Abstract

The invention discloses a device for maintaining a compression arm on a satellite solar array, and particularly relates to the technical field of aerospace equipment parts. The device comprises a mechanical arm, wherein a power box and a positioning cylinder are arranged on the mechanical arm, a transmission mechanism, first transmission shafts and a second transmission shaft are arranged in the power box, a telescopic mechanism is connected to each first transmission shaft, and an inner hexagon wrench is connected to each telescopic mechanism; the second transmission shaft is provided with acasing and a first spring, the first spring is fixed on the second transmission shaft, the first spring covers a holder, the inner wall of the holder is provided with a compression arm wrench, a nut wrench, a compression arm lift and a photoelectric switch. The compression arm lift is positioned between the compression arm wrench and the nut wrench, and a first proximity switch and a snap ring arearranged in the positioning cylinder, and a second proximity switch is disposed on the positioning cylinder. The technical solution of the invention overcomes the problem of unlocking failure of thecompression arm on the satellite solar array, and the device can be used for maintenance of the solar array on the satellite.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a maintenance device for a compression rod of a satellite solar wing. Background technique [0002] With the exploration of the universe by human beings, aerospace technology has developed rapidly, and more and more space stations or satellites have been launched into space by human beings. If the satellite breaks down during the positioning process, the secondary deployment of the solar wing and the deployment of the communication antenna cannot be completed normally. At this time, it is necessary to use the manipulator to unscrew the shock-absorbing headgear of the pyrotechnics and pull out the compression rod. The shock-absorbing The head cover includes a positioning cylinder and two hexagon socket screws for fixing the positioning cylinder, and a lock nut (the lock nut is a hexagon nut) is threaded on the compression rod. The compression rod is actually a hexagona...
