Description

The invention relates to shipbuilding, and in particular to a method for storage and supply of aircraft fuel tanks placed on ships.

A known system for storing aircraft fuel tanks on the ceiling in hangars, used on aircraft carriers and universal landing ships of the US Navy and some other NATO countries. A feature of the applied method of supply and storage is that the fuel tank of the aircraft is placed on a trolley and sent from the flight deck of the ship to the hangar. Then, with the help of a lifting device, the fuel tank is moved to the feeder, which has the appropriate racks with lodges and a working platform for operators. The feeder is delivered to the storage location of the outboard fuel tanks, after which the fuel tank is lifted together with the operators who fix it to the structural elements of the storage facilities located on the ceiling. Storage facilities are metal pins welded to the ceiling and are equipped with attachment points for chain ties. Fuel tanks are fed between the indicated pins, and on the underside they are held only by chain ties, which have tape gaskets in the place of contact with the tanks. However, the disadvantage of this storage method is the lack of fastening of the upper part of the fuel tanks, which can cause their displacement with strong rolling or large angles of the roll and trim of the ship, which imposes certain operational limitations on this type of storage.

Also, a known method of storing aircraft fuel tanks directly on the feeder trolleys in the hangar of the ship, or in the premises allocated for this. However, this method of storage is possible only with sufficiently large areas of the ship's premises to allow the maneuvering of carts and their placement in specified storage locations.

Another known way of storing aircraft fuel tanks on ships is to store them together with the aircraft on the upper (flight) deck or in the hangar. However, this method of storing aviation fuel tanks can only be considered as additional (backup) to the above, due to the fact that in peacetime and, especially, in a combat situation, fuel tanks can be dumped, and the aircraft itself can land on a ship without them.

There is also a conveyor system for hanging fuel tanks developed for airplanes of the US Air Force F-15 type, the principle of which is that the fuel tank is fed on a trolley to the feeder, and then with the help of lifting devices it is installed in a vertical position and then made its movement to a given place in the conveyor. However, this storage method is applicable only for land conditions where there are no strict height requirements.

There is also a known method of storing aviation munitions on racks, which can also be used to store aviation fuel tanks (RF patents No. 2509043 "Storage rack for aviation munitions" and No. 2568157 "Universal small-sized storage rack for storing aircraft ammunition"). These storage facilities are a multi-tiered structure consisting of: racks, fixed beams and folding beams, lodgements mounted on them with means of restraint against displacement of aircraft ammunition in the conditions of rolling of the ship. The design feature of the racks is their versatility (placing products of different shapes on one rack due to replaceable lodgements), which allows you to select the optimal performance of the racks depending on the size of the ship’s space. However, this storage method with known racks has a number of disadvantages, namely: the room must be equipped with a lifting device with a large range of means of mechanization; it is necessary to have working aisles between storage facilities in the room, to provide areas for loading and unloading operations, since the racks recline at the racks. All this does not allow for the rational placement of aircraft hanging fuel tanks in ship buildings with a limited height.

The aim of the present invention is a method of deck storage and supply of aircraft fuel tanks in rooms with a limited height and insufficient area, which will ensure maximum loading of aircraft fuel tanks. This method of horizontal storage of fuel tanks is suitable for oversized rooms, the height of which does not allow working with lifting devices and allows storage and movement of products in only one tier.

In FIG. 1 shows a sequence of operations with an aircraft fuel tank.

I. Aircraft fuel tank 1 is removed from the aircraft of ship 2 and placed on a feeder trolley 3, and it is transported to a storage room.

II. In the range of the load-lifting device 4, the tank is lifted from the trolley-feeder with the hoist of the load-lifting device, and the freed trolley is driven away.

III. In the overload zone, lodging carts 5, taken from temporary storage places, are installed on the guides and connected to each other by a bar, and the fuel tank is loaded onto them, which is secured with ties and locks.

IV. Moving the lodgement trolley 5 from the overload zone to the storage location is carried out manually along the guides. At the place of storage, the camping carts are fixed with a locking mechanism.

