Description

Field of technology

The invention relates to the field of transportation, handling and storage of bulk and loose cargo, bulk cargo weighing no more than 15 tons, including food (grain) cargo and certain dangerous goods according to UN classification, such as lump sulfur, ammonium nitrate, coal tar pitch, etc. The invention also relates to multimodal transportation of bulk cargo on various types of transport without reloading the bulk cargo from a reusable soft container, and to unloading bulk cargo from soft containers into a ship's hold or into open and closed bunkers.

State of the art

Flexible multi-use containers with a large load-bearing capacity have a composite structure consisting of a frame grid and an insert. Functionally, the container insert serves to hold the transported cargo and is attached to the frame grid, which performs the lifting function. The insert is equipped, among other things, with an unloading sleeve through which it is unloaded. Moreover, unloading can only occur in a suspended state, when the frame grid of the flexible container is held by a crane above the unloaded surface, for example, the hold of a ship, or a bunker, or a vehicle, etc. Unloading of the flexible container is carried out in various places, over the entire area of the ship's hold, while the flexible container is controlled remotely.

A soft container for transporting and storing bulk cargo is known from the prior art according to the patent for utility model RU 209570 U1, IPC B65D 88/16, 17.03.2022, characterized in that it contains a power grid with lifting loops, an insert located in the grid with a loading sleeve in its upper part and an unloading sleeve in its bottom part, respectively, upper and lower fastening frames, a bottom with an opening and a rim element combined with the unloading opening of the container is made in the power grid, a system of eight valves is fixed on the rim element for fixing the sleeve fixed to the unloading opening of the insert in the folded state, the system of eight valves has two locking assemblies, each of which includes metal rings on three valves and a metal oval ring on the fourth valve, a pin for locking and locking tapes, each The closing unit connects four valves by fixing three rings on a metal oval ring and closing them with a pin with a locking band, wherein the valves from the first group of four valves close the connections between the valves of the second group of four valves. According to the utility model, the insert of the soft container is attached at the top to the power grid through a fastening unit containing loop ties, part of which is fixed to the power grid, and the other part - to the surface of the insert. According to the specified utility model, in order to prevent spontaneous opening of the unloading device of the container, it is divided into two unchecking units, each of which has four metal rings on four valves and a pin for closing each group of valves. Thus, on each container, two pins (pins) are used to open its unloading device. In this case, unchecking two pins with a non-oriented position of the container is problematic and leads to a loss of unloading time.

A universal container for bulk cargo according to utility model RU 113724 U1, IPC B65D 88/22, 23.08.2011 is known from the prior art, characterized in that it contains a container with an upper loading opening and a lower unloading opening, a power frame, a sling structure formed by sling straps with loops at the ends is used as the power frame, the intersection points of which form the bottom of the sling structure, which is equipped with a protective detachable casing, wherein the container is made in the form of an insert, which is equipped with protective tunnels with the possibility of placing sling straps in them, the upper loading opening is made in the form of a sleeve, and the lower unloading opening is provided with loading and unloading valves, respectively, wherein at least one transverse power ring is connected to the liner using a detachable connection.

Before loading, the unloading sleeve is clamped with a power tape with loops at the ends and is pinned with the first pin of the unloading link. The free end of the unloading sleeve is rolled up and secured with a loop connection to the second pin of the unloading link, which simultaneously pins the metal rings with a cord located on the tops of the petals protecting the rolled unloading sleeve. Thus, the second pin pins two loops at once, which, under the weight of the load, force the pin, which forces the soft container to be unloaded (unpinned) in an oriented position and leads to a loss of unloading time.

The closest analogue of the proposed invention is a soft container for transporting and storing bulk cargo according to the patent for invention RU 2787606 C1, IPC B65D 88/16, B65D 88/22, B65D 90/20 11.04.2022, characterized in that the design of the soft container for transporting and storing bulk cargo contains a power grid with lifting loops and an insert made of film material located in the grid. The liner has a blind bottom, the bottom part of the power grid contains an unloading opening to which an unloading sleeve is attached, the container additionally contains a protective casing, which is located between the power grid and the liner, while the protective casing is made of a material stronger than the film material of the liner. The liner, the protective casing and the power grid are connected to each other by detachable joints. To protect the discharge sleeve from spontaneous unloading, a triangular valve is attached to the mesh loops onto the rolled-up discharge sleeve. To do this, insert the loops into the rings located at the tops of the triangle and lock the loops with pins, which are secured with safety tapes. To unload such a container, pull the lock of the protective valve toward you, manually unclip the valve and the unloading sleeve twist, as a result of which the unloading sleeve falls out of the center of the container. Here, too, the locked pin is constrained by two loops that hold both the unloading sleeve twist and its location in the unloading opening of the frame mesh.

