Description

The utility model refers to the rolling stock of railway transport and can be used in the construction of covered freight cars, namely, as a device for fixing the sliding doors of covered freight cars in an intermediate position.

From the prior art, the design of a locking device for a sliding door of a covered freight car is known (Patent RU 2415040 IPC B61D 19/00, E05B 65/14, publ. 03/27/2011), including a filler with a tooth located on the wall of the car with the ability to rotate around the axis , perpendicular to the plane of movement of the carriage door, the refusal tooth is designed to interact with the bracket rigidly fixed to the door. This technical solution is aimed at ensuring increased reliability of door locking and ensuring control over unauthorized access to the car.

The disadvantage of this design of the locking device is that it is aimed at fixing the sliding doors in a fully closed position, the use of this design for fixing the doors in an intermediate position is impractical, since the placement of this structure on the side wall of the car from the outside along the movement of the sliding doors will increase the gap between the side wall and the door, as well as the complexity of installation of the structure, an increase in labor intensity during use.

The closest analogue (prototype) to the claimed utility model is the structure of a freight car containing a doorway, door pillars, a sliding door having a flap and installed next to the doorway with the possibility of longitudinal movement between two extreme positions, a locking device containing a flap element mounted on the door a rack and a fixing element installed on the sliding door leaf, containing a groove made with the possibility of fixing the zakidny element (see patent RU No. 177636 IPC B61D 19/00, B61D 3/00 publ. 03/02/2018).

The disadvantage of the prototype is the complexity of the manufacture of the back and fixing elements and the complexity of the installation, which requires high precision in the coordination of their mutual arrangement.

The technical result of the utility model is to simplify the design of the fixing device and the fixing element due to the simplicity of manufacturing the parts included in their composition, as well as due to their relative position.

The technical result is achieved in that the covered freight car contains a doorway, door posts, a sliding door consisting of leaves and installed next to the doorway with the possibility of longitudinal movement of the leaves between two extreme positions, and a device for fixing the open door leaf in an intermediate position, consisting of a flap element mounted on a door post with the ability to rotate around an axis, and a fixing element installed on the inner side of the sash, and the sashes on the inner side contain a sheathing made of corrugated sheet, and the fixing element is two strips installed in parallel in the corrugation of the sheet on the distance S, ranging from 10 to 60 mm from each other, for the location of the backing element between them.

The essence of the utility model is illustrated by drawings, where Fig. 1 shows a general view of a covered freight car; Fig. 2 is a view from the inside of the car at the doorway, with the half-open door fixed, FIG. 3 - section E-E of Fig. 2, FIG. 4 - section b-b Fig. 3, FIG. 5 - section C-C of Fig. 4.

The covered freight car contains a body 1, consisting of a roof 2, end walls 3, frame 4, side walls 5. (Fig. 1). Each side wall 5 contains a doorway 6, on the sides of the doorway 6 there are racks 7. On the side wall 5 of the covered freight car for loading and unloading, sliding doors 8 are installed, consisting of two flaps 9 (Fig. 2). Each sash 9 has the ability to move longitudinally along the side wall 5 between two extreme positions:

the closed doorway in FIG. 1 (doors 9 are closed) for transporting cargo and moving the wagon,

an open doorway (the doors 9 are spread apart on the side wall (not shown)) for loading and unloading operations.

To fix the open sash 9 in an intermediate position on the post 7 of the doorway 6 there is a fixation device 10, consisting of a channel 11 with coaxial holes 12 made in its side shelves. An axis 13 is pivotally installed in the holes 12, on which a limiter 14 is rigidly fixed between the shelves of the channel 11, and a collar element 15 is rigidly fixed on the side of the door opening (Figs. 4, 5).

The flap 9 on the inner side contains a skin 16 made of corrugated metal sheets. On the casing 16 there is a fixing element 17, which is two strips 18 (Fig. 2) located inside the corrugation parallel to each other.

The strips 18 are rigidly fixed to the sheathing 16 at a distance S from 10 to 60 mm from each other. The choice of the range of the specified distance is due to the need and sufficiency of the location of the overhead element 15 in this gap. With a decrease in this value, jamming of the overhead element 15 between the slats 18 during operation may occur, an increase in size over 60 mm will inevitably lead to an unreasonably large free movement of the sash in a fixed position which can lead to an emergency during work.

The number of fixing elements can be from 2 to 10, depending on the required accuracy of the sash position during work.

The principle of operation of the device for fixing sliding doors of a covered freight car in an intermediate position:

Non-working position

In the inoperative position, the locking device is located during transportation of the wagon (doors are closed), or for performing work inside the freight wagon with fully open sliding doors (doors are open in the extreme position, for example, during loading and unloading operations).

In this position, the cover element 15 is directed towards the inside of the car, the movement limiter 14 resting against the rack 7 keeps the cover element 15 in an inoperative position (see Fig. 3 - the position indicated by the dash-dot line). The leaf 9 of the sliding door 8 moves freely along the side wall.

Working position

It is used when it is necessary to fix the sash in an intermediate position (for inspecting the car, during loading and unloading operations, etc.).

When opening, the flap 9 is brought to a position where the locking element 17 is opposite the flap element 15. To fix the sliding door 8 in an intermediate position, the flap element 15 is turned clockwise on the axis 12. In this case, the flap element 15 is placed between the slats 18 - a fixing device brought into working position (see Fig. 3 - the position indicated by the solid line). The leaf 9 is fixed in an intermediate position.

The transfer to the inoperative position is carried out in the reverse order.

The parts included in the design of the fixing device and fixing elements of the proposed technical solution are easy to manufacture and assemble together, while the proposed version indicates the positioning of the fixing device on the door post, and the fixing element on the door leaf so that it allows installation (installation) of the device fixing and fixing element at the stage of assembling the specified units of the car, and not to install and adjust relative to the fixing element after assembling the car as a whole, as in the specified prototype. That, in general, simplifies the design and leads to a decrease in labor intensity during assembly.
