Supporting frame for surveying and mapping instruments

Abstract

The invention discloses a support rack for a plotting instrument. The support rack comprises a first centering rod, a second centering rod, a support rod as well as two spirit levels, wherein the first centering rod, the second centering rod and the support rod all comprise an outer tube and a telescopic inner tube which is inserted into the outer tube; the outer tube and the inner tube are fixed through handheld type locking pieces; the first centering rod and the second centering rod are vertically arranged in parallel in equal height; the first centering rod and the second centering rod are connected through a fixing connecting beam; the fixing connecting beam is horizontally arranged; the support rod is connected with the fixing connecting beam through a connecting component; a plotting instrument connecting base is arranged on the fixing connecting beam; the spirit levels are symmetrically distributed on the fixing connecting beam taking the plotting instrument connecting base as a longitudinal shaft. The support rack for the plotting instrument, which is disclosed by the invention, has the advantages of simple structure, convenience in operation and high stability, not only is accurate plotting operation achieved, but also solidity and reliability of the plotting support rack can be ensured, the working efficiency is high, and the plotting result is precise and accurate.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a support frame for a surveying and mapping instrument. Background technique [0002] The centering rod for surveying and mapping is an indispensable centering device in surveying and mapping, and has a wide range of uses in surveying and mapping. It is a retractable metal rod that can directly point to the ground marking point in the vertical direction. [0003] There are many specifications of existing centering rods, generally with different height specifications such as 2.15 meters, 2 meters, 3 meters, 5 meters, etc. Although the existing centering rods have been made into telescopic metal rod structures, their general performance has been improved from the height . [0004] However, the surveying and mapping instruments are all installed on the top of the centering rod, and only one surveying and mapping instrument can be assembled on the top of a ce...
