SOFT CONTAINER FOR TRANSPORTING LIGHT LOOSE LOADS

Abstract

A soft container for transporting light loose loads comprises a receptacle in the shape of a rectangular parallelepiped with a volume exceeding 13 m3. Said receptacle has a charging neck on an upper base, a discharge valve on the bottom, and four soft perforated partitions arranged inside the receptacle. The container further comprises a sling structure, the slings of which are connected to one another on the bottom of the receptacle, and lifting loops of the sling structure have a detachable connection to the receptacle, proximate the upper base thereof, as well as being connected to one another by an additional load-distributing sling strap which, in turn, has a connection to the receptacle, proximate the upper base thereof. The sling structure also includes sling straps arranged along the outer perimeter of the receptacle.

Description

FIELD OF THE INVENTION

The invention relates to transportation industry and can be used to produce a heavy-duty bag for shipping bulk goods with low volumetric density, such as bulk construction materials, raw materials for the metallurgical industry, chemical products, raw sugar, grain, coffee, and other food cargos.

BACKGROUND OF THE INVENTION

In terms of technical nature, purpose, and achieved result, the most similar to the present invention is the Flexible Container “MK 14” (http://nttrans.net/ru/mk-14-10), which includes a receptacle with an upper loading aperture, a lower unloading aperture, and a power frame. This device also comprises a locking device, a power grid with lifting loops and a bottom.

This well-known device shows such a drawback as a small volume (13 m³), which makes it impossible to fill the whole useful space of the open wagon with bulk cargo with a low volumetric density of 0.78 t/m³ and less due to its cylindrical shape. This causes the loss of the useful space of the open wagon.

Thus, one cylindrical bag can hold up to 10 tons of light weight. More specifically, one 13 m³ sack can hold 10.14 tons of grain (with a volumetric density of 0.78 t/m³). The open wagon can hold 5 such bags. This means that a wagon, which can transport up to 67 tons, carries only 50.7 tons. In terms of logistics, this is economically unprofitable.

Hence, there is a flexible container for transporting and storing bulk goods (Ukrainian patent for invention No. 72054, published on Jul. 15, 2003), which includes a receptacle with an upper loading aperture, a lower unloading aperture, and a power frame. This invention also comprises a locking device, a power grid with lifting loops and a bottom. According to this well-known invention, a receptacle is arranged in a power grid and coupled to it in the upper section by a detachable joint, which consists of sequentially interconnected loops fixed on the receptacle and the power grid having the last group of loops shorted by a cord tie. Moreover, the continuation of the loops fixed on the receptacle is made as ribbons, placed obliquely to the threads of the base of the receptacle. The power grid has a bottom with an opening and a rim element connected to the unloading aperture of the receptacle, and the receptacle is equipped with sleeves having tape loops and a system of valves. One of the sleeves is fixed on the loading aperture of the receptacle.

SUMMARY OF THE INVENTION

The present invention is primarily aimed at increasing the volume of the receptacle and, as a consequence, increasing the payload volume of the wagon.

The set task is solved by providing the FLEXIBLE CONTAINER FOR TRANSPORTING LIGHT BULK GOODS with a receptacle with an upper loading aperture, a lower unloading aperture, and a power frame. According to the present invention, a receptacle is shaped as a rectangular parallelepiped with a volume exceeding 13 m³. It has a loading aperture on the upper base and an unloading valve on the bottom. It comprises four soft perforated partitions located inside this container, equipped with a sling assembly that connects to each other at the bottom of the bag. The load loops of the sling assembly have a detachable coupling with the flexible container at its upper base, as well as an additional load distribution sling, which in turn has a coupling with the container at its upper base, and sling straps located on the outer perimeter of the container.

The present invention addresses the problem of increasing the volume of the container and, consequently, the payload volume of the wagon by creating a bag of up to 17 m³, which has the shape of a rectangular parallelepiped that will fill the entire payload volume of the open wagon. Thus, it becomes economically advantageous to transport light bulk goods in the open wagon. When this target is achieved, 66.3 tons of grain will be transported in the open wagon (17 m³×0.78 t/m³=66.3 tons), which is basically 16 tons more than the known cylindrical sacks in the open wagon.

This is further enhanced by the fact that the proposed container has the shape of a rectangular parallelepiped and a volume greater than 13 m³ and is equipped with four perforated partitions.

These and other objects, advantages and features of the invention will become apparent upon review of the following specification in conjunction with the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

The utility model can be illustrated by the following drawings:

FIG. 1 shows a perspective view of a multipurpose container; and

FIG. 2 shows a sling assembly separately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A multipurpose container of the present disclosure has such basic components (see FIG. 1 and FIG. 2): Flexible container (1) is shaped as a rectangular parallelepiped with a volume exceeding 13 m³. It has a loading aperture (2) on the upper base and an unloading valve (3) on the bottom. It comprises four soft perforated partitions (4) located inside this container, equipped with a sling assembly (5) that connects to each other at the bottom of the bag (6). The load loops (7) of the sling assembly have a detachable coupling (8) with the flexible container at its upper base, as well as an additional load distribution sling (9), which in turn has a coupling (10) with the container at its upper base, and the sling straps (11) located on the outer perimeter of the container.

This device is operated as follows. Flexible container for transporting and storing bulk goods is used according to the well-known pattern: loading, transportation to the consumer, and unloading. Before loading the bulk check cargo whether the unloading valve (3) is closed. Then the container is lifted, suspended by the main slings (11), and connected to the hopper feeding bulk cargo. Then, the lower unloading valve (3) is released, through which the container's bulk cargo is discharged.

Hence, the utility model attains the objective of increasing the volume of the receptacle and, as a consequence, increasing the payload volume of the wagon.

Changes and modifications in the specifically-described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims as interpreted according to the principles of patent law including the doctrine of equivalents.
