Abstract

The invention relates to spacecraft space environment simulation equipment, and discloses a hoisting and shifting device for the cold screen of a spacecraft radiation refrigerator, comprising: the heat sink of the spacecraft space environment simulation equipment is installed inside a vacuum container through a mounting frame, according to the invention, The device also includes: a hoisting slide rail is installed on the installation frame, and a roller limit device is installed at one end; hoisting rollers are installed in the slide rail of the hoisting slide rail, and an adjustable hoisting device for hoisting a large-size cold screen is installed on the lower part of the hoisting slide rail. screw. The invention solves the problem of multi-angle hoisting and displacement of the cold screen inside the vacuum container of the spacecraft space environment simulation equipment, achieves the beneficial effect of improving the reliability of the test equipment, and effectively prevents the cold screen from damaging the surface honeycomb structure due to careless installation operations.

Description

technical field [0001] The invention relates to space environment simulation equipment for spacecraft, in particular to a hoisting and shifting device for a cold screen of a radiation refrigerator of a spacecraft. Background technique [0002] Because the radiation coolers of different satellite infrared detection and remote sensing instruments are installed at different angles during the test, correspondingly, the installation angle of the cold screen must also be adjustable. The cold screen generally consists of three parts, including the cold screen body, honeycomb and hoisting device. The body of the cold screen is generally made of stainless steel and installed on the honeycomb structure. [0003] In the past, the weight of the cold screen was generally relatively light, only tens of kilograms, and the cold screen could be shifted by carrying it on the shoulder and hand. The screen is relatively easy to damage the honeycomb structure, thereby affecting its surface emi...
