Description

The invention relates to military equipment, to technology for protecting explosive cargo, to packaging intended for the safe transportation and storage of ammunition, and specifically concerns cases for individual mortar rounds or mortar mines that ensure safety during transportation and storage.

Currently, there are no known analogues of universal packaging for storing individual mortar rounds and mortar mines, as well as complete rounds in the form of a mortar mine with a propellant charge for mortars.

Until now, mortar rounds and mortar shells were placed and stored separately in wooden boxes. The boxes contain unique cradle for a specific shot or mine. A wide range of mortar rounds is a set of different mortar shells, united by a single caliber, having different geometric dimensions in length and shape. This circumstance does not allow the use of a single cradle of fixed geometric dimensions to accommodate a mortar round when carrying (transporting) and storing shots and mines of the same caliber.

The disadvantage of using wooden boxes for placing and storing mortar mines is:

- a large range of boxes and trays in them;

- large dimensions and weight of the boxes due to the irrational use of the volume of boxes of the same size when placing mines of the same caliber, but of different lengths;

- placement of several shots or shots with a mortar mine in one box;

- unsafe storage due to the use of wood, which is susceptible to burning and rotting;

- massiveness and fragility during reverse use.

The level of this field of technology is characterized by a metal container for projectiles according to patent RU 2363926 C1, MPK 42V 39/22, 2009, containing a body with a bottom on which longitudinal runners are fixed, a hinged lid with reinforcements from the inside, cam-lever locks, rotary brackets for carriers, dimensional transverse stiffening ribs and fixation units for stacking, rearrangeable cradles that carry end stops for stacked projectiles, longitudinal skids are located on the inside of the bottom and have a number of mounting threaded holes in them for attaching repositionable cradles. The fixation units for stacking have the form of pins on the lid, aligned with holes in the overall transverse stiffening ribs of the bottom, while elastic elements are mounted on the lid reinforcements, and blinds are made in the body, while all its structural elements are covered with a layer of heat-resistant paint.

The disadvantage of using this is that only identical projectiles can be placed in this metal container and under them it is necessary to install rearrangeable cradles made in the form of a partition by unscrewing and tightening the fastening elements in longitudinal runners with a measured row of threaded holes, while the longitudinal movement of the cradles is physically limited end stops, monolithically connected to the cradle. Projectiles of different lengths cannot be mounted on supports in one metal container, that is, the scope of use of this container is very narrow. For projectiles of different shapes, it is necessary to install a specialized cradle, which must be stored somewhere.

Repositionable supports in the form of a partition are installed in the body of a metal container. Additional forceful fixation of projectiles in the cradle is provided only by individual segmental elastic elements on the lid of the metal container.

Another disadvantage is the need to store and transport shells placed in a metal container in a position where the lid is located only on top. The container lid is a membrane that can bend when exposed to projectiles when the metal container is turned over, and the projectile begins to move in the cradle.

To correctly orient the position of metal containers when stacking, containers with holes in the bottom stiffeners are oriented to the pins of the lid of the container below, thereby ensuring a stable position of the stacks.

Also known is a case for firing an armor-piercing projectile, containing an outer shell, an inner package with a unit for its fixation in the outer shell and with a device for fixing the projectile, covers forming with the inner package a cavity for placing the shot, at least one lock, handles for carrying the case on the covers, is additionally equipped with two reinforcing cylinders with rims placed at the ends of the case on the outer surface of the outer shell, and on each rim there is a square frame with elements for fixing the case when it is installed in a stack, while the cavity for placing the shot includes a cavity for placing the main charge in a sleeve with a flange shot of separate-case loading with its internal packaging and extractor and a cavity communicating with it for placing a projectile with an additional charge with its internal packaging, brackets with hooks are installed on the covers in the spaces formed by the corners of the square frames and parts of the cylindrical surface of the rims for lock grips for autonomous adjustment of the tension of the lids, the locks are made of a tension type with a grip in the form of a plate with a hole for the bracket hook and are installed on reinforcing cylinders with a rim; transverse recesses are made on the outer shell for fixing internal packages. For autonomous adjustment of the tension of the covers, it is equipped with a gasket that interacts with the cover and rests on a rubber buffer in the cavity to accommodate the projectile with an additional charge and a gasket and a rubber buffer placed between the gasket and the cover in the cavity to accommodate the main charge (see patent RU 2372582 C1, MPK F42B 39/00, 2009) is the closest analogue (prototype).

