Description

P) Elgetomez izureretin includes an optical rangefinder nasal on the eyebrowth of vision, specially assigned to intend the distances by the method of visually impregnated pipes to the rail of the milestone; similar works.

Out of range distances) 1e pasadkn can be sent directly with a stationary tape only for distances up to 200 m.

When the distance is increased from the tool to 700-800, and the accuracy of the rangefinder results is reduced J sta1 ovit unacceptable for traverse moves.

In the description of the inventor, this disadvantage is eliminated by that. that the nozzle is made in the form of two carriages with longitudinal threads, transferred aJOIDix with one relative to the other in the case of the nozzle with a microscopic screw, .1m internal and external threads and designed for 1. for the induced rangefinder integer i fractional wavelength divisions horizontally ω. In addition, the relative measurement distance to 800 m is 1: 1000.

FIG. 1 shows ont 1sche scheme of the nozzle with visual) t |) slaughter; in fig. 2-nozzle design; on fng. 3-nozzle in the plan; on (} zng. 4-7 images of the field of vision.

The range finder (Fig. I) consists of three optical systems: an object /, an eyepiece 2, a telescope n tightly attached to the telescope and. Number of nozzles on the oculum. The eyepiece is visually connected to the base 1, which is made up of a snapshot of a crocco 1a, which, in focal plane 4, looks at the image of the staff, given by the objective of the telescope.

In the transverse opening 5 asadks (. 3) of the manure ioics are movable karst 6 and 7 (. 2), one of them is zak, p, d1Pgu1o. the carriage 6 is connected with M krometrichesk1 M

Zinto.m, and internal with the ini 6 unore screw.

On the external carriage there is a grid with rangefinders 1 9 nits 10. On each corner, the angular distance between them is a, and on the inner carriage 7 there is one nann / U. P) Single-sided carriages in the psnorechny nilindrneykoy hole of the housing J2 nozzles produced drum / o with a microscrew, having on the outside of its surface with HjaroM / g. on the inner side-.

As a result, one turn of the reel L) corresponds to the shifted yarns .9 and JO by the magnitude of the difference in pitch of the screw

/ g ,,

and the inner carriage, having an 11cg1 means of connecting with the drum of the micrometer screw, does not reach the magnitude of Hiara liiiirra.

If you take it at a constant angle, then the number of peiiKu between strings 9 and 10 will change directly to the rail in proportion to the distance from the annular point (lens focal point) to the rail.

To measure the distance between two points, which are located no more than 800 m, a theodolite with a distance measuring attachment is installed over one of the points, and a second distance measuring rail is installed on the second distance meter.

The tool and rail are centered, and the rail must be installed horizontally and perpendicular to the measured line.

The distance measurement is performed in the following order.

Micrometer rangefinder combine donolpnte.chnuyu thread .chevoy rangefinder thread.

The micrometer.m. Screw of the alidade induces the combined threads on the left rail mark, while the rights of the distance gauge are iiirib pacHo; it lives between the rail marks (Fig. 4).

The micrometer screw of the range finder moves like 1) the NORMAL thread with the nearest left mark n |) and the atom will move the extra drink some distance inside (Fig. 5).

They do the rake counting, for which they first need an integer number of rake divisions / o between the right distance range and the left mark on the rail, and then estimate the distance (A /) between the additional thread and the left mark on the rail to 0.1 division. Then with a micrometer of the range finder, re-pointing with a dalyomeric thread on the left mark.

With a micrometer coBMcniaiOT rangefinder gave a numbered drink with a left mark on the rail.

A count is made but peiiKe, dt which is estimated on the basis of the head :; the distance between the extra thread and the left mark is ikn. This count should be close to zero. If the first yavedeini of the left GHD is on a .chedural mark, it is counted according to dpolpitel1, and the yarn is g.

All these observations are one thing.

If the image of the slats is smaller than the distance between the thalimmers, then the measurements are carried out by the method of repetition, as shown in FIG. b and 7.

When measuring the horizontal and vertical angles of the distance meter, the nozzle is not removed.

Sighting is done by drinking extra, by combining with the index, located between the lines and between the endless threads.

II re ate m with m and 3 o about with and with and

The optical window on the eye of the spectator is different, in that it is made of two carriages with long-range yarns, changing one at a time relative to the core and the nozzle with a micrometer screw having internal and external threads and designed to guide the distance-measuring threads. and fractional shares of horizontal divisions pefiKii.
