Description

The proposed technical solution relates to railway transport, namely to the means of fastening the air ducts of the brake system of a railway vehicle.

Known attachment point of the main air line and the air supply line of the brake system of a railway vehicle, containing mounting brackets mounted on the frame of the car, on which the air lines of the brake system are mounted, see EN 192238, B60T 13/24, B60T 17/04, F16L 3/22, publ. 09.09. 2019 (prototype).

The technical problem inherent in this device is its low operational reliability, caused by the possibility of mutual contact during the movement of a railway vehicle with freely placed sections of the air ducts of the brake system, leading to their premature mutual wear and to the inoperability of the brake system of the railway vehicle.

The technical result of the proposed utility model is to increase the operational reliability of the air duct attachment of the brake system of a railway vehicle.

The specified technical result is achieved by the mount of the air ducts of the brake system of a railway vehicle, containing the mounting brackets installed on the frame of the car, on which the air ducts of the brake system are mounted, the sections of the air ducts of the brake system, freely placed in the space between the mounting brackets, are interconnected by retaining strips made with guide holes through which the specified sections of the air ducts are passed, and the center dimensions of the guide holes are made with a value that excludes mutual contact of the sections of the air ducts passed through the guide holes when the railway vehicle is moving;

- retaining straps can be placed between the walls of the car frame beams and elements of pipeline fittings of air ducts of the brake system (couplings, locknuts);

- sections of air ducts passed through through holes in the transverse frame elements can be interconnected by retaining strips installed on both sides of the said transverse frame elements;

- retaining straps can be made of non-metallic materials;

- retaining straps can be placed on the flexible sections of the brake line air ducts in the inter-car space.

The claimed utility model differs from the prototype in that the sections of the air ducts of the brake system, freely placed in the space between the mounting brackets, are interconnected by retaining strips made with guide holes through which the indicated sections of the air ducts are passed, and the center dimensions of the guide holes are made with a value that excludes mutual touching the sections of air ducts passed through the guide holes during the movement of the railway vehicle;

- retaining straps are placed between the walls of the car frame beams and elements of pipeline fittings of the brake system air ducts (couplings, locknuts);

- sections of the air ducts, passed through through holes in the transverse frame elements, are interconnected by retaining strips installed on both sides of the indicated transverse frame elements;

- retaining bars are made of non-metallic materials;

- the retaining straps are placed on the flexible sections of the brake line air ducts in the inter-car space.

Such differences from the prototype give reason to assert that the proposed technical solution meets the criterion of patentability of a utility model - "novelty".

The utility model is shown in the drawings, where:

- in Fig. 1 - mount of the air ducts of the brake system of a railway vehicle, top view;

- in Fig. 2 - the same, local view, isometric projection;

- in Fig. 3 - remote element "A" from Fig. 2, isometric view;

- in Fig. 4 - sections of air ducts passed through through holes in the transverse elements of the frame of the railway vehicle, local view, isometric projection.

The mount of the air ducts of the brake system of a railway vehicle contains mounting brackets 1 (Fig. 1, 2) mounted on the frame 2 of the car. Air ducts 3 of the brake system of the railway vehicle are mounted on the mounting brackets 1.

Sections of the air ducts 3 of the brake system of a railway vehicle, freely placed in the spaces between the mounting brackets 1, are interconnected by retaining straps 4. The retaining straps 4 are made with guide holes 4.1, through which the indicated sections of the air ducts 3 are passed. The interaxial dimensions of the guide holes 4.1 are made by the value excluding mutual contact of the sections of the air ducts 3 passed through the guide holes 4.1 during the movement of the railway vehicle.

The retaining bars 4 can be placed between the walls of the beams 5 (Fig. 3) of the car frame and the elements 6 of the pipe fittings of the air ducts of the brake system, made in the form of couplings, nuts, locknuts.

Sections of the air ducts 3, passed through through holes 5.1 (Fig. 4) in the transverse elements of the frame beams 5, can also be interconnected by retaining strips 4 installed on both sides of the transverse elements of the beams 5 of the frame, end beams can be used as such beams , transverse beams, pivot beams.

The retaining bars 4 can be made of non-metallic materials.

Retaining strips 4 can be placed on the flexible sections 3.1 of the air ducts 3 of the brake line in the inter-car space.

The increase in operational reliability, which is the technical result of the proposed utility model, is achieved as follows.

During the movement of railway transport, the air ducts of the brake line are subjected to dynamic spatial influences, vibration, bending of the air ducts, and the occurrence of internal stresses at the points of fastening of the air ducts. In the case of mutual contact of the air ducts, their mutual wear is sharply accelerated with the possibility of leakage of compressed air, which ultimately leads to the failure of the brake system of the railway vehicle.

To exclude mutual contact between sections of the air ducts 3 of the brake system of a railway vehicle, they are spatially interconnected with the help of retaining bars 4. To do this, sections of the air ducts 3 are passed through guide holes 4.1 made in the retaining bars 4. The interaxial dimensions between the guide holes 4.1 are performed with a value sufficient to exclude mutual contact of sections of the air ducts 3 during the movement of the railway vehicle.

To fix the retaining bars 4 on selected sections of the air ducts 3, the retaining bars 4 can be placed between the walls of the beams 5 of the car frame and elements 6 of the pipeline fittings of the brake system air ducts, such as couplings, nuts, locknuts, or can be installed on both sides of any transverse elements of the beams 5 frame, such as end beams, cross beams, pivot beams or throughout the air ducts where needed. Also, the retaining straps 4 can be placed on the flexible sections 3.1 of the air ducts 3 of the brake line in the inter-car space, which eliminates the mutual contact of the flexible sections when the railway vehicle passes curved sections of the rail track of small radius.

Thus, the use of retaining bars 4, placed on freely suspended sections of the air ducts 3, excludes their mutual contact, reduces contact with the frame elements 2 of the car, eliminates breaks, bends, reduces internal mechanical stresses in the air duct attachment points 3, which increases the operational reliability of the air duct attachment point braking system of a railway vehicle.
