Description

The utility model relates to the body structure of a covered wagon intended for the carriage of bulk cargo, the unloading of which is carried out through unloading hatches.

A boxcar body is known, containing walls with sheathing, racks, through holes are made in the upper part of the walls in the sheathing to eliminate vacuum when unloading the boxcar body (RU 197166, B61D 3/00, B61D 17/00, publ. 04/08/2020 (prototype )).

The technical problem characteristic of this device is the low operational efficiency due to the direct connection of the internal cavity of the body with the atmosphere through the holes in the walls of the body, leading to the possibility of unwanted atmospheric inclusions in the form of rain, snow, dust through these holes, which adversely affects as transported goods, such as grain, cement.

The technical result of the proposed utility model is to increase the operational efficiency of the use of the boxcar body, obtained by preventing foreign atmospheric inclusions from entering the internal cavity of the body.

This result is achieved by a box car body containing walls with sheathing, racks, through holes are made in the upper part of the walls to eliminate vacuum when unloading the box car body, racks are made with a transverse profile forming a closed longitudinal internal cavity, through holes in the upper part of the walls are brought into the inner cavity of these racks, while the lower part of the racks is placed in the lower part of the body, for communication of the inner cavity of the racks with the atmosphere in the lower part of the racks, inlet ventilation holes are made;

the lower part of the racks can be placed in the lower part of the body;

racks can be made of a U-shaped profile fixed on the wall cladding;

racks can be made of a corner profile, fixed with its longitudinal edges on the wall cladding;

through holes in the upper part of the walls can be equipped with protective U-shaped pads;

racks in their upper part can be covered with end caps;

the ends of the lower parts of the racks can be docked with the transverse beams of the body;

through holes in the skin to eliminate the vacuum can be made in the form of vertical grooves.

The claimed utility model is characterized in that the struts are made with a transverse profile forming a closed longitudinal internal cavity, through holes in the upper part of the walls are led into the internal cavity of these struts, while the lower part of the struts is located in the lower part of the body, to communicate the internal cavity of the struts with the atmosphere inlet ventilation openings are made in the lower part of the racks;

the lower part of the racks is located in the lower part of the body;

the racks are made of a U-shaped profile fixed on the wall cladding;

the racks are made of an angle profile, fixed with its longitudinal edges on the wall cladding;

through holes in the upper part of the walls are equipped with protective U-shaped pads;

racks in their upper part are covered with end caps;

the ends of the lower parts of the racks are docked with the transverse beams of the body;

through holes in the casing to eliminate the vacuum are made in the form of vertical grooves.

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

The body 1 of the covered wagon contains walls 2 with sheathing 3 and racks 4 having vertical sections G and inclined sections D (Fig. 1, 2, 5). In the upper part of the walls 2 in the casing 3, through holes 5 are made, for example, in the form of vertical grooves (Fig. 3, 4). Racks 4 are made with a transverse profile, forming together with the casing 3 a closed longitudinal internal cavity 4.1 (Fig. 5, 8, 9). Through holes 5 are made at the locations of the racks 4 and are aligned with a closed longitudinal internal cavity 4.1 racks 4. The lower part 4.2 racks 4 can be placed in the lower part of the body 1. In the lower part 4.2 racks 4, in inclined sections D, inlet through holes are made 4.3, designed to communicate a closed longitudinal internal cavity 4.1 of the pillars 4 with the atmosphere directly under the body 1 (Fig. 6). The inlet through holes 4.3 are mainly made in the side walls of the racks 4. This allows for the docking of the lower parts 4.2 of the racks with the transverse beams 7 of the body 1, which helps to maintain the strength of the structure, which, in turn, increases the operational efficiency of using the covered wagon body.

Through holes 5 in the upper part of the walls 2 can be equipped with protective U-shaped pads 6 fixed on the inner side of the walls 2. The presence of such protective U-shaped pads 6 allows for additional protection of the closed longitudinal internal cavity 4.1 of the racks 4 from direct ingress of loose cargo through through holes 5.

To cover the closed longitudinal internal cavity 4.1 on top of the rack 4 in its upper part can be equipped with end caps 4.4 (Fig. 7), or the upper part of the racks 4 can be docked with the beams of the body 1, with the upper trim of the body 1 (not shown). This will prevent the ingress of atmospheric inclusions through the upper part of the rack 4. To cover the closed longitudinal inner cavity 4.1 from below, the ends of the lower parts 4.2 of the racks 4 can be docked with the transverse beams 7 of the body 1, or closed with end caps (not shown).

Racks 4 can be made of a U-shaped profile, fixed with its longitudinal edges on the skin 3 of the walls 2 (Fig. 8), or from an angled profile, fixed with its longitudinal edges on the skin 3 of the walls 2 (Fig. 9), forming a closed longitudinal internal cavity 4.1 together with casing 3.

The utility model is used as follows.

When unloading the body 1 of a covered wagon through the unloading hatches 8 in the internal cavity of the body 1, reduced air pressure can form, preventing the rapid outflow of bulk cargo. To compensate for the resulting vacuum and equalize the air pressure in the internal cavity of the body 1 with the external atmospheric pressure in the upper part of the walls 2 of the body 1, through compensating holes 5 are made. contamination of the transported bulk cargo and the internal cavity of the body 1.

To reduce the probability of ingress or complete exclusion of unwanted atmospheric inclusions into the internal cavity of the body 1, through holes 5 are led into a closed longitudinal internal cavity 4.1 of the pillars 4. To communicate the closed longitudinal inner cavity 4.1 with the atmosphere, inlet through holes 4.3 are made in the lower part 4.2 of the pillars 4.

When unloading the body 1, atmospheric air enters the place freed from the load through the inlet ventilation openings 4.3 and enters the closed longitudinal internal cavity 4.1 of the pillars 4, moving up through which it enters through the through holes 5 into the internal cavity of the body 1, thereby equalizing the pressure difference in the internal body cavity 1 and external atmospheric pressure.

During the passage of atmospheric air through a closed longitudinal internal cavity 4.1 from the inlet ventilation holes 4.3 to through vertical grooves 5 and its entry into the internal cavity of the body 1, moisture condenses on the walls of the closed longitudinal internal cavity 4.1 - in the case of humid atmospheric air, or dust is deposited - if it is present in the atmosphere. When large polluting fractions, such as sand, various inclusions, enter the closed longitudinal internal cavity 4.1, they, not being able to climb up the vertical sections G of the racks 4, settle in inclined sections D, from where, when the covered wagon moves, they are removed through the inlet ventilation holes 4.3.

The implementation of the inlet ventilation holes 4.3 in the lower part 4.2 of the racks 4, which are located in the lower part of the body 1, directly under the body 1, serves as additional protection against vertical precipitation in the form of rain, snow, dust.

Thus, the use of the proposed structure of the box car body 1, in which the through holes 5 made in the upper part of the walls 2, are connected with the atmosphere through the inlet through holes 4.3 in the racks 4 and the closed longitudinal internal cavity 4.1 of the racks 4, which makes it possible to exclude entry into the internal cavity body 1 of unwanted atmospheric inclusions, which increases the operational efficiency of using the box car body.
