Description

The invention relates to containers for storage and transportation of products, and more particularly to ammunition containers made in the form of pallets with side composite walls.

The level of this technical field is characterized by a universal multi-turn collapsible box described in patent RU 2113107, A01F 25/14, 1998, containing a bottom with supporting protrusions of the type of bars and four walls connected by quick disconnect joints.

The disadvantage of the described container is that all solid walls are load-bearing and attached to the bottom, which complicates assembly-disassembly and increases the ballast mass of the container due to the high material consumption, which increases consumer cost and complicates the technology in official handling when packaging products, cargo for storage and transportation, disassembly and stacking when folded for delivery to the consumer.

The noted disadvantages are eliminated in a more advanced multi-turn collapsible container according to the patent RU 2198494, A01F 25/14, B65D 6/24, 2003, which is selected by the number of matching features as the closest analogue to the proposed one.

The known container contains a bottom with support bars and interconnected lattice walls fastened with transverse ties.

Two opposite walls rest on the bottom and are load-bearing; two other walls are suspended on them.

The container has stacking latches made in the form of corners fixed on the upper couplers, the shelves of which are facing outwards.

The advantage of the known container is that for its assembly and disassembly does not require a special tool.

The quick disconnect connection is made in the form of a bracket rigidly connected to the lower end of the extreme struts of the bearing wall and covering the ends of the extreme beam of the bottom, with at least one, the lowest horizontal screed of the bearing wall made of two halves horizontally, and the racks connected to the inner ends of these halves are installed with an inclination in at least one of the sections in height and are covered by a movable clamp on them, tightening these racks in one of their extreme positions.

However, the advantages described above continue with their inherent disadvantages, in particular, the container does not have a lid forming it as an autonomous, mobile transported unit; therefore, it is impossible to overload the known container with a direct hook from above, since the walls are not vertically bonded to each other and to the bottom, but are connected by a geometric closure , which limits the technological capabilities of rigging, complicates the process of loading containers into the holds of boats, in railway cars, etc. .

In addition, the screed of inclined racks by means of a movable clamp is, by definition, unreliable during transportation, when under the influence of vibrations and shaking, the clamp will automatically move upward along the inclined surface of the racks, weakening the force of their pulling together. In the extreme upper position of the clamp, the pulling force completely disappears, freeing the walls, as provided by the technology of forced disassembly.

That is, the container unauthorized loses its structural rigidity and bearing capacity as a transport container, without additional means of fixing the clamps, which in principle is not intended to be used in the working position, which limits the scope of application only for warehousing of products and goods.

The design of the container does not provide means for fixing the relative position of containers during stacking, which is unacceptable by the norms and requirements of official handling of ammunition sealed in containers.

The problem to which the present invention is directed, is to improve the well-known collapsible multi-turn container by eliminating the noted drawbacks to increase functional reliability and expand the scope.

The required technical result is achieved by the fact that the well-known multi-turn collapsible metal container containing a bottom with supporting bars and interconnected quick-disconnect lattice walls with rigid transverse ties, two of which are supported on the bottom and two other walls are suspended on them, according to the invention equipped with a lattice cover with couplers in which the mounting holes are made, the bottom is placed in a box-shaped base, at the ends of which are fixed two threaded the pin, and the side walls are made resting on the bottom, while the end walls are made with through grooves for the said pins and are provided with bearing corners to cover the base from below and the side walls from above, with transverse ties made in the form of inclined visors fixed above the said through grooves, rigging eyes secured vertically and threaded pins for the mounting holes of the cover couplers, and all threaded pins are kinematically closed by means of a power connection with nuts, to the coupler covers protrusions and on the supporting bars - grooves for engagement with said projections of another container when stacked.

Distinctive features told the container a new quality: functional reliability in official circulation as intended due to the geometric and power closure of the docked forming elements in a rigid structure, a mobile and autonomous transport unit suitable for all types of loading and rigging.

Placing a metal bottom in a box-shaped base forms a bearing support of predetermined geometric dimensions intended for installation, storage and transportation of a multi-row set of sealed metal containers with packed artillery shells

The metal bottom is placed in a box-shaped base for forming dimensional limiters for installing walls in the longitudinal gaps between pre-installed rows of boxes with packaged products, which creates a monoblock container and allows you to organize the technological sequence of its assembly.

The fastening on the end sides of the base with two threaded pins under the through grooves of the end walls serves to automatically orient when assembling adjacent structural elements for their power connection in a spatial form.

Equipping the box-shaped base on the end sides with two threaded pins provides a rigid connection with the adjacent end walls, forming a U-shaped assembly semi-finished product, connected by power nuts, when combined with a geometrically closed container configuration formed with the side walls installed on the bottom of the base. This is due to the coverage of load-bearing corners fixed to the end walls: the box-shaped base from the bottom and the side walls from the top.

Equipping the end walls with load-bearing corners to cover the base from the bottom and the side walls from above is intended to create a power closed structure with a uniformly distributed load of the transported cargo mass.

