Description

The utility model relates to railway transport and relates to the construction of hopper cars designed for the transportation of bulk cargo.

Analogs of hopper cars are hopper cars described in the book “Design and Calculation of Cars”, authors Lyukin VV, Shadur LA, Koturanov VK, Khokhlov AA, Anisimov PS, Moscow 2000, recommended as a textbook for university students of railway transport. Typical technical solutions for hopper cars are shown in Fig. 9.17, p. 498; 10.9 p. 577; 11.18 p. 653; 11.24 p. 659 and others. All of them include a power frame of the body, equipped with a spinal beam and two pivot beams, through which the car body rests on the undercarriage.

The disadvantages of analogues include the fact that their spinal beams are made of two welded I-beams, which have a large mass and reduce the useful volume of hopper cars.

As a prototype of a utility model, you can take the hopper hopper car, protected by a utility model certificate No. RU 44091 U1, B61D 7/02 according to the application No. 2004126360/22 of 09/07/2004, "Hopper car." This hopper car contains two pivot beams and a spinal beam, which is made of the T-type on the section between the pivot beams, the horizontal shelf of which closes with the inclined sheets of the bunkers, and the vertical rack of the brand together with the inclined sheets of the bunkers forms a bulk cargo breaker.

The dimensions of the shelves of the T-beam are determined by the angle of inclination of the longitudinal walls of the bunkers, which depends on the properties of the transported cargo - the angle of repose. Considering that the range of rolled steel products is limited in size, it is necessary to produce such a beam from parts by welding a horizontal shelf with a vertical one, and there are technological difficulties in eliminating welding deformations that lead to the bending of the beam in both transverse and longitudinal planes, which is a technical problem, because increases the complexity of their installation in the frame of the car.

The technical result of the claimed utility model is to reduce the complexity of manufacturing a hopper car.

The technical result is achieved by the fact that the central beams of the cantilever frames are interconnected by a spinal beam, consisting of separate parts of different lengths and different cross sections, interconnected along the inclination planes of the walls of the discharge bins. A part of the spinal beam located along the longitudinal walls of adjacent bunkers is made by connecting a horizontal plate to the longitudinal walls of adjacent bunkers in their upper part, forming a triangular cross section. A part of the spinal beam located between the end walls of adjacent bunkers is made of box-shaped quadrangular section of two parts, the vertical walls of the lower of which are slanted upward at an angle equal to the slope of the end walls of adjacent bunkers, and the upper part is made curved congruently to the vertical walls of the lower part. Parts of the spine beam located along the longitudinal walls of adjacent bunkers are connected to parts of the spine beam located between the end walls of adjacent bunkers, in the plane of inclination of the end walls of adjacent bunkers, the plate of the part of the spine beam located along the longitudinal walls of adjacent bunkers is connected to a part of the spine beam, located between the end walls of adjacent bins, in the plane of its lower horizontal surface. The central beams of the cantilever frames are connected to a part of the spinal beam located along the longitudinal walls of adjacent bunkers through overlays installed between them on the end walls of adjacent bunkers.

The essence of the claimed utility model is illustrated by drawings, where:

in FIG. 1 shows a hopper car,

general form; in FIG. 2 is a view A in FIG. one;

in FIG. 3 is a section along the line BB in FIG. 2;

in FIG. 4 is a section along line BB in FIG. 2;

in FIG. 5 is a section along the line G-G in FIG. four.

The hopper car (Fig. 1) includes a body 1 comprising side 2 and end 3 walls connected between itself and the frame 4. Frame 4 (Fig. 2) includes a spinal beam 5, transverse beams 6, longitudinal beams 7, discharge bunkers 8 located between the above beams, cantilever frames 9 containing frontal beams 10, pivot beams 11, side beams 12 and central beams 13. The central beams 13 of the cantilever frames 9 are interconnected by a spinal beam 5, which consists of separate parts 14 and 15 connected among themselves: part 14 is located along the longitudinal x walls 16 of adjacent bins, part 15 is located between the end walls 17 of adjacent bins. Part of the spinal beam 14 (Fig. 3), located along the longitudinal walls 16 of adjacent bins, is made by connecting a horizontal plate 18 of the longitudinal walls 16 of adjacent bunkers 8 in their upper part, forming a triangular section. A part of the spinal beam 15 (Fig. 4, Fig. 5) located between the end walls 17 of the adjacent bunkers 8 is made of a box-shaped quadrangular section of two parts, the vertical walls of the lower 19 of which are slanted upward at an angle equal to the inclination of the end walls 17 of the adjacent hoppers 8 (surface D), and the upper part 20 is made curved congruently to the vertical walls of the lower part 19. A part of the spine beam 14 located along the longitudinal walls 16 of adjacent bunkers is connected to a part of the spine beam 15 located between end walls 17 of adjacent bins 8, in the plane of its lower horizontal surface W (Fig. 4).

The use of the design of the inventive hopper car of a spinal beam of various lengths and different cross sections, interconnected along the plane of inclination of the walls of the discharge hoppers, simplifies the design of the hopper car and reduces the complexity.
