Description

Instruments are known for solving problems of mountain geometry, for example, determining the spatial arrangement of the wings of a vein, provided with a horizontal limb with an alidade.

A distinctive feature of the described device is that the second limb, inclined relative to the first by an angle of | 3 drops, is placed on the limb of the limb, in the center of which is MOI; TH is mounted on the ball joint by the core of the famous wing of the core at an angle Meetings last with bomber.

FIG. 1 shows a longitudinal section of the device; on f |; g. 2 - view from the side.

The device consists of two parts: an ebonite disk /, combining with a stand, on which two root protractors 2 are installed. The root protractors are planted on alidade 5. Limb 4, which lies at the base of the device, is graduated from O to 360 °. The alidadus is raised on the axis and when the ebony disk is combined / with the alidade, the ebonite disk rotates simultaneously.

On the one hand, the floor of the housing of the device is covered with a textolite disk, and on the other, with an aluminum disk 5 of a disc-shaped form. When assembling the device, the textolite disk is placed on the side of the graduated part of the ebonite disk, and the aluminum plate is on the opposite side.

The trailed form of the aluminum disk, when connected to a textolite disk, causes the formation of a groove, inside which an ebonite disk is placed.

This embodiment serves to fasten together the parts 5 and b were connected with the ebonite disk and rotated about its center.

An (inner) small protractor 7, graded from 0 to 180 °, is pivotally attached to an aluminum plate. On the same side, an external (large) protractor 8, also graduated from 0 to 180 °, rests on the ebonite disk. Large protractor in supports with the number 71562

The articulation link allows it to always be horizontal.

On one of the supports of the large protractor, an auxiliary, small protractor 9 was mounted, on which angles of 6 90-ip are counted.

Through the double-sided external (large) protractor and internal HHii (small) protractor passes the rod JO, the axis of which is set, respectively, behind the strike lines of the famous vein wing.

The rod 10 and the small protractor 7 represent the half-plane of the core R.

The articulation // rod 10 allows the latter to freely rotate inside and the large protractor 8, simultaneously rotating the small protractor 7, thus mating the half-plane of the core P to the displacement plane Q.

The angle of the meeting with the core with the displacer is counted along the large protractor.

The intersection line of the half-plane of the core with the plane of the spacer at any angles: a is the angle of incidence of a known part of the core; p is the eye of the fall and the angle of the meeting of the core by the bias, is a metal rail / 2, carrying at its ends a pair of coils 13 running along grooves fastened with a textolite disk at an angle of 90 ° to the crossing line passing through the supports small protractor.

When the box J4 of the metal rail / 2 device rotates, it moves progressively, taking care of different positions (its position relative to the crossing line of the I and Q planes depending on the angle of slip M.

PRIORITY AREA

Claims (3)

1. An instrument for solving problems of mountain geometry, for example, determining the spatial arrangement of the wings of the vein, equipped with a horizontal limb with a-lidada, characterized in that on the alidad of the decree, the second limb is inclined relative to the first by an angle j3 of the displacement limb, in the center of which a rod is mounted in a ball joint mounted along the strike line of the famous wing of the core at the corner of the corner where the core meets with a displacer in a horizontal section and the angle of incidence of a known part of the core or reservoir in place . 2. The form of the device according to claim 1, from the section with the fact that to install the rod under the corner from the meeting of the ico core, the displacer serves as a hinge propeller to the limb, positioned in the horizontal plane after the limb is installed under the corner the displacer falls, and to install the rod at an angle of incidence of a known part of the core or formation, the second protractor fixed on the alidade of the limb serves as a charlle. 3. The form of the device according to PP. 1 and 2, characterized in that a rail was used to indicate the direction of the lost part of the vein relative to the crossing line of the known wing of the vein, moved by the crank parallel to itself in the direction normal to the crossing line of the limb plane with the vein half-plane on the lost wing of the core according to the position of the slat relative to the center of the limb.
