Abstract

The invention relates to a separating type azimuth angle vertical transmission device aiming to solve the problems of large volume and poor adaptability of the prior azimuth angle vertical transmission device. The separation type azimuth angle vertical transmission device comprises a theodolite, a light source assembly, a photoelectric positioning device and an angle transmission device, wherein the theodolite comprises a telescope and a base; the light source assembly comprises a light source, a condensing mirror and a cylindrical mirror; and the theodolite, the light source assembly, the photoelectric positioning device and the angle transmission device are connected in a separating way. The separating type azimuth angle vertical transmission device has simple structure and low cost, adopts a high-precision output positioning method, can reduce the drifting influence of the photoelectric positioning device and enhance the alignment sensitivity, adopts one light source, simplifies the structure by a method that cylindrical mirror is diffused into a bright line and enhances the stability of the device.

Description

technical field [0001] The invention relates to the field of measuring and testing technology and instruments, in particular to a separate vertical transfer device. Background technique [0002] The transfer of azimuth refers to transfer the azimuth to the unknown line after measurement based on the line with known azimuth, and obtain the azimuth of the unknown line. The transmission of azimuth can be divided into two types: horizontal transmission and vertical transmission. Horizontal transmission is a commonly used and mature technology, which is transmitted through the alignment of theodolite, and its method belongs to the "traverse survey method" in geodesy. Vertical transfer is to transfer the azimuth angle from high to low or from low to high on the same plumb line. For example: through the vertical hatch of the ship, the known azimuth angle on the deck is transmitted to the cabin; the known azimuth angle of the wellhead of the industrial well is transmitted to the b...
