Abstract
The invention discloses a parachute cabin separating mechanism, which uses a pin pushing device as a separating device of a parachute cabin system, and uses a shear screw as a connecting device, when the pin pushing device ejects out and acts on a transfer shaft, the shear screw breaks, so that a parachute cabin cover and a parachute cabin cover can be normally separated, the corresponding separating speed is obtained, and the parachute cabin separating mechanism has the advantages of simple structure and small assembly volume, thereby achieving the purpose of miniaturization of parachute cabin design; meanwhile, as the ejector is a closed ejector, the initiating explosive device is completely positioned in the ejector, and the initiating explosive device does not cause any damage to the parachute when detonating, thereby improving the success rate of parachute opening.
Description
Technical Field
The invention belongs to a parachute cabin separation technology, and particularly relates to a parachute cabin separation mechanism.
Background
When the parachute cabin system works, the parachute cabin cover is required to be separated from the parachute cabin body, a certain separation speed is formed, and therefore, the parachute stored in the parachute cabin is pulled out and opened, and load is decelerated. The traditional parachute cabin separating mechanism generally adopts a spring clip device with initiating explosive devices at the joint of a parachute cabin cover and a parachute cabin body, a parachute drum is arranged in the parachute cabin, when the parachute cabin system works, the initiating explosive devices detonate to drive the spring clip device to open, the parachute cabin cover and the parachute cabin body are unlocked, and meanwhile the parachute drum acts to eject the parachute cabin cover and the parachute. The structure is complex, flame is likely to damage the parachute when the initiating explosive device acts, so that the parachute can not be opened, and the structure is large in size and is not beneficial to the miniaturized design of the parachute cabin system.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a parachute kit separating mechanism.
The invention realizes the above purpose through the following technical scheme:
a parachute cabin separating mechanism comprises a parachute cabin body and a parachute cabin cover covered on the parachute cabin body;
the umbrella cabin body is fixedly connected with a switching shaft, the umbrella cabin cover is fixedly connected with a closed pin pushing device, the pin pushing end of the closed pin pushing device is opposite to the switching shaft, and the switching shaft is connected with the umbrella cabin cover through a shearing screw.
As a technical scheme selected by the patent, a detachable connecting structure connected through a flange is arranged between the switching shaft and the parachute cabin body.
As a technical scheme of this patent selection, the one end of changeover axle with umbrella cabin body fixed connection, and the blind hole has been seted up to the other end, the promotion of closed promotion ware pops out the end and arranges in the blind hole.
As a technical scheme selected by the patent, a detachable connecting structure fixedly connected through a connecting bolt is arranged between the closed type pin pusher and the umbrella cabin cover.
The invention has the beneficial effects that:
according to the invention, the ejector is used as a separating device of the parachute cabin system, the shear screw is used as a connecting device, and after the ejector pin of the ejector ejects and acts on the switching shaft, the shear screw breaks, so that the parachute cabin cover and the parachute cabin body can be normally separated, and the corresponding separation speed is obtained, and meanwhile, the parachute cabin system has the advantages of simple structure and small assembly volume, thereby achieving the purpose of miniaturization of parachute cabin design; meanwhile, as the ejector is a closed ejector, the initiating explosive device is completely positioned in the ejector, and the initiating explosive device does not cause any damage to the parachute when detonating, thereby improving the success rate of parachute opening.
Drawings
FIG. 1 is a cross-sectional view of a parachute bay separation mechanism of the present invention;
in the figure: 1-a closed-type pin pusher; 2-shearing screws; 3-umbrella hatch cover; 4-an adapter shaft; 5-umbrella cabin body.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
referring to fig. 1, the invention comprises an umbrella cabin 5 and an umbrella cabin cover 3 covered on the cabin; the umbrella cabin body 5 is fixedly connected with the switching shaft 4, the umbrella cabin cover 3 is fixedly connected with the closed type pin pushing device 1, the pin pushing and ejecting end of the closed type pin pushing device 1 is aligned with the switching shaft 4, and the switching shaft 4 is connected with the umbrella cabin cover 3 through the shearing screw 2.
The closed type pin pusher 1 is a relatively mature technology in the prior art, an initiating explosive device and an initiator for initiating the initiating explosive device are arranged in an inner closed space of the closed type pin pusher 1, after the initiating explosive device is initiated, the pin in the closed type pin pusher 1 can be quickly ejected, and the closed type pin pusher 1 is not described in the patent. In this patent, the shear screw 2 for connecting the umbrella cabin cover 3 and the adapter shaft 4 needs to be subjected to mechanical calculation, and the mechanical strength is greater than the load that needs to bear in the working process of the umbrella cabin system and is less than the thrust load generated when the closed type pin pusher 1 acts.
As a technical scheme selected by the patent, a detachable connecting structure connected through a flange is arranged between the adapter shaft 4 and the parachute cabin body 5, so that the assembly and maintenance are convenient.
As a technical scheme that this patent selected, the one end and the parachute cabin body 5 fixed connection of changeover shaft 4, and the blind hole has been seted up to the other end, and the pushing pin of closed type pushing pin ware 1 pops out the end and arranges in the blind hole, and the design of blind hole can prevent to push out the pin and skid when acting on changeover shaft 4.
As a technical scheme selected by the patent, a detachable connecting structure fixedly connected through a connecting bolt is arranged between the closed type pin pusher 1 and the umbrella cabin cover 3 so as to facilitate assembly.
The working principle of the invention is as follows:
when the parachute cabin cover 3 is required to be separated from the parachute cabin body 5, initiating explosive devices in the closed type ejector 1 are controlled to detonate, the ejector pins of the closed type ejector 1 are rapidly ejected towards the switching shaft 4, and the shearing screw 2 at the switching shaft 4 is broken by shearing force, so that the parachute cabin cover 3 and the parachute cabin body 5 are unlocked, the parachute cabin cover 3 and the parachute cabin body 5 are rapidly separated under the action of thrust load, a certain separation speed is generated, and the parachute is pulled out.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
