arranged on
The rotating disk 6 of its underpart and by the two connection rotating disk hunting gear, wherein, rotating disk hunting gear include guide spring rope 5,
It is oriented to position switch 8, shutdown switch 9, rotating disk motor 11 and fixed cell.
Fixed cell is fixedly mounted on the bottom of orientation rotation mounting 1, while the upper end side of being also secured at of guide spring rope 5
The bottom of position swivel 1, and the mount point of the upper end of guide spring rope 5 is arranged at the upper end center position of fixed cell.
Fixed cell includes left fixed part 3, right fixed part 2 and several front and rear fixed beams 4, left fixed part 3, right fixation
It is symmetrical respectively on the inner side in portion 2 to be provided with two guiding position switch 8 and two shutdown switches 9, also, two guiding positions
Spacing distance between switch 8 is less than the spacing distance between two shutdown switches 9.Guide spring rope 5 is located in two guiding
In the intermediate space of position switch 8 and two shutdown switches 9.
Left fixed part 3, right fixed part 2 can be combined into top for two pieces of fixed plates being symmetrically obliquely installed, two pieces of fixed plates
The truncated rectangular pyramids structure that space is small, lower space is big.Two are oriented to the top that position switch 8 is respectively arranged at two pieces of fixed plates,
So that what is be spaced between ensureing two guiding position switch 8 is in small distance；Two shutdown switches 9 are respectively arranged at two pieces of fixations
The bottom of plate, so that what is be spaced between ensureing two shutdown switches 9 is in larger distance.I.e.：Two are oriented to position switch 8 and are symmetrically installed
The close fixed position of guide spring rope 5 both sides, two shutdown switches 9 are symmetrically mounted on two guiding position switch 8
Lower section and closer to outside.
The lower end of guide spring rope 5 is fixedly connected on rotating disk 6.Rotating disk 6 drives rotation, rotating disk by rotating disk motor 11
Motor 11 is three phase electric machine, and rotating disk 6 is made clockwise or counterclockwise under the driving of the three phase electric machine around telescope
Rotary motion.
Both sides slightly more remote position in the upper end fixed position of fixed guide spring rope 5, is fixedly installed two respectively
Cable wire 10 is protected, this two protection cable wires 10 are more slightly longer than guide spring rope 5, and fixed with the corresponding position of lower section rotating disk 6.
Guide spring rope 5 is with elastic string or other elasticity ropes that preferably material is made.
Set by said structure, the upper end of guide spring rope 5 will be moved in a plane, and fixed cell is with telescope
The motion of main body 7 and in orientation angles move；By the method being capped to fixed cell front-back, make 5, guide spring rope
Motion in one dimension can be done in the parallel surface of orientation rotation.Guide spring rope 5 is led because the rotation of telescope main body 7 can touch first
To position switch 8, rotating disk motor 11 turns according to the rotation direction that position switch determines rotating disk 6 that is oriented to for touching that side
The driven speed of disk-drive motor 11 is slightly larger than the maximum azimuth motion speed of telescope main body 7.
Embodiment 1：Telescope clockwise running status.
In real work, when telescope 7 rotary motion clockwise of main body, it is fixed in telescope main body 7
Guide spring rope 5 will be pull towards side, and guide spring rope 5 will touch the guiding position switch 8 of this side clockwise, driving first
Turntable control system picks up this signal and judges that rotating disk turns clockwise, driving rotating disk control system and then control rotating disk driving electricity
Machine 11 carrys out driving rotating disk 6 and carries out clockwise movement.
When above mechanism does not work, guide spring rope 5 will be drawn closer to outside, will touch stopping for this side
9 are only switched, the signal is directly connected with the power supply supply relay of control system, directly cuts off the power supply of rotating disk motor 11
Supply, and the power supply of the rotation control mechanism of cut-out telescope simultaneously.
Two steps all do not work more than, because protection cable wire 10 is somewhat more longer than guide spring rope 5, telescope main body
7 are further continued for rotating after one section of angle in orientation, and protection cable wire 10 pulls on rotating disk 6 and proceeds azimuth motion, such case
The azimuth-drive motor of lower telescope main body 7 can produce super torque alarm, and telescope main body 7 also can stop motion.
Embodiment 2：Telescope inverse clock running status.
When telescope 7 rotary motion counterclockwise of main body, guide spring rope 5 is by an angle delay, it will
Side counterclockwise is turned to from clockwise side, the orientation of telescope main body 7 continues to rotate, and guide spring rope 5 will be touched first
The guiding position switch 8 of this side counterclockwise is touched, driving rotating disk control system picks up this signal and judges rotating disk rotate counterclockwise,
Driving rotating disk control system and then control rotating disk motor 11 to carry out driving rotating disk 6 to carry out counterclockwise movement.
When above mechanism does not work, guide spring rope 5 will be drawn closer to outside, will touch it is counterclockwise this
The shutdown switch 9 of side, the signal is directly connected with the power supply supply relay of control system, directly cuts off rotating disk motor 11
Power supply supply, and simultaneously cut-out telescope rotation control mechanism power supply.
Two steps all do not work more than, because protection cable wire 10 is somewhat more longer than guide spring rope 5, telescope main body
7 are further continued for rotating after one section of angle in orientation, and protection cable wire 10 pulls on rotating disk 6 and proceeds azimuth motion, such case
The azimuth-drive motor of lower telescope main body 7 can produce super torque alarm, and telescope main body 7 also can stop motion.
In the present invention, by setting servo rotary device between telescope main body 7 and rotating disk 6, with safety, sensitive, simultaneously
Can very simple realization telescope main body 7 move while, rotating disk 6 below is also rotated with.Meanwhile, in servo rotary
Shutdown switch 9 and protection cable wire 10 are additionally provided with device, it can protect relative fortune between telescope main body 7 and rotating disk 6 step by step
Dynamic to be in controlled range, all these purposes are：The connection electricity of equipment in telescope main body 7 and the equipment on rotating disk 6
Cable and connector will not be dragged bad, and can ensure shorter cable connection.
