Umbrella multi-layer distributed load structure photoelectric tracking platform

Abstract

The invention provides a brand-new photoelectric theodolite tracking platform structure which can meet the photoelectric tracking requirements of wide-field system application. A photoelectric tracking platform with an umbrella-shaped multilayer distributed load structure comprises multiple layers of rotary tables, wherein each two adjacent layers of rotary tables are fixedly connected with each other through a transitional connection cover by screws; a direction tracking system and a pitching tracking system are arranged on each layer of rotary table, and each pitching tracking system is integrally fixedly mounted above the corresponding direction tracking system and comprises a servo hydraulic cylinder, a grating ruler assembly and multiple sets of connecting rod assemblies; each connecting rod assembly comprises a driving connecting rod, an intermediate connecting rod and a rotary connecting rod, which are sequentially hinged through rotary pins, and an optical system load is fixedly mounted on each rotary connecting rod; at one end of each connecting rod assembly, the rotary connecting rod is hinged to a fixed arm through the corresponding rotary pin, and at the other end of each connecting rod assembly, the driving connecting rod is fixedly mounted on a hydraulic piston, so that the reciprocating motion of the hydraulic piston in a vertical axial direction drives the pitching motion of the optical system load through the connecting rod assembly.

Description

technical field [0001] The invention relates to a photoelectric theodolite tracking platform. Background technique [0002] As we all know, the traditional optical tracking device, its tracking frame is a two-axis system including vertical axis and horizontal axis, which is usually defined as U-shaped and T-shaped structures according to the connection and load distribution of the stage. The traditional structure The design of the tracking frame is simple, and the analysis from the perspective of rigidity and natural resonant frequency is also conducive to improving the measurement accuracy of the system. However, based on this structure of the photoelectric tracking device, the optical load is placed in parallel along the vertical and horizontal axes, so even if multiple optical detectors are configured, the visual axes of all detectors converge to the same spatial position at infinity. The optical field of view of the system is determined by the size of the detector targe...
