Description

The utility model relates to railway vehicles and concerns the construction of railway platforms for the transport of containers.

Widespread transportation by road, rail and water transport of standard 40-foot containers of types 1AAA, 1AA, 1A, 1AX, having, according to GOST Ρ 53350-2009 (ISO 668: 1995), the overall length at the ends l _k 12192 mm. We have also mastered the transportation by road of 40-foot autonomous refrigerated containers (hereinafter referred to as refrigerated containers) with the same standard length at the ends l _k , but equipped at one end of the container with a hinged refrigeration unit (hereinafter referred to as HXA) protruding beyond the end of the container by the value l _gs , in the most convex middle part up to 750 mm.

Known is a fitting railway platform for transporting containers along 1520 mm track gauge at speeds up to 120 km / h model 13-198-02, having a length along the coupling axes of automatic couplings of 13920 mm, and along the end beams of the frame 12700 mm, providing installation on the platform frame of one 40 -ft or two 20-foot standard containers [1]. From the data of the longitudinal dimensions of the platform, it follows that for the transportation of two 40-foot containers, two platforms are required with a total length of at least 27840 mm along the coupling axes of automatic couplers (25400 mm between the extreme frontal parts (end beams) of the frames).

Known large-capacity 80-foot platform model 13-644, designed for the transportation of standard two 40-foot or four 20-foot containers on 1520 mm gauge railway tracks at speeds up to 120 km / h [2]. The length of the platform along the axes of the couplers is 25186 mm, the length of the frame is 24026 ± 6 mm. One such platform is shorter than two model 13-98-02 platforms.

The disadvantage of the above platforms is the impossibility of transporting two 40-foot autonomous refrigerated containers equipped with HXA, since the platform frame is made without taking into account the HXA protruding beyond the container end, and, therefore, without taking into account its overhang over the automatic coupler and the end part of the frame. This disadvantage makes it difficult for platforms to fit into the dimensions of the railway infrastructure when passing curved sections of the track, limiting the logistics of intermodal transportation of refrigerated containers.

Known railway long-base eighty-foot platform, taken as a prototype, containing a running gear, automatic couplers, a supporting frame in the form of a frame consisting of longitudinal, transverse, end and pivot beams, stationary and folding fittings stops, rotary fittings clamps, a container for installing navigation equipment. The length L _{1 of the} platform along the frontal plates is made equal to 25080 mm, while the length L _{2 of the} platform along the coupling axes of the automatic couplers is made equal to 26300 mm. A braking system with pneumatic and electric brakes is installed on the frame, made in the form of a block with a separate drive for each axle of the wheelset. The undercarriage is made in the form of two three-axle bogies [3].

The disadvantage of this platform is the excessive length of the platform frame along the front plates and, accordingly, the excessive length of the platform along the coupling axes of the automatic couplings, which leads to an increased metal consumption of the frame, complicates the conditions for the platform in the train to fit into the curved sections of the small-radius track on a track 1520 mm wide.

The technical result of the utility model is the optimization of the longitudinal dimension and metal consumption of the platform for the transportation of two 40-foot autonomous refrigerated containers equipped with NHA, the improvement of the conditions for the fit of the railway rolling stock into the curved track sections on the track with a width of 1520 mm.

The technical result is achieved by the fact that in the railway platform for the transportation of autonomous refrigerated containers with mounted refrigeration units containing a frame resting on two bogies, and automatic couplers, hinged from the ends of the frame, 25004 ... 25079 mm, ensuring the protrusion of the mounted refrigeration unit above the automatic coupler beyond the limits frames up to 400 mm in order to better fit into curved track sections on 1520 mm track width.

The essence of the utility model is illustrated by drawings:

- in Fig. 1 is a side view of the platform;

- in Fig. 2 is a top view of the platform.

The railway platform contains a frame 1 of length L _p , resting on two bogies 2. On the frame 1 from the side of its frontal parts (end beams), automatic couplers 3 are pivotally attached, protruding relative to them in the longitudinal direction by the value "a". On the loading surface of the frame 1, two 40-foot autonomous refrigerated containers 4 with a length l _k with HXA 5 are installed, protruding in the middle part from the end of the refrigerated container 4 by a value of l _gs ≤750 mm. The longitudinal size of the frame 1 along the frontal parts (end beams) of length L _p provides for the installation of two 40-foot autonomous refrigerated containers 4 equipped with HXA 5, with the HXA oriented towards the nearest automatic coupler 3. L _ac is the overall length of the platform along the coupling axes of couplers 3.

The platform works as follows.

The length L _{p of} frame 1 is 25004 ... 25079 mm, which ensures the overhang of HXA 5 over the automatic coupler 3 by an amount "b" up to 400 mm inclusively outside the frame 1, which is necessary to fit the platform into the track infrastructure gauge when passing curved track sections. The dimension b = 400 mm is normative in accordance with the requirements of the Agreement on International Freight Traffic by Rail (hereinafter - SMGS) Chapter 1, Section 4, Clause 4.2.

Overall length L _{p of the} frame 1 along the frontal parts (end beams) is determined by the sum of the lengths of two 40-foot self-contained containers 4 (2 × 12192 mm), taking into account the maximum protrusion of the HXA 5 (2 × 750 mm) minus the values "b" of the overhang of the HXA over automatic couplings 3 (2 × 400 mm):

L _p = 2 (l _k + l _gs -b), where:

- l _k is the length of a 40-foot container (from end to end);

- l _gs is the maximum dimension of the HXA protrusion from the end of the container;

- lgs≤750 mm (according to the conditions of their transportation by road);

- b - overhanging of HXA over automatic couplings - value normalized by SMGS, allowed within the limits of HXA protrusion beyond the frame of no more than 400 mm (connected with ensuring that the railway rolling stock fits into curved track sections on a track 1520 mm wide).

Taking into account the tolerances in the manufacturing process, the length L _{p of the} frame 1 of the platform for transportation of two 40-foot autonomous refrigerated containers 4 equipped with НХА 5 with НХА 5 orientation towards the nearest automatic coupler 3 along the frontal parts (end beams) will be 25004 ... 25079 mm.
