Description

[0001] Invention relates to the field of transport and can be used for storage of bulk cargoes such as bulk construction materials, raw materials for metallurgical industry, chemical products, raw, grain, coffee and other food goods.

[0002] It is known a soft container for cargoes transportation and storage (Patent RU 2228287, publ. 10.05.2004), which contains a hoses and bottom. The bottom of the container is formed by incurvate lobes from outside to the container center coupled with the container hoses with four long and located between them four short lobes, and the last ones are located over the overlapping long lobes and tied up with the rope element to the center of the bottom, meanwhile edges of each short lobes are stitched over the neighboring long lobes, what provides the hermiticity of the bottom in the places of the lobes junction at their maximum possible opening during the container unloading. The disadvantage of this design is its low reliability.

[0003] The closest to an invention, which is stated according the technical nature, purpose and output that is achieved is a soft container for transportation and storage of bulk cargo (Ukraine invention patent Nº 72054, publ. 07.15.2003), which contains a tank with a top loading hole and the bottom unloading hole, a force cage. The invention also includes a locking device, power mains with lifting loops and bottom. In compliance with this well-known invention , the tankage is located in the power mains and connected to it at the top with in-cut connection, which consists of a successively ganged with one another loops reinforced on tank and on the power mains with the bridging of the last group of the loop with the force lace and the loops prolongation which are reinforced on tank are made in the form of tapes placed at atilt to the direction of the bottom thread and container fabric drain, in the power mains made a hole in the bottom with the rim element connected to the tankage discharge opening, meanwhile container equipped with sleeves with metal belt for pumping under pressure and a system of valves; one of the sleeves strengthening at the tankage discharge opening.

[0004] The main disadvantage of this known device is that it is inconvenient to use. There are several reasons. The container consists of two parts - the power grid in the frame and the inner liner, which is mounted at the top of the liner to the force split frame method.

[0005] Using this product provides airtightness during the loading, the loading rate, but it is a great inconvenience for repairing the damages of the container due to the fact that the outer part of the container is covered by a mains, which isn't attached to liner throughout all perimeter not, except the upper part. That is why during the work with the container appear the difficulties: before its installing for loading it is necessary to check, if the inner liner wasn't twisted. As far as liner does not follow the contour of the power framework in an empty state, during the loading it needs accept the form of the power framework under the pressure of the loadable material, and only after a collision with the framework contours the load on the liner is diminishing and the main load takes the force frame. Also, during the operation of the container is the probability of the engage of the force framework over the irrelevant materials, which can damage the force framework and thereby phase out the whole container.

[0006] The main object of the invention is to improve the ease of operation during the work the large-tonnage bulk cargoes.

[0007] The problem is solved by the fact that the universal container for bulk cargoes includes a tankage with the upper charging opening and bottom discharge opening, a force framework. In accordance with the invention, as the force framework used sling frame construction formed by sling tapes with loops at the ends, traversal places of which form the bottom of the sling frame construction, equipped with the protective. Tankage is made as a liner provided with protective tunnels with the possibility of placing into them the sling traps, the upper charging opening is made in the form of a sleeve, the bottom discharge opening provided with loading and unloading valves accordingly. With the liner connected at least one force cross-ring with split connection.

[0008] In accordance with one of the variants of the invention selling the composition of the protective shroud with the opening includes the lobes on the ends of which the rings are fixed through which permeate the cord, settled with the lock. Housing is equipped with a detachable mechanism, which consists of a loop located at the bottom of the sling frame construction and loops located along the perimeter of the protective cover. The loops are connected through the force trap.

[0009] In accordance with another variant of the invention selling, the liner is connected to the sling straps with pawl, which consists of tape connected with the liner and tape joined to a liner and the tape joined to with sling tape with the clasp. In the sling construction made a opening with the ability to accommodate the discharge valve in it, which consists of plexiform tapes, at the ends of which loops connected by lock are located.

