Description

Field of technology

The utility model relates to the field of railway transport and is intended for the placement, fastening, transportation of railway wheel pairs, as well as the storage and sorting of railway wheel pairs in storage areas.

State of the art

A cradle for transporting and storing railway wheel sets is known from the prior art (RU 2814737 C1, publication date 04.03.2024). The cradle is comprised of a pair of symmetrical support elements spaced apart from each other, as well as structural elements that geometrically repeat the shape of the rim of a railway wheel, the support elements are manufactured in the form of integral molded structures made of a porous elastic non-metallic material having a high coefficient of friction, the cradle is designed with the possibility of installing it directly on the platform of a vehicle for transporting wheel sets, the structural elements, geometrically repeating the shape of the rim of a railway wheel, are formed in a recess located on the upper surface of the support element, having a radial stepped geometric profile of a complex shape, wherein a protrusion is formed in the profile of the recess, geometrically repeating the shape of a brake shoe, or two symmetrical protrusions, geometrically repeating the shape of a brake shoe. The disadvantage of this design is the asymmetrical placement under the wheelset rims and the lack of fixation against movement during dynamic transportation, which leads to collision of the wheelset rims and, as a consequence, their damage.

A detachable, reusable system for transporting railway wheelsets on universal flatcars (RU 180476 U1, published June 14, 2018) is known. It consists of detachable beams, mounting stops, and containers. Each container consists of a base, a support, three posts, and crossbars with shock absorbers. A disadvantage of this solution is that it is transported exclusively by rail, and the structure is prone to tipping when loaded with wheelsets.

The closest analogue is a removable multi-turn device for transporting wheel sets on universal platform cars (patent RU 187019, published 02/13/2019), made in the form of a container consisting of a base and a support; the base of the container contains lugs for additional fastening of the base to the platform car using stretchers.

Transportation of wheel sets with the specified device (under patent RU 187019) is carried out in accordance with the "Local technical conditions for the placement and fastening of 36 wheel sets with axle boxes and without axle boxes on flat cars of models 13-4012, 13-6887, 13-6887-01 with removable multi-turn fastening means according to the VACT.057.00.00.000 project", approved by the order of JSC Russian Railways No. 1316/r dated 22.06.2018, hereinafter referred to as the MTC (published on the Internet http://www.consultant.ru/cons/cgi/online.cgi?req=doc&base=EXP&n-399180#09136475083755311).

The MTU text states that when returning the device empty, the supports are installed inside the bases and additionally secured to the bases using wire ties. Each support is secured to the corresponding base with four ties using crossbars. The supports are restrained from longitudinal movement by vertical base pins. This method of securing the supports secures them against vertical, longitudinal, and lateral movement. However, this method of securing the supports to the bases requires time for tying, and the wire ties are a one-time securing component, which increases the cost of transporting the device. A disadvantage of this solution is the lack of mechanisms for securing the supports to the bases during transport of a removable multi-turn device empty (without wheelsets) to prevent vertical wheel set slippage, which is unacceptable. Also, dispatching wheel sets is only possible when the flatcar is fully loaded, which delays the repair time of other wheels while they wait for stockpiling.

The main problem with all the above-mentioned analogues is the impossibility of installing a bed on a vehicle for transporting wheel sets, the lack of mobility during loading and unloading, and the lack of clear positioning of wheel sets.

Disclosure of the essence of the utility model

The technical problem solved by the utility model is to overcome the technical shortcomings inherent in similar models, which leads to the need to create a bed for transporting wheel sets, ensuring safe and mobile transportation.

The technical result of the utility model consists in increasing operational reliability by ensuring precise positioning of wheel pairs taking into account the dimensions of the wheels.

The technical result is achieved due to the design of the bed for transporting wheel pairs, which is a welded structure in the form of a lattice, containing an outer contour and at least two longitudinal beams, characterized in that the outer contour contains lugs located at the corners, and on its opposite sides there are stops with a height of 100 mm and a distance between them of 150 mm, and on the longitudinal beams, there are also stops on the projections, ensuring the arrangement of wheel pairs in a second tier and a turn of 90° relative to the lower tier.

The bed may contain at least one pair of stops on each side.

The stops can be made in a triangular shape.

The eyes located at the corners of the outer contour provide slinging during loading and unloading by crane.

The stops, located in pairs on opposite sides of the outer contour, ensure that the wheelset is fixed from rolling away, as they are positioned taking into account the dimensions of the wheel and the length of the wheelset.

The stops, located in pairs on the beams, allow for the transportation of a larger number of wheel pairs.

The essence of the utility model is explained by drawings.

Fig. 1 - top view of the lodgement;

Fig. 2 - side view of the lodgement;

Fig. 3 - example of using the tray.

The following positions are indicated on the drawings:

1 - outer contour;

2 - beams;

3 - eyes;

4 - stops;

5 - protrusions.

The wheel set transport bed is universal and can be used both on a platform car and for transportation by road.

The bed is a welded structure consisting of an outer contour 1 and longitudinal beams 2. Eyes are located at the corners of the outer contour 1 to facilitate loading and unloading the bed using a crane. Stops 3 are located in pairs on opposite sides of the outer contour 1, symmetrically to each other, to prevent the wheelset from jumping out or falling out. Protrusions 5 with stops 3 are located on each beam 2, symmetrically and corresponding to the length of the wheelset, to accommodate an additional wheelset.

The utility model is implemented as follows.

The wheel pairs are placed on the bed one by one, first between the stops 4 located on the outer contour 1, and then between the stops 4 located on the projections 5. Then the bed is slung through the eyes 3 and moved by crane to a flatcar or motor vehicle.
