Description

A kind of electronic laser transit

Technical field

A kind of electronic laser transit of the utility model, what relate to is transit design and manufacturing technology field, particularly electronic theodolite technical field.Be applied to measurements such as engineering, building, land deeds, landform.

Background technology

At present, domestic engineering, building, land deeds, spirit-leveling instrument is generally adopted in measurements such as landform, transit, total powerstation or the like, wherein, spirit-leveling instrument can only be used for level measurement, work such as measurement such as elevation transmission measurement, certain limitation is arranged, total powerstation is as full standing posture electronic tachometer, be used for the engineering location, measurement function is more relatively, but the instrument price is higher, failure rate is higher relatively under the duty, and transit is used for a some position to be measured and an engineering location survey, and it is divided into two kinds of optical theodolite and electronic theodolites, optical theodolite price high measurement speed is slow and influenced more greatly and gradually by construction site light to be eliminated, existing electronic theodolite adopts the relative coding device mostly, must zero passage can use after the start, employing be optical plummet to point mode, to an adjustment relative complex, also have because transverse axis adopts the structure of three grades of connections, in the rotation process will there be than large deviation vertical reading, can't effectively measure at the working environment of dark.

The utility model content

The purpose of this utility model is to overcome the existing defective of transit, adopt the absolute encoder angle measuring system, design a kind of zero passage that do not need and just can read angle-data, light harvesting, mechanical, electrical and computing technique realize a kind of electronic laser transit of accurately measuring in one.Its technology is achieved in that and comprises pedestal, the horizontal stop fine motion, following laser counter point device, display, compensator, vertical only fine motion, body, right plate, handle, telescope, vertical read head, vertical code-disc, transverse axis, left plate, battery, plate level, mainboard, horizontal read head, horizontal code-disc, vertical pivot, following disc main body is in interior structure, it is characterized in that: the rear side of body is fixed with down the laser counter point device, the centre of body is provided with a transverse axis, intrinsic transverse axis right side is fixed with brush, the active telescope that is fixed with on the transverse axis, be fixed with laser instrument above the telescope, the end face of the transverse axis that the body left side is inner is fixed with vertical code-disc, the both sides of vertical code-disc respectively are provided with one group of vertical read head, described upward laser instrument and telescope are coaxial with burnt, described transverse axis adopts the structure of single shaft, is provided with the compensator that the angular error to vertical angle compensates in the body.The beneficial effects of the utility model are: adopt the absolute encoder angle measuring system, light harvesting, mechanical, electrical and computing technique are in one, reveal competence and vertically angle simultaneously, and can realize the slope conversion of vertical angle and the slope compensation function of vertical angle, angle measurement accuracy can reach 2 ".Can be widely used in three, the control survey of fourth class triangle, be used for the engineering survey of aspects such as railway, highway, bridge, water conservancy, mine, also can be used for building, installation and land deeds, the topographical surveying of main equipment and need engineering survey at the working environment of dark.Realize the accurate measurement of angle, effectively guaranteed the quality of engineering construction.
