Description

The invention relates to the packaging or storage of ammunition, and more particularly to the piece-laying of shells in containers for transportation in a fixed position.

The level of this technical field is characterized by the packaging for ammunition according to the patent RU 2149347, F42B 39/00, 2000, which contains a body with a hinged lid, equipped with cam-lever locks, tool holders with locking devices and rotary staples for carrying.

A shock absorber made of porous sheet rubber with a recess opposite the end face located in the munition package is mounted on the inner side of at least one side of the wall of the casing. The inlet section of the recess is smaller in size than the contacting end face of the ammunition.

Shock absorbers are installed on lodgements and fixing devices.

The locking device is made in the form of clamps mounted on rods located on the lodgements or on the bottom of the case, and drawn against the ammunition profile by nuts.

The lid with the body is made of wood and interconnected by hinges.

Along the perimeter of the package with relative displacement, transverse bars (stiffeners) are fixed, which serve as stops when stacking.

During transportation, vibration-shock loads acting on a package with ammunition laid in it are partially damped by shock absorbers.

In case of falling when stacking the package on the end from the sleeve side, the adjacent shock absorber partially dampens the shock load and, crushing, is not pressed due to the recess. This eliminates the possible deformation of the capsule and prevents its operation.

When the package falls to the opposite end, the movement of the ammunition is prevented by the cylindrical-conical shock absorbers of the tool tray and fixing device.

The disadvantage of the described design made of wood is its massiveness and fragility during reverse use.

In addition, when stacking the packages, they are not geometrically limited in transverse relative movement, which does not guarantee stability during transportation of multi-row stacks.

More perfect is a metal container according to patent RU 2114033, B65D 6/00, 1998, which is selected by the number of matching features as the closest analogue to the proposed one.

The known container is a metal container made by hinging a rigid body and a lid, which can be used for vertical stable stacking in rows when transporting goods dropped from aircraft to hard-to-reach areas, places of emergency situations and military operations.

The container contains a body, a bottom and a lid made of sheet metal and reinforced by transverse ribs, locking devices and tubular elements of the fixing unit mating when stacked, which are curved under the human hand.

The cam-lever locks and rotary staples for carrying are closed by tubular closed profiles protruding beyond the transverse dimensions of the body, fixed at the ends, which ensures their integrity during stacking and functionality during operation.

The bottom is made with bevels and equipped with runners that serve as a slope to overcome the unevenness of the supporting surface of the cargo compartments, performing auto-search for a stable position when the container turns.

The mating brackets of the horizontal sides of the closed tubular power profile of the ends mounted on each other containers, provides their geometric closure in the longitudinal direction.

The transverse supply (if necessary) of the container along the tubular support ensures the alignment of the protruding brackets, that is, fixing the lock connection in the transverse direction and the axial position of the containers in the stack.

The location of the upper horizontal sides of the power profiles of the end walls of the container body over its lid allows you to grab the product during loading and unloading manually and with gripping mechanisms without additional eyelets, which creates universality, simplifies the design and facilitates maintenance.

The absence of sharp corners in the mating surfaces and the use of smooth rounding of transitions and corner approaches in the mates and base elements ensured self-installation and reliable fixation of the containers in the stack with their rough preliminary orientation in space, which in turn facilitates rigging, minimizes their energy costs and labor costs to a minimum and significantly increases the efficiency of warehousing and loading of vehicles - important factors in emergency situations.

Operational manual transportation of containers for turning brackets or for brackets of the end tubular profile provides mobile delivery of goods to the place of consumption or loading into mobile vehicles.

The well-known container with a full payload of 110 kg ensures the integrity of the structure when dropped to the ground with a fall speed of up to 7 m / s.

However, a continuation of the advantages are inherent disadvantages, in particular the massiveness of the power elements.

In addition, the well-known container is not intended for laying and transporting piece goods in a fixed position, namely artillery shells with a toxic substance, for their safe delivery to the storage and disposal site.

The problem to which the present invention is directed, is to improve the metal container for universal use when laying shells of various calibers in an oriented position and transporting them in a fixed position.

In this case, the container should be reusable and maintain structural integrity when falling from a given height of rigging loading and unloading, and also ensure the safety of transportation of emergency shells and in official handling.

The required technical result is achieved in that in a known metal container containing a housing with a bottom, on which longitudinal skids are fixed, and a hinged lid reinforced from the inside, cam-lever locks, rotary staples for carrying, dimensional transverse stiffeners and fixing units when stacking, according to the invention, in the longitudinal runners located on the inside of the bottom, there is a measured number of mounting threaded holes for fastening rearranged lodgements carrying end stops under the length of the stacked shells, the fixing nodes when stacking have the form of pins on the lid, compatible with holes in the dimensional stiffening ribs of the bottom, while elastic elements are mounted on the lid reinforcements, and shutters are made in the body, while all the structural elements of the container are covered with a layer of heat-resistant paint.

Distinctive features made it possible to create a universal revolving metal container of a lightweight type and reliable when used for transporting large-caliber artillery shells in a fixed position.

The fastening of longitudinal runners from the inside of the bottom allows them to be used as a supporting structure for attaching lodgements for laying shells, thereby reducing the weight of the container.

The execution in the longitudinal runners of the measuring row of threaded holes is intended for rearrangement of tool holders, combined with end stops, when laying shells of various lengths, which expands the range of products stored and transported in a universal container.

