Description

The invention relates to packaging for storing ammunition and explosive charges and can be used for storage and transportation of ammunition of the Navy.

The main type of packaging for ammunition is currently a wooden box container. An insignificant part of tank shots requiring storage in sealed packaging are stacked in sealed metal cases.

More than half of the ammunition stockpiles in the arsenals and bases are stored in open areas under a canopy, which leads to wooden box containers that are damaged by fungi and reduce their service life. During the storage of ammunition, wooden box containers have to be repeatedly repaired or replaced with a new one. Storage of the shot in unusable containers shortens the period of its possible combat use. Arsenals and bases have to carry out a large amount of routine maintenance and repair work with ammunition and packaging.

At the same time, wooden box packaging is a combustible material and in all cases of fires, is the main source of development and spread of fire.

To date, the supply of the army for ammunition has no packaging with improved technical specifications for fire safety, durability, resistance to climatic and biological factors, and extended service life.

The issue of creating a new type of packaging that can extend the warranty period of storage of shots and ensure their safety throughout the storage and operation with minimal costs is relevant.

A well-known ammunition box containing bonded walls, a bottom and a lid made of fire-resistant composite basalt plastic (see RF patent No. 2285218 for 2005, IPC F42B 39/00).

The box has a classic shape for an ammunition box, but most importantly, the known design does not meet the complex of increased requirements for packing shots of the Navy.

Known case for a shot with an armor-piercing shell according to the patent of the Russian Federation No. 2372582 for 2008, IPC F42B 39/00. The known design cannot be operated in an aggressive environment.

The inclusion of the concept of “box” in the title of the invention is associated with the requirement of the customer included in the development contract to ensure stacking of the new design.

The authors were faced with the task of expanding the arsenal of technical equipment for this purpose and creating a design that fully meets modern requirements for the packaging of naval shots. This is remoteness by combining the capabilities of a box and a case.

The solution to this problem is ensured by the fact that the box-type box is characterized by the presence of a body made in the form of two pipes connected motionless by means of parallelepiped-shaped rims placed in the region of the pipe ends with stacking elements and handles of two kinds with the bottom being placed on one end of each pipe and at the second end of each lid pipe interacting through gaskets, including a protective one, and a removable extractor with a shot sleeve, which in turn interacts with a shell with a set of inset elements in and lock interacting with a rim and a lid, wherein the box elements other than the lock and individual pads are made of fiberglass, and ins elements - of polyurethane foam.

It is reliable if the rim is made of two symmetrical half-beads with a horizontal connector, forming two stepped cylindrical surfaces, covering the ends of the pipes, with steps of a smaller diameter and fastened to the pipes with an adhesive joint, and with each other bolts.

Conveniently, if the stacking elements are made in the form of protrusions and depressions on the halves of the rims, the depressions being made on the lower half of the rim and the protrusions on the upper.

It’s practical if the set of insert elements is made in the form of a first insert in the form of a thick-walled pipe installed at the bottom of the box, on the ends of which are reinforced with fiberglass ring with glue from the lid side, and plywood and protective gaskets from the bottom side, the second insert is also in the form of a pipe, inside of which it is flush with the end face interacting with the first insert, the liner is fixed with glue, the inner surface of which interacts with the projectile through the gasket, and at the end of the second insert from the side of the lid it is strengthened by gluing two half rings of a resilient material, cooperating with the flange shot sleeve.

It is necessary if a through hole of a rectangular shape is made on the side of the rim from the side of the cover to open the cover if it is stuck with a removed lock.

It is advisable if the handles are made in the form of tapes for transferring the box.

Effectively, if the protective pad is made in the form of one or two layers of glass cloth.

It is permissible if the lock includes a bridge, a lever fastened by an axis, made in the form of channels facing the shelves to each other, and the bridge is placed in the lever with an offset, and a fork for locking the lever from self-opening the lock, while at the open end of the bridge and at the end of the lever In the region of the axis, platforms for interaction with the rim are made.

Required if the lid of each drawer pipe is provided with a sleeve with a screw for checking the tightness of the pipe.

It is reliable if, in order to lock the lever from opening the lock in the shelves of the bridge, holes are made in which the ends of the rectangular loop are placed, and a slot is made in the lever to place the straight part of the rectangular loop in it.

Preferably, if the handles are made in the form of a rectangular bracket, one of the large sides of which is covered by a support mounted on the rim between the pipes and fastened to the rims by bolts fastening the half-rings.

The combination of features of an independent claim is not known to the applicant, which is proof of the novelty of the proposal, and each of these features clearly does not follow from the prior art, which is evidence of the existence of an inventive step in the proposal. Moreover, the authors emphasize the existence of a causal relationship between the essential features of the invention and the achieved technical effect.

The invention is illustrated by drawings, where figure 1 shows a sectional view of a box-type box. The figure 2 shows a view B of figure 1. Figure 3 shows a view A of figure 1. Figure 4 shows a view D of figure 3. Figure 5 shows two projections of the castle. In Fig.6 (for a better understanding of the design) in a perspective view shows a General view of the box case type in section. Also in a perspective view shows the cover - Fig.7, the bottom - Fig.8, the rim - Fig.9. An embodiment of the lock - figure 10 and handles - figure 11.

