Abstract

The invention discloses a portable tower ruler for large-scale topographic surveying and mapping, which comprises: a support plate; three support leg assemblies, which are respectively installed on the side walls of the contracted support plate along the circumferential direction through pin shafts; the first tower section, The second tower section is adapted to be inserted into the inner cavity of the first tower section; the third tower section is adapted to be inserted into the second tower section. The inner cavity of the tower section; the fourth tower section is adapted to be inserted into the inner cavity of the third tower section; the fifth tower section is adapted to be inserted into the inner cavity of the fourth tower section. The portable tower ruler for large-scale topographic surveying and mapping can realize the straightening of the tower ruler in any environment and landform, without the need for manual support, avoiding the fatigue of the operator caused by long-term support and walking, and ensuring the stability of the leveling ruler Stable and accurate measurement results, and can be stretched and contracted quickly, easy to operate, saving time and effort.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a portable tower ruler for large-scale topographic surveying and mapping. Background technique [0002] The tower ruler is a kind of leveling ruler. It is made of aluminum alloy and other light and high-strength materials. It adopts a tower shrinkage form, which is easy to draw out during use. It is generally used in conjunction with a level or theodolite. In the process of large-scale topographic surveying and mapping, it is necessary to measure the elevation of the terrain at multiple locations, so as to provide reliable and reliable information for engineering construction. Most of the existing tower rulers need manual support, and the measurement accuracy is not high due to the influence of human interference factors; [0003] In the process of large-scale topographic surveying and mapping, the tower ruler needs to be in a vertical state for a long ti...
