Description

The field of technology.

The claimed invention relates to the field of railway transport and is intended for loading an automobile semitrailer onto a flat car in which it is transported.

Prior art.

It is known that railway flatcars with a low level in the intercarriage space (the so-called "pocket") are used to transport semi-trailers in combined transport conditions (publication on the Internet https://tatravagonka.sk/wagons_tax/intermodal/? lang = ru, [1]).

From the prior art, the method of loading an automobile semitrailer on a flat car, selected as a prototype, is known (patent RU 2675745 for invention, IPC B61D47 / 00, B66F7 / 02, published on 24.12.2018, [2]), in which the semitrailer is placed in removable basket, installed on the support legs resting on the additional transverse beam of the basket. In this case, the wheels of the semi-trailer are located between the transverse beams of the basket. Then, with the help of lifting means, the basket with a semitrailer is lifted above the ground and installed on a flat car. In this case, the basket is placed on the surface of the earth before placing the semitrailer in it. In this case, the interaction of the platform car and the basket occurs through the support platforms and energy-absorbing buffers placed on the latter. At the same time, when loading and installing on a platform car, the baskets with a semitrailer are placed and securely fixed against displacement in the pockets formed by the transverse beams of the basket.

However, the transfer of loads from the basket to the car through the energy-absorbing buffers and through the support platforms leads to the need to control (for example, tightening bolted connections) replacement of these elements during operation due to wear resulting from the action of friction forces and crushing loads.

Thus, the disadvantage of this method of loading is the need to control the technical condition of the energy-absorbing buffers and support pads of the basket during operation.

The technical problem, the solution of which is provided in the implementation of the technical solution, is the increased time spent on the maintenance of the basket during operation, which leads to an increase in the time of loading the semitrailer onto the wagon.

Disclosure of the proposed technical solution

The technical result is to reduce the time of loading a semitrailer onto a flat car.

Another technical result is an increase in the wear resistance of the contact surfaces of the basket and the car.

The specified technical results are achieved by the method of loading a car semitrailer onto a flat car, in which the semitrailer is placed in a removable basket using a tractor. In this case, the platform car and the basket interact in the longitudinal direction by means of the contact of the basket cross beams and the brackets of the side beams of the car frame, and in the vertical direction by supporting the upper straps of the side beams of the basket on the upper shelves of the side beams of the car frame.

In a particular case, the contact of the basket cross beams and the side beam brackets of the car frame is carried out through the grooves in the basket cross beams.

Unlike the prototype, in the proposed technical solution, the transfer of loads is carried out directly through the metal supporting structures of the basket.

The transfer of loads in the longitudinal direction through the basket beams to the brackets of the side beams of the car frame allows an increase in the number of contact points, due to the decrease in the load on one contact point, as a result of which there is no need to use energy-absorbing buffers.

The support of the upper straps of the basket on the upper flanges of the side beams of the car frame along the entire length of the upper straps of the side beams of the basket allows to distribute the vertical load along the entire length of the beam, due to which, unlike the prototype, there are no local contact zones, as a result of which the wear of the contacting surfaces of the basket and the car is reduced and there is no need to use support pads.

Thus, in comparison with the prototype, due to the increase in the total area of contact between the car and the basket, the wear resistance of the contact surfaces of the basket and the car is ensured. At the same time, the places of contact between the car and the basket do not require maintenance in operation, as a result of which the declared technical result is achieved - a reduction in the time of loading the semitrailer onto the platform car.

Thus, the claimed invention differs from the prototype in that the interaction of the platform car and the basket in the longitudinal direction occurs through the contact of the cross beams of the basket and the carriage brackets welded to the side beams of the car frame, and in the vertical direction by supporting the upper straps of the side beams of the basket on the upper shelves of the side beams of the car frame.

Brief description of the drawings.

The proposed invention is illustrated by graphic material:

- in Fig. 1 shows a general view of a semitrailer in a basket installed on a flat car;

- in Fig. 2 shows a general view of a semitrailer in a raised basket;

- in Fig. 3 shows a general view of the basket without a semitrailer.

Implementation of the technical solution.

The method of loading an automobile semitrailer 1 onto a platform car 2 (Figs. 1, 2) includes loading a semitrailer 1 into a basket 5 and installing a basket 5 on a car 2 similar to the prototype, except for the interaction of the car 2 and the basket 5 in the longitudinal and vertical directions.

The basket 5 (Fig. 3) contains the upper straps 6 of the side beams, the side beams 7 and the cross beams 8.

The frame 3 of the car 1 contains the brackets 9 of the side beams, located in the inter-bogie space of the frame 3 of the car 2.

The interaction of the platform car 2 and the basket 5 in the longitudinal direction occurs through the contact of the beams 8 of the basket 5 and the brackets 9 of the side beams of the car frame 2, and in the vertical direction by supporting the upper straps 6 of the side beams 7 of the basket 5 on the upper shelves 10 of the side beams of the car frame 2 ...

Unlike the prototype, the load in the vertical direction from the basket 5 to the car 2 is transmitted through the upper straps 6 of the basket 5 to the side beams of the frame 3 of the car 2. The load in the longitudinal direction from the basket 5 to the car 2 is transmitted through the beams 8 of the basket 5 to the side brackets 9 frame beams 3 of the car 1.

In a particular case, the contact of the beams 8 of the basket 5 and the brackets 9 of the car is carried out through the grooves in the cross beams 8 of the basket 5

The implementation of the proposed method of loading a car semitrailer onto a flat car is not limited to the above example.

Industrial applicability.

The claimed invention is implemented using commercially available devices and materials and can be applied at any railway company.
