Construction engineering multi-angle mapping instrument based on Rotating shaft

Abstract

The invention discloses a construction engineering multi-angle mapping instrument based on a Rotating shaft. The construction engineering multi-angle mapping instrument comprises a base, a first rotating shaft is rotationally connected with the center of the upper surface of the base, a horizontal angle disc is embedded in the outer side of the first rotating shaft on the upper surface of the base, a first pointer is fixed on the first rotating shaft through a first sleeve, a U-shaped seat is welded at the top of the first rotating shaft, and a laser level gauge is rotationally connected withthe interior of the U-shaped seat through a second rotating shaft. The multi-angle mapping instrument disclosed by the invention has the benefits that as the U-shaped seat is rotationally connected with the fixed seat through the first rotating shaft, through the rotation of the first rotating shaft, a horizontal angle of the laser level gauge fixed on the U-shaped seat can be changed; when the first rotating shaft rotates, the first pointer fixed by the first sleeve on the first rotating shaft can rotate on the horizontal angle disc, so that a user intuitively observes the horizontal adjustment angle of the laser level gauge, the adjustment convenience of the laser level gauge is improved, and the mapping accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering surveying and mapping, in particular to a rotating shaft-based multi-angle surveying and mapping instrument for construction engineering. Background technique [0002] In industrial and agricultural construction and various civil engineering constructions, a large amount of surveying and mapping work is required from the survey and design stage to the construction completion stage. The commonly used measuring instrument is a laser level, which uses a laser beam instead of manual reading. , has the characteristics of high precision, long line of sight and automatic reading and recording. [0003] Existing surveying and mapping instruments for construction projects have a simple structure. Generally, a single one can only adjust the horizontal angle, but cannot adjust the vertical angle. Secondly, the adjusted angle cannot be automatically observed, which makes its adjustment more t...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing surveying and mapping instrument for construction engineering has a simple structure, generally a single one can only adjust the horizontal angle, but cannot adjust the vertical angle. Secondly, the adjusted angle cannot be automatically observed, which leads to its adjustment It is more troublesome and affects the accuracy of its surveying and mapping. It provides a multi-angle surveying instrument for construction projects based on Rotating shaft.
