Problems solved by technology

Many connection devices are in the form of multi-point connection. When unlocking the connection, multiple connection points are required to be unlocked simultaneously. The traditional synchronous unlocking method often uses a tensioned steel wire rope or Kevlar wire rope to bind the unlocking mechanism, and cuts the wire rope or other Release the silk rope to achieve the effect of pulling out the pin, such as 200710177803.4 and 200910122846.1. This type of method has the following disadvantages: 1. The synchronization of unlocking cannot be strictly guaranteed
2. After the flexible rope is cut off, it is difficult to manage in the state of weightlessness, and there is a risk of hooking with other moving parts
3. The installation of the rope is inconvenient, and the tension of the rope needs to be strictly controlled during the installation process
4. The rope can only be used once

Abstract

The invention discloses a four-point linkage pin pulling device which comprises a base (1), linkage rods (2), L-shaped connecting rods (3), locking pin connecting rods (4), unlocking pins (5), pin pulling springs (6), unlocking pin housings (7) and pin pullers (8), wherein the unlocking pins act synchronously; the synchronous unlocking of four groups of compression release devices is ensured; thelocking pin connecting rods, the L-shaped connecting rods and the linkage rods are mounted on the base in the connecting form; and in the unlocking state, four groups of pin pulling devices, namely the pin pullers, act synchronously, so that the compression unlocking reliability can be improved.

Description

technical field [0001] The invention relates to a pin pulling device, in particular to a four-point linkage type pin pulling device. Background technique [0002] In the field of aerospace, the connection and release of payloads and vehicles exists widely, such as stages and stages of multi-stage rockets, satellites and launch vehicles, satellites and spacecraft, solar wings and space vehicles, deployed antennas and space vehicles, and so on. Many connection devices are in the form of multi-point connection. When unlocking the connection, multiple connection points are required to be unlocked simultaneously. The traditional synchronous unlocking method often uses a tensioned steel wire rope or Kevlar wire rope to bind the unlocking mechanism, and cuts the wire rope or other Way release silk rope to realize the effect of unplugging, as 200710177803.4 and 200910122846.1, there are following shortcomings in this kind of way: 1. Can not guarantee the synchronism of unlocking str...
