Precise surveying and mapping device for engineering surveying

Abstract

The invention provides a precise surveying and mapping device for engineering surveying. The device comprises a support frame, wherein the support frame comprises a base and telescopic rods, at leastthree telescopic rods are annularly arranged on the bottom side of the base, the base is in an annular shape, a horizontal adjusting mechanism is arranged in the base, a mounting plate is arranged ata central through hole of an annular structure of the base, the mounting plate is movably connected with the base through a horizontal adjusting mechanism structure extending out of the side wall of the inner side of the base, connecting screws are arranged in the middle of the mounting plate, and surveying instrument is mounted at the upper end of the mounting plate through the connecting screws.According to the device, the base and the mounting plate are separately arranged, a floating block is movably connected with a ball cage connecting piece, and after fixation of the floating block isreleased, the floating block can drive the mounting plate to move under the action of buoyancy, so that the mounting plate is closer to a horizontal state, a more horizontal mounting environment is provided, the subsequent leveling difficulty of the surveying instrument is reduced, the horizontal precision of the surveying instrument is improved, more accurate surveying data is obtained, and the development prospect is good.

Description

technical field [0001] The invention relates to the field of surveying and mapping instruments, in particular to a precision surveying and mapping device for engineering surveying. 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 support frame for supporting surveying and mapping instruments is required; because the ground conditions of the surveying and mapping ...

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 support frame for supporting surveying and mapping instruments is required; because the ground conditions of the surveying and mapping site are relatively complicated, or uneven, or have large and small Slopes, after the surveying and mapping instruments at this stage are installed on the support frame, they need to adjust the level of the platform through several adjustment screws to ensure the horizontal accuracy of the instrument and the accuracy of the surveying and mapping data. However, the erection of the support frame depends entirely on I feel that the adjustment accuracy of the support feet is low, which leads to insufficient level accuracy of the platform used to install the surveying and mapping instruments on the support frame. Accuracy makes a difference
