Magnetically suspended gyroscope total station

Abstract

The invention relates to a magnetically suspended gyroscope total station, comprising a directional sighting system, a computer processing system, an angle measuring system, a gyroscopic slewing system, a light path auto-collimation system and a magnetic suspension system, wherein the gyroscopic slewing system, the light path auto-collimation system and the magnetic suspension system are arranged in a metal shell; the center position of the bottom part of the metal shell is provided with a lower centering identification hole; and the top of the metal shell is provided with a northward designator. When a linkage in the magnetic suspension system is in a suspending state, a spring is in a compressing state, and the upper surface of a photoelectric sensor is parallel and level with the receiving surface of the light path auto-collimation system; and when a rod meter shell falls back from the suspending state, a tabletting is contacted with a contact, and a dropping cone falls into a faller trough and is in a locked state. In the invention, the magnetic suspension technology is utilized to substitute the traditional hanging belt bearing technology, thus the problems of the traditional hanging belt type gyroscope hang spring such as easy damage, long orientation time, cockamamie operation and the like are solved. The magnetically suspended gyroscope total station has the advantages of high automaticity, rapid orientation, stable overall performance and the like.

Description

technical field [0001] The invention relates to a magnetic levitation gyroscope total station which can be widely used in many large-scale underground penetration projects such as urban subway projects, mountain tunnels, river subsea tunnels and the like. Background technique [0002] In the construction of many underground projects such as urban subway projects, mining and river tunnels, it is a very important measurement work to ensure safe and accurate penetration of tunnels. However, due to various limitations of the special environment of underground engineering, some high-precision measurement techniques on the ground often cannot be implemented in underground engineering. With the continuous extension of the underground mining face, the directional error of the tunnel will continue to accumulate, which will eventually lead to the failure of the breakthrough, and even cause major engineering accidents. Therefore, in the underground engineering survey, the method of gy...
