As a preferable aspect of the present invention, the hinge type release nut unlocking structure is used for separating the rocket core stage from the booster.
Example (b):
the structure of the present invention is as described in fig. 1 and 2. The hinge type separating nut unlocking structure comprises a pin 1, a sliding cylinder 2, a chassis 3, a connecting rod 4, a nut 5, a hinge type split nut 6, a damping ring 7, a detonating joint 8, a screw rod 9, a pin 10, a sealing ring 11 and a detonating cord 12. The hinge type split nut 6 is connected with the screw rod 9 through trapezoidal threads, and the sliding barrel 2 circumferentially restrains the hinge type split nut 6. The hinged split nut 6 is connected to the connecting rod 4 by a pin 10. The chassis 3 is used for installation and positioning. The hinge type separating nut unlocking structure mainly plays a role in connecting a booster of a carrier rocket with a core-level structure and unlocking at the separating moment.
The connection function is as follows: 12 connecting rods 4 are connected with the core-level structure through nuts 5. The other end of the connecting rod 4 is connected with a hinge type split nut 6 through a pin 10 in an interference fit mode, the hinge type split nut 6 is connected with a screw rod 9 through a trapezoidal thread, and the screw rod 9 is connected with a booster of a carrier rocket through a ball head ball socket structure to complete load transfer.
Unlocking function: when the sliding cylinder is unlocked, the detonator arranged on the detonating joint 8 detonates two independent detonating cords in the annular cavity of the screw 9 to generate detonation, and the sliding cylinder 2 is pushed to move to the left side. The detonation pushes the sliding barrel 2, as shown in fig. 3, overcomes the frictional resistance between the sliding barrel 2 and the hinge type split nut 6, shears the pin 1 and moves towards the boosting end, and unlocks the circumferential constraint of the split nut 6. The split nut 6 rotates around the pin 10 and is disengaged from the thread of the screw 9, and the screw 9 is separated as shown in fig. 4. After separation, the sliding barrel 2 and the screw 9 are far away from the booster, and the structure of the connecting rod 4 and the split nut 6 continues to move along with the core stage. In order to prevent the sliding barrel 2 from flying out of the device and damaging the equipment on the arrow, a damping ring 7 is designed to capture the moving sliding barrel 2. The damping ring 7 is shown in fig. 5.
The design of the whole structure takes strong connection and weak unlocking as concepts. The hinge type split nut 6 and the screw rod 9 are connected through trapezoidal threads to carry, the hinge type split nut 6 is circumferentially restrained through the sliding barrel 2, and the circumferential restraining force is only a small component of axial pulling load. The bearing structure is designed to greatly improve the bearing efficiency compared with the traditional material cutting type explosive bolt structure and the medicine ring assembly structure. During unlocking, the sliding cylinder 2 is pushed to move through the flexible detonating cord, the friction force between the sliding cylinder 2 and the screw 9 is overcome, and release of circumferential restraint is completed. Compared with circumferential restraining force, the overcome friction force is much smaller. Therefore, strong connection and weak unlocking are really realized through twice conversion of the axial pulling load. Meanwhile, in order to avoid accidental unlocking of the device caused by mechanical environments such as vibration, the sliding cylinder 2 is connected with the screw rod 9 through the two pins 1, so that the mechanical environment adaptability of the device is improved, and mistaken unlocking caused by external mechanical environments such as vibration is prevented.
When the hinge type separation nut device is used for separation, the sliding barrel 2 is pushed by acting of the detonating cord to shear the pin 1, the friction force between the sliding barrel 2 and the screw 9 is overcome to move, and the circumferential constraint of the split nut 6 is unlocked. A two-stage step structure is adopted between the screw 9 and the sliding barrel 2, and two annular cavities are formed after installation. A flexible detonating cord is installed in each cavity. The detonating cord is led out through the detonating joint 8 after being bent twice through a channel on the screw 9, and each detonating cord adopts two detonators for redundant detonating. The design of the double detonating cords and the four detonating devices realizes redundancy from the link of the final actuating unit of the initiating explosive device, and greatly improves the working reliability of the product. Meanwhile, the two detonating cords are staggered in a spatial difference mode, and the mutual influence during working is reduced. And, look at from the unblock mechanism, two explosive fuse during operation all have and push sliding barrel 2 to same direction, and both effects gain each other, avoid because the work effect of two explosive fuse produces negative effects each other by sympathetic detonation, the separation ability of every cable weakens. Meanwhile, a sealing ring is arranged on the connecting surface of the sliding cylinder and the connecting rod, so that the airtightness of a detonation action space is enhanced, and the detonation work efficiency is improved.
Those skilled in the art will appreciate that those matters not described in detail in the present specification are well known in the art.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make variations and modifications of the present invention without departing from the spirit and scope of the present invention by using the methods and technical contents disclosed above.
