Description

The utility model relates to rolling stock of railway transport, and in particular to a platform with a loading length of 80 feet, designed for the transportation of large containers, steel pipes, steel long sheet of various sizes, packaged timber cargo.

Currently, the wagon is widely known - platforms designed for the transportation of large containers and long loads (see USSR cars. Industry catalog 20-89-04, Moscow, 1989, pp. 70-75, utility models: RF patent No. 34914, Bull. No. 35, 2003, RF patent No. 46727, Bull. No. 21, 2005, RF patent No. 50495, Bull. No. 2, 2006).

A disadvantage of the known design solutions is their non-universality, insufficient loading capacity of the platforms, insufficient strength and, consequently, the reliability of transportation.

A known construction of a platform car containing a frame with side racks, the extreme of which on each side are paired together, and removable end walls (see EP 0987158 A1, publ. 22.03.2000)

A disadvantage of the known wagon platform is the low reliability due to the removability of the racks and the inefficiency of the distribution of long loads on the frame, which leads to the need

its significant strengthening in the middle part, as well as the use of a large number of double racks increases the metal consumption of the structure.

The closest technical solution to the proposed utility model is a railway platform containing running gears with a frame mounted on them, made of a spinal beam, lateral longitudinal and transverse beams, on which side and corner posts reinforced with stiffeners are rigidly fixed. The side beams of the frame are made of a zeta profile. Corner posts are made of trough-shaped profile. The side shelves of the strut profile have a rectangular cutout at the bottom. According to the height of the racks, inside the box section, sheet elements are installed with an offset relative to the ends of the shelves of the trough-shaped profile. The stiffeners in the lower part of the racks are installed obliquely relative to the longitudinal plane of the car, (see RF patent No. 2207269, Bull. No. 18, 2003)

The main disadvantages of the known technical solution are the high metal consumption, it is impossible to transport metal pipes with a polyethylene coating and other stacked loads due to the possibility of damage, which reduces the functionality of the platform, as well as the inefficiency of using the platform load capacity, non-universality and insufficient structural strength, respectively, and reliability transportation.

The proposed utility model solves the technical problem of increasing the safety of cargo transportation due to the achieved platform strength, increasing the carrying capacity and expanding the platform’s functionality, reducing metal consumption and improving operating conditions due to the convenience of loading and unloading.

To achieve the technical result, a railway platform containing a running gear, a brake system and a supporting frame, which includes a spinal beam, side, pivot, frontal, transverse and intermediate beams, on which the side and corner posts are rigidly fixed, and between the frontal and pivot braces are installed on the beams, it is additionally equipped with end walls rigidly fixed to the frontal beams, side walls and high-speed rope tensioning mechanisms mounted on racks, side walls are mounted on the console parts of the platform, which are rigidly fixed to the side beams and end walls, while the side and end walls are interconnected by beam connections, and the spinal beam is made of two I-beams of variable cross-section, the I-beams of which are made with cuts along the axis of symmetry and rigidly interconnected by inserts made of perforated sheets, while the side beams and side walls are also made perforated.

Trimming and bending of the lower parts of the I-beams in the spinal beam and the extreme parts of the inserts are made at an angle to the horizontal.

Hinged frames are mounted on the side beams of the platform frame, and removable stops for installing containers on the front beams.

End, side walls and side racks from the side of the internal loading aperture of the platform are equipped with elements for protecting the cargo from damage.

At the same time, in the middle part of the platform, lodges are fixed to the frame beams, in which wooden blocks are laid and rigidly fixed, and in

the console part of the platform is wooden blocks - directly to the frame beams.

The essence of the proposed technical solution is illustrated by drawings, where the figures shown:

- figure 1 is a General view of a railway platform;

- figure 2 is the same, a top view;

- figure 3 - frame platform;

- figure 4 - side (right and left) wall of the platform;

- figure 5 - railway platform - installation of stops for securing containers;

- 6 - railway platform - installation of equipment for the transport of pipes and strip;

- Fig.7 - railway platform - installation of a high-speed rope tensioning mechanism.

The railway platform (Fig.1, 2) contains the chassis 1, the brake system 2 and the supporting frame 3. The supporting frame 3 includes a spinal beam 4, side 5, pivot 6, frontal 7, transverse 8 and intermediate 9 beams. On the side beams 5, the side 10 and corner 11 racks are rigidly fixed, which are reinforced with stiffeners 12. There are braces 13 between the frontal 7 and pivot 6 beams.

Bearing frame 3 (figure 3) takes the load of the transported goods, traction, impacts in automatic couplings, inertial forces from changes in the speed of the rolling stock.

