Description

The utility model relates to the field of railway transport, in particular, to the frame of a railway platform for the transportation of large-tonnage containers.

Known rail platform frame, containing side beams, center beam, end beams, pivot beams and intermediate cross beams. Moreover, the pivot, end and intermediate cross beams connect the side beams with the center beam and lie in the same plane, which forms the plane of the frame. Each side beam is a profile, the upper part of which protrudes above the plane of the frame (RU No. 46727, IPC B61F 1/02, B60P 3/40, publ. 27.07.2005).

The disadvantage of the known solution is insufficient strength and rigidity, as well as high metal consumption of the platform frame.

Known platform car frame, which includes a center beam having a box section, which includes two vertical sheets. The frame also includes two side beams running longitudinally with respect to the center beam, cross beams installed across the center beam, while the cross beams have a cross section composed of a vertical wall, an upper horizontal flange and a lower flange, which in the area between the center beam and the side the girder is located obliquely, and in the area between the vertical sheets of the backbone girder it is located horizontally inside it. The lower flange of the crossbeam, located between the vertical sheets of the center beam inside it, is located at a distance from the bottom flange of the center beam in the range from 70 to 180 mm, forming a horizontal bridge inside the center beam between its vertical sheets, and the lower the shelf has a constant width along its length (RU No. 171768, IPC B61D 3/00, B61F 1/00, publ. 06/15/2017).

The disadvantage of the known solution is insufficient strength and rigidity, as well as high metal consumption of the platform frame.

The closest technical solution to the claimed one is the frame of a railway vehicle, containing a center beam with fixed front and rear stops, a set of side and cross beams, pivot and end beams made of sheets, braces, characterized in that the center beam of the frame is made P- shaped profile, the top sheet of which is made thinner than the bottom sheets, while the top sheet and the bottom sheets in the area between the pivot beams are made of variable width. (RU No. 40974, IPC B61F 1/02, B61F 1/08, publ. 10.10.2004).

The disadvantage of the closest technical solution is the insufficient strength of the frame, since the configuration of the bottom sheet of the pivot girder does not provide the necessary rigidity (the angle of inclination of the middle part of the bottom sheet of the pivot girder is less than 20 °).

The technical problem solved by the utility model is the insufficient strength of the pivot girder of the railway platform frame.

The technical result of the proposed solution is to increase the reliability of the frame by changing the configuration of the bottom sheet of the pivot beam.

The technical result is achieved by the fact that the frame of the railway platform consists of two consoles connected to the bearing side beams by pivot beams. The load-bearing side beams are interconnected by transverse connecting beams. The frame console of the railway platform consists of a longitudinal beam, braces and a crossbeam. The bearing side beams and the console are interconnected by a pivot beam, the upper and lower sheets of which are made end-to-end with the protrusions of the upper sheet and the lower sheet of the longitudinal beam, respectively, and with the protrusions of the upper sheet and the lower sheet of the side beam, respectively. The bearing side beams and the console are interconnected by an end beam, the upper and lower sheets of which are made end-to-end with the protrusions of the upper sheet and the lower sheet of the longitudinal beam, respectively, and with the protrusions of the upper sheet and the lower sheet of the side beam, respectively. Each bottom sheet of the pivot beam is made of one bent sheet and contains an outer part adjacent to the side beam, a middle inclined part and an inner part adjacent to the longitudinal beam. The angle of inclination of the middle inclined part of the sheet of the lower pivot beam is in the range β = 20 ... 30 °. The top sheets, the outer and inner parts of each bottom sheet of the pivot girder are made in parallel.

The pivot and end beams connect the bearing side beams with the consoles, the braces and transverse beams of the consoles are connected to the side beams, while the upper sheets of the consoles, pivot, end and side beams are located in one plane, which forms the upper surface of the frame.

The frame of the railway platform for the transportation of large-tonnage containers (Fig. 1) is made of long wheelbase and consists of two consoles 1 connected to the load-bearing side beams 2 by pivot beams 3. The load-bearing side beams 2 are interconnected by transverse connecting beams 4. At the frame corners on the end beams 5 U-shaped section, which is the closing link of the frame, stationary fitting stops are rigidly fixed (conventionally not shown in the drawings). On the bearing side beams 2 there are hinged fitting stops (conventionally not shown in the drawings) for installing and securing containers.

The console 1 of the railway platform frame (Fig. 2) consists of a longitudinal beam 6, braces 7 and a transverse beam 8.

The side beam contains upper 12 and lower 13 sheets (shelves) and a vertical 14 sheet (wall) (Fig. 5).

The bearing side beams 2 and the console 1 are interconnected by a pivot beam 3 (Fig. 1), the upper 16 and lower 17 sheets of which are made end-to-end with the protrusions 11 of the upper sheet 10 and the lower sheet 9 of the longitudinal beam 6 and with the protrusions 15 of the upper sheet 12 and the lower sheet 13 of the side beams 2, respectively (Fig. 3).

Each bottom sheet 17 of the pivot beam 3 is made of one bent sheet and contains an outer part 17.1 adjacent to the side beam, a middle inclined part 17.2 and an inner part 17.3 adjacent to a longitudinal beam 6. The angle of inclination of the middle inclined part 17.2 of the sheet of the lower 17 pivot beam 3 is in the range β = 20 ... 30 ° (Fig. 3). The angle of inclination of the middle inclined part 17.2 less than 20 ° reduces the rigidity of the structure, the angle of inclination of more than 30 ° leads to an increase in metal consumption and a decrease in the carrying capacity of the car. The top sheets 16, the outer and inner parts of each bottom sheet 17 of the pivot beam 3 are made in parallel (Fig. 3).

The end beam contains upper 18 and lower 19 sheets (shelves) and a vertical 20 sheet (wall) (Fig. 5-6).

The bearing side beams 2 and the console 1 are interconnected by an end beam 5 (Fig. 1), the upper 18 and lower 19 sheets of which are made end-to-end with the protrusions 11 of the upper sheet 10 and the lower sheet 9 of the longitudinal beam 6 and with the protrusions 15 of the upper sheet 12 and the lower sheet 13 of the side beam 2, respectively (Fig. 4), thereby increasing the fatigue resistance coefficient at the joints.

Pivot 3, end 5 beams connect bearing side 2 beams with consoles 1, braces 7 and transverse beams 8 of consoles 1 are connected to side beams 2, while the top sheets of consoles 1, pivot 3, end 5 and side 2 beams are located in the same plane, which forms the top surface of the frame.

Experimental operation and subsequent tests showed that changing the configuration of the lower sheet of the frontal beam led to an increase in the strength of the frontal beam, which, accordingly, increased the reliability of the frame.
