Example Embodiment

[0038] Example 1

[0039] See Figure 1-Figure 5 , The separation plug extraction device of this embodiment is composed of the following components:

[0040] The base (1) is used to provide installation positions and support for other parts, and it includes an integrally formed horizontal part (11), a first vertical part (12) and a second vertical part (13), wherein the first vertical part The straight portion (12) and the second vertical portion (13) are located above the horizontal portion (11), and the first vertical portion (12) is located in the middle of the horizontal portion (11), and the second vertical portion (13) is located An edge of the horizontal part (11); in addition, the first vertical part (12) is connected with a side part (14) along the edge of the horizontal part (11), the side part (14) and the horizontal part (11) and The first vertical parts (12) are vertical, see image 3 ;

[0041] The pin puller (7) is fixedly connected to the first vertical portion (12...

Abstract

The invention discloses a device for pulling and separating a split plug (10). The device consists of a base (1), a ratchet sleeve (2), a central pivot (3), a fastener (4), a flat spiral spring (5), a turning wheel (6), a pin puller (7), a steel wire rope (8) and a collecting tube (9). When the split plug (10) is separated, the pin puller (7) acts to pull a pin, the turning wheel (6) is pushed to rotate under the action of the elasticity of the flat spiral spring (5) so as to pull the steel wire rope (8), the steel wire rope (8) acts on the split plug (10) to make the split plug (10) unlocked and retreat, the split plug (10) is finally fixed in the collecting tube (9), and the split plug (10) is pulled, separated and collected. The device realizes three functions of pulling and unlocking the split plug, recycling in a large travel and finally collecting and fixing, and has the advantages of large work margin, simple operation, high adaptability, safety, reliability and the like.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a device for removing a separation plug or other separation devices, especially a device suitable for removing a separation plug during space flight. Background technique [0002] With the development of aerospace technology, especially the needs of the current lunar exploration project, the aerospace vehicle needs to realize the separation of multiple devices and multiple compartments during the mission cycle. A very important link in these separation processes is the separation of the separation plug. Separation is generally carried out under conditions of weightlessness. In the lunar exploration mission, due to the need to ensure a safe space for separation, the separation plug needs to be far away from the original position after separation. At present, there is a need for a detachment device for the separation plug, which needs to simultaneously complete the three functi...
