Description

The utility model relates to equipment for working out the construction of mechanisms and machines, and can be used in working out the design and joint work of two conveyors for loading the tank’s guns: one located in the fighting compartment of the tank, and the other crazy one.

Known automatic loaders (A3) of tank guns of basically two types.

In the T-72, T-80 and T-90 tanks (see Murakhovsky, p. 115, 121, 123) Soviet and Russian-made A3s are used, in which a mechanized combat unit in a rotating conveyor with trays is located around the perimeter of the fighting compartment inside the tank.

Another well-known type is the gobble A3 (see RF patent No. 2195617, MKI F 41 A 9 (38). The machine is made in the form of a transport-loading container, removably mounted on the rear wall of the tower. Removing the loader and shells into the transport-loading container allows use extended armor-piercing-projectile shells of increased power, however, in such an A3 there is a limited number of shots, the remaining part of the shots necessary for fighting is located in the hull, access to them is difficult, and their loading is carried out To increase the military-technical efficiency of the tank’s fighting compartment by automating the loading of the tank gun with shots of the entire ammunition placed in the tank and the effective use of ammunition shots, based on the tactical requirements of the combat stop, the “Combat compartment of the tank" according to RF patent No. 2215965 can be used The technical result is achieved

in that, a double-conveyor A3 tank gun is used. In the fighting compartment of the tank, which contains an armored turret, a transport-loading container with an A3 equipped with a magazine for firing shots mounted on its rear, an additional A3 is installed in the tank turret, equipped with a carousel-type conveyor located on the tank bottom and located behind the breech of the gun in the lower zone parts of it are a mechanism for raising shots, while for loading the guns, a unloading mechanism common to both of the aforementioned A3 is used, which is made in a transport-loading container. The options for optimal placement of shots of various types are shown.

Since the aforementioned A3s are complex in design and very high demands are placed on them for reliability and safety, stands are used to refine the kinematics, dynamics and design of the main elements.

The well-known "Stand for a turret automatic loading machine for a tank gun" (see RF patent No. 35877 for a utility model), taken as a prototype of the claimed technical solution.

The stand is equipped with a supporting table, on which the fuel tank and the tank cannon with the breech, charging chamber and bolt are removably mounted, placed relative to each other in accordance with their installation - on the tank, the fuel tank is formed by the front and rear walls connected in the lower part along the longitudinal axis of which receiving tray and guide chute, forming the base.

The conveyor is designed to accommodate a variable number of cartridges with shots, the stand is equipped with a control system, electrical equipment A3 and air control and fixing photo and video equipment of the kinematic links A3.

A disadvantage of the well-known stand is that it does not solve the problem of developing a dual-conveyor A3.

In addition, the stand does not allow simulating loading in the actual operation of the tank, including on rough terrain, where loading is done with the roll of the tank on board or with roll and trim.

A real useful model solves the problem of developing the design and collaboration of a two-conveyor A3: a reckoned submachine gun and a submachine gun located in the fighting compartment.

The problem is solved in that the stand is additionally equipped with a manual mechanism for lifting cartridges with mock shots, set in a position corresponding to the placement in the fighting compartment of the tank with the possibility of interacting with the standard cartridge when loading an additional automatic loader from the conveyor, or with a through cartridge when loading from the conveyor of an overloaded machine loading, and for loading the gun with mock-ups of shots, the unloading mechanism, which is placed in the vehicle a sports-loading container, wherein the lifting mechanism is installed in the window of the supporting table and mounted on the wall of the transport-loading container with the possibility of turning on adjustable brackets and ensuring alignment of the shot in the raised cassette with the barrel channel at the loading angles, and the stand is equipped with a device for changing the loading angle, made in the form of a p-shaped bracket, rigidly fixed to the supporting table, and an adjusting screw, which is installed in the bracket with the possibility of interaction with the breech shki.

On the carrier table opposite the shutter wedge window and on the cut of the gun barrel, seats were made for fastening high-speed cameras.

The supporting table is equipped with devices for exhibiting angles of roll and trim of the tank.

