Abstract

The invention belongs to the related field of GNSS antenna mounting equipment, and discloses a GNSS antenna mounting device suitable for railroad bridge deformation monitoring, which comprises a measurement connecting part, an embedded connecting piece and a mounting bracket, and is characterized in that the measurement connecting part is a transition element used for connecting a GNSS signal receiver and the embedded connecting piece and has a leveling function convenient to control; the device further comprises a connecting part body, a leveling lifting rod, a leveling nut, a horizontal topplate and other assemblies; the embedded connecting piece is in the form of a connecting rod and is used for connecting and fixing the measurement connecting part to the mounting bracket in a clampinggroove manner; and the mounting bracket is used for providing a stable engineering measurement bracket and is directly mounted and fixed on a prefabricated curtain board of a railroad bridge. According to the invention, satellite signals can be ensured not to be shielded, and the method is suitable for various complex installation environments, and has the advantages of good controllability, fastpositioning speed, high measurement precision, convenient later operation and maintenance and the like.

Description

Technical field[0001]The invention belongs to the related field of GNSS antenna installation equipment, and more specifically, relates to a GNSS antenna installation device suitable for railway bridge deformation monitoring.Background technique[0002]GNSS (Global Navigation Satellite System, Global Navigation Satellite System) technology has been widely used in municipal engineering, housing construction, highways and other engineering surveying fields. Its basic principle is to measure the distance between a satellite with a known position and a user receiver. Distance, integrate the data of multiple satellites to calculate the specific location of the receiver. Because of its high measurement accuracy, the ability to provide three-dimensional coordinates and all-weather measurement, it has greatly promoted the new development of measurement and navigation and positioning.[0003]However, due to the closed nature of railway operations and the reception of GNSS antenna signals cannot b...
