Description

FIELD OF TECHNOLOGY

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

BACKGROUND

A covered wagon is known (Design and calculation of wagons: Textbook for high schools of railway transport. Edited by V. Lukin M .: UMK MPS of Russia, 2000. 731 p. S. 476) containing mounted on two undercarriage a body having side and end walls on which the roof is mounted, while the side walls are made in the form of sliding panels.

Known is a covered wagon with movable side walls and a roof for packaged and piece goods (RF patent No. 79854 for utility model, IPC B61D 3/00, published January 20, 2009), containing a frame mounted on running trolleys on which a body with flooring and lower guides for moving side walls, end walls having vertical power struts, reinforcing beams and casing, a roof having a longitudinal ridge connecting end walls with guides for moving side walls and roof, and a eniya side walls and a roof, located on the side of end walls.

A covered wagon is known (RF patent No. 39315 for utility model, IPC B61D 39/00, published July 27, 2004), comprising a body mounted on running trolleys having side and end walls, a floor, a roof, and rails located on the side wall, and sliding doors made with the possibility of moving in these rails, with each sliding door made in the form of a part of the side wall, extending from the middle of the body to the end walls. This solution is selected as a prototype.

A disadvantage of the known covered wagon is a decrease in body volume resulting from the placement of a side wall with a displacement inward of the body to enable the door to be moved 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, the disadvantage of the known covered wagon is the high mass of containers, 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 cover part of the body, for example, to protect it from atmospheric influences.

The technical problem to which the proposed utility model is directed is the reduction in body volume resulting from the placement of a side wall with a shift inward of the body relative to the door to ensure its movement along the wagon.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The inventive covered wagon comprises a body mounted on running trolleys having side walls and end walls, a roof, upper and lower guides located on the side wall, and a door configured to move in said guides, the door being folded in the shape of an accordion folded outside the body, and the upper and lower guides are located at the same vertical level with the side wall.

The technical result that is achieved by using the claimed utility model is to increase the internal volume of the body of a covered wagon while maintaining the dimensions of the wagon.

Thanks to the proposed design of the door of the covered wagon, it is possible to arrange the side walls with the body moving outward by the thickness of the side wall, which allows to increase the internal loading volume of the body with the door open and closed and to exclude interference when placing cargo in the wagon body. Consequently, the completeness of using the overall dimensions of the carriage increases.

According to one implementation option, the possibility of folding the door in the form of an accordion is provided by making it from a flexible material, including rubber and fabric material.

According to another embodiment, the possibility of folding the door of the side wall in the form of an accordion is provided by performing it from a set of articulated panels. In this case, an aluminum alloy or composite material can be used as the panel material. The use of these materials additionally provides a reduction in the tare weight of the covered wagon.

According to another embodiment, the door in the closed state can have a length corresponding to the length of the side wall, and can be folded to any of the end walls.

In addition, the car may additionally contain at least one other 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, said doors can be further folded toward the center of the side wall.

According to another embodiment, the covered wagon may comprise three doors sequentially located along the side wall, wherein the outer doors are foldable to the end walls, and the middle door is foldable to the center of the side wall.

According to another embodiment, the side wall may have fixed cantilever parts, while the door is located between these cantilever parts and can be folded to any of the cantilever parts.

According to another embodiment, the side wall may have fixed cantilevered parts, and the car may further comprise at least one door, wherein said doors are located between the cantilevered parts and are foldable thereto.

According to another embodiment, the covered wagon may comprise means for securing the door in the open position.

In all the considered implementation options, it is also possible to change the width of the doorway to the required limits, which simplifies loading of cargo of various sizes, and also provides the loader with access to different parts of the internal volume of the body of the covered wagon, which in turn provides increased efficiency of loading and unloading operations.

IMPLEMENTATION OF A USEFUL 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 comprises a body 2 mounted on the bogies 1, having side walls 3 and end walls 4, a floor (not shown), a roof 5, upper rails 6 and lower rails 7 located on the side wall, and also a door 8 made with the ability to move in these 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 extends beyond the body (Fig. 3), and when closed, 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 length of the door 8 in the closed state corresponds to the length of the side wall 3, i.e. passes from one end wall 4 to another. When this 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, for example, rubber or fabric material. In addition, the door 8 may include articulated panels 9, each of which can be made, for example, of aluminum alloy or composite material.

In another embodiment, the covered wagon may contain two doors 8, sequentially located on the side wall 3 (see Fig. 4). In this case, the doors 8 are made with the possibility of folding to the end walls 4. In addition, the possibility of their folding to the center of the side wall 3 (not shown) can be further provided.

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

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