Description

 The invention relates to railway transport, and in particular to the design of bunker cars for transportation of alumina.

 A hopper car is known, protected by a certificate for a utility model of the Russian Federation 17497, in which at the level of the spinal beam with support on it and the sidewalls of the body against each vertical strut, power beams are rigidly fixed on which mesh-type power flooring blocks are fixed, on which solid loads are mounted.

 The disadvantages of the analogue include the fact that for loading solid loads (rolled metal) into the car, tight side doors are required, which are time-consuming to seal.

 The prototype of the invention is a hopper car according to the patent of the Russian Federation 2161103, IPC 7 В 61 D 7/00, published on 12/27/2000, of the bunker type for transporting alumina in a sealed bunker compartment of a body made in three sections, in which a bunker sealed compartment of a body is made with vertical end face walls adjacent to chambers equipped with leaky doorways for the entry of forklifts.

 The disadvantages of the prototype should include the fact that the camera is leaky type are loaded unevenly, which leads to the overload of the car in one direction. In addition, the disadvantages of the prototype include the fact that the car is equipped with four doorways that weaken its end parts. In addition, to secure a solid cargo-rental requires the presence of a doubled number of clamping mechanisms.

 The aim of the invention is to increase reliability by ensuring uniform loading of the car, simplifying its design by reducing the number of through doorways and increasing the volume of chambers for transporting alumina.

 This goal is achieved due to the fact that in a hopper-hopper car containing a body made of three compartments, rigidly fixed to the power frame, the cargo compartment of which is equipped with a doorway with leaky doors, a floor for the passage of the forklift and a clamping mechanism, loading and unloading hatches for alumina, the middle cargo compartment is closed on each side by vertical force walls of the extreme airtight compartments for alumina equipped with loading and unloading hatches, and to one of the vertical ovyh walls sealingly fixed type cover biasing mechanism, wherein the sealed type extreme compartments connected pipes.

 The technical result achieved by the invention is to simplify the design and increase reliability due to the fact that when loading a car with rolled metal and scrap for metallurgical plants, the weight of the car is not disturbed, the volumes for placing alumina are increased due to the hinged parts of the ends of the car.

 The number of doorways is halved, the number of loading hatches and discharge bins is also reduced. Alumina loading is carried out uniformly due to the bottom drainage system, creating two airtight compartments.

The invention is illustrated by drawings, where:
figure 1 shows a side projection of a hopper car;
figure 2 is an end view of a hopper car;
figure 3 is an isometry of the reinforcement of the end wall of the hopper car;
in FIG. 4 is a longitudinal section of a hopper car loaded with alumina and rolled metal.

 The hopper wagon 1 (Fig. 1) contains a body supported by a spinal beam 3, a pivot beam equipped with thrust bearings 4, supported by biaxial bogies 5. The body 2 is divided into three compartments: the middle compartment 6 is designed for transportation of rolled metal and scrap, and two extreme compartment 7 are designed to transport alumina. The middle compartment 6 is equipped with two non-tight doors 8, covering the cargo compartment 6. The extreme compartments 7 for alumina are equipped with loading hatches 9 on the roof of the body 2 and unloading hatches 10 located in the bottom of the bunkers of the extreme compartments 7. The outer compartments 7 are connected by pipes 11, forming a siphon system for filling compartments 7 with alumina, the fluidity of which is higher than the fluidity of a liquid such as kerosene.

 The end inclined walls 12 (FIG. 2) of the body 2 are supported by a transverse beam 13 located in the plane of the pivot beam 14. Between themselves, the transverse beam 13 and the pivot beam 14 are connected by inclined beams 15 converging at the location of the thrust bearing 4. The inclined plane 12 is supported by P- shaped beams 16 and 17 (Figure 3).

 To secure the rental 18 (Figure 4) use the clamping mechanism 19 and the rack 20.

 The operation of the hopper car 1 is as follows. Alumina is poured into the extreme compartments 7 through loading hatches 9. The connection in the bottom of the hoppers with pipes 11, forming a siphon system, allows you to evenly load alumina into compartments 7. To load compartment 6 with rolled metal and scrap metal from the loading platform, the doorway is opened by releasing the door 8 from the locks-fasteners, the posts 20 are removed from the loading side, the pinch mechanism 19 is compressed to the stop. Then vehicles are delivered to the compartment 6 rolled metal and scrap, packaged or stacked in boxes. Material loading in the form of ingots and plates by the forklift is carried out in such a way that there is a gap between them to ensure the operation of the forklift. Clearances are provided by installing gaskets made of wood or other materials.

 The invention provides for the transportation of alumina and rolled carriages of a simplified design, which ensures a reduction in the metal consumption, labor intensity and nomenclature of the used components and parts.
