Double-channel balance level

Abstract

The invention discloses a double-channel balance level which can effectively improve the level measurement precision, the reliability and the working efficiency. The double-channel balance level is provided with a shell, wherein the shell is movably connected to a base through a vertical shaft; a circular balance level and a horizontal placing device are fixed on the shell; a first objective lens and a first focusing lens are sequentially arranged at one transverse end in the shell along the horizontal direction from outside to inside; a second objective lens and a second focusing lens which are coaxially symmetric with the first objective lens and the first focusing lens are sequentially arranged at the other transverse end in the shell along the horizontal direction from outside to inside; an axial double-surface image acquisition device is arranged in the axial middle parts of the first focusing lens and the second focusing lens; a reading device is arranged in a manner of corresponding to the axial double-surface image acquisition device; connection lines of optical centers of the first objective lens, the first focusing lens, the second objective lens, the second focusing lens and the axial double-surface image acquisition device are coaxial.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a dual-channel level that can effectively improve level measurement accuracy, reliability and work efficiency. Background technique [0002] Known level measuring device is made up of a level and two leveling rods. The main structure of the level is to have a shell, which is movably connected to the base through a vertical axis, that is, the shell can rotate around the vertical axis relative to the base, and a circle to indicate whether the vertical axis is vertical is fixed on the shell. The level and the leveling device used to indicate whether the collimation axis is horizontal (tube level and micro-inclined screw or automatic leveling compensator), are equipped with an objective lens, an eyepiece, an alignment lens and a crosshair reticle in the housing The telescope has a sight and so on at the upper end of the housing. When measuring, first place the two l...

Problems solved by technology

[0016] (1) It is necessary to use a special method to detect and calibrate the level before leveling i Angle, but not in the process of leveling the level gauge i It is difficult to ensure the consistency of leveling accuracy for real-time detection and control of angles;

[0017] (2) To ensure that the horizontal distance between the leveling instrument and the two leveling rods is equal, it often consumes a lot of energy and time of the surveyors, which directly limits the improvement of measurement efficiency; In complex terrain environments such as mountains and mountains, it is often impossible to implement leveling because the level cannot be accurately set up in the middle of the two leveling rods.
