Description

The author's certificate No. 27475 describes a device for determining the horizontal position using sighting. In this device, in the field of view of the pipe, a hair is applied connected by means of gears with movement of the pipe in a vertical plane in order to obtain a point at the intersection with the rangefinder circle to coincide with the zero of the graduated rod. Meaning 4) the test is intended to read the horizontal position of the horizontal scale at the appropriate scale.

In the proposed modification of the instrument. The observation tube is mounted on a rack rigidly connected to the keeper. The coupling, the telescope is inserted into the second, allows a slight rotation, as in the horizontal, in the vertical plane, x. In addition, a conical gear is attached to the coupling, interlocking with the same gear mounted on the telescope so that, when the inclination of the pipe to the horizon changes by a certain angle, the telescope rotates at the same angle. When using a vertically or horizontally positioned rail, it is intended to determine the distance, as well as the horizontal and vertical distance, by an appropriate installation.

In FIG. 1 shows a helical longitudinal section of the instrument; FIG. 2- the same cross cut; FIG. 3- 8 different positions of the ocular grid.

On lx gate 7 of a conventional kipregel (Figs. 1 and 2), an attachment of ilkdr 2 is attached; A second cylinder 3 is inserted into this cylinder, which can rotate in the first cylinder. In order to ensure a smoother rotation of the cylinder 3 in the-cylinder 2, at the bottom of the latter there is a thorn 72, which is located. The cylinder can rotate like a hinge.

The outer cylinder 2 is sealed tightly with a ruler 7; to the same cylinder, from the outside, there are attached sromereyny screw 6, which during its rotation can turn, clinging to the tooth //, the inner cylinder 3 in the horizontal plane. A micrometer screw 7 passes through the wall of the cylinder 5, which passes freely through the wall of the outer cylinder 2p in the slot and does not interfere with the rotation of the inner cylinder 3; through the wall of the latter, it passes along the thread, so that with its end it can rest against the lower part of the head 4, which can rotate in a vertical plane on the axis 5, the spring 8 holds the head 4, and with it the pipe //, from an arbitrary movement. The axis 5, tightly fastened to the cylinder 3, passes through the head 4 in the corresponding hole, so that the head 4 itself can only rotate in a vertical plane, and in the horizontal only with the cylinder 3.

A conical gear 9 is tightly attached to the head 4; through this head and gear 9 passes the axis of the coupling 75, which is able to rotate in the hole of the head 4 in the vertical plane.

A pipe / 5 passes through the coupling / 5, which, when the coupling / 5 rotates, in turn, can rotate in the coupling hole, like a shaft in a bearing, thanks to Towy, which has a bevel gear JO attached tightly to the pipe //. with gear 9. A nut / 5, fitted on the axis of the coupling J3, keeps it, and with it the pipe, from moving along the axis.

An axle with a clamping screw / - imikrometrenny-75 is attached to the axis of the coupling 13 to rotate the axis of the coupling 73 with the tube 7 / in the vertical plane, and due to the coupling of gears, to rotate the pipe 77 around its axis.

The eyepiece of the pipe is provided with a grid in which the ranging filaments are replaced by a ranging circle; at the center of this circle intersect horizontal and. vertical thread at a right angle (Fig. 3-8).

When the tool is on a horizontal plane and the tube 1 is in a parallel position with the ruler 7 and perpendicular to the cylinder 2, the mesh threads are designed — one in a vertical position and the other in a horizontal position. When the pipe 77 rotates in a vertical plane, i.e. when tilting or lifting the lens, due to interlocking different bevel gears, it

will rotate around its axis at the same angle at which the tube's axis of sight is inclined to the horizon / 7. The micrometrical screw b makes the pipe move / 7, without rotating it around its axis, only in a horizontal plane, and at a small angle (about 30 minutes).

The micrometer screw 7 produces the movement of coarse A, also not rotating it around its axis, only in a vertical plane and also at an angle of about 30 minutes.

When in use, the device is placed on the base table; In the same way as with a kipregel, crosshair of a pipe is placed on an ordinary rail, placed horizontally or vertically, but perpendicular to the tool and at the same height as it. The horizontal bolt was fixed with the screw f4, the wire mesh was fed with micro-winding screws b and 7 so that the rail zero coincided with the mesh circumference, and then the distance was counted (Fig. 3 and 6). Then, acting with the same screws, brings the pipe mesh to the position of FIG. 4 and 7 and count the horizontal distance. Further, the same screws bring the grid to the position of fig. 5 and 8 and get a vertical excess. After that, the micromtrent screws are set to their former positions, which aligns the sight axis of the pipe in one vertical plane with the edge of the ruler.

The subject matter of the invention. ,

Modifying the device according to ed. U.S.N. 27475 for determining the horizontal position using a horizontal rail sighting, characterized in that in order to rotate the tube around the optical axis when moving it in a vertical plane in the case of being defined as horizontal. laying and exceeding with the help of sighting on a horizontal or vertical rail, the pipe 72 is equipped with a concentric conical gear 7 coupled with gear 9 on the head #.