The box of a shaped type contains a housing 1 made in the form of two pipes connected motionlessly with the help of rims 2 in the form (see Figs. 3, 6, 9) of a parallelepiped of a pair of symmetrical half-rings connected horizontally to form two stepped cylindrical surfaces (see Fig. 9), covering the ends of the pipes with steps of a smaller diameter and fastened to the pipes with an adhesive connection, and with each other with bolts 3 (see Fig. 3). The rims are also made of fiberglass. Stacking elements are placed on the rims. On the lower half-circumference there are hollows 4, and on the upper half there are protrusions 5. On one side, the ends of the pipes are closed by a fiberglass bottom 6 installed on the adhesive with a protective gasket 7 glued to the bottom. The protective gasket is made of one or two layers of fabric glass grade E3-250-76. On the other hand, the pipes are closed with fiberglass caps 8, each of which is pressed to the end of the pipe through a rubber ring 9 with a metal lock 10, which makes the housing airtight. The cover is assembled on glue with a protective gasket 7, plywood circle 11, sponge rubber gasket 12 and cardboard circle 13. This design, interacting with the flange 14 of the sleeve of the unitary artillery shot 15, prevents its axial movement in the pipe using a set of plug-in elements in the form of pipes of different thickness, including the first insert 16 of greater thickness, resting on a plywood stop 17 glued to the protective strip 7. At the other end of the first insert, a fiberglass ring 18 is glued. On the second insert 19 (may be two parts) is mounted flush with the end facing the bottom of the body, inside the liner 20 with the gasket 21 on the 88-CA glue. At the end of the second insert, facing the cover, two fiberglass half-rings 22 are installed on the glue, preventing the destruction of solid polyurethane foam insert elements. The liner 20 with the gasket 21 with its inner surface repeats the shape and dimensions of the part of the head of the shell of an artillery shot. Inserted elements securely mount the shots and save them during operation. For the convenience of extracting a shot from the pipe, a removable extractor (not shown in the drawings) is used; it is made of a bundle of polyester sheet - a classic rope for arming yachts. As soft as possible and comfortable for working with hands. It is made on cordless machines. The core is braided polyester, the intermediate braid is textured polyester, the braid is polyester. Not affected by water and sun. The extractor is placed between the cardboard circle 13 and the bottom of the sleeve and the loop is thrown onto the sleeve flange (not shown in the drawing).

The lock 10 (see Figs. 5, 10) includes a bridge 23 and a lever 24, made in the form of channels facing the shelves to each other, the bridge is placed in the lever with an offset and both parts are fastened by the axis 25. To lock the lever from self-opening, there is a fork 26 (for reliability two). At the open end of the bridge and at the end of the lever in the region of the axis, platforms 27, 28 are made for interaction with the rim. In turn, grooves are made in the rim in the vertical plane, covered by metal jumpers 29, 30 (see Figs. 3, 9) to accommodate the open ends of the lever and bridge.

On the lateral sides of the rim from the side of the cover, through holes 31 of rectangular shape are made for opening the cover in case of sticking (see FIGS. 4, 9) with a removed lock.

To carry the box on both rims fixed handles in the corresponding holes of the handle 32 in the form of tapes (see figure 4). A sleeve 33 with a screw is mounted in the lid of each drawer pipe to check the tightness of the pipe. It is permissible if, to lock the lever from self-opening the lock in the shelves of the bridge (see Fig. 10), holes are made in which the ends of the rectangular loop 34 are placed, and a slot is made in the lever to place the straight part of the rectangular loop in it.

Preferably, if the handles 35 are made in the form of a rectangular bracket (see Fig. 11), one of the larger sides of which is covered by a support 36 mounted on the rim between the pipes (not shown in the drawings) and fastened to the rim by bolts 3 fastening the half-rings. The supports are a spatial structure, the sweep of which is cut out of the sheet and folded using a special device when installed on the rim.

Opening and closing the lock (in any embodiment), installing handles for carrying, as well as extracting shots and placing them in pipes, are very simple and do not cause difficulties for personnel.

The fiberglass pipe is made by the method of pultrusion, that is, the pipe is obtained by molding the necessary composition of a binder and glass roving or fabric. The speed of pulling through the die during the formation of a continuous pipe of 0.2-0.5 m per minute. One die is designed to produce 15 km of fiberglass pipe. The rim is made by pressing two halves. The mold is made for the simultaneous manufacture of two halves of the rim in one cycle.

The packaging is operated as a box, it is stacked to a height of 3.5 m, while the tightness control is carried out without dismantling the stack.

The box-type box has passed preliminary tests. It ensures the safety of shots, their free stacking, reliable fixation and removal in all operating conditions. It provides the possibility of stacking in the conditions of warehouse storage manually (by two people) and in a mechanized way. The box-type box is sealed, does not support combustion and ensures ammunition safety for six minutes when exposed to an external surface with a temperature of 550 degrees Celsius for 10 minutes. When heated, being in the fire focus does not emit harmful impurities in excess of the maximum permissible concentrations. After falling from a height of 1.5 meters on a steel plate ensures the safety of ammunition. Deformations resulting from the fall did not prevent the extraction of ammunition. There was no sticking the fuse into the wall of the package. The safety of ammunition is ensured even when dropped from a height of 10 meters. The case-type box maintains tightness when exposed to sea water at a depth of 20 cm for 24 hours, direct atmospheric precipitation at an intensity of 300 mm / h, and is not affected by molds. It maintains operational characteristics after exposure to electromagnetic fields and currents of electrostatic discharges, degassing, deactivating and disinfecting agents, does not ignite when shot through with an armor-piercing incendiary bullet of 12.7 mm caliber from a distance of 50 m.

The indicated advantages are ensured by the combination of materials used and design features and are superior to the standard capping (wooden box) currently used on Navy ships.

For the claimed technical solution, as described in the independent claim, the possibility of its implementation using the well-known tools and methods described in the application is confirmed. In turn, the claimed invention is able to ensure the achievement of the technical result perceived by the applicant, therefore, it meets the criterion of "industrial applicability" of the current patent law.
