Abstract

FIELD: railway transport.

SUBSTANCE: invention relates to design of combination hopper car for transportation of alumina and products of its processing. Proposed combination hopper car 1 has running gear, hopper compartment 5 and carried material chamber adjoining hopper compartment at ends and provided with door apertures 8 for motor cars, rigidly connected with frame equipped with bolsters. Hopper car has four turnable struts 9. Upper end of each strut thrusts against place of connection of separating wall between hopper compartment and carried material chamber and upper binding of car side wall, and lower end rests on bolster, thus forming truss shape unit with load-bearing hopper and frame. Turnable struts are hinge connected to hopper compartment at corners. Seats for turnable struts are made on bolsters to mount turnable extensible rods.

EFFECT: reduced weight of car at preservation of its load-carrying capacity.

Description

The invention relates to railway transport, and in particular to the body structure of a combined hopper car designed for transportation of alumina and objects of its processing.

Known for the body of a bunker car containing side and end walls, a perforated bottom, a frame made of spinal and side beams interconnected by end, pivot and intermediate beams. The spinal beam of the frame is made in a U-shape, on the upper horizontal shelf of which an I-beam is installed. On the last one another I-beam is installed, with which a perforated underbody is connected (a.c.SSSR N634986, M class B 61 D 7/00, 1977).

Known for the body of a bunker car, consisting of side and end walls, a frame made of spinal and side beams interconnected by end, pivot and intermediate beams. The spinal beam is box-shaped from two Z-shaped profiles. In this design of the body of the bunker car, the issue of improving the shattering of cargo has been resolved. For this, the box-shaped frame element is equipped with a gable ridge, overlapping its upper horizontal surface and inclined flaps, overlapping the vertical walls and lower shelves of the box-shaped section of Z-shaped profiles. In this case, the inclined guards, on the one hand, are rigidly connected to the gable skate, and on the other, to the internal inclined walls of the bunkers (see, book by I.F. Pastukhov, V.V. Lukin, N.I. Zhukov. "Wagons", Publishing house "Transport", M., 1988, p.165, Fig. 8, 17).

The disadvantages of analogues include the fact that the wagons have a large dead weight, and only bulk materials are transported.

The prototype of the invention is the body of the hopper car, protected by patent for invention No. 2181089 of the Russian Federation of 04/10/2002.

The prototype body is three-section with storage chambers adjacent to the ends of the hermetic bunker compartment for storage of the transported material. Vertical power end walls closing the bunker compartment of the car body onto the car carts are placed at a predetermined distance from the body supports, above which chambers for storing the transported material are symmetrically placed. The cameras are equipped with double-sided doorways for driving cars.

The weakening of the doorways for the entrance of the car side walls of the car is compensated by the installation of springs and their uprights.

The disadvantage of the prototype is that the car has a large dead weight.

The aim of the invention is to reduce the weight of the combined hopper car while maintaining its carrying capacity by strengthening the power circuit of the body in such a way as to preserve through doorways in the storage chambers of the transported material, without blocking them with stationary support struts that impede the entry of vehicles during loading and unloading operations.

The essence of the invention is to create a combined hopper car containing a chassis, a hopper compartment and adjoining at the ends of the storage chambers of the transported material with doorways for the entry of autocar, rigidly connected to the frame of the car, equipped with beams, equipped with four rotary struts, the upper end of each of which abuts against the junction of the demarcation wall between the hopper compartment and the storage chamber of the transported material and the upper strapping of the side wall of the car, and the lower mounted on a pivot beam, forming a truss type assembly with a power hopper and a frame: swivel struts at the corners of the hopper compartment are pivotally connected to it, and on the pivot beams there are seats for pivoting trays in which pivoting movable pins are installed; swivel is made in the form of a ball joint.

The invention is illustrated by drawings, where

figure 1 shows a General view of a combined hopper car with braces installed in the working position;

figure 2 - General view of the strut in the working position;

figure 3 is a General view of the strut in a rotated position to ensure loading (unloading) operations;

figure 4 shows the lower support, strut in the working position.

The combined hopper car 1 (Fig. 1) is equipped with rolling trolleys 2, mates with the combined body 3 through thrust bearings 4, mating with pivots and supports of the rolling trolleys 2. The body 3 is three-section, it contains a sealed compartment of hopper type 5 for transporting alumina loaded through hatches 6 and discharged into the rail space through hatches 7 placed on the bunkers. To the compartment 5 at the ends are adjacent chambers for storing materials from aluminum alloys, equipped with doorways 8, the dimensions of which provide the entrance and cameras of cars during loading (unloading) operations through cargo platforms. The cameras are equipped with trays 9, floorings 10, immovable power frames 11 and clamping devices 12. The doorways are closed by doors 13. The body 3 is equipped with lower brackets 14 and a spinal beam 15, on which the power walls 16 that separate the compartment 5 and the storage chamber 17 of the transported materials.

Braces 9 (figure 2) consist of an upper adjustable support 18, brace 19, handle 20, pin 21 and stopper 22 (figure 4).

To ensure access to the camera 17 storage of the transported material during loading (unloading) operations, the rotation of the strut 9 (Fig.1, 2) to the inoperative position (Fig.3) is as follows.

Using the handle 20 (FIGS. 2, 3, 4), the pin 21 is rotated (FIGS. 2, 3, 4), while due to the stopper 22 (FIG. 4) and the screw groove on the pin 21, it simultaneously rises by an amount screw groove step. After turning 90 ° in the upper support, the strut occupies a position perpendicular to the doorway of the car body (Fig. 3), i.e. frees access to the camera 17 storage of the transported material. The installation of the strut 9 in the working position is carried out after loading (unloading) work in the reverse order.

The use of rotary struts allows you to redistribute the forces acting on the power elements of the body of the combined hopper car, i.e. significantly reduce efforts in the spinal beam, is to reduce the mass (weight) of the combined hopper car itself while maintaining its load capacity.
