MARKING AND/OR LEVELLING DEVICE Russian patent published in 2012 - IPC G01C15/00 

FIELD: measurement equipment.

SUBSTANCE: marking and/or levelling device is a pendulum system for levelling a source of light in a horizontal or vertical position. The pendulum of the marking and/or levelling device, where a source of light is installed, arranged in the form of a source of laser radiation, makes it possible to rotate a source of light it holds relative to the body in at least one spatial direction, and preferably in all spatial directions, and thus set the source of light into a vertical position by facilities for pulse acceleration. The pulse acceleration facilities may be installed on the pendulum support. Design of facilities for pulse acceleration may be both in the form of a vibration device with an eccentric driven by an electric motor, in the form of a jet pulse air blowing device, and also in the form of a magnetic support, on which the magnetic force may be modified. The pendulum of the marking and/or levelling device is equipped with a brake, which makes it possible after vertical levelling of the pendulum with the help of facilities for its pulse acceleration to fix it with friction closure relative to the body.

EFFECT: development of a marking and/or levelling device with a pendulum system of alternative design, with low structural height and maximum short time of stabilisation.
