Abstract

The utility model relates to tank cars. Installation and fastening between the bearing legs (4.1) of the reinforcing horizontal shelf (4.2) rigidly connects the bearing legs (4.1) of the boiler (1), forming a rigid box-shaped structure. Reinforcement of the longitudinal brackets (6) with stiffening ribs (8) prevents bending of the longitudinal brackets (6) due to the weight of the boiler (1). Flanging (4.3) on the edges of the reinforcing horizontal flange (4.2), which acts as an additional stiffener, also increases the strength and rigidity of the central support unit (4) and, as a result, the overall reliability of the railway tank car. 3 w.p. f-ly, 4 ill.

Description

The claimed utility model relates to rolling stock, in particular, to tank cars.

Known railway tank car, containing a boiler, mounted on a frame by means of end support units and a central support unit made in the form of bearing paws, fixed on the boiler, connected by fasteners with longitudinal brackets made in the form of a corner with an elongated horizontal shelf and a shortened vertical one, cantilevered with their horizontal shelves on the upper surface of the backbone beam, see RU 157804, B65D 5/06, publ. 12/10/2015 (prototype).

The technical problem typical for this technical solution is the low rigidity of the central support unit connecting the boiler with the center beam of the frame of the railway tank car, due to the non-rigid structure of the bearing legs fixed on the boiler of the tank car.

The technical result of the claimed utility model is to increase the reliability of the railway tank car by increasing the rigidity and strength of the central support unit.

The specified technical result is achieved by a railway tank car containing a boiler mounted on a frame by means of end support units and a central support unit made in the form of bearing legs fixed on the boiler, connected by fasteners with longitudinal brackets made in the form of a corner with an elongated horizontal shelf and shortened vertical, cantilevered with its horizontal shelves on the upper surface of the backbone beam, between the supporting legs of the boiler there is a reinforcing horizontal shelf that rigidly connects the supporting legs of the boiler, the longitudinal brackets are reinforced with stiffening ribs, butted and rigidly connected to the horizontal and vertical shelves and longitudinal shelves and rigidly fixed to the side walls of the backbone girder; the reinforcing horizontal shelf can be rigidly connected with its middle part to the boiler; reinforcing horizontal shelf, fixed between the supporting legs of the boiler, can be made with flanging along its edges; The stiffening ribs supporting the longitudinal brackets can be installed vertically and with an emphasis on the horizontal flange of the backbone beam.

The claimed utility model differs from the prototype in that a reinforcing horizontal shelf is fixed between the supporting legs of the boiler; spinal beams; the reinforcing horizontal shelf is rigidly connected by its middle part with the boiler; reinforcing horizontal shelf, fixed between the supporting legs of the boiler, is made with flanging along its edges; the stiffening ribs supporting the longitudinal brackets are installed vertically and with an emphasis on the horizontal flange of the backbone beam.

The utility model is represented by drawings, in which:

- in FIG. 1 - boiler of a railway tank car, fixed on the frame, the rest of the details are not shown conventionally;

- in FIG. 2 - section a-a in Fig. one;

- in FIG. 3 - reinforcing horizontal shelf of the central support unit, isometric projection;

- in FIG. 4 - central pivot point, local view, isometric projection.

The proposed railway tank car contains a boiler 1 (Fig. 1, 2), mounted on a frame 2 by means of end support units 3 and a central support unit 4. The central support unit 4 contains load-bearing legs 4.1, fixed on the boiler 1. The load-bearing legs 4.1 are connected by fastening elements 5 with longitudinal brackets 6. Longitudinal brackets 6 are made in the form of a corner with an elongated horizontal shelf 6.1 and a shortened vertical shelf 6.2. The longitudinal brackets 6 are cantilevered and longitudinally fixed with their horizontal shelves 6.1 on the upper surface 7.1 of the backbone 7. Between the supporting legs 4.1 of the boiler 1, a reinforcing horizontal shelf 4.2 (Fig. 3, 4) is fixed, rigidly connecting the supporting legs 4.1 of the boiler 1. In addition , reinforcing the horizontal shelf 4.2 with its middle part can be rigidly connected, for example, by welding with the boiler 1. Longitudinal brackets 6 are reinforced from below by ribs 8 of stiffness, rigidly fixed on the side walls 7.2 of the backbone 7, butted and rigidly connected to the horizontal shelves 6.1 and vertical shelves 6.2 longitudinal brackets 6.

Reinforcing horizontal shelf 4.2 can be made with 4.3 flange along its edges.

The ribs 8 of the stiffness, reinforcing the longitudinal brackets 6, can be installed vertically and with an emphasis on the horizontal flange 7.3 of the backbone 7.

The claimed technical result, which consists in increasing the reliability of the railway tank car by increasing the rigidity and strength of the central support unit 4, is provided as follows.

Installation and fastening between the supporting legs 4.1 of the boiler 1 of the reinforcing horizontal shelf 4.2 rigidly connects the supporting legs 4.1 of the boiler 1, forming a rigid box-like structure. Reinforcement of the longitudinal brackets 6 with ribs 8 of stiffness, rigidly connected to the horizontal shelves 6.1 and vertical shelves 6.2 of the longitudinal brackets 6 and fixed on the side walls 7.2 of the backbone 7 with an emphasis on the horizontal shelf 7.3 of the backbone 7, prevents bending of the longitudinal brackets 6 from the weight of the boiler 1 Execution of flanging 4.3 on the free transverse edge of the reinforcing horizontal flange 4.2, which acts as an additional stiffener, also provides an increase in the strength and rigidity of the central support unit 4.

An increase in the strength and rigidity of the central support unit 4 makes it possible to spread the bearing legs 4.1 to a much greater mutual distance in comparison with the prototype, in which the longitudinal brackets are not reinforced from below by stiffening ribs, similar to the stiffening ribs 8 in the proposed design. A wider spacing of the bearing legs 4.1 and the presence of a reinforcing horizontal shelf 4.2 between them ensures a more stable basing of the boiler 1 on the frame 2 of the railway tank car.

Thus, the proposed design of the central support unit 4 makes it possible to increase the reliability of the railway tank car by increasing the rigidity and strength of the central support unit 4 of the railway tank car.
