Problems solved by technology

[0005] c. When the pyrotechnic components are disassembled, hand-held disassembly and assembly is usually used. After the pyrotechnic components work, a relatively large air pressure will be generated inside, which will push the structural parts outward. Operators also have great potential safety hazards, so it needs to be carried out after the rest time specified in the process, which cannot meet the short-term disassembly requirements

Abstract

The invention discloses an antenna locking device. A press rod and a separation nut adopt a structural positioning mode to ensure effective connection length of a thread; compared with a traditional measurement method, the length of the press rod is reduced and the connection rigid is improved when the thicknesses of antenna frames are same; and a shell and an adaptive support are directly to be positioned and reset by the separation nut, the installation accuracy of the locking device is improved, and the locking device can be repeatedly installed. Meanwhile, the invention also provides an installation and disassembly method of the antenna locking device, the method has the characteristics of easiness in assembly and adjustment, installation adjustment, safe short-term disassembly and high efficiency, and moreover, the standing time required by a fire work assembly after working is shortened.

Description

technical field [0001] The invention relates to the technical field of aerospace vehicle antennas, in particular to an antenna locking device and an assembly and disassembly method. Background technique [0002] As a new type of pyrotechnic device, the separation nut is mainly used for locking large-load satellite antennas, and can also be used for locking and separating related rocket body structures, inter-stage separation, satellite-rocket connection and separation, etc. , The application is extremely extensive, so it is highly valued by aerospace powers such as the Soviet Union and the United States. Foreign research and design of separation nuts started earlier. In the early 1980s, related low-impact, non-polluting pyrotechnic locking and releasing devices began to be used for the locking of loads such as antennas of relevant foreign satellite models and the separation of satellites and arrows. Good results have been achieved; domestic research and application in thi...
