Abstract

FIELD: car-building.

SUBSTANCE: invention relates to railway equipment, particularly, to dump wagon, and can be used in transportation and unloading of loose cargo. Dump car comprises dump cylinders, lower and upper frames, longitudinal board (1) with inner sheet (3), protective shield (4) of load spill. Longitudinal edge of protective shield (4) is attached to lower edge of inner sheet of side along entire length of sheet. Side parts of shield (4) envelope loop sides and are fixed on them. On longitudinal beam of upper frame along its entire length is fixed an additional sheet to form a volume of closed side position between upper part of surface of protective shield and an additional sheet.

EFFECT: higher efficiency of protection of load of fine fraction from spillage during car motion.

Description

The invention relates to car building, in particular to a dump truck of the dumpcar type, and may find application in the transportation and unloading of bulk cargo, such as sand, rock masses from quarries, as well as mineral fertilizers.

A big drawback of existing models of dump cars is the spilling of cargo from the body while moving through the gap between the side and the visor of the upper frame. During the movement of the dumpcars from the place of loading to the place of unloading at a distance of 30-50 km, the railway track becomes clogged with waking up cargo and its direct losses.

A self-unloading car of the dumpkar type is known (RU 2521074, IPC B61D 9/10, B62D 33/03, publ. 06/27/2014), including a body, a mechanism for opening and closing the side, located on the end wall of the car, the upper frame, along the longitudinal beam which has a visor of radius R attached to protect it from spilling cargo. The inner side of the bead in the train position is located above the visor, and when the side is opened, the bead sheet rotates along the visor around the bead axis, fixed in the loop of the upper frame.

The disadvantages of the described dump car can be attributed to the ineffectiveness of protection against cargo spillage during the movement of the train, since there is a vertical gap between the inside sheet of the side and the visor, which is reduced by compensating slats in the manufacture of the dump car, bringing it to 5-10 mm. But even with this gap, the load is spilled during the movement of the train, especially when the cargo is transported in very small fractions. In addition, during the operation of a dump car, an increase in clearance occurs over time due to deformation of the side.

The invention solves the problem of improving the efficiency of protecting the cargo of small fractions from spillage during the movement of the car due to structural changes in the node connecting the side with the upper frame.

To achieve the technical result in a car of the dumpcar type, including unloading cylinders, lower and upper frames, a longitudinal side with a fixed inner sheet, a protective visor from spilling cargo, it is proposed to attach the longitudinal edge of the protective visor to the lower edge of the inner side sheet along the entire length of the sheet, and the side parts of the visor bend around the hinges of the side and are fixed on them. It is proposed to fix an additional sheet on the longitudinal beam of the upper frame along its entire length with the formation of a volume in the closed position of the bead between the upper part of the surface of the protective visor and the additional sheet.

The accompanying description of the drawings shows:

FIG. 1 - the longitudinal side of the body with a loop;

FIG. 2 - a longitudinal beam of the upper frame with a loop;

FIG. 3 - the longitudinal side of the body and the longitudinal beam of the upper frame assembly, the board in the closed position;

FIG. 4 - the same, the board in the open position.

In the drawings, the following notation:

1 - longitudinal board;

2 - a loop of a longitudinal board;

3 - inner side sheet;

4 - a protective peak;

5 - a longitudinal beam of the upper frame;

6 - loop of the longitudinal beam of the upper frame;

7 - an additional sheet mounted on a longitudinal beam;

8 - volume for the accumulation of spilled cargo.

The longitudinal side 1 includes an inner sheet 3, to which a visor 4 is welded along the entire length, the lateral parts of which surround the loops 2 of the longitudinal side 1 and are welded to them. The upper frame includes a longitudinal beam 5 with a loop 6. In the longitudinal beam 5, an additional sheet 7 is welded along the entire length.

When the dump car is moving, the cargo of a small fraction through a gap of about 3-5 mm falls into the volume 8 formed between the additional sheet 7 of the longitudinal beam 5 of the upper frame and the upper part of the surface of the protective visor 4. In the formed volume 8, the cargo accumulates, which gradually fills this volume 8, and the spilling of cargo onto the rails during movement stops. Waking up very little is possible in the initial period of movement for a short time, until volume 8 is filled.

Thus, thanks to the proposed constructive change in the assembly of the connection between the side and the upper frame, the efficiency of protecting the small fraction cargo from spillage during the movement of the car increases compared to the technical solution described in the closest analogue.
