Description

Technical Field

[0001] The invention relates to the field of bomb-dropping devices, and in particular to an integrated tail cover for loading and unloading bombs. Background Art

[0002] Mine suppression is an important anti-mine means of the navy today. When a minesweeper finds a mine, it can release a mine-sweeping bomb through the bombing device on the side of the deck to eliminate the potential threat. Figure 1 As shown, the current bomb delivery system consists of several canisters, each of which can be loaded with a mine-killing bomb from the rear end. The bomb's fuse is connected to the bomb delivery system's tail cover, which also supports the bomb and, in conjunction with other devices, stabilizes the bomb within the canister. Currently, the bomb delivery system uses manual loading and unloading. Due to the low operating position of the equipment, manual operation is difficult, requiring the removal of multiple parts, including the tail cover, and the use of specialized tools to complete the loading and unloading of the bomb. Summary of the Invention

[0003] The present invention addresses the aforementioned existing problems by developing a rapid loading and unloading mechanism and proposing an integrated tail cover for loading and unloading. This tail cover is modified from the original structure and includes additional components. This tail cover is integrated with the tail cover structure of the bomb delivery device, achieving multi-functionality and eliminating the need for specialized tools. This not only facilitates the use and maintenance of the device, improving its versatility and maintainability, but also reduces operational complexity, shortens loading and unloading preparation time, and effectively improves operational efficiency.

[0004] The integrated tail cover of the bullet ejection device is installed at the bullet inlet of the bullet tube, and includes: a tail cover and a projectile body locking and releasing mechanism integrated on the tail cover;

[0005] The projectile locking and releasing mechanism comprises: a bullet-extracting hook base and a bullet-extracting hook;

[0006] The loading and unloading hook comprises a straight section and a curved hook provided at one end of the straight section. The loading and unloading hook base is mounted on the tail cover. The straight section of the loading and unloading hook is rotatably connected to the loading and unloading hook base. The curved hook is used to hook the edge of the wing plate of the mine-killing bomb. The loading and unloading hook is rotated around the connection point between the loading and unloading hook base and the wing plate to achieve locking or releasing of the curved hook.

[0007] The mine-killing bomb is then loaded or unloaded after being locked by the bomb body locking and releasing mechanism.

[0008] As a preferred embodiment of the present invention, one loading and unloading hook base is installed on each opposite side of the tail cover, the straight sections of the two loading and unloading hooks are rotatably connected to the two loading and unloading hook bases respectively, and the curved hooks of the two loading and unloading hooks are used to hook the edges of the two wing plates of the mine-destroying bomb located in the horizontal plane.

[0009] As a preferred embodiment of the present invention, the bullet body locking and releasing mechanism further includes a connecting handle, which is fixedly connected to one end of the straight segments of the two loading and unloading hooks, and the loading and unloading hooks are rotated around the connection point with the loading and unloading hook bases by pressing the connecting handle.

[0010] As a preferred embodiment of the present invention, the projectile locking and releasing mechanism further comprises a handle, which is fixedly connected to the tail cover. When loading or unloading the projectile, the handle is lifted to place the mine-killing bomb locked on the tail cover into or out of the bomb tube.

[0011] As a preferred embodiment of the present invention, a positioning hole I is provided on the loading and unloading hook, and a through hole is provided on the loading and unloading hook base corresponding to the locking position. When the loading and unloading hook is in a locked state, the positioning hole I on the loading and unloading hook corresponds to the locking position through hole on the loading and unloading hook base. By inserting a positioning pin into the positioning hole I, the loading and unloading hook is limited so that it remains in the locked state.

[0012] As a preferred embodiment of the present invention, a positioning hole II is provided on the loading and unloading hook, and a positioning hole II is provided on the loading and unloading hook base corresponding to the release position. When the loading and unloading hook is in the released state, the positioning hole II on the loading and unloading hook corresponds to the release position through hole on the loading and unloading hook base. By inserting a positioning pin into the positioning hole II, the loading and unloading hook is limited to remain in the released state.

