Description

The technical field to which the utility model relates.

This utility model relates to railway rolling stock, and in particular to the construction of hopper cars designed both for transporting grain and grinding products, as well as mineral fertilizers.

State of the art

A hopper car is a self-unloading bunker freight car for transporting bulk bulk cargo. The body has the shape of a funnel, in the lower part of which there are unloading hatches, when opened, the cargo falls out through them under its own weight, which contributes to quick unloading.

There are various technical solutions in this field.

For example, a hopper car model 19-752 is known (see the link http://vagons.com/vagon/986), in which a classic four-axle structure body is used, in which all hoppers with discharge necks are placed between the bogies.

A known patent of the Russian Federation for utility model No. 158610 (IPC B61D 7/00, B61D 17/08, B61D 17/12, publ. 01.20.2016). The hopper car according to this patent includes running gears, automatic coupler and brake equipment, a body consisting of a base in the form of a beam frame, side and end walls, bunkers with discharge hatches and a roof with loading hatches. The roof of the car is convex and curved, and the side walls of the hopper car are convex outward and curved in the cross section of the hopper car, and are associated with a convex curved roof.

Studies have shown that the most promising way to further improve the efficiency of freight transport is the use of articulated six-axle wagons.

Known articulated hopper cars designed for the transport of bulk cargo (US patent for the invention No. 4644871, IPC B61D 1/14, B61D 7/02, publ. 12/12/1985, Canadian patent for the invention No. 1233367, publ. 01.03.1988) . The construction of a well-known articulated hopper car includes one intermediate and two end carriages forming the carriage chassis, and two car sections, each of which has a separate body designed to accommodate the transported bulk cargo, and is connected to the adjacent section by an articulated joint unit. In this case, the car sections in the area of the articulation unit are supported through the articulation unit on one common intermediate carriage. The sections of the known hopper car contain discharge hoppers for unloading the transported cargo, which are located between the bogies, while the extreme end walls of the body sections are substantially inclined relative to the vertical, so as to ensure the direction of movement of the transported cargo to the discharge hoppers. A disadvantage of the known hopper car is the uneven distribution of the load on the carts of the hopper car, which leads to their increased wear and reduces the overhaul interval. In addition, sections of the known hopper car have a small volume, due to the location of the end walls with a large deviation from the vertical.

Known articulated hopper car according to the patent of the Russian Federation for utility model No. 149541 (IPC B61D 7/00, publ. 01/10/2015), which, as the closest in combination of essential features, was adopted as a prototype. Known hopper car contains a running gear and a body, which is mounted on the running gear and contains at least two successively arranged sections for receiving cargo, with each section of the body containing discharge bins for unloading the transported cargo, and the running gear contains at least three trolleys moreover, each section of the body rests on two carts, and adjacent sections of the body rest directly or indirectly on a common cart with the possibility of rotation relative to it. Moreover, the outer sections of the body have a cantilever part in which at least one discharge hopper is located, and transverse skates are installed between the discharge hoppers.

Further improvement of hopper cars required the development of special designs of transverse skates installed between the unloading hopper located in the inter-body space and the unloading hopper located in the console part of the car. This ridge requires an original reinforced structure, since it should cover a rather large space above the trolley and at the same time not create additional obstacles for loading and unloading cargo, taking into account the need to take into account the specifics of unloading goods with a high degree of caking and have sufficient strength to withstand heavy loads.

Thus, the technical problem that currently exists is the problem of ensuring the strength and reliability of articulated hopper cars with unloading bins in the cantilever parts of the car.

Utility Model Disclosure

The creation of the proposed utility model is aimed at solving the technical problems described above, namely, at creating the design of an articulated hopper car with a discharge hopper in the cantilever part with improved technical characteristics, namely, with increased strength and reliability during operation.

The technical result is to improve the technical characteristics of the hopper car, namely, to increase the strength and reliability of the design of the hopper car and increase the efficiency of unloading of transported goods.

It is proposed to use inclined struts of the transverse skates with the help of struts to connect to the upper shelf of the pivot beam, which will allow transmitting to the pivot beam the force of gravity and the force of longitudinal inertia of the load that arise when the car collides and act on the inclined planes of the transverse skate. It is proposed to connect the joints of the struts with the inclined racks of the transverse skates with horizontal beams, which will allow to transfer part of the longitudinal load from the inclined plane of the transverse ridge from the side of the impact to another, less loaded plane of the transverse ridge. It is proposed that the inclined racks located on the side of the bunker of the inter-body space be interconnected by transverse beams, and the inclined racks placed on the side of the hopper of the cantilever part, also be interconnected by transverse beams.

