Description

The utility model relates to the field of transport and, more specifically, to railway freight cars.

A patent for a utility model of the Russian Federation No. 63305 is known (priority date: 01/22/2007, publication date: 05/27/2007) "Cargo car body", which contains a frame on which side and end walls are mounted, while the end wall is made of top trim, horizontal belts, two side racks, reinforcing racks, lower trim, sheathing sheets. Horizontal belts are parallel to the upper and lower harnesses across the entire width of the end wall. One of the reinforcing posts is installed between the lower and middle horizontal belts. Two other racks are installed under the lower belt.

The disadvantage of the end walls of this body of a freight car is the insufficient strength of the end walls due to the fact that the horizontal belts do not contain additional reinforcing elements.

A patent for utility model No. 170074 is known (priority date: 08/08/2016, publication date: 04/13/2017) "Gondola", which includes a body in which each end wall consists of a lining and a frame in the form of reinforcing elements. It has two reinforcing racks for connecting the end wall to the base, while the reinforcing racks have three walls, two of which, the side, are made in the form of flat plates arranged vertically, and one, the front, combines the side. Moreover, each side wall has a bend in the corresponding vertical plane in which it is located, directed outward of the body.

The known end wall includes horizontal reinforcing elements that do not contain additional stiffening elements, which can lead to insufficient stability of the horizontal elements and the end wall to bending moments arising from the pressure carried in the cargo body, which is a disadvantage of the known open wagon.

The closest technical solution to the proposed utility model is the end wall of the open wagon, known from the patent for utility model of the Russian Federation No. 108013 (priority date: 01/13/2011, publication date: 09/10/2011), including the upper strapping rigidly connected to the sheet skin, which is reinforced upper, lower, middle horizontal belts and vertical reinforcing elements symmetrically located relative to the axis of the end wall. At the same time, reinforcing pads located in the center of these beams and symmetrically with respect to the axis of the end wall are installed on the upper harness and the upper horizontal belt; reinforcing pads are mounted on two extreme vertical reinforcing elements above and below the lower horizontal belt.

Reinforcing pads located on horizontal belts and vertical belts do not provide an increase in strength along the vertical reinforcing elements, and reinforcing pads installed on vertical reinforcing elements do not prevent stresses along the horizontal belts. Another disadvantage of the prototype is an increase in the thickness of horizontal belts due to the presence of reinforcing pads on them.

The technical result of the claimed utility model is to increase operational reliability by increasing the strength of the end walls while increasing the strength characteristics of the horizontal beams of the end walls.

In this case, the profile of the end wall does not increase in terms of increasing the thickness of horizontal beams.

In addition, the carrying capacity of cars with installed declared end walls is further increased.

 In addition, due to the presence of ribs at the intersection of horizontal and vertical beams, the rigidity of the carcass increases, which also affects the increase in the strength of the end wall of the car.

The technical result is achieved due to the fact that the end wall of a freight car contains a frame made of horizontal and vertical beams and a casing installed on the frame, while reinforcing ribs are installed at the junction of horizontal and vertical beams inside horizontal beams. In this case, the ribs can be located symmetrically with respect to the corresponding walls of the vertical beams.

The end wall of a freight car at the intersection of horizontal beams with vertical beams may contain two ribs installed with an offset relative to the walls of the vertical beams.

The end wall of a freight car may contain ribs installed with an offset relative to the walls of the vertical beams, in which the outer surface of the walls of the vertical beams and the inner surface of the pair of ribs are in the same plane.

The end wall of a freight car may contain ribs installed with an offset relative to the walls of the vertical beams, in which the inner surface of the walls of the vertical beams and the outer surface of the pair of ribs are in the same plane.

The proposed technical solution is illustrated by drawings, where the figures shown:

FIG. 1 - end wall of the car,

FIG. 2 - section aa horizontal beam,

FIG. 3 - frame end wall,

in which

1 - horizontal beams;

2 - vertical beams;

3 - casing;

4 - ribs;

5 - upper harness.

The end wall (Fig. 1) of a freight car contains a frame made of horizontal beams 1 and vertical beams 2, and a sheath 3 installed on the frame. At the same time, two ribs 4 are installed inside the horizontal beams 1, at the points of intersection with the vertical beams 2 .

The end wall of a freight car at the intersection of horizontal beams 1 with vertical beams 2 may contain two ribs 4 installed with an offset relative to the walls of vertical beams 2.

The end wall of a freight car may contain ribs 4 mounted with an offset relative to the walls of the vertical beams 2, in which the outer surface of the walls of the vertical beams 2 and the inner surface of the pair of ribs 4 are in the same plane. This installation of the ribs 4, with an offset relative to the walls of the vertical beams 2, also allows you to increase the stability of the horizontal beams 1 to the loads.

The end wall of a freight car may contain ribs 4 mounted offset from the walls of the vertical beams 2, in which the inner surface of the walls of the vertical beams and the outer surface of the pair of ribs 4 are in the same plane. This arrangement of the ribs 4 also increases the strength of the end wall along the vertical beams 2.

The end wall of a freight car may contain ribs 4 installed with an offset relative to the walls of the vertical beams 2, in which the inner surface of the wall of the vertical beam and the outer surface of the ribs are in parallel planes at a distance of not less than 1 mm.

Each rib 4 can be installed so that it is a continuation of the walls of the vertical beams 2 in the inner cavity of the horizontal beams 1. As a result, the walls of the vertical beams 2 are connected at the points of their intersection with the horizontal beams 1 using ribs 4. That is, the walls of the vertical beams 2 can be connected from the lower trim (not shown in the figures) of the end wall through the walls of the horizontal beams 1 to the upper trim 5.

Inside the beams of the upper strapping 5 can be installed ribs 4 in the same way as is done inside the horizontal beams 1.

In section AA, depicted in FIG. 2, horizontal beams 1 contain three equally spaced pairs of ribs 4.

In FIG. 3 shows a frame of the end wall of a freight car. In FIG. 3 it is seen that due to the presence of several pairs of ribs 4 installed inside the horizontal beams 1, an increase in the strength of the frame and the operational reliability of the end wall is provided.

The ribs 4 can be made of steel sheets.

Under extreme operating loads (collision of cars, emergency braking, sudden pulling away, etc.), longitudinal forces from automatic couplers (not shown in the figures), through a rigid power frame formed by vertical beams 2 and horizontal beams 1, inside of which in places of their intersection with vertical beams 2, there are two ribs 4, the loads are distributed evenly over the entire surface of the end wall. Due to the extensive (uniform) distribution of the power flow, the power elements (ribs 4) of the end wall are involved, while the horizontal beams 1 and vertical beams 2 are not overloaded by the stress state. In addition, even after the termination of the extreme loads, the beams 1 and 2 do not receive permanent deformations . Strength is also provided under extreme impact on the end wall, followed by subsequent inertial effects of bulk cargo. In this case, a further reaction from the inertial impact on the end wall is perceived along the horizontal beams 1 in the horizontal section and along the vertical beams 2 and ribs 4 in the vertical section.

Under the conditions of operation of freight cars with end walls of the claimed design, during accelerations and braking, a significant bulk of bulk cargo acts, while minimizing the effect of residual deformations in the frame profile.

The claimed utility model can be used in the construction of the end walls of gondola cars.
