Abstract

The utility model relates to the rolling stock of railway transport, namely to platforms for transporting cars, caravans, semi-trailers involved in piggyback transportation. The railway platform contains a supporting frame (1) mounted on bogies (2). A rotary cargo platform (3) is installed on the supporting frame (1). The rotary cargo platform (3) in its middle part is equipped with fastening grips made in the form of installed drive handles (4) rigidly fixed to the shafts (5), a hook-hook (5.1) is rigidly fixed on each drive shaft (5), designed for connections with a locking pin (6) fixed to the base frame (1). The interconnection in the middle of the supporting frame (1) with the rotating cargo platform (3) allows to increase the total cross-section of the supporting frames of the railway platform for piggyback transportation. This makes it possible to achieve the declared technical result - an increase in the rigidity and strength of the railway platform for piggyback transportation. 1 wp f-ly, 4 dwg.

Description

The utility model refers to the rolling stock of railway transport, namely to a platform designed for the transportation of cars, trailers, semi-trailers involved in piggyback transportation.

It is known a railway vehicle comprising a supporting frame mounted on bogies, a rotary cargo platform mounted on a supporting frame with the possibility of rotation in a horizontal plane, see WO 9107301, B61D 3/18. publ. 05/30/1991.

It is also known a railway vehicle containing a supporting frame mounted on bogies, a rotary cargo platform mounted on the supporting frame with the possibility of rotation in a horizontal plane, see RU 2440262, B61D 3/18. publ. 01/20/2012 (prototype).

A common technical problem typical for these devices is the lack of the possibility of attaching the supporting frame and the rotating cargo platform in their middle part to each other, which negatively affects the overall rigidity of the railway platform for piggyback transportation.

The technical result of the claimed utility model is to increase the rigidity and strength of the railway platform for piggyback transportation.

The specified technical result is achieved by a railway platform for piggyback transportation, containing a supporting frame mounted on bogies, a rotary cargo platform is installed on the supporting frame with the ability to rotate in a horizontal plane, the rotary cargo platform is equipped in its middle part with fastening grips for rigid connection with the supporting frame, located on the lateral sides of the rotary cargo platform, the fastening grips are made in the form of drive handles rigidly fixed on the shafts, the shafts are installed with the possibility of pivoting in the holes of the cargo platform frame, a hook-hook is rigidly fixed on each drive shaft, designed to interact with the counter-locking pin, fixed to the supporting frame; The locking pin can be installed at its ends in a mounting bracket fixed to the base frame.

The claimed utility model differs from the prototype in that the rotary cargo platform in its middle part is equipped with fastening grips for its rigid connection with the supporting frame, located on the sides of the rotary cargo platform, the fastening grips are made in the form of drive handles rigidly fixed to the shafts, the shafts are installed with the possibility of rotation in the openings of the cargo platform frame, a hook-hook is rigidly fixed on each drive shaft, designed to interact with a counter-locking pin attached to the supporting frame; the fixing pin is installed at its ends in a mounting bracket fixed to the supporting frame. Such differences from the prototype give grounds to assert that the proposed technical solution meets the criterion of patentability of a utility model - “novelty”.

The utility model is shown in the drawings, where:

in fig. 1 - railway platform for piggyback transportation, general view;

in fig. 2 - remote element "A" in Fig. 1;

in fig. 3 - fastening grip, local view, isometric projection;

in fig. 4 - the same, local section, isometric view.

The railway platform for piggyback transportation contains a supporting frame 1 (Fig. 1). The supporting frame 1 is installed on the undercarriage 2. On the supporting frame 1, a rotary cargo platform 3 is installed with the ability to rotate in the horizontal plane.

For a rigid connection with the supporting frame 1, the rotary cargo platform 3 in its middle part is equipped with fastening grips located on the lateral sides of the rotary cargo platform 3 (Figs. 2, 3). The fastening grips are made in the form of 3 drive arms 4 installed on the rotary cargo platform, rigidly fixed on the shafts 5. The shafts 5 are installed with the possibility of rotation in the frame holes 3.1 of the rotary cargo platform 3. On each drive shaft 5, a hook-hook 5.1 is rigidly fixed, intended for interaction with the fixing pin 6, fixed on the supporting frame 1 (Fig. 4).

The fixing pin 6 can be installed at its ends in the mounting bracket 7, fixed on the supporting frame 1.

The technical result, which consists in increasing the rigidity and strength of the railway platform for piggyback transportation, is achieved as follows.

Loading and unloading operations are carried out with uncoupled fastening grips. After the completion of loading and unloading operations and before starting the movement, the bearing frame 1 is interconnected with the rotary cargo platform 3. For this, the shaft 5 is rotated by the drive handle 4, which, while rotating, engages the hook-hook 5.1 with the fixing pin 6, rigidly connecting the rotary load platform 3 and carrying frame 1. Similarly, all other fastening clamps are connected. The connection of the hooks 5.1 with the fixing pins 6 creates rigid connections between the supporting frame 1 with the rotary cargo platform 3, forming a single strong and rigid structure. To disengage the fastening grips, turn the drive handle 4 in the opposite direction, while the hook-to-eye 5.1 is disconnected from the fixing pin 6.

The interconnection of the supporting frame 1 with the rotating cargo platform 3 in its middle part allows to increase the total cross-section of the supporting frame 1 and the frame of the rotating cargo platform 3. This allows achieving the claimed technical result - increasing the strength and rigidity of the railway platform for piggyback transportation.
