Centering rod device for high-precision engineering surveying

Abstract

The invention, which belongs to the technical field of measuring devices, in particular relates to a centering rod device for high-precision engineering measurement. The device comprises a prism, a main combination frame, an auxiliary combination frame and induction frames. The bottom of the prism is fixedly connected with the main combination frame and the auxiliary combination frame. According to the invention, since a main connecting rod with a cross rod is arranged, a defect that a conventional triangle is fixed and cannot incline forwards is overcome, the effect that the triangle can incline forwards during fixation is improved, and combined fixation flexibility is improved; induction piles are combined on the three induction frames, an emitter is arranged on each induction pile and is used for carrying out infrared emission and receiving; when a height deviation occurs at a fixed angle, an infrared receiving module in an alarm device does not receive data or a vibration sensing module vibrates abnormally and a data analysis module carries out alarm working cooperatively, thereby improving the height uniformity of fixing pins, reducing the measurement error caused by the height difference, and guaranteeing the high precision of the measurement data.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a centering rod device for high-precision engineering measurement. Background technique [0002] Engineering surveying has the following main functions on the project. The surveying work in the planning and design stage of the project construction is mainly to provide topographic maps and topographic digital data of various scales. In addition, it also needs to measure for engineering geological exploration, hydrogeological exploration and hydrological testing. . For the construction of important projects or areas with poor geological conditions, it is necessary to observe the stability of the stratum; the measurement work in the construction stage of the project: according to the topography of the project site and the nature of the project, different construction control networks are established as a fixed Then use different lofting methods to transform the design dra...

Problems solved by technology

[0006] The object of the present invention is to provide a centering rod device used in high-precision engineering surveys to solve the problem that the existing centering rod device proposed in the above background is used in high-precision engineering surveys. The relevant instruments are very mature and the measurement accuracy of the instruments is high. , but it is easy to ignore that in the use of the instrument, the conventional triangle fixing method cannot be tilted forward, and it is easy to cause the triangle fixing method to be unstable and less flexible when tilting forward.

If the device as a fixed support is unstable or there is a height deviation in the multi-leg support, it will directly affect the accuracy of the measurement, and there is no effective solution to the problems that easily affect the measurement accuracy such as height errors or external vibrations. way problem
