Abstract
The invention discloses an azimuth transmission mechanism and dome main structure integrated follow-up dome for a space observation instrument. The hemispherical or super-hemispherical dome is arranged above an observation chamber of the space observation instrument, the top of the observation chamber is provided with a dome guide rail, travelling rollers are arranged below a chassis of the dome, and the travelling rollers are arranged on the dome guide rail and can move along the dome guide rail; and the middle of the dome is provided with a slit, and a skylight is arranged on the slit. The dome is characterized in that: the number of the travelling roller is an even number of more than 4, wherein one half is power wheels, the other half is driven wheels, and the power wheels and the driven wheels are placed at intervals; and each power wheel is provided with a power mechanism. A brand-new dome azimuth driving mode is adopted in the dome, a use space in the dome chamber is increased compared with the conventional follow-up dome with the same size, and the operation of the dome is more stable by multi-point drive.
Description
Technical field
The present invention relates to a kind of dome that is used for observation instrument protection in empty day, be specifically related to a kind of being used for the orientation transmission mechanism of observation instrument (for example astronomical telescope) protection in empty day and the servo-actuated dome of dome main structure one.
Background technology
Present servo-actuated dome usually adopt one can the orientation rotation hemisphere or the sphere structure of super hemisphere, the slit that a width does not wait is opened in the centre, is furnished with removable top cover (skylight) above, during observation, the skylight is opened.On the ground worm speed reducer is installed in the dome, the reductor shaft is provided with sprocket wheel (or gear) and stirs the chain (or internal gear) that is fixed on dome below (dome chassis) dome is rotated with telescope, with the observation target in district on the same day not.
When higher or diameter is big when the dome rotating speed, because dome deadweight big (the dome deadweight as 6 rice diameters is about 10 tons), when telescopical orientation rotating speed acquires a certain degree (be higher than 6 the degree/s), guarantee that dome and telescope are synchronous, need be furnished with powerful motor and corresponding controller, with high costs, and it is bigger that azimuth mechanism takies the dome inner volume, reduce effective usable floor area, the factor that takies the dome interior space because of the orientation transmission mechanism has to strengthen the dome diameter sometimes, guaranteeing the use of observation instrument, thereby increased cost.
Summary of the invention
The purpose of this invention is to provide a kind of being used for, be used for the protection of (comprising that astronomical telescope and other are to empty day observation instrument) of empty day observation instrument to the orientation transmission mechanism of observation instrument protection in empty day and the servo-actuated dome of dome main structure one.This dome adopts a kind of brand new dome type of drive, its orientation transmission mechanism is overlapped turbine deceleration mechanism by one of routine change the driving of 3 points (or multiple spot) into, make operation more steady, dome is stressed more even, effectively increase the service life, and its power section (containing the deceleration transmission part) is all placed inside, dome chassis, can not take usage space in the dome.
The scheme of finishing the foregoing invention task is: a kind of orientation transmission mechanism and dome main structure one servo-actuated dome that is used for observation instrument protection in empty day, in (fixed building) top to empty day observation instrument sight chamber, be provided with the dome of hemispherical (or super hemisphere), the top of this sight chamber is provided with the dome guide rail, the chassis of described dome has walking roller, this walking roller is arranged on the described dome guide rail, can be along this dome guide rail movement; Slotted in the middle of the described dome, this is furnished with the skylight above slit, it is characterized in that: the quantity of described walking roller (for example, has 6 walking rollers, when the dome bore strengthens for the even number greater than 4, the also corresponding increase of walking roller number), wherein half is power wheel, and second half is that driven pulley is (that is, unpowered, only do supporting role), power wheel and driven pulley are placed at interval; Be equipped with actuating unit on described each power wheel.
Above-mentioned actuating unit can be provided with in such a way: motor slows down through reductor by the axle of going into of belt (or chain) connection reductor, connects power wheel by belt (or chain) again, and it is rotated on circular guideway.
The present invention will be provided with from concentrating the type of drive of empty day observation instrument sight chamber dome, changes setting dispersion, multiple spot into.Reduced the space that driving mechanism occupies significantly.
In other words, structure of the present invention is: above the fixed building to empty day observation instrument sight chamber is the spheroid part of dome, (close the skylight) in the time of in off position, observation instrument (telescope) is fully topped in spheroid inside, effectively prevent the erosion (as Fig. 1) to observation instrument such as wind, rain, sand and dust.
Dome is the sphere structure of hemisphere or super hemisphere, and the slit that a width does not wait is opened in the centre, is furnished with the skylight above, and the spheroid of dome partly is installed on the chassis, and walking roller is installed in the below, chassis.Actuating unit (as Fig. 2) is set in inside, chassis, motor connects reductor by belt (or chain) and goes into axle, slows down through reductor, connects power wheel by belt (or chain) again, it is rotated on circular guideway, thereby finally drive the azimuth rotation of dome.
The present invention has adopted brand new dome orientation type of drive, and unidimensional relatively conventional servo-actuated dome has increased usage space in the dome, and Multipoint Drive makes the operation of dome more steady.
