Description

 The invention relates to the field of aviation, namely to the equipment of aircraft designed for dropping cargo, and allows you to place loads of large masses and large sizes.

 Currently known loading and unloading system of a transport aircraft (see US patent N 3371891, CL 244-137, publ. 5.03.68). The design includes two support beams with reinforced rollers on which the movable frame can move. Inside it, also on rollers, another smaller movable frame is installed, on which there are a number of transverse beams. Hooks are hinged on the beams, to which weights are suspended by the rings. Unloading can be done remotely due to the presence of electric drives moving the movable frame, which facilitates the work of the crew to dump cargo during the flight.

 The closest design for the same purpose to the claimed invention in terms of features is a device for placing and landing cargo from an aircraft, known from the description of the patent of the Russian Federation N 2093424, MKI B 64 D 1/08, 9/00, publ. 10.20.97 g.

 This device contains roller tracks mounted on the floor of the cargo compartment, between which a monorail is placed.

 The device also contains pallets installed along the longitudinal axis of the aircraft, detachable devices for securing pallets on the aircraft, and detachable devices for securing cargo on pallets and ensuring the movement of goods under gravity to the landing position, while the device for securing cargo contains flexible traction, the ends of which are fixed on the sides of the cargo compartment in the ramp area, and the middle part - with the upper part of the cargo compartment in the ramp area.

 The reasons that impede the achievement of the technical result indicated below when using the known device adopted as a prototype include the fact that it is not efficient and convenient enough to accommodate large loads and large sizes.

 The basis of the present invention is the creation of a system for the placement and discharge of goods, which would provide the ability to accommodate loads of large masses and large sizes while providing increased efficiency and safety.

 The specified technical result in the implementation of the invention is achieved by the fact that the system for placing and dumping cargo from the aircraft, containing roller tracks mounted on the floor of the cargo compartment, between which a monorail is placed, according to the invention is equipped with a truss consisting of braces of the upper part on which the loads are placed , and the lower part with additional rollers installed on it, connected with ropes with winches pulling the farm along the roller tracks to the ramp on which there are two e lateral guides in contact with additional rollers; in addition, locks on the bottom of the truss are fixed, guiding the truss along the monorail and fixing it with clamps.

 Thus, the differences of the proposed system for the placement and discharge of cargo from an aircraft allows you to place loads of large masses and large sizes while providing increased efficiency and safety.

 Information confirming the possibility of carrying out the invention to obtain the above technical result are as follows: in FIG. 1 shows a side view of the proposed system, in FIG. 2 is a plan view of FIG. 3 - system in flight (in stowed position), in FIG. 4 - system in evacuation position, FIG. 5 is a section AA of FIG. 3.

 The system for placing and dumping cargo from the aircraft (see Fig. 1-5) contains roller tracks 5 mounted on the floor 1 of the cargo compartment, between which the monorail 4 is placed along the cabin axis. The system is equipped with a truss 3 consisting of a lower part 14 and an upper 9, connected by braces 6. On the upper part of the truss on the fixed ramp there are laden loads 7. On the floor at the beginning of the cargo compartment there are two winches 2 for moving the system inside the cargo compartment of the aircraft. Winches are connected by cables 8 to the lower part of the farm. On the bottom of the farm installed additional rollers 6 on the beam 13, which are in contact with two guides 10, which are placed on a ramp in the rear of the cargo compartment. On the floor of the cargo compartment there are two pairs of removable stops 11, limiting the course of the farm forward and backward. The lower part of the truss has locks 12 guiding the truss (to limit the movement of the truss sideways and forward - backward), the lock 15 of this lock is spring-loaded relative to the lower part of the truss, which makes it possible to fix the system in the lower position. During the delivery of the cargo to the discharge point, the system is located inside the cargo compartment, all the doors, ramp, pressure lock are closed. Before the discharge, the center, side and pressure shutters open, the ramp lowers to a horizontal position.

 The farm is pulled by a winch 2 until it stops 11 along the roller tracks 5 on the ramp so that the load hangs above the void behind the ramp.

 Locks 12, guiding the truss, fix it in the desired positions using the latch 15 and the holes in the monorail. "Extra" holes are closed (blocked) with stainless steel plates.

 At the end of the course of the farm (about 3 meters to the stop), two pairs of additional rollers 16 on each side of the farm come into contact with side guides 10 that prevent the farm from tipping over in both directions during the extension of the farm.

 The above information indicates the fulfillment of the aforementioned technical task when using the inventive system for the placement and discharge of cargo from an aircraft, namely the possibility of placing large masses and large cargoes while ensuring increased efficiency and safety.

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