Description

The inventive utility model relates to railway transport, in particular to the design of the sliding doors of a covered wagon.

Known sliding door of the vehicle, containing the upper and lower mounting elements in the form of support and guide rollers interacting with rectilinear guides, with which the shutter doors are movably mounted in the back of a covered wagon, and.with. USSR No. 835865 B61D 19/00, publ. 06/07/1981.

A technical problem inherent in this device is its low reliability due to the use of a guide support as a guide and holding element, mounted on the car body, subject to constant static and dynamic effects from the weight of the sliding wings, and not equipped with additional guiding elements that prevent jamming the sash when moving it to open or close the sliding door.

A roller suspension of a door of a covered wagon is also known, containing upper and lower mounting elements in the form of support and guide rollers, with the help of which the sliding door flaps are movably mounted in rectilinear rails fixed on the body of a covered wagon, Russian patent No. 2274569, B61D 19/00, publ. . 10.27.2005 (prototype).

This technical solution also has low reliability, due to the use as a guide and holding top element in the form of a straight guide, which is under constant load of the full weight of the sliding door leaves and is subject to constant exposure to static and dynamic loads during operation of the covered wagon, in addition, the absence of additional guides elements in the lower part of the leaflets leads to skewing and jamming of the leaflets when they are moved to open or close ytiya sliding door.

The technical result of the claimed utility model is to increase the reliability of the roller suspension of the sliding door of the covered wagon.

The specified technical result is achieved by roller suspension of a sliding door of a covered wagon, containing upper and lower mounting elements in the form of support and guide rollers, with which the sliding door flaps are movably mounted in straight guides mounted on the body of a covered wagon, the guide rollers of the upper mounting elements are vertically fixed with axes in the upper part of the wings and are placed inside the upper straight guide, made in the form of a guide profile with vertical with the shelves pointing downward, the lower mounting elements are made in the form of support rollers with axes horizontally fixed in the lower part of the sliding door leaf and resting on the lower straight guide, while the said lower straight guide is additionally covered by guide rollers from the sides opposite to their sides, vertically fixed by their axes on opposite sides of the sliding door leaf; the top straight guide can be made of channel; the upper straight guide can be made of a trough-shaped profile; a protective visor can be fixed above the upper straight guide on the body of a covered wagon; above the rollers of the lower mounting elements on the flaps of the sliding door, protective visors can be fixed on the outside of the covered wagon; the lower straight guide can be fixed on the supporting brackets mounted on the body of the covered wagon.

The inventive utility model differs from the prototype in that the guide rollers of the upper mounting elements are vertically fixed by their axes in the upper part of the wings and placed inside the upper straight guide, made in the form of a guide profile with vertical shelves pointing down, the upper straight guide is fixed to the body of the covered wagon, the lower mounting elements are made in the form of support rollers with axes horizontally fixed in the lower part of the shutter door leafs and resting on neither nyuyu straight guide, said lower straight guide is further covered with the side opposite its side guide rollers, fastened vertically with their axes at opposite sides of the wings of the sliding door; the upper straight guide can be made of channel; the upper straight guide can also be made of a trough-like profile; a protective visor is fixed above the upper straight guide on the body of a covered wagon; protective rollers are fixed above the rollers of the lower mounting elements on the shutters of the sliding door from the outside of the covered wagon; the lower straight guide is mounted on the supporting brackets mounted on the body of the covered wagon. Such differences from the prototype give reason to assert that the proposed technical solution meets the patentability criterion of a utility model - “novelty”.

The inventive utility model is presented in the images, where:

- in FIG. 1 shows a part of the side wall of the body of a covered wagon with a sliding door with one of the wings, which is shown in the open position;

- in FIG. 2 - remote element A from FIG. one;

- in FIG. 3 - section B - B in FIG. one;

- in FIG. 4 - section B - B in FIG. 2;

- in FIG. 5 is a partial view of the lower mounting elements, a protective casing is conventionally not shown, isometric view;

- in FIG. 6 - the same, inside view of a covered wagon, isometric view.

The roller suspension of the sliding door 1 (Fig. 1, 2) of the covered carriage 2 contains upper mounting elements 3 and lower mounting elements 4, with which the flaps 1.1 of the sliding door 1 are movably mounted on the side walls of the body of the covered car 2. The upper mounting elements 3 (Fig. .3) contain guide rollers 3.1 vertically fixed by their axles 3.2 in the upper part of the wings 1.1. The guide rollers 3.1 are placed inside the upper straight guide 3.3, made in the form of a trough-like profile with vertical shelves 3.4, directed downward. As such a trough-like profile, a channel, rigidly connected corners (not shown) can be used. The lower mounting elements 4 are made in the form of support rollers 4.1 (Fig. 4) with axles 4.2 horizontally mounted at the bottom of the leaves 1.1 of the sliding door 1. The support rollers 4.1 are supported by a lower straight guide 4.3, which is mounted on supporting brackets 4.4 mounted on the body a boxcar, for example, on a longitudinal side beam 2.1. To guide the support rollers 4.1 along a straight guide 4.3, said guide 4.3 is swept from the lateral opposite sides by guide rollers 4.5. Guide rollers 4.5 are vertically fixed with their own axles 4.6 on opposite sides of the sash 1.1.

As a protection against environmental influences on the elements of the roller suspension of the sliding door of the covered wagon, a protective visor 3.5 can be fixed on the upper straight guide 3.3. Similar protective visors 4.7 can also be installed above the rollers 4.5 of the lower mounting elements 4 on the wings 1.1 of the sliding door 1 from the outside of the covered carriage 2.

The technical result of the claimed utility model, which consists in increasing the reliability of the roller suspension of a sliding door of a covered wagon, is achieved as follows.

To open and close the sliding door 1, the sash 1.1 is moved along the lower straight guide 4.3. In this case, the support rollers 4.1 roll along the upper surface of the lower straight guide rail 4.3. The sash 1.1 and the support rollers 4.1 are oriented on the specified straight guide 4.3 using the side guide rollers 4.5, fixed with their axes 4.6 on the opposite sides of the sash 1.1 of the sliding door 1 and covering the straight guide 4.3 on both sides. The lower straight guide 4.3 is fixed to the supporting brackets 4.4. The holding and direction of the upper part of the flaps 1.1 is carried out by guide rollers 3.1, of the upper mounting elements 3, located inside the profile of the upper rectilinear guide 3.3, made in the form of a trough-like profile with downward directed vertical shelves 3.4. The use of support brackets 4.4, which are not limited in size, for fixing the lower guide 4.3, allows the support brackets 4.4 to be made of the necessary strength and stiffness, and to securely fix the lower guide 4.3 on the body of a covered wagon. The presence of guide rollers 4.5 in the lower mounting elements, vertically fixed by their axles 4.6 on opposite sides of the sash 1.1, allows the sash 1.1 to be guided reliably along the lower guide 4.3.

Thus, the proposed design of the roller suspension of the sliding door allows you to transfer the effect of the weight of the wings from the upper straight guide 3.3 to the lower straight guide 4.4, thereby unloading the fastening nodes of the upper straight guide 3.3. The use of protective visors 3.5 and 4.7 allows you to protect the upper and lower mounting elements from the effects of the external environment. The guide rollers 4.5 exclude the skewing and jamming of the movable flaps 1.1 when opening or closing the sliding door 1.
