Abstract

FIELD: railway rolling stock; timber carriers.

SUBSTANCE: proposed flat-car body contains frame 1 with box-section side posts connected with side braces made in form of S-shaped members 2 by means of rigid nondetachable coupling. Lower parts of posts, starting from end face, have cross section increasing in height, side walls 5 square to longitudinal axis of car of all or part of posts project relative to inner wall o6 of post. Diaphragms 10 welded to lower surface of upper sheet and to vertical walls are located under zones of horizontal welds connecting inner wall of posts, except for extreme twin posts, to upper sheet of cross beams inside the beams. Plate compensators 8 are installed in place of interaction of lower end face of posts with lower flange of s-shaped member 2.

Description

The invention relates to railway rolling stock and relates to the bodies of platform wagons intended for the transportation of mainly timber.

A well-known platform for woods and whips, model 23-925, manufactured by Stakhanovsky “Carriage Building”, whose body is a powerful welded structure with removable equipment for transporting wood. Each section of removable equipment is made of three powerful racks of box-section, interconnected by transverse beams [1].

The disadvantage of this design is the high metal consumption and an overestimated center of gravity due to the use of additional transverse beams in sections of removable equipment for transporting timber.

Known platform model 23-469 Dneprodzerzhinsky Carriage Works, designed to transport timber in whips.

The platform car body has a powerful frame with twelve fixed metal racks (six on each side). Fixed racks include L-shaped brackets with a swing mechanism. The side beams of the platform frame are made of I-beam No. 55B of variable height along the length. Side racks have a box section, decreasing upwards, and are attached using shaped stiffeners [2].

-образных элементов, жесткой неразъемной связью. Вагон-платформа может изготавливаться как со съемными торцевыми стенами, так и без них [3].Known wagon platform containing a frame with side racks of box-shaped cross section associated with side strands made in the form

-shaped elements, rigid one-piece connection. A platform car can be made both with removable end walls and without them [3].

-образного элемента, расположен в одной плоскости с ее кромкой, а боковые стенки стоек, перпендикулярные продольной оси вагона, выполнены заподлицо с внутренней стенкой стойки.In the back of this platform, the bottom end of the rack welded to the bottom shelf

-shaped element, is located in the same plane with its edge, and the side walls of the racks, perpendicular to the longitudinal axis of the car, are flush with the inner wall of the rack.

This design is selected as the closest analogue.

The main disadvantages of the analogue are:

-образного элемента из-за наличия на последней радиуса округления до 10 мм и при неблагоприятном сочетании допусков на сопрягаемые детали образуется большой зазор, который ведет к некачественному их соединению (приварке), что значительно снижает прочность заделки стоек от распорных нагрузок;- when assembling the lower end of the rack with the lower shelf

-shaped element due to the presence on the last radius of rounding of up to 10 mm and with an unfavorable combination of tolerances on the mating parts, a large gap is formed, which leads to poor-quality connection (welding), which significantly reduces the strength of sealing racks from spacer loads;

- the connection of the side walls of the racks, perpendicular to the longitudinal axis of the car, flush with the inner wall forms a smooth surface near the rack, which does not create resistance to the movement of timber during longitudinal shock loads;

- the inner walls of the struts are welded to the upper surface of the upper sheets of the transverse beams with a horizontal seam parallel to the longitudinal axis of the car.

In this case, under the action of spacer loads, the horizontal seam mainly works, and the cross-section of the transverse beam in the weld zone is not included in the work.

The problem to which the present invention is directed, consists in increasing the strength of the fastening of the uprights, increasing the manufacturability of their connection, as well as creating resistance to the movement of timber along the platform under the action of longitudinal shock loads.

-образного элемента к вертикальной стенке).The problem is solved in that the lower parts of the racks, starting from the end, are made with a cross-section increasing in height, which makes it possible to exclude increased gaps at the junction (move the lower part of the rack from the rounding radius on the shelf

-shaped element to a vertical wall).

This technical solution also allows you to install lining - joints in joints.

The lateral sides of the walls perpendicular to the longitudinal axis of the car, all or part of the racks are made protruding relative to the inner wall.

In addition, in order to more efficiently enable horizontal welds to weld the internal walls of the struts (except for the extreme twin) to the top sheet of transverse beams, as well as the sections of the beams themselves, under the weld areas, inside the transverse beams, diaphragms are installed, welded to the bottom surface of the top sheet and to the vertical walls.

-образных элементов, жесткой неразъемной связью, нижние части стоек, начиная от торца, выполнены с увеличивающимися по высоте поперечным сечением, боковые стены стоек, перпендикулярные продольной оси вагона, всех или части стоек выступают относительно внутренней стенки стойки, а под зонами расположения горизонтальных швов приварки внутренних стенок стоек (кроме крайних сдвоенных) к верхнему листу поперечных балок внутри последних установлены диафрагмы, приваренные к нижней поверхности верхнего листа и к вертикальным стенкам.The essence of the invention lies in the fact that in the body of a platform car containing a frame with side racks of box-shaped cross-section, connected with its side strands, made in the form

-shaped elements, rigid one-piece connection, the lower parts of the racks, starting from the end, are made with increasing cross-sectional height, the side walls of the racks perpendicular to the longitudinal axis of the car, all or part of the racks protrude relative to the inner wall of the rack, and under the zones of horizontal welds The inner walls of the uprights (except for the extreme twin ones) have diaphragms welded to the lower surface of the upper sheet and to the vertical walls to the upper sheet of transverse beams inside the latter.

-shaped elements can be installed compensators in the form of plates.

The essence of the invention is explained in more detail with reference to the accompanying drawing, showing an example of the structural design of the body of a freight car.

-shaped element 2 can be installed compensators 8 in the form of plates. Under the zones of horizontal welds of the inner walls of the 6 racks (except for the extreme double ones), diaphragms 10 are installed on the upper sheet 9 of the transverse beams, welded to the lower surface of the sheet 9 and to the vertical walls 11.

The technical result of the present invention is expressed in increasing the strength of the connection of the uprights with the frame of the car and in creating resistance to the movement of timber during longitudinal shock loads.

Currently, working drawings have been developed on a platform car with the proposed bodywork and production is being prepared for the manufacture of the installation lot.
