Double-fan-shaped rotating laser automatic theodolite device

Abstract

The invention discloses a double-fan-shaped rotating laser automatic theodolite device. The automatic theodolite device comprises a double-fan-shaped rotating laser emitting head, a non-contact power supply device, a datum laser emitting device and a transmission shaft system; a point laser device and a cubic spectroscope of the double-fan-shaped rotating laser emitting head are fixed to a rotating base, collimation light emitted by the point laser device passes through a rotating shaft of the rotating base and is divided into two light beams by the cubic spectroscope at the rotating shaft of the rotating base, and the two light beams are irradiated to divergence arrises of two Powell prisms; the non-contact power supply device is used for supplying power to a driving circuit of the point laser device; the transmission shaft system comprises a transmission shaft, and the transmission shaft is connected with the double-fan-shaped rotating laser emitting head and a rotating encoder code disc of the datum laser emitting device. The horizontal angle and pitch angle of the target position can be automatically measured in the mode of externally arranging a photoelectric sensor without manual alignment, and a measured object can be traced and measured in real time on site.

Description

technical field [0001] The invention relates to the technical field of large-scale space measurement, in particular to a rotating laser automatic theodolite device. Background technique [0002] As the requirements for precise positioning and real-time measurement and control of large components in the manufacturing and assembly process of aviation, aerospace, ships and large power stations continue to increase, large-scale measurement technology is more and more widely used in industrial production. In recent years, the spatial coordinate measurement system composed of two or more theodolites with computers and corresponding hardware and software has been widely used in engineering surveying and metrology, using theodolite as the sensor. [0003] The traditional laser theodolite measurement system needs to manually align the target every time it is measured, which will not only reduce work efficiency, but also introduce errors artificially. [0004] In the large-scale meas...
