Description

The utility model refers to means for storing and transporting products for industrial, household, military purposes with increased protective and operational characteristics and is intended for stowage, storage and transportation of mainly ammunition, explosives, electronics, electrical engineering, and other technically complex devices of any kind in any combinations. The technical solution can be used for operation in the conditions of troops, arsenals (bases, warehouses) and industrial enterprises.

From the existing state of the art, a container for storing and transporting explosive products is known, which has carrying elements and is a body made with the possibility of interconnection by the "thorn-groove" method and a hinged lid, fixed relative to it by locking elements, with a hinged lid on the outer horizontal surfaces lids and bodies are made of external stacking elements, offset in pairs by each other's dimensions (see, for example, RU 171142 U1, publ. 05/22/2017 and RU 188133 U1, publ. 04/01/2019).

In the known solutions, the body and the cover are made of sheet metal elements welded together. Making containers of metal affects the weight of the product as a whole, which significantly limits their number in a stack due to a significant increase in the load on the bottom box of the stack. This circumstance limits the operational capabilities of the container. In this case, the stacking elements are made to mechanically restrict the movement of products relative to each other in only one direction, in the opposite direction, movement is limited by anti-slip rubber elements, frictionally interacting with the stacking element of the adjacent box, which is not reliable, especially during transportation. In addition, the production of such products is not technologically advanced due to the large number of assembly operations, and the service life is limited due to the property of the metal to undergo oxidation.

The task to be solved by the claimed utility model is the creation of durable containers for storage and transportation of explosive and sensitive products, which, when applied, helps to increase the safety of the contents during the transportation and storage of containers in stacks, as well as to increase productivity during the transportation of goods, to efficiently use the warehouse area. during storage.

The problem posed in the proposed utility model is solved due to the fact that the container for storing and transporting explosive and sensitive products has carrying elements and is a body made with the possibility of interconnection by the “thorn-groove” method and a hinged lid fixed relative to it with locking elements. , while on the outer horizontal surfaces of the hinged cover and the body, external stacking elements are made, in pairs offset by the dimensions of each other, while, according to the technical solution, to ensure the interconnection of the body and the hinged cover, a conical groove is made at the end of the body wall along its entire perimeter, complementary in shape to a protrusion made along the perimeter of the hinged lid, fixed to the body by means of double-hinged hinges, while the stacking elements of the hinged lid and the body are made in pairs with cutouts and protrusions in plan, geometrically closed when stacked and containers made of composite material based on unsaturated polyester resin.

The stacking elements of the hinged cover and the body can be made in one piece with them.

Locking elements can be made in the form of hinged lever locks.

Carrying elements can be made in the form of pivoting brackets with limitation of their rotation in a horizontal position

Stiffening ribs can be made on the inner surface of the walls of the body.

On the outer vertical surface of the hinged cover and the body in the area of arrangement of the locking elements, stiffeners can be made.

The technical result achieved by the given set of features is to increase the stability of containers in stacks.

The causal relationship of these features with the claimed technical result is disclosed below in the text of the description.

The essence of the claimed device is illustrated by drawings that do not cover and, moreover, do not limit the scope of claims for this solution, but are only illustrative material of a particular case of its implementation, which depict:

Containers for storage and transportation of explosive and sensitive items are made of composite material based on unsaturated polyester resin. The container includes a housing 1 and a hinged lid 2. The hinged lid 2 is hinged on the housing 1 by means of double-hinged hinges 3 and is fixed relative to it with locking elements 4. The housing 1 and the hinged lid 2 are made with the possibility of interconnection by the thorn-groove method. For this, a conical groove 5 is made on the end of the wall of the housing 1 along the entire perimeter of the end (see Fig. 5), and a protrusion 6 (see Fig. 7) is made along the entire perimeter of the cover (see Fig. 7), complementary in shape to the conical groove 5.

On the outer horizontal surfaces of the hinged cover 2 and the body 1, the outer elements 7 of the stacking are made. Elements 7 of the stacking of the hinged cover 2 are displaced beyond the dimensions of the elements 7 of the body 1. Elements 7 of the stacking of one of the elements 1 or 2 have cutouts 8 in the plan (see Fig. 6), and the elements 7 of the stacking of the other of the elements 1 or 2 have protrusions in the plan 9 (see Fig. 3). The cutouts 8 and projections 9 of the stacking elements 7 are complementary in shape and provide a positive fit when stacking containers due to their pairwise displacement beyond each other's dimensions.

The container has 10 carrying elements. In a preferred embodiment, the carrying elements 10 are made on the transverse walls of the housing 1 in the form of pivoting brackets with a limitation of their rotation in a horizontal position.

The principle of operation of containers for storage and transportation of explosive and sensitive products is as follows.

Transportation by road, rail or air transport and storage in warehouses or bases of goods packed in containers is carried out when containers are stacked. The more container units a stack contains, the higher the productivity of cargo transportation and the efficiency of using the storage space during storage. On the other hand, the compilation of a large number of container units in a stack is possible only if the requirements for ensuring the safety of goods are met, which is achieved by the stability of the stack when exposed to both vertical static loads during storage of goods and dynamic loads that additionally arise during the transportation of goods. Stability of the stack is achieved by the correct and constant geometry of the container.

