Description
Technical field
The present invention relates to a kind of coring soft bag and its manufacture method.
Background technology
China Lunar Exploration Program enter comprehensively " around, fall, return " third phase of three-step-march development plan, planned before 2017
Execute No. five tasks of the goddess in the moon afterwards, nobody samples returns automatically to realize lunar soil, the moon that realization is with historically new significance is drilled-taken
Core-return experiment.There will be very many technological difficulties in this experimentation, wherein drill through the structure of sampling coring soft bag
Design, product weaving are one of them with functional realiey.Drilling through sampling coring bag needs to effectively complete obtaining for lunar soil sample
Take and layer reason keeps work, lunar soil sample is wrapped in coring flexible pouch and flexible pouch end is reliably sealed, protected
High core-taking rate is demonstrate,proved, sample is not leaked, is not fallen sample, layer reason conservation degree height, and, whole coring device must have very high environment to adapt to
Property, can under the severe rugged environments such as lunar surface high and low temperature alternative, low gravitation, lunar dust reliably working, and extract with follow-up coring soft bag
And winding integer action forms good interface, it is that integer winding is made sufficient preparation.
Carry core drawstring to there is connection member mainly and carry the effect of power, be to drill through the requisite part of sampling apparatus,
Including with soft bag connection end and coring mechanism connection end.The soft bag winding reliable drawing work(for carrying core drawstring and complete to propose core, shaping
Can, it is necessary guarantee that location of the coring procedure is smoothed out.Its light weight, intensity are big, effectively avoid in transmitting and landing mission
Resonance, be development mechanism be smoothed out necessary guarantee is provided.
In actual condition, if coring soft bag is carried out external connection with core drawstring is carried, easily cause end at the embedded place of soft bag
Mouth is shunk so that stress concentration, causes risk of breakage.Therefore by coring soft bag and carry core drawstring carry out integrated structure design and
Manufacture can at utmost meet lunar soil sampling task.
Content of the invention
The invention aims to reducing coring soft bag and carrying core drawstring junction being also easy to produce stress concentration, cause to rupture
Problem, and provide and put forward the integral structure coring soft bag and its manufacture method of core drawstring containing hollow rope outer cladding.
The present invention puies forward the integral structure coring soft bag of core drawstring by the flexible coring with yarn beam containing hollow rope outer cladding
Bag and hollow rope composition, in the bottom connection yarn beam of tubular flexibility coring bag, yarn beam extended by the warp thread in flexible coring bag and
Into the outer surface reciprocal knitting in yarn beam is coated with hollow rope.
The manufacture method of the integral structure coring soft bag that the present invention carries core drawstring containing hollow rope outer cladding follow these steps to
Realize：
First, fibrous warps are carried out warping process, tubular flexible fabric is gone out using loom plain weave then, braiding terminates
Warp thread is carried out from loom heddle (heald) back yarn process afterwards, back yarn boundling obtains yarn beam, then yarn beam is uniformly around on i-axis, obtains
To the flexible coring bag with yarn beam；
2nd, it is high-speed knitter forming hole between 8 ingot～36 ingots by the flexible coring bag with yarn beam by number of spindles, with
Yarn beam is stock core, with the twisting of batch fiber, dividing sinker in flexible coring bag, and is assemblied on the braiding ingot of high-speed knitter, outsourcing
Cover fiber and be divided into two group braided wires, the weaving direction of two group braided wires is interleaved with each other on the contrary and is coated on strand core, obtains hollow rope outsourcing
Cover；
3rd, the connector for being located at flexible coring bag and yarn beam junction is tightened to form sealing using sealing line, then will step
Rapid two hollow rope outer cladding is reversely woven to sealing line from 2～5cm of sealing starting to carry out cladding braiding to sealing part
Until yarn beam end, cut-out, knot after dispensing, complete the integral structure coring soft bag for carrying core drawstring containing hollow rope outer cladding
Manufacture.
Coring soft bag is tied by integrated coring soft bag provided by the present invention with core drawstring two parts functional unit is carried
Structure integrated design and manufacture, drill through the introducing of other functions component in mechanism so as to reduce coring, reduce junction fracture
Risk, makes coring soft bag with the fracture tensile strength for carrying core drawstring junction and reaches more than 2000N, disclosure satisfy that boring coring work(
The requirement of energy, and with excellent reliability.At the same time, the manufacturing process of the coring soft bag is simple, easy to install,
Manufacture and assembly are carried out by existing equipment.Therefore, the integrated coring soft bag that the present invention is provided has very high practical value.
