RU2498195C1 - Loader-transporter for self-propelled artillery-type weapon - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to military equipment, and namely to loaders-transporters for self-propelled artillery-type weapons (SAW). Loader-transporter includes wheeled or tracked chassis, ammunition, ammunition feed mechanism (AFM), and ammunition containers. AFM includes two working elements providing at least six degrees of freedom at movement of containers from loader-transporter to SAW and back. Containers comprise hatches for ammunition unloading under action of force of gravity.

EFFECT: invention allows reducing the time required for ammunition loading from a loader-transporter to SAW during firing.

Description

The invention relates to the field of military equipment and can be used in self-propelled artillery.

A well-known Swedish 155 - mm self-propelled gun "Bandanon 1A" with a tracked chassis, a tower with an ammunition store and loading mechanism mounted on it (GL Kholyavsky. Encyclopedia of armored vehicles. Fighting tracked vehicles. 1919-2000, Harvest, 2001, p. 260). The loading mechanism moves the ammunition magazine, for example, from a truck to a receiver on a self-propelled gun turret. When firing, the ammunition is fed into the gun from the store, with the full consumption of ammunition, the full store is set again.

The disadvantage of this self-propelled gun is the placement of the loading mechanism on the tower, which leads to a significant increase in weight and dimensions.

Closest to the claimed invention in terms of essential features is a transport-loading vehicle (armored carrier of ammunition) ХМ2002 for the American 155-mm self-propelled howitzer ХМ2001 "Kruseyder" - (GL Kholyavsky. Encyclopedia of armored vehicles. Combat tracked vehicles. 1919 - 2000 ., Harvest, 2001, p. 227). This transport-loading machine has a tracked chassis on which ammunition (shells and charges) are located, as well as a feeding mechanism (conveyor) for piece-wise movement of ammunition inside a self-propelled howitzer. The feed mechanism in the loading position is directly connected to the receiving device of the self-propelled howitzer.

The disadvantage of the prototype is the inability to fire when loading ammunition from a transport-loading machine due to significant movements of the self-propelled howitzer during firing, which can cause damage to the ammunition or the transport-loading machine itself.

The objective of the invention is to ensure the loading of ammunition from a transport - loading machine into a self-propelled artillery gun directly in the process of firing.

The problem is solved in that the ammunition in the transport-loading machine is placed in separate containers. Each container in its lower part is equipped with a hatch for unloading ammunition under the influence of their gravity. A feed mechanism is installed on the transport-loading machine, which has two working bodies for moving ammunition from the transport-loading machine to the receiver of a self-propelled artillery gun, and these working bodies move simultaneously and independently of each other, each of them has at least six degrees of freedom.

A new set of structural elements, as well as the presence of connections between them, allow, in particular, due to:

- placing ammunition in separate containers to move them from a transport-loading machine to a self-propelled artillery gun during the shooting process, excluding the time interval of direct installation of the container on the receiver of the self-propelled artillery gun;

- execution of the hatch in the lower part of each container to unload the ammunition at the receiving device under the action of their gravity;

- performing a feed mechanism with two working bodies, each of which has at least six degrees of freedom, to load ammunition into a self-propelled artillery gun simultaneously in two streams at any position relative to a transport-loading machine within the radius of action of the working bodies of the feed mechanism.

The invention is illustrated by drawings, in which Fig. 1 shows a self-propelled artillery gun and a transport and loading vehicle in a position for reloading ammunition, and Fig. 2 shows loaded projectile and charging containers.

On the transport and loading machine 1 (Fig. 1), charging containers 2 and projectile containers 3 are placed, as well as a feeding mechanism 4 with two working bodies 5 and 6. Self-propelled artillery gun 7 has a receiving device 8 in the aft for installation of containers 2 and 3. Charges 9 (FIG. 2) are placed in a container 2 provided with a hatch 10 for unloading them, and accordingly, shells 11 are placed in a container 3 with a hatch 12 for unloading them.

The process of loading ammunition from a transport-loading machine 1 into a self-propelled artillery gun 7 is as follows. The working bodies 5 and 6 of the feeding mechanism 4 move the containers 2 and 3 independently of each other to the receiving device 8, where they are fixed, for example by stoppers, and at the same time the hatches 10 and 12 are opened. After that, charges 9 through the hatch 10 and shells 11 through the hatch 12, under the influence of their gravity, enter the receiving device 8 and then inside the self-propelled artillery gun 7 in its warhead. With the full consumption of ammunition in containers 2 and 3, the latter are moved by the feed mechanism 4 back to the transport-loading machine 1 to its original place, and then the work cycle is repeated.

Claims (1)

A transport-loading machine for a self-propelled artillery gun, comprising a wheeled or tracked chassis with ammunition (shells and charges) placed on it and a feeding mechanism for moving ammunition from the transport-loading machine into a self-propelled artillery gun, characterized in that the ammunition is located in separate containers, each of which is equipped with a hatch for unloading ammunition under the influence of their gravity, and the feed mechanism has two working bodies, each of which provides at least six degree of freedom when moving containers from a transport-loading machine to a self-propelled artillery gun and vice versa.
