Surveying and mapping instrument tripod

Abstract

The invention relates to a surveying and mapping instrument tripod. The surveying and mapping instrument tripod comprises an instrument fixing base, an adjusting base and three supporting legs. A fixing groove is formed in the upper surface of the instrument fixing base. A bubble type gradienter located on one side of the fixing groove is embedded in the upper surface of the instrument fixing base. An adjusting rod is fixedly connected to the center of the lower surface of the instrument fixing base. The lower end of the adjusting rod is coaxially inserted in the adjusting base, and a hook is arranged in the center of the lower surface of the adjusting base. The upper ends of the supporting legs are hinged to the adjusting base through hinge shafts. The lower ends of the supporting legs are fixedly connected with telescopic legs. Each supporting leg is internally provided with a fine adjustment mechanism. Each fine adjustment mechanism comprises a transmission box and an adjusting screw rod. A telescopic cavity is formed in each telescopic leg in the length direction of the telescopic leg. Each telescopic cavity is internally in sliding connection with a telescopic rod. A supporting foot is arranged at the lower end of each telescopic rod. Each supporting foot comprises a supporting base and a fixing foot. The surveying and mapping instrument tripod is easy and convenient to operate, convenient and fast to adjust, high in measuring efficiency, wide in application range and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping devices, in particular to a surveying and mapping instrument tripod. Background technique [0002] At present, surveying and mapping instruments such as theodolite and total station are usually used in the early stage of project construction for various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry. It is mainly used to support and stabilize the machine head installed on the tripod. In the process of surveying and mapping, various height requirements and various complex ground conditions are often encountered, and the help of the tripod is inseparable. However, most of the tripods in the prior art are only used on flat ground, which to a certain extent cannot meet the terrain use under specific pit conditions, and before the measurement, it is necessary to carry out centering and leveling, so that the center of the instrument is ...

Problems solved by technology

However, most of the tripods in the prior art are only used on flat ground, which to a certain extent cannot meet the terrain use under specific pit conditions, and before the measurement, it is necessary to carry out centering and leveling, so that the center of the instrument is consistent with the ground station. The center of the mark is on the same plumb line, and the horizontal dial on the instrument is at the level. The existing tripod is difficult to operate during the process of centering and leveling, and needs to be adjusted repeatedly, which affects the efficiency of surveying and mapping.
