Description

Mechanisms for automatic leveling of the mniomet are known.

A mechanism for automatic leveling of the mortar sight is proposed, based on the principle of leveling only the aiming device using the axis of rotation of the sight parallel to the axis of the barrel of the mortar.

The peculiarity of the proposed mechanism lies in the fact that to connect the sight with the two-leg, a horizontal axis was used, reinforced in the upper part of the two-leg, on which iiac ;. bushing with a finger, finger with a hinge joint; connected to an axis perpendicular to the plane of the protractor of the sight, t; n that the axis and the finger are always parallel to each other and perpendicular to the horizontal axis.

A schematic diagram of the mechanism is shown in FIG. 1; The construction of the mechanism in a simplified, partially cut-away view is shown in FIG. 2

The plane of the protractor for setting the aiming angles is brought to a horizontal position along the transverse level. To bring the plane of the protractor into a horizontal position by rotating around the axis of the axis parallel to the axis of the mortar barrel, an axis AB is installed on the sighting device, perpendicular to the plane of the protractor. If in the process of laying a mortar to keep this axis in a vertical position, then the plane of the protractor will always be in a horizontal position.

A horizontal AU axis is attached to the two-leg, always remaining from the n plane of the two-leg. The torsion axis ED is carried out at

Screw K assistance. A sleeve is mounted on the ED axis with the GF finger perpendicular to the ED axis fixed on it.

Plank I, at the ends of which two vzlkas with knob holes are fastened, connects the finger GF and the axis AB, on which the bar is worn with its bushings. Thus, the axis AB always remains parallel to the axis of the finger GF and perpendicular to the axis ED.

When setting the sighting angle, the longitudinal level is brought to the middle with a screw of the lifting mechanism. Thereby, the axis AB and the finger OF are brought into a vertical position. Thus, the removal of the transverse level with the help of screw K. and the level of the screw of the lifting mechanism eliminates the need for a leveling mechanism for the whole mortar.

Subject invention

The mechanism for automatic leveling of the mortar sight, based on the principle of leveling only the aiming device using the axis of rotation of the sight, parallel to the axis of the mortar barrel, from the shaft of the mortar and reinforced axle. the upper part of the two-leg, which is fitted with a bushing with a finger, the latter is connected by an articulated joint to the axis, perpendicular to the plane of the goniometer of the sight, so that the axis and the finger are always parallel to each other and perpendicular Kulrny leveling axis.
