Description

Level gauge for railway engineering survey

technical field

The utility model relates to a level instrument, in particular to a level instrument for railway engineering survey.

Background technique

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. Levels appeared after the invention of telescopes and levels in the 17th and 18th centuries. At the beginning of the 20th century, the micro-tilt level was produced on the basis of the inner focusing telescope and the coincidence level. In the early 1950s, an automatic leveling level appeared; in the 1960s, a laser level was developed; in the 1990s, an electronic level or a digital level appeared. At present, there are many leveling instruments used in railway engineering. The traditional leveling instrument has low precision, and the operator reads the bubble scale value visually. The subjective reading error is relatively large, the measurement accuracy and accuracy are low, and the measurement efficiency is low. The height of the level gauge is not adjustable, which does not meet the needs of use.
