Description

The utility model relates to rail vehicles, in particular, to freight gondola cars with an increased body volume and intended for the transportation of bulk cargo.

There are various technical solutions in this area.

Known RU patent for utility model No. 163324 (IPC B61D3 / 00, B61D17 / 08, publ. 07/10/2016). The gondola car contains a frame mounted on the undercarriage and a body fixed on the frame, consisting of end and side walls with uprights, profiles of the upper trim and sheathing sheets. In the inter-body space of the body, the floor is made lower, and the sheathing sheets and pillars in the lower part of the side walls are made curved with the formation of side walls, the upper part of which is shifted outward of the body relative to its lower part within the size of the rolling stock.

RU patent for invention No. 2539701 is also known (IPC B61D3 / 00, B61D7 / 08, B61D7 / 26, published on January 27, 2015). Gondola for bulk cargo contains running gears and a body mounted on them, consisting of a frame, end and side walls. Unloading hatches are installed along the wagon, fixed by hinges to the lower harness. The end walls are inclined so that their lower parts are located above the pivot beams and connected to them. The floor is formed by inclined surfaces having an inverted V-shape in the cross section of the car, located between the transverse and pivot beams.

So, the RU patent for invention No. 2391239 is known (IPC B61D3 / 00, B61F1 / 00, publ. 06/10/2010), which is adopted as a prototype. A freight wagon with a dead floor contains a frame mounted on two running trolleys, a body mounted on the frame, consisting of side and end walls with uprights, profiles of the upper trim, longitudinal beams and sheathing sheets, couplers and brake equipment. In the inter-body space of the body, a lowering of the floor in the form of a bunker is formed. The inner ends of the supra-body spinal beams of the frame are welded into the transverse beams of the box section, which are connected at the ends to the longitudinal side beams. Between each other, box-shaped cross-beams are connected by longitudinal beams curved along the profile of lowering the floor of the body and welded into the transverse beams curved along the profile of the lower design outline of fitting the body into the dimension and connected to the longitudinal side beams of the frame opposite the middle pillars of the side walls of the body.

Gondola cars with a lower floor level (bunkers) have an increased load capacity, and due to the lack of a roof, they do not have a rigid closed loop consisting of side racks - roof beams - transverse frame beams. Therefore, at the junction of the hopper with the side walls of the car, additional stress arises. To ensure the necessary strength of the entire structure, additional measures are required.

The disadvantage of analogues and prototype is that they do not take into account the additional voltage that occurs at the junction of the hopper with the side walls of the gondola car, and, therefore, the necessary strength and reliability of the entire structure of the gondola car is not provided.

Thus, the technical problem that currently exists is the problems associated with ensuring the high structural strength of gondola cars with increased payload without weighting it. The creation of the proposed technical solution is aimed at solving this technical problem, namely, at creating a body structure with an articulated gondola hopper having improved technical characteristics, namely, increased strength of the hopper in the transition zone to the side walls while optimizing the gondola mass.

The technical result consists in improving the technical characteristics of a body with a hopper of an articulated gondola car, namely, in increasing the strength while optimizing the weight of the gondola car.

The technical result is achieved in that a body with a hopper of an articulated gondola car, including end and side walls with uprights and sheathing sheets, according to a utility model, contains reinforcing elements installed inside the hopper and made of two side sheets located essentially perpendicular to the sheathing sheets and having smoothly curved shape with a decrease in height in the direction of the ends of the reinforcing elements, and the top sheet attached to the upper edges of the side sheets, for example, by welding. One end of each reinforcing element is connected to the floor of the hopper, and the other to the skin of the side wall of the hopper or body. The reinforcing elements are located inside the hopper in the same plane with the beams of the hopper and the racks of the side walls of the body. The reinforcing elements can be made, for example, in the form of a channel.

The essence of the proposed utility model is illustrated by the following graphic materials: figure 1, which shows a General view of the articulated gondola car; figure 2, which shows a section aa; figure 3, which shows a section bB, and figure 4, which presents a perspective view, where:

1 - car body;

2 - a rack of a side wall of a body;

3 - a covering of a side wall of a body;

4 - hopper;

5 - hopper beam;

6 - lining of the side wall of the hopper;

7 - floor of the hopper;

8 - side sheet of the reinforcing element of the hopper;

9 - top sheet of the reinforcing element of the hopper.

The body 1 with the articulated gondola hopper includes end and side walls with uprights 2 and casing sheets 3, and a bunker 4 containing end walls and side walls with beams 5 and casing sheets 6, floor 7 with unloading hatches. Reinforcing elements are installed on the side walls of the hopper 4 inside the body 1.

Each of the reinforcing elements is made of two side sheets 8, located essentially perpendicular to the sheathing sheets, and an upper sheet 9 welded to the upper edges of the side sheets 8, with the formation of a channel cross section. The lateral sheets 8 of the reinforcing element are located in the middle part on the inclined side wall of the hopper 4, while one end of each reinforcing element is connected to the floor 7 of the hopper 4 (Fig. 3), and the other end with the skin 6 of the side wall of the hopper 4 or with the skin 3 of the side body walls 1. The side sheets 8 from the upper edges are made with decreasing height in the direction of their ends so that in the middle part the height is greatest, and at the ends it is zero. The top sheet 9 is made curved to mate with the upper edges of the side sheets 8.

The reinforcing elements of the hopper are located in the same plane with the beams 5 of the hopper 4 and the racks 2 of the side walls of the body 1, which ensures the transfer of load between the hopper 4 and the body 1 of the car.

The advantages of the proposed technical solution over the known analogues:

1. Due to the curvature of the reinforcing elements, which gives additional rigidity to the structure, a smooth transition of the top sheet 9 of the reinforcing element to the floor 7 of the hopper 4 and to the skin of the hopper 4 or body 1 is ensured, which eliminates the stress concentration in these places.

2. Internal reinforcement of the hopper in the form of reinforcing elements allows to provide the necessary structural strength without increasing the dimensions of the profiles of the body racks, which allows the maximum use of the gondola car dimension. Local reinforcing elements in the form of channels of variable cross-section allow introducing reinforcement in the local zone, which minimizes the gondola body weight (similar structures are, on average, 100 kg heavier per body).

Thus, the proposed body with a silo of an articulated gondola car has improved technical characteristics compared to known structures.