This type of unloading is problematic and leads to loss of time in unloading the soft container and delays in loading the vessel.

Disclosure of the essence of the invention

The problem solved by the claimed invention is the creation of a design for a soft container for transporting and storing bulk cargo, which would allow for the unhindered unpacking and unloading of such a container in any weather conditions without preliminary orientation, while ensuring maximum tightness of the container liner.

The stated problem is solved in that a soft container for transporting and storing bulk cargo is made containing a frame mesh, an insert located in the frame mesh, made of fabric with a polymer coating, wherein the insert has a loading sleeve in its upper part and an unloading sleeve in its bottom part, the insert is provided with garter loops sewn along the circumference of the insert in its upper part and attached to the frame mesh by means of their connection with the loops of the frame mesh, a rim element is formed in the bottom part of the frame mesh, made of power tapes sewn together, triangular flaps are fixed to the rim element, forming a sealing unit, a loop is formed at the end of each of the flaps, into which a metal ring is threaded, characterized in that the sealing unit contains a cord tie with loops at the ends, threaded through the valve rings for tightening the valves and a sealing pin, wherein one of the valve rings is base ring and consists of two rings forming two tiers, fastened together by four crosspieces, wherein the valve loop and one of the loops of the cord tie are attached to the upper tier of the base ring, adjacent to the bottom of the soft container, while the sealing pin has a ring part at one of its ends and its rod end is threaded into the other loop of the cord tie, threaded through the opening of the base ring.

The declared soft container ensures a reduction in the time for loading and unloading operations, increased reliability, maximum safety of the cargo due to the elimination of spillage of the loaded material, as well as an increase in the strength of the container structure.

In this case, the jumpers can be arranged on the base ring in such a way that they form two smaller and two larger arcs on each tier of the ring, symmetrical to each other, while the valve loop and one of the loops of the cord tie are attached to the large arcs opposite to each other to eliminate difficulties when closing and unclosing the soft container.

In addition, the annular portion of the sealing pin is made in the form of an oval, wherein the large axis of the annular portion of the sealing pin can be located in the transverse direction relative to the longitudinal axis of the rod end of the pin to ensure the best fixation of the pin in the sealed position of the container, as well as for the convenience of subsequent unsealing of the soft container.

Implementation of the invention

The soft container 1 comprises a frame mesh 2 and an insert 3 located in the frame mesh. The insert comprises a loading sleeve 4 in the upper part of the insert and an unloading sleeve (not shown in the figure) in the bottom part of the insert. The insert 3 is provided with tying loops (not shown in the figure) located along the circumference of the insert 3 in its upper part.

The garter loops are attached to the frame mesh by connecting them to the loops 5 of the frame mesh.

Insert 3, placed in frame mesh 2, can be connected to it in the upper part by means of a detachable connection consisting of loops connected in series to each other, secured to insert 3 and frame mesh 2 with the closing of the last group of loops with a cord tie.

The garter loops can be attached to the frame mesh 2 directly, that is, the loops 5 of the frame mesh 2 and the garter loops of the liner can be tied using a strong ribbon tie.

The garter loops of the insert 3 can be attached to the frame mesh 2 by means of a loop lock formed by threading the subsequent garter loop of the insert into the previous garter loop of the insert, previously threaded into the garter loop of the frame mesh with tying the closing loop to the first loop with a strong ribbon tie. Such a scheme of connecting the insert to the frame mesh is called a "loop lock".

In the bottom part of the frame grid 2, a rim element 6 is formed, made of power tapes sewn together. On the rim element 6, triangular-shaped flaps 7 are fixed, forming a locking unit 8. At the end of each flap 7, a loop 9 is formed. A metal ring 10 is threaded into the loop 9 of each flap 7.

The closing knot 8 contains a cord tie 11 with loops 11a and 11b at the ends. The cord tie 11 is threaded through the rings 10 of the valves 7 for tightening them.

One of the valve rings is the base ring 12. Ring 12 consists of rings forming two tiers 12a and 12b, fastened together by four jumpers 13a, 13b, 13c and 13d.

