Abstract

FIELD: military equipment, applicable for automatic removal of signal on producing of a shot and beginning of recoil of the artillery gun barrel, and for transmission of it, in particular, to the control equipment of adjustable and guided artillery projectiles.

SUBSTANCE: the artillery gun swinging part has a cradle, protection enclosure, recoil indicator, which consists of a bracket, spring-loaded lever and a transducer installed on the bracket. The recoil indicator is fastened to the cradle with the aid of a catch and clamp bolts. The swinging part may be quickly mounted and dismantled on the artillery gun.

EFFECT: enhanced reliability and accuracy of operation of the control equipment.

Description

The invention relates to the field of military equipment and is intended to automatically remove a signal about the firing of a shot and the start of a rollback of an artillery gun barrel.

Known swinging part of the artillery gun (1), adopted for the prototype, containing a cradle, a fence, a rollback indicator, consisting of a ruler with a cradle placed on it.

When the barrel rolls back, the breech rolls onto the creep of the rollback pointer and shifts it toward the rollback along the ruler.

The disadvantages of this design pointer rollback are:

- the inability to automatically remove the signal about the production of a shot and the beginning of the rollback;

- the need after each shot to move the crawler manually to its original position.

The task to which the invention is directed is to automatically remove a signal about firing a shot and starting to roll back the barrel of an artillery gun and transmit it, in particular, to the control equipment of adjustable and guided artillery shells, which allows to increase the reliability and accuracy of the control equipment being adjusted and controlled artillery shells.

The technical result is the creation of a swinging part of an artillery gun, providing automated removal of a signal about the production of a shot from an artillery gun.

The claimed technical result is achieved by the fact that:

- in the design of the swinging part of the artillery gun containing the cradle, fencing, rollback indicator, the latter is made in the form of an electromechanical sensor with a movable rod and a spring-loaded lever, while the sensor is mounted on a quick-detachable bracket mounted on the cradle of the gun, with the ability to automatically record a signal about firing a shot and the beginning of the rollback.

The signal generated from the sensor is transmitted to the equipment, in particular, for switching on the control devices for adjustable and guided artillery shells.

The essence of the proposed solution is illustrated by drawings, where:

figure 1 is a General view of the device;

figure 2 is a view along section aa in figure 1;

figure 3 is a view along section BB in figure 1.

The swinging part of the artillery as applied to the self-propelled howitzer M109AZ contains a cradle 1 (see figure 1), a recoil indicator, which consists of a hook 17 (see figure 2), pinch bolts 9, 10, 14 (see figure 1) , cable 13, bracket 2, on which the sensor 11 is mounted with a switch 12, a lever 3, a spring 4, a sleeve 5, an axis 8, a washer 6 and a cotter pin 7.

The device operates as follows.

In the initial position before the shot, the rod 16 of the sensor 11 is pressed by the lever 3, the electric circuit is open. When fired, after rolling back the barrel with breech 15, the lever 3 under the action of the spring 4 rotates all the way into the bracket 2. Due to the bevel, it releases the rod 16 of the sensor 11, as a result of which the electric circuit is closed and a signal is generated that the barrel with breech 15 has gone in rollback, that is, a shot occurred.

When rolling back, the barrel with breech 15 rolls onto the lever 3 and rotates it. In this case, the lever shelf 3 presses the rod 16 of the sensor 11, as a result of which the electric circuit opens, which indicates that the barrel with breech 15 has returned to its original position.

Currently, a prototype of the swinging part of the artillery gun has been made, which is being tested.

Claims (1)

The swinging part of the artillery gun, containing a cradle, a fence and a recoil indicator, characterized in that for the automated signal collection about the firing of a shot and the beginning of the recoil of the gun barrel, the recoil indicator is made in the form of an electromechanical sensor with a movable rod and a spring-loaded lever, while the sensor is mounted on a quick-detachable bracket mounted on the cradle of the gun.
