The total station comprises a base, a vertical shaft, a bracket, a camera and a ranging block, and also comprises a laser emission tube, a reflector, a beam splitter prism, and a condensing lens, wherein the laser emission tube is connected with a ranging plate inside the camera; a right-angle edge of the reflector is parallel to an emission beam of the laser emission tube and passes through a midpoint of an inclined beam; a straight line formed by the midpoint of the inclined edge of the beam splitter prism and the midpoint of the inclined edge of the reflector is vertical to the beam emitted by the laser emission tube; and the central point of the condensing lens and the midpoint of the inclined edge of the beam splitter prism are on the same horizontal line. By adopting the total station, the problem that the total station cannot work in a poor environment, and the problems of complicated process, high cost and low work efficiency are effectively solved.

Description

Total powerstation with laser indication function

Technical field

The utility model relates to surveying instrument, particularly a kind of total powerstation with laser indication function.

Background technology

Total powerstation mainly by power supply, angle measuring system, range measurement system, data processor, communication interface, and display screen, keyboard etc. form.At present because total powerstation can take measurement of an angle, distance and coordinate are widely used.Though these basic functions of total powerstation can satisfy the needs of daily surveying work, still, when long or light condition is not very desirable working environment in distance, use total powerstation to search target more difficult, and when using the total powerstation setting-out, the setting-out personnel are difficult for determining the position of setting-out, time and effort consuming.In existing society, laser technology is comparative maturity, and is used widely.Laser has that monochromaticity is good, high directivity, brightness high.

Therefore, field of measuring technique is badly in need of a kind ofly can overcoming abominable working environment and finding target accurately, facilitates staff's setting-out, and technique is simple, the total powerstation with laser indication function that cost is low, work efficiency is higher.

The utility model content

The utility model provides a kind of total powerstation with laser indication function, comprises pedestal, vertical pivot, support, camera, range finding chunk, also comprises:

LASER Discharge Tube is connected with locater plate in camera;

Catoptron, this catoptron one right-angle side is parallel with the emission light beam of this LASER Discharge Tube and by hypotenuse light beam mid point;

Amici prism, the straight line that this Amici prism hypotenuse mid point and catoptron hypotenuse mid point form is perpendicular to the light beam of this LASER Discharge Tube emission;

Collector lens, central point and this Amici prism hypotenuse mid point are in the same horizontal line.

The beneficial effects of the utility model are:

1. the utlity model has the total powerstation of laser indication function, can be convenient to find target, facilitate staff's setting-out, improve the work efficiency of measuring.

2. the utlity model has the total powerstation of laser indication function, can adapt to various rugged environment work, have applicability widely.

3. the utlity model has the total powerstation of laser indication function, is to improve on the basis of original total powerstation, and technique is simple, the saving cost.

Description of drawings

Describe the utility model patented technology in detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the structural representation that the utlity model has the total powerstation of laser indication function.

Embodiment

For measure, creation characteristic that the utility model technology is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Fig. 1 is the structural representation that the utlity model has the total powerstation of laser indication function.

The utility model provides a kind of total powerstation with laser indication function, comprises pedestal, vertical pivot, support, camera, range finding chunk, also comprises:

LASER Discharge Tube 1 is connected with locater plate in camera;

Catoptron 2, catoptron 2 one right-angle sides are parallel with the emission light beam of LASER Discharge Tube 1 and pass through hypotenuse light beam mid point, receive the light beam of this LASER Discharge Tube 1;

Amici prism 3, the straight line that these Amici prism 3 hypotenuse mid points and catoptron 2 hypotenuse mid points form is perpendicular to the light beam of LASER Discharge Tube 1 emission, and Amici prism 3 receives the light beam of this catoptron 2;

Collector lens 4, central point and this Amici prism 3 hypotenuse mid points in the same horizontal line, collector lens 4 receives the light beam of Amici prisms 3.

As above structure makes the observation station of laser designation point and total powerstation on same axis.

Fig. 2 is the laser guide figure that the utlity model has the total powerstation of laser indication function.

Using the utility model to carry out laser guide measures, in the situation that setting-out personnel setting-out has great difficulty, at first open total powerstation range finding switch, locater plate transmits to LASER Discharge Tube 1 one, one of the chunk of finding range simultaneously moves towards signal, makes it no longer block the emission of light of LASER Discharge Tube 1; The light of LASER Discharge Tube 1 emission reflexes on Amici prism 3 through catoptron 2, again through Amici prism 3 light splitting, by collector lens 4 centers ejaculations, shine on target, at this moment, the point that the range finding personnel see in eyepiece is consistent with the point that laser shines, then adopts the range finding chunk of total powerstation accurately to measure.

The utility model efficiently solves rugged surroundings and can not work, complex process, the problem that cost is high, work efficiency is lower.

Above demonstration and described the advantage of ultimate principle of the present utility model, principal character and the utility model patented technology.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the principle that the utility model patented technology just is described of describing in above-described embodiment and instructions; the utility model patented technology also has various changes and modifications under the prerequisite that does not break away from the utility model know-why and scope, and these changes and improvements all fall in the scope of claimed the utility model patented technology.The claimed scope of the utility model patented technology is defined by appending claims and equivalent thereof.
