The power needed is big, and when protective cover opens execution task, protective cover space shared outside theodolite body is larger, is unfavorable for
Outfield condition of work.Both the above protects cover structure because quality is larger simultaneously, and theodolite master will be influenceed after opening or closing
The position of centre of gravity of optical system, problem is carried out to weight belt.
The content of the invention
The invention solves the problems that technical problem of the prior art is automatically controlled there is provided one kind, easy to operate, light weight, body
The small, reliability of product is high, heavy caliber electro-optic theodolite lens barrel protective cover.
In order to solve the above-mentioned technical problem, technical scheme is specific as follows：
A kind of heavy caliber electro-optic theodolite lens barrel protective cover, including：It is drive shaft, driving wheel, cog belt, driven pulley, driven
Wheel seat, shading body, driving crossbeam and overload protection component；
Drive shaft and driving wheel are connected by key；Driving wheel, driven pulley, cog belt composition transmission component；Driven pulley is fixed
On driven wheel seat；Driving crossbeam two ends are fixed on drive block；Motor and cone pinion are coaxially connected and be fixed on motor cabinet
On；Gear wheel and drive shaft are fixedly and coaxially connected；Shading body top edge is fixed on driving crossbeam, and shading body briquetting will hide
Trimmed book body lower edge is fixed in theodolite protective cover main body；Motor, which is rotated, can make shading body perpendicular to drive axis side
Open up, close；It is not rotated further by when shading body reaches defined position rear drive shaft；
The overload protection component includes：The lock nut and gear bush of threaded connection；Lock nut turns on axle sleeve
The thrust of dynamic adjustment stage clip, stage clip is pressed on gear wheel, and gear wheel and gear bush are connected by steel ball, gear bush and institute
Drive shaft is stated to be fixedly connected；
In the above-mentioned technical solutions, when shading body reaches the spacing failure of defined position electricity or midway shading body card
When dead, gear wheel compression press spring is simultaneously moved to stage clip shrinkage direction, and little gear disconnects drive connection with gear wheel.
In the above-mentioned technical solutions, the shading body is organ cover, its stretchable, folding, light tight in face of the sun, outside
Superficial white, inner surface black.
The present invention has following beneficial effect：
The heavy caliber electro-optic theodolite lens barrel protective cover of the present invention, as protection body, can be opened, folded using organ cover,
Overall weight is light, small volume；Running part worm-drive, it is ensured that organ cover does not sink voluntarily, overload protection component, which is realized, to be protected
The effect of motor is protected, easy to operate, reliability is high, is automatically controlled while can realize.
