Problems solved by technology
[0008] The purpose of the present invention is to provide an auxiliary device for on-site surveying and mapping of construction engineering cost to solve the problem that the traditional auxiliary device for on-site surveying and mapping of construction engineering cost proposed in the above background technology is generally a fixed component structure, and it is not provided to tilt the surveying instrument. Adjustable structure, without a structure that can detect the horizontal inclination of the surveying instrument in real time, it is not convenient to correct the level of the surveying instrument, and without a structure that allows the device to be fixed conveniently, the practicability is poor

The invention discloses an auxiliary device for on-site surveying and mapping of construction engineering cost, relates to the technical field of underground tunnel construction support, and solves the problem that an existing device is inconvenient to correct the levelness of a surveying instrument. The auxiliary device for on-site surveying and mapping of construction engineering cost comprises a surveying and mapping instrument. The surveying instrument is fixedly mounted at the top of a horizontal calibration structure. The surveying instrument comprises a control console; the control console is fixedly connected to the front end of the surveying instrument. A surveying and mapping dip angle adjusting structure comprises a hinge shaft and a dial, the hinge shaft is hinged to the bottom of the horizontal calibration structure, and the dial is fixedly connected to the outer curved side face of a hinge shaft. Two groups of adjusting knobs are respectively screwed to enable the hinge shaft to carry out angle inclination adjustment in front, back, left and right directions through linkage, inclination angle adjustment can be carried out on the surveying instrument at the top of the surveying and mapping inclination angle adjusting structure, and the surveying instrument can be horizontally corrected conveniently through cooperation with the horizontal calibration structure.
Description
technical field [0001] The invention relates to the technical field of underground tunnel construction support, in particular to an auxiliary device for on-site surveying and mapping of construction engineering costs. Background technique [0002] Before carrying out large-scale engineering construction, surveying and mapping engineers must measure and draw topographic maps and provide other information materials before they can carry out work such as decision-making, planning and design. Surveying and mapping are required during on-site surveying and mapping. [0003] After searching, for example, the patent No. CN112113549A discloses a construction engineering cost site surveying and mapping device, including a main body, the upper end of the main body is provided with a fixed assembly, and the upper end of the fixed assembly is provided with a display. There is a shock absorbing assembly, the other side of the display is provided with a connecting column, the upper end of...
