Description

Technical field

The utility model relates to military equipment, in particular to equipping shooting ranges, and is intended to improve shooting skills at moving targets.

Prior Art

The shooting skills of the soldiers of the ground forces are practiced when performing shooting exercises using moving, appearing targets. It is most preferable to use inconspicuous, mobile complexes with rising targets that imitate three-dimensional figures of the enemy. The factor that determines the effectiveness of shooting exercises is the time of the appearance and concealment of the target, the implementation of a realistic trajectory of its movement.

A known installation for lifting a target, including a lifting device with a crank mechanism for raising and lowering the target, connected to the base, an electric drive, a mast for attaching the target, a control panel (RF patent No. 2365858, F41H 7/00, published 27.08.2009) . The disadvantage of the technical solution is significant dimensions, which makes it difficult to perform training exercises, as it unmasks the moving target complex. In addition, the installation is distinguished by unreliability of operation due to significant forces in rotational pairs that occur in the initial phase of the target lifting, which can lead to jamming of the mechanism.

The closest technical solution is a target complex containing: an autonomous base part with remote control moving around the range, a target, preferably of a humanoid type, attached to the base part using a mechanism that provides independent lifting and lowering of the target relative to the base part, from horizontal to vertical position, hit registration system (patent publication US 2018299233 (A1), F41J 9/02, published 10/18/2018).

The disadvantage of the known solution is the trajectory of the target movement that does not correspond to the natural movement of a person when lifting. In the prototype there is a rotation of the target around a fixed axis. The natural rise of a person is a complex movement that combines forward movement and rotation.

The technical problem that the utility model aims to solve is to provide a more realistic lifting trajectory for the target, corresponding to the lifting trajectory of a person.

An embodiment of the utility model

The movable target contains an autonomous base platform 1 capable of independently moving around the range. The base platform 1 is equipped with a six-link hinge mechanism 2 having five movable links 3-7 (Fig. 1, Fig. 2).

The hinge mechanism 2 includes: a crank 3 fixed through the hinge 8 on the base platform 1 and connected to the drive (not shown in Figs. 1 and 2). The proximal connecting rod 4 is connected to the crank 3 (closer to the driving link - the crank 3) through the hinge 9. The proximal rocker 5 is installed on the base platform 1 through the hinge 11 and connected to the connecting rod 4 through the hinge 10. The distal connecting rod 6 (remote from the driving link - the crank 3) through the hinge 12 is connected to the proximal rocker 5. In turn, the distal rod 6 is connected through the hinge 13 to the distal rocker 7. The distal rocker 7 is fixed on the base platform 1 through the hinge 14. The target 15, preferably humanoid, is rigidly fixed to the distal rod 6 and in the initial position is located on the proximal rocker 5.

The axes of rotation of the hinges 8-14 are parallel. The crank 3 is rotated by the engine through a gearbox (not shown in Fig.).

In the initial position, the proximal rocker arm 5 forms an angle α from 92° to 115°, preferably 102°, with the distal connecting rod 6. When the angle α is less than 92°, the loads in the hinges 12 and 13 increase significantly in the initial phase of the lifting of the target 15. An increase in the angle of more than 115° leads to an increase in the dimensions of the moving target. Parametric synthesis, taking into account the force analysis, showed that the most preferable is the angle α equal to 102°.

The longitudinal axis 16 and the proximal rocker arm 5, in the initial position before the lifting of the target 15, are preferably parallel. This allows you to minimize the vertical dimension of the moving target.

The angle γ formed by the distal connecting rod 6 and the distal rocker arm 7 is greater than 15°. At smaller values of the angle γ, the reactions in the hinges 12-14 increase sharply in the initial phase of the lifting of the target 15. An increase in the angle γ over 28° leads to an increase in the longitudinal dimensions of the moving target. The most preferred angle γ is 23°.

In the initial position, the proximal connecting rod 4 and the proximal rocker arm 5 form an angle close to π/2.

The use of a six-link hinge mechanism 2 provides a complex trajectory of movement of the distal connecting rod 6 in the form of rotation combined with lifting. This provides a more realistic behavior of the target 15, corresponding to the movement of a person, in comparison with the prototype (Fig. 3-6). At the same time, small reactions are provided in the hinges 8-14, which eliminates the possibility of jamming of the hinge mechanism 2 when the target 15 is raised.

Functioning of a moving target.

When practicing shooting exercises, the base platform 1 moves around the range due to its own movement system. The motion trajectory can be set via a remote control system.

The target 15 is in its original position - horizontally on the proximal rocker 5 (Fig. 1, Fig. 3). This ensures the minimum overall height of the moving target. The location of the target 15 on the proximal rocker arm 5 reduces the load on the attachment point of the target with the distal rod 6 that occurs when the base platform 1 moves over rough terrain.

At the command of the program, the target 15 is lifted autonomously (or received remotely). The target 15 can be lifted both when the base platform 1 is moving and when it stops. Upon the command received, the engine is turned on and the crank 3 is continuously rotated through the gearbox from the initial position (Fig. 3) to the final position (Fig. 6). This ensures the movement of all links 4-7 of the six-link hinge mechanism (Fig. 3-6). The rotation of the crank 3 implements the movement of the proximal connecting rod 4 and through it the rotation of the proximal rocker 5.

The movement of the proximal rocker 5 (Fig. 1 and 2) provides a complex movement of the distal rod 6: counterclockwise rotation and lifting - vertical movement relative to the base platform 1. Due to the angle between the proximal rocker 5 and the distal rod 6 more than 92°, preferably 102 ° a decrease in the magnitude of reactions in hinges 12 and 13 is achieved. This eliminates the possibility of jamming in these hinges. Lifting and turning of the distal rod 6 provides lifting and turning of the target 15 due to its fixation on it.

The lifting and rotation of the distal connecting rod 6 is realized due to its connection with the distal rocker arm 7. At the same time, the fulfillment of the parameters of the links, providing the angle γ in the initial position is greater than 15°, eliminates the jamming of the links in the hinges 13 and 14. When the value of the lengths of the links, realizing the angle is more than 28 °, the longitudinal dimension of the base platform 1 increases.

The six-link swivel mechanism 2 has a large gear ratio compared to the four-link swivel mechanisms.

Thus, fixing the target 15 on the distal connecting rod 6 of the six-link hinge mechanism 2 provides the trajectory of its rise corresponding to the trajectory of the rise of a person. In this case, the reactions created in the hinges exclude the possibility of jamming of the hinge mechanism 2 in the initial phase of the lift.