As an analysis of the design of the case has shown, in its case it is possible to install only one shot with an armor-piercing projectile of one caliber, that is, the design of the case does not contain elements for its conversion to install ammunition of other sizes. In addition, elastic fixation of ammunition in the case body with a rubber buffer cannot ensure a stable position of ammunition when transported in off-road conditions or when transporting projectiles and ammunition in any spatial position.

The objective of the present invention is to expand the operational capabilities of the case by creating a case design that allows, with minor adjustments, to use it for storing and transporting ammunition of various sizes and properties, including ammunition, mortar mines or complete mortar rounds in the form of a mortar mine with a fuse, main and additional propellant charges, of various types and purposes (fragmentation, illumination, incendiary, propaganda, smoking, etc.) of the same caliber when stored and carried (transported), providing protection, reliable fixation inside the case and preventing external influences.

The technical result of the proposed technical solution is the creation of a rigid universal case of a certain length for storing, carrying, transporting (shipping) shells, mortar mines and completed mortar rounds of the same caliber, in which charges, mortar mines of different shapes and lengths can be placed, using different layouts for their placement and fastening, increasing the protection of ammunition equipped with a fuse from external influences of damaging elements, increasing protection by weakening the fragmentation field affecting mines in a universal case from external influencing factors, an emergency explosion and preventing abnormal penetration of ammunition, a mortar round with the ability to determine the nomenclature packed ammunition in a universal case.

The technical result is achieved by the fact that the universal case has more than one place for placing shells, mortar rounds or mines, consists of a cylindrical case body, a movable carriage that can be fixed inside in the middle part of the case, two end covers with movable bushings and spring clips. There is no separate internal packaging for shells, mortar rounds or mines. The case body has a cylindrical shape, the internal diameter of which is greater than the diameter of the mine with a guaranteed gap to ensure free movement of the mine in the case body. The design of the case body can be either solid or consisting of several components assembled mechanically (threaded connection) or welding and is determined by the technological capabilities of the manufacturer and the choice of initial blanks, or can be made monolithic from non-metallic materials. Depending on the length of the case body parts, you can assemble a universal case of different lengths and expand the range of ammunition to be placed in the case.

The carriage consists of a carriage body with polymer bushings at the ends and is an element that regulates the position of a mortar mine or shot in the body of a universal case, to ensure its reliable fixation, eliminating axial movements relative to the case body.

To carry (transport) and store mortar shells or rounds from a product (for example, an 82 mm caliber mortar), the carriage is secured in the middle position inside the case. Fixation of the position of mines and shots is ensured by the presence in the carriage body of polymer bushings with supporting surfaces for the ogival part of the mortar mine. Fixation of the carriage body is ensured by axial position clamps that fit into segment grooves located in the central part of the case.

To install the carriage into the case, segmented openings are provided on both sides of the case to allow insertion of the carriage. The clamps are turned off when the carriage is inserted into the case by turning the carriage to an angle (approximately 45°) necessary to compress the springs under the axial movement clamps. The latches are turned off in the same way in the middle position of the carriage in the case; only to turn the carriage, the key included in the set of spare parts, tools and accessories supplied with the product (mortar, or other weapons) is used. Adjusting the position of the carriage in the case body to ensure placement of mortar shells of different lengths in the universal case is carried out by setting fixed positions of the adjusting sleeve and blocking the possibility of its movement relative to the carriage body with the size regulator lock.

To ensure fixed positions of various mortar shells or rounds in a universal case, the cylindrical part of the adjusting sleeve is provided with adjustable grooves of different lengths, in which the size regulator lock can move, and which determine the length of the carriage. The adjusting grooves have movement blocking grooves for the conical surface of the size adjuster clamp and ensuring fixation of the adjusting sleeve in the carriage body for the type of shot or mine being placed, depending on its length. The number of slots is determined by the range of shots being transported or stored.