[0013] As a preferred embodiment of the present invention, the tail cover includes a cylindrical cover body with openings at both ends and four spoke-shaped legs evenly distributed along the circumference of the cover body. The ends of the four legs of the tail cover are respectively hinged to the bomb inlet at the tail of the grenade tube, and the tail cover is coaxially installed at the tail opening of the grenade tube. The end of the cover body facing the grenade tube is threadedly connected to the clamping seat, and the fuse of the mine-killing bomb is pressed onto the tail cover through the clamping seat. A threaded cover is provided on the upper end of the cover body of the tail cover and is threadedly connected to the threaded cover.

[0014] Beneficial effects:

[0015] (1) The present invention installs a bullet body locking and releasing mechanism on the basis of the original tail cover, which eliminates the need for special tools to load and unload bullets, thereby improving the efficiency of loading and unloading bullets and reducing the difficulty of operation.

[0016] (2) The loading and unloading hook can rotate around the loading and unloading hook base. By pressing the pull handle fixed at one end of the loading and unloading hook, the mine-killing bomb can be locked and released, which is easy to operate.

[0017] (3) A handle is provided on the locking and releasing mechanism of the projectile body. When the mine-killing bomb is locked, the handle can be pulled to load and unload the bomb, which is convenient for personnel to operate.

[0018] (4) Two positioning holes are provided on the loading and ejecting hook and the loading and ejecting hook base, which can keep the loading and ejecting hook stationary when the loading and ejecting hook is hooked or released. When the mine destroying bomb is hooked, the mine destroying bomb can be prevented from being separated from the loading and ejecting hook. When the mine destroying bomb is released, the loading and ejecting hook can be prevented from being stuck with the mine destroying bomb and unable to be released. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] This embodiment provides an integrated tail cover for loading and unloading missiles, in which the locking and releasing mechanism of the missile body is integrated into the tail cover. The loading and unloading tasks of the mine-dispelling missile can be completed when the tail cover is disassembled and assembled, which shortens the preparation time for loading and unloading missiles and effectively improves the working efficiency.

[0027] In this embodiment, four wing plates 11 are evenly arranged along the circumferential direction at the tail of the mine-extinguishing bomb 13 .

[0028] See attached Figure 3 In this embodiment, a plurality of parts are added to a traditional tail cover 1 to form an integrated tail cover. The integrated tail cover includes: a tail cover 1 and an elastic locking and releasing mechanism integrated on the tail cover 1;

[0029] See attached Figure 2The tail cover 1 includes a cylindrical cover body with openings at both ends and four spoke-shaped legs evenly distributed along the circumference of the cover body. The ends of the four legs of the tail cover 1 are respectively hinged to the bullet inlet at the tail of the grenade tube 14, thereby coaxially installing the tail cover 1 at the tail opening of the grenade tube 14; one end of the cover body facing the grenade tube 14 is threadedly connected to the clamping seat 2, and the fuse 12 of the mine-extinguishing bomb 13 is pressed on the tail cover 1 through the clamping seat 2, and the pull-out safety pin 6 of the mine-extinguishing bomb 13 is connected with the cotter pin 3 and the latch pin 4. The other end of the cover body of the tail cover 1 is threadedly connected to the threaded cover 5.

[0030] The bullet body locking and releasing mechanism includes: a handle 7, a connecting handle 8, a bullet ejection hook base 9, and a bullet ejection hook 10;

[0031] The loading and unloading hook 10 has a straight section and a curved hook provided at one end of the straight section;

[0032] The handle 7 is welded to two legs on the tail cover 1 that are located on the same straight line, which makes it convenient to take and put the tail cover 1; a loading and unloading hook base 9 is welded on each opposite side of the outer circumference of the cover body of the tail cover 1, and each loading and unloading hook base 9 is rotatably connected to a loading and unloading hook 10. Specifically: after the straight section of the loading and unloading hook 10 passes through the loading and unloading hook base 9, the middle part of the straight section of the loading and unloading hook is rotatably connected to the loading and unloading hook base 9 (such as pin connection), and the ends of the two loading and unloading hooks 10 extending out of the straight section of the tail cover 1 are fixed by the connecting handle 8 (such as by screw connection) as a whole.

