Description

The utility model relates to the design of freight car bodies and allows for the dismantling of running bogies in conditions of non-depot repair and maintenance of freight cars, for example, in emergency situations.

Known freight car containing a body with side and end walls with vertical racks, lower body harness, the body is mounted on undercarriages connected in series by the articulation unit, the body is made with a lowering of the floor between the undercarriages, formed in the form of a hopper with a bottom and side walls, bottoms bunkers are equipped with lower transverse beams, the side walls of the bunkers are reinforced with side stiffeners, see EN 183059, B61D 3/10, publ. 09/07/2018 (prototype).

The technical problem inherent in this freight car is the impossibility of dismantling the common middle undercarriage on railway tracks, for example, in emergency conditions, due to the lack of external thrust elements on the freight car body to interact with mobile lifting jacks used to raise the middle part of the connected knot articulation of bodies when releasing a common middle undercarriage.

The technical result of the proposed utility model is to increase the efficiency of the use of a freight car while improving the safety of railway traffic.

The claimed technical result is achieved by a freight car containing bodies with side and end walls with vertical posts, lower body trim, bodies mounted on undercarriages and connected in series by an articulation unit, bodies are made with a lowering of the floor between the undercarriages, formed in the form of a bunker with a bottom and side walls, the bottoms of the bunkers are equipped with lower transverse beams, the side walls of the bunkers are reinforced with side stiffeners, on the side of the joint between the side stiffeners of the bunkers, thrust beams are rigidly fixed in a horizontal position, designed to interact with lifting jacks when lifting bodies:

the bodies can be mounted on three running bogies, with the bodies resting on one common middle bogie;

thrust beams can be made of an angle profile;

thrust beams can be fixed with their ends on the side stiffeners of the bunkers;

thrust beams can be fixed with their longitudinal edges on the surface of the casing of the side walls of the bunkers;

thrust beams in their inner cavity can be provided with transverse stiffeners;

the ends of the thrust beams can be made with cutouts that repeat the transverse profile of the side stiffeners of the bunkers, with these cutouts the thrust beams are joined and rigidly connected to the side stiffeners of the bunkers;

the side racks of the rigidity of the bunkers can be rigidly joined by their upper ends with the lower body trim;

the side stiffeners of the side walls of the hoppers can be connected with their lower ends to the lower transverse beams, the upper ones - to the vertical posts of the side walls of the body.

The claimed utility model differs from the prototype in that on the side of the joint between the side stiffeners of the hoppers, thrust beams are rigidly fixed in a horizontal position, designed to interact with lifting jacks when lifting bodies;

the bodies are mounted on three running bogies, with the bodies resting on one common middle bogie;

thrust beams are made of an angle profile;

thrust beams are fixed with their ends on the side stiffeners of the bunkers;

thrust beams are fixed with their longitudinal edges on the surface of the casing of the side walls of the bunkers;

thrust beams in their inner cavity are provided with transverse stiffeners;

the ends of the thrust beams are made with cutouts that repeat the transverse profile of the side stiffeners of the bunkers, with these cutouts the thrust beams are docked and rigidly connected to the side stiffeners of the bunkers

the side racks of the rigidity of the bunkers are rigidly connected by their upper ends to the lower trim of the body;

the side stiffeners of the side walls of the hoppers are connected by their lower ends to the lower transverse beams, the upper ones - to the vertical posts of the side walls of the body.

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

in fig. 1 - freight car, general view;

in fig. 8 is the same, isometric view.

The freight car contains a body 1 (Fig. 1) with side walls 2, end walls 3. These walls 2, 3 contain vertical racks 4, the lower trim 5. The body 1 is installed on the undercarriage 6 and connected in series with the articulation unit 7. Each of the bodies 1 is made with a lowering of the floor between the undercarriages, formed in the form of a hopper 8 (Fig. 2) with a bottom 8.1 and side walls 8.2. The bottoms 8.1 of the hoppers 8 are reinforced with lower transverse beams 8.3. The side walls 8.2 of the hoppers 8 are equipped with side stiffeners 8.4 (Fig. 3-6).

The side racks of stiffness 8.4 of the bins 8 can be rigidly connected with their lower ends to the lower transverse beams 8.3, their upper ends - with vertical racks 4 of the side walls 2 of the body 1 or with the lower trim 5 of the body 1.

On the side of the articulation unit 7 between the side stiffeners 8.4 of the hoppers 8, thrust beams 9 are rigidly fixed in a horizontal position, designed to interact with the lifting jacks 10 when lifting the bodies 1.

Bodies 1 can be mounted on three undercarriages 6, with both of the bodies 1 resting on one common middle bogie 6.1.

The thrust beams 9 can be made of an angled profile, fixed at the ends on the side stiffeners 8.4 of the hoppers 8. Additionally, the thrust beams 9 can be fixed with their longitudinal edges on the surface of the skin of the side walls 8.2 of the bins 8.

The thrust beams 9 in their inner cavity can be provided with transverse stiffeners 9.1 to increase their strength and rigidity.

The ends of the thrust beams 9 can be made with cutouts 9.2, repeating the transverse profile of the side stiffeners 8.4 of the bins 8. Cutouts 9.2 of the thrust beams 9 are docked and rigidly connected to the side stiffeners 8.4 of the bins 8.

The utility model is used as follows.

In the event of an emergency, for example, in the event of a malfunction of the 6.1 undercarriage that occurred when a freight car derailed, it becomes necessary to dismantle the 6.1 middle undercarriage, remove it from the track and install a new, serviceable bogie. To do this, it is necessary to disengage the articulation assembly 7 with the thrust bearing and kingpin of the middle undercarriage 6.1. Lifting the bodies 1 with the help of lifting jacks 10 by the pivot beams or body elements 1 in the area of the pivot sections, as is done in the normal mode during depot repairs, does not allow, under the operating conditions of a freight car, to remove the middle undercarriage 6.1 from under the bodies 1 in the transverse direction , since the lifting jacks 10 in this case will serve as an obstacle to the withdrawal of the middle undercarriage 6.1 from under the bodies 1 of the freight car.

To free up space for the withdrawal of the middle undercarriage 6.1 from under the bodies 1 of the freight car, lifting jacks 10 are located on the sides of the hoppers 8 (Fig. 7, 8) closer to the extreme undercarriages 6. To interact with the rods of the jacks 10 between the side stiffeners 8.4 bunkers 8 rigidly in a horizontal position fixed thrust beams 9.

The lifting jacks 10 are installed with their bases 10.1 on the ground or the ends of the sleepers, the rods of the lifting jacks 10 are placed under the thrust beams 9. After the lifting jacks 10 are put into operation, their rods, acting on the rigidly fixed thrust beams 9, raise the middle part of the articulated bodies 1, freeing the center plate articulation unit 7 from its articulation with the thrust bearing and kingpin of the middle undercarriage 6.1. The released medium undercarriage 6.1 is moved in the transverse direction by any technological means: winches, lifts, manipulators. A serviceable middle undercarriage 6.1 is installed on the vacant seat. The jacks 10 lower the articulated bodies 1, aligning the center plate of the articulation assembly 7 with the thrust bearing and pivot of the middle undercarriage 6.1. Lifting jacks 10 are removed from the track, after which the freight car is ready for further use.

Thus, the placement of horizontally rigidly fixed thrust beams 9 between the side stiffeners 8.4 of the bins 8 makes it possible to use them as stops for lifting jacks 10 installed so as not to be an obstacle to the transverse movement of the middle undercarriage 6.1, which increases the efficiency of using a freight car while improving the safety of railway traffic.
