Abstract

The invention belongs to the technical field of geometric dimension measurement and specifically relates to a smart laser profiler automatic in leveling and direction adjustment. The smart laser profiler automatic in leveling and direction adjustment comprises an electric revolving stage, a wireless communication module, first and second speed reducing step motors, a bearing block with a bearing, a three-dimensional electronic compass and a laser distance measuring sensor. The smart laser profiler realizes automatic leveling and direction adjustment by means of direction indication of the three-dimensional electronic compass and thereby well solving the problems in the prior art. The laser profiler is capable of measuring the form of the section of a tunnel in real time in tunnel construction to determine back break, and also capable of performing long-term monitoring on the tunnel section form after the completion of tunnel construction; the laser profiler is high in accuracy, simple and convenient to operate, and convenient for reuse after dismounting; and the laser profiler is capable of well performing self-leveling and direction correction for base dislocation and torsion caused by geological changes during tunnel monitoring, and further realizes remote control.

Description

technical field [0001] The invention belongs to the technical field of geometric dimension measurement, and specifically relates to a high-precision automatic leveling and adjusting intelligent laser profiler, which is especially suitable for surface shape detection, monitoring and safety warning of arched cross-sections such as tunnels and bridges. Background technique [0002] With the rapid development of high-speed rail, urban underground transportation, and bridge construction, during tunnel construction, under-excavation and over-excavation will affect the installation of tunnel segments. If the segments are installed and the tunnel surface is repaired again, additional labor costs will be incurred and project cost. The installed tunnel segments will loosen due to stress, geological changes, etc. over time, and will fall off in serious cases, affecting the safety of driving in the tunnel. Based on this, the tunnel cross-sectional type detection during tunnel construct...
