The utility model provides the laser lower centring device for the electronic theodolite, which has simple structure, low manufacture cost, simple operation and convenient use.
Description
Technical field
The utility model relates to ray machine TV university ground surveying instrument, especially for centralising device under a kind of laser of electronic theodolite, it than adopt under the traditional optical centering transit product more directly perceived, use more rapid and convenient, be a developing direction of electronic theodolite, be applicable in the more wide foundation construction common survey.
Background technology
In control survey, measurement of angle is the observation work of basic maximum, and the precise electronic transit is the most frequently used instrument of present measurement of angle, and following centralizer is a composition of transit basic structure.Rotating part when vertical axle system of installing is horizontal direction observation in transit is the rotary support mechanism of transit alidade.According to the coaxiality requirement of transit, the axle center of alidade turning axle, horizontal dial are delineated the center should be consistent, is commonly referred to centre.When using transit to measure, the centre placing frame need be located on the survey station point of ground, carry out all surveying works as reference point.In traditional transit, use a kind of optical facilities to be commonly referred to optical centering device, provide an optics collimation axis by this mechanism, and transfer dress to guarantee that this optics central visual axis line overlaps with the rotary axis system of instrument, when using apparatus measures, when can from these optical facilities, see ground survey station o'clock in 360 degree orientation all on the collimation axis, confirm that promptly centre correctly is placed on the survey station point.Optical centering device needs human eye to observe repeatedly for a long time when using, very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, low cost of manufacture; Centralising device under a kind of laser that is used for electronic theodolite simple to operate, easy to use.
The purpose of this utility model is to realize like this, be used for centralising device under a kind of laser of electronic theodolite, it is characterized in that: on the transit alidade, be connected and fixed the laser instrument indicating device by cylindrical long tube, one 45 degree prism is installed apart from the outlet 40-50mm place of the laser hole drilling illuminator of laser instrument indicating device, a vertical incidence face of 45 degree prisms is vertical with the light path of laser hole drilling illuminator, and another vertical incidence face of 45 degree prisms projects ground survey station point with laser beam.
Described laser hole drilling illuminator is fixed in the cylindrical long tube, the central axis of cylindrical long tube overlaps with the laser hole drilling illuminator output optical axis, cylindrical long tube is positioned at the stomidium in the transit alidade outside, laser hole drilling illuminator connects rotary switch by lead and controls its switch, and laser indication light beam is sighted on the survey station point of ground by 45 degree prisms.
Advantage of the present utility model: because the utility model adopts the linear laser beam indication ground survey station point after collimating, laser beam directivity behind the collimation is good, the angle of divergence is very little, this laser beam overlaps with the instrument axis of rotation of electronic theodolite after transferring dress, when laser beam was sighted ground survey station point, the centre of gyration of instrument was that centre correctly is erected on the survey station point of ground.Simpler than traditional optical direction structure, manufacturing cost reduces; Easy to operate.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail:
