Description

The invention relates to the field of railway transport, in particular to platform wagons for the transportation of long loads, mainly pipes, sheet metal, lumber and timber.

Known designs of flatcars for the transport of long loads (see RU No. 2270114 C2, B61D 3/08, B61D 3/20, 02/20/2006; RU No. 2007317 C1, B61D 3/08, 02/15/1994; RU No. 2236964 C2, B61D 3/08, 17/00, 09/27/2004; RU No. 2207269 C2, B61D 3/08, B61F 1/00, 06/27/2003; RU No. 2262458 C1, B61F 1/00, 10/20/2005; RU 2288121 C1, B61D 3/20, B61F 1/02, 11/27/2006; RU No. 53992 U1, B61D 3/08, 06/10/2006; RU No. 25720 U1, B61D 3/08, 10/20/2002; RU No. 61232 U1, B61D 3 / 08, B61F 1/00, 02/27/07).

The disadvantage of these designs is their high metal consumption.

The closest technical solution to the claimed invention is the design of a flatcar according to patent UA No. 28027 U, B61D 3/08, 11/26/2007, which contains a supporting frame mounted on two biaxial bogies, on the end beams of which are placed flat bases, protruding beyond the borders of the frame, the parts of which are fixedly fixed, end walls with flat side reinforcements reinforced by braces on the outside, racks installed in pairs on the side beams, glasses of forest racks and rings for securing the load, a protective casing, above which rise the lodgements located between the opposite uprights and in the spaces between them, shortened spinal beams installed below the side and end beams, brake and coupler devices.

A disadvantage of the known platform car is the high metal consumption and, consequently, insufficient carrying capacity.

In addition, the protective casing does not allow the accumulation of accumulated moisture and dirt from the surface of the platform car, which complicates its maintenance and operation.

The technical result of the claimed invention is to increase the carrying capacity of the car by reducing its tare, improving its service and operating conditions.

The specified technical result is achieved by the fact that in the flat carriage containing the supporting frame mounted on two biaxial bogies, on the end beams of which are flat bases, on the parts of the protruding beyond the frame which end walls are fixedly fixed with flat side reinforcements reinforced from the outside braces, racks installed in pairs on the side beams, glasses of forest racks and rings for securing the cargo, a protective casing over which lodges rise between the opposite with struts and in the intervals between them, shortened spinal beams installed below the side and end beams, brake and coupler devices, the following distinctive features are provided: side beams are made of two cantilevered and one middle parts rigidly interconnected, made of welded I-beams with different wall thicknesses in the cantilever and middle parts, the inner surface of the side racks located above the frame is in the same plane with the outer edges of the shelves of the side beam or beyond and, the protective casing is fixed to the pivot, end and intermediate transverse beams, has slopes towards the side beams of the frame and is below their upper plane, while a gap is provided between its side edges and the walls of the side beams.

The braces of the flat side reinforcements of the end walls are fixed on the outer surfaces of the side beams of the frame.

Each side pillar is connected to the upper shelf of the side beam and the base mounted on the shelves and the wall of the side beam.

Glasses of forest racks are installed in pairs on the side beams of the frame and are rigidly connected to their walls and upper shelves, while the extreme of them are located between the pivot and end beams, the rest at the ends of the transverse beams.

The rings for securing the cargo are fastened to the walls and upper shelves of the side beams of the frame, while two of them, located in the middle of the platform car, are installed on the upper surface of the side beams.

Each side stand is equipped with a ladder, the steps of which are welded to the stand at one end and the bow to the other.

The proposed solution is illustrated by drawings, where:

The proposed wagon platform consists of a supporting frame 1 mounted on two biaxial trolleys 2, brake 3 and couplings 4. On the end beams 5 of the frame, flat bases 6 are installed, parts of which protrude beyond the frame in the longitudinal direction. On the protruding parts 7 of the base 6, the end walls 8 are fixedly fixed with flat lateral reinforcements 9, the outer surface of which is reinforced with braces 10. The frame 1 also contains side 11, shortened spinal 12, pivot 13 and transverse 15 beams connected to a single supporting metal structure.

The longitudinal forces are transmitted from the coupler 4 to the side beams 11 through the braces 16 connecting them to the shortened spinal beams 12. The shortened spinal beams are installed below the side 11 and end 5 beams. Side beams are made of rigidly interconnected two cantilever 17 and one middle 18 parts made of welded I-beams. The wall thickness S of the I-beam in the middle part 18 differs from the wall thickness S ₁ in the cantilever parts. The length L of the cantilever parts and the length L _{1 of the} middle part of the frame are in the ratio L / L ₁ = 0.85 ... 0.95, which for different thicknesses S and S _{1 of the} walls of the side beams provides the necessary strength of the frame in all sections. Racks 19 are installed in pairs on the side beams 11. Each rack is connected to the upper shelf 20 of the side beam and the base 21, mounted on the wall and shelves of the side beam. In the embodiment of FIG. 5, embodiment 1, this connection is made at the upper shelf 20. In the embodiment 2 of FIG. 6, the base 21 is fixed to the wall and the upper shelf of the side beam. In the installed racks, the inner surface 22 is in the same plane with the outer edges 23, 24 of the side beam or beyond. Each rack is equipped with a ladder 25, the steps 26 of which are welded to the rack at one end and the string 27 at the other, the ends of which are bent and welded to the rack. On the transverse beams 15 located between the pairs of uprights 19, as well as on the middle 28 of these beams located between the first and second, third and fourth pairs of uprights, lodges 29 are installed that rise above the surface of the frame 1. The frame is equipped with a protective casing 30, above with which the lodgements rise. The casing is mounted on pivot 13, end 5 and transverse 15 beams. At the same time, slopes are made in it towards the side beams 11. The top of the casing is located below the upper plane of the frame, and a gap “α” is provided between its side edges and the walls of the side beams 11. The slopes in the sides of the side beams and the clearance “α” contribute to better drainage of moisture and dirt from the surface of the protective casing, improving the service and operating conditions of the flat car. In addition, a protective cover protects the transported cargo from below from dust and dirt.

The braces 10 of the flat side reinforcements 9 of the end walls 8 are fixed on the outer surfaces of the side beams 11 of the frame. To ensure ease of connection with the frame and its strength in these places between the shelves of the side beams installed U-shaped profiles 31.

On the side beams 11, one pair of opposed beams are mounted and rigidly connected to the walls and upper shelves of the forest racks 32. The extreme of them are located between the pivot 13 and the end 5 of the frame beams, the rest at the ends of the transverse beams 15. The location and number of them ensures reliable fastening and transportation of saw and timber.

The load securing rings 33 provide uniform fastening of sheet metal products along the entire length of the flat car. They are fastened to the walls and upper shelves of the side beams 11 of the frame, and two of them, located in the middle of the platform car, are fixed on the upper surface of the side beams.

The proposed design of the platform car allows you to reduce the width of the frame, reduce its weight and the tare of the platform car, and, therefore, its load capacity, prevent the accumulation of moisture and dirt on the surface of the protective casing and improve its service and operating conditions of the platform car.

The prototype made according to the claimed technical solution successfully passed all types of tests and preparations are underway for its mass production.
