Abstract

The C-type carbon fiber support tube roll-out device for space-expanded parabolic cylinder antenna belongs to the technical field of support structure for space-expanded parabolic cylinder antenna, and solves the current problem that it is difficult to uniformly curl and unroll the C-type carbon fiber support tube. It includes a roll-out mechanism and an orientation mechanism. The roll-out mechanism includes a reel, and a shaft frame plate is arranged at each end of the reel; one end of the reel is connected with a drive system, and the speed of the reel is set at 2 revolutions per minute; around the reel There are multiple pressing rods that are consistent with the direction of the reel, the drive system includes a motor and a reducer, and the motor is connected to the reducer; the orientation mechanism includes two or more positioning plates, and each positioning plate is set There is a round hole, and a C-shaped hole is arranged around the round hole. There are multiple sets of top wires arranged in pairs on the inside and outside of the C-shaped hole. Carbon fiber support tube.

Description

technical field [0001] The invention belongs to the technical field of supporting structures for space-deployed parabolic cylinder antennas, and in particular relates to a C-shaped carbon fiber support tube roll-out device for space-deployed parabolic cylinder antennas. Background technique [0002] The C-type carbon fiber support tube is used to support the reflective surface of the parabolic antenna in space. It has many advantages such as suitable rigidity, easy curling and stretching, and light weight. It is an ideal material, but it is currently difficult to uniform the C-type carbon fiber support tube. Curling and unfolding affect the use effect of the C-shaped carbon fiber support tube. Contents of the invention [0003] The purpose of the present invention is to solve the problem that it is difficult to uniformly curl and unfold the C-type carbon fiber support tube at present, and provides a C-type carbon fiber support tube roll-out device for spatially expanding t...
