The utility model is shown in the drawings, where:

- in Fig. 1 - covered freight wagon, general view;

- in Fig. 2 – sash of a sliding door of a freight car, view of the inside;

- in Fig. 3 - a leaf of a sliding door of a freight car, a local view of the outside, isometric projection;

- in Fig. 4 – the same, a local view of the inner side of the freight car sliding door leaf;

- in Fig. 5, 6 - a device for rolling back the sliding door leaf, local cuts, with different designs of end pushers.

The device for rolling back the leaf 1 (Fig. 1) of the sliding door of the body 2 of the freight car contains a handle 3 (Fig. 2).

The handle 3 is pivotally connected to the end pusher 4 (Fig. 3). The end pusher 4 is placed in the guide sleeve 5 (Fig. 4) with the possibility of rotation around its longitudinal axis using the handle 3. The guide sleeve 5 is mounted with its hole on the cylindrical pin 6, which is mounted on the stop bracket 7, fixed on the leaf 1 of the sliding door of the body 2 freight wagons. The axis 8 of the handle 3 is mounted on the bearing bracket 9, rigidly fixed on the guide bush 5. A groove 5.1 is cut in the wall of the guide bush 5 (Fig. 5), in which the drive end 3.1 of the handle 3 is located, kinematically connected with the end pusher 4. Working end 4.1 end pusher 4 is placed in a through hole 10, made in the vertical strapping 11 of the sliding sash 1. The guide bushing 5 is placed between the stop bracket 7 and the strapping 11 of the sliding sash 1. The guide bushing 5 is mounted from one end on the cylindrical pin 6, and is held by its other end using an end pusher 4, the working end 4.1 of which is permanently placed in the through hole 10 of the vertical trim 11 of the sliding sash 1.

In the end pusher 4, a groove 4.5 can be made, in which the drive end 3.2 of the handle 3 is located.

The guide sleeve 5 and the handle 3 can be mounted on the inner side of the leaf 1 of the sliding door of the body 2 of the freight car and covered from the outside with a protective cover 12 installed on the outside of the leaf 1 of the sliding door of the body 2 of the freight car.

The end pusher 4 can be made with a guide groove 4.2 (Fig. 6), with which the end pusher 4 is installed in the through hole 10 of the vertical trim 11 of the sliding sash 1. The working end of the end pusher 4 can be made with a thrust flange, for example, in the form of a thrust washer 4.3. In this case, the drive end 3.2 of the handle 3 interacts with the end face 4.4 of the end pusher 4.

The technical result, which consists in increasing the convenience and efficiency of using the sliding door of the freight car body, is achieved as follows.

When the sliding door of the body 2 of the freight car is opened, the leaves 1 roll back along the guides 13. In this case, a situation arises when, to start rolling back the leaves 1, it is necessary to apply great efforts, since the leaves 1 are in contact with each other by sealing devices that hold the shifted leaves 1 in a closed, closed position . Also, dust, snow, ice can accumulate in the guides 13, which presents obstacles for the start of movement and advancement of the flaps 1 along the guides 13. The use of auxiliary means in the form of crowbars, levers is not always possible due to the tight mutual closing of the flaps 1. In this case , to start the movement of the valves use the proposed device.

To do this, the handle 3 is transferred to a horizontal position, perpendicular to the plane of the sash 1, while turning the guide sleeve 5 on the cylindrical pin 6 and on the end pusher 4, the working end 4.1 of which is located in the hole 10 of the vertical trim 11 of the sliding sash 1. After that, force is applied to the handle 3, which, turning on the axis 8, interacts with the end pusher 4 with its drive end 3.1, moves it along the guide sleeve 5 in the direction of the vertical strapping 11. The working end 4.1 of the end pusher 4, resting with its end against the vertical strapping of the adjacent leaf (not shown) , mutually pushes the side pusher 4 of the sash 1 of the sliding door, creating a gap between the sashes, which, if necessary, can be used for further forced rolling of the sashes 1 of the sliding door using other improvised means, for example, crowbars, levers.

If the guide sleeve 5 and the handle 3 are placed on the inner side of the leaf 1, inside the body 2, this device can be used when the operator is inside the body 2, during loading and unloading, during the repair or maintenance of a freight car.

The efficiency of using the sliding door of the freight car body is achieved by reducing the time for the initial stage of moving the jammed doors 1 of the sliding door. The convenience and safety of using the sliding door of the freight car body of the proposed design is increased due to the application of an opening force in the middle part of the flaps 1, which reduces the distortion of the flaps and jamming and does not require much effort, in addition, the absence of the need to apply large forces to the flaps 1 does not require the use various auxiliary means requiring additional operations for the installation and use of such means, for example, levers, crowbars, winches, jacks.

Thus, the proposed utility model makes it possible to increase the convenience, safety and efficiency of using the sliding door of the covered freight car body.
