Description

FIELD OF TECHNOLOGY

The claimed utility model relates to the field of railway transport, namely to covered wagons and the design of their doors.

BACKGROUND OF THE INVENTION

A covered wagon is known (Design and calculation of wagons: A textbook for universities of railway transport. Edited by V. V. Lukin. a body having side and end walls on which a roof is installed, while the side walls are made in the form of sliding panels.

A covered wagon with sliding side walls and a roof for packaged and piece cargoes is known (RF patent No. 79854 for a utility model, IPC B61D 3/00, published on January 20, 2009), containing a frame mounted on undercarriages, on which a body with flooring and lower guides for moving the side walls, end walls with power vertical posts, reinforcing beams and sheathing, a roof with a longitudinal ridge connecting the end walls to each other, with guides for moving the side walls and the roof, as well as a mechanism for moving the side walls and the roof, located on the side of the end walls.

A covered wagon is known (RF patent No. 39315 for a utility model, IPC B61D 39/00, published on July 27, 2004), containing a body mounted on undercarriages, having side and end walls, a floor, a roof and rails located on the side wall, as well as sliding doors movable in said guides, wherein each sliding door is made as part of a side wall extending from the middle of the body to the end walls. This solution was chosen as a prototype.

The disadvantage of the known covered wagon is the reduction in body volume resulting from the placement of the side wall with an offset inside the body to enable the door to move relative to the side wall along the wagon without going beyond its dimensions, while such a shift is maintained both in the open position and in the closed position.

In addition, a disadvantage of the known covered wagon is the high tare weight, which, when transporting goods of low density, will not allow full use of the increased axial load.

Also, the well-known covered wagon does not provide efficient loading and unloading operations, when it is advisable to flexibly adjust the width of the doorway, provide variable access to the entire internal volume of the body and close part of the body, for example, for weather protection.

The technical problem, which the proposed utility model is aimed at, is the reduction in the volume of the body, resulting from the placement of the side wall with an offset inside the body relative to the door to ensure its movement along the car.

DISCLOSURE OF THE ESSENCE OF THE UTILITY MODEL

The inventive covered wagon contains a body mounted on undercarriages, having side walls and end walls, a roof, upper and lower guides located on the side wall, as well as a door movable in said guides, the door being foldable in the form of an accordion with placement in the folded state outside the body, and the upper and lower guides are located at the same vertical level with the side wall.

The technical result, which is provided when using the claimed utility model, is an increase in the internal volume of the covered wagon body while maintaining the dimensions of the wagon.

Thanks to the proposed design of the door of a covered car, it is possible to position the side walls with an offset to the outside of the body by the thickness of the side wall, which makes it possible to increase the internal loading volume of the body with the door open and closed and to eliminate interference when placing cargo in the car body. Consequently, the completeness of the use of the dimensions of the car increases.

According to one embodiment, the ability to fold the door in the shape of an accordion is provided by making it from a flexible material, including rubber and fabric material.

According to another embodiment, the accordion-shaped side wall door can be folded by being formed from a set of hinged panels. In this case, aluminum alloy or composite material can be used as the panel material. The use of these materials additionally reduces the tare weight of the covered wagon.

According to another embodiment, the closed door may have a length corresponding to the length of the side wall and may be foldable to any of the end walls.

In addition, the car may additionally contain at least one more door located on the side wall, while the total length of these doors in the closed state corresponds to the length of the side wall. Moreover, these doors can be made with the possibility of folding to the end walls. In another embodiment, these doors can be additionally made with the possibility of folding to the center of the side wall.

According to another embodiment, the box car may comprise three doors arranged in series along the side wall, with the outer doors being foldable towards the end walls and the middle door being foldable towards the center of the side wall.

According to another embodiment, the side wall may have fixed cantilever parts, wherein the door is located between said cantilever parts and is foldable to any of the cantilever parts.

According to another implementation variant, the side wall may have fixed cantilever parts, and the car can additionally contain at least one more door, while these doors are located between the cantilever parts and are made with the possibility of folding to them.

According to another implementation variant of the covered wagon may contain means for locking the door in the open position.

In all considered implementation options, the possibility of changing the width of the doorway within the required limits is also achieved, which simplifies the loading of cargo of various dimensions, and also provides access for the loader to different parts of the internal volume of the boxcar body, which in turn improves the efficiency of loading and unloading operations.

IMPLEMENTATION OF UTILITY MODEL

In FIG. 1 shows a general view of a covered wagon according to a preferred embodiment of the proposed utility model. The proposed covered wagon contains a body 2 mounted on undercarriages 1, having side walls 3 and end walls 4, a floor (not shown), a roof 5, top guides 6 and bottom guides 7 located on the side wall, as well as a door 8 made with the possibility of movement in the specified guides 6 and 7. The door 8 is made with the possibility of folding in the form of an accordion. In the folded state, the door 8 protrudes beyond the body (Fig. 3), and in the closed state, the door 8 is essentially at the same vertical level with the side wall 3 due to the placement of the upper and lower guides 6 and 7 essentially at the same vertical level with the side wall 3.

As shown in FIG. 1, the closed length of the door 8 corresponds to the length of the side wall 3, i.e. extends from one end wall 4 to the other. In this case, the door 8 is made with the possibility of folding to any of the end walls 4.

The door 8 may be made of a flexible material such as rubber or fabric material. In addition, the door 8 may include hinged panels 9, each of which may be made of, for example, an aluminum alloy or a composite material.

In another embodiment, the covered wagon may include two doors 8 arranged in series on the side wall 3 (see Fig. 4). In the case under consideration, the doors 8 are made with the possibility of folding to the end walls 4. In addition, they can additionally be folded to the center of the side wall 3 (not shown in the drawings).

In another embodiment, a covered wagon may contain three doors 8 (see Fig. 5), the outermost of which are folded to the end walls 4, and the middle one - to the center of the side wall 3.

According to another embodiment, the covered wagon may include fixed cantilever parts 10 (see Fig. 6) and two doors 8, which, when opened, each fold to the corresponding cantilever part 10. Instead of two doors 8, one door 8 can be made, made with the possibility of folding to any of the console parts 10.