Before placing a mortar shell or a shot into a universal case, it is configured. The adjustment is carried out by aligning the adjusting sleeve relative to the carriage body, for which it is unscrewed with the size regulator lock, the adjusting sleeve is set to the required size by aligning the groove corresponding to the loaded mortar mine or shot, with the fixation in the corresponding counterbore blocking the movement of the size adjuster lock. Depending on the type of ammunition being loaded, the carriage is installed in the body of the universal case, either with its middle position in the case body, or with an emphasis on the end cover installed on one side. Once a mortar round is loaded or a shot is fired, the second end cap is closed.

To ensure the stationary position of the ammunition inside the universal case and to prevent it from moving during transportation, it is pressed and secured with a clamping sleeve in the end cover. If necessary, the clamping sleeve is pressed in the same way in the cover on the opposite side of the body of the universal case.

To determine the range of ammunition packed in a universal case, the body of the universal case is equipped with a rigidly fixed nameplate depicting a list of types of ammunition, equipped with movable indicators having holes on the front surface, which, when rearranged along the nameplate in the index window, indicate the type of ammunition packed in the universal case.

Once the ammunition is placed in the universal case and indicators are installed to indicate the type of ammunition, it is ready for transport. When transporting, universal cases can be inserted into cassette containers or placed on a flat surface. For positioning in the cassette container and preventing rotation of the universal case when it is on a flat surface, the case body has at least three elements that prevent free rotation when the universal case is on a flat surface and positioning the universal case.

In addition, the technical solution is aimed at:

- reducing the weight of containers for storage, carrying and transportation;

- reducing the volume occupied by a universal case when carrying and transporting ammunition and mines;

- increasing safety when storing ammunition by preventing uncontrolled movement of the universal case.

What is new is that:

- the universal case is made of a certain length, and to accommodate a larger shot or several shots, the internal volume of the case is changed while maintaining the external dimensions;

- it becomes possible to place in a universal case mortar mines or complete mortar rounds in the form of a mortar mine with a fuse, main and additional propellant charges, of various types and purposes (fragmentation, illumination, incendiary, propaganda, smoking and others) of the same caliber;

- expansion of operational capabilities is ensured due to the fact that it contains elements and means of fixing specific types of mortar rounds and mines, which are transformed depending on the shape and size of mortar rounds and mines;

- in the inventive universal case, the possibility of reliable fastening of mortar rounds and mines of the same caliber is realized simultaneously on the side surface and ends, as well as due to adjustable elements in the carriage and in the end caps in contact with parts of the ammunition, with fixation elements in the closed position;

- the body of a universal case can be either solid or consisting of several components assembled mechanically (threaded connection) or by welding and is determined by the technological capabilities of the manufacturer and the choice of initial blanks, which makes it possible to assemble cases of different lengths and expand the range of ammunition for placement in the case;

- the possibilities for ensuring the safety of transportation and storage in various spatial positions of the universal case have been expanded by preventing uncontrolled movement of the universal case;

- the presence of nameplates indicating the type of ammunition stored allows for faster use of ammunition;

- the presence of two end caps speeds up the process of removing ammunition and mortar rounds from the universal case.

The inventive universal case for mortar rounds or mines is illustrated by the drawings shown in Fig. 1, 2, 3, 4. In the drawing, FIG. 5, fig. 6 shows possible schemes for laying and securing mines in a universal case for storing and transporting mortar rounds or mines. In the drawing FIG.

A universal case for mortar rounds or mines consists of a case body 1 (Fig. 1), a movable carriage 2, which can be fixed in the middle of the case body 1, two end covers 3 with movable bushings and spring clips. The case body 1 is made of metal, has a cylindrical shape, the internal diameter of which is greater than the diameter of the mine with a guaranteed gap to ensure free movement of the mine in the case body 1. The outer surface of the case body 1 has at least three protruding bands 15. At the location of the protruding bands 15 on the inner of the surface of the case body 1 in the central part, in a plane perpendicular to the axis of the case body 1, there are four segmental grooves 16 for the latches 11 of the carriage 2, and at the end sections there are continuous annular grooves 5 for the spring retainer 6.

