Description

The proposed utility model relates to the field of artillery weapons and can be used in units for the maintenance and repair of weapons and military equipment (WME), at industrial enterprises when performing technical diagnostics of hydropneumatic systems that are part of WME.

There are various constructive technical solutions designed to perform artificial rollback of tables of artillery pieces, presented in [1-6]. The process of checking the amount of recoil fluid in the knurler of artillery guns, the condition and operation of the accelerator, the gap between the breech and copier, the condition of the buffers, the inner surface of the knurler cylinder and the outer surface of the rods of recoil devices using a unified device presented in [1], as well as using air-hydraulic pump (AHP) [5] is fraught with certain difficulties:

- high laboriousness of the process of artificial rollback of the barrel using a device for retracting the barrel [2, 3] and a unified device [1] due to the use of screw 1 and ratchet 2, which are shown in Fig. 1 (Fig. 1 - performing an artificial rollback using a device for pulling the trunk);

- increased consumption of anti-recoil fluid POG-70 when performing artificial barrel recoil using VGN [5], due to the fact that part of the fluid can remain in the pre-piston space 3 of the working cylinder of the knurler 4 (Fig. 1).

- possible environmental pollution during the performance of work due to the partial outflow of toxic technical fluid into the environment when performing artificial rollback using VGN [5].

- the use of a coupling device, as well as complex systems with the presence of mechanical and electrical connections, which makes it difficult to use the device in the field [4, 6].

The relevance and purpose of developing the proposed utility model are due to the need to optimize the composition of the technological equipment that is part of the mobile maintenance and repair facilities (PSTOR) of rocket and artillery weapons, which will solve the scientific contradiction that has developed in practice, which consists in the ever-increasing requirements for weapons in terms of maintainability on the one hand, and the instrumental base of PSTOR, which remained at the same level, on the other.

The advantage of the implementation of our proposed technical solution when performing an artificial rollback are:

- the presence of a fitting of a quick-detachable connection 5 of FIG. 2 (Fig. 2 - hydraulic cylinder for artificial recoil of artillery pieces), which makes it possible to eliminate the loss of the anti-recoil fluid POG-70 into the environment by ensuring the tightness of the connection and the complete absence of liquid in the pre-piston space 3 (Fig. 1) at the end of the barrel roll.

The technical result consists in eliminating the loss of recoil fluid into the environment during the artificial recoil of artillery pieces.

The technical result is achieved due to the fact that the proposed hydraulic cylinder for artificial rollback of artillery pieces, shown in Fig. 2, can be made in the form of a constructive technical solution, consisting of the following elements: cylinder 6, with a rod 7 located in it with a piston 8, a package of sealing devices of the cylinder 9, sealing devices of the piston 10, in which a fitting of a quick-detachable connection 5 is installed, made with the possibility of ensuring the tightness of the connection, while the sealing devices of the piston 10 with a quick-detachable connection fitting 5 and the piston 8 are made with the possibility of complete removal of liquid from the pre-piston space 3 at the end of the barrel roll.

The process of performing an artificial barrel rollback using the proposed utility model is shown in Fig. 3 (Fig. 3 - the procedure for performing artificial rollback of the artillery system barrel using a hydraulic cylinder for artificial rollback). The principle of performing artificial rollback is based on the interaction of the hydraulic cylinder rod 13 (Fig. 3) of the proposed utility model with the rod of the knurler 14 of the artillery system, while the design of the proposed hydraulic cylinder makes it possible to roll the rollback parts automatically due to the displacement of the working fluid from the cavity of the cylinder 15 of the proposed utility model under the action of pressure of air (nitrogen) located in the working cylinder of the knurler 16 of the artillery system.

The algorithm for performing artificial recoil of the barrel using the hydraulic cylinder we offer is presented below:

- using a threaded connection 12 on the nut 11 (Fig. 2), the hydraulic cylinder 17 (Fig. 3) is connected for artificial recoil with the knurled cylinder of the artillery system;

- after attaching the hose from the hydraulic pump to the fitting of the quick-detachable connection 5 (Fig. 2), the working fluid is supplied to the pre-piston cavity 15 (Fig. 3) and rolled back to the required value;

- the necessary measurements are performed, after which the rolling parts are automatically rolled by opening the hydraulic pump valve, which allows the air (nitrogen) pressure in the knurler 16 to return the rolling parts to their original position.

Thus, the use of the hydraulic cylinder proposed by us for artificial recoil of artillery systems will improve the maintainability of weapons, reduce the laboriousness of performing work when performing checks of the technical condition of recoil devices, and increase the ergonomic indicators of the maintenance process of artillery systems.
