Abstract
A raise measuring instrument is characterized in that an electroptic range finder (5) is movably connected with an electronic theodolite (4), the upper end of a fixed bracket (3) is fixed with the electronic theodolite (4), and the upper end of the electronic theodolite (4) is connected with the electroptic range finder (5), therefore, the utility model has convenient use, simple operation, and high accuracy and is safe and reliable, thereby greatly reducing the risk of the survey crew and the labor intensity. The raise measuring instrument is particularly suitable for the underground raise measurement of a mine.
Description
Technical field:
The utility model relates to a kind of surveying instrument, the surveying instrument of particularly a kind of mine courtyard.
Background technology:
The surveying instrument of down-hole, China mine courtyard is generally and uses box compass and tape measure to lay the compass lead at present, adopt the position angle of compass survey lead in the measuring process, tilt gauge is measured the inclination angle of inclination lead, tape measure is measured the oblique length of lead, the length of every station compass lead all is controlled at about 10-15 rice, because box compass, the measuring accuracy of tilt gauge and tape measure is lower, and box compass is subjected to the influence in magnetic fields such as People's Bank of China's ladder and geomantic omen pipe, the precision of measurement data is difficult to guarantee, often influence the perforation effect of engineering, and owing to survey crew in the measuring process will be climbed through whole courtyard, generally need to lay 5 to 7 station compass leads, personnel amount needs 3 people just can finish at least, Measuring Time was generally more than 2 hours, work high above the ground brings bigger risk to survey crew for a long time, thereby survey crew security extreme difference, and security incident very easily takes place.
Summary of the invention:
The purpose of this utility model is exactly that a kind of easy to use, simple to operate, safe and reliable, courtyard surveying instrument that accuracy rate is high will be provided.
The purpose of this utility model is achieved in that a kind of courtyard surveying instrument, form by courtyard (1), tunnel (2), it is characterized in that electro-optical distance instrument (5) and electronic theodolite (4) flexibly connect, fixed support (3) upper end is electronic theodolite (4) fixedly, and electronic theodolite (4) upper end connects electro-optical distance instrument (5).
The utility model compared with prior art has the following advantages:
Owing to adopted electro-optical distance instrument (5) and electronic theodolite (4) to flexibly connect, fixed support (3) upper end is electronic theodolite (4) fixedly, electronic theodolite (4) upper end connects the surveying instrument of electro-optical distance instrument (5), thereby it is easy to use, simple to operate, the accuracy rate height, safe and reliable, greatly reduce the risk and the labour intensity of survey crew.

Embodiment:
Electronic theodolite (4) model adopts the ET-2 type, electro-optical distance instrument (5) adopts the Memo-3 type, electro-optical distance instrument (5) flexibly connects with electronic theodolite (4), fixed support (3) upper end is electronic theodolite (4) fixedly, electronic theodolite (4) upper end connects electro-optical distance instrument (5), adjust electro-optical distance instrument (5) laser beam during use, make it parallel with direction of visual lines, after utilizing electro-optical distance instrument (5) laser spots to find measurement target, the horizontal angle of adjustment measurement target and backsight and instrument station are to the pitch angle of impact point, read electronic theodolite (4) coordinate figure, duplicate measurements three times is averaged, surveying work finishes, use this method can improve measuring accuracy, and reduced the security risk of survey crew, be particularly suitable for sky, down-hole, mine well measurements and use.
