Passive space locking and releasing device

Abstract

A passive space locking and releasing device comprises a shell, a lock hook assembly, a sliding pin, a pressing plate, an operating rod, an end cover, a wrapping belt assembly, a bottom cover and a tension spring assembly. A group of lock hook pieces is mounted in each groove in the outer side of the shell; a kidney-shaped hole is formed in the end portion of one end of a lock hook of the lock hook assembly, a sliding pin is installed in the kidney-shaped hole, and pressing plates slide in pressing plate sliding grooves to form a pin kinematic pair. The end cover is fixedly mounted at a port of the cylinder piece, and each pressing plate is connected with the end cover through a tension spring assembly; the plurality of operating rods are uniformly distributed on the belting assembly along the circumferential direction; the lock hook assembly is sleeved with the wrapping tape assembly, an explosive bolt is arranged on the wrapping tape structure, and unlocking is achieved through the explosive bolt. The bottom cover is installed on the shell and covers the belting assembly and the lock hook assembly, an operating rod moving groove is formed in the side wall of the bottom cover in the longitudinal direction, and the operating rod extends out of the operating rod moving groove. Manual locking and releasing can be achieved, the initiating explosive device automatic releasing function is achieved, and in cooperation with a locked piece, the electric unlocking and releasing function is achieved.

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...
