Problems solved by technology

[0004] At present, space devices generally install components with cables on fixed parts, and the cables are fixed along the fixed points of the structure; or reserve enough linear and arc-shaped cables near the moving mechanism to release enough Follow the movement space of the mechanism; these cable fixing methods do not meet the cable management requirements of the large-stroke reciprocating movement of the later space device and the moving parts with multiple or multiple cables
[0005] In addition, the linear motion components of the space device mostly adopt the screw transmission mode, and the screw nut is loaded hard,

Abstract

The invention relates to an unfolding and folding movement device with a cable arrangement function and a load test device.The unfolding and folding movement device comprises a cable arrangement mechanism, an unfolding and folding driving mechanism, a locking mechanism and at least two unfolding platforms which are sequentially hinged through hinges, every two adjacent unfolding platforms are unfolded under driving of the unfolding and folding driving mechanism, and a linear supporting platform is formed; a movable pulley assembly, a fixed pulley assembly, a folding and unfolding assembly and an X-axis movement assembly capable of moving along the linear supporting platform are arranged on each unfolding platform, the fixed pulley assembly and the movable pulley assembly are sequentially arranged in the movement direction of the X-axis movement assembly, and the movable pulley assembly is slidably connected to the unfolding platform; one end of the first force-bearing steel wire rope is connected with the X-axis movement assembly, a cable of the X-axis movement assembly and the first force-bearing steel wire rope are gathered and wound on the fixed pulley assembly and the movable pulley assembly, and the other end of the first force-bearing steel wire rope is fixed on the unfolding platform; one end of a second bearing steel wire rope is connected with the movable pulley assembly, and the other end is connected to a retracting assembly.

Description

technical field [0001] The invention relates to the technical field related to spatial motion, in particular to an unfolding and retracting motion device and a load test device with a cable arrangement function. Background technique [0002] With the development of space science and space technology and the continuous exploration of space by human beings, more and more space experiments need to be carried out. Especially with the completion of the space station and the explosive growth of the number of satellite launches, the types of space motion devices that space science experiment loads need to rely on are developing in the direction of diversification, basicity, long life, and scalability. Space launch missions have the characteristics of shortage of launch volume, launch weight, power supply, and communication resources. The space environment has environmental characteristics such as high and low temperature alternating, high vacuum, strong radiation, and space debris ...