The support of the side walls on the metal bottom provides the load-bearing properties of the formed container, in which the side walls serve as power bridges between the base and the roof, perceiving distributed vertical loads.

Fastening on the end walls with two lifting eyes provides an additional opportunity for loading the container with hoisting machines and mechanisms using guides and supporting ropes, chains with a hook on top.

The fastening on each end wall of the top two threaded pins is designed to base the mounting holes of the lattice cover ties, providing the formation of a load-bearing container closed around the perimeter, suitable, in addition to reloading and unloading with a forklift with a fork under the bottom of the base, and for hanging when using cranes, winches, etc.

The forming elements of the container form a tight connection during operation in official circulation for the intended purpose with wider functional capabilities both for transportation and for non-load-bearing overloads.

The execution of the lattice lid is, by definition, a lightweight power structure that ensures reliable operation at a given mechanical load.

The lattice lid is a kind of pantograph, in which alternating loads are compensated, and working mainly on compression, causing not only horizontal but also vertical reactions (spacers) in the supports, perceived by the base pins.

The installation on the screeds of the trellised cover of the protrusions, combined with the grooves of the support bars, ensures the fixation of the upstream container when stacking.

The execution of transverse couplers of the end walls fixed above the quick-disconnect joints in the form of inclined visors protects the latter from mechanical stress during loading and unloading operations with other massive containers, while preventing deformation of the quick-connect joints that could make it difficult or even impossible to disassemble.

Making quick-disconnect connections in the form of a screw pair, a stationary fixed threaded rod - a power clamp nut is the simplest, universal device for a movable connection. This quick-disconnect connection is used for automatic orientation and basing of compatible structural structural elements by mounting holes on the pins in the required mutual position, which ensures their geometric closure, which is fixed by a rigid force clamp by means of a nut.

The configuration and geometric dimensions of the structural elements provide, in a disassembled form, their compatibility in tight packaging, the volume of which is four times less than the volume of the container, which ensures the expediency of returning containers for multi-use.

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

The invention is illustrated in the drawing, which shows:

figure 1 - General view of the container assembly;

figure 2 is a view along arrow A on the end wall;

figure 3 is a view along arrow B, a top view;

The proposed container, which is a structural unity in official circulation, is intended for transportation of small-caliber shells packed in sealed metal containers according to patents RU 30967, 45182, 46348, 57884 and is characterized by the possibility of quick assembly-disassembly for repeated use as a means of transporting products.

Boxes with shells stacked in rows are mounted on a metal bottom 1, placed in a box-shaped base 2, which is supported by bars 3 (Fig. 1, items 4 and 5). On the end sides of the box-shaped base 2, two threaded pins 4 are welded under the fastening nuts 5.

The container is assembled in the following order.

Two lateral lattice walls 6 are placed on opposite sides 1, adjacent to the outside to the rows of boxes with shells, filling in the technological gap provided for this.

The side walls 6 are made in the form of a welded supporting frame with three transverse ties 7.

The lattice end walls 8 (FIG. 2) of the frame structure are equipped with a horizontal screed 9 fixed above the landing grooves 10 under the base pins 4 of the base 2 and made in the form of an inclined visor (FIG. 1).

At the top of the end walls 8, two lifting eyes 11 are welded and two threaded rods 4 longitudinally on the upper coupler 9.

On the inner side of the walls 8, dimensional corners 12 are welded.

The end walls 8, being guided by the landing grooves 10 on the pins 4 of the box-shaped base 2, are installed at the ends of the side walls 6 so that the upper corner 12 covers the walls 6 from the top, and the lower corner 12 - the base 2 from the bottom, forming an open box. This position is fixed by nuts 5, screwed onto the pins 4 of the base 2.

Next, a lattice cover 13 is mounted on the pins 4 of the end walls 8, the longitudinal ties 14 of which are fitted with the mounting holes on the threaded pins 4 of the end walls 8, rigidly linking the assembled container into the monoblock by means of nuts 5.

On top of the lid 13, protrusions 15 are fixed on its ties 14 for fixing in the grooves 16 (Fig. 2) of the support bars 3 of the upstream container when stacking.

After the assembly of the container with the installed rows of metal containers carrying the packed shells, all the nuts 5 are sequentially screwed on the threaded pins 4 until they stop, choosing the gaps and backlash in the assembly and joints.

Stacking is limited by the technical conditions of the installation of four containers.

When reloading containers with cargo by forklifts, its load-bearing forks are located under the base 2 between the support bars 3.

Dismantling of the container is carried out in the reverse order, while the structural elements are oriented in an oriented manner into returnable packaging (FIGS. 4 and 5).

In the box-free base 2, free of cargo, on the bottom 1, two side walls 6 are laid, folded together with the front side inward. Two end walls are stacked on top, which are folded adjacent to the front side with a 180 ° turn, with visors 9 inward, orienting the eyes 11 to the sides of the support 2.
