Abstract

A passive space lock release device, comprising a shell, a lock hook assembly, a sliding pin, a pressure plate, an operating rod, an end cover, a strap assembly, a bottom cover, and a tension spring assembly; a set of locks is installed in a groove outside the shell Hook assembly; one end of the lock hook of the lock hook assembly is provided with a waist-shaped hole, and a sliding pin is installed in the waist-shaped hole, and each pressure plate slides in the pressure plate sliding groove to form a pin movement pair; the end cover is fixedly installed at the port of the cylinder part , each pressure plate is connected with the end cover through the tension spring assembly; a number of operating rods are evenly distributed on the strapping assembly along the circumferential direction; the strapping assembly is sleeved outside the lock hook assembly, and the strapping structure is provided with explosive bolts, which are unlocked by the explosive bolts; The bottom cover is installed on the casing to cover the strap assembly and the lock hook assembly. The side wall of the bottom cover is provided with an operating rod movable groove along the longitudinal direction, and the operating rod protrudes from the operating rod movable groove. The present invention can realize the functions of manual locking and releasing and automatic releasing of pyrotechnics, and in cooperation with the locked piece, the present invention has the functions of electric unlocking and releasing.

Description

technical field [0001] The invention belongs to the technical field of aerospace vehicles, and relates to a space locking and releasing device. Background technique [0002] The on-orbit components or extravehicular tests of each cabin section need to be realized by the use of extravehicular manipulator products, and the extravehicular manipulator products need to be compressed on the cabin by various compression mechanisms in the launch section of the cabin. On the one hand, ensure that the outer envelope size of each cabin section is as small as possible, and does not exceed the envelope of the launch vehicle fairing; Not damaged during launch. After the module enters orbit with the rocket, various extravehicular mechanism products such as the robotic arm need to be automatically released and moved to the designated position to complete the subsequent tasks. At present, the automatic release products mainly include mature solutions and products such as explosive bolts, s...
