Description

The utility model relates to means for storing and transporting bulk, piece and loose cargo.

From the Russian Federation patent No. 224573 for a utility model, a container is known, comprising a base, side and end walls, a roof, which are connected by vertical posts and horizontal beams, forming a single rigid structure, upper and lower corner fittings, wherein the vertical posts consist of outer and inner parts with a reinforcing element, wherein the reinforcing element is installed close to the wall of the inner part of the vertical post.

From the Russian Federation patent No. 225668 for a utility model, a container is known, formed by a base, side and end walls, a roof, which are connected by vertical posts and horizontal beams, forming a single rigid structure, upper and lower corner fittings, in the lower part of the end wall there is an unloading hatch, containing an unloading opening, limited by beams, a hatch cover.

The disadvantage of analogues is their lack of reliability.

The container known from Russian patent No. 225668 was chosen as the closest analogue.

The technical problem solved by the proposed utility model is to eliminate the shortcomings of analogues.

The technical result achieved by the utility model consists in increasing the reliability of the cargo container.

The technical result is achieved due to the fact that in a cargo container containing a base, side and end walls, which are connected by vertical posts and horizontal beams, forming a single rigid structure, upper and lower corner fittings, an unloading hatch is made in the end wall, according to the utility model, a contact pad is fixed on the lower horizontal beam of the end wall, located above the lower surface of the lower corner fittings when the container is unloaded and located below the said lower horizontal beam to ensure the possibility of contact with the supporting surface when the container is loaded.

The contact pad can be made with a U-shaped cross-section, wherein the side sides of the contact pad are rigidly connected to the side sides of the lower horizontal beam, and the central section is located below the said horizontal beam and above the lower surfaces of the lower corner fittings.

The contact pad can be made in the form of a channel.

The contact pad can be made from a bent plate in the form of a bracket.

The contact area can be located 10÷15 mm above the level of the lower surface of the corner fittings.

The base may contain cross beams rigidly connected to the lower horizontal beams.

Contact plates can be rigidly fixed to the lower surfaces of the base cross beams, ensuring contact between the base of the loaded container and the supporting surface.

The claimed utility model is illustrated by figures.

The claimed cargo container comprises a base 1, side 2 and end 3 walls, which are connected by vertical posts 4 and horizontal beams 5, forming a single rigid structure; upper 6 and lower 7 corner fittings, and an unloading hatch 8 is made in the end wall 3.

On the lower horizontal beam 5 of the end wall, a contact pad 9 is fixed, located above the lower surface of the lower corner fittings 7 when the container is not loaded and located below the said lower horizontal beam 5 to ensure the possibility of contact with the supporting surface when the container is loaded.

The contact pad 9 is made with a U-shaped cross-section, wherein the side sides of the contact pad 9 are rigidly connected to the side sides of the lower horizontal beam 5, and the central section is located below the said horizontal beam 5 and above the lower surfaces of the lower corner fittings 7.

The contact pad 9 can be made in the form of a channel or can be made from a bent plate in the form of a bracket.

The contact area 9 (its central section, located between the side sections of the U-shaped profile) is located above the level of the lower surface of the corner fittings 7 by 10÷15 mm.

The base 1 may contain cross beams 10 rigidly connected to the lower horizontal beams 5.

On the lower surfaces of the cross beams 10 of the base, contact plates 11 are rigidly fixed, ensuring contact of the base 1 of the loaded container with the supporting surface.

In the loaded state, there is a deflection of the base 1 of the container, including the cross beams 10, as well as a deflection of the lower horizontal beams 5 of the base 1.

There are requirements according to which the base 1 and the lower beams 5 of the loaded container must rest against the supporting surface during transportation of the loaded container, or when it is in a stationary state.

For this purpose, the lower horizontal beams 5 are made such that they are located above the level of the lower surface of the lower corner fittings 7 by the amount of possible deflection, as a rule, the possible deflection of the beams and the base is estimated at 10÷15 mm depending on the dimensions of the container and the weight of the cargo. When the loaded container is on the supporting surface (for example, on the transport platform), the base 1, including the horizontal beams 5, will sag under the weight of the cargo and rest on the supporting surface, thus excluding deformation of the base 1 and horizontal beams 5 of the container.

However, such execution of the lower beams 5 of the container base is not possible in all containers. In particular, if the container has an unloading hatch 8 in the end wall, the lower horizontal beam 5 of the end wall is made lighter (and therefore has smaller dimensions) than the lower horizontal beam of the opposite wall. This is due to the need to secure locking devices and control devices to the lower beam of the end wall with the unloading hatch.

In order to prevent deformation of the lower horizontal beam 5 of the container base, contact pads 9 are attached to its lower part, protruding downwards beyond the said horizontal beam 5. In this case, the distance between the contact pad 9 and the lower surface of the lower corner fittings 7 corresponds to the deflection of the horizontal beam 5 - from 10 to 15 mm.

When a loaded container is located on a supporting surface, the lower horizontal beam 5 of the base with contact pads 9 will rest on the supporting surface, thereby eliminating the possibility of its deformation or damage resulting from such deformation.

The contact pads 9 on one side are stiffening elements that increase the rigidity of the lower horizontal beam 5 of the base and, accordingly, increase the reliability of the container.

On the other hand, contact pads 9 increase the area of contact of the container with the supporting surface, reducing the probability of deformation of the base 1, base beams 5 from the weight of the load, also thereby increasing the reliability of the container.

The contact pads 9 can be made in various ways, for example, in the form of a bracket, for this they are made from a bent sheet, or a ready-made profile - a channel can be used. The U-shaped cross-section of the contact pads 9 allows their central section to be located at the required level, corresponding to the level of deflection of the horizontal beam, and the side sections to attach the contact pads to the sides of the horizontal beam 5.

A loaded container manufactured in accordance with the claimed utility model will rest on the supporting surface with lower corner fittings 7, a lower horizontal beam 5 of the base located under the end wall 3 without an unloading hatch, contact plates 11, and also contact pads 9.

In this case, deformation from the weight of the cargo of all elements of the base 1, including the lower horizontal beam 5, made with smaller dimensions than the opposite horizontal beam 5, will be excluded. Consequently, the residual deformation of the base 1, including the lower horizontal beams 5, and the associated damage to the container (for example, skewing of the unloading opening), leading to the impossibility of further use of the container, is reduced.

Depending on the dimensions of the container, the number of contact pads can be 2 or more.

Thus, the claimed utility model ensures the achievement of a technical result consisting in increasing the reliability of a cargo container.
