Abstract

An electronic theodolite is characterized in that a lower laser plummet is fixed to the rear side of a body, a transverse shaft is arranged in the middle of the body, a perpendicular encoding disk is fixed to an end face of the transverse shaft in the interior of the left side of the body, two sides of the perpendicular encoding disk are provided with a group of perpendicular reading heads respectively, the transverse shaft is in a single shaft structure, and a compensator used for compensating angle errors of a perpendicular angle is arranged in the body. By the aid of an absolute encoding disk angle measuring system and integration of optical-electro-mechanical and computing technology, a horizontal angle and a vertical angle can be displayed simultaneously, the functions of the slope conversion and the slope compensation of the vertical angle can be realized, and the angle measuring accuracy can reach 2''. The electronic theodolite can be widely used for control and survey for three-order triangulation and four-order triangulation, constructions, installation of large equipment, cadastral survey, topographic survey and survey for various engineering such as railways, highways, bridges, hydraulic engineering, mines and the like. Accurate measurement of angles is realized, and quality of engineering construction is effectively ensured.

Description

A kind of electronic theodolite

Technical field

A kind of electronic theodolite 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, 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, and 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 adjusting a relative complex, also having because transverse axis adopts the structure of three grades of connections, in the rotation process will there be than large deviation vertical reading.

The utility model content

The purpose of this utility model is to overcome the existing defective of transit, adopts the absolute encoder angle measuring system, design a kind of zero passage that do not need and just can read angle-data, and light harvesting, mechanical, electrical and computing technique realize accurately a kind of electronic theodolite of measurement in one.Its technology is achieved in that and comprises pedestal, the horizontal stop fine motion, display, vertical only fine motion, right plate, body, handle, telescope, vertical read head, vertical code-disc, left plate, battery, plate level, mainboard, vertical pivot, horizontal read head, horizontal code-disc, following disc main body, compensator is in interior structure, it is characterized in that: the body rear side is fixed with down the laser counter point device, the centre of body is provided with transverse axis, 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 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, topographical surveying and the various engineering of main equipment measure.Realize the accurate measurement of angle, effectively guaranteed the quality of engineering construction.
