Description
Technical field
The present invention relates to a kind of docking facilities of space flight, more particularly to a kind of extend out gradual change inflatable pair for space
Connection device.
Background technology
With the development of aerospace industry, various space equipments are more and more, such as various space satellites, space station, space flight
Aircraft etc..These space equipments are run on high to be needed to carry out various change operation in some cases, for example satellite is carried out
In-orbit docking, to realize the capture of extraterrestrial target, posture adjustment, become the operation such as rail and transfer.
Existing docking mechanism generally uses mechanical docking mechanism, there are it is complicated, transmitting size is big, control requires
The shortcomings of height, control difficulty are big, easy damaged docking target.
To solve the above-mentioned problems, patent document proposes that inflatable docking mechanism, such as number of patent application are
The application for a patent for invention of " 201510139308.9 ", discloses a kind of front end and expands formula inflation docking mechanism, comprising support tube and
Termination is expanded, expansion termination is arranged on the front end of support tube, and expansion termination is set with support tube center alignment, expansion termination and branch
Stay tube is fixedly connected, and support tube and expansion termination are all flexible gas-filled structures, and the outside diameter of support tube is less than expansion termination and support
The length of most long straight line distance on the parallel section in the cross section of pipe；Longitudinal volume is provided with the side of support tube
Spring.This structure uses inflatable structure, have it is simple in structure, be easy to docking, docking operation control requires that low, control mode is simple
The advantages such as singly, transmitting is small, light-weight, cost is low, still, expansion termination are arranged on the front end of support tube, and support tube is to swollen
The underbraced of swollen termination, makes expansion termination be not sufficiently stable after inflation is docked, and since expansion termination is one, it is most suitable
Suitable rate of tension corresponds to one, so the diameter of the docking object most adapted to can only be one, which limit the docking mechanism
The scope of application.
The content of the invention
The purpose of the present invention is that to solve the above-mentioned problems and provides a kind of docking and stablize, applied widely be used for
Space extends out gradual change inflatable docking facilities.
The present invention is achieved through the following technical solutions above-mentioned purpose：
It is a kind of to extend out gradual change inflatable docking facilities for space, including pipeline is docked, the first of the docking pipeline
End is provided with connecting flange, is equipped with to the direction of first end since second end multigroup block and more on the docking pipeline successively
Spacing between the group block is increasing or less and less, and block described in every group is by two block groups close to arrangement
Into being separately installed with the elastomer of tubulose between block described in two adjacent groups, the both ends of the elastomer are respectively with corresponding two
The group block is tightly connected, and the termination of the elastomer is placed between two blocks and is sealed, multiple elasticity
The elasticity of body is identical or essentially identical, and the tube wall of the docking pipeline between block described in two groups of initial and end is equipped with
The through hole being interlinked to the outside in multiple.
In said structure, block is used to install elastomer, and multiple elastomers form utricule, gas is formed after inflation after mounting
Capsule, its enlarged-diameter, realizes the close connection between the inner wall of other butt tube, so as to fulfill rapid abutting joint；Multiple bullets
Property body structure can be real with other butt tubes of corresponding diameter in the case where each elastomer is in optimum rate of tension
Now close connection.
Specifically, the block is five groups altogether, and the elastomer is four altogether, the length of four elastomers by
The second end of the docking pipeline is sequentially reduced to the direction of first end.
Preferably, the elastomer is followed successively by inner liner, bearing layer and elastic layer from inside to outside.
It is highly preferred that the inner liner is butyl rubber film, the bearing layer is aramid fiber, and the elastic layer is rubber
Glue film.
The beneficial effects of the present invention are：
The present invention makes elastomer also can be with docking after inflating by the way of elastomeric seal is installed on docking pipeline
Pipeline stabilization connects, so as to enhance the stability after whole docking facilities docking, is conducive to reliably grasp control object
Make；Using multiple increasing lengths or successively decrease and elastomer that elasticity is consistent, this docking facilities is adapted to multiple diameter not
Same docking object, so that the scope of application of this docking facilities is expanded, and in docking object less for diameter, by
The air bag formed after having more than one elastomer to inflate can be contacted with docking the inner wall of object, so it docks stability
It can further improve；This docking facilities is suitable for docking with the object-based device that docks compared with Large Diameter Pipeline hollow pipe.
