RU146369U1 - SAND LOCOMOTIVE HOPPER - Google Patents

Abstract

A locomotive sand bunker comprising a bunker body having front, side, rear walls, a lower part, a neck with a hatch, internal elements of lateral stiffness, in the lower part of a pipe for communication with sand system pipelines, characterized in that the front and side walls of the bunker body from a bent metal sheet of a U-shaped shape, the lower part of the hopper body is made of a bent metal sheet-shaped with a horizontal base and inclined walls, internal rigidity elements ovleny vertically between the front and rear walls of the hopper housing.

Description

The utility model relates to rail vehicles, in particular to a locomotive sand feeding system.

A locomotive sandbox bunker is known, its body is made of rectangular segments that are rigidly connected to each other, forming a zigzag shape with at least two bends, and at least two trapezoidal protrusions, at least four stiffeners are installed inside the bends on both sides of the facade which are rigidly fixed and rectangular holes are made in their center, on both sides of which perforation in the form of a “grater” is made, and stiffeners are fixed in one trapezoidal protrusion with it is at least 50 °, and in another - no more than 120 °, (patent RU No. 121212 U1, IPC B61C 15/10, publ. 10/20/2012).

The disadvantage of the design of the well-known sand bunker is the complex construction of the housing (zigzag shape). A large number of zigzags, “graters” increases the complexity of manufacturing the hopper and increases the amount of welding work.

A sand locomotive hopper is known, comprising a hopper body having front, side and rear walls, a lower part and a neck with a hatch made of rectangular sections of a zigzag shape, with internal stiffening ribs and holes in them, internal lateral stiffeners pass through the entire width of the hopper body and installed horizontally or at an angle, in the lower part of the hopper body there is a pipe for communication with the pipeline of the sand supply system (patent RU No. 131352 U1, IPC B61C 15/10, publ. 08/20/2013).

A disadvantage of the construction of the known sand bunker is that the casing of the hopper is made of rectangular sections of a zigzag shape. A large number of zigzags increases the complexity in the manufacture of this design, since an increase in the volume of welding is required.

The technical result of the claimed utility model is to simplify the design of the sand hopper, reduce the complexity of manufacturing by simplifying the design and by reducing the amount of welding work.

-образной формы сThe technical result is achieved by the fact that the sand bunker of the locomotive containing the bunker body having a front, side, rear walls, a lower part, a neck with a hatch, internal stiffeners, in the lower part of the nozzle for communication with pipelines of the sand supply system. The front and side walls of the hopper body are made of bent U-shaped metal sheet, the lower part of the hopper is made of bent metal sheet

-shaped with

horizontal base and inclined walls, internal stiffeners are installed vertically between the front and rear walls of the hopper body.

In FIG. 1 shows a sand bin of a locomotive, front view.

In FIG. 2 shows a sand bin of a locomotive side view.

In FIG. 3 shows a section AA of FIG. one.

-образной формы с горизонтальным основанием 5 и наклонными стенками 6, внутренние элементы жесткости 7 установлены вертикально между передней стенкой 2 и задней стенкой 4. В нижней части корпуса 1 бункера расположены патрубки 8 для связи с трубопроводами системы пескоподачи (на чертеже не показаны). Сверху к корпусу 1 бункера присоединена горловина 9 с люком 10 для заполнения бункера песком.The locomotive’s sand hopper comprises a housing 1 having a front wall 2 and side walls 3 and is made of a bent U-shaped metal sheet, a rear wall 4, a lower part made of a bent metal sheet

-shaped with a horizontal base 5 and inclined walls 6, the internal stiffeners 7 are mounted vertically between the front wall 2 and the rear wall 4. At the bottom of the housing 1 of the hopper there are nozzles 8 for communication with pipelines of the sand supply system (not shown in the drawing). On top of the housing 1 of the hopper attached neck 9 with a hatch 10 to fill the hopper with sand.

The claimed utility model is as follows.

The housing 1 of the sand bunker having a front wall 2 and side walls 3 is made of bent metal sheet U-shaped. The side walls 2 of the housing 1 are connected with the inclined walls 6 of the lower part of the housing 1. Next, the stiffening elements 7 are mounted vertically between the front wall 2 and the rear wall 4. Next, a neck 9 is attached to the housing 1 with a hatch 10. To the base 5 of the lower part the housing 1 of the hopper set nozzles 8.

The sand bunker is filled with sand through the hatch 10, then the sand through the nozzles 8 is fed into the pipelines of the sand supply system.

The use of bent metal sheets in the housing of the sand bunker reduces the complexity by reducing the amount of welding work. Simplification of the design is achieved due to the absence of zigzag elements. The vertical arrangement of the internal stiffeners does not impede the movement of sand in the hopper.

The bunker is planned to be used on new locomotives.
