Gravity-based rapid automatic leveling support for measuring instrument

Abstract

The invention discloses a gravity-based rapid and automatic leveling bracket for a measuring instrument. The gravity-based rapid and automatic leveling bracket comprises a self-adaptive variable resistance type vibration-resistant hinge mechanism, an electromagnetic locking type leveling platform, a plumb bob type self-leveling counterweight mechanism and a drum type tripod assembly. The invention belongs to the technical field of self-leveling tripods, and particularly relates to a gravity-based rapid and automatic leveling support for a measuring instrument. An electromagnetic locking type leveling platform and a plumb-type self-leveling counterweight mechanism are creatively provided, and a mode of firstly leveling and then installing a measuring instrument is matched, so that the leveling of the bracket is irrelevant to the center distribution of the instrument, but the rotating resistance of a gravity center spherical hinge cannot be too large (cannot be adjusted to be in the flattest state), and the rotating resistance of the gravity center spherical hinge cannot be adjusted to be in the lowest state). In order to overcome the technical contradiction, the invention creatively provides a self-adaptive variable-resistance vibration-resistant hinge mechanism, and the technical effect that the swing resistance is increased along with the increase of the swing speed is achieved.

Description

technical field [0001] The invention belongs to the technical field of self-leveling tripods, in particular to a quick and automatic leveling support for measuring instruments based on gravity. Background technique [0002] Mine, construction site, production workshop and other work sites often need to use high-precision measuring equipment (laser interferometer, laser collimator, total station, etc.) The degree is closely related, and the flatness of the measurement site is difficult to guarantee, so it is generally necessary to set up the measurement equipment on a tripod for measurement. [0003] As we all know, the leveling of the tripod is difficult, and it is necessary to repeatedly adjust the extension length of the three telescopic rods, and observe through the vacuole in real time. Low efficiency and cumbersome steps. [0004] Therefore, a measuring instrument stand that can be quickly leveled and easily operated has become more and more important in the increasin...