To install the carriage 2 into the case body 1, segmental recesses 17 are provided on both sides of the case body 1, ensuring the insertion of the carriage 2.

The design of the case body 1 can be either solid or consisting of several parts of different lengths, assembled mechanically (threaded connection) or by welding and is determined by the technological capabilities of the manufacturer and the choice of initial blanks.

End cap 3 (Fig. 2), which is inserted into the case body 1, consists of two mechanically assembled elements: end cap 3 and movable clamping sleeve 4. In the center of end cap 3 there is a key 7, with a slot for a slotted screwdriver, for rotation and movement along the external thread of the clamping sleeve 4 relative to the end cover 3, including a stroke limiter that eliminates the possibility of disconnecting them from each other. On the end surface of the end cover 3 there is a fixedly fixed annular support gasket 26 made of soft non-metallic material for contact with the end parts of the ammunition and min.

Between the clamping sleeve 4 and the end cap 3, along the axis of the key 7, there is a spring 18 to prevent self-unscrewing of the clamping sleeve 4 from the end cap 3. In the recess on the outside of the end cap 3, using a shaped clamp 19 fixed with screws 20, a spring clamp 6 formed from a piece of wire having in the middle part at least a quarter of a turn coupled with two movable arms in the form of lateral bends in the plane of the turn and handles at the ends perpendicular to the curly bends. The spring clamp 6 blocks the possibility of axial movement of the end cover 3 when the bends of the arms fall into the grooves 5 on the inner surface of the case body 1.

Carriage 2 (Fig. 3) consists of: a carriage body 8 in the form of a hollow metal cylinder with symmetrically located grooves on the outer surface, a control bushing 13 in the form of a metal hollow cylinder with longitudinal control grooves 27, 28, 29, 30 (see Fig. 4) of different lengths and with a flange at one end, inserted for movement into the carriage body 8, two polymer bushings 9, fixed at the end of the carriage body 8 with screws 21 and on the flange of the adjusting bushing 13 with screws 22 with a nut 23. The diameter of the outer surface of the carriage body 8 and polymer bushings 9 corresponds to the caliber of ammunition or mine.

The polymer bushings 9 are made in the form of a hollow cylinder, have an internal conical supporting surface 10 for contact with the ogive part of the mortar mine at one end and a flat end with holes for fastening screws 21 and 22 at the other end. The diameter of the inner surface of the polymer sleeve 9 is greater than the diameter of the fuse installed in the mine or ammunition.

On the outer surface of the carriage body 8 in the middle part and in the same plane there are two axial position clamps 11. The axial position clamps 11 are cylindrical in shape, spring-loaded by a spring 24, secured with a screw 25 in a socket on the carriage body 8. When the spring 24 is compressed, the axial position clamps 11 do not protrude beyond the outer surface of the carriage body 8.

On the flange side of the adjusting sleeve 13 (see Fig. 4), on the carriage body 8 there is a size 12 adjuster retainer in the form of a pin with a threaded surface. In the carriage body 8 there is a threaded hole into which the threaded part of the adjuster locking pin of size 12 is screwed. The surface of the pin moves in the regulating grooves 27, 28, 29, 30 on the cylindrical part of the regulating sleeve 13. In the end part of the regulating grooves 27, 28, 29, 30 a movement blocking 14 is counterbored for the conical surface of the size 12 regulator lock, into which it is screwed.

The different lengths of the adjusting grooves 27, 28, 29, 30 on the cylindrical part of the adjusting sleeve 13 determine the overall size of the carriage 2 when rearranging the adjuster lock of size 12.

When using a universal case, before placing a mortar mine or a mortar round in the universal case, it is configured.

The adjustment is carried out by changing the length of the carriage 2. First, one end cover 3 is removed, for which it is necessary to compress the handles of the spring clamp 6, remove its side bends from the groove 5 and remove the end cover 3 from the case body 1.