The fuel tank is dispensed to the aircraft in the reverse order.

In FIG. 2, 3, 4 and 5 show a complex of deck storage and supply of aviation fuel tanks.

The aviation fuel tank 1 is immersed on the lodgement trolleys 5 (see. Fig. 3, 4, 5). The vertical rollers 7, the horizontal rollers 8, the couplers 9 and the lock 10 are attached to the housing 6 of the lodgement carriage. At the same time, the casing is a lodgement on which the aviation fuel tank is placed. The supporting surface of the body is glued with rubber. On the body are located: the rod mounting unit 11, connecting the cart during storage and transportation of the product, and the fixing unit of the lodgement trolley in a marching 12.

The coupler is intended for fastening the fuel tank to the cradle. As an example, flexible couplers were used in the design of the device (see RF patent No. 2509043), but any other means of restraint against displacement can be used.

The screed 9 consists of sections interconnected by axles and glued with rubber. One end of the coupler is stationary mounted on the body using the axis 13. The other end of the coupler is removable and is attached to the body with a lock 10. The lock is designed to fasten the coupler to the body of the truck, thereby pressing the fuel tank to the lodgement of the body of the truck.

The coupler lock has a lever 14, consisting of a fixed upper part and a rotary stop. From spontaneous opening, the lever is protected by a spring-loaded clip 15, in the closed position preventing it from turning. To release the aviation fuel tank from the mounting, it is necessary to press the clip upwards by hand, overcoming the force of the spring 16, and release the swivel stop. After that, turn the lock from the product until the stop comes out of engagement with the screed.

The lock is connected to the trolley case by means of an axis 17, strap 18, bolt 19 and nut 20. The strap, bolt and nut provide the ability to control the vertical distance from the trolley case.

Vertical rollers 7 are designed to move the cart along the guides. Horizontal rollers 8 are designed to hold the cart on the rails and prevent it from jamming when moving.

Each storage trolley is fixed at the storage location by a locking mechanism. The locking mechanism (see Fig. 4) consists of a screw 21, which is screwed into the base 22. At the end of the screw, a stop 23 is attached to the ball bearing. When the screw is screwed into the base, the stop abuts the locking unit of the lodgement trolley in a marching manner.

During storage and transportation, the fuel tanks of the cradle trolleys are connected to each other by a rod 24. The landing unit of the rod is inserted into the curly grooves of the attachment points 11 on the carts.

The guides 25, along which the lodging carts move from the storage place, are a welded construction of rolled metal and brackets, with which they are attached to the foundations. Foundations are designed for mounting rails to the deck. The guides are located along the transportation path of the fuel tanks and fall into the range of the lifting device. In the presence of coaming in the room and rolling through them the trolley-feeder 3 in the area of the hoist set additional guides 26 (see Fig. 2 and Fig. 2) /

The lifting device 4 in the room of aviation fuel tanks is designed to reload the product from the lodge-cart to the feeder trolley. It consists of: a beam 27, a foundation 28, a movable manual chain hoist with a travel blocking device 29, a stop 30 and a belt 31 (see Fig. 3). The beam is a welded construction of I-beam and brackets, with which it is attached to the foundations, which, in turn, is designed to mount the beam to the ceiling of the room. The emphasis is a bracket with a rubber shock absorber and is designed to limit the movement of the hoist along the beam. The belt is used for fixing the hoist by a mobile manual chain with a travel blocking device in a marching manner.

The advantages of this method of storage and supply are:

- the most effective way from the point of view of laying and using volume is a horizontal way of storage and transportation in a confined space;

- the ability to transport aviation fuel tanks from the storage location immediately to the feeder trolley, which allows for quick preparation of the product by forces of not more than two people;

- ensuring a high rate of supply of fuel tanks to aircraft;

- a combination of high speed of cargo handling with versatility in terms of the type of cargo carried (for example, by types of aviation fuel tanks), as the lodges can be made removable.
