RU179444U1 - HOPPER WAGON FOR THE CARRIAGE OF HOT PELLETS AND AGLOMERATE - Google Patents

Abstract

A hopper car for the transport of hot pellets and sinter, containing a body, which is a frame with a frame mounted on it, consisting of side and end walls, two discharge bins with covers, an unloading mechanism, a chassis, side walls of the frame consist of racks, lining, the upper and lower harnesses, the end walls of the frame consist of the upper harness, upper, middle and lower transverse beams, longitudinal beams, sheathing. The technical result is to increase the strength of the end wall of the body of the hopper car due to it is connected by an additional pair of braces installed at an angle relative to each other, the upper transverse beams of the end wall and the frame of the spinal beam, as well as by welding reinforcing ribs at the junctions of the longitudinal and transverse beams. Additional braces are located relative to each other at an angle enclosed in a range from 20 degrees to 45 degrees. When the angle is greater than 45 degrees, it is impossible to sufficiently reinforce the end wall beam, if the angle between the additional braces is less than 20 degrees, then the braces will poorly absorb the loads from the periphery of the end wall. The joints of the longitudinal and transverse beams are reinforced with ribs.

Description

The utility model relates to railway transport, in particular to hopper cars designed for the transportation of pellets and sinter and their mechanized unloading.

A well-known hopper car for transporting hot pellets (utility model of the Russian Federation No. 67942 dated 10.11.2007), comprising a body, which is a frame with a frame mounted on it, consisting of side and end walls, two discharge hoppers with covers, a longitudinal ridge, an unloading mechanism and running gear. Side walls of the frame consist of uprights, upper and lower strapping, braces and sheathing, end walls of the frame consist of upper strapping, transverse, longitudinal beams, sheathing.

The prototype of the proposed utility model is a hopper car model 20-4015, which consists of a body, unloading mechanism, running gears, auto-brake, parking brake, shock-pull device (Reference album. Freight cars of 1520 mm gauge railways. 002I-2010 PKB CV, p. 250).

Modern car building is aimed at improving the technical and economic indicators of hopper cars in connection with an increase in the axial load and the volume of cargo carried, a structural drawback of the known designs of hopper cars for transporting pellets and sinter is the insufficient strength of the end walls due to the fact that the braces connect only the lower and the middle transverse beams, and the design does not provide stiffeners at the junction of the longitudinal and transverse beams.

The technical problem to be solved is the insufficient strength of the end wall of the hopper car body.

The technical result of the claimed utility model is to increase the strength of the end wall of the body of the hopper car by connecting a pair of braces installed at an angle relative to each other, the upper transverse beams of the end wall and the frame of the spinal beam, as well as by welding reinforcing ribs at the junction of longitudinal and cross beams.

To achieve the specified technical result in a hopper car containing a body, which is a frame with a frame installed on it, consisting of side and end walls, two unloading bins with covers, unloading mechanism, chassis, side walls of the frame consist of racks, lining, the upper and lower harnesses, the end walls of the frame consist of the upper harness, upper, middle and lower transverse beams, longitudinal beams, sheathing, while the upper transverse beams of the end wall are connected to the spinal beam of the frame by a pair braces, which are located relative to each other at an angle enclosed in a range from 20 degrees to 45 degrees. When the angle is greater than 45 degrees, it is impossible to sufficiently reinforce the end wall beam, if the angle between the braces is less than 20 degrees, then the braces will poorly absorb the loads from the periphery of the end wall. The joints of the longitudinal and transverse beams are reinforced with ribs.

The proposed utility model is illustrated by graphic material:

FIG. 1 is a side view of a hopper car;

FIG. 2 - end view of a hopper car;

FIG. 3- view of the end wall with reinforcing ribs.

The hopper car for the transportation of pellets and sinter (Fig. 1) contains a body 1, which is a frame 2 with a frame mounted on it, consisting of side 3 and end 4 walls (Fig. 2), two discharge bins 5; chassis 6. End walls 4 consist of an upper strapping 7, transverse 8, longitudinal 9 beams.

The lower and middle transverse beams 8a of the end wall 4 (Fig. 2) are connected to the spinal beam of the frame 2 by braces 10 (Fig. 3).

In order to increase the structural strength of the end wall 4, the upper transverse beams of the end wall 8b are connected to the spinal beam of the frame 2 by a pair of braces 11, and the joints of the longitudinal beams 9 and the transverse beams 8 are reinforced with ribs 12 (Fig. 3).