[0010] The invention solves the problem of improving the ease of usage with the help that the mobility provided by the repair replacement of spare parts container. Meanwhile the entire container isn't phased out in case of breakage of one of its constituent parts. The inner liner is incorporated with the force framework, but meanwhile the connection is split. Thanks to the protective tunnels the maximum possible damage of the stop construction is reduced from the external factors that may lead to the exit the container out of the work of. So, to replace the damaged cross-ties disconnect the laces and release them, and replaced by a new ones and fix them by connecting laces. There is no need to dismantle any other elements of the container and remove it from exploitation. Thus, it is occurred a portable replacement of the damaged ring under conditions of continuous container operation.

[0011] After the wear (attrition) of protective cover it's replacement is implemented is s following way. When the container is empty a force strap is released, thus it divides the bottom of the sling construction with a protective cover. The replacement is carrying out by a new one and connecting with the tape. This process of replacing of the protective cover also does not require the removal of the container from the operation.

[0012] After the inner bush wore out it is removed all the force rings and release the sling tapes. Thus easy container installation and dismantling is provided.

[0013] Meanwhile the container contains all previously known helpful properties of containers, such as the hermetic unloading-loading, due to the presence of elements such as the sleeve. All this allows to create a universal container. Depending on the material of the liner 1 in a universal container any loose cargoes can be transported (food or chemical substances).

[0014] The invention is illustrated by the following drawings, where fig. 1 shows a general look; fig. 2 - type of container in axonometric state; fig. 3 - section A-A of fig. 1; fig. 4 - a top look of the main sling construction; fig. 5 - look of the protective cover; fig. 6 - construction of the closing-opening of the unloading valve of the inner liner with the lock.

[0015] Universal container has such basic components (see fig. 1 and fig.2): liner 1 with a protective tunnels 6, loading valve 2 and unloading valve 14, lifting loops 4, located at the ends of the sling traps 8, which are connected with one another in a bottom 9 of the sling construction 20, the force transversal ring 5, the protective cover 16. Bush 1 placed in sling construction 20 (fig. 1 and fig. 6), secured by pulling sling traps 8 in the protective tunnels 6, along the entire height of a liner. This method of fixing not only connects the sling taps 8 with a bush 1 and also allows the liner 1 totally repeat volume of the container. Liner 1 is not able to twist being inside the sling construction and is a holistic product in the form of a cylinder. Also, the additional liner fastening 1 to construction traps 8 is in the upper part with the locking pin, which consists of trap 17, joined to a liner 1, trap 18, joined to the sling trap with a fastener 19 (see fig. 3). The liner 1 fixing in its upper part can be also performed by other materials, such as loops and rubber bands, coupled with the help of carabine or other materials.

[0016] At the charging opening 2, which has the shape of the sleeve and is the neck of the liner, 1 at the outer part there is the lock valve 3 in the form of lace, the purpose of which is the blockage of the charging opening 2 after loading, which also serves to protect cargo from moisture, dust, and protects it from collision with the environment (see fig. 4). At the discharge opening 14, which also has the shape of hose from the outside there is a overload valve 13, which is a junction of traps 23 with loops 22. Traps 23 may be made of any hard flexible material or of round-woven materials. The loops 22 can also be made of plastic, iron, or of the same material, of which the traps are made 23.

[0017] Closing of the discharge opening 14 in the form of a sleeve happens due to gathering and wringing out by traps 23 and lock 24 fixation in the in turn connected loops 22 (see fig. 4). This connection prevents at unloaded state of the unauthorized actuation of the discharge valve 13. In addition, there is no need to use disposable discontinuous control laces to prevent the opening of the protective cover 16.

[0018] The protective cover 16 may be made of a hard reinforced fabric, laminated, for example, by polyvinylchloride (see fig. 5). It is produced by thermic welding, and also can be manufactured in other ways, for example it can be stitched. Can be used other materials, resistant to the demolition and water resistant, such as polyester, etc. The protective cover 16 is fastened to the bottom 9 of the sling construction 20 with split mechanism 28 by junction with one another loop 25, 26 using the power traps 27. The fastening is on the inside part of the cover 16 and the bottom 9, in order to avoid external mechanical damages of this junction. It can be also performed on the outer part of the cover 16 and the bottom 9. This junction allows quick replacement of the protective cover 16 after the depreciation, without touching the entire container or sling construction 20. It is also possible to fasten the liner 16 with other detachable mechanisms, such as traps, fasteners, etc. The liner 16 connection with the basic design of sling construction 20 may be also performed by not split way for example such attachment may be carried out by thermic welding, coupling technique or other methods of fixation.

