Surveying and mapping instrument for building engineering surveying and mapping

Abstract

The invention discloses a surveying and mapping instrument for building engineering surveying and mapping, which comprises a base, wherein the top of the base is fixedly connected with a vertical plate, the middle of the vertical plate is provided with a mounting groove, the middle of the mounting groove is rotatably connected with a lead screw, the surface of the lead screw is in threaded connection with a lifting sleeve, and the middle of the lifting sleeve is fixedly connected with a connecting block; a lifting box is fixedly connected to the side, away from the lifting sleeve, of the connecting block, a fixing table is fixedly connected to one side of the lifting box, a supporting table is rotationally connected to the top of the fixing table, a surveying instrument body is mounted on the top of the supporting table, and a partition plate is fixedly connected to the middle of the inner wall of the lifting box. According to the surveying and mapping instrument for constructional engineering surveying and mapping, the base, the vertical plate, the lifting box, the fixing table and the surveying and mapping instrument body are arranged, so that height adjustment is achieved, use is convenient, and the working efficiency is improved; by additionally arranging a dust collection fan, a collection box and a dust collection cover, dust is prevented from floating and blocking surveying and mapping sight, and meanwhile, dust attached to the surveying and mapping instrument body is reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a surveying and mapping instrument for construction engineering surveying and mapping. Background technique [0002] Surveying and mapping instruments are often used in construction projects. Surveying and mapping instruments, simply speaking, are instruments and devices designed and manufactured for surveying and mapping operations such as data acquisition, processing, and output, and various orientation, ranging, and Angle, altimetry, mapping and photogrammetry instruments. [0003] The existing surveying and mapping instruments for construction engineering are usually supported by brackets at the bottom during actual use. When the height of the surveying and mapping measurement needs to be changed, it is inconvenient to adjust the height of the surveying and mapping instrument on the top, which reduces the efficiency of surveying and mapping work. There is usually a l...

Problems solved by technology

[0004] The object of the present invention is to provide a surveying and mapping instrument for construction engineering, to solve the above-mentioned background technology. The existing surveying and mapping instrument for construction engineering is usually supported by a bracket at the bottom during actual use. When it is necessary to change the surveying and mapping measurement It is inconvenient to adjust the height of the surveying instrument on the top, which reduces the efficiency of surveying and mapping work. At the same time, there is usually a lot of dust on the construction site. When there is a lot of dust, it will block the observation line of sight and affect the surveying work.
