Embodiment 1

[0055] The invention provides a method for replacing an adaptive connection mechanism of a FAST reflective surface unit, which includes the following steps:

[0056] installation of hanging points;

[0057] The climbing platform 8 is installed and climbed to the construction position;

[0058] Install a set of hanging baskets on both sides of the connecting mechanism to be replaced and strengthen the hanging baskets for the manned construction platform.

[0059] Flip and remove the corresponding position of the self-adaptive connection mechanism to be replaced (the 1# end shaft connector is replaced with the 0# end shaft new connector position 1 or the 0# end shaft connector is replaced with the 1# end shaft new connector position 2) reflection Small panels at corners of face elements;

[0060] Install the force system conversion device;

[0061] Adjust the position of the end axis of the reflective surface panel;

[0062] The gravity of the reflecting surface panel is tra...

Embodiment 2

[0078] Embodiment 2 provides a method for replacing the 1# connection mechanism of the FAST reflection surface unit with a 0# connection mechanism. This embodiment adds a method for replacing the 1# connection mechanism of the FAST reflection surface unit with a 0# connection mechanism on the basis of Embodiment 1. #Another technical solution of the connection mechanism, the technical features disclosed in the first embodiment are also applicable to the second embodiment, and the technical features disclosed in the first embodiment will not be described again.

[0079] The method of replacing the 1# connection mechanism of the FAST reflector unit with the 0# connection mechanism includes the following steps:

[0080] (1) The "Spiderman" slides from the position of the ring beam along the main cable to the position of the joint plate where the connection mechanism needs to be replaced, and installs the first lifting point 3, the second lifting point 4 and the third lifting point...

Embodiment 3

[0093] Embodiment 3 provides a method for replacing the 0# connection mechanism of the FAST reflector unit with the 1# connection mechanism. This embodiment adds a method for replacing the 0# connection mechanism of the FAST reflector unit with 1# on the basis of Embodiment 1. #Another technical solution of the connection mechanism, the technical features disclosed in the first embodiment are also applicable to this embodiment, and the technical features disclosed in the first embodiment will not be described again.

[0094]The main steps of replacing the 0# connecting mechanism of the FAST reflector unit with the new connecting piece of the 1# end shaft are as follows:

[0095] (1) The "Spiderman" slides from the position of the ring beam along the main cable to the position of the node plate where the connection mechanism needs to be replaced, and installs the first lifting point 3, the second lifting point 4 and the third lifting point 5, and the first lifting point 3. The ...

Abstract

The present invention relates to the technical field of FAST radio astronomy telescopes, in particular to a method for replacing an adaptive connection mechanism of a FAST reflector unit. Panel; install the force system conversion device; adjust the position of the end shaft of the reflective surface panel; transfer the gravity of the reflective surface panel to the adjacent cable body; remove the adaptive connection mechanism to be replaced; install a new adaptive connection mechanism and fasten it with the node plate ; The force system conversion device removes and restores the installation of the small panel at the corner of the reflector unit. This method does not change the force system of the original structure during the replacement process of the self-adaptive connection mechanism of the reflection surface unit, and has little influence on the force of the original structure, and realizes the rapid replacement of the self-adaptive connection mechanism of the reflection surface unit, with low manual labor intensity and fast progress , no damage to the reflecting surface unit, can be used repeatedly, facilitates standardized construction, high work efficiency, and low construction cost.

Description

technical field [0001] The invention relates to the technical field of FAST radio astronomy telescopes, in particular to a method 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 actuator and anchored to the ...
