Engineering surveying level gauge supporting device and operation method

Abstract

The invention discloses an engineering surveying level gauge supporting device and an operation method. The engineering surveying level gauge supporting device comprises a windproof anti-seismic base, a jacking assembly and a supporting assembly. According to the windproof anti-seismic base, the lead core is fixed to the middle of the upper pressing plate and the middle of the lower pressing plate, so that the positioning precision of the whole structure is guaranteed, and the connection tightness is improved; when the support is subjected to shear deformation, the lead core is forced by the upper pressing plate and the lower pressing plate to be subjected to shear deformation, and the function of dissipating energy is achieved; the windproof anti-seismic base has the advantages of being good in vibration reduction performance and stable in performance, meeting the requirement for the wind resistance function of the base in the field or at a high position, meanwhile being higher in structural firmness, not prone to generating the disconnection problem between components, having a certain elastic vibration isolation effect, being more comfortable to use and reducing the damage situation. The jacking assembly adopts the mode that three lead screws, three third gears and a second gear are matched, synchronous rotation of the three lead screws is achieved, and when the lead screws rotate, the supporting platform can achieve the lifting function.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying and mapping, and in particular relates to a supporting device and an operation method for an engineering surveying level. Background technique [0002] A level (English: level) is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the leveling principle. The main components are telescope, tube level (or compensator), vertical shaft, base and footscrew. According to the structure, it is divided into micro-tilt level, automatic leveling level, laser level and digital level (also known as electronic level). According to the accuracy, it can be divided into precision level and ordinary level. The level gauge is a commonly used instrument in engineering surveying, which mainly uses the principle of sight distance measurement to m...

Problems solved by technology

[0003] Due to the inability to adjust the height of the existing support frame accurately, it brings inconvenience to the measurement of different scenes, and in the actual measurement process, it will also affect the measurement accuracy, and has no protective effect on the engineering measurement equipment, which brings great inconvenience to the engineering measurement. It brings great inconvenience and increases the labor intensity of engineering surveyors, so that the efficiency of measurement cannot be improved, and it is difficult to be popularized and applied.
