A three-dimensional shape detecting laser beam scanning device

摘要

The present invention relates to a three-dimensional shape detecting laser beam scanning apparatus used for detecting a three-dimensional shape of a large-sized object located at a remote location such as a raw material file of a raw material yard of a steel mill, a thermal power plant, The laser beam scanning device of the three-dimensional shape detector for detecting a three-dimensional shape of a giant object to be detected, such as a raw material file of a laser beam, includes a horizontal rotation shaft provided through a support plate, A vertical encoder installed at one side of the support frame and connected to the vertical step motor, a vertical encoder installed at the other side of the support frame, a horizontal step motor, and a horizontal drive connected to the horizontal rotation shaft, A pulley, a horizontal measuring pulley coupled to the horizontal rotating shaft, And a horizontal encoder connected to another horizontal measuring pulley connected with a belt, so that the measurement accuracy can be improved by constructing a simple and economical compact apparatus than the conventional scanning method using a rotating mirror, It is possible to easily maintain and repair in a harsh outdoor environment.
