Novel surveying and mapping instrument fine adjustment device

Abstract

The invention discloses a novel surveying and mapping instrument fine adjustment device. A structure of the novel surveying and mapping instrument fine adjustment device comprises an objective lens, afine adjustment base device, a connecting base, an eye lens, a focusing wheel, an alloy shell and an objective lens hood, wherein the objective lens is installed in the objective lens hood, the objective lens and the objective lens hood are of an integrated structure, the eye lens is installed on the rear surface of the alloy shell, and one end of the focusing wheel is movably connected with thealloy shell in an embedded mode. According to the novel surveying and mapping instrument fine adjustment device, through a control mechanism, a transmission mechanism is driven, fine lifting and adjustment of an instrument is achieved by a lifting mechanism, through mechanical transmission, adjustment is more stable and precise, during lifting, the stability of a device is not affected, by controlling a rotating control device, a connecting mechanism and a planet wheel set device are driven, according to a principle of a planet wheel, rotating is achieved finally, the problem that a cradle head is loose due to overuse is solved, and the precision of surveying and mapping and the stability of the device are improved.

Description

technical field [0001] The invention is a novel fine-tuning device for surveying and mapping instruments, which belongs to the technical field of surveying and mapping instruments. Background technique [0002] Surveying and mapping instruments, simply speaking, are the various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry instruments used in the planning and design, construction and operation management stages of engineering construction. In order to better realize the mapping of the measured object, a large angle adjustment and fine-tuning are required correspondingly. [0003] However, after the existing technology adopts a large adjustment, the fine-tuning can only be slightly adjusted by manually controlling the angle of the pan-tilt. After a long time, the pan-tilt will loosen and cause inaccurate surveying and mapping, which will affect the measurement data. The error is large and the adjustment is difficult. ang...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of fine-tuning device for surveying and mapping instruments to solve the problem that after the prior art adopts a large adjustment, the fine-tuning can only be slightly adjusted by manually controlling the angle of the pan-tilt. After a long time, the gimbal will loosen, resulting in inaccurate surveying and mapping, affecting the measurement data, large errors and extremely limited adjustment angles.