Then remove the carriage 2 from the case body 1. On the carriage body 8, the adjuster lock of size 12 is unscrewed from the movement blocking counterbore 14. The adjusting sleeve 13 is set to the required size, relative to the carriage body 8, by aligning the groove 27, 28, 29, 30 corresponding to the standard size loaded mortar mine or shot, with fixation in the corresponding counterbore of the movement lock 14 of the size 12 adjuster clamp. Fixation of the position of the mines and shots is ensured by the presence in the carriage body of 8 polymer bushings 9 with supporting surfaces for the ogival part of the mortar mine 10.

For carrying (transportation) and storage of mortar shells or rounds in a universal case, the carriage 2 is secured in the middle position of the case body 1. The carriage body 8 is secured by the axial position clamps 11, which fit into the segment grooves located in the central part of the case body 1. For installation carriage 2 into the body of case 1, on both sides of the body of case 1, segmental recesses are provided to ensure the insertion of carriage 2. Disabling the latches 11, when inserting carriage 2 into the body of case 1, is carried out by turning the carriage to the angle (approximately 45°) necessary to compress the springs under the latches axial movement 11. The latches 11 are turned off in the same way and in the middle position of the carriage 2 in the case body 1, only to turn the carriage 2 the key included in the set of spare parts, tools and accessories supplied with the weapon or mortar is used.

Depending on the size of the loaded mines or mortar rounds, the carriage 2 is installed in the case body 1, either with its middle position in the case body 1, or with an emphasis on the end cover 3 installed on one side.

After loading a mortar mine or firing a shot into the case body 1, the second end cover 3 is closed, for which it is inserted into the open end of the case body 1, the handles of the spring clamp 6 are compressed, and its side bends are inserted into the groove 5 on the inner surface of the case body 1.

To ensure a stationary position of the ammunition inside the case body 1, the end cover 3 is inserted, the ammunition is pressed with a clamping sleeve 4 with a support gasket 26 on the inside of the end cover 3 due to its rotation using a key 7. If necessary, the compression is also carried out on the opposite side of the case body 1 , similarly, by rotating the clamping sleeve 4 using the key 7 in the end cover 3.

Examples of options for laying mortar rounds or mines are shown in the drawings of Figs. 5, 6. Two identical mines 31 or mines 32, 33, 34, but of different lengths and warhead sizes, can be placed in a universal case.

To determine the range of ammunition packed in a universal case, the body of the universal case 1 is equipped with a rigidly fixed nameplate 35 (see Fig. 7) depicting a list of types of ammunition, equipped with movable indicators 36 having holes on the front surface, which, when rearranged along the nameplate 35, in the indicator window 36 indicate the type of ammunition stored in the universal case.

Once the ammunition is placed in the universal case and the indicators 36 are installed to indicate the type of ammunition, it is ready for transportation.

During transportation, universal cases can be inserted into cassette containers (not shown in the drawings) or laid on a flat surface.

For positioning in the cassette container and preventing rotation of the universal case when it is on a flat surface, the case body in the middle part on the protruding belt 15 has elements in the form of corner ribs 37 that prevent free rotation when the universal case is on a flat surface and facilitate the positioning of the universal case in the cassette container during transportation.

To carry the universal case, a belt is used (not shown in the drawings) with self-tightening loops at the ends. The loops are thrown onto the universal case and, when positioned between the protruding belts 15, are tightened.

The inventive universal case for storing and transporting ammunition, mortar rounds or mines provides expanded operational capabilities due to the fact that it contains elements and means for fixing specific types of mortar rounds or mines, which are transformed depending on the shape and size of the mortar rounds or mines.

As a result of the use of the entire set of features in the inventive universal case, the possibility of safely transporting a wide range of mortar rounds or mines of the same caliber is realized due to adjustable elements in the carriage and end caps, and the possibilities for ensuring the safety of transportation and storage in various spatial positions of the universal case are expanded.

We believe that the information contained in the application materials is sufficient for the practical implementation of the invention when developing an 82-mm self-propelled (carryable) mortar.
