Description

The utility model relates to railway transport and can be used in the construction of an articulated flat car.

Known wagon-platform articulated type, containing interconnected by the articulation of cargo sections with bearing frames with flooring, installed on the undercarriage, the articulation unit is made with the possibility of placing above it pivotally mounted on the frame protective elements, see RU 180920, B61D 3/10 , B61D 17/06, publ. 06/29/2018 (prototype).

The technical problem inherent in this platform car is low reliability due to possible jamming and fracture of mutually overlapping protective elements in the form of transverse sides installed above the articulation unit, when the platform car passes curved sections of the track, in the event of uneven loading of sections of the articulated platform car occupying different vertical heights and leading to possible undesirable contact of the transverse sides.

The technical result of the proposed utility model is to increase the reliability of an articulated flat car.

The claimed technical result is achieved by a platform car containing cargo sections interconnected by an articulation unit with supporting frames mounted on undercarriages, the articulation unit is covered from above with protective elements, the protective elements are made in the form of rotary support screens pivotally mounted on the frame of one of the cargo sections, at the same time on the second cargo section there are support elements used to support the rotary support screens on them when they are rotated and placed above the articulation between the cargo sections;

- protective elements can be made of one central and two side rotary supporting screens;

- hinges of rotary supporting screens and supporting elements are installed on the corresponding cantilever frame ledges placed between the cargo sections.

- supporting elements can be made in the form of flat plates fixed at the same level with the flooring of the cargo sections;

- on the end edge of the central rotary screen, side bevels can be made, the lateral outer edges of the side rotary screens can also be made with bevels;

- rotary support screens can be made with a thickness of 3 to 8 mm;

- support elements can be made of wear-resistant material.

The claimed utility model differs from the prototype in that the protective elements are made in the form of swivel support screens pivotally mounted on the frame of one of the cargo sections, while the second cargo section has support elements used to support the swivel support screens on them when they are rotated and placed above the joint between the cargo sections;

- protective elements are made of one central and two side rotary supporting screens;

- hinges of rotary supporting screens and supporting elements are installed on the corresponding cantilever frame ledges placed between the cargo sections.

- supporting elements are made in the form of flat plates fixed at the same level with the flooring of the cargo sections;

- rotary support screens are made with a thickness of 3 to 8 mm;

- support elements are made of wear-resistant material.

Such differences give grounds to assert that the proposed technical solution complies with the criterion of patentability of a utility model - "novelty".

The utility model is shown in the drawings, where:

- in Fig. 1 - articulated platform car, general view;

- in Fig. 2 - articulation unit of cargo sections, top view, flooring of load-bearing frames is conventionally not shown, local view;

- in Fig. 3 - the same, isometric projection;

- in Fig. 4 - the same, the central rotary screen is conditionally not shown, isometric projection.

An articulated platform car comprises cargo sections 2, 3 interconnected by an articulation unit 1 (Fig. 1) with load-bearing frames 2.1, 3.1 (Fig. 2) with flooring 4. The cargo sections 2, 3 are mounted on undercarriages. The articulation unit 1 of the cargo sections 2, 3 is made with protective elements placed above it. The protective elements are made in the form of one central rotary support screen 7 and two side rotary support screens 8 (Fig. 3, 4). The rotary support screens 7, 8 are pivotally mounted with their hinges 7.1, 8.1 on the frame 3.1 of one of the cargo sections, for example, on the cargo section 3. To support the rotary support screens 7, 8, support elements are installed on the second cargo section 2, which can be made in the form of flat plates 9, fixed at the same level with the flooring 4 of the cargo sections 2, 3.

Hinges 7.1, 8.1 and supporting elements in the form of flat plates 9 can be installed on the corresponding cantilever frame protrusions 2.2, 3.2, placed in the free space between the cargo sections 2, 3, as well as on the body of the articulation unit 1. These protrusions, being the most durable and rigid supporting elements, capable of absorbing vertical forces from heavy loads moving along the rotary support screens 7, 8, for example, wheeled or tracked vehicles, which positively affects the reliability of the articulated platform car.

Side bevels 7.2 can be made on the end edge of the central rotary screen 7. The lateral outer edges of the side swivel support screens 8 can also be made with bevels 8.2, excluding the presence of sharp external corners on the swivel support screens 8. In combination with the side bevels 7.2 of the central swivel support screen 7, the bevels 8.2 form a single safe line of the edge of the swivel support screens 7, 8, which simplifies their use, eliminates emergency situations.

Rotary support screens 7, 8 can be made of a metal sheet with a thickness of 3 to 8 mm. At the same time, the implementation of rotary support screens 7, 8 with a thickness of less than 3 mm does not provide the necessary strength, the implementation of a thickness of more than 8 mm unreasonably increases their weight. Support elements in the form of flat plates can be made of wear-resistant material, such as hardened steel, which ensures their longer service life.

The utility model is used as follows.

The articulated platform car is designed to carry various cargoes. Protective elements made in the form of pivoting support screens 7, 8 make it possible to protect the articulation unit 1 from falling on it of various heavy load elements that can render it inoperable. In addition, the articulated flatcar allows the transportation of various wheeled and tracked vehicles that can be loaded onto the flatcar under their own power while moving along the flatcar from one cargo section to another.

In this case, to pass the free space between the cargo sections 2, 3 directly above the articulation unit 1, rotary support screens 7, 8 are used. 8.1, lowering onto the support elements made in the form of flat plates 9, fixed at the same level with the flooring 4 of the cargo sections 2, 3. As a result, the free space between the cargo sections 2 and 3 is blocked and it becomes possible for self-propelled vehicles to pass through the rotary support screens 7, 8 with protection of articulation 1.

When an articulated type car passes the proposed design of the radius sections of the rail track, the rotary support screens 7, 8 slide freely on flat plates 9 of the support elements, without creating bending forces both in the rotary support screens 7, 8 themselves and in their hinges 7.1, 8.1 , which increases the reliability of the articulated platform car.

The implementation of protective elements in the form of several rotary support screens 7, 8 allows them to be made less heavy and capable of being used by one operator.
