Abstract

The invention relates to the technical field of FAST radio astronomical telescopes, particularly to an FAST reflecting surface unit self-adaptive connecting mechanism replacement force system conversion tool which comprises a main cable anchoring head lower slip, a main cable anchoring head upper slip, a main cable anchoring head rubber pad, an upper chord member lower slip, an upper chord memberupper slip, an upper chord member rubber pad, an upper chord member connecting steel plate, reflecting surface supporting channel steel, a reflecting surface supporting column inner conical surface seat, a reflecting surface supporting nut, a reflecting surface supporting column and a tensioning mechanism. According to the invention, the FAST reflecting surface unit self-adaptive connecting mechanism replacement force system conversion tool can assist replacement of a reflecting surface unit self-adaptive connecting mechanism, has low influence on the stress on an original structure, achievesrapid replacement of the self-adaptive connecting mechanism, is low in manual operation intensity, rapid in progress and free of damage on the original reflecting surface, and meets the maintenance requirement of the reflecting surface unit.

Description

technical field [0001] The invention relates to the technical field of FAST radio astronomy telescopes, in particular to a force system conversion tool for replacing an adaptive connection mechanism of a FAST reflector unit. Background technique [0002] The Five-hundred-meter Aperture Spherical radioTelescope (FAST) is a major scientific device during the 11th Five-Year Plan period in my country and the largest single-aperture radio telescope in the world. It has three independent innovations: using Guizhou's natural karst The pit is used as the platform site, the reflective surface for active deformation, and the flexible light feed source supported by six cables dragged in parallel. [0003] The FAST reflective surface uses a flexible cable net as the main supporting structure and a key component for active deformation. The cable network structure includes 6670 main cables, 2225 down cables and 2225 cable network nodes. Each pull cable is connected to a hydraulic actuato...
