KR-102961480-B1 - Surveying tripod system that is easy to install at each reference point

Abstract

The present invention relates to a surveying tripod system that is easy to install at reference points. More specifically, it is a system that facilitates the installation of a tripod at reference points by enabling evasive maneuvers so that the surveying instrument can move while the tripod remains in place, regardless of the obstacle, when an obstacle occurs when a surveying tripod is installed at a reference point. Furthermore, it promotes the stabilization of geodetic surveying operations by implementing a shock-absorbing function of the support leg that constitutes the tripod with a double cushioning structure against external impacts, and improves the structure of the flat plate used for geodetic surveying to implement tilt control or rotation control functions of the flat plate itself, thereby increasing convenience and ease of use during geodetic surveying using the flat plate, ensuring the efficiency of surveying operations, and shortening the working time.

Description

Surveying tripod system that is easy to install at each reference point The present invention relates to a surveying tripod system that is easy to install at reference points in the field of geodetic surveying technology. More specifically, it is a system that facilitates the installation of a tripod at reference points by enabling evasive maneuvering so that the surveying instrument can move while the tripod remains in place, regardless of the obstacle, when an obstacle occurs when a surveying tripod is installed at a reference point. Furthermore, it promotes the stabilization of geodetic surveying operations by implementing a shock-absorbing function of the support leg that constitutes the tripod with a double cushioning structure against external impacts, and improves the structure of the flat plate used in geodetic surveying to implement tilt control or rotation control functions of the flat plate itself, thereby increasing convenience and ease of use during geodetic surveying using the flat plate, ensuring the efficiency of surveying operations, and shortening the working time. Cadastral surveying is a survey conducted to register land on a parcel-by-parcel basis to clarify the limits of property rights over the land (location, size, shape, boundaries, etc.), and involves only two-dimensional (x,y) positions. For such cadastral surveying, a foundation survey is conducted. A foundation survey is a survey performed to install base points necessary for cadastral surveying or to carry out detailed surveying. Cadastral surveying requires a leveling rod and a tripod, and each needs to be adjusted in height. To make the explanation and understanding simple and easy, the following description will be based on the tripod. Meanwhile, since cadastral surveying is conducted to clarify the limits of property rights, residential areas are the primary target. However, in the case of houses, it is difficult to accurately measure the position of the lower plane of the aforementioned protrusions due to roof protrusions such as eaves. In particular, the difficulty was even greater when performing surveying using GPS surveying equipment. Accordingly, conventionally, the pole on which the surveying instrument is installed is bent into a 'U' shape, and the surveying instrument is installed at the top of the pole to survey the location to be measured. However, conventionally, it was difficult to accurately adjust the lateral length of the pole forming a 'U' shape, making it difficult to adequately respond to various protrusions on the roof. Therefore, there were difficulties in ensuring the precision of the survey. In addition, conventionally, the structural complexity of fixing the poles required a significant amount of time and labor to install them. As a prior art that partially improves upon these problems, Korean Patent Registration No. 10-1479604 (January 8, 2015) discloses 'surveying equipment for precise cadastral surveying'. However, conventional surveying equipment for precise cadastral surveying has a problem in that as the distance between the middle curved pole and the upper curved pole increases, the middle curved pole may sag downward due to the load of the upper curved pole and the cadastral surveying equipment, potentially leading to damage such as the middle curved pole breaking. To improve this, it became the subject of Korean Patent Registration No. 10-1870681 (June 19, 2018), titled 'Height adjustment system for a leveling rod and tripod for geodetic surveying'. However, since the survey reference point is fixed, it is difficult to maneuver to avoid an obstacle if one arises near the reference point. To maneuver to avoid it, the reference point must be changed, but this requires going through the cumbersome procedure of acquiring a new reference point, which leads to a considerably difficult problem. Accordingly, there is a need for a tripod system that ensures ease of installing effective reference points.