[0033] In this example, the four wing plates 11 are distributed in a cross shape, and the two bullet-removing hooks 10 correspond to the two wing plates located in the horizontal plane respectively; Figure 3 The two hooks of the two ejector hooks 10 extend into the gap between the wing plates 11 and hook the edges of the two wing plates 11 respectively. The ends of the straight sections of the two ejector hooks 10 are connected by pressing and pulling the handle 8. The ejector hook base 9 provides a rotation fulcrum for the ejector hook 10. By pressing the pull handle 8, the ejector hook 10 can be rotated around the ejector hook base 9, so that the hook of the ejector hook 10 can hook or leave the edge of the wing plate 11, so as to achieve locking or release of the wing plate 11, that is, the mine-extinguishing bomb 13.

[0034] See attached Figure 4 and attached Figure 5, a positioning hole I15 and a positioning hole II16 are provided on the side of the ejector hook 10, and a through hole is provided on the ejector hook base 9 corresponding to the locking position and the release position. When the bottom end of the ejector hook 10 is bent into the gap of the wing plate 11 and hooks the edges of the two wing plates 11 located in the horizontal plane, the positioning hole I15 corresponds to the through hole in the locking position on the ejector hook base 9. A positioning pin can be inserted into the positioning hole I15 and the through hole at the corresponding position to limit the ejector hook 10 so that the ejector hook 10 cannot rotate, so that the integrated tail cover is kept in a hooked state. After the integrated tail cover hooks the mine destroyer bomb 13 and is loaded into the bomb tube 14, the axial movement of the mine destroyer bomb 13 along the bomb tube 14 can be restricted; after the positioning pin is pulled out, the pull handle is pressed. 8, the loading and unloading hook 10 can be rotated. When the loading and unloading hook 10 is rotated to a set angle so that the positioning hole II 16 corresponds to the through hole at the release position on the loading and unloading hook base 9, the positioning pin is inserted into the positioning hole II 16 and the through hole at the corresponding position to limit the loading and unloading hook 10 so that the loading and unloading hook 10 cannot rotate. At this time, the integrated tail cover remains in the released state. At this time, the curved hook of the loading and unloading hook 10 can be inserted into the gap of the wing plate 11 or the curved hook of the loading and unloading hook 10 can be removed from the gap of the wing plate 11 to release the fixation of the mine-extinguishing bomb 13. In this state, when the loading and unloading hook 10 is inserted into the gap of the wing plate 11, the tail end of the straight segment of the loading and unloading hook 10 just abuts the edge of the wing plate 11 perpendicular to the plane where the two straight segments of the loading and unloading hook 10 are located.

[0035] When it is necessary to load or unload the bomb, first hook the loading and unloading hook 10 of the integrated tail cover onto the mine-extinguishing bomb 13, insert the positioning pin into the positioning hole I15 and the through hole corresponding to the locking position on the loading and unloading hook base 9, keep the hook in a tight state, lift the handle 7 to load the mine-extinguishing bomb 13 into the bomb tube 14 or take the mine-extinguishing bomb 13 out of the bomb tube 14; when it is necessary to release the mine-extinguishing bomb 13, the mine-extinguishing bomb 13 has been loaded into the bomb tube 14, pull out the positioning pin in the positioning hole I15, press the connecting pull handle 8, insert the positioning pin into the positioning hole II16 and the through hole corresponding to the release position on the loading and unloading hook base 9, keep the integrated tail cover in the released state, release the limit on the mine-extinguishing bomb 13, and prepare for releasing the mine-extinguishing bomb 13.

[0036] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