The analysis of the main distinguishing features showed that:

- the inclusion in the stand’s construction of the manual cassette lifting mechanism installed in a position corresponding to the placement in the tank’s fighting compartment with the possibility of interacting with the standard cassette when loading an additional automatic charging machine from the conveyor, or with a through cartridge when loading an ambitious automatic charging device from the conveyor, made it possible to work out the design of the two-conveyor automatic loader with increased military-technical efficiency;

the installation of a manual mechanism for lifting the cassettes in the window of the supporting table and fixing it on the wall of the transport-loading container with the possibility of a turn on the adjustable arms, ensured alignment of the shot in the raised cassette with the barrel channel at different loading angles;

- the use of the adjusting screw installed in the U-shaped bracket, allowed to test the stand at different loading angles to optimize its value;

- the use for loading guns of a uniform for both automatic loaders loading mechanism, which is placed in a transport-loading container, has simplified the design and increased reliability;

- the use of high-speed video cameras made it possible to accurately capture, in real time, the trajectory of the shot in the area of the bolt wedge and relative to the axis of the barrel channel;

- supply of the supporting table with devices for exhibiting angles of roll and trim of the tank provided the opportunity to work out the loading cycle, simulating the operation of the tank on uneven terrain. The utility model is illustrated by drawings, which depict:

- figure 1 is a side view of the stand;

- figure 2 is a top view of the stand;

- figure 3 is a view of a section of the barrel of the gun with the installed video camera.

The stand for testing the dual-conveyor A3 (see figure 1, 2) includes the following elements.

The supporting table 1 on the supporting posts 2 is equipped with devices for displaying the angles of heel and trim of the tank, which can be made, for example, in the form of jack supports 3. To the vertical wall 4 and on the supporting platforms 5 are fixed TZK 6 of the frantic A3, in which the tape endless conveyor 7 and transfer mechanism 8. In wall 4 there is a window “A” for passage of shots from the fired A3, on the adjustable brackets 9 in the window “B” of the supporting table 1 there is a mechanism 10 for lifting the cartridge with mock-ups of shots, which is installed in the position, respectively to be placed in the fighting compartment of a tank with an A3 carousel conveyor. Between the window "A" and the mechanism 10 is installed a removable guide 11, which is intended for the direction of the shot when working off the fired A3 and for the direction of the rammer (not shown in Fig.) When working out the carousel A3. The specified mechanism 10 is made with the possibility of interaction with the standard cartridge 12 of the carousel A3 or with the passage (guide) cartridge 13 when practicing the crazy A3. The gun 14 is installed on the supporting table 1 in the pins with the help of brackets 15 in accordance with its installation relative to the fuel tank 6 on the tank. The stand is equipped with a device for changing the loading angle in the form of a p-shaped bracket 16, which is rigidly fixed to the supporting table 1 and is equipped with an adjusting screw 17. installed with the possibility of interaction with the breech of the gun 14. The mechanism 10 is fixed with the possibility of rotation on the brackets 9 to ensure alignment of the shot in a raised cartridge 12 with the barrel of the gun 14 at different loading angles.

On the supporting table 1 opposite the window "B" under the wedge of the shutter of the gun 14 and at the cut of the barrel on the bracket 18 (see figure 3), seats were made for fixing high-speed cameras 19.

Work

The stand works in two modes.

1. The development of the carousel A3.

The guide 11 for the rammer is pre-installed. The mechanism 10 raises the standard cartridge 12 to the position of sending the projectile or charge, after which the control system of the stand provides an automatic cycle of sending the projectile or charge into the charging chamber of the gun 14 by the sending mechanism 8, which is fixed by high-speed video cameras 19. At the same time, the output of the rammer to the starting position is controlled, sending , the operation of the corresponding sensors, the return of the rammer to its original position, speed and acceleration are measured.

2. Testing the loading cycle of the crazy A3.

Pre-installed guide 11 for a shot from a frantic A3. The mechanism 10 raises the passage (guide) cassette 13 in the position of the direction of the shot from the frantic A3. After that, the control system of the stand provides an automatic cycle of sending out of the infested A3 with the sending mechanism 8. At the same time, the same parameters are adjusted and fixed as when working out the carousel A3.

At the same time, in both modes of operation of the stand, devices displaying angles of heel and trim imitate the operation of the tank on uneven terrain.

Thus, this useful model solved the task of developing the design and joint work of the two-conveyor A3: an ammunition machine and a machine located in the fighting compartment.
