MAINTENANCE DEVICE

ART COMPLEXES

The proposed utility model relates to the field of providing combat training for weapon systems (AB).

It is aimed at creating an automated maintenance system (TO) of artillery complexes, which is part of the range of combat training.

Currently, maintenance of artillery complexes in the troops is carried out by the crews of the facilities and specialists of the military units according to the operational documentation for the serviced facilities.

To carry out work in the army, instruments, equipment and tools are used that are included in sets of single and group sets of spare parts, tools and accessories (ZIP) of objects.

During the maintenance of the facility (for example, TO-2), a large number of complex operations are performed that require a significant amount of calculations and adjustments and, accordingly, highly qualified specialists.

Carrying out maintenance takes a lot of time, the high complexity of inspections and the lack of a sufficient number of highly qualified specialists reduces the quality of the work. All this contradicts the requirements for ensuring combat training of artillery complexes.

As an example, we consider the procedure for performing operations “Checking and adjusting the stiffness of an arms stabilizer (STV) in a vertical plane and“ Checking and adjusting the degree of damping of a weapons stabilizer in a vertical plane, provided for by the technical description and operating instructions for the 1AZZ BL1.335.016 TO system.

When determining the stiffness of the vertical guidance drive, a pencil is installed at the end of the gun, and in front of it is a tablet with paper. The barrel of the gun is pulled down (up) with a force of 16 kgf using a dynamometer, the offset of the barrel under the influence of this force is marked with a pencil on the tablet. Based on these measurements, the stiffness of the STV is calculated.

IPC 7 F41A 31/00, 31/02 F41G 5/32, 5/26

When determining the degree of damping, the gun is set to a pointing angle of 8 °, then it is transferred to the loading angle (3 °) and is sharply removed from the loading angle. STV leads the gun to the pointing angle, near which it makes damped oscillations. According to the results of observations of oscillations, the amplitude of the first oscillation and the number of oscillations before attenuation, which are estimated parameters, are determined by the arrow pointer and marks on the guard.

. Due to the low accuracy of the measurement, this operation must be carried out three four times with subsequent statistical processing.

When measuring the minimum speed of rotation of the tower, the operator must use the handles of the control panel to set the minimum stable speed of rotation and keep it unchanged throughout the measurement, and the second crew member using a stopwatch measures the time the tower rotates through an angle of 180 degrees on the scale printed on the pursuit. The speed is calculated manually as l / t 1 / sec.

Many other maintenance operations are carried out by the same methods, and all calculations are performed manually, which requires high qualification and attentiveness of the performers, which, however, does not exclude errors caused by the influence of the human factor, from small inaccuracies to gross misses.

The currently used methodology for the work, the instruments and equipment used, and the time costs do not meet the requirements for the quality and timing of maintenance of artillery complexes and ensuring their combat readiness in modern conditions.

The problem solved by this utility model is the creation of a device that provides maintenance work for artillery complexes with a significant reduction in time spent on maintenance, as well as improving the quality of work performed while reducing staff qualification requirements, including by eliminating subjective errors staff.

The solution to the problem is achieved by combining as part of the proposed device a personal computer with connected to it through a special controller means of communication with the service object and a set of special sensors controlled by a single software. The complex ensures the implementation of all one-way maintenance in an automated mode, processing the results, calculating the parameters and preparing recommendations on the necessary adjustments of the art complex.

In FIG. 1 shows a block diagram of a proposed utility model.

In this diagram:

1.Personal computer.

2. Object communication controller

3. A sensor for recording angular velocity and angular displacement (one of a set of sensors used in various operations).

4. Object of service.

The proposed system works as follows:

1. During maintenance of the armament complex 4, the controller 2 is placed on the armor and is connected to the object using technological connectors. The sensors 3 are installed on the structural elements of the object and are connected to the controller 2. The personal computer programs 1 of the proposed device through the controller 2 provide the necessary actions to the control circuit of the object, measure the signals in the corresponding circuits of the control system, receive the measurement results of the corresponding sensors and determine the necessary system parameters.

So, for example, when determining the stiffness and degree of damping of a vertical guidance drive, calibrated signals are sent to the control circuit of the vertical guidance of the gun and waveforms of the signal are recorded in the feedback circuit of the HV drive and the angular displacements and gun speeds. Having oscillograms of the process of gun movement, it is possible to automatically calculate not only the stiffness of the drive and the degree of damping, but also its other parameters, which are usually determined in separate operations (backlash, moment of imbalance, moment of friction, etc.).

When measuring the minimum rotation speed of the tower, a signal is sent to the control circuit of the horizontal guidance drive, forcing the tower to set the minimum speed. When a steady speed is reached, a feedback signal is recorded in the drive circuit which is directly proportional to the speed. In this case, it is necessary to rotate the tower at an angle of 5-10 degrees, which significantly reduces the time of the operation.

All maintenance work is controlled by the device’s software package, the results of the work are displayed on the screen and on a paper copy for adjusting the artillery system of the object and entering it into the tank form.

The proposed device is accepted for implementation in the on-board information-measuring control system of a control and testing machine (KPM) 1I37.

Its use will reduce the time of maintenance work by 5-8 times and ensure high quality of work by the KPM military crews.