The geometry of the container changes as a result of its destruction or deformation. One of the conditions for ensuring the stability of the container, compiled in a stack, is to exclude the possibility of deformation and destruction of the device when it is exposed to static loads and loads arising in the process of operational transportation of goods. The rigidity and strength of the device are some of the factors to ensure that the geometry of the container remains unchanged, since strength refers to the device's ability to withstand stress without breaking, and rigidity refers to the device's ability to withstand deformation when stress is applied.

The manufacture of containers from a composite material based on unsaturated polyester resin determines a high level of its strength and hardness after complete solidification, wear resistance and long service life without deteriorating the physical characteristics of the product, as well as good resistance to high temperatures. In addition, unsaturated polyester resins have high chemical resistance to chemical attack. All these characteristics are necessary for a product intended for the transportation and storage of hazardous, such as in the case of ammunition and explosives, or sensitive, such as electronic devices, electrical engineering, products. At the same time, with a resistance comparable to that of metals, unsaturated polyester resin is 4 times lighter than metals, which allows minimizing the weight of the device while maintaining high rigidity and thereby reducing the load that occurs in the lower rows of the stack, reaching maximum values due to the pressure of the upper its ranks. Examples of the use of unsaturated polyester resin in the claimed solution can be isophthalic unsaturated polyester resin, orthophthalic unsaturated polyester resin, terephthalic unsaturated polyester resin.

To further increase the rigidity of the product, in some embodiments of the container, stiffening ribs can be made on the inner surface of the walls of the body 1.

After placing the cargo in the container, the body 1 is closed with a hinged cover 2. The geometry of the container changes as a result of a violation of the parallelism of the planes of the bottom of the body 1 and the hinged cover 2, which can occur during the operation of the container when it is closed under the influence of a human factor (inattention, haste, etc.). etc.). To ensure the correct positioning of the hinged lid 2 relative to the body 1 when closing the container, double-hinged hinges 3 are used as hinges, having two pivot axes located at a distance from each other, one of which is the axis of rotation of the plate fixed to the hinged lid 2, and the other is the axis of rotation of the plate mounted on the body 1. This design of the hinges makes it possible for the hinged cover 2 to move in two directions - vertical and horizontal. When closing the container, the hinged lid 2 is lowered onto the end of the housing 1 from top to bottom with the simultaneous unhindered placement of the conical protrusion 6 of the hinged lid 2 in the conical groove 5 of the housing 1 along its entire perimeter with full conjugation of the surfaces of the protrusion 6 and groove 5, due to the complementarity of their conical shape and implementation along the entire perimeter of the end of the body 1 and the hinged cover 2. Thus, distortions in the installation of the hinged cover 2 are eliminated and the planes of the bottom of the housing 1 and the hinged cover are parallel plates or can be connected by flexible connection. To further maintain the reached position of the hinged cover 2, it is fixed relative to the body 1 by locking elements 4, which are preferably made in the form of hinge lever locks. In addition, due to the implementation of the groove 5 and the protrusion 6 along the entire perimeter of the corresponding parts of the container, the possibility of displacement of the hinged cover 2 relative to the body 1 at subsequent stages of the container operation after closing is excluded. In some embodiments, for additional protection against displacement of the hinged lid 2 relative to the body 1 during the operation of the container, on the outer vertical surface of the lid and the body in the area where the locking elements 4 are located, stiffeners can be made to protect against arbitrary opening and / or damage to the locking elements 4. To give the product additional tightness, the groove 5 can be additionally equipped with a rubber or polyurethane seal.

Further, a stack is made of several container units using the carrying elements 10. In this case, the stacking elements 7 of the hinged cover 2 of the lower container interact with the elements 7 of the stacking of the body 1 of the upper container, due to the complementarity of their shape and their pairwise displacement for the dimensions of each other, providing geometric closure of the specified elements. In this case, a mechanical limitation of the movement of the upper container relative to the lower one is achieved, both in the longitudinal and transverse directions, which ensures an increase in the stability of the container in a stack under static and dynamic loads. The implementation of the container from a composite material based on unsaturated polyester resin determines the technology for manufacturing containers, in which the stacking elements 7 of the hinged lid 2 and the body 1 are made in one piece with them, which affects the accuracy of their placement and, therefore, improves the quality of their interaction with each other when stacking, which also has a positive effect on the stability of the stack.

A distinctive feature of this container from similar developments is the possibility of stacking it together with a standard wooden container (see Fig. 2). Samples of container products made in accordance with the proposed utility model have successfully passed operational tests for stack stability up to 5 meters. The described technical solution contributes to the creation of containers for storage and transportation of explosive and sensitive products, providing increased safety for the cargo packed in it during transportation and storage of containers in a stack, as well as increasing productivity during the transportation of goods and efficient use of warehouse space during storage.
