Grade mechanism for tiltable laser optical systems

摘要

Rotating construction laser device with a grade mechanism, including a code element and a position detection device for providing and detecting a feedback position information, and a leveling mechanism, which supports a lens barrel tiltably and is designed to tilt the lens barrel in order to have the level position detected by a tilt sensor and therewith to level the grade arm, the code element or the position detection device is arranged directly on the grade arm, and the feedback position information directly depends on the position of a reference point on the grade arm, the reference point being defined by the code element or the position detection device, respectively, thus allowing to deduce a position of the grade arm directly from the feedback position information, and/or to calculate a tilting angle of the grade arm with respect to the lens barrel directly from the feedback position information.

1. A rotating construction laser device with a grade mechanism, comprising:
a lens barrel in which a laser optical system is disposed; a frame structure that is fixed to, integrated into or directly provided by a part of the structure of the lens barrel; a grade arm, which is tiltably supported on the frame structure in an XZ-plane, the XZ-plane having an X-axis and a Z-axis, the Z-axis being an optical axis of the laser optical system and the X-axis lying within a plane perpendicular to the Z-axis; a tilt sensor which is provided at the grade arm and is configured to detect a level position of the grade arm; a tilting mechanism, which is provided on the frame structure and is designed to tilt the grade arm relative to the XZ-plane; a code element for providing a feedback position information and a position detection device for detecting the feedback position information; and a leveling mechanism, which supports the lens barrel tiltably and is designed to tilt the lens barrel in order to have the level position detected by the tilt sensor and therewith to level the grade arm, wherein: the code element or the position detection device is arranged directly on the grade arm, and the feedback position information directly depends on the position of a reference point on the grade arm, the reference point being defined by the code element or the position detection device, respectively, thus allowing to:
deduce a position of the grade arm directly from the feedback position information; and/orcalculate a tilting angle of the grade arm with respect to the lens barrel directly from the feedback position information.
