Surface measuring device

Abstract

The invention discloses a surface measuring device. The surface measuring device comprises a rotating frame, a first rotating shaft and at least one base, wherein the first rotating shaft is pivotally arranged on the rotating frame and is suitable for being provided with a reflector plate, the bases are pivotally connected with the rotating frame, the pivotal axes of the bases are perpendicular to the pivotal axis of the first rotating shaft, and the bases are suitable for being attracted on the surface of a piece to be measured. According to the surface measuring device, by arranging the rotating frame, the first rotating shaft pivotally connected with the rotating frame and the bases of which the pivotal axes are perpendicular to the pivotal axis of the first rotating shaft, multi-angle measurement is facilitated, and the limitation of position selection of instruments erected for measurement is reduced. Moreover, the angle error can be reduced, the authenticity of measured data is ensured, and the measurement operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a surface measurement device. Background technique [0002] In the related technology, during the measurement process of the universal reflector device for steel structure track beam measurement, the reflector should be placed flat, and the measured surface is required to be flat and free of iron slag, and the magnet surface of the universal reflector should be attached to the measured surface, and then Make the reflection sheet correspond to the measured point in the plane projection position, at this time, the center of the reflection sheet needs to face the measured point. [0003] However, in the actual measurement process, the reflector is usually not easy to place flat, which can easily lead to excessive angle errors, make the center deviate from the measured point, and lose the authenticity of the data. Moreover, errors will occur due to the habits of the surveyors w...

Problems solved by technology

[0003] However, in the actual measurement process, the reflective sheet is usually not easy to place flat, which can easily lead to excessive angle errors, make the center deviate from the measured point, and lose the authenticity of the data

Moreover, errors will occur due to the habits of the surveyors when using visual alignment, which will also cause the data to lose authenticity

In addition, the measurement data of the steel structure track is diverse, and the way of placing the reflector will change with the change of the measurement method. On average, three reflectors need to be placed for each measurement, resulting in low measurement efficiency
