- the device does not provide full safety when loading cars on its own on the upper tier;

- the device does not allow the commercial loading of the cargo cabin of the aircraft in full if it is on board the aircraft;

- the device provides for the mandatory presence of professional drivers when loading and unloading cars;

- the device provides for the mandatory presence of a crane beam on the plane in order to raise and lower the stairs.

The technical result of the claimed invention is the elimination of these disadvantages.

The technical result of the claimed invention “Device for loading, fixing and transporting cars in aircraft such as the heavy transport aircraft AN-124” is achieved by the fact that compared with the invention adopted as the prototype “Device for two-tier loading, fixing and transporting cars in aircraft of the type heavy transport aircraft AN-124 ”, containing a loading platform of the upper tier, made collapsible, including transverse beams with a longitudinal attached to them and elements, a device for fixing cars, in the claimed invention, the design of the loading platform of the upper tier is made in the form of separate sections formed by one transverse beam, with the exception of the lifting section formed by two transverse beams and longitudinal elements in an amount equal to at least two and not more than four made in the form of profiles having vertical edges at the edges to prevent the vehicle from converging when it moves along them and having a distance between these edges of at least a width of EU transported vehicles, with each section of the loading platform of the upper tier suspended on rods fixed at one end to the guide rails intended for the aircraft crane-beam located under the ceiling of the cargo compartment of the aircraft, and the other end to the transverse beams of the sections of the loading platform of the upper tier, one of the sections of the loading platform of the upper tier is made lifting by means of an airplane winch through the pulley system and with the possibility of transporting vehicles fixed to it when it rises to the level of the loading platform of the upper tier.

The design of the loading platform of the upper tier is made of separate sections, which allows it to be used both for the entire length of the cargo compartment of the aircraft, when assembling them, and separately for each section for transporting one or two cars, using two transverse beams.

In addition, an additional technical result is achieved in that the thrust of each section of the loading deck of the upper tier is made with the possibility of changing their length to regulate the height of the loading platform of the upper tier relative to the floor of the cargo compartment of the aircraft, which allows maximum use of the volume and commercial loading of the cargo compartment of the aircraft.

In addition, an additional technical result is achieved by the fact that the lifting section of the loading platform of the upper tier has wheels for its rolling on the floor of the cargo compartment of the aircraft from its bow to the tail and vice versa, which allows cars to move in one direction when loading and unloading, if There is a need for this.

In addition, an additional technical result is achieved by the fact that the device is configured to change the transverse distance between the longitudinal elements of the loading platform of the upper tier depending on the gauge of the transported vehicles.

A device for loading, fixing and transporting cars in aircraft such as the heavy transport aircraft AN-124 contains a loading platform of the upper tier, made collapsible, including transverse beams 1 (Figs. 1-4, 6, 8, 9) with longitudinal elements fixed to them made in the form of profiles 2 (Fig.1-9). Cross beams 1 (Figs. 1-4, 6, 8, 9) of the loading platform of the upper tier are suspended by rods 3 (Figs. 1, 4, 8, 9) to the guide rails 4 (Figs. 1, 4, 9) for crane-beams of the aircraft . Depending on the gauge of the transported cars on the loading platform of the upper tier, the longitudinal elements 2 (Figs. 1-9) have several mounting options relative to the transverse beam 1 (Figs. 1-4, 6, 8, 9).

If necessary, cars can be transported in one row at the loading platform of the upper tier, while it is necessary to lay and fasten only two rows of longitudinal elements 2 (Figs. 1-9) onto the transverse beams 1 (Figs. 1-4, 6, 8, 9) .

Rods 3 (figures 1, 4, 8, 9) consist of two halves, which are displaced and fixed relative to each other, which allows changing their length, thereby adjusting the height of the loading platform of the upper tier relative to floor 5 (figures 1, 4) and ceiling 6 (figures 1, 4) of the cargo compartment of the aircraft.

Using a tackle system consisting of rollers 7 (FIG. 1) and ropes 8 (FIG. 1), using an airplane winch (not shown in the drawing), raise or lower the loading platform (12), on which one or two cars can be standing on the longitudinal elements 2 (Fig.1-7) lying on two transverse beams 1 (Fig.1-4, 6).

Moreover, the loading platform of the upper tier is made in the form of separate sections 9 (Figs. 1-3, 8, 9), each of which is formed by one transverse beam 1 (Figs. 1-4, 6, 8, 9), with the exception of the lifting section (12) formed by two transverse beams 1 (Fig.6, 7) and longitudinal elements in an amount equal to at least two and not more than four, made in the form of longitudinal profiles 2 (Fig.1-9) having vertical edges at the edges 10 (Fig.5, 7) to prevent the vehicle from converging when it moves along them and having a distance between these ribs 10 (Fig.5, 7), not less wheel width of transported cars. Each section 9 (Figs. 1-3, 8, 9) of the loading platform of the upper tier is suspended on rods 3 (Figs. 1, 4, 8, 9), fixed at one end to the guide rails 4 (Figs. 1, 4, 9) , for the crane-beam of the aircraft located under the ceiling 6 (Fig. 1, 4) of the cargo compartment 11 (Figs. 1-4) of the aircraft, another for the transverse beam 1 (Figs. 1-4, 6, 8, 9). In the front part of the cargo compartment 11 (Figs. 1-4) of the aircraft, there is a separate lifting section 12 (Figs. 1-3, 6-7), consisting of two transverse beams 1 (Figs. 1-4, 6) and four longitudinal elements 2 (FIGS. 1-7), which, with the help of rollers 7 (FIG. 1), mounted on the guide rails 4 (FIGS. 1, 4), and cables 8 (FIG. 1) of the tackle system can be raised and lowered by an airplane winch ( not shown in the drawing). The lifting section 12 (Figs. 1-3, 6) is arranged to transport one or two cars mounted on it when it rises to the level of the loading platform of the upper tier. To do this, it is necessary to fix the transverse beams 1 (Fig.6-7) to the guide rails 4 (Fig.1-4) using rods 3 (Fig.1.4) to prevent its vertical displacement during the flight. The loading area of the upper tier in the assembled state is fixed by chains 13 (Figs. 1-4) from longitudinal, transverse and vertical displacements. Rod 3 (Figs. 1, 4, 8, 9) of each section 9 (Figs. 1-3, 8, 9) and section 12 (Figs. 6-7) of the loading platform of the upper tier are configured to change their length and adjust the height loading area of the upper tier relative to the floor 5 (Fig.1, 4) and cargo compartment 11 (Fig.1-4) of the aircraft.