The loop 9 of the valve 7 and the loop 11a of the cord tie 11 are attached opposite to each other to the upper tier 12a of the base ring 12. The upper tier 12a of the base ring is adjacent to the soft container.

The locking pin 14 has a ring part 14a at one of its ends, made in the form of an oval. The rod end 14b of the pin is threaded into the loop 11b of the cord tie 11, which is threaded through the opening of the base ring 12.

The jumpers 13a, 13b, 13c and 13d are arranged on the base ring 12 in such a way that they form on the tiers 12a and 12b two smaller arcs (a-c) and (b-d) and two large arcs (a-b) and (c-d), symmetrical to each other. The loop 9 of the valve 7 and the loop 11a of the cord tie 11 are attached to the large arcs (a-b) and (c-d), respectively.

The major axis of the annular portion 14a of the locking pin 14 is located in the transverse direction (perpendicular) relative to the rod end 14b of the pin 14.

Tiers 12a, 12b of base ring 12, jumpers 13a, 13b, 13c, 13d and locking pin 14 are made of metal.

A flexible reusable container with a large lifting capacity has a reliable two-circuit protection against spontaneous unloading. In this case, unloading of the flexible container is activated by pulling the pin (coin) from the loop of the tie cord. The coin is the end element of the unloading tape, which is made of a power tape, forming a loop at the other end. The unloading tape is pulled out manually together with the coin. Before unloading, the flexible container is oriented so that the unloading tape with the coin is located in the direction of application of the unloading force. During mechanized handling in ports of cargo arriving in flexible containers in transport vehicles, for example, in railway gondola cars, preliminary orientation of flexible containers before their loading does not ensure maintaining the oriented position when unloading them into the ship's hold. This is due to intra-port logistics, according to which soft containers are extracted in pairs from gondola cars by a reach stacker and placed in an intermediate warehouse in several tiers with delivery from only one side, and the intermediate warehouse is dismantled with the approach of reach stackers from different sides, and an additional complication in the process of delivering oriented soft containers is introduced by the fact that in each gondola car soft containers are transported five pieces, and the fifth container from the gondola car is placed in a stack one by one.

The only way to ensure the simultaneous unloading of several soft containers secured to the gantry crane cross-beam is to change the soft container locking unit. As shown in the description of the prior art, the pin (coin) of the second circuit for protecting the soft container from spontaneous unloading locks all eight valve rings, tying them together with a cord tie secured to one of the eight rings (the base ring), the loop end of which is threaded through seven rings and inserted into the base eighth ring, and locked with the pin. Such a sequence of the locking operation, in which several loops are installed on the pin and the pin is forced, leads to the pin becoming unwieldy and requiring unlocking in the oriented position of the soft container.

Even if one loop of the cord tie is left on the pin and the remaining loops are transferred to the cord tie, then in inclement weather conditions the unpinning process becomes unstable and is complicated by the fact that the pin must be turned in the opposite direction on a metal ring pressed to the pin by a multi-ton load. Moreover, it is necessary to turn the pin by transferring it through the ribbon end of the cord tie and the loop of the ring fastening to the valve fixed to the ring. In the application under consideration, unimpeded rotation of the pin is ensured by using a base ring 12 and a metal pin 14.

The basic two-tier ring 12 consists of metal rings forming two tiers 12a and 12b respectively. To the upper tier 12a of the basic ring 12, on one side, a loop 9 of one of the valves 7 is attached by the large arc (c-d) in such a way that the basic ring 12 adjoins the soft container. To the same tier of the ring 12, on the large arc (a-b), on the other side, a loop 11a of the cord tie 11 is attached. Loops 9 and 11a are attached to the large arcs (c-d) and (a-b) respectively so that the loops in the loaded state have the ability to shift and be installed relative to each other in the necessary natural position. Thus, the lower tier 12b of the base ring 12, facing outward from the soft container 2, remains free from the fastening of the valve loop 7 and the loop of the cord tie 11 on it, and the metal pin 14 can be freely rotated along its metal surface. The design of the pin 14 is improved in that its annular part 14a is made in the form of an oval, wherein the large axis of the annular part 14a is located in the transverse direction (perpendicular) relative to the longitudinal axis of the rod end 14b of the pin 14. Such a design of the pin 14, when unpinning in a non-oriented position of the soft container, allows the connecting loop 15 of the tape link to shift to the narrow part of the oval and provide a greater moment of the applied force for turning the pin 14 and unpinning the cord tie 11 in a natural direction.
