Description

 The present invention relates to aircraft, and in particular to devices that serve to load the cargo compartments of aircraft with side loading hatches, and can be used in the construction of cargo, passenger aircraft and helicopters.

 At present, the Taypor Onboard Forklift is known (see J. Flyt on 10/30/69), consisting of two inclined guides connected with the lower edge of the load carrier and with the support on the ground. A loading platform moves along inclined guides, which is in a horizontal position and is fixed on a triangular truss with rollers entering the grooves of the inclined guides. The rails are connected to the ground, and when the aircraft draws from the weight of the cargo, it should take into account the possible movement of the lower edge of the cargo hatch.

 One of the drawbacks of an on-board forklift is the lack of autonomy, because when loading goods with a forklift, an additional ground-based lifting device is required to reload goods (containers, etc.) from ground transport to the horizontal freight platform of the forklift. Due to the large dimensions, the “Onboard Forklift” has a large weight, which makes it difficult to load it inside the cargo compartment of the aircraft, where it occupies a sufficiently large usable volume of the cargo compartment.

 Also known is a "device for loading an aircraft" (see US patent N 4.586.684 class. 244-137, MKI B 64 D 9/00 published 05.06.86), consisting of a folding frame on the ropes located in the cargo aperture hatch. Inside the frame there is a cargo platform with four supports that fold down and an electromechanical mechanism located inside the cargo platform; 4 cables connected to the upper frame and the four corners of the cargo platform by means of an electromechanism provide lifting the cargo platform from the ground to the level of the upper frame or the level of the cargo floor. The device is folding and in the stowed position is in the cargo compartment of the aircraft.

 When operating the device, the selected design requires the presence of a ground loader to reload cargo from ground transport to the cargo platform, while the folding frame located at the level of the floor of the cargo compartment seriously complicates the loading of cargo onto the cargo platform. A similar situation will be with unloading cargo from the cargo compartment of the aircraft. The winch electric drive is located inside the loading platform and requires an onboard power supply. In addition, the lifting mechanism of the loading platform has a sophisticated cable system, including four cables for the loading platform, which must be simultaneously wound by an electric winch. The presence of a hinged frame on the cables, an electric winch drive, 4 supports, complex cable wiring makes the design of the device for loading complicated and heavy, which is an additional disadvantage of the known device.

 The objective of the invention is the creation of an optimal design that provides autonomous loading of packaged (container, pallet and others) and single loads at any unequipped airfields into the cargo compartment of the aircraft.

 The specified technical result during the implementation of the invention is achieved by the fact that in the on-board loading device for autonomous loading of containers and other goods through a side cargo hatch containing a cargo roller platform with a lifting cable system, according to the invention, the deflectable cargo roller platform is pivotally mounted on the lower edge of the cargo door, and its lifting torso system through the guide rollers of two rotary triangular racks is connected with a cargo winch, on the cable of which passes through cutting guide rollers, captures for cargo are attached, in addition, a tilt stop for insurance in the raised position is installed on the deflected load roller platform.

 Thus, two rotary triangular racks with the help of a cable system, grips, winch, on the cable of which grips for cargo are attached, provide the lifting of goods from the ground or ground transport. A tiltable load-bearing roller platform pivotally mounted on the lower edge of the cargo hatch rises from the vertical position of the cargo platform using the cable routing of the cargo platform, into which the previously lifted load is lifted, ensuring its installation on the rollers of the cargo platform, by which the cargo is manually moved inside the cargo compartment, having a roller flooring. The proposed on-board loading device for the autonomous loading of containers and cargo allows the loading and unloading of piece packaged goods at any non-equipped airfields. The device also provides loading and unloading of goods from any ground equipment and from the ground.

 Two rotary triangular racks provide load lifting, and the load-bearing rotary roller platform included in the loading system, due to the additional lifting of the load to a horizontal position, provides the ability to manually move goods along the roller track inside the cargo compartment.

 The design of the loading device consists of simple elements that allow for quick installation and dismantling of the device on existing serial aircraft.

 A rational power circuit and design with simple structural elements ensures the minimum weight of the structure.

 Information confirming the possibility of carrying out the invention to obtain the above technical result are as follows.

In FIG. 1 shows a loading device in a side view in the stowed position;
In FIG. 2 shows a loading device at the time of lifting;
In FIG. 3 shows a loading device at the location of the cargo (container) at the time of its position on the cargo roller platform;
In FIG. 4 shows a loading device in a front view in a stowed position;
In FIG. 5 shows a loading device in a plan view.

 The on-board loading device for autonomous loading of containers and other goods through the side cargo hatch contains (see Fig. 1-5) a deflectable cargo roller platform 1, mounted in the opening of the cargo hatch on a hinge 2, and a lifting cable system 3 passing through the rollers 9, located on the rotary triangular racks 6.

 In this case, one end of the cable wiring is attached to the deflected cargo roller platform 1, and the other is the cable 11 of the cargo winch 14 for lifting the load. The upper position of the cargo roller platform 1 is fixed by the stop 7. On the front edge of the cargo roller platform, a hinge stop 16 is installed, and on the edge of the cargo hatch - a turning threshold 8.

 Two rotary triangular racks 6 with struts 5, fixed through a hinge 17 and a stiffness 12 on the thrust bearing 4, serve as a support for the guide rollers 9 through which the cable 11 passes to lift the load, while at the end of the cable they are attached to the cargo grippers 13, and the other cable cable wiring 3 serves to lift the cargo platform. The upper position of the load is fixed by the stop 15.

 Thus, before loading from the opening of an open cargo loader, two rotary triangular racks 6 are withdrawn and fixed by braces and at the same time the load roller platform 1 is deflected downward. A., which is provided by stops 15 established for this purpose. The load roller platform 1 from the initial vertical position is lifted by the cable wiring 3 to a horizontal level, which corresponds to It corresponds to the level of the upper edge of the rollers on the cargo compartment floor.

 The coincidence of the level of the lower surface of the cargo located on the rollers of the cargo platform 1 and the level of the upper edge of the rollers on the floor of the cargo compartment, allows you to transport the cargo inside the cargo compartment on the rollers of the cargo platform 1 and the rollers of the cargo compartment L.

 The unloading order is ensured by the same operations in reverse order.

 In the stowed position, two triangular swivel racks 6 with braces are located in the same plane along the cargo compartment. The load roller platform 1 in the stowed position is in a raised vertical position and is fixed to the two turns of the racks.

 In the working position, two triangular swivel racks 6 after opening the hatch are deployed in the open opening of the hatch and are fixed by struts. Pre-load roller platform 1 lowers down to a vertical position overboard L.A.

 During the operation of the loading device, the cargo fixed in the grips to the ground or on the ground equipment rises to the horizontal position of the cargo bottom at the level of the cargo floor L. After this, a cable system 3 is brought under the load by a cable system 3, which provides its additional rise to the level of the upper edge of the rollers or balls of the cargo compartment. Roller decking provides the ability to move cargo into the opening of the hatch and further in the cargo compartment.

 The above information indicates the fulfillment of the aforementioned technical task when using the inventive airborne loading device, namely, loading and unloading piece and packaged goods at any non-equipped airfields, from any ground equipment and from the ground. Using the proposed solution will also allow for quick installation and dismantling of the device on existing serial aircraft, and a rational power circuit with simple structural elements provide the minimum weight of the structure.

 From the above it also follows that the claimed invention meets the criterion of "industrial applicability".
