Abstract

The device for remote actuation of rocket launchers contains a metal frame, pins for mounting the frame to the ground. The frame is made of two welded X-shaped metal frames, connected by ties, on one of which there is a pressure lever with an elastic element, and on the other there is a pulley for directing the starting cord.

Description

The useful model belongs to the equipment, namely to devices for remote activation of rocket launchers for the purpose of safely establishing their ability to fire, namely grenade launchers "RPG-18", "RPG-22", "RPG-26", "RPG- 27", "RPG-28" and "PG-29".

When conducting forensic explosive technical examinations, where the objects of research are industrial explosive devices or ammunition, which include the above-mentioned rocket launchers, it is necessary to conduct expert experiments. They are carried out at landfills (blasting sites) using special explosive and technical equipment. Remote shooting is carried out under the conditions of a complete and comprehensive preliminary study of the rocket launcher and in the absence of signs of external interference in its design.

Known device (Ukrainian patent 123069, IPC B42 3/00, Device for remote activation of hand grenades and their detonators / O.A. Bukhanchenko, O.V. Kravchuk, O.P. Marchuk,

Zarechny A.V. (Ukraine); - MO and 201708062; statement 07/02/2017: Publ. 12.02.2018. Bul. Me3| for remote activation of manual fragmentation grenades and their detonators, which contains a metal frame, as well as pins for attaching the frame to the ground, on which there is a corner with a braking element for creating the initial tension of the cord, a corner with the formation of a supporting shelf and a groove for installing a check ring of a grenade detonator, two double-armed levers in supports connected by a tie, an adjustable safety frame, and the end of the frame is installed in front of the wall of the well, which is directed at it at an angle of 45". The disadvantages of the known device include the fact that there is no constructive possibility of installing a grenade launcher on it with a shot and its design is designed to perform highly specialized tasks.

The closest in terms of technical essence is a device for remotely activating rocket-propelled grenade launchers with shots (V.I. Pashchenko. Methods of destroying ammunition by blasting. Instruction / V.I. Pashchenko, R.L. Khomko.; Kyiv - 2007. - 47s| , containing a frame on which a rocket-propelled grenade launcher is fixed. The principle of remote pressure on the trigger of the grenade launcher is based on the influence of gravity. Under the frame, there is a load on a belt with a bracket that covers the grenade launcher in the area of the launcher. The load is located on a retractable stand, which is attached to starter cord When pulling out the retractable starter cord

With the stand, the cargo falls from it and the bracket activates the trigger - a rocket-propelled grenade shot is fired.

The disadvantages of the known device include the fact that when pulling the trigger cord with a retractable stand, the load can also shift, changing the position of the clip in the area of the trigger element, which can lead to a failure to fire or a shot in an unspecified direction, which in turn will pose a direct threat to life and the health of those present.

The useful model is based on the task of ensuring the effective operation of the launcher and safe remote activation of rocket launchers in order to establish their ability to fire.

The task is solved by the fact that the device for remote activation of rocket launchers in order to establish their ability to fire contains a frame made of two welded X-shaped metal frames connected by ties, on one of which there is a pressure lever with an elastic element and on the other, there is a pulley for directing the starting cord, as well as pins for attaching the device to the ground.

The design parameters of the lever of the device for remote activation of rocket launchers in order to ensure the effective operation of the launcher are selected under the following conditions:

IL 2-2.5-3, where I is the length of the arm of the lever for pressing the trigger;

Y" is the length of the arm of the lever with an elastic element.

The technical result consists in obtaining fault-free operation of the launcher and safe implementation of remote activation of rocket launchers during expert experiments with the aim of establishing their ability to fire.

Drawings explain the essence of a useful model.

In Fig. 1 - main view of the device.

In Fig. 2 - side view of the device.

On Fig. With and Fig. 4 - a general view of a working sample of the device.

The design of the device for remote activation of rocket launchers is shown in Fig. 1 and Fig. 2: it consists of two welded X-shaped metal frames 1 connected by ties 2, 3, 4, 5, 6. A lever 7 is installed on the upper tie 5, connected by an elastic element 8 to the lower tie 6. On the middle tie A pulley 9 is installed to direct the launch cord 10. The device for remote activation of rocket launchers is fixed to the ground 11 with the help of pins 12. A rocket launcher with a shot 13 is installed on the frame 1 so that the launch element 14 is on top at the level of the lever 7.

The device works as follows: a rocket-propelled grenade launcher with a shot of 13 is attached to the frame 1 with the help of plastic clamps. To prevent an uncontrolled explosion, the trigger cord 10 is unwound to a safe detonation distance, passed through the pulley 9 and attached to the lever 7 with a carabiner. Specialists retreat to a safe distance and are placed in a place designated for this (trench, bunker). Next, the trigger cord 10 is pulled out, which activates the lever 7, which presses the trigger element 14 and the shot is fired.

In order to test the performance of the proposed device, a working design of the device for remote activation of grenade launchers with shots for the ability to work and explode was made, which is shown in Fig. With and Fig. 4 and range experimental shootings were conducted.

As a result of the inspection, it was established that the experimental firings were carried out safely with 100 95-th firing efficiency.

Thus, the proposed useful model allows safe and effective remote activation of rocket launchers in order to determine their firing capability.
