Description

The claimed utility model relates to rail vehicles, in particular to railway cargo platforms for the transportation of large-capacity containers.

Known railway platform for large-capacity containers containing installed on the undercarriage frame with end beams, see EN 2475389, B61D 3/00, B61D 3/20, publ. 02/20/2013.

The technical problem inherent in this railway platform is the low operational reliability caused by the lack of latches for the end doors of large-capacity containers transported on the platform, leading to their possible unauthorized opening.

A railway platform for the transportation of large-capacity containers, model 13-6954, is also known, containing a frame with end beams installed on undercarriages, locks-stops installed on the frame to prevent opening of the end doors of large-capacity containers during their transportation, see "Transmash holding", see resource http://scaletrainsclub.com/board/viewtopic.php?style=7&f=46&t=13816.

The technical problem inherent in this railway platform is also low operational reliability, due to the need for additional manual operations to bring the lock-stops both into working state and into non-working state, which consists in manually raising the thrust frame, its forced connection with the fixing rod.

The technical result of the claimed utility model is to increase the operational reliability of a railway platform for the transportation of large-capacity containers.

The specified technical result is provided by a railway platform for the transportation of large-capacity containers, containing a frame with end beams installed on undercarriages, locks-stops installed on the frame to prevent opening of the end doors of large-capacity containers during their transportation, the lock-stop is made in the form of a movable along its longitudinal axis vertically and spring-loaded pin installed in the guide housing, the guide housing can be fixed on the end beam of the platform frame; the guide housing can be made in the form of a bushing, covered from above by a guide ring, in the central hole of which the upper end of the guide pin is placed, the bushing is fixed to the frame with a bracket; the guide pin can be provided with a thrust collar interacting with the upper end of the compression spring placed in the guide housing between the thrust collar and the bottom of the guide housing, a central hole is made in the bottom of the guide housing, in which the lower end of the guide pin is placed; a stop shoulder can be made at the lower end of the guide pin and serves as a stop for the upper end of the compression spring; the vertical force developed by the stopper pin can be from 5000 to 30000 N.

The claimed utility model differs from the prototype in that the latch-stop is made in the form of a finger movable along its longitudinal axis and spring-loaded in the guide housing, the guide housing is fixed on the end beam of the platform frame; the guide housing is made in the form of a bushing, covered from above by a guide ring, in the central hole of which the upper end of the guide pin is placed, the bushing is fixed to the frame with a bracket; the guide pin is provided with a thrust collar interacting with the upper end of the compression spring placed in the guide housing between the thrust collar and the bottom of the guide housing, a central hole is made in the bottom of the guide housing, in which the lower end of the guide pin is placed; the vertical force developed by the latch-stop pin can be from 5000 to 30000 N. Such differences from the prototype give reason to assert that the proposed technical solution meets the utility model patentability criterion - "novelty".

The utility model is shown in the drawings, where:

- in Fig. 1 - railway platform for the transportation of large containers, main view;

- in Fig. 2 - large-capacity containers mounted on the platform frame, undercarriages are not conventionally shown, isometric view;

- in Fig. 3 - remote element "A" from Fig. 2, isometric view;

- in Fig. 4 - longitudinal section of the latch;

- in Fig. 5 - the same, a simplified design of the latch.

The railway platform 1 (Fig. 1) for the transportation of large-capacity containers 2 contains a frame 5 installed on the undercarriage 4 with end beams 5.1 (Fig. 2). The frame 5 is equipped with stoppers 6 to prevent the opening of the end doors 2.1 of large-capacity containers 2 during their transportation.

The latch-stop 6 is made in the form of a guide pin 6.2 movable along its longitudinal axis vertically and spring-loaded in its guide housing 6.1 (Fig. 3).

The guide body 6.1 can be fixed on the end beam 5.1 of the frame 5 of the railway platform 1, or in any other suitable place of the frame 5 of the railway platform 1.

The guide housing 6.1 can be made in the form of a bushing, covered from above by a guide ring 6.3 (Fig. 4), in the central hole of which the upper end 6.4 of the guide pin 6.2 is placed, the guide housing 6.1 is fixed to the frame 5 using the bracket 7.

The guide pin 6.2 is provided with a thrust shoulder 6.5, with which the guide pin 6.2 interacts with the upper end of the compression spring 8. The compression spring 8 is placed in the guide housing 6.1 between the thrust collar 6.5 and the bottom 6.6 of the guide housing 6.1. In the bottom 6.6 of the guide housing 6.1, a central hole is made, in which the lower end 6.7 of the guide pin 6.2 is located.

Thrust shoulder 6.5 (Fig. 5) can be made at the lower end of the guide pin 6.2 and serve as a stop for the upper end of the compression spring 8.

The vertical force developed by the guide pin 6.2 of the latch-stop 6 can be from 5000 to 30000 N.

The utility model is used as follows.

Large-capacity containers 2 are lowered onto the railway platform 1. In case of improper installation, namely, when placing a large-capacity container 2 on top directly on the latch-stop 6, it is vertically and spring-loaded mounted in its guide housing 6.1 guide pin 6.2, oriented with its upper end 6.4 in the central hole of the guide ring 6.3 and the lower end 6.7 in the central hole of the bottom 6.6, goes down, acting with its stop shoulder 6.5 on the upper end of the compression spring 8. After the large-capacity container 2 is correctly installed on the railway platform 1, the pin 6.2, under the influence of the compression spring 8, returns to its initial upper position, performing its function of the stoppers 6 to prevent the opening of the end doors 2.1 of the large-capacity containers 2 during their transportation on the railway platform 1.

For reliable operation of the stoppers 6, the vertical force developed by the guide pin 6.2 must be in the range from 5000 to 30000 N. If the force is less than 5000 N, the guide pin 6.2 may not work correctly, in particular, its upper end 6.4 does not come out of the central hole of the guide ring 6.3 when clogging with dust, debris, freezing of working gaps between the surfaces of the pin 6.2 and the surfaces of the central holes of the guide ring 6.3 and the bottom 6.6 of the guide housing 6.1. To obtain a force of more than 30,000 N, compression springs 8 with large dimensions will be required, which requires the manufacture of a guide housing 6.1 of increased weight and dimensions.

Thus, to ensure the operability of the locks-stops 6 to prevent opening of the end doors 2.1 of large-capacity containers 2, there is no need for manual operations to bring the locks-stops 6 into working or inoperative state, as in the known prototype, which serves to increase the operational reliability of the proposed device.
