A combined surveying and mapping instrument positioning adjustment device for geological engineering surveying and mapping

Abstract

The invention discloses a combined surveying and mapping instrument positioning and adjusting device used for geological engineering surveying and mapping. The combined surveying and mapping instrument positioning and adjusting device comprises a fixed chuck, a rotating disc, an adjusting seat and an adjusting support, the fixed chuck is provided with a clamping assembly and a rotating gear, the rotating disc is arranged at the lower end of the fixed chuck and is meshed with the rotating gear through a damping gear, the lower end of the rotating disc is provided with a semispherical bulge, theadjusting seat is arranged at the lower end of the rotating disc through a ball seat, a threaded rod and a limiting inserting rod, the adjusting support comprises a sliding sleeve, a telescopic sleeve and a connecting disc, the sliding sleeve is arranged on the lower end of the adjusting seat, an adjusting gear is arranged on the sliding sleeve, the telescopic sleeve is arranged in the inner partof the sliding sleeve and meshed with the adjusting gear through a toothed plate, the connecting disc is connected with the telescopic sleeve, and an adjusting assembly is arranged on the connectingdisc and used for adjusting movement of the telescopic sleeve in the inner part of the sliding sleeve. The combined surveying and mapping instrument positioning and adjusting device used for geological engineering surveying and mapping is reasonable in structural design, accurate and reliable in positioning and adjusting and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of geological surveying and mapping, in particular to a combined surveying and mapping instrument positioning adjustment device for geological engineering surveying and mapping. Background technique [0002] Geological engineering surveying and mapping mainly refers to measuring various information of space and the earth and drawing topographic maps of various information. Taking the shape, size and gravity field of the earth and other planets as the research object, the objects of research and mapping are very extensive, mainly including Various surface features, landforms and underground geological structures, hydrology, mineral deposits, etc., such as mountains, rivers, houses, roads, vegetation, etc.; through geological engineering surveying and mapping, it is possible to understand the geological environment of the work area and discover the problems related to engineering buildings. Geological problems...