Frontal beams 7 connect the spinal 4 and two lateral 5 beams, the latter made of an I-beam.

All the supporting elements of the frame 3 of the platform are rigidly interconnected by welding. Pivot 6, transverse 8 beams are box-shaped.

The composition of the railway platform introduced end 14 and side walls 15 (Fig.1, 4, 6). The end walls 14 are rigidly fixed to the frontal beams 7, and the side walls 15 are installed in the cantilever part of the platform and are rigidly fixed to the side beams 5 and the end walls 14. In this case, the side 15 and end walls 14 are interconnected via beam connections 16.

The spinal beam 4 (Fig. 3) is the main load-bearing element that perceives loads, both dynamic during the movement of the train, and static from the mass of the load, and it is made of two I-beams of variable cross-section. I-beams of the spinal beam 4 are made with cuts along the axis of symmetry and are rigidly interconnected by inserts 17 made of perforated sheets.

The implementation of the I-beams of the spinal beam 4 with inserts 17 (figure 3) allowed to increase the cross-sectional area and, as a consequence, the strength of the platform and, accordingly, to increase its load capacity. By calculation and experimentally, the optimal thickness of the insert 17 in the spinal beam 4 was determined, when the thickness of the insert 17 is less than 10 mm, the necessary platform strength is not provided, and when the thickness of the insert 17 is more than 12 mm, the metal consumption increases and, accordingly, an unjustified increase in the tare weight of the car which leads to an increase in cost and deterioration of the commercial properties of the platform.

Trimming and bending of the lower parts of the I-beams in the spinal beam 4 and the extreme parts of the inserts 17 are made at an angle to the horizontal.

Thanks to the implementation of the angles of trimming and bending of the lower parts of the I-beams, a smooth transition through the cross section in the spinal beam

4, which leads to a decrease in stresses arising in the spinal beam 4, as in one of the main supporting elements of the platform.

One of the best options is the height of the spinal beam 4 in the cantilever part due to trimming is 380 mm, and in the middle part due to inserts 17 of perforated sheets, the cross-sectional height is 950 mm.

To reduce the metal consumption, the side beams 5 and the side walls 15 of the railway platform are perforated.

To expand the functionality of the platform on the side beams 5 of the frame 3 of the platform, hinged 18 are mounted, and on the frontal - removable 19 stops for installing containers (Fig. 5).

The stops 18, 19 serve to install containers on the platform and prevent containers from moving relative to the platform during transportation. The design of the folding 18 stops allows you to install containers on the platform with a loading length of 20 and 40 feet with a total loading length of 80 feet in various combinations.

Equipment platform for transporting pipes and sheets of metal (Fig.6) consists of two end 14, two right and two left side 15 walls, eight racks 10, 11 on each side beam 5.

End 14, side 15 walls and side racks 10 on the side of the internal loading opening of the platform are equipped with elements for protecting cargo 20 from damage, which can be used rubber gaskets to ensure the safety of protective coatings of transported goods.

In the middle part of the platform, rails 21 are fixed to the beams of the frame 3, in which wooden blocks 22 are laid and rigidly fixed. In the console part of the platform, the wooden bars 22 are rigidly fixed directly to the beams of the frame 3.

In the proposed railway platform, the side 10 and corner 11 racks are equipped with high-speed rope tensioning mechanisms

23 for tying pipes, packaged timber cargo (Fig.7). The rope 24 covers the transported cargo and due to the movement of the fork 25 in the bearings 25 around the axis 27 through the dead center and the comb 28, the tension of the rope 24 occurs. 24 is carried out on the bracket 30.

Loading onto the platform of containers, pipes and sheets of metal is carried out in accordance with the instruction manual for railway platforms of this class.

The increase in the cross section of the spinal beam 4 allowed to significantly increase the payload on the platform frame and provided the opportunity to increase the carrying capacity of the platform car.

It should be noted that the entire set of design solutions used in the proposed utility model, due to the achieved platform strength, increased load capacity, expanded the functionality of the railway platform and improved traffic safety conditions.

As a result of the universality of the proposed design of the railway platform, it became possible both to transport large-capacity containers with their various combinations, and to transport steel welded pipes with an external polyethylene coating and without covering an unmeasured length, a steel long sheet of various sizes, packaged timber cargoes that do not require protection against atmospheric precipitation loading length of 80 feet.

Using the proposed design of the utility model allows to increase the carrying capacity compared with existing models

platforms, to increase the safety and reliability of cargo transportation by increasing the strength of the platform design, to improve consumer qualities and commercial properties of the railway platform by expanding the functionality and efficiency of cargo handling.
