AI Technical Summary

Technical Problem

Existing tunnel structure measurement equipment requires frequent manual adjustments to the measurement angle and position, which is cumbersome and the measurement accuracy is easily affected by human factors, resulting in low measurement accuracy.

Method used

Design an electric rotary terminal for tunnel structure measurement. By installing a first rotating component on the outside of the base and a second rotating component on the upper side of the slip ring, the laser emitter can be automatically rotated at multiple angles in the horizontal and vertical directions to cover various parts of the tunnel structure.

Benefits of technology

It achieves full coverage of the laser emitter within the tunnel structure, obtaining comprehensive and accurate three-dimensional coordinate information of the tunnel structure, ensuring the accuracy and reliability of the measurement, and avoiding measurement blind spots.

Abstract

This application discloses an electrically operated rotary terminal for tunnel structure measurement; it includes a mounting base, a first housing, and a second housing. A first rotating assembly is disposed on the outer side of the mounting base and connected to the first housing. A battery is disposed at the lower part of the first housing, and a fixed seat is disposed at the upper part of the first housing. A driving component is disposed on the lower side of the fixed seat, and a slip ring is disposed inside the fixed seat. A second rotating assembly is disposed above the slip ring, and the slip ring is connected to the driving component and the second rotating assembly. The second rotating assembly is connected to the second housing, and a control board and at least one laser emitter are disposed inside the second housing. This application utilizes the first and second rotating assemblies to achieve multi-angle automatic rotation of the laser emitter in both horizontal and vertical directions. This allows the laser emitter to cover all parts of the tunnel structure, avoiding measurement blind spots and ensuring the accuracy and reliability of tunnel structure measurement.
