Tripod capable of being fast leveled

Abstract

The invention discloses a tripod capable of being fast leveled. The tripod comprises a base, three supporting legs and a leveling fixed seat, each supporting leg comprises a sliding seat and a sliding rod, a locking knob is fixedly arranged on each sliding seat, the fixed supporting legs are connected with the base through the locking knobs, and supporting feet are arranged at the ends, away from the sliding seats, of the sliding rods. Precision adjusting mechanisms are arranged between the sliding seats and the sliding rods, and the length of the supporting legs can be precisely adjusted through the precision adjusting mechanisms. The leveling fixed seat is arranged on the base and comprises an equipment mounting seat, a linkage fixed plate and a plurality of leveling knobs, measuring equipment is arranged on the equipment mounting seat, the leveling knobs are arranged on the lower portion of the equipment mounting seat and used for precisely adjusting the flatness of the equipment mounting seat, and the linkage fixed plate is clamped on the leveling knobs. The tripod has three adjusting methods of rough adjusting, precise adjusting and fine adjusting, the tripod can be unfolded, leveled, dismounted and stored fast, the leveling precision of the tripod is high, the leveling error can be controlled within 20 degrees, the precision stability is high in the long-term work process, and the precision stability is slightly influenced by environment temperature changes.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a fast leveling tripod, which is used to provide a stable working platform for instruments and equipment such as theodolite, collimator, north finder, and inertial combination when used indoors or outdoors. Used in geodetic surveying, civil engineering, bridge construction and other fields. Background technique [0002] In the field of measurement, when measuring equipment such as theodolite, collimator, north finder, inertial combination, etc. are used indoors or outdoors, they usually need to be fixed by a stable and flat working platform for accurate measurement. In the prior art, measuring instruments or equipment are generally installed and supported by a bracket with a working platform, especially a telescopic or foldable tripod. [0003] Present various forms of tripods, for the convenience of carrying, unfolding and withdrawing, basically all adopt the fo...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of adaptability of the existing tripod in the construction site and field environment, and provide a quick leveling tripod, which can be adjusted in three ways: rough adjustment, fine adjustment, and fine adjustment, so as to ensure its performance. Rapid deployment and leveling, the leveling accuracy of the entire tripod is within 20", and the stability is good during long-term work. It can be used normally in the laboratory and in the field when the maximum inclination angle of the ground is 25°.
