AI Technical Summary
The existing foundation pit ground-anchored wall stability monitoring device lacks a front-to-back translation component, resulting in the inability to control the monitoring component after the front side of the device is attached to the foundation pit wall. The entire device needs to be reinstalled, which is a cumbersome process.
The slide rails and sliders are fixedly installed on the upper surface of the base plate, combined with threaded blocks, threaded rods and servo motors to achieve forward and backward translation of the monitoring component. The servo motor drives the threaded rods to rotate and drive the sliders to move, simplifying position adjustment.
Flexible control of the translation of the monitoring component on the upper surface of the device is achieved, which avoids the need for overall reinstallation, simplifies the position adjustment process, and improves operational efficiency.
