Combined operation platform structure used for large spacecraft thermal vacuum tests

Abstract

The invention discloses a combined operation platform structure used for large spacecraft thermal vacuum tests. The structure comprises: four operation platform components that are in cross and symmetrical arrangement around a circumference, four butting frame components for fixing adjacent operation platform components, and several telescoping pedal mechanisms. The plane of the operation platform structure is a regular octagon and integrates the operation platform components through the butting frame components. Specifically, the bottoms of each fixed platform layer around the space surrounding a built-in spacecraft are connected to the telescoping pedal mechanisms through tracks, so that operating personnel can operate a spacecraft by adjusting the extension distance of the telescoping pedals. During application of the combined operation platform structure used for large spacecraft thermal vacuum tests, the operation platform is hoisted into a vacuum container by means of pieces and then combined. The operation platform satisfies all operation requirements, and an enough safe distance is kept between the operation platform and an infrared heating cage. The operation platform of the invention can also guarantee the implementation of each operation as well as the security of operating personnel, and has enough strength and rigidity.

Description

technical field [0001] The invention relates to a combined operating platform structure for large-scale spacecraft thermal vacuum test, which belongs to the field of vacuum thermal test. Background technique [0002] The target aircraft is a new generation of manned spacecraft in my country, and it is a large spacecraft with a low orbit and an on-orbit life of 2 years. The target aircraft must conduct a vacuum thermal test in KM6 (large-scale spacecraft thermal vacuum test equipment): first, conduct thermal control modification, and then conduct thermal related tests, including ground temperature adjustment test, thermal balance test of autonomous flight section and thermal balance test of assembly operation section , to verify the thermal environment and the control capability of the thermal control system of the target aircraft in the standby stage, autonomous operation stage and composite operation stage. The target aircraft is currently the largest and most complex spac...

Problems solved by technology

[0003] The operating platforms used for large-scale spacecraft experiments are mostly square structures in cross-section, and are generally composed of four parts through a docking frame. The size of the currently used operating platforms can no longer meet the requirements of the target aircraft experiments, and the square structure cannot be fully utilized. The interior space of KM6, the aisles and stairs of the platform are relatively narrow, which is not convenient for people to move around; all the movable platforms of the operating platform are flap structures, and the operation is more complicated
