Description

The invention relates to landfill equipment, in particular to installations designed to display light and medium targets when training to shoot at emerging targets.

Known target installations for firing firearms containing electromagnets for turning the target, controlled by a software disk mounted on the shaft of the electric motor, and.with. USSR No. 243445, 1967, M. cl. F41J 9/02.

Also known are target installations for shooting training, consisting of a frame, a control panel, a mechanism for raising and lowering the target, where the energy of the powder gases of the empty cartridge when firing serves as a power drive for raising the target and setting it in a vertical position, and.with. USSR 153851, 1961, M. cl. F41J 7/04.

The closest analogue to the claimed invention is an automatic target installation for firing from individual small arms, and.with. USSR 378703, 1970, M.C. F41J 1/00.

The common disadvantages of the known target installations include low reliability when working in different climatic zones and the fact that the firing conditions are not close to real conditions when training in shooting at emerging targets.

The purpose of the invention is the approximation of the shooting conditions to the real ones when learning to shoot at emerging targets:

- control of raising and lowering the target (remote and local);

- automatic lowering of the affected target;

- re-raising the affected target after removing the supply voltage from it;

- issuing information about the raised position of the target;

- issuing information about the defeat of the target;

- illumination of the target’s shield at night with infrared light;

- light imitation of small arms and artillery fire;

- Work in a group of several installations.

The goal is solved in that the target installation comprises a housing, inside which an electric drive and a rotary shaft are mounted, on which a holder with a shield is mounted, a control software device and a limit switch, in accordance with the invention, an electronic unit and a gearbox are located inside the housing, the input shaft of which is connected to the motor shaft, on the output shaft is fixed a crank connected by traction with a rotary shaft, the ends of which are protruding beyond the installation casing and a fork shield and spring battery, and on the side wall of the installation housing there is a panel of connectors, fuses and switches, while the installation housing is equipped with a removable hermetically sealed cover, a micro switch is fixed on the gear case, and an electromagnetic disk brake of a permanently closed type is mounted on the input shaft of the gearbox.

The target installation is equipped with a lamp simulating the fire of weapons, inertial sensors for generating a signal about the destruction of the target, clamps and a supporting frame.

Figure 1 shows a General view of the target installation; figure 2 - the main nodes that reflect the kinematics of the target installation; figure 3 - the output shaft of the gearbox with a crank; figure 4 - input shaft of the gearbox with a brake device; figure 5 - target installation with a set of auxiliary equipment.

The target installation comprises a housing 1, inside of which an electric drive, a control software device, a limit switch and a rotary shaft with a target shield holder are mounted.

Inside the housing 1 there is an electronic unit 3 and a gearbox 4, the input shaft 5 of which is connected to the shaft of the electric motor 6, Fig.1. A crank 8 is fixed on the output shaft 7 of the gearbox 4, connected by a rod 9 to a rotary shaft 2, the ends of which are protruding beyond the housing 1 of the installation and they have a plug 10 of the shield holder and a spring battery 11, Fig.2, 3. On the side wall of the housing 1 installation is a panel of 12 connectors, fuses and switches. The housing 1 of the installation is equipped with a removable hermetically sealed cover 13. A microswitch 14 is mounted on the housing of the gearbox 4, and an electromagnetic disk brake 15 of a permanently closed type is mounted on the input shaft 5 of the gearbox 4, Fig. 4.

The target installation is equipped with a lamp 16 simulating fire weapons, sensors 17 of the inertial type for generating a signal about the defeat of the target, clamps 18 and the supporting frame 19, Fig.5.

The housing 1 with a removable sealed cover 13 provide protection against ingress of moisture and dust.

The electronic unit 3 is a chassis on which are mounted: a transformer, a connector block for connection to a target installation and a printing unit.

In the spring battery 11, a tension spring is applied, one end of which is fixed to the finger on the cheek of the plug 10 of the target holder, and the second to the bracket on the housing 1.

On the side wall of target body 1, there is a panel of 12 connectors, fuses and switches for connecting power circuits, controls, and auxiliary equipment.

Simulation lamp 16, inertial type sensors 17, clamps 18 and support frame 19 are auxiliary equipment that provides enhanced functionality of the target installation.

Simulation lamp 16 is designed to show the fire of small arms and artillery.

The inertial type sensor 17 is a device with two normally closed contacts, which are enclosed in a plastic case. The sensitivity of the sensor 17 is adjusted using a special screw on the sensor housing. The sensor 17 is attached to the edge of the target shield using a clamp (not shown in the figures).

Clamps 18 are used as a sensor on target shields with two conductive plates separated by a dielectric layer. Each clamp 18 is screwed to its lining. The support frame 19 is attached to the housing 1 of the target installation.

The target installation works as follows. The signal to raise the target comes when voltage is applied to the electric motor 6 and simultaneously to the electromagnetic brake 15. The electromagnetic brake 15 is released and at the same time the electric motor 6 rotates the crank 8 through the reducer 4, which rotates the rotary shaft 2 and the plug 10 of the target shield holder through the rod 9. When rotating the crank 8 closes the contacts of the microswitch 14. The electronic unit generates a signal "Target raised", at the same time, the power of the electric motor 6 and the electromagnetic brake 15 is turned off, and the engine is braking.

The crank 8 converts the rotational movement of the output shaft 7 of the gearbox 4 into the oscillating motion of the fork 10, mounted on the rotary shaft 2, without using the reverse rotation of the electric motor 6. For half the turn of the crank 8, the rotary shaft 2 is rotated by an angle of 83.6 °.

When a bullet hits the target’s shield, the contacts of the inertial sensor 17 from the shock open, giving a pulse to the electronic unit 3 to generate a signal about the lesion. The electronic unit 3 generates a “Defeat” signal and supplies voltage to the electric motor 6 and the electromagnetic brake 15.

The electric motor 6 through the gearbox 4 rotates the crank 8 and through the rod 9 rotates the rotary shaft 2 and the plug 10 of the target shield holder.

When the crank 8 rotates, the target lowers to the horizontal position, the contacts of the microswitch 14 are closed, the electronic unit 3 generates a “Target lowered” signal, the power of the electric motor 6 is turned off, the power is removed from the electromagnetic brake 15, and the electric motor 6 is decelerated.

During the lowering of the target and its use during lifting, the spring accumulator 11 operates.

Simulation of a single fire is carried out by individual flashes of a lamp of imitation 16, simulation of bursts by a series of flashes.

The pulse for generating a signal in the electronic unit 3 about the defeat of the target shield with two conductive plates is issued from the clamp 18 due to the closure of the plates by a bullet penetrating the target shield.

Impact loads that occur when bullets hit the target’s shield are transmitted to the support frame 19, which ensures their damping. Similarly, the support frame 19 dampens wind loads.

This invention should find wide application in ranges and shooting ranges.
