Description

The invention relates to military equipment, in particular to the installation of weapons on vehicles.

Known weapons installation (see patent RU No. 2256138, F41F 23/00, 27/22, 07/10/2005, No. 19), taken as an analogue. The installation contains a lower and upper machine, a cradle with trunnions and a weapon installed on it, including a bolt with protrusions of a combat cock, a release lever and a sear, a balancing mechanism, a pivoting and lifting mechanism in the form of a channel-shaped crossbar on the back of the cradle with control handles, the cradle brake, including traction with a spring and a fuse, a mechanical fire control system, a braking system with brake pads.

The disadvantage of a mechanical analog descent-locking system is:

- during the descent, a moment arises leading to the deviation of the installation guidance from the aiming line, which reduces the accuracy of shooting.

Known weapons installation (see patent RU No. 2419056, F41A 23/00, F41A 27/22, 05/20/2011, No. 14), taken as a prototype. The installation contains a lower and upper machine, a cradle with trunnions and a weapon installed on it, including a bolt with protrusions of a combat cock, a release lever and a sear, a balancing mechanism, a rotary and lifting mechanism in the form of a channel-shaped crossbar on the back of the cradle with control handles, the cradle brake, including sector with brake surfaces, screw clamp with screw and nut and brake lever, trigger mechanism including rod with spring and fuse, mechanical fire control system, t brake pads. The braking system is made in a vertical plane, the control handle or one of them has an electric button and an arm on which the lever is mounted, connected to the trigger lever and a spring-loaded lead of a screw clamp with cables through a rocker with regulators of their strokes. The installation has an electromagnet of the brake system mounted on a channel-shaped crossbar with the possibility of interaction with a lead of a screw clamp. The installation is equipped with an electric trigger with the ability to interact with the sear.

The disadvantage of the mechanical system of descent-locking of the prototype devices are:

- the lack of protection of the manual descent traction from accidental impacts during operation with the installation;

- the lack of protection of the cables of the descent-locking system from mechanical damage and the possible collapse of the cables at the points of fastenings and bends and, accordingly, increased efforts on the trigger handle;

- the difficulty of adjusting the tension of the cables during operation.

The objective of the invention is to increase the combat effectiveness of a weapons installation.

The technical result obtained by carrying out the invention is:

- reliable protection of the manual descent rod from accidental impacts during operation with the installation due to a fuse installed between the manual descent rod and the right control lever;

- improving the reliability of the installation due to the additional protection of the cables and the absence of fastenings;

- simplifying the adjustment of the descent-locking system by introducing adjusting screws.

The specified technical result is achieved by the fact that in the descent-locking system of the weapon system containing a rotary and lifting mechanism in the form of a channel-shaped bar on the back of the cradle with control levers, the cradle brake includes a sector with brake surfaces, a screw clamp with a screw, nut and brake lever , the trigger mechanism, including traction with a spring and a fuse, a mechanical fire control system, a braking system with brake pads, control levers, or one of them, have the bracket on which the rod is mounted, connected via a cable through the rocker with regulators of their strokes to the trigger lever and the spring-loaded lead of the screw clamp, the new one is that the fuse is located between the control lever handle and the rod with the possibility of movement along the control lever handle, the beam is rigidly fixed relative to the rod , cable shirts are dressed on top of cables, fixed in adjusting screws installed with the ability to move, armored hoses are dressed on top of cable shirts.

The invention is illustrated by drawings.

In FIG. 1 shows a descent-lock system (top view);

in FIG. 2 - trigger device;

in FIG. 3 - locking mechanism device;

in FIG. 4 - locking mechanism device (view A);

in FIG. 5 - transition block;

in FIG. 6 - draft with a safety lock and a control lever.

The system of descent-locking weapons installation contains a rotary and lifting mechanism 1 in the form of a channel-shaped crossbar. A rod 3 is attached to the control lever 2. The beam 4 is fixed in the rod 3 and connected to the cables 5 and 6. The cables pass through the adapter block 7 with a roller 8 and grease. The end of the cable 5 is mounted on the lever 9 mounted on the bracket 10 with the possibility of interaction with the spring 11, connected with the lever 12 of the trigger mechanism 13 of the machine gun 14. On the cable 5 is put on the shirt of the cable 15, installed in the grooves of the adjustment screws 16 and 17, mounted in the adapter block 7 and the bracket 10, respectively, with the possibility of movement from one or both ends. The cable jacket 15 is located inside the armored hose 18, which is rigidly fixed on the adjustment screws 16 and 17. The end of the cable 6 is sealed in a spring-loaded lead 19. A cable 20 is put on the cable 6, installed in the grooves of the adjustment screws 21 and 22, fixed in the adapter block 7 and the lever brakes 23, respectively, with the ability to move from one or both ends. The cable jacket 15 is located inside the armored hose 24, rigidly fixed to the adjusting screw 19 and the locking mechanism housing 25. The spring-loaded lead 19 is fixed in the brake lever 23 with the possibility of axial movement and has the ability to interact with the spring 26 and the brake sleeve 27. The fuse 28 is installed between the rod 3 and control lever 2. Fuse 28 with a groove 29 is fixed with a nut 30, which has the ability to move along the control lever.

The device operates as follows

Having unscrewed the nut 30, we release the fuse 28 from the engagement with the groove 29 with the rod 3. When the rod 3 is pressed in the direction B, the rod 3 acts on the beam 4, which acts on the cables 5 and 6. The cable 5 moves the lever 9 in the direction B. The lever 9 acts on the lever 12 of the trigger 13 of the machine gun 14 and moves it in the direction G. The trigger 13 as a result acts on the sear 31 of the machine gun 14 and fires. The cable 6 moves the spring-loaded leash 19 in the direction D, which, turning the brake sleeve 27, brakes the installation in a vertical plane.

After releasing the rod 3 from the force, the springs 11 and 26 respectively return the lever 9 and the spring-loaded lead 19 to the initial position, simultaneously through the cables 5 and 6 and the rocker 4 acting on the rod 3, returning the rod 3 to its original position. Having connected the fuse 28 to the rod 3 with the groove 29, fix it with the nut 30.
