Description

The utility model relates to the field of cargo transportation, more specifically to devices (shields) used in shipping containers when transporting bulk cargo.

In the prior art, various variants of adaptations to shipping containers are known.

For example, from the source US 11142394 B1, published on 10/12/2021, a shield for shipping containers is known, which consists of crossed struts, a barrier panel and retainer panels installed behind the struts.

However, the disadvantage of this shield is the lack of design efficiency.

Also known from the prior art is US 6206623 B1, published on March 27, 2001, from which a shield partition used in shipping containers is known. The well-known partition-shield consists of several panels located one above the other.

This source of information was taken as the closest analogue to the claimed utility model.

The disadvantage of the closest analogue, as well as all known prior art, is the lack of functionality of the shield.

Thus, the objective of the claimed utility model is to eliminate the shortcomings of the prior art.

The technical result, which the claimed utility model is aimed at, is the simplification of both loading and unloading the container with bulk cargo.

The technical result is fully achieved by the set of features of the utility model declared in the independent claim.

The reusable shield for the transportation of bulk cargo in containers consists of side vertical posts connected in their middle parts by the axes of rotation of the upper and lower wings, on which the upper and lower wings are fixed, respectively. In the upper and lower parts of the uprights there are fixing protrusions designed to engage with the hooks of the upper and lower wings in their closed position. The hooks of the upper and lower wings are made with the possibility of rotation around the horizontal axes with the help of locking levers. Fixing brackets are hingedly mounted on the upper sash, and fasteners are installed on the lower sash, which, when interacting, ensure that the upper sash is fixed in the open position when the lower sash is in the closed position, and the lower sash is fixed in the open position when the upper sash is in the closed position.

On the side vertical racks there are fastening elements of the shield in the grooves of the container in the area of the doorway.

When the hooks interact with the locking projections, the locking levers are parallel to the flaps.

In the middle part of the side vertical posts, a lower sash opening/closing mechanism is installed in a removable manner, which contains horizontal beams, a drive, levers, hooks attached to the lower sash fixing levers, and an axis of rotation of the levers.

Further, the claimed utility model is explained in more detail by drawings, in which:

In FIG. 1 shows the declared shield with closed doors.

In FIG. 2 shows the declared shield with an open upper sash (side view).

In FIG. 3 shows the claimed shield with an open bottom flap (side view).

In FIG. 4 shows the declared shield with the installed removable mechanism for opening the flaps.

In FIG. 5 shows the declared shield with the installed removable mechanism for opening the doors and with the bottom leaf open.

Declared shield consists of vertical side posts (1), upper sash (2), lower sash (3) and a removable mechanism (4) for opening/closing the lower sash (hereinafter referred to as the mechanism).

On the side vertical posts (1) there are elements (5) for fastening the shield in the grooves of the container in the area of the doorway. Between the right and left side vertical posts (1), approximately in their middle parts, an axis (6) of rotation of the upper sash (2) and an axis (7) of rotation of the lower sash (3) are fixed. On the inner sides of the side vertical posts (1) there are locking protrusions (8) designed to interact with the locking hooks (9) of the upper and lower wings when they are in the closed position.

On the upper and lower wings there are levers (10) designed to rotate the locking hooks (9) using the rotary axis (11) to exit or engage with the locking protrusions (8).

On the upper sash (2) are hinged fixing brackets (12) designed to fix the lower or upper sash in the open position (see Fig. 2 and Fig. 3). When fixing the upper sash (2) in the open position (see Fig. 2) (used as a rule for loading the container with bulk cargo), the fixing bracket (12) engages with the fastener (13), the lower sash (3), which is in closed position. The fastening element (13) can be made in any known way, for example, in the form of a hook, loop or hole. When fixing the lower sash (3) in the open position (see Fig. 3) (used as a rule to unload the container), they are hooked onto the fixing bracket (12) by fasteners (13), while the upper sash (2) is in the closed position .

The use of the declared shield is carried out as follows: The declared shield is installed in the doorway of the container, placing the side vertical posts (1) in the openings of the container behind the frame beams and fixed with the fastening elements (5). Initially, the sashes are in the closed position. If it is necessary to fill the container with bulk cargo, by turning the levers (10) located on the upper flap (1), the hooks (9) disengage from the locking projections (8) and on the axis (6), the upper flap (2) is rotated and fixed in open position using the locking bracket (12). After filling the container to the level of the axis of rotation of the upper sash (2), the fixing bracket (12) is disconnected from the fastener (13) and the upper sash (2) is raised to an almost closed position, leaving a small gap between the upper edge of the upper sash and the upper edge of the doorway container for refilling the container with bulk cargo completely. After the container is completely filled, the upper flap (2) is closed and fixed in the closed position with the help of hooks (9) interacting with the locking tabs (8) by turning the levers.

When it becomes necessary to empty the container, the container doors open and by turning the locking levers (10) of the lower sash (3), the hooks (9) disengage from the locking projections (8) located in the lower parts of the side vertical posts (1), the lower sash (3) turns on the axis (7) of rotation and the contents of the container begin to spill out of the container by gravity. If it is necessary to fix the lower sash (3) in the open position, it is fixed on the fixing brackets.

After the container is completely empty, the shield can remain in this container, or it can be dismantled from it and installed on another container, and also, due to its overall dimensions, it can be located in any place convenient for this, without taking up much space, for example, on top of each other horizontally or next to each other - vertically.

In order to be able to use the claimed shield in large ports when unloading containers, where personnel access to the locking levers (10) is difficult, a removable mechanism (4) for opening/closing the lower sash is installed on the side vertical posts (1). Mechanism (4) contains horizontal beams (14), axis (15) of levers (16), levers (16), drive (17) and hooks (18).

The horizontal beams (14) of the mechanism (4) are fixed in the middle part of the side vertical racks (1) after opening the doors of the filled container, the pivot levers (16) are hooked onto the locking levers (10) with the help of hooks (18). Using a rigging crane, the container is located in the right place to unload the contents of the container, the drive (17) is energized and on the axis (15) of rotation, the levers (16) begin to turn and pull through the hooks (18) for the locking levers (10) forcing the uncoupling hooks (9) from the locking tabs (8). And then, when the levers (16) are rotated, the lower flap (3) is moved to the open position to empty the container.

Thus, when using the claimed shield, both with the opening/closing mechanism of the lower sash, and without it, the loading and unloading of bulk cargo is simplified.

The claimed shield is a reusable product and, due to its simple design, provides durable use with various containers.

The claimed utility model is new, since the totality of its essential features is not known from the prior art, and, accordingly, meets the condition of patentability "novelty".

The claimed utility model meets the condition of patentability "industrial applicability", since it can be used in industry.

Although the present utility model has been disclosed with reference to its preferred embodiments, this is not intended to limit the present utility model, those with general knowledge in the art of the present utility model may modify and implement it without departing from the idea and scope of the utility model, therefore , the scope of protection of this utility model should be governed by the scope specified in the utility model claims.