Thus, according to the utility model, each transverse ridge contains a lattice structure consisting of inclined racks, horizontal longitudinal beams, struts and transverse beams, each pair of inclined racks connected to each other in the upper part and a horizontal longitudinal beam in the middle part, with this, the upper ends of the struts abut against the inclined racks in the places of their connection with the horizontal longitudinal beams, and the lower ends of the struts rest on the top sheet of the pivot beam of the frame, and the inclined racks located on the side of the unloading bunker of the inter-body space are interconnected by transverse beams, and the inclined racks placed on the side of the unloading hopper of the cantilever part are interconnected by transverse beams.

In one embodiment, the junction of the inclined struts with a horizontal longitudinal beam and struts is reinforced with upper overlays.

In one embodiment, the junction of the lower ends of the struts with the upper shelf of the pivot beam is reinforced with lower pads.

In one embodiment, the inclined racks located on the discharge side of the inter-body hopper have a double angle of inclination.

For unloading the transported cargo, each section 3 of the body contains unloading bins 9 located in the inter-body space, and cantilever unloading bins 6 located in the outer cantilever parts of the body. Between the cantilevered unloading bins 6 and adjacent unloading bins 9 installed transverse skates 7.

The transverse skates 7 consist (see Fig. 2-4) of the first and second inclined racks 12 and 17, respectively, the struts 15 and the upper and lower reinforcing plates 14 and 16, respectively, with each pair of inclined racks 12, 17 connected in the upper part of the transverse ridge 7 with each other, and in the middle part - a horizontal longitudinal beam 13, the junction with which and with slopes 15 is reinforced with the help of the upper 14 pads. The struts 15 with their upper ends abut against the inclined racks 12 and 17 at the points of their connection with the horizontal longitudinal beams 13, and their lower ends rest on the top sheet of the pivot beam 5, and the lower ends of the struts 15 are interconnected by the lower plate 16. Thus, the joints of the inclined racks 12, 17 of the transverse skates with struts 15 and with horizontal longitudinal beams 13, as well as the joints of the struts 15 with the upper shelf of the pivot beam 5 are reinforced with upper and lower plates 14, 16 or scarves, since it is in these places that the greatest bending moments that can cause stresses exceeding permissible.

Вторые наклонные стойки 17 также соединены между собой поперечными балками 18, проходящими между смежными стойками 17, с образованием решетчатой конструкции. Первые наклонные стойки 12, размещенные со стороны консольного разгрузочного бункера 6 консольной части вагона, тоже соединены между собой поперечными балками 18 с образованием решетчатой конструкции. Сверху решетчатая конструкция (12, 17, 18) поперечного конька 7 обшита соединенными между собой, предпочтительно посредством сварки, изогнутым стальным листом 19 или набором стальных листов 19.Each of the second inclined racks 17, located on the side of the bunker 9 of the interbody space, has a kink below the junction of the inclined rack 17 with the strut 15, formed by bending the bottom of the inclined rack 17 at an angle

(see Fig. 2) in the direction of the pivot beam, with the formation of a "broken" rack 17 to increase the efficiency of unloading through the unloading bins 9. The second inclined racks 17 are also interconnected by transverse beams 18 passing between adjacent racks 17, with the formation of trellised designs. The first inclined racks 12, located on the side of the cantilever discharge hopper 6 of the cantilever part of the car, are also interconnected by transverse beams 18 with the formation of a lattice structure. On top of the lattice structure (12, 17, 18) of the transverse ridge 7 is sheathed interconnected, preferably by welding, with a curved steel sheet 19 or a set of steel sheets 19.

The first inclined racks 12, horizontal beams 13, the second inclined racks 17, struts 15 and transverse beams 18 are made of a bent “P” shaped profile.

Pads 14 and 16 are made of sheet metal. The struts 15 are based on the top sheet of the pivot beam 5 and are interconnected by lower plates 16.

The first inclined racks 12 in the upper part of the ridge 7 are connected to the second inclined racks 17, which have a double angle of inclination, and in the lower part are based on the transverse beam of the longitudinal 8 ridge of the cantilevered hopper 6.

The transverse ridge 7 from the side of the second inclined racks 17 is connected to the end walls of the discharge hopper 9 and is partially supported by the longitudinal ridge 8 of the discharge hopper 9. The transverse ridge 7 contains 4 pairs of inclined racks 12, 17.

The proposed design of the transverse ridge provides the necessary strength of the transverse ridge when unloading various goods, in particular grain and products of grinding, as well as mineral fertilizers and, accordingly, the operational reliability of the hopper car.

Thus, the proposed hopper car has improved technical characteristics in comparison with the known structures, namely, increased strength and reliability during operation of the car.
