Auxiliary surveying and mapping device based on urban three-dimensional terrain

Abstract

An auxiliary surveying and mapping device based on urban three-dimensional terrains belongs to the technical field of surveying and mapping instruments and comprises a first limiting pipe, a second limiting pipe, a third limiting pipe and a fourth limiting pipe, limiting blocks are fixedly connected into the second limiting pipe, the third limiting pipe and the fourth limiting pipe respectively, through holes are formed in the limiting blocks, and through holes are formed in the limiting blocks. The limiting block is arranged in a hollow mode through the through hole, a first telescopic rod is installed in the through hole, the outer side wall of the top of the first telescopic rod is fixedly connected with the inner side wall of the limiting block, a second telescopic rod is installed in the first telescopic rod, and the first telescopic rod and the second telescopic rod are used for controlling movement of the drill rod. In the process that the driving motor controls the drill rod to rotate, the drill rod can conveniently extend into soil, and the gravity center of the auxiliary device in the using process is adjusted by adjusting the second limiting pipe, the third limiting pipe and the fourth limiting pipe and the positions, corresponding to the drill rod, in the second limiting pipe, the third limiting pipe and the fourth limiting pipe.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to an auxiliary surveying and mapping device based on urban three-dimensional topography. Background technique [0002] Surveying and mapping is surveying and drawing. Based on computer technology, photoelectric technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as the technical core, the existing feature points and boundaries on the ground are The graphics and position information reflecting the current situation of the ground are obtained by means of measurement, which can be used for planning, design and administrative management of engineering construction. [0003] In the prior art, the patent whose application number is CN202011425095.3 discloses an auxiliary surveying and mapping device for engineering exploration wi...
