Horizontal displacement monitoring beacon scaffold capable of being leveled

Abstract

The invention discloses a horizontal displacement monitoring beacon scaffold capable of being leveled, and the beacon scaffold comprises an X-axis body, a Y-axis body and a Z-axis body which are assembled according to a three-dimensional system of coordinate, wherein the X-axis body and the Y-axis body form a fixed plane; the Z-axis body and the X-axis body or the Y-axis body are connected by virtue of a rotation axis; and the Z-axis body is provided with a scale trough for placing a scale and is also provided with a water level holder used for providing a water level. According to the monitoring beacon disclosed by the invention, a reading is finished by a holder but not an observation person so as to improve the data accuracy and reliability, and the horizontal displacement monitoring beacon scaffold can be applied to longer observation distance. The rotation axis can regulate to cause the round water level to be centerlized to ensure that the Z axis is precisely leveled, and a fixed surface formed by the X axis and the Y axis is combined. According to the horizontal displacement monitoring beacon scaffold, a small steel rule is guaranteed to be integrally vertical to a vertical face on which a monitored objected is position, thereby greatly reducing errors brought by visual inspection.

Description

technical field [0001] The invention relates to the technical field of survey equipment, in particular to a horizontal displacement monitoring target that can be leveled. Background technique [0002] In the field of survey technology, the commonly used target for horizontal displacement monitoring by the line-of-sight method is an ordinary small steel ruler. When using it, one person needs to hold the ruler, and the other person observes and reads it. When observing, use the crosshair of the instrument combined with the visual inspection of the ruler to ensure that the upper and lower planes of the small steel ruler are perpendicular to the elevation of the monitored object, and whether the left and right planes of the small steel ruler are vertical can only be determined by visual inspection. [0003] According to this method, there are three shortcomings: first, the level of the small steel ruler is only controlled by human hands, and the stability is poor; second, the le...

Problems solved by technology

[0003] According to this method, there are three shortcomings: first, the level of the small steel ruler is only controlled by human hands, and the stability is poor; second, the left and right planes of the small steel ruler are only visually measured by human eyes, and the error is too large; The accuracy is low, and when the viewing distance is long, it cannot be read
