RU231257U1 - Unified extractor - Google Patents

Abstract

The utility model relates to the field of artillery weapons and can be used in units for technical maintenance and repair of missile and artillery weapons samples when restoring faulty weapons. The relevance and purpose of developing the proposed utility model are due to the need to optimize the composition of the technological equipment included in the PSTOR for technical maintenance, diagnostics and repair of artillery weapons, which will allow solving the scientific contradiction that has developed in practice, consisting in the constantly increasing requirements for weapons in terms of maintainability, on the one hand, and the PSTOR tool base that has remained at the same level, on the other.

The objectives of the development of the proposed utility model are:

- increasing the maintainability of the artillery part of multiple launch rocket systems (MLRS) and barrel artillery;

- improving the safety of work on the restoration of weapons when accepting samples of missile and artillery weapons (RAW) for repair at damaged vehicle assembly points (DMV);

- improving the tool base of unified repair and technical platforms (RTP) by including in their composition a technical solution aimed at implementing a non-firing method of unloading artillery weapons.

The stated goals are achieved by developing a unified extractor that allows for the safe unloading of artillery weapons.

The technical result and the set goal are achieved due to the fact that the proposed utility model can be implemented in the form of a design technical solution consisting of the following elements: replaceable freely rotating centering rings used for a caliber from 100 to 203 mm inclusive, the fixation and rotation of which is carried out due to pins for a screwdriver slot and grooves, an adapter that allows for a connection by means of a thread with a standard rod, which is part of a single set of spare tools and accessories for a RAV sample, a cylinder made of a thick-walled pipe, the outer diameter of which is 83 mm, and the wall thickness is 12 mm, which allows the product to have high strength indicators.

The implementation of the non-firing method of unloading an artillery weapon using the unified extractor we offer is carried out in accordance with the algorithm presented below.

Algorithm for unloading an artillery gun using a unified extractor.

1. In accordance with the caliber of the artillery weapon, it is necessary to install replaceable centering rings by fixing the pins in the grooves located in the cylinder.

2. Using the threaded connection on the adapter, connect the extractor to the standard rod;

3. Place the unified extractor assembly into the barrel of the artillery gun from the muzzle of the gun. In case of unloading the MLRS model, installation is carried out from the cabin of the combat vehicle. In this case, the chamfer on the cylinder of the unified extractor contacts the ogive of the projectile.

4. Using careful blows of a sledgehammer on the rod, push the projectile towards the breech of the artillery gun; to avoid damaging the rod of the swab, strike the rod through a wooden spacer.

Thus, the proposed unified extractor can be included in the tool base of the RTP and the 1I41 control and inspection machine in order to implement a non-firing method of unloading artillery weapons at the SPPM.

Description

The utility model relates to the field of artillery weapons and can be used in units for the technical maintenance and repair of missile and artillery weapons when restoring faulty weapons.

Various design technical solutions are known, intended for unloading artillery guns without firing, presented in [1-3].

The listed devices have a number of disadvantages, primarily related to the fact that the technology for extracting a projectile from the barrel bore with their help is not simple, requires economic costs and is associated with certain disadvantages, such as:

- extracting a projectile from the barrel requires the presence in the design of a mechanical discharger [1] of guide bushings and a rod, as well as devices that attach part of the discharger to the muzzle brake;

- the design implemented in [2] contains a hydraulic system consisting of high-pressure connecting hoses, a hydraulic pump, a container for placing hydraulic oil, a distribution device, which significantly limits the possibility of using the hydraulic ejector [2] in field conditions;

- the design of the extractor developed in [3] includes a neodymium magnet, the production of which requires certain economic costs;

- existing technical solutions require additional space to accommodate mobile maintenance and repair equipment (MSRE) in the tool base, which is difficult, since the possibility of equipping the MRE with additional technological equipment is limited by the working space of the van body and the load capacity of the base chassis.

The relevance and purpose of developing the proposed utility model are determined by the need to optimize the composition of the technological equipment included in the PSTOR for technical maintenance, diagnostics and repair of artillery weapons, which will allow solving the scientific contradiction that has developed in practice, consisting in the constantly increasing requirements for weapons in terms of maintainability, on the one hand, and the PSTOR tool base remaining at the same level, on the other.

The objectives of the development of the proposed utility model are:

- increasing the maintainability of the artillery part of multiple launch rocket systems (MLRS) and barrel artillery;

- improving the safety of work on the restoration of weapons when accepting samples of missile and artillery weapons (RAW) for repair at damaged vehicle assembly points (DMV);

- improving the tool base of unified repair and technical platforms (RTP) by including in their composition a technical solution aimed at implementing a non-firing method of unloading artillery weapons.

The stated goals are achieved by developing a unified extractor that allows for the safe unloading of artillery weapons.

The use of the utility model we offer in the restoration of RAVs has a number of advantages:

- the device does not contain complex pneumatic and hydraulic systems and is highly reliable;

- the proposed utility model can be used for artillery weapons with a caliber of 100 to 203 mm.

The technical result and the set goal are achieved due to the fact that the utility model proposed by us, shown in Fig. 1 (Fig. 1 - General view of the unified extractor), can be made in the form of a unified extractor containing an adapter made with the possibility of a threaded connection with a standard rod, a cylinder made of a thick-walled pipe, the outer diameter of which is 83 mm, and the wall thickness is 12 mm, while the extractor is made with the possibility of installing replaceable freely rotating centering rings used for a caliber from 100 mm to 203 mm inclusive, the fixation and rotation of which is carried out due to pins for a screwdriver slot and grooves.

The implementation of the non-firing method of unloading an artillery weapon using the unified extractor we offer is carried out in accordance with the algorithm presented below.

Algorithm for unloading an artillery gun using a unified extractor.

1. In accordance with the caliber of the artillery weapon, it is necessary to install replaceable centering rings 1 by fixing pins 2 in grooves 5 located in cylinder 3.

2. Using threaded connection 6 on adapter 4 (Fig. 2), connect the extractor (Fig. 1) to the standard rod 7;

3. Place the unified extractor assembly into the barrel bore of the artillery gun from the muzzle side of the gun. In case of unloading the MLRS model, installation is carried out from the side of the combat vehicle cabin. In this case, the chamfer on the cylinder 3 of the unified extractor contacts the ogive part of the projectile 8.

4. Using careful blows of a sledgehammer on the rod, push the projectile towards the breech of the artillery gun; to avoid damaging the rod of the sledgehammer 7, strike the rod through a wooden spacer.

Thus, the unified extractor we propose can be included in the tool base of the RTP and the 1I41 control and inspection machine in order to implement a non-firing method of unloading artillery weapons at the SPPM.