Installation on the longitudinal runners of the lodgements provides oriented placement of shells in the mating profile, the longitudinal movement of which is physically limited by end stops, which are integral with the lodges.

The latter circumstance ensures the integrity of the container and the safety of the projectile in it when it falls from a height of 2 m onto a concrete slab, which is specified by the tactical and technical requirements and operating conditions.

The implementation of the locking unit when stacking in the form of pins of the cover, combined with holes in the overall ribs of the bottom stiffness is simple and functional. This design of the fixing unit provides a geometric closure of adjacent containers in the stack, eliminating any relative movements, and also reduces the total weight of the container.

The elastic elements mounted on the internal reinforcements of the cover serve for additional force fixing of the shells in the lodgement, thereby excluding their longitudinal movements within the backlash, distortions of the stacking.

Blinds of the body are used for temperature control of shells in stacks of closed containers installed in the production room before processing, which were stored in natural conditions under climatic differences in temperature of the territory. Disposal of shells with toxic substances is carried out at normal room temperature.

A layer of heat-resistant paint on the structural elements of the containers allows them to be thermally processed after use for transportation and storage of sealed shells in the territory of destruction of chemical munitions. After heat treatment at a temperature of 170-180 ° C, the containers are completely harmless and ready for subsequent use as intended.

Therefore, each essential feature is necessary, and their combination is sufficient to achieve a novelty of quality that is not inherent in the signs of disunity, that is, the technical task posed is not solved by the sum of the effects, but by a new effect of the sum of the attributes.

A comparative analysis of the proposed technical solution with identified analogues of the prior art, from which the invention does not explicitly follow for an ammunition specialist, showed that it is not known, and given the possibility of industrial serial production of universal metal containers, it can be concluded that the patentability criteria are met.

The invention is illustrated by drawings, which depict:

figure 1 - the proposed container in the closed position;

figure 2 is the same with the lid open.

The proposed container includes a body 1 welded together with a bottom 2 (figure 2) and a cover 3 pivotally connected to the body 1, made of sheet metal.

Transverse channels 4 (stiffeners) are fixed along the perimeter of the bottom 2 and the housing 1, and the reinforcements 5 of the cover 3 in the form of a lattice of channels are made from the inside (Fig. 2).

Inside the housing 1, along the bottom 2, runners 6 are fixed, in which there is a measured row of threaded holes 7 for bolting the lodgements 8, 9, having a mating profile with the corresponding part of the stacked projectile (not shown conditionally).

The lodges 8 and 9 are seamlessly connected with the end stops 10, 11, respectively, located along the length of the stacked projectile.

The drawing shows a variant of the two-position lodgment 8, 9 for laying two of the same type of shells. Depending on the caliber and length of the shells, various arrangements are possible, in particular, for one shell or for four, when two additional tool holders 8, 9 with end stops 10, 11 are mounted on the runners 6.

Blinds 12 are made in the housing 1, and pivoting brackets 13 are mounted at the ends for carrying the container.

On the reinforcements 5 (channels) of the cover 3, elastic elements 14 made of rubber are mounted under the outer profile of the stacked projectile, and pins 15 are fixed on the outside of the cover 3 (Fig. 1), which are combined when stacking containers with basing holes 16 in the corresponding channels 4 of the bottom 2.

The housing 1 with the cover 3 in the closed position is fixed by cam-lever locks 17.

All structural elements of the container are coated with heat-resistant paint brand KO-868 "Certa", which is functionally reliable with prolonged exposure to a temperature of 600 ° C.

Use the proposed universal metal container as follows.

Shells with toxic substances are laid on lodges 8, 9, pre-mounted on the longitudinal runners 6 of the bottom 2, securing them with bolts in the necessary threaded holes 7 so that the distance between the end stops 10 and 11 corresponds to the length of the projectile.

After this, by turning the lid 3 until it closes with the housing 1, the container is closed, compressing the elastic elements 14, which are based on the profile of the projectile.

Then the cam-lever locks 17 carry out geometric and power closure, providing additional clamping of the cover 3 and the elastic deformation of the elements 14. The container with a sealed shell is ready for transportation.

To carry the packed containers, rotary brackets 13 are used.

When stacking containers with holes 16 in the ribs 4 of the rigidity of the bottom 2 are oriented to the pins 15 of the cover 3 of the underlying container. In this case, their geometric closure occurs, and the ribs 4 of the bottom 2 of the upper container are tightly mounted on the cover 3 of the lower container, thereby ensuring a stable position of the stacks, in which it is allowed to install six containers.

When forming adjacent rows of stacks of containers, the transverse ribs 4 of the stiffness of the housing 1 protect them from impacts and, accordingly, wrinkles, their locks 17 and brackets 13.

Containers with packed shells are stored in unheated rooms at ambient temperature, so before disposal they are placed in a production room with a normal temperature, where the temperature is equalized due to the thermal conductivity of the metal container, reinforced by convective heat transfer through the louvres 12 of the building 1.

After a given exposure in the production room, the containers are opened in the reverse order of operations and the shells that are fed for processing are removed.

Free containers are then subjected to heat treatment in a chamber with a temperature of 180 ° C for the time stipulated by the Regulations for the sanitary-prophylactic treatment of products that have passed the storage and destruction zone of chemical munitions.

Heat-treated containers are ready for reuse.

An experimental verification of the proposed design of the universal container and its disinfection allows us to recommend it for departmental testing for industrial use under the program for the destruction of chemical weapons.
