Description

The invention relates to ground handling equipment for aircraft, in particular to means for transporting, lifting and suspending cargo onto an aircraft, including on the deck of the ship.

A device is known comprising a trolley with a frame, a load-lifting device detachably mounted on the frame, equipped with replaceable cargo lodges (patent 2076831 Cl. B64F 1/32).

The disadvantage of this device is the inconvenience in operation, since with a slight roll on the deck of the ship this device does not provide suspension of the load if it is deflected in the transverse direction, the device has a complex structure, since it includes a hydraulic system.

The closest technical solution adopted as the closest analogue (prototype) is a device (patent No. 2046073, B64F 1/32 dated 04/29/1991), containing a trolley with a frame, a cargo platform detachably mounted on the frame and cable assemblies connected to winches.

The disadvantage of this device is the inconvenience in operation, since the specified device makes it difficult to suspend cargo with various centers of gravity and bearing points, as well as with slight rolling on the deck of the ship, this device does not provide suspension of cargo in case of deviation in the transverse direction, and does not provide suspension one operator.

The objective of the invention is to expand the operational capabilities of the device, ensuring the lateral stability of the lifted load and the implementation of the lifting and suspension by one operator.

The problem is solved due to the fact that in the device for transporting, lifting and suspending cargo onto an aircraft containing a trolley with a frame, a detachably mounted lifting device and a cable system connected to the winch, the lifting device is made in the form of a frame with openings provided with a fixed and a movable stand and a cable suspension system, and the movable stand and cable system are provided with fixing units for attachment to the frame, and the cable system at one end is provided with an alignment a balancer connected through an adapter to the winch cable, and at the other end it is equipped with deflecting rollers, the cable of which through the tip is connected to a suspension unit fixed to the aircraft carrier. In this case, the leveling balancer introduced into the cable system provides lateral stability of the lifted load.

The technical result of the invention is the expansion of the operational capabilities of the device due to the fact that when lifting and suspending loads having different alignment and different bearing places, it is possible to provide lateral stability of the lifted load if it is deflected in the transverse direction, while lifting and suspension can be performed by one the operator due to the presence of a lever, which can easily adjust the position of the load in the longitudinal direction.

In the case of deviation of the load in the transverse direction, the leveling balancer turns around, as a result of which a moment appears that evens the load. Suspension assemblies attached to the bulkhead of the aircraft are made in the form of a bracket with mounted bushings equipped with pins that have fungi at one end and at the other end of the winch, the pin interacting with the studs.

A console with an eye pivotally mounted on it is also mounted in the bracket.

As a result of the use of the invention, the design was simplified, the time of suspension of the load on the aircraft was reduced, and the operational capabilities of the device were expanded, because it is possible to lift and suspend loads having different alignment, different bearing places, it is possible to provide lateral stability of the load to be lifted in case of deviation in the transverse direction, i.e. the possibility of this work when rolling the ship. This device allows lifting and suspension to be made by one operator, i.e. there is a lever with which you can easily adjust the position of the load when lifting in the longitudinal direction.

A device for transportation, lifting and suspension of goods consists of a lifting device, suspension units and a transport trolley.

The lifting device (FIGS. 5 and 6) consists of a frame, a cable system and a winch with a bar and is intended for mounting it on a trolley, installing lodges on it for attaching different types of goods to them.

The lifting device consists of a frame 1, on which a fixed stand 2, a movable stand 3 and a cable system are fixed 4. The frame 1 also has openings 5 for fastening a movable stand 3 and a cable system 4 for hanging different types of loads with different attachment belts and with different centers gravity.

The frame 1 is also equipped with nodes 6 mounting to the trolley. The movable stand 3 is equipped with pins 7 and mounting nodes 9 (Fig.7 and 8) for attachment to the frame 1 and studs 8 for attaching lodges 30.

The cable system 4 is also equipped with pins 7 and mounting nodes 9 (Fig. 8) for attachment to the frame 1 and has cables 10 and deflecting rollers 11, and the cable 10 at one end has a tip 12 for connection to the suspension nodes 36 (Fig. 9) interacting with the aircraft carrier 31, and also has a leveling balancer 13, an adapter 14 (Fig.6) for attaching the cable 10 to the cable 15 of the winch 16 (Fig.2).

The frame 1 is also equipped with a pin 17 for connecting the rod 18 with the winch 16 using the bolt 33 (figure 2 and 5).

Suspension assembly 36 (Fig. 9) has right and left assemblies intended for fastening them to the aircraft carrier 31 and connecting them to the tips 12 of the cables 10 of the lifting device.

The suspension unit 36 consists of a bracket 19, in which two bushings 20 are mounted, equipped with pins 21, which have fungi 22 at one end and 23 at the other end, and the pin 21 has flats 24 for interacting with the studs 25.

A bracket 26 and an eye 28 are also mounted in the bracket 19, pivotally mounted using a bolt 27.

The device operates as follows:

- install the suspension units 36 right and left (Fig. 9) on the aircraft carrier 31 (FIGS. 1 and 2), to do this, insert the fungi 22 into the grooves of the carrier, having previously removed the studs 25 from the pins 21, then rotate the fungi 22 90 wrenches 23 and fix with studs 25;

- fasten to the trolley 32 (Fig.1) a lifting device using nodes 6 with studs 34;

- fix on the fixed 2 and movable 3 stand the necessary tool tray 30, depending on the load to be lifted, using the studs 8 (Figs. 1 and 7);

- depending on the load to be lifted, install the cable system 4 and the movable stand 3 in the required holes 5 and fix the necessary load on the tool holders 30;

- drive a lifting device with a fixed load to the carrier 31 of the aircraft on the trolley 32;

- connect to the pin 17 (figure 2 and 5) of the lifting device of the rod 18 with a winch 16 using a bolt 33;

- connect the cable 10 of the cable system (Fig.6) with the cable 15 of the winch 16 using the adapter 14;

- connect the tip 12 of the cable system to the eyes 28 (figure 1 and 9) using a bolt of the cable system and lock with a pin 29;

- tension the cables 10 and 15 using a winch 16;

- disconnect the lifting device with the load from the truck 32 (figure 1) by removing the studs 34;

- working with winch 16, we raise the load to the required height and, working with lever 35, one operator combines the load securing units with the reciprocal nodes of the airplane carrier;

- fix the cargo on the aircraft carrier;
