Abstract

The invention discloses a device for hoisting a FAST (five-hundred-meter aperture spherical radio telescope) reflection surface unit. The device comprises a rail locomotive and an operation locomotive which operate on a ring beam, wherein a center ring beam is arranged at the center position of a radio telescope; a bearing rope is connected between the rail locomotive and the center ring beam; a bearing tackle capable of sliding along the bearing rope is arranged on the bearing rope; the operation locomotive transfers the reflection surface unit to the rail locomotive and suspends the reflection surface unit on the bearing tackle; a traction rope connected with the bearing tackle is arranged on the rail locomotive; under the traction of the traction rope, the reflection surface unit is hoisted and transported to a position above a corresponding mounting position of a main cable net; a winding mechanism for unloading the reflection surface unit to the corresponding mounting position of the main cable net is arranged on the bearing tackle; the connection end of the bearing rope to the center ring beam can slide along the center ring beam; the work is repeated, so that the hoisting transportation on all the mounting positions on the main cable net is realized.

Description

technical field [0001] The invention relates to a hoisting device for a FAST reflector unit, through which the reflector unit of a radio telescope can be hoisted to the installation position of a main cable net. [0002] Background technique [0003] The National Astronomical Observatory of the Chinese Academy of Sciences proposed to build a 500-meter-caliber spherical radio telescope, which is the world's largest single-caliber radio telescope. FAST (Five-hundred-meter Aperture Spherical radio Telescope, referred to as FAST) has broken through the 100-meter engineering limit of ground-based telescopes and created a new model for building giant radio telescopes. The overall technical indicators of FAST: the aperture is 500m, the radius of curvature of the reflective surface is 300m; the aperture of the lighting area is 300m, and the focal ratio f / D =0.467. [0004] The FAST active reflector is composed of ring beams, reflector units, main cable nets, actuator devices, grou...
