RU191092U1 - UNIFIED DEVICE FOR EXTENSION OF BARS OF PRODUCTS 2A46, 2A46 M, 2A75 - Google Patents

Abstract

The utility model relates to artillery weapons and can be used at repair facilities for monitoring the technical condition, carrying out repairs and numbered types of technical maintenance of products 2A46, 2A46 M, 2A75 to perform artificial rollback, in order to check the condition and operation of the accelerator, the gap between the breech and copier , the state of the buffers, the inner surface of the knurling cylinder and the outer surface of the rods of recoil devices. The purpose of the utility model is to unify the devices for pulling ya barrels of products 2A46, 2A46M, 2A75. The technical result consists in changing the composition of the group set of spare tools and accessories for products 2A46, 2A46 M, 2A75 by replacing standard devices for pulling trunks with one unified. Unified device for pulling trunks of products 2A46, 2A46 M , 2A75 is made in the form of a constructive solution consisting of a support, a sleeve, a screw, two bolts. Essence: attachment to the cradle of guns and the functioning of a unified device is carried out as follows the basics: for 125 mm 2A46M and 2A46 tank guns, the support is attached to the breech of the gun with two bolts passing through the bushing, the spherical end of the screw is fixed in a special socket of the cradle; for 125 mm of the 2A75 anti-tank gun, the mounting is similar, but since the distance between the breech of the gun and the guides with the cradles of the cradle is 197 mm, it is necessary to fix the sleeve to the breech of the gun with two bolts passing through the support. Screwing and unscrewing the screw into the breech of the gun with a ratchet, the process of artificial rollback occurs Thus, the developed constructive technical solution of a unified device for pulling the trunks of products 2A46, 2A46 M, 2A75 is aimed at changing the composition of the group spare parts kit for the above products and, accordingly, including the MPC-AWP workshop from the set of mobile repair bodies, and It can be used during repairs, monitoring of technical condition and number types of maintenance in the field.

Description

The utility model relates to artillery weapons and can be used at repair enterprises for monitoring the technical condition, carrying out repairs and numbering types of technical maintenance of products 2A46, 2A46 M, 2A75 to perform artificial rollback to check the condition and operation of the accelerator, the gap between the breech and copier, the state of the buffers, the inner surface of the roll cylinder and the outer surface of the rods of recoil devices.

Known technical solutions that are part of a group set of spare tools and accessories (SPTA) and designed for artificial rollback of product trunks 2A46, 2A46 M, 2A75 [1-3].

At present, the artificial rollback of the barrel of the product 2A75 is performed using the barrel pulling device shown in FIG. 1, which consists of a ratchet key 1, screw 2, support 3, bolts 4. In turn, the design and type of cradles of artillery guns 2A46, 2A46M, 2A75 are different, which does not allow for artificial rollback using the barrel retraction device shown on FIG. 1, and requires a search for technical solutions aimed at its unification, which will allow artificial rollback of products 2A46, 2A46M, 2A75 with one unified device. Thus, the foregoing determines the relevance of the development of this utility model.

The purpose of the utility model is the unification of devices for pulling the trunks of products 2A46, 2A46M, 2A75.

The advantage of using the proposed utility model, the composition of which is presented in FIG. 2 is:

the possibility of application for products 2A46, 2A46 M, 2A75;

the ability to include in the equipment workshop MRS-AWP from a set of mobile repair bodies for repairing missile and artillery weapons in the field.

The difference from the standard devices for pulling trunks of the above products is:

the possibility of using a unified device, regardless of the type and design of the cradles of artillery guns 2A46, 2A46 M, 2A75.

The technical result consists in changing the composition of the group set of spare parts for products 2A46, 2A46 M, 2A75 by replacing the standard devices for pulling trunks with one unified one.

The technical result is achieved due to the fact that the unified device for pulling the trunks of products 2A46, 2A46M, 2A75, which is shown in FIG. 2 can be made in the form of a constructive solution consisting of a screw 2, a support 5, a sleeve 6, two bolts 7.

Mounting the guns to the cradle and the functioning of the unified device is as follows (Fig. 3):

for 125 mm tank guns 2A46M and 2A46: the support 5 is attached to the breech of the gun with two bolts 7 passing through the sleeve 6, the spherical end of the screw 2 is fixed in a special socket of the cradle;

for a 125 mm 2A75 anti-tank gun, the mounting is similar, but since the distance between the gun breech and the cradle guide rails is 197 mm, it is necessary to fasten the bushing 6 to the breech of the gun with two bolts 7 passing through the support 5.

Screwing and unscrewing the screw-ratchet 1 screw 2 into the breech of the gun, the process of artificial rollback occurs.

Thus, the developed constructive technical solution of a unified device for pulling trunks of products 2A46, 2A46 M, 2A75 is aimed at changing the composition of the group spare parts kit for the above products and, accordingly, including the MPC-AWP workshop from the set of mobile repair bodies into the equipment and can be used when carrying out repairs, monitoring the technical condition and number types of maintenance in the field.
