Description

This utility model relates to medium-caliber rapid-fire naval artillery mounts. An integral part of the shipborne artillery mount is an ammunition store located under the artillery mount, usually made in the form of a horizontal conveyor or a rotating drum.

The priority direction of the development of rapid-fire naval artillery is the introduction of an automatic system into the composition of the drum-type ammunition store, which ensures the supply of artillery shots to the magazine drum without interruption in firing.

Known is a drum-type ammunition store for a shipborne artillery installation, which is chosen as a prototype of the claimed device (see RF patent for invention No. 2607700 "Shipboard artillery installation shop", publ. 10.01.2017).

The known shop of the ship's artillery installation contains a drum located under the machine of this installation, which is made with slots for shots, a system for automatic feeding of shots to the slots of the drum and two elevators attached to the machine with a two-way supply of ammunition to the machine. In this case, the drum is located between the elevators and is connected to the machine by means of an annular support provided with a rotation drive, fixed on the bottom of the machine, ensuring that the axes of rotation of this drum and the machine are aligned. Feeders are located in the cavities of the drum, ensuring that the shot enters into each cavity in the axial direction and exits from it in the radial direction under the action of the feeder, driven by the rotation of the drum. The system of automatic feeding of shots to the drum slots is, in the first version, a periodic-action hoist made with the possibility of lifting one artillery shot in one stroke. In the second version, the system for automatic feeding of shots to the drum slots contains a loading rotor located under the drum and movably connected to the machine with slots for shots, which is equipped with an autonomous turning drive and a lift capable of loading into the drum from a previously loaded loading rotor all ammunition.

In the prototype, it is possible, after braking the loading rotor, to equip it with shots, to combine the nests of the drum with the nests of the rotor and move all the shots into the drum with a hoist, and the possibility of repeated repetition of these operations is beyond doubt.

Along with the positive technical result that can be obtained by implementing the technical solutions of the prototype, the prototype of the claimed store has drawbacks, the main one of which is the inevitability of periodic breaks in firing to restore the spent ammunition in the drum, and the frequency of these breaks is due to the insufficient drum capacity.

Elimination of the indicated disadvantage of the prototype will enhance the positive effect of the system of automatic feeding of shots to the drum slots, and will make it possible to switch to a deserted firing technology.

The technical result, which can be obtained by implementing the claimed utility model, is that in the process of equipping the drum with artillery shots, the firing is not interrupted, the ammunition of shots ready for automatic firing increases significantly, and the moment of inertia of the rotating part of the ship's artillery installation and the dynamic load on horizontal guidance drive, which ultimately will reduce the dynamic error of the drive and increase the accuracy of shooting.

To achieve this technical result in a well-known ammunition store, which includes a central drum located under the rotary machine of the ship's artillery installation, made with slots for shots, two elevators attached to the rotary machine providing two-way feed of shots to this machine, and a system for automatic feeding of shots to the slots the central drum, and this drum is located between the elevators, according to the claimed utility model, an external drum with nests for shots is introduced into this store, and a system of automatic feeding of shots to the nests of the outer drum is introduced, which, with a larger diameter, has the same capacity as the central drum and is located concentrically central drum in such a way that the central drum is inside the outer drum, and two elevators are located in the annular gap between these drums, in addition, the central and outer drums are installed on a single annular along a gate support, which contains one stationary ring and two movable rings, mated by means of rolling elements with a stationary ring and each made with a gear rim, respectively, of internal and external engagement, these drums are equipped with a drive for the uniform rotation of these drums relative to the rotary machine, containing two corresponding gear motors , are equipped with valves that hold shots in the cavities of these drums, and feeders, which are located in these cavities with the provision of entry into the cavities of shots fed in the axial direction from below by the mentioned automatic feeding systems, and exit from the cavities in the radial direction into the annular gap between these drums under by the action of these feeders, driven by the rotation of these drums relative to the rotary machine, the stationary ring of a single annular rotary support and the gear motors of the rotation drive of these drums are fixed in a suspension fixedly connected to the base of the ship's artillery rian installation, each elevator is equipped with a guide vane, which is installed in the annular gap between these drums to keep the shots in a vertical position, moved by the feeders to the corresponding elevator, and both systems for automatic feeding of shots to the slots of the central and outer drums contain each elevator and a bogie storage conveyor, the load-carrying carts of which are equipped with clips for shots, these conveyors are located under the central and outer drums in the under-deck room of the carrier of this installation, one branch of the traction chain in these conveyors is straight, in the other branch, which has the shape of an arc, the clips of the load-carrying carts are in alignment with nests the corresponding drum, with each elevator equipped with a fork-type working body and installed with the possibility of moving shots from the arc-shaped branch of the traction chain of this conveyor into the slots of the corresponding drum.

In the ammunition store, both systems of automatic feeding of shots to the sockets of the central and outer drums can each also contain a multi-row step conveyor, which also performs the function of a mechanized warehouse, installed in the under-deck room of the carrier of the ship's artillery installation with the provision of a step feed of shots placed in it ready for automatic firing into the casings of the straight branch the pulling chain of the respective trolley conveyor.

The claimed ammunition store for a rapid-fire shipborne artillery mount has new technical properties that are absent in the known prototype.

Essential in the claimed store is that it has two concentrically arranged drums with sockets for shots and two systems for automatic feeding of shots to these drums, each of which contains a storage, a hoist and a mechanized warehouse, which significantly increases the ammunition of artillery shots ready for automatic firing.

Duplication in the claimed store of its component parts allows you to combine operations, for example, to perform firing, consuming the ammunition of the central drum, at the same time to brake the outer drum to equip it with shots from its own storage, and at the same time to equip the storage of the central drum with shots from the corresponding storage.

The alternation of drums in the performance of the above operations ensures the continuity of firing and the safety of equipment with the shots of the next drum.

It is also essential in the claimed store that a single annular rotary support, on which two drums are installed, and the drives for rotation of the movable rings of this support are fixed in a suspension fixedly connected to the base of the ship's artillery installation. This technical solution significantly reduces the moment of inertia of the rotating part of the artillery mount and the dynamic load on the horizontal guidance drive, which ultimately reduces the dynamic error of the drive and increases the firing accuracy.

The claimed technical solution, while retaining the advantages of the prototype, with the totality of its essential features, increases the tactical and technical characteristics and the degree of automation of the ship's artillery installation, creates conditions for the introduction of unmanned firing technologies.

Analysis of the existing scientific, technical and patent information showed the unknown of the proposed set of essential distinctive features. Some essential features were also unknown. Thus, the claimed utility model can be considered as meeting the "novelty" criterion of patentability.

In the claimed device, there is an unconventional solution to a technical problem, namely, two drums having the same capacity are arranged concentrically to one another in such a way that one of them is inside the other, and the two elevators with which these drums interact are in the annular gap between drums, which made it possible to divide the entire ammunition into two parts and continuously replenish them in the process of firing.

An unconventional technical solution is also to fix in the suspension, fixedly connected to the base of the ship's artillery mount, a single annular rotary support, on which two drums are installed, and gear motors for the rotation drive of the movable rings of this support, which reduces dynamic loads on the horizontal guidance drive and increases accuracy shooting.
