Vertical surveying instrument convenient to fix for geographical surveying and mapping

Abstract

The invention provides a vertical surveying instrument convenient to fix for geographical surveying and mapping, and relates to the technical field of geographical surveying and mapping devices. Upper limiting plates are fixedly arranged at the upper ends, located on one side wall of a surveying and mapping device, of side plates, middle limiting plates are fixedly arranged on the side plates, and lower limiting plates are fixedly arranged at the lower ends, located on one side wall of a fixing table, of the side plates. Limiting pieces are arranged between the upper limiting plates and the middle limiting plates on the corresponding sides, supporting threaded sleeves are arranged on the walls, away from one side of the surveying and mapping device, of the side plates on the left side and the right side, supporting threaded rods are inserted into the supporting threaded sleeves in a rotary connection mode through threads, and hanging rods are fixedly arranged on the side walls of the closed ends of the supporting threaded sleeves. The open ends of hanging rings are rotationally arranged at the ends, extending out of the supporting threaded sleeves, of the supporting threaded rods through rotating shafts, and the movable ends of the hanging rings movably sleeve the hanging rods. According to the surveying instrument, a large number of clamping structures are adopted, the surveying and mapping device can be clamped on the fixing table conveniently, the surveying and mapping device can be fixedly installed conveniently, meanwhile, limiting structures are arranged on the clamping structures, and the stability of the device during use is guaranteed.

Description

technical field [0001] The invention relates to the technical field of geographic surveying and mapping devices, in particular to a conveniently fixed vertical surveying and mapping instrument for geographic surveying and mapping. Background technique [0002] The geographic surveying and mapping device is installed and fixed by a tripod. When in use, the surveying and mapping device is fixed on the fixed platform above the tripod, and the level of the fixed platform is adjusted to adjust the level of the surveying and mapping device. To ensure the fixing of the surveying and mapping device, It will be fixed by multiple sets of riveting devices, which complicates the loading and unloading between the surveying device and the fixed platform, which is not conducive to the loading and unloading of the equipment. To solve the above problems, a new design of the fixing device is required. Contents of the invention [0003] The object of the present invention is to aim at the de...

Problems solved by technology

[0002] The geographic surveying and mapping device is installed and fixed by a tripod. When in use, the surveying and mapping device is fixed on the fixed platform above the tripod, and the fixed platform is adjusted horizontally. Adjust the level of the surveying and mapping device. In order to ensure the fixation of the surveying and mapping device during use, it will be fixed by multiple sets of riveting devices, which makes the loading and unloading between the surveying and mapping device and the fixed platform complicated, which is not conducive to the loading and unloading of equipment. To solve the above problems , a new fixture design is required
