Description

The invention relates to the field of railway transport, in particular to the structures of roofs, end and side walls of covered wagon bodies.

A covered freight railway car is known, in which a body mounted on biaxial bogies, in the upper part of which a roof is installed, is made in the form of a metal frame formed by a set of arcs and sheathed outside with corrugated sheets (patent RU No. 141366, dated 08/22/2013, "Covered freight railway car ", B61D 17/12, B61D 3/00).

The disadvantages of the design are the presence of a break in the functional connection between the platforms on the roof of the car, a large range of corrugated profiles used, requiring the installation of plugs on the corrugations when assembling the car body.

Also known and accepted as a prototype is the roof of a freight hopper car made of at least one composite material as a self-supporting shell. The shell is made in the form of an upwardly convex chute with end walls (patent RU No. 149133, dated November 06, 2013, "Hopper car roof", B61D 17/12, B61D 3/00).

The disadvantages of the prototype design are the irrational arrangement of the platforms on the roof of the car for servicing loading hatches, the presence of low-height fences on the platforms from the outside, the inconvenience of servicing the loading hatches due to the direction set across the car for opening the hatch covers, the absence of a ladder on the opposite end wall of the car and maintainability due to the combined use of metal and composite materials.

The technical result to which the invention is directed is the creation of a covered carriage for the carriage of goods requiring protection from atmospheric precipitation with improved maintainability and ease of maintenance, expanded functionality, accelerated loading process, safer and more convenient movement of service personnel along the stairs and the roof of the car.

The specified technical result is achieved due to the fact that a frame with an anti-slip flooring, an automatic brake, a parking brake, an automatic coupler, a body with sliding doors and a mechanism for their movement are installed in a covered car on the chassis. The roof is made in the form of a frame sheathed from the outside with sheet metal, formed by a set of arcs and is fixedly connected to the upper straps of the end and side walls. Ventilation devices are provided at the ends of the roof. The side walls, end and sloped parts of the roof are sheathed on the outside with smooth sheet metal, the sheathing of the middle part of the roof consists of a combination of smooth sheet metal and at least five rectangular inserts of rolled steel with a corrugated surface, four of which surround the opening of each hatch, and the fifth, located on the transverse the axis of the car is a functional connection between the platforms. The end walls are equipped with ladders located diagonally relative to the longitudinal axis of the car and handrails for lifting to the roof of the car. In the middle section of the roof, at least four technological loading hatches are installed, and on the extreme sections of the roof, in the area of each pair of hatches, there is at least one platform made of sheet metal with a corrugated surface, which has vertical folds along the car on each side and holes in the horizontal section for runoff of atmospheric precipitation.

The invention is illustrated by drawings, which do not cover and even less limit the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of implementation:

in fig. 1 - covered carriage;

in fig. 2 - covered carriage, type A;

in fig. 3 - covered carriage, type B.

The inventive covered carriage, containing a frame 2 (Fig. 1, Fig. 3) mounted on the undercarriage 1 (Fig. 1, Fig. 3) with an anti-slip flooring 3 (Fig. 2), a body 4 (Fig. 1) with sliding doors 5 (Fig. 1, Fig. 3) and their movement mechanism 6 (Fig. 1), roof 7 (Fig. 1, Fig. 3) with ventilation devices 8 (Fig. 1, Fig. 2, Fig. 3) at its ends, made in the form of a frame 9 sheathed on the outside with sheet metal (Fig. 2, Fig. 3), formed by a set of arcs 10 (Fig. 2), fixedly connected to the upper end straps 11 (Fig. 1, Fig. 2, Fig. 3) and side walls 12 (Fig. 1), automatic brake 13 (Fig. 1, Fig. 3), parking brake 14 (Fig. 1, Fig. 3) and automatic coupler 15 (Fig. 1, Fig. 2, Fig. . 3). Side walls 12 (Fig. 1), end walls 16 (Fig. 3) and inclined 17 (Fig. 1, Fig. 2, Fig. 3) parts of the roof are sheathed from the outside with smooth sheet metal, sheathing of the middle part 18 (Fig. 2) of the roof consists of a combination of smooth sheet metal and at least five rectangular inserts made of rolled products with a corrugated surface, four of which encircle the opening of each hatch 19 (Fig. 2, Fig. 3), and the fifth, located on the transverse axis of the car, is a functional connection between the platforms 20 (fig. 2, fig. 3). The end walls 11 (Fig. 1, Fig. 2, Fig. 3) are equipped with ladders 21 (Fig. 3) and handrails 22 (Fig. 3) for lifting to the car roof, located diagonally relative to the longitudinal axis of the car, in the middle roof section 18 (Fig. 2) installed at least four technological loading hatches of a round shape 19 (Fig. 2, Fig. 3), and on the extreme sections of the roof 17 (Fig. 1, Fig. 2, Fig. 3) in the region of each pair of hatches at least one platform 20 (Fig. 2, Fig. 3), made of sheet metal with a corrugated surface, having vertical folds along the carriage on each side and holes in the horizontal section for atmospheric precipitation drainage.

The combination of essential features of the invention allows to speed up the loading process due to the presence of covered technological hatches on the roof of the car. Due to the use of the well-established technology of the car assembly and the identity of materials, the serviceability and maintainability of the car are increased. The location of the stairs, handrails and platforms facilitates easy access to the car roof and free access to loading hatches from either side of the car. The platforms and the functional transition between them ensure the safe movement of service personnel on the roof of the car.