[0019] Protective cover 16 has an opening 29. Accord the example at the protective cover 16 made the lobes 10 with rings 11 at the ends which are made of the same material as the protective cover 16, the rings are made by thermic welding of the material. Such a method of manufacturing is in advantage compared to production by cross-linking products, as the puncturing the material is excluded, thereby increasing its strength. The rings 11 may also be made of other materials. Opening 29 of the protective cover 16 is closed by pulling the cord 15 through all the rings 10 and 11 petals of its fixation with the lock 12.

[0020] The transverse force rings 5 are closed, and are made of hard force trap intended for fixation of transverse container capacity in the required diameter. They do not allow container inflation by cargo pressure. Transverse power ring 5 fastened on the perimeter of the container with fixing laces 7, which are sewn to the outer side of the protective tunnel 6. The Number of fixing laces 7 on a one tunnel 6 corresponds the number to the number of the transverse force rings 5. Also, the locking laces 7 can be additionally placed between the six tunnels to enhance retention. This connection is detachable, and each force ring 5 is independent in the general construction of the container and shall be separately replace after wear or damage, meanwhile it does not hurt whole construction of the container. Also, the force ring 5 can be fitted with other detachable junctions, such as loops. The force ring can 5 be made of different hard materials that can withstand the pressure and the corresponding load, such as polypropylene trap, polyester trap, metallic rope. Force Ring can be made from such materials as polyether, polyamide, or other hard material. They can also be detachable.

[0021] Sling construction 20 is a interlacing of two, four, or more than eight sling traps with loops 4, executed on one or two ends. Their attachment is carried out in places of interlocking by stitching or thermic welding. Places of ribbons interlacing form a square, the inside of which a opening 21 for the unloading valve 13. The Places of sling belt interlacing 8 can form any geometric figure, depending on their number, such as a polygon. Depending on the diameter of the inner liner 1, around the opening 21 additionally may be attached (sewn or welded) traps around the perimeter, thereby forming a bottom area 9 of the sling construction 20 which is made of any hard fabric material such as polyester, polyamide, etc. It can also be made of metal rope. The trap 30 with the lock 24 and the lock 12 mounted on one of the transverse of the force rings 5.

[0022] The device is used in a following way. The soft container for transportation and storage of the bulk cargoes work according the well-known scheme: loading, transportation to the consumer, the unloading. Before loading bulk cargo is checking if the discharge opening is closed 14 with the help of valve 13. Then pick up the container suspend it with the loops 4 and connect the charging opening 2 with hopper feed of bulk cargo. After loading the loading opening 2 is closing by using the charging valve 3. For unload the container it is necessary to pull the trap 30 and then first lock 12 is pulled automatically, revealing the opening 29 of the guard cover 16. At the same time release the opening 14, that also automatically opens with the help of lock 24, through which pour bulk cargo of the container.

[0023] Container dismantling in case of damage of one of its parts realized is the following way. To replace a transverse damaged force ring 5 sever laces 7, release it and replaced with a new one fixing it by connecting laces 7. There is no need to dismantle any other elements of the container and remove it from exploitation. Thus, there is a mobile replacement of the damaged ring 5 during continuous exploitation of the container. After the wear (attrition) of the protective cover 16 its replacement is making in a following way. At the empty state of the container release a power trap 27, thereby disconnecting the bottom 9 of the sling construction 20 with the guard cover 16. Carrying out its replacement by a new one and connect with the laces 27. This process of replacing of the protective cover 16 also doesn't require the removal of the container from the exploitation. After wear of the inner liner 1 all power rings 5 are removes with the help of laces 7separation and subsequent separation of the upper fixing traps 17 and traps 18 with the help of fasteners 19. Then sling construction 20 is disconnected from the liner 1 by releasing the sling traps 8 through tunnels 6. After this the new liner 1 is collected in the reverse order.

[0024] Thus, the invention achieves the task of improving the usage of the work large-tonnage bulk cargoes.
