Description

The invention relates to the field of production of vehicles for the transportation of wheeled equipment by railway.

A well-known coupling of platforms for the transportation of wheeled equipment (1), where the platforms are made with a supporting frame, without side boards. Fixing of wheeled equipment is performed by installing brake shoes under the wheels in the form of isosceles triangles, which are attached to the floor of the platform. Brake shoes are installed at an angle to the longitudinal axis of the platform, fixing the equipment simultaneously in the longitudinal and transverse directions.

A well-known platform for the transportation of road trains |2|), where the brake shoes are made in the form of an isosceles triangle with cylindrical stops on the sole, shifted from the middle of the triangle by a quarter of a step of a row of holes in the platform floor. The stops at the end are made with ring protrusions, which prevent the possibility of shocks leaving the holes during vibrations. Brake shoes are installed parallel to the transverse axis of the platforms. It is assumed that they will ensure that the wheels of the road train are kept from longitudinal and transverse movements under the influence of dynamic loads in the train.

A well-known platform for the transportation of IZI semi-trailers. The platform is made with centering sides that limit the lateral movements of semi-trailers, and is equipped with a two-track carriageway with a floor that descends in the middle part of the platform. The flooring is made with windows for brake shoe stops. The brake shoes are made in the form of an isosceles triangle and in the transport position are attached to the board of the platform.

A well-known platform for containers and wheeled machinery I4| with end sides, a lowered loading platform between the running parts in the form of two rectangular chutes, with container supports that are placed on rotating shields and are removed from the loading platform by turning the shields to a vertical position above the side of the platform. The disadvantage of the platform is the need for additional securing of the wheeled machinery from lateral displacements and the difficulty of performing these works when the rotary shields are in a vertical position.

A well-known prototype platform for transporting wheeled machinery and containers (5| with running parts, a supporting frame, a two-track carriageway with a floor and brake shoes for fixing and fastening wheeled machinery in the longitudinal direction, made in the form of an isosceles triangle. The floor is made with two rows of minimum pitch windows for the installation of brake shoe stops and is limited by the width of the carriageway by wheel buffers. The brake shoes are made in the form of an isosceles triangle with stops fixed in the middle of the sole. The platform ensures the transportation of wheeled equipment with a variety of undercarriage designs.

The prototype has the following disadvantages: the need to use high-strength materials for the manufacture of flooring with a small window step (minimum thickness of the bridges between the windows), which ensures a minimum technological gap between the brake shoes and wheels; the high complexity of manufacturing a floor equipped with windows with a small step between them.

The task of the invention is to ensure the fastening of wheeled equipment with minimal technological gaps while excluding the use of high-strength materials for the manufacture of flooring and reducing the labor intensity of its manufacture.

The task is solved by the fact that the platform, which includes elements common to the prototype - running parts, a supporting frame with a carriageway, made with the limitation of lateral displacement by wheel buffers and a floor equipped with windows, and brake shoes with stops on the soles has new technical solutions. The brake shoes are made with removable stops and two rows of sockets in the sole under the stops with a step determined by the strength of the elements of the brake shoe, and the flooring is made with two rows of windows with a larger step, a multiple of the step of the sockets in the sole of the brake shoe.

Making brake shoes with removable stops and rows of nests under the stops in the sole with a step that is minimal in terms of strength, and flooring with rows of windows under the stops with a larger step reduces the cost of manufacturing the floor due to the use of less durable material, reducing the number of windows.

The execution of the brake shoe in the form of an inequilateral trapezoid (its extreme case is an inequilateral triangle) provides the possibility of installing a brake shoe with a minimal technological gap between the wheel and the brake shoe, a smaller gap of the sockets in the sole. The execution of the brake shoe in the front of the trapezoid reduces the probability of the wheel rolling through the brake shoe and damage to the tires of pneumatic wheels from excessively large bends at the top of the brake shoe during dynamic loads of the platform with cargo.

This invention ensures the reliability of fastening while reducing the labor intensity and cost of manufacturing the platform in comparison with analogues and the prototype.

The essence of the invention is explained by the drawings: Fig. 1 shows a platform with a road train, a side view; Fig. 2 shows the carriageway with brake shoes installed on the floor (Fig. 1, section

A-A); Fig. 3 shows the pavement of the carriageway (Fig. 1, view B); Fig. 4 shows the brake shoe, side view (Fig. 2, section B-B); Fig. 5 shows the brake shoe, top view (Fig. 4, section G-G); Fig. 6 shows the removable stop of the brake shoe in the socket (Fig. 5, section D-D).

The railway platform for the transportation of wheeled equipment and containers is made as follows. On the running parts 1 (fig. 1) a frame 2 with end sides 3, a two-track roadway with a floor 4 is installed. The floor 4 on the outside of the roadway is equipped with a wheel buffer 5. To fix the wheeled equipment 6, the platform is equipped with brake shoes 7, which limit the movement of the wheels 8.

Brake shoes 7 are equipped with stops 9 (Fig. 2), and the floor 4 (Fig. 3) is equipped with cylindrical windows 10.

Brake shoes 7 (Fig. 4) are made in the form of an equilateral trapezoid. The sole 11 (Fig. 5) of the shoe 7 is made with sockets 12, the step of which is less than the step of the windows 10 in the deck 4. The stop 9 (Fig. b) is made with a centering surface 13, holding it in the socket 12 of the sole 11 of the shoe 7, and an annular protrusion 14, preventing the exit of the stop from the window 10 in the floor 4 of the carriageway.

The platform is used as follows. The platform (Fig. 1) relates to the end loading platform, the end board 3 is lowered, forming a transition bridge to the platform. The wheeled machinery 6 moves along the end board Z and the deck 4 onto the platform. Wheel buffers 5 center the wheel machinery 6, which moves, compensating for the inaccuracy of the driver's control. After stopping in the area of the platform required by the loading conditions, brake shoes 7 are installed in front of the wheels 8. Stops 9 (Fig. 5) through sockets 12, converging at the smallest gap between the wheel 8 (Fig. 4) and the brake shoe 7 with windows 10 (Fig. .5), the brake shoes 7 are fixed on the floor 4. In order to select the smallest gap, the brake shoe 7 can be turned to the wheel 8 with a smaller or larger angle of inclination of the trapezoid (see Fig. 4). Next, the wheeled vehicle 6 (Fig. 1) runs over the installed brake shoes 7, selecting the gaps between the wheels 8 and the brake shoes 7, and brakes. In this position, the brake shoes 7 are installed behind the wheels 8. The brakes on the wheeled machinery b are released, the wheels 8 roll away from the brake shoes 7, distributing the gaps between the wheels 8 and the brake shoes 7 more evenly. After that, the wheeled machinery b is set on the parking brake and the speed is engaged . The end board 3 rises on the platform. The platform is equipped for railway movement.

Unloading of wheeled machinery is carried out as follows. The platform is installed to the end loading platform, the end board C is folded into a horizontal position (Fig. 1). The wheel machinery 6 is fed forward or backward to the stop of the wheels 8 in the brake shoes 7, releasing the brake shoes 7 from the other side of the wheels 8 until it is possible to remove the stops 9 (fig.b) from the windows 10 in the floor 4. After removing the stops 9, the brake shoes 7 are removed. and the wheel mechanism 6 (Fig.1) is slightly fed in the opposite initial movement of the tension, releasing the last brake shoes 7, which are removed. Wheeled machinery 6 is prepared for movement. Depending on the orientation relative to the loading platform, the vehicle leaves the platform in front or reverse, moving with a lateral shift within the channel formed by the wheel bumpers 5.