The lifting section 12 (Figs. 1-3, 6) of the loading platform of the upper tier has wheels 14 (Figs. 4, 7) for rolling it along the floor 5 (Figs. 1, 4) of the cargo compartment 11 (Figs. 1-4) of the aircraft from its nose to the tail and vice versa.

The device is configured to change the transverse distance between the longitudinal elements 2 (Figs. 1-9) of the loading platform of the upper tier, depending on the gauge of the transported vehicles, which is achieved by several options for attaching the longitudinal elements 2 (Figs. 1-4, 8) to the transverse beams 1 (figures 1-4, 6, 8, 9). The design of the loading platform of the upper tier contains a device for fixing cars (not shown in the drawings) to the longitudinal power elements 2 (Figs. 1-4, 8, 9).

The operation of the device for loading, fixing and transporting cars in aircraft such as the heavy transport aircraft AN-124 is as follows.

Depending on the height of the vehicles transported on the loading platform of the upper tier, the length of the rods 3 is determined, which are attached at one end to the guide rails 4 with an interval equal to the length of the longitudinal element 2 (Figs. 1-9) along the length of the fuselage, transverse to the other end beams 1.

On the transverse beam 1, longitudinal elements 2 lie and fasten with the necessary transverse distance, depending on the gauge of the transported vehicles, forming a separate section of which the loading platform of the upper tier consists. The longitudinal elements, interconnected along each other, form 4 or two continuous paths for moving automobile wheels along them.

In the front of the cargo compartment 11, a lifting section 12 is assembled, consisting of two transverse beams 1 and four (or two) longitudinal elements 2, which, with the help of rollers 7 mounted on the guide rails 4, and cables 8 of the pulley system, can be raised and lowered by an airplane winch .

When the loading platform of the upper tier is assembled, it is fixed by chains 13 from longitudinal, transverse and vertical displacements. After the loading platform of the upper tier is fixed by chains 13, it is ready for operation.

Two cars in turn call in on the lifting section 12 and rise to the level of the loading area of the upper tier using an airplane winch. After that, the longitudinal beams of the lifting section are fixed with the longitudinal beams of the loading platform of the upper tier, after which the cars independently move along the longitudinal elements 2 to the appointed place and are attached by the device for fixing to the longitudinal elements 2.

After the loading area of the upper tier is completely filled, the last two cars call in the lifting section 12 and rise to the level of the loading area of the upper tier. The transverse beams 1 of the lifting section are connected to the guide rails 4 (Figs. 1, 4) using rods 3 similarly to section 9 (Figs. 1-3, 9), while the pulley system from the lifting section 12 is not disconnected.

The longitudinal elements of the lifting section 12 are fixed stationary to the longitudinal beams of the loading platform of the upper tier and the lifting section 12 is fixed by chains 13. Cars are attached by devices for fixing to the longitudinal elements 2.

To unload cars from the loading platform of the upper tier, it is necessary: to disconnect the longitudinal elements, rods 3 and chains 13 of the lifting section 12 and lower it with the help of the tackle system. Cars move out of the lifting section 12, after which it rolls, if necessary, into the tail of the aircraft fuselage. Using the same rollers 7 and cables 8 of the chain hoist system with an airplane winch, it rises to the level of the loading platform of the upper tier and is fixed by longitudinal beams to it. Two cars after mooring move to the lifting section 12, after which it is disconnected from the loading platform of the upper tier and lowers to the floor 5 of the aircraft, the cars move off and the process repeats.

The design of the loading platform of the upper tier, with a total length of longitudinal beams of about 43 m, allows you to load and install in two rows 20 cars of the Zhiguli or UAZ-469 brand or 18-20 jeeps of any modification. At the same time, there are 5 aircraft on the floor, i.e. on the lower tier, you can install in three rows 30 “Zhiguli” or UAZ-469 cars, taking into account ramps, or 27-30 jeeps of any modification. The device allows you to transport vehicles with a length of 10 m, a width of 2 m and a height of 2.2 m at the loading platform of the upper tier. The estimated weight of one car is 2.5 tons. Moreover, the cars do not require additional labor-intensive preparation for transportation.

As for loading the floor of the cargo compartment of the aircraft (lower tier), there are no restrictions, with the exception of the height, which depends on the height of the vehicles transported on the loading platform of the upper tier. The height of the lower tier can be adjusted within 2.2-3 m inclusive. This allows you to transport on the floor of the cargo cabin of the aircraft (on the lower tier) KAMAZ class cars, up to 3 m high, or other cargoes, for example, sea containers.

The loading platform of the upper tier can be used for transporting people, after laying and securing the flooring (floor) on the longitudinal elements 2 (Figs. 1-7), while heavy military equipment can be transported on the lower tier.

The maximum time for loading and mooring cars is no more than 2 hours. When transporting goods on the cargo area of the upper tier, and on the floor of the cargo compartment of the aircraft (lower tier) of cargo, the total loading time will depend on the nature of the goods for which there are established standards.
