Description

A kind of centering apparatus for leveling for measuring training
Technical field
The utility model relates to fields of measurement, particularly relates to a kind of centering apparatus for leveling for measuring training.
Background technology
In power transmission and distribution line construction is measured, use more surveying instrument to be optical theodolite (total powerstation etc.), belong to precision optical instrument, price costly.And line construction measurement is engaged in that the sector newly enters employee, the junior college of close specialty, the practising method of technology universities and colleges, electric system power transmission and distribution specialty employee take appointment with certificate examination, grade of skill promotes the specialty of taking an examination and must relate to, be unable to do without to measure in training, examination and train instrument.And measure centering in training, leveling exercise is the basis of all measurement practical operation projects.There is no the centering of surveying instrument, flatten the line construction measurement of being just far from being real.The object of surveying instrument leveling makes instrument vertical pivot be in plumb position by adjusting measuring apparatus device level tube bubble exactly.The object of surveying instrument centering settles instrument Shi Qi center and survey station point mark to be positioned on same pedal line exactly.The tripod plumb bob centering or optical plummet centering of laying surveying instrument can be utilized in actual measurement work.All surveying instrument centerings, leveling are all to make the data of collection more accurate.If not leveling, the vertical angle measured and horizontal angle just inaccurate, if misaligned, the Distance geometry angle of measurement is not just started at from pendulum website.The guarantee of the precision of centering, leveling more high measurement data precision is also higher.
In daily measurement training, trainee is in order to practise the precision measuring centering, leveling, again and again dismounting optical theodolite (total powerstation) and tripod.Often in Training and Learning, improper use, accidentally easily cause precision optical instrument to damage, the expense of maintenance is not low especially.Even skilled survey work, also easily neglect when landform complicated in the wild or when using optical theodolite (total powerstation) to carry out centering, leveling for a long time under severe meteorological condition or cause instrument damage because of carelessness, add instrument maintenance expense, decrease instrument normal cycle service time.
Utility model content
The purpose of this utility model is for above weak point, providing a kind of centering apparatus for leveling for measuring training, greatly shortening Measuring Time, improve measurement efficiency.
The scheme that the utility model technical solution problem adopts is a kind of centering apparatus for leveling for measuring training, comprise the face glass of a level, the shape of described face glass is consistent with the pedestal of tripod, the middle part of described face glass is fixed with a circle air level, and all lateral edges of face glass are respectively arranged with three horizontal levelling bubbles, described three horizontal levelling bubbles are equal relative to the distance of described round air level, a laser LED lamp is also provided with below described face glass, described laser LED lamp is vertically installed in below in the middle part of face glass and passes tripod mount through hole.
Further, be embedded with a nut bottom described face glass, described laser LED lamp one end is provided with external thread along its length, and described laser LED lamp is connected with described nut screw connection through described external thread.
Further, the base plate of described face glass is provided with one for the disk of embedded described nut, and described disk is placed in the through hole of tripod pedestal.
Further, described face glass subscript is marked with the scale for preventing circle air level, and described scale from inside to outside indicates.
Further, the thickness of described face glass is 10mm, and is transparent perspex panels.
Compared with prior art, the utility model has following beneficial effect: the centering leveling being completed tripod by the cooperation of described apparatus for leveling and laser LED lamp, is ensured the levelness of surveying instrument, thus guarantee the accuracy of measurement result.The utility model is for measuring training, and not only structure is simple, easy to operate, and greatly shortens Measuring Time, improves measurement efficiency.
