Survey instrument for road measurement

Abstract

The invention discloses a survey instrument for road measurement, and relates to the technical field of survey instruments. The survey instrument comprises a mounting rod, a mounting block is fixedly mounted at the top of the mounting rod, a mounting bin is fixedly mounted at the top of the mounting block, a survey instrument body is fixedly mounted at the top of the mounting bin, the positions, close to the front face and the back face, of two sides of the mounting block are each fixedly provided with a set of hinge pieces, a supporting frame is hinged between the two hinge pieces of each set on the same side, a first sliding groove is formed in the inner side of each supporting frame, a first sliding block is slidably connected into each first sliding groove, and the opposite sides of the two first sliding blocks are connected with adjusting rods. The positions of the supporting frames can be matched with the pothole degree of the road surface, so that the survey instrument can be in a horizontal state on the pothole road surface, then the measurement error of the survey instrument is reduced, the survey of the survey instrument on the pothole road surface is more accurate, and adverse effects of inaccurate measurement data on subsequent engineering are avoided.

Description

technical field [0001] The invention relates to the technical field of surveying instruments, more specifically, to a surveying instrument for road surveying. Background technique [0002] The survey instrument, that is, the total station electronic range finder, is a high-tech measuring instrument integrating light, machinery and electricity. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the manual optical micrometer reading with the automatic recording and display reading, which simplifies the angle measurement operation and avoids reading The generation of errors is widely used in the field of road measurement. [0003] During the survey work, sometimes the staff need to go to the countryside to conduct surveys, but the roads in some villages are uneven, making it difficult to place the surveyor in a horizontal position when placing it, resulting in inaccurate measured data, whic...
