LT6646B - Platform car for transport of road semi-trailers and large-capacity containers - Google Patents

Abstract

The invention relates to a railway rolling stock, namely freight railway wagons for the transport of road semi-trailers and large-capacity containers. Platform car comprises the chassis (1), coupler equipment (2), a brake system (3) and the supporting frame (4) which includes a center beam (5), the side beam (6), the pivot beam (7), frontal beam ( 8), the cross beam (9), and saddle device (11) for locking the kingpin of the semitrailer, fitting stops (12,13) for mounting of containers. Thus the beam (5) of the supporting frame (4) platform car consists of two parts placed in the parts of the console of the car, and in the space frame between bogies positioned cart (14) having a lower floor level for transporting semitrailers on the wagon within railcar envelope 1- T. Side beam (6) of the platform car is designed as a variable height of the box section. Additional cross-beams (10) are used for sensing longitudinal loads in collisions. Wherein the saddle device (11) has a slight adjustment in the longitudinal direction and the possibility of adjustment in the transverse direction to compensate for distortions of the semitrailer during loading.

Description

The invention relates to rolling stock, namely freight wagons-platforms for transporting semi-trailers and high-capacity containers.

There is known a collapsed wagon-platform for combined transport, the carrier frames of which are lowered into the deep space between the bogies, and are provided with longitudinal side carrier walls, on which are attached additional middle base supports for container fastening, Russian patent no. 176836, B61D 3/10, B61F 1/00, publ. 01/30/2018.

The disadvantage of this wagon-platform design is its narrow application, since the design does not allow for the loading of semi-trailers without special grooves ("pockets") on the frame to be hooked up by means of load lifting devices (cranes, forklifts, spreaders). ). It is also necessary to lock the wheels of the semi-trailer with the wheel brakes, which increases the loading time and complicates it.

The closest technical solution to the claimed wagon-platform is a prototype railroad platform, which includes a frame mounted on a bogie, a support for a semi-trailer saddle platform with longitudinal movement, a rotating loading bay and a block for locking the wheels of a semi-trailer, Russian patent. 125151, B61D47 / 00, B61D 3/18, publ. 2/27/2013

The disadvantages of this railway platform are:

1. Special infrastructure is required (loading terminals with a maximum platform difference of 100 mm between the platform and the terminal) for loading the semi-trailer.

2. The transport of a railway platform with a semi-trailer mounted on it may only take place at a specific loading size, with limited range of movement, due to the high level of the loading bay in relation to the upper surface of the railheads.

3. Limited range of transportable standard size containers, as they do not have fitting supports that allow the transport of 1CC size containers.

The technical result of the claimed invention is to expand the range of goods being transported, to improve working conditions, by reducing the time and complexity of loading and unloading semi-trailers for vehicles, and to transport a semi-trailer with a 1-T gauge wagon.

This technical result is achieved by the fact that the wagon-platform for transporting semi-trailers and heavy containers includes chassis, automatic clutch equipment, braking system and support frame which includes protruding beam, side, pivot, front, transverse beams, semi-trailer pivot. for fastening, fitting supports for container mounting. At the same time, the protruding beam of the wagon-platform frame consists of two parts housed in the wagon console parts, resulting in a free space between the bogies with a basket for loading and transporting standard mass-produced semi-trailers (not having special grooves on the frame devices) and having a lowered floor, for the transport of semi-trailers on a wagon up to a size of 1-T, which allows the wheels of the semi-trailer to be fitted without wheel supports. The wagon-platform side beam has the shape of a variable-height box cross-section, and additional transverse beams help withstand longitudinal loads during collisions. The saddle unit has smooth longitudinal adjustment and transverse adjustment to compensate for the semi-trailer curvature during loading.

In some cases, the wagon-platform fittings are mounted on the brackets. This allows transportation of high capacity containers without removing or pushing the saddle unit. At the same time, the fitting supports for securing containers of size 1CC located in the middle part of the wagon are made with the possibility of hinging on the outside of the wagon and locking in the open position with spring-loaded semi-automatic latches.

The present invention is illustrated by a graph, wherein: FIG. a general view of the wagon-platform with the semi-trailer mounted; Figure 2 Empty wagon-platform view Figure 3 - wagon-platform frame; Figure 4 fitting supports in the middle part of the wagon-platform.

The wagon platform of car semi-trailers and heavy containers includes chassis 1 (Figs. 1, 2), automatic clutch equipment 2, braking system 3 and support frame 4. Frame 4 includes protruding beam 5 (fig. 3), side beams 6, pivot beams. 7, front beams 8, transverse beams 9, auxiliary transverse beams 10, saddle assembly 11 for securing a semi-trailer pivot, and fitting supports 12, 13 for mounting containers. In the wagon-platform frame 4, a basket 14 is placed between the bogies (Fig. 2). The clamping supports 12, 13 (Fig. 3) are mounted on the brackets 15, in addition, the clamping supports 13 (Fig. 4), located in the middle part of the wagon, have a hinged outward opening and are locked in the open position by spring-loaded semi-automatic latches 16.

Using this wagon-platform as a vehicle for transporting semi-trailers, the folding supports 13 are folded to the outside of the wagon and secured by semi-automatic spring latches 16, the vehicle semi-trailer is, for example, placed in a basket 14 on the ground using, for example, a load lifting crane (not shown), a basket with a mounted semi-trailer places the free space between the bogies of the frame 4 against the lateral beams 6, at which time the semi-trailer pivot is locked by the saddle device 11 to prevent vertical movement; by securing against all displacements by lowering them into special slots in the basket 14 and securing the basket against longitudinal displacements by means of additional transverse beams 10.

When using this wagon-platform as container transport, the fitting supports 12,13 are used, in addition, the fitting supports 13 must be folded into their working position before use. When using a crane (not shown), performs the installation of containers on the fitting supports 12.13. The platform wagon for transporting semi-trailers and large containers is ready for use.

Industrial applicability.

The claimed technical solution is implemented using industrially manufactured equipment and materials and can be produced by any wagon construction company and will be widely applied in the field of rail transport.
