Description

The invention relates to geodetic instruments, and can be used when leveling with a plane of arbitrary orientation, reproduced at a given angle relative to a vertical line or horizontal level surface.

A device for marking objects is known, comprising a stand, a first column mounted on a stand rotatably around a vertical first axis, a telescope with a horizontal optical axis rigidly mounted in a first column, a second column mounted on a first column rotatably around a second axis,

combined with the optical axis of the telescope, a first penta prism located on a continuation of the optical axis of the telescope, a third column rotatable around a third axis orthogonal to the second axis, and a second penta prism optically coupled to the third third through the first penta prism. The disadvantage of the prototype is limited functionality.

The purpose of the invention is to expand the field of use by making it possible to define inclined planes and measure the distance between points of an object.

The drawing shows the main view of the device.

The device contains a telescope 1 with a self-contouring line of sight, a penta prism 2 and a penta prism 3 with optical wedges 4, located in the carriage 5, which provides the freedom of the measured sensor Ш | И5 | 1е of movement along the guides 1 b,. The ko-yeriyo together with the vertical-HbiNj KpyirpfA 8 imDom make up a column having freedom of rotation around the original sight line of the telescope 1. Pentapriema 2 in the carriage 5 is fixed. A pentaprism 3 in a frame with an optical wedge 4 is mounted on a shaft 9, perpendicular to the original sight line of the telescope 1. A limb 10 is fixed on the same shaft 9. The shaft 9 together with the pentaprism 3 and the limb 10 form a common column with freedom of rotation around its axis, and freedom of translational movement along the same axis by the measured value. An optical sight 11 is mounted on the outer end of the shaft 9, oriented synchronously with the external beam emanating from peitaprism 3. The telescope 1 is mounted on a column connected to a horizontal circle 13 having a horizontal

the limb, the vertical axis of rotation 14, levels 15 and 16. The vertical axis 14 has a through vertical hole for centering the device above the point of terrain. The axis 14 is connected to the stand 17, similar in design to theodolite stands. When leveling the plane of arbitrary orientation, the device is installed so that its working part

located outside the controllable flat surface of the structure, and the optical system of the device could create a line of sight parallel to the controllable plane of the structure. It is convenient to install the device either by falling, or along the strike of a controlled plane. When installing the instrument, set the telescope 1 along the strike, rotate the vertical circle 8 with guides 6 and 7 by a predetermined angle of inclination along the dial, then rotating from the pentaprism 3 will reproduce a plane parallel to the given one. When leveling, a ruler with a normal heel installed on the controlled one is used the plane. The mechanism of the measured translational movement of the shaft 9 with the pentaprism 3 makes it possible to increase the accuracy and simplify the taking of readings along a ruler with a normal five.
