Subway tunnel deformation monitoring device and method based on three-dimensional laser scanning
The invention discloses a subway tunnel deformation monitoring device and method based on three-dimensional laser scanning, and relates to the field of monitoring devices. The device comprises a bottom frame and a movable rod rotationally arranged on the lower portion of the bottom frame, rail wheels are fixedly connected to the two ends of the movable rod, a supporting seat is slidably connected to the top end face of the movable rod, and a three-dimensional laser scanner is arranged on the top end face of the supporting seat. According to the subway tunnel deformation monitoring device and method based on three-dimensional laser scanning, the fixed box is arranged on the bottom end face of the bottom frame, and the two-way threaded rod capable of driving the movable frame to move is arranged in the fixed box, so that fixed teeth arranged on the inner wall of the movable frame are clamped with a toothed ring arranged on the outer wall of a movable rod; therefore, the chassis and the rail are connected and fixed, and the situation that the chassis and the three-dimensional laser scanners arranged at the chassis change in position under the action of external force, and the accuracy of fixed-point monitoring data of the three-dimensional laser scanners is affected is avoided.
本发明公开一种基于三维激光扫描的地铁隧道变形监测装置及其方法，涉及监测装置领域。该装置包括底架转动设置在底架下部的活动杆，活动杆的两端均固定连接有轨道轮，活动杆的顶部端面滑动连接有支撑座，支撑座的顶部端面设置有三维激光扫描仪。该一种基于三维激光扫描的地铁隧道变形监测装置及其方法，通过在底架的底部端面设置固定盒，固定盒的内部设置可带动移动框移动的双向螺纹杆，以便移动框内壁设置的固定齿与活动杆外壁设置的齿环卡接，进而将底架与铁轨之间连接固定，避免底架以及底架处设置的三维激光扫描仪在外力作用出现位置变动，影响三维激光扫描仪定点监测数据的准确性。
