SU126764A1 - Electromechanical target installation with remote control of raising and lowering the target - Google Patents

Description

Electro-mechanical target installations with distance-controlled targets are known, having a horizontal axis of rotation of the target, in which plate-like spiral springs, electromagnets or an electric motor are used as the mechanism for lifting and lowering the target.

The disadvantage of these target installations is the presence of complex and expensive equipment, as well as the need to have a high voltage power source at the shooting range, which limits the use of such installations in field conditions for training troops.

A feature of the described installation that is free from the indicated drawbacks is the use of a compressed air cylinder, an electro-valve and a power cylinder, which are simultaneously a counterweight to the target; Such a device of a target installation allows a battery of 24 volts to be used as a power source.

The balloon can be charged under field conditions either from a dispensing bottle, or from a car compressor, or with a conventional hand pump for pumping car tires. One charge of a cylinder up to 10 itm is sufficient for 70-80 operation cycles, installation.

The target installation is equipped with a control panel. The electrical circuit of the installation provides actuation of the electrovalve when the target button is pressed and the latch electromagnet actuates when the target is lowered, by pressing the corresponding button on the control panel or when a bullet hits the target.

FIG. Figure 1 shows the installation with the cover removed, top view; in fig. 2 shows a section along AA-B in FIG. one; in fig. 3 - electrical circuit of the installation.

The electromechanical target installation is a metal frame / inside which axis 4 is supported in bearings 2 and 3 are vertical. With an axis rigidly aligned: target holder 5, bracket 6 and latch sector 7. The target holder is bolted to the target holder by a replaceable target (not shown in the drawing). On the bracket 6 are strengthened: electro-klanan 9 with the bracket bracket 10 and clamp + //; a power nylon and a yoke consisting of a square 12 and a yoke / 5 in which the container 14 is compressed for compressed air. The axis at its end has a valve 15 through which the balloon is charged with air. The cylinder is connected to the power cylinder and the valve when the hoses 16 and tee 17 are connected. The power cylinder consists of a housing 18, at the bottom of which there is a channel 19 for air, a piston 20, a rod 21 and a spring 22. To the frame there is a wedge 23 against the ram of the power cylinder, the bracket 24 with the electromagnet 25 and 26 ohm, as well as the firing pin 27 of the latch 28.

In addition to parts not listed, an end switch and a copier are attached to the axle to raise the latch striker to the upper position, and a locking relay, main relay and electrolytic capacitor on the frame (not shown).

The work of the mechanisms of the target installation is as follows.

In the original position, the target lies on the ground. All knots and parts fixedly fixed to the axis occupy the position indicated in FIG. 1 and 2. At the same time, the piston rod 21 of the power cylinder rests with its upper end on the wedge 23, and the piston 20 itself is in its lowest position. Electrovalve 9 is locked. The latch 28, which holds the target in a vertical position, is pressed by sector 7. The latch drummer 27 is in its highest position. To raise the target, the Ki button on the control panel is pressed — The latch relay P and the solenoid valve P,; ,,, actuates. Electroplane 9 will open the access of compressed air from the cylinder 14 to the power cylinder. Under the action of compressed air, the piston 20 and the rod 21 are mixed to the extreme upper position. The rod 21, striking the wedge 23, will turn the axis 4 by 90 °, as a result of which the target will occupy a vertical position, and the cylinder and the power cylinder will not be transported to the position //. In the extreme upper position of the target 28, it falls into the notch of sector 7 and holds the target in a vertical position. The limit switch disconnects the Rklap winding and closes the SPST circuit. In order to lower the target, you need to push the button K, - This triggers the electromagnet 25, the hammer 27 is released, which turns off the latch 28, and the target falls under its own weight. Limit switch / C / 7 includes a relay circuit P. , „„.

Lowering (falling) of a dummy occurs when a bullet hits a target. Target M has two metal pads insulated from one another, to which the i-iF capacitor is connected in parallel. The pool, the passage through the target, encloses metal gaskets with its case, and the capacitor instantaneously discharges. When the capacitor is charged, the rsch P i: d.te zasche.pkn P, -, “n and the target falls off.
