Fixed-point surveying and mapping tool for building planning

Abstract

The invention provides a fixed-point surveying and mapping tool for building planning, and belongs to the technical field of building planning. The tool comprises a mounting platform, a positioning device and three groups of supporting devices. The mounting platform comprises a fixed table and a mounting table. Two frame plates are fixedly arranged at the top of the fixed table, and the mounting table is rotationally erected between the two frame plates through a first rotating shaft, and is driven by a first drive device. The positioning device comprises a connecting column and a positioningcolumn in threaded connection with the connecting column. A ring is slidably arranged on the surface of the connecting column. The tail end of the positioning column is a tip. Each supporting device comprises a connecting rod, a balance weight device and a supporting rod. Two ends of the connecting rod are rotationally connected with the supporting rod and the circular ring respectively. The balance weight device comprises a balance weight block and a supporting leg rotationally connected with the supporting rod. Long-strip-shaped through grooves are formed in the supporting legs in the lengthdirection, and the balancing weights are driven by a second driving device to be movably arranged in the long-strip-shaped through grooves. The device provides a supporting effect for various instruments, the gravity center of the device can be adjusted, and fixed-point setting is achieved.

Description

technical field [0001] The invention relates to the technical field of architectural planning, in particular to a fixed-point surveying and mapping tool for architectural planning. Background technique [0002] Architectural planning refers to the design to meet certain construction purposes (including people's requirements for its use function and its visual experience), and it is necessary to carry out fixed-point surveying and mapping of various data of the location of the building, such as the actual The area, slope angle, and actual topography and other data are used for fixed-point surveying and mapping, and the surveying and mapping results are used as the basis for architectural planning. [0003] At present, it is necessary to use various instruments in surveying and mapping, such as theodolite, level and distance meter, etc., and a surveying and mapping tool for supporting the surveying and mapping instrument is required; because the ground conditions of the survey...

Problems solved by technology

[0003] At present, it is necessary to use various instruments in surveying and mapping, such as theodolite, level and distance meter, etc., and a surveying and mapping tool for supporting the surveying and mapping instrument is required; because the ground conditions of the surveying and mapping site are relatively complicated, or uneven, or have large and small Slopes, the positioning devices of surveying and mapping instruments at this stage cannot be stably fixed on such ground; if there is a certain slope or potholes in the surveying and mapping site, it is very easy to dump due to the unstable center of gravity
