Embodiment
[0042] The invention is a reverse-installation separation nut device with convenient docking operation, which eliminates the hidden danger of blind installation, simplifies the installation and inspection process, and shortens the operation time. The technical scheme of the anti-installation separation nut device of the present invention is as follows:
[0043] The anti-installation separation nut device is composed of butt bolt 1, catcher assembly 2 and separation nut assembly 3, the structure form is as attached figure 1 shown.
[0044] The head of the butt bolt 1 adopts an octagonal structure, and the front section of the head is a tapered surface. The catcher assembly 2 is composed of two parts: a catcher housing 4 with a butt bolt catch function and a catcher base 5 with both anti-installation and bearing functions. The top of the catcher housing 3 adopts an adaptive passive deformable conical surface for capturing the separated butt bolts 1, which can adapt to butt bol...

The utility model discloses a reversely-installed separation nut device convenient for butt joint operation. The reversely-installed separation nut device comprises a butt joint bolt, a catcher component and a separation nut component, wherein the catcher component is arranged on a butt joint frame at one side of the useful load, and the separation nut component is arranged on the butt joint frameat one side of the rocket; the butt joint bolt is used for connecting the catcher component and the separation nut component in order to enable the useful load to be in butt joint with a rocket; before butt joint operation, the butt joint bolt is pre-arranged in the catcher component through a clamping groove structure; and during butt-joint operation, the butt-joint bolt is pulled out of the catcher component through a tool, so that the butt-joint bolt is in threaded connection with the separation nut component. According to the reversely-installed separation nut device, the hidden danger ofmanual operation caused by blind installation operation in the reverse installation process is eliminated, repeated confirmation is not needed in the operation process, and the operation time is greatly shortened.
Description
technical field [0001] The invention relates to an anti-installation separation nut device for convenient docking operation, which belongs to the field of structural design of pyrotechnic separation devices for launch vehicles. Background technique [0002] The separation nut device is a point-type separation device widely used in the connection and separation of the payload and the docking surface of the rocket. It consists of a catcher assembly, a separation nut assembly and a docking bolt. The catcher is installed on the docking frame on one side of the payload, and the separation nut assembly is installed on the docking frame on the side of the rocket. The catcher assembly and the separation nut assembly are connected by butt bolts to realize the docking of the payload and the rocket. [0003] When the payload is docked with the rocket, under the normal operation process, the catcher assembly and the separation nut assembly are pre-installed on their respective docking f...
