Primary Mirror Dismounting Device for Large Telescopes

Abstract

The invention discloses a primary lens disassembly-assembly device for a large telescope. The large telescope comprises a lens cone and a main lens chamber. The primary lens disassembly-assembly device comprises a primary lens disassembly-assembly mechanism, rolling wheels and guide rails, wherein the primary lens disassembly-assembly mechanism comprises installation rod supports and installation rods; each installation rod support comprises bulges which are fixedly arranged on the sidewall of the lens cone and the sidewall of the main lens chamber respectively; each installation rod comprises a head cap part, a middle part and a thread part; each middle part is in clearance fit with the corresponding installation rod support, and is a smooth round rod which is not provided with a thread on the surface, the length of each middle part is less than the distance among the installation rod supports, and each thread part penetrates through the corresponding installation rod support and is in thread fit with the installation rod support; the rolling wheels are fixedly arranged on the lower part of the main lens chamber; and the guide rails are correspondingly arranged below the rolling wheels. The device disclosed by the invention is simple and convenient to operate, especially applicable to movable observation equipment with a narrow operation space, and low in requirements on the bottom space of the telescope; and the device disclosed by the invention is simple in structure, light in mass, and low in influence on the overall structural dimensions and weight of the telescope.

Description

technical field [0001] The invention belongs to the field of optical instruments, in particular to a disassembly and assembly device used in the disassembly and assembly process of the main mirror of a large telescope. Background technique [0002] As an important equipment for photoelectric detection, large optical telescopes are playing an increasingly important role in the military and astronomical fields of countries all over the world. However, as the caliber increases, other problems caused by the huge structural system become more and more prominent. The disassembly and assembly of the main mirror room is one of them. [0003] The environment is critical to the influence of optical precision instruments. Changes in ambient temperature, gas, and humidity may cause deformation of the primary mirror surface, and the primary mirror and primary mirror chamber parts are also prone to contamination, corrosion, and even mold growth. Environmental vibration and shock may ca...

AI Technical Summary

Problems solved by technology

[0004] Due to the large aperture of the primary mirror of a large telescope, the primary mirror chamber is not only large in size but also heavy in weight, so it is extremely difficult to disassemble and assemble the primary mirror chamber

At present, the lifting equipment is generally used to lift through the ring, and the method of direct disassembly and assembly is used. The operation has certain risks and requires a large space.
