Abstract

FIELD: artillery weapon. SUBSTANCE: loading system has a device for barrel elevation and lowering, device for shell orientation on the feeding line and an elevator with a drive for catching the shell. The device for shell orientation is made in the form of a spring-loaded rod hinge-joined to the floor installed on the rod axle, its upper end is connected to an intermediate lever hinge-joined to the gun breech. Mounted in the middle part of the rod is an electromagnetic lock engaging the rod to the lever and disengaging it from the lever, and guides with a movable carriage engageable with the rod springs installed along the guides. The carriage is hinge- joined to a connecting rod hinge-connected to the floor of the fighting compartment. The elevator with the drive is made in the form of a lead screw with a carriage moving along the rod. Installed on the carriage axle is a double-arm lever with a roller engageable with the shell case bottom. EFFECT: expanded field of application, reduced overall dimensions and mass of the loading system. 3 dwg

Description

 The invention relates to military equipment and can be used in large-caliber artillery installations.

 Known weapons charger (UK, application N 2150674 from 07/03/85), made in the form of a parallelogram mechanism by which the projectile is fed to the line of sending weapons. Shells in the fighting compartment are located horizontally with the warhead towards the center of the fighting compartment.

 The parallelogram mechanism is operated from an external drive. The design drawback is the presence of an additional energy source for the operation of the parallelogram mechanism and the large dimensions due to the irrational use of the volume of the fighting compartment due to the horizontal arrangement of shells.

 In a vertical loading system (US Patent No. 4,398,447), the gun is mounted above the ammunition storage cellar and is provided with a protective coating that moves along the azimuth along with the gun. The system includes a device for lifting the barrel in a vertical position and a device for vertical orientation of the projectile. In this case, the projectile is installed exactly against the breech of the gun. The system has a lift that captures the projectile and with the help of a drive device introduces it through the open bolt into the breech. To hold the shell in the breech there is a latch. After the release has been activated, the drive device leads the elevator out of the breech. After closing the shutter, the weapon is pointed and a shot is fired. After the shot, the device for lifting the barrel translates it into an intermediate inclined position, in which, with the shutter open, the spent sleeve is ejected.

 The design drawback is the limited area used due to the impossibility of loading the installation in a space limited from above (shelter, tunnel, under the bridge, overpass, etc.).

 The task of the invention is to reduce the size of the installation, simplifying the design, reducing weight, and also expanding the scope. The problem is solved in that in the known design of the loading system for the gun mount, containing a device for raising and lowering the barrel, a device for orienting the projectile on the sending line and an elevator gripping the projectile using the drive device, the device for orienting the projectile on the sending line is made in the form of a spring-loaded rods pivotally mounted on the floor of the fighting compartment. A lever is mounted on the axis of the rod, the upper end of which is pivotally connected to the intermediate lever, which is pivotally mounted on the breech of the gun. An electromagnetic stop is installed in the middle part of the rod, which engages and releases the rod with a lever. Guides are installed along the rod, on which a movable carriage is located, interacting with the rod springs, installed along the guides. The carriage is pivotally connected to a connecting rod mounted pivotally on the floor of the fighting compartment. The elevator with the drive device is made in the form of a lead screw with a carriage moving along the rod. A two-arm lever with rollers at the ends is installed on the axis of the carriage, one of which is mounted on the treadmill of the bar, and the other with the possibility of interaction with the bottom of the shell shell.

The proposed solution is illustrated by graphic materials, where in FIG. 1 depicts a loading system at the time the shelling starts. The gun and the loading mechanism are installed at an angle α ^° , where α ^° is the loading angle. In FIG. 2 shows the construction of an electromagnetic stopper; FIG. 3, the gun is installed at an angle β ^° , where β ^° is the ejection angle of the sleeve, and the loading mechanism is in the initial position.

 The loading system for the gun mount consists of a lower lever 1, one end of which is pivotally mounted on the axis of the rod 2, and the other on the intermediate lever 3. The intermediate lever 3 is pivotally mounted on the arm of the gun guard 4. The guides 5 are mounted on the rod (Fig. 2) along which the spring-loaded carriage 6 moves (Fig. 1). The carriage 6 is pivotally connected to the connecting rods 7, pivotally mounted on the floor of the fighting compartment. In the middle part of the rod 2, an electromagnet 8 is fixed (Fig. 2), the rod of which is pivotally connected to the clamp 9. The clamp 9 is mounted to interact with the stopper 10, which moves in the sleeve of the lower arm 1. On the rod 2 (Fig. 1) is rigidly fixed bracket 11 (Fig. 2) with a hole "a".

The lever drive operates as follows: in the initial position of the gun and the loading mechanism (Fig. 3), the electromagnet 8 (Fig. 2) is activated, the lever 9 rotates around the axis and presses the stopper 10, which goes into the hole "a" of the bracket 11. In this case the rod 2 and the lower arm 1 become one. With a vertical guidance drive, the gun from the angle of ejection of the sleeve β ^{° is} translated to the angle of loading α ^° .
In this case, due to the kinematic connection, the rod 2 sets the shot 12 (Fig. 1) to the loading line. The cycle of rotation of the gun and the loading mechanism occurs simultaneously. Then, the drive drive is triggered, the carriage 14 moves along the screw 15 and with the lever 16, shot 12 is sent to the breech of the gun. After charging, the electromagnet 8 (Fig. 2) is turned off and the rod under the action of the spring 13 (Fig. 1) returns to its original position.
