According to the parallel tearing device provided by the invention, the effect of a cabin leaving force generated by two groups of bearings through extrusion forces in the prior art is replaced, the weight of a seat is obviously reduced, the stability of the cabin leaving force and the reliability and the safety of a system are improved, and meanwhile, the requirement on a stabilizing force of an ejection seat in the cabin leaving process is met.
Description
Technical field
The invention belongs to extraordinary industrial textile, relate in particular to a kind of for the stable parallel tear device of Aircraft Ejection Seat deliver from vault.
Background technology
At present at home in the fighter plane ejection survival seat fire deliver from vault stabilizing mechanism, for the weight of mitigation system with reduce volume, further improve the in-use performance of relevant weaponry, the stable control mechanism of the tear device that has proposed to adopt tear-strap during as the seat fire deliver from vault.Utilize the textile material softness can around characteristic and certain limit in tear intensity of load, regulate material as a kind of new form-drag of flight equipment, in airplane catapult Lifesaving chair deliver from vault stabilizing mechanism, play good control action as the use of shock absorber.Though tear-strap is textile material, its special structure is extremely important, because the mode of tearing of tear-strap and tear powerful very great to the supporting weaponry performance impact of institute.The type of external tear-strap there is not yet the parallel report of tearing, and only has a kind of form of tongue tear, and it is torn brute force and also only has 30N, the stability force 2000N in the time of can not satisfying the ejection-seat deliver from vault far away.And at present both at home and abroad during the ejection-seat deliver from vault its stability force be the effect that reaches the control stability force by two groups of bearings by the extruding rope, because the diameter of rope is sometimes inhomogeneous and have a fault, cause that not only stability force is inhomogeneous, the phenomenon that also occurs stablizing fracture of rope when serious, and system weight is very heavy.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of stability force evenly and tear powerful large parallel tear device.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
Parallel tear device, it is characterized in that, it comprises tears bar and the epipelagic zone that is parallel to each other and lower floor's band, the described bar of tearing is arranged between described epipelagic zone and the lower floor's band, the described axis of tearing bar and described epipelagic zone are vertical with the length direction of lower floor's band, described epipelagic zone is connected with lower floor by many connection leads and is connected, every connection lead extends with the mode of twining epipelagic zone and the lower floor band length direction along epipelagic zone and lower floor's band, and many connection leads are arranged along the Width of described epipelagic zone and lower floor's band.
In the such scheme, the described length of bar of tearing is more than or equal to the width of described epipelagic zone and lower floor's band.
In the such scheme, every determined plane of connection lead is vertical with the described axis of tearing bar.
In the such scheme, described many connection leads are uniformly-spaced arranged along the Width of described epipelagic zone and lower floor's band.
In the such scheme, the described material of tearing bar is metal.
In the such scheme, the described diameter of tearing bar is 8mm.
In the such scheme, described epipelagic zone and lower floor's band are double-deck plain weave construction, and warp, the parallel raw material of described epipelagic zone and lower floor's band are 278dtex, and strength of filament is 7.2CN/dtex.
In the such scheme, the warp of described epipelagic zone and lower floor's band is combined as 278dtex * 3 * 2, and parallel is combined as 278dtex * 6.
In the such scheme, the radical of described connection lead is the 14-18 root.
In the such scheme, the brute force of tearing of described parallel tear device is 1700-2200N.
Principle of the present invention is: the present invention utilizes jacquard loom that epipelagic zone and lower floor's band are made into one by connection lead with it, between epipelagic zone and lower floor's band, penetrate metal and tear bar, epipelagic zone and lower floor's band are in motion process, tear bar by metal and cut off connection lead, produce stable tear edge, tear edge can be by radical and the powerful effect that reaches control deliver from vault stability force of regulating connection lead.
Compared with prior art, the beneficial effect obtained of the present invention is:
Parallel tear device of the present invention has replaced being produced by squeese pressure by two groups of bearings in the prior art effect of deliver from vault power, alleviated significantly seat-weight, reliability and the safety of stability and the system of deliver from vault power have been improved, the stability force requirement when having satisfied simultaneously the ejection-seat deliver from vault.
Description of drawings
The birds-eye view of the parallel tear device that Fig. 1 provides for the embodiment of the invention.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples, and certain following embodiment should not be construed as limitation of the present invention.
As depicted in figs. 1 and 2, the parallel tear device that it provides for the embodiment of the invention, it comprises that the epipelagic zone 8 and the lower floor that tear bar 10 and be parallel to each other are with 9.
Tear that bar 10 is arranged on epipelagic zone 8 and lower floor is with between 9.The axis of tearing bar 10 and epipelagic zone 8 and lower floor are vertical with 9 length direction.The length of in the present embodiment, tearing bar 10 more than or equal to epipelagic zone 8 and lower floor with 9 width.In the present embodiment, every connection lead 7 determined planes are vertical with the axis of tearing bar 10.In the present embodiment, the material of tearing bar 10 is metal, and diameter is 8mm.
In the present embodiment, the radical of connection lead 7 is the 14-18 root.The raw material choose 278dtex of connection lead 7.Radical by regulating connection lead 7 and powerful adjustable parallel tear device tear brute force, thereby reach the effect of control deliver from vault stability force.In the present embodiment, the brute force of tearing of parallel tear device is 1700-2200N.
The working process of this parallel tear device is: during ejection survival seat fire deliver from vault, can make epipelagic zone 8 and lower floor be with 9 alongst motions, keep static and tear bar 10, therefore epipelagic zone 8 and lower floor are with 9 in motion process, tear bar 10 and can cut off connection lead 7, make epipelagic zone 8 and lower floor be with 9 separately, thereby produce the stable brute force of tearing.
Need to prove, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from aim and the scope of technical solution of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
